The effects of FPL andits three ingredients on growth of ovary,on micro-and ultra-structure andAlkaline phosphatase activity of endometrium,on structure andkeratinization rate of exfoliated cells in vaginal epithelium in mice,onmicrocirculation in rat and on uterine kinesis in rabbit were respectivelyobserved by the techniques of light and electron microscopes,histochemistry,microcirculation and organ cinetography.The results have confirmed themechanism of FPL for the sterility caused by ovary standstill and persistentcorpus luteum to be as follows:(1) a weak estrogen-like role which canprompt development of ovary,proliferation and secretion of endometrium andvaginal epithelium and cornification of exfoliated cells in vaginal epithelium;(2)enhancing AKP's activity of endometrium;(3)improving microcirculation;(4) exciting uterus.

分别采用光学显微镜和电子显微镜技术、组织化学技术、微循环技术和器官运动描记等现代医学实验技术，观察了促孕液对小白鼠的卵巢发育、子宫内膜的显微和超微结构和碱性磷酸酶活性、阴道上皮结构和脱落细胞的角化率、对大白鼠的微循环和对家兔的子宫运动的影响，结果证实了促孕液治疗卵巢静止、持久黄体的机理：(1)微弱的雌激素样作用，能刺激卵泡发育，促进子宫内膜和阴道上皮增生、分泌和阴道上皮脱落细胞角化；(2)提高子宫内膜碱性磷酸酶的活性；(3)改善微循环；(4)促进子宫运动。

It is found that the sample stained with silver methenamine instead of mercaptoacetic acid-osmium can prevent the false phenomena caused by the inappropriate use of mercaptoacetic acid.

摘 要：本文将六亚甲四胺银染色法作为加工毛发的电子染色剂得到较好的电子显微图像，并系统地比较了用巯基乙酸-锇法染色的羊毛样品和用六亚甲四胺银染色的人发样品的超微结构，认为对深加工过的毛发样品用六亚甲四胺银法替代巯基乙酸-锇法染角蛋白，可以防止巯基乙酸使用不当引起的假象。

The ultramicroscope, the UV microscope and the luminescence microscope exemplify the inventive genius of those years and reflect three goals of microscopy, which have remained topical to date: Making ever smaller dimensions accessible to observation; observing living objects without damaging them; and finding methods to contrast the substances in such objects.

超显微镜，紫外显微镜、冷光显微镜的发明向我们展示了那个年代的天才智慧。同时也反映了显微术不断追求的三个目标：观察到更小尺度的物体；避免观察对活体的损伤；提高观察对象的图像反差。

When pea ( Pisum sativum L.,Alaska strain) was grown in short\|day conditions,the apical bud senescence started with the transformation of the bud from vegetative to reproductive growth.DNA fragmentation was detected during the senescence using the terminal deoxynucleotidyl transferase\|mediated dUTP nick end in situ labeling method.The cell ultrastructural changes were similar to apoptosis in animal cells:the apical meristemetic cells underwent the programmed cell death.This wa...

显微、超微结构研究表明，短日照条件下豌豆顶芽的衰老过程是从营养生长锥向花芽的转化，而用DNA原位末端标记、Caspase 8WesternBlot和 14 0bpDNA片断积累的试验结果证明，转化为花芽的整个生长锥细胞发生了编程性死亡，而且其最顶端部分细胞首先发生PCD ，而顶端周围的分生组织细胞逐渐分化出花芽的各部分，但顶芽最后并没有发育成为完整的花，所有细胞就都发生PCD ，从而顶芽衰老

The steel is provided with the characteristics of ultra fine grain and ultra purity, so the result has the excellent mechanical properties with combination of strength and toughness. DC flash butt welding is a kind of solid joining method with high efficiency. The micro characteristics of HAZ affect the weld joints greatly.

直流电阻闪光对焊是一种高效的固态连接方法，其焊接热影响区的显微特性对焊接接头的性能有着重要的影响，由于这种方法与熔化焊具有本质的区别，所以对超细晶粒钢的闪光对焊焊接适用性研究会有助于推进新一代钢铁材料的研究和应用开发。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
