At the same time it is shown the population dissociation coefficient method is abetter calculating method for structural reliability in solid rocket motors and themajor factor affecting structural strength reliability is the standard deviation.

在置信度为0.90时，其结构可靠度大于0.9954。同时表明总体变异系数法是较佳方法，影响结构可靠性的主要因素是样本标准差。

The effects of strain rate on plastic formation and dynamic recrystallization of 7050 aluminum alloy were discussed. The results show that the deformation of the specimen is inhomogeneous, and the effective strain in the center of the specimen is maximum. The deformation inhomogeneity increases with the increase of strain rate. The effective stress of specimen is inhomogeneous. As the strain rate increases, the minimum stress value moves from the drum-shaped region to the heart of specimen. The standard deviation of dynamic recrystallization grain size decreases with the increase of strain rate.

模拟结果表明，热变形过程中，试样的各个部位的变形分布不均匀，心部的等效应变最大，变形的不均匀性随应变速率的增大而增大，但是变化的程度不大；试样内部各部位的应力大小分布不均匀，随应变速率的增大，最小应力值由自由变形的鼓形区域逐步向心部移动；动态再结晶晶粒尺寸标准偏差随应变速率的增加而减小。

Results The linearity of this method was good, the linear range for curcumine was 2.675~53.500 μg/mL (r=0.9999), the average recovery of curcumine was 99.78%, relative standard deviation was 0.59%.

结果 姜黄素在2.675~53.500μg/mL浓度范围内呈良好的线性关系（相关系数r=0.9999），平均回收率为99.78%，相对标准偏差为0.59%。

My baby was 2 weeks premature Caesarean section birth, insufficient breast milk, a month-An artificial feeding infant formula, has been eating better, although not a lot of food, but feed feeding table on the small standard deviation. 3 months have been all-you-can-per-150ML (a daily 5 times), but from 100 days to go to work I started on the point of death, my mother fed her the first time when the spit after eating 160ml, From then on, she ate 1 milk cried, but also fewer, and sometimes even a day 600ml are not, I work to feed her a little better, so that lasted about 10 days, my mother fed her不哭, and a 150ML, half an hour or so, I and she was dying husband to feed, each drink 60ml always to哭一场, tired of crying sleep eat eat 100ML, before and after one hour, the key is always eaten吐奶, four hours after the infants When she was always not interested, do not care to eat do not eat at all, thought it was tired of the beginning of milk, or poor appetite, but now has lasted more than a month, or about 700ml a day, nothing else very good, playing love laugh, urine are normal, sleep, or how to do?

我的孩子是早产2周剖腹出生，母乳不足，1个月开始人工喂养安婴儿奶粉，一直吃的还好，虽然吃的不是很多，但和喂哺表上的标准差的不多。3个月时已经吃到每次150ML(每日5次)，可是从100天后我上班开始就不行了，我母亲给她喂第一次时160ML吃完后吐了，从此以后，她一吃奶就哭，而且量也少多了，有时一天连600ML都没有，我下班喂她稍微能好些，这样持续了十天左右，我母亲喂她不哭了，一次150ML，半小时左右，我和老公喂她却不行了，每次喝到60ML时总要哭一场，哭累了睡着吃再吃100ML，前后要一小时，关键是这样吃完总是吐奶，四小时后该吃奶时她总是没兴趣，一点都不在意吃不吃，开始以为是厌奶，或是胃口不好，可现在已经持续一个多月了，还是一天700ML左右，其他什么都很好，爱玩爱笑，大小便都正常，睡觉也好，怎么办？

First of all two-dimensional bar code of the positioning and segmentation algorithm using Hough Transform and Sobel edge detection of the bar code images collected from the original image to effectively separate and then analyzes the barcode image through the optical system of the noise model, put forward a Calculation of point spread function of standard deviation of the algorithm uses Flourier transform adaptively select the threshold to remove noise caused by invalid border, bar code and thus be the basic module.
