Methods According to the oestradiol level on progesterone initiation day, 279 hormone replacement-frozen embryo transfer cycles were grouped into three groups group 1, percentile 0-25(superscript th; group 2, percentile 26-75; group 3, percentile 76-100.

按照激素替代－冻融胚胎移植患者黄体酮开始注射日血清雌二醇质量浓度的百分位数，将279个周期进行分组（组1百分位数为0~25，组2为26~75，组3为76~100）。

The concentration of progesterone(P4 ),17β-oestradiol (E 2 )and luteining hormonein the peripheral serum of white Xiang pigs was measured by radioimmunoassaythroughout the whole oestrous cycle.

用放射免疫分析法测定了10头白香猪发情周期外周血清孕酮(P4)、17β-雌二醇(E2)和促黄体素含量的变化。

The changing trend of progesterone during oestrous cycle resembles with that during the first 14d of early pregnancy. Its content reaches the peak value at lOd after oestrus and then declines. The estradiol peak appears at 3d of oestrous cycle, and the level rises again before oestrus. The concentration of LH declines after oestrus. The level of follicle stimulating hormone reaches the peak value at lOd after oestrus (2.40mIU/ml).

发情周期：民猪发情周期孕酮的含量与妊娠早期14天内的变化极其相似，在发情后第10天达峰值，而后开始下降；雌二醇水平在发情后第3天出现高峰，下次发情前开始升高；促黄体素在发情当天达最高水平，然后开始下降；促卵泡素在发情后的第10天达到峰值(2.40mIU/ml)。

METHODS: the supernatants of cultured spleen's lymphocytes induced by ConA were injected into mice peritoneally,kinetics of plasma corticotropin releasing hormone,adrenocorticotropic hormone and corticosterone in mice were tested at different time (0.5,1,2,4,6 h),or tissue of hypothalamus pituitarium or adrenal was stimulated with supernatants induced by ConA,and the secretion of CRH, ACTH and CORT were observed.

采用ConA诱导淋巴细胞培养上清液给小鼠腹腔注射，测定不同时间(0.5，1，2，4，6 h)的小鼠血浆中CRH，ACTH，皮质酮产生的动力学，同时在体外用ConA诱导上清液分别与下丘脑，垂体，肾上腺组织共同培养后观察CRH，ACTH，CORT分泌情况。

Nevertheless, the yield of pinacol was also strongly affected by the steric environment surrounding the carbonyl group. The pinacol coupling of aromatic aldehydes has been achieved with high yields under such a condition. However, the diastereose-lectivities of pinacols were not satisfying. Unfortunately, the ketones and most aliphatic aldehydes appeared inert under the same reaction conditions.

然而， 呐偶合反应的产率受到羰基周围环境的立体位阻影响较大，在此条件下，锌粉能有效地促进芳香族醛类化合物进行水相呐偶合反应，得到的呐醇产率高，但非对映异构体选择性差，而脂肪族醛类化合物得到的呐醇产率较低，在同样的条件下，酮类化合物不能顺利进行呐偶合反应。

During the GnRHa/chemotherapy cotreatment the concentrations of FSH, LH, and P decreased to almost prepubertal levels.

在促性腺激素释放激素激动剂/化疗联合治疗期间，卵泡刺激素、黄体生成素和孕酮的浓度几乎下降至青春期前的水平。

A progestational hormone,C20H26O2,similar in effect to progesterone,used especially in oral contraceptive s.

炔诺酮合成的避孕激素，C20H26O2，类似黄体酮的药效，尤其用作口服避孕药

A progestational hormone, C20H26O2, similar in effect to progesterone, used especially in oral contraceptives.

炔诺酮合成的避孕激素，c20h26o2，类似黄体酮的药效，尤其用作口服避孕药

Progestational agents.

假孕疗法在抑制FSH和LH和子宫内膜组织上，黄体酮和口服避孕药的作用相似。

The content of intermediates such as protochlorophyll,Mg protoporphyrinand protoporphyrin IXwere reduced and δ aminolevulinc acid and porphohilinogenwere markedly accumulated in albino seedlings of W1,which proved that there was a blockage in the formation of uroporphyrinogen or coproporphyrinogen during Chl biosynthesis under lower temperature.

白化苗中Chl生物合成的中间产物原叶绿素、镁原卟啉、原卟啉IX含量减少，而δ氨基酮戊酸和胆色素原大量积累，证明突变体W1低温下Chl生物合成卟啉原形成部位受阻

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
