暑假的收获

第1篇:暑假的收获范文

什么是牛奶?牛奶就是小牛犊每天吃的香甜的饭;什么是健康?健康就是不生病。我喜欢香醇的牛奶,更喜欢健康快乐地生活。

“早一杯,晚一杯,常喝牛奶身体好。”妈妈总是这样对我说,她说:“早上喝一杯牛奶可以提精神,一天都有劲;晚上喝一杯牛奶能让你很快进入梦想,睡个好觉!”虽然妈妈总是要求我多喝牛奶,可我以前从来都不主动喝,因为我想我都10岁了,怎么还能像小婴儿似的天天喝奶呢,让人多笑话呀。这个暑假我在家看了一期中央电视台的《健康之路》节目,有两个健康专家向观众们介绍牛奶对人的好处,他们说:牛奶里面含有和人体很接近的优质蛋白质,含有的25种氨基酸是其他任何一种动物性食物都无法比拟的。牛奶还含有很丰富的钙,而且是最容易被人体所吸收的。其他益处还包括比如睡前喝牛奶有益于睡眠,美国科学家还提出牛奶可以预防肿瘤等疾病。牛奶里面含有的抗体可以增加人体的抵抗力,经常喝牛奶可以增加免疫力。除了讲解外,专家还让观众看了他们的试验:就是跟踪调查北京地区的中小学生,喝牛奶的孩子在骨骼发育和身高明显高与不喝的孩子。看了这个节目,我吓了一大跳,原来我个子矮都是因为以前不爱喝牛奶。

从那天开始,我每天早晚都主动到冰箱里取牛奶,喝完牛奶再做别的事情,妈妈说这是我本次暑假里的最大收获

第2篇:暑假的收获范文

我在这个暑假里收获很多,可以说是一箩又一箩。

放暑假了,我不用去上学,自已掌握的时间就更多了。我不像其它的小朋友那样玩电脑、看电视……而是去学一些课外知识。我参加了奥数班,英语班、游泳班.而且还到一位老师家学习写作呢。虽然每天的时间都安排得满满的,但我一点也不觉得辛苦,反而过得很充实。我觉得自已解答数学题的能力增强了;积累的英语单词量更加丰富了;作文的表达能力也有了一定的提高;游泳的技能更是得到了飞速的进步。

我最大的收获是观看奥运节目。我利用休息的时间来打开电视,看奥运节目。我从电视里看见了许多出色的运动员,他们拿了很多奖牌,当记者问他们拿到了这枚金牌,想说些什么的时候,运动员们就会说:“我为了拿这枚金牌,付出了许多汗水和许多精力。我觉得想要取得成功就一定要付出努力。”他们的话让我思考了很久很久。

这个假期我对我们阜新市清河门的佰特英语辅导学校进行了一次社会调查,主要是针对他们的完善教学模式做一下了解,进而学习他们的方式方法,不仅锻炼了自己同时也受益匪浅。从佰特人身上我深刻的体会到了一种精神,那就是坚持的精神。

从小到大我们一直在用“坚持”二字激励自己,当我们学习困乏时,我们需要坚持;当我们长跑时,我们需坚持;当我们接近成功却要放弃时,我们需要坚持......坚持无处不在,在某种程度上讲它是我们的精神支柱,今天我明白只要坚持,我们一定能行!

曾经看到过这样一个故事。

新生开学。

“今天只学一件最容易的事情,每人把胳膊尽量往前甩,然后再尽量往后甩,每天做300下。”老师说。

一个月以后有90%人坚持。

又过一个月有仅剩80%。

一年以后,老师问:“每天还坚持300下的请举手!”整个教室里,只有一个人举手,他后来成为了世界上伟大的哲学家。

这是个真实的故事,让我们记住他的名子吧!他就是柏拉图,一个伟大的哲学家。

从这个故事中可以发现:成功没有秘诀,贵在坚持不懈。任何伟大的事业,成于坚持不懈,毁于半途而废。其实,世间最容易的事是坚持,最难的,也是坚持。说它容易,是因为只要愿意,人人都能做到;说它难,是因为能真正坚持下来的,终究只是少数人。巴斯德有句名言“告诉你使我达到目标的奥秘吧,我唯一的力量就是我的坚持精神。”

大学来到学校参加工作以来,亦曾有过放弃的念头,但总被他们的执着和坚持感动。曾在《我的期货梦想》中看到“我喜欢期货的神奇和魔力,经过无数绿肥红瘦的日子,前方的路充满荆棘和考验,坚持不懈才会有梦想和希望。”如今的我,也在努力并坚持着,不过是想做得更好而已。

人的一生又何尝不是如此?从“昨夜西风调碧树,独上高楼,望尽天涯路。”到“衣带渐宽终不悔,为伊消得人憔悴。”再到“众里寻她千百度,蓦然回首,那人却在灯火阑珊处。”都应该坚持,坚持生命的困惑、领悟和真谛。只有如此,在你到暮年的时候,细细回想起来,才会觉得没有虚度曾经美好的年华,才会觉得自己的整个生命都充满价值。

【关键词】: 火焰原子吸收 测定降水 钾钠钙镁

中图分类号:P426.6 文献标识码:A 文章编号:

用空气—乙炔火焰原子吸收法测定降水中的钾钠钙镁时,存在着一定的电离干扰和共存离子的化学抑制干扰。

在高温火焰中,钾钠不仅易发生电离而且彼此也互有影响,在分析试样中需加入一定量更易电离的铯盐作消电离剂,以消除电离干扰。

钙镁则受到水样中存在的铝、硅酸盐、磷酸盐和硫酸盐的抑制,其原子化效率明显降低而产生负干扰。此时我们需加入一定量锶、镧或其它释放剂来消除干扰。

但究竟这个消电离剂和释放剂的加入量多少更合适,能使样品测试准确度更高,我们做了具体的实验来验证。

1实验

1.1仪器和主要试剂:岛津的 AA-6701F原子吸收分光光度计;钾、钠、钙、镁空心阴极灯;50毫升具塞比色管。

钾、钠、钙、镁标准使用液浓度分别为钾浓度:0、0.5、1.0、2.0、3.0、4.0、5.0mg/L钠:0、0.25、0.5、1.0、1.5、2.0、3.0mg/L钙:0、0.5、1.0、2.0、3.0、4.0、5.0mg/L镁:0、0.1、0.2、0.3、0.4、0.5、0.6mg/L。

钾钠消电离剂:1%硝酸铯水溶液(称取2.9 g硝酸铯(CsNO3)溶于水,定容至200毫升 ,此溶液1.0毫升含10毫克铯)

钙镁释放剂:1%锶盐溶液(称取3.0g氯化锶(CrCL2.6H2O)溶于水,定容至100毫升 ,此溶液1.0毫升含10毫克锶)

做钙、镁时,国际方法GB11905-89选用的释放剂氧化镧,其水溶性差,配制过程中得用硝酸溶液溶解,蒸至近干,加10毫升硝酸溶液及适量水,微热溶解,冷却后用水定容。这样配制出的镧盐实际做样过程中空白太高。在本实验中我们选用的是氯化锶,其水溶性好,配制方便,且空白较好。

仪器参数的调试根据不同型号仪器自行选择,这里不做赘述。

1.2实验具体数据

2实验结论

根据以上图表测试数据可以看出,加入不同量的消电离剂,钾钠的测试结果是有区别的,从图中可明显看出,加入量过多或过少,其测试准确度均不够理想。这一点在钙镁的测试中也有充分体现。测试数据显示只有加入0.5毫升的消电离剂和测钙镁用的释放剂,就是说在测试样品中使得铯盐、锶盐溶液的浓度保持在0.1毫克每毫升,此时其测试结果最为理想。

3其它注意事项

一定要注意选用试剂的纯度。我们有一次做降水钾钠含量的检测,方法是用原子吸收火焰法,我们的具体方法是按照所需的浓度来配置了标准溶液,为了消除电离,在标准溶液和空白及供试液(都为50ml)中都加入了0.5ml的1%硝酸铯水溶液,结果在测量的时候发现空白很高吸光度都达到1.2几了,以致于影响了其他的测量无法正常进行。

所以测试前必须先检查一下这些试剂的纯度。具体做法是看不加抗干扰剂的空白情况。如果正常,就基本可以确定是试剂不纯了。

另外用原子吸收测定钾钠时,通常当有较高空白时,若排除了试剂不纯的原因, 或者是容器或水污染造成的原因外,那主要是由于蒸馏水产生,测钾钠时不能用去离子水,要用纯净水或双蒸水。

扣空白是有一定要求的,空白太大会掩盖样品信号。当测试低含量的钠时,空白影响的效果就更明显。一定要在样品处理过程加带空白并在测量时做扣除。

在抗干扰剂使用剂量的选用同时,我们在用原子吸收做钾和钠时,由于其灵敏度很高,要注意器皿、试剂、尘埃等均会带来污染,如果是测痕量钠,全程都用塑料器皿。如果是要做高浓度的钾钠,目前通用的方法是将燃烧头转动一个小角度,减小吸收光程去做,简单易行。

由于钾钠钙镁之间有相互影响因素,加入抗干扰剂效果不是很好时,建议采用标准加入法对四种元素进行测定,这样更能保证结果的准确性。

Varicocele (VC) is a common disease of young men, the incidence is about 15% in young and middle-aged men[1]. It is a common cause of male infertility, male sterility brings a lot of damage to some families, for which VC need surgical treatment is always controversial, the effect of surgical treatment in patients with different types of VC perform very inconsistent, but most of the studies didn't have clearly classified for patients with VC. This study focuses on the value of surgical treatment to varicocele-associated severe spermacrasia or azoospermia patients.

1 MATERIALS AND METHODS

1. 1 Materials: 20 varicocele-associated severe spermacrasia (sperm density less than 2 million per ml ) or azoospermia patients have been diagnosed by the Affiliated Hospitla of Qingdao University in August 2012 to August 2013(excluding other causes of severe spermacrasia or azoospermia, among them the former is 12 cases , the latter is 8 cases, gas pains of scrotum is 5 cases), 10 varicocele-associated severe spermacrasiaor azoospermia patients refused high ligation of varicocele as control group. The age is 17 to 35 years old, the average age is 23 years old; The course of disease: 3 months to 4 years.

1.2 Research methods

1.2.1 Surgery methods: high ligation of varicocele, surgery time 20 to 40 minutes.

1.2.1 Sperm analysis (sperm quantity, sperm density, percentage of normal sperm, a + b grade sperm vitality) and gonadal hormones(FSH, LH, T, E2, PRL)with radioimmunoassay were measured before operation and 2, 4, 8 months after operation, review and follow-up the patients to realize their condition after surgery.

1.3 Statistical processing: The data are expressed as mean±standard deviation (). Comparisons between groups were made by means of the independent Student's t test, all analyses were analysed with SPSS11.5 software.

3 DISCUSSION

Young male of infertility patients that caused by VC is still more, often occur in the patients that diagnosed VC late and did not receive surgical treatment before puberty . Its main treatment is still surgery, some patients use drug as auxiliary treatment, but results are various. On pathology, VC can undermine the anatomy and function of testis gradually, which may be related to poor testicular blood flow, metabolic disorders of testicular tissue , temperature, increased toxins from the blood and germocyte apoptosis induced by immune factors [2]. The main surgical treatment is high ligation of varicocele(HLV), some reports discuss the clinical effect of the surgery, but the clinic still have controversy about whether VC patients need active surgical treatment or not and which patients should be treated.

This experiment collects , follow-ups 20 cases that varicocele-associated severe spermacrasia or azoospermia patients successfully who received HLV operation ,tests and records the change of sperm analysis , serum gonadal hormone (FSH, LH, T, E2, PRL) in the preoperative 3 days , 2 months after operation, 4 months after operation and 8 months after operation ,and studys , compares , statistical analyzes the above indexes .Result found that sperm count, density and energy of patients have not marked improvement after surgery, postoperative serum gonadal hormone has not obvious change compared with preoperative serum gonadal hormone.PRL in preoperation and postoperation were significantly higher than normal, but other hormones are all in normal range. Compared with the experimental group and control group, the sperm quality and gonadal hormones no significant difference(P>0.05).

Agarwal A and other people carry out Meta analysis about sperm quality of varicocele-associated infertile patients that received surgical treatment , prove that sperm vitality, sperm density and normal morphology sperm percentage all have obvious increase after surgery[3]. SHI Qing and other people apply three kinds of HLV operation to 120 cases of VC , the study found that every sperm indication of three groups patients have not statistical significance before operation, postoperative indications that sperm analysis of three groups were significantly improved compared with preoperation[4]. But none of the above studies according to the pre-operative sperm quality of patients adopt detailed grouping. Peria Zarzuelo E researched 266 cases of two or three degree VC patients that received HLV operation, found that 6 cases of patients have persistent VC , 23 cases of patients produce the main complications - hydrocele, but overall sperm quality has improved significantly after surgery , thought VC need operative treatment[5]. However,Gu Xiang and other people found that high ligation of varicocele is very effective to the patients whose total number of sperm is more than 5×106 ,while unsatisfactory for improving sperm quality of severe spermacrasia or azoospermia patients(the total number of moving sperm< 5x106) by analyzing preoperative sperm result and postoperative sperm activity , restoring index of reproductive function varicocele-associated infertile patients[6]. LI Yajun and other people apply microsurgical ligation of varicocele to 150 cases of asymptomatic varicocele-associated infertility patients from their hospital , preoperative sperm survival rate is 45.31±12.32(%),sperm density is 13.14±8.06(106/ml),3 months after operation is 44.32±11.89(%)、13.65±8.21(106/ml), no obvious change between preoperation and postoperation[7]. But Pasqualotto FF and some people research thought that apply ligation of varicocele to varicocele-associated severe spermacrasia or azoospermia patients can improve the total number of moving sperm and pregnancy rate [8]. This study found that the surgical treatment for varicocele-associated severe spermacrasia or azoospermia patients has no obvious effect, conforms to the research of Gu Xiang et al .

Pasqualoto found that the plasma concentrations of LH and T without obvious difference among three groups of patients ,Serum FSH concentration of group 1 was significantly higher than group 2 and group 3 by retrospectively analyzed infertile male with VC(group 1) ,fertile male without VC(group 2) and fertile male with VC(group 3). And also found that every index has no obvious difference between the VC patients who have no fertility problems and normal men , so he consider whether suggesting VC patients found occasionally in clinic to received treatment deserving consider[9]. WANG Yixin studied 64 cases of varicocele-associated infertile patients , found that sperm survival rate, sperm density is lower than the normal group, FSH, LH and T are all in the normal range, serum gonadal hormones had no statistical difference between preoperation and postoperation, but the postoperative sperm quality improved obviously. And they also found that sperm quality of the patients whose FSH are higher before operation had no obvious improvement ,while whose FSH are normal before operation had statistical difference. They think that according to gonadal hormones measure combined sperm analysis , testicle examination can estimate damage degree of testicle , have certain reference value for the judgment of the operative prognosis [10]. LU Yanfen and some people measured peripheral blood reproductive hormone levels from 93 cases of patients with different varicose degree , found that FSH levels increased, but the three reproductive hormones LH, PRL, T have no statistical significance compared with normal group as the VC degree aggravating , thought that the number of patients with abnormal reproductive hormone levels increased as VC degree aggravating . Reproductive hormone levels had certain reference value which on reflecting the pathophysiological changes of testicular tissue caused by VC[11] .

This study found that postoperative serum gonadal hormone of varicocele-associated severe spermacrasia or azoospermia patients had no obvious change compared with preoperative serum gonadal hormone, PRL in preoperation and postoperation were significantly higher than normal, but other hormones are all in normal range.Serum PRL is a kind of polypeptide hormone , secreted by the anterior pituitary, can promote leydig cells produce gonadotrophin, enhance the number of LH receptor [12]. Physiological levels of PRL can maintain the high level of the T in the testicle, affect the physiological function of deputy sexual gland ,while FSH and T are the main endocrine hormones that start and maintain spermatogenesis[13] , both of them promote testicular seminiferous tubule development, spermatogenesis and mature together , affect the health and reproductive capacity of male offspring directly [14].Serum endocrine hormone measure of azoospermia patients is mainly measure the serum FSH, LH, T and PRL, to confirm whether the testicular function damaged and its damage degree. In this study ,the average of PRL is higher, considering related to testicular damage caused by VC, spermatogenesis ability dropping, PRL feedback-elevated , HLV has no obvious effectin for improving sperm quality and gonadal hormone of severe spermacrasia or azoospermia patients , but the unwell symptoms of five cases of patients who combined scrotum gas pains were significantly reduced or disappeared.

It always exist controversy on varicocele treatment of teenagers. Considering the higher morbidity, some patients were suggested receiving selective treatment . This study thinks that the surgical treatment has no obvious effect for sperm quality of such patients , it is not recommended for severe spermacrasia or azoospermia patients who expect to improve sperm quality to receive surgical treatment, these patients can also consider surgery if they expect to improve the gas pains of scrotum .

My holiday summer

It was the first day of our summer holiday. All of us were very happy. Why? Because we have one months to do things we love to do. We are free.

Although we have some homework. But we can finish them in several days. And the rest time we can make good use of. My god! We have been very tired after hard studying. In summer holidays I want to have full sleepand eat good food in order to replenish myself.

Last but not the least I will have a good rest.

【参考译文】

这是第一天,我们的暑假。我们大家都非常高兴。为什么?因为我们有一个月的事我们都爱做的事。我们很空闲。

虽然我们有一些功课。但是,我们可以完成他们的若干天。其余的时间我们可以好好利用。我的上帝!我们已经很疲惫后很难学习。在夏季假期,我希望能有充分的很好吃的食物,以补充自己。

最后但并非最不重要,我会好好休息。

第9篇:暑假的收获范文

今天距离暑假放假已经过去了半月有余,我一直在思考,我是否荒废了时光?把整天用来学习的时间用去玩游戏,却冠冕堂皇地用休息,缓和心态这般无知的说法去掩饰。我很想说出没有这个词,但事实也许并非我想的那样简单,累,是我对暑假生活的最初印象。

可这也是没有办法的事,一年之后,不,还无须到一年,我就要参加人生中第二次决定命运的考试——中考。我的心情可谓是百般焦急,我不愿输,也不敢输,更不能输。为此,我唯有拼搏努力,为考上理想的高中而奋斗。可这并非光说嘴皮子就可以改变的,想要在短时间内提升我的成绩,暑假的时间必然不可浪费,故我的生活逐渐变得枯燥无味,却又如同机械一般精准。

过不了多久,我就得过着这样一种生活——每天出去散步,散完步回来就做作业,随后就去上补习班,开启一天的学习生涯。可我又有什么办法呢?努力耕耘不一定会有收获,但不耕耘,就一定不会有收获。故唯有拼过,方才能不会后悔,无聊而又无奈的一天!
