It was illuminated that the width of the centre bright fringe decreased along with the increasing width of the rectangular aperture when the effect of the aperture on the beam couldn't be ignored,however,the width of centre bright fringe step changed with increase of the size of the aperture when the effect could be ignorable,the width of the half maximum intensity of the centre bright fringe decreased along with the accretion of the width of the aperture and then it tends to a constant.

结果表明，当光阑对光束的衍射影响明显时，光束衍射场的中央亮条纹的宽度随着光阑边长的增大而减小；当光阑对光束的衍射影响极小时，中央亮条纹的宽度随着光阑边长的增加而阶跃变化，中央亮条纹强度的半最大值宽度随着光阑边长的增大而减小；当光阑对光束衍射影响极小时，中央亮条纹半最大值宽度趋近于一定值。

The least they can buy is 1/16 for 50 hours a year, and the most, half a plane for 400 hours.

Westinghouse Prizewinner John Kuo recalls that in Taiwan he was accustomed to studying two or three hours a night."Here we had half an hour at the most."

I watched her for nearly half an hour: during all that time she never turned a page, and her face grew momently darker, more dissatisfied, and more sourly expressive of disappointment.

我观察了她近半个小时，这半个小时内她没有翻过一页书。她的脸色一瞬间变得更阴沉、更不满，更加愤怒地流露出失望的心情来。

24H treatment group compared with 24h model group: the density of light of HSP70 of the group increased and which of TGF-β〓, is not different with the model group; the density of the light the HSP70 of the Baicalin group increased and which of it the TGF-β〓, increased with the model group; the density of light of the Concha Margatitifera Usta is not different and which of TGF-β〓, increased with the model group; the density of light of the Cholic Acid group is not different and the density of light of it of TGF-β〓 increased with the model group; the density of light of the Hefang Group is not different and which of TGF-β〓 is not different than the model group.

合方治疗脑缺血12小时组缺血脑组织TGF-β1光密度值较缺血12小时模型组无显著性差异（p＞0.05）。本实验结果发现，与单纯缺血12小时、24小时大鼠相比，药物干预组缺血侧大脑皮层TGF-β1免疫反应明显增强，计算机辅助图像半定量分析两组间缺血侧大脑皮层TGF-β1免疫阳性细胞数差异非常显著。说明药物对局灶性脑缺血损伤可能有一定保护作用，其机制可能与诱导脑细胞TGF-β1合成增加有关。然而，药物调控TGF-β1表达，其促TGF-β1表达增强的机制可能是这样的：脑缺血时TGF-β1mRNA表达增加可能与缺氧诱导神经和胶质细胞刺激生长因子表达有关。

My daughter next month on the two-year-old half, two hours before going to bed every night to drink 210 milliliters of milk formula, but always at night urine II ~ IV back urine, adults are fatigue , she can not sleep free from anxiety, she did not do during the day, who can tell me how to let her oliguria night?

两岁半的孩子晚上还尿床怎么办？我女儿下个月就两岁半了，每晚睡觉之前两小时喝210毫升配方奶，但是夜间总要尿二~四回尿，大人很疲劳，她也睡不塌实，白天她不这样，谁能告诉我怎样才能让她夜间少尿？

Preparation and exosyndrome of liposomal Gd-DTPA 1.1 Preparation small unilamellar vesicles were prepared by combining 0.92 g of distearoylphosphatidylcholinc with 23 mL of distilled watcr.

Gd-DTPA脂质体的制备和表征 1.1制备工艺精密称取一定量二硬脂酰磷脂酰胆碱乙醇胺溶于双蒸水中，置于恒温磁力搅拌器内，在69～72℃恒温条件下超声分散1小时，取一定量Gd-DTPA溶液、蒸馏水和无水乙醇与上述产物混合，获得半透明胶体状物，在室温下过夜，第二天在69～72℃恒温条件下水浴孵化1小时，同时用低流速氮气吹拂液体表面除去有机溶剂无水乙醇。

The closest period of time everyday the snapshot circumstance of the website, website already a few months Baidu from collect experienced 10 days now half month updates snapshot to arrive 24 hours to update again to a week, update a few pages to update several much pages to from, arrive 24 hours from 24 hours of a few pages the snapshot of 200 much pages, this paragraph of time understands eventually, to Baidu snapshot should update ability 24 hours to be have weight, baidu did not use PR value to measure the weight of a website like Gu Ge, what does that use, I feel to return is the time that snapshot updates, the jump overing that a website updates in 24 hours has weight more more, because do not think what giving just is Baidu weight really, cannot use PR to see, of course this is pure belong to an individual close a point.

最近一段时间每天网站的快照情况，网站已经几个月了百度从收录到现在经历了十天半个月更新一次快照到一个星期再到24小时更新，从一次更新几页到一次更新数多页，从24小时几页到24小时200多页的快照，这段时间终于明白，对百度来说快照要24小时更新才算是有权重，百度没有像谷歌一样用PR值来衡量一个网站的权重，那用什么呢，我觉得还是快照更新的时间，一个网站在24小时更新的越多就越有权重，因为实在想不出什么才是百度权重，不能用PR一下看出来，当然这纯属个人的关点。
