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。

第3篇：暑假的收获范文

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】高温爆裂；钢筋性能；检测加固

1.概况

某大型地下室工程，建筑面积约13800m2，框剪结构。工人用氧气切割地下一层挡土墙内侧上的拉杆时，切割引起的火星及灼热钢筋头，从混凝土板预留洞口落到地下二层用于覆盖混凝土的棉被上，引起火灾持续约1小时左右，消防车到现场进行紧急救援。

2.工程受损情况

由于混凝土各组成材料的热膨胀性能不同，在温度较高的情况下，水泥石脱水收缩，而骨料受热膨胀，使混凝土产生很大的内应力，破坏水泥与骨料之间的粘结。而钢材的耐火性能差，当温度达500℃时，强度仅为设计强度的50%左右，当温度达700℃及以上时，强度仅为设计强度的5～10%。随钢筋和混凝土温度升高，混凝土抗拉强度及混凝土和钢筋之间的粘结力显著降低。鉴于现场火灾的持续时间、分布范围、可燃物特性、通风条件、灭火过程等对火灾区域进行温度推断，本次火场最高温度约为930℃。

当用水扑灭时，结构表面急剧冷却在其表面形成很大的收缩应力，混凝土表面首先出现裂缝，进而使结构变得酥松，强度减低，产生许多由外向内的裂纹，导致混凝土爆裂、表面酥松及钢筋外露。

3.检测情况

3.1结构材料性能检测

⑴钢筋力学性能检测：由于火灾造成基础梁侧及负一层顶板的板底混凝土大面积剥落，钢筋外露，经取样检验，受灾后所取钢筋的屈服强度、抗拉强度及断后伸长率虽满足规范要求，但屈服强度均有所下降，最大的达到3.4%，抗拉强度平均下降了12.2%，实测屈服强度与标准规定的屈服强度特征值之比不满足GB1499.2-2007要求。

⑵混凝土强度检测：根椐工程建筑结构类型及现场实际情况，依据相关国家标准、采用回弹-钻芯取样综合法对该工程柱、梁、板进行随机抽样检测，发现部分混凝土强度等级不满足设计要求，主要原因是回弹法与钻芯取样未在同一个侧面，且地下室温度偏低、混凝土日平均温度累计远小于600℃.d：

4.加固方案及注意事项

4.1对受火构件采取增大截面处理的方法进行加固，局部混凝土剥落的构件进行凿除处理后待混凝土表面完全干燥，用环氧树脂水泥砂浆进行抹压平整。

4.2进行表面处理的部位，在施工前必须清理干净且基层必须干燥，严格控制原材料质量，按照混凝土配合比进行施工，确保混凝土强度。

4.3对植筋经拉拔试验合格后方可进行下一道工序，并提供拉拔检测合格报告。组织专人进行监督施工，严格工序交接，符合验收程序。

5.方案实施

将火灾区域的受火构件分为梁板柱三种需要加固的情况。

5.1梁板加固

其操作工艺为：凿除清洗钻孔清孔注胶植筋固化钢筋绑扎模板支设混凝土浇筑拆模强度检测验证。具体操作方法为：

⑴凿除：用手锤、钉子凿除板松散、过火损坏的混凝土至新鲜、坚实的混凝土基面，不得用力过猛，避免造成构件二次损伤。

⑵清洗：用高压水清洗混凝土表面。

⑶钻孔、注胶、植筋等：在受火楼板面钻孔，孔径Φ100mm、梅花形布置、间距1000mm，钻孔时应不损坏楼板钢筋；沿框梁受火面按间距不大于100mm进行冲击钻植筋孔，深度以梁箍筋直径的15倍，用吹风喷嘴清孔至无尘后注胶固化，经拉拉拔检验合格为宜，植筋设直角弯头。

⑷钢筋绑扎：绑扎原梁箍筋同规格、直径钢筋，间距不大于100mm。若梁底筋受损严重还要在梁底植相同规格、直径钢筋，梁截面宽度增加100mm，高度增加100mm。

⑸模板支设：在梁、板经凿除后板下层钢筋网外缘下50mm处支设梁、板模板，模板应清理干净并充分浇水湿润并认真添堵缝隙，减少漏浆。

⑹混凝土浇筑：采用比原设计梁板混凝土高一个强度等级的同性能细石混凝土或自密实混凝土浇筑，严格控制坍落度及扩散度，采用微型振动棒进行振捣，同时安排专人随混凝土流淌进展部位不断敲击模板，确保混凝土不发生漏振或孔洞，并留取同条件试块，以随时掌握混凝土强度增长情况。

⑺拆模：待混凝土强度达100%后，进行模板拆除，后现场清理。

⑻强度检测验证：采用回弹仪进行现场检测，确保强度满足设计要求。

5.2柱加固

其操作工艺为：凿除清洗钻孔清孔注胶植筋固化钢筋绑扎模板支设混凝土浇筑拆模强度检测验证。具体操作方法为：

⑴凿除：用手锤、钉子凿除柱松散、过火损坏的混凝土至新鲜、坚实的混凝土基面，深度满足未碳化混凝土层深度且确保原有柱子箍筋全部外露，不得用力过猛，造成构件二次损伤。

⑵清洗：用高压水清洗混凝土表面。

⑶钻孔、注胶、植筋等：将柱子截面四边均加大100mm，按照原有柱主筋直径及间距沿增大截面后柱四周均布，用冲击钻钻孔；植筋深度以柱筋直径的15倍为宜用吹风喷嘴清孔至无尘后注胶固化，经拉拉拔检验合格后进行箍筋绑扎；箍筋直径、间距同被加固柱箍筋间距。对附墙柱应增大外露截面尺寸长边200mm、短边100mm，按照原有柱截面主筋直径间距沿增大截面均布，用冲击钻钻孔植筋，进入顶板深度以板厚的2/3为宜。

⑷钢筋绑扎：绑扎柱钢筋，规格、规格同原柱。

⑸模板支设：沿柱子周围搭设支撑架，支撑间距不大于300mm且与支撑架相连成整体；沿模板高度方向设置浇筑混凝土口共四个沿柱子侧面对称布置，宽度300mm，高度250mm。钢筋绑扎完后支设柱模板，并充分浇水湿润。

⑹混凝土浇筑：采用比原设计柱混凝土高一个强度等级的同性能细石混凝土或自密实混凝土浇筑，严格控制坍落度不小于200mm，选用微型振动棒振捣，连续浇筑不间断，确保混凝土密实。同时安排专人不断敲击模板，确保混凝土不发生漏振或孔洞，并留取同条件试块不少于3组，以掌握混凝土强度增长情况。

⑺拆模：浇筑完12h后进行模板拆除，塑料薄膜覆盖养护、专人持续养护不少于7天。

⑻强度检测验证：采用回弹仪进行现场检测，确保强度满足设计要求。

6.安全措施

6.1地下室的光线必须充足，除作业面外还有进出地下室通道的光线。

6.2加强通风效果，减低安全隐患。

6.3专人清理施工道路及作业区内的垃圾，尤其是地面上的钢筋头等，防止造成人员跌倒受伤及材料损失。

6.4安检员定期巡查，及时排除各类安全隐患。

7.结语

按照上述方法实施加固后，经检测混凝土强度以达到设计要求，效果良好。应加强现场施工管理，加大现场安全检查力度，现场动火前必须办理动火令，做到动火地点清、动火监督强、动火情况明。一旦发生火灾，应尽早进入进入现场了解情况，采取有效措施减少损失，降低因扑救不及时致火灾蔓延造成更大损失的几率。

第5篇：暑假的收获范文

“金融期货之父”梅拉梅德给中国股指期货投资者的建议是：培训培训再培训。而有中国股指期货“教科书”之称的刘仲元给投资者的建议是：学习学习再学习。

“作为金融衍生品，股指期货是非常有效的产品，但在扩大收益可能性的同时，也扩大了风险的可能性。所以在对股指期货完全了解之前，不要贸然进入到这个市场。而在进入市场之前，一定要学习学习再学习。”刘仲元一再强调“风险”两字。 　股指期货时代的到来，“做多做空都赚钱”的口号撩得人热血沸腾。股指期货推出后仅仅两周的交易，就有许多一夜暴富的新闻见诸报端。其中，在19日暴跌之下，有人因做空一日赚了三四百万元。刘仲元说：“这或许只是一个传奇，没有普遍意义。在期货业几十年里，我见过许多商品期货的炒家，从几万元一夜暴富成几亿元，没过多久又回到了几万元的老位置。为什么?因为他操作正确具有偶然性，实际上还没有真正地掌握规律。因此，股指期货开出来了，投资者千万别急于求成，千万别看到少数人的成功就眼里只有收益而没有风险。”

“风险两字是期货投资的老生常谈，但真正始终能将风险控制得很好的却少之又少。进入股指期货市场，首先要控制好风险，其次才能谈盈利。”刘仲元认为，作为股指期货的新手，尤其是那些从没有接触过商品期货的投资者，一定要切记，从一手开始做起，从少到多，从小到大，循序渐进。一定要扎扎实实走好四步曲，从理论学习开始，到模拟交易，再到小单量的实战交易，然后再开始正式的常规交易。

不要满仓不要频繁操作

“股市的波动对长期投资没有太大的影响，但期指的波动稍大一些就可能造成爆仓。因此，满仓对股市投资者可能是一种常态，但要想成为股指期货的行家里手，一定要牢记：永远不要满仓!保证金动用不要超过30％。”

此外，刘仲元建议普通投资者不要频繁操作。因为买卖期货除了进行套期保值和套利外，就是在趋势判断过程当中获取收益。但判断市场需要很高的技巧，所以刘仲元建议，不要频繁操作。他指出，投资者看好做一个趋势、做一个方向性的选择并持有一段时间比频繁操作要好，因为频繁操作就要对市场做出更多的判断，判断上涨了就要做多，判断下跌了就做空，但在期货市场上，投资者决策越多失误就会越多，就可能造成越多的损失。

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 .

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.

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！
