Results:The results show that the survival rate of mammary epithelial cells were decreasing gradually with the increasing of the time of TGF-β1 treatment, and the survival rates of 24 h and 48 h groups were significantly lower than that of control group (p.05); the LDH activity of 6 h、12 h、24 h and 48 h groups were significantly higher than that of control group (p.05); the DNA degradation arisesed in 12 h, 24 h, and 48 h groups' mammary epithelial cells; the activity of Caspase-3 reach to a peak at 24 h, which was significantly higher than that of control group (p.05); the acinus of epithelial cells appears to break off and collapse with the increasing of treatment time, but the leydig structure keeps integrate;...

结果表明：1、5、10 ng/mL的TGF-β1均能抑制乳腺上皮细胞的增殖，且随浓度增加抑制作用加大，呈现剂量依赖性，其中10 ng/mL TGF-β1组与对照组差异显著（P.05）；10 ng/mL TGF-β1作用于乳腺上皮细胞24 h，随作用时间延长细胞凋亡率逐渐增加，6 h、12 h和24 h组与对照组相比差异极显著（P.01）；LDH活力也不断升高，6 h、12 h和24 h组与对照组差异显著（P.05）；DNA随 TGF-β1作用时间的延长发生不同程度降解；TGF-β1作用2 h~6 h细胞大量表达HSP70，6 h达到高峰，而后下降，2~12 h的表达量均显著高于对照组（P.05）。结论：TGF-β1可以抑制奶牛乳腺上皮细胞的增殖，具有浓度依赖性。10 ng/mLTGF-β1。。。

Abstract］ Objective To explore the effect of radiotherapy on the auxesis of Hela cell in cervix carcinoma to offer the theory elements to identify whether or not the cervix carcinoma would be treated by radiotherapy with non-routine segmentation.Methods After radiotherapy with different doses,the Hela cells changes of potential doubling time by cytometry with trypanblau coloration were analysed,and the livability of clonogenic cell at the same time was detected by clone,and the two former were combined to aralyse the changes.

目的 探讨放射对宫颈癌Hela细胞系再增殖的影响，宫颈癌是否有必要实行非常规分割放疗提供定的理论基础方法在不同剂量的放射作用下，以台盼蓝染色细胞计法分析Hela在照射后不同时间点的潜在倍增时间的变化；以克隆形成实验检测其同期克隆源性细胞存活比率，并将两者结合分析。

The results are:(1) The brightness of the specimens will decrease and the chromatism will increase with the prolongation of time of heat treatment. Compared to heat treatment in vacuum, the specimens have more color changes after heat treatment in air, with the same temperature and time of heat treatment.

该研究的结论为：(1)在相同条件下，随着处理时间的延长，试材的明度减小，色差增大；空气介质中热处理和真空中热处理相比，在处理温度和时间相同的情况下，前一种方法处理后的试材材色较深。

A set of new formulas for computing the position and time of crossover points is presented.

本文给出了一组新的计算交叉点位置和时间的公式，这组公式利用测高卫星精密重复轨道的特点，不需要从星历表中读取每个弧段在赤道上的位置及穿越赤道的时间。

The experiment is designed to determine the optimum mating time of the bitches by studying the changes of the corneous cells in the vagina of the naturally estrous bitches.

而由于良种母犬的配种费用较高，加上犬主人对提高良种母犬繁殖率的期望值较大，特别希望能帮助确定母犬的准确配种时间，以收到更好的繁殖效果，因此，有必要研究母犬排卵时间的鉴定方法。

Methods: After intranasal or intraperitoneal administration of r-HuEPO, the behavioral and electroencephalographic changes were observed in pentylenetetrazol and maximal electroshock induced seizure or electrical amygdaloid-kindled seizure of rats.

另外，大鼠经鼻给r-HuEPO后，观察对最大电休克诱导的惊厥发作级别，前肢或后肢强直性伸展时间的影响；对杏仁核电点燃后阈刺激诱导的行为等级，大发作持续时间及后放电的影响。

The set of feasible operations that allocate time optimally among the three heat conduction branches for the objective function be written in terms of the net effects and the finite-time constraint are explicitly described. The result generalizes the well-known result of Curzon and Ahlborn for the efficiency of a Carnot-like heat engine at maximum power.

描述了三个恒温热源之间一切可行的循环方式，在有限时间的约束下，根据净效果定义的目标函数对热传导分支运行时间进行了优化分配，推广了类卡诺热机在最大输出功率时Curzon和Ahlborn所得到的效率结果。

Some time after the Council of Chalcedon (451) Theodoret wrote a "Compendium of Heretical Fables" which is of considerable value for the history of Gnosticism, because it gives in a very concise and objective way the history of the heresies since the time of Simon Magus.

一段时间后，安理会卡尔西（ 451 ） Theodoret写了&简邪教寓言&，这是很大的价值的历史诺斯替主义，因为它非常简洁，客观地看待历史的歪理邪说，因为时间的西蒙贤者。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
