The quality changes of pakchoi in cold storage with vacuum cooling and air cooling, at 2℃ for 7 days, 10 days, 14 days, 19 days and 29 days were studied.

摘 要 试验研究了小白菜采后真空冷却和空气冷却后，在2℃条件下冷藏7天、10天、14天、19天和29天的品质变化。

Methods: The fetuses of interfamily pregnancy day 4, day 8 and day 12 were acted as experimental group, while the ones of intraspecific pregnancy day 4, day 8 and day 12 of embryo transfer and the uteri of pseudopregnant mice of corresponding time were employed as positive and negative groups respectively.

以科间妊娠第4天、第8天、第12天的孕体为实验组，小鼠同种移植妊娠第4天、第8天、第12天的子宫孕体和相应时间假孕小鼠的子宫为阳性和阴性对照。

There was a low level of basigin mRNA expression in the luminal epithelium on days 1 to 8 of pseudopregnancy and glandular epithelium on days 2 to 6 of pseudopregnancy.

Basigin mRNA在假孕大鼠子宫第1-8天腔上皮及第2-6天腺上皮持续表达，而basigin蛋白质则在假孕第1-2天的腔上皮及第2-6天腺上皮表达。

There were significant differences in theproliferation activity day 8 and day 10 compared with that of day 5 and day 14 inculture.

细胞生长曲线呈&S&形，8天和10天的增殖活性强于5天和14天。

The results indicated that there were four intervals of 180, 365, 545 and 730 days between ID and IM PHKCV,the sero conversion rates were...

结果表明：ID非浓缩PHKCV0.1mL后间隔180天、365天、545天和730天再肌注浓缩PHKCV，于首剂肌注后第7天、14天和30天的抗体阳性率分别为96.55％、100％、100％；76.67％、100％、100％；75.86％、100％、100％；75％、100％、100％。

A Day in the Life 一天的工作 As your bad interview lumbers on, don't wait until your interviewer asks you if you have any questions.

当一次糟糕的面试尴尬地进行时，不要等面试者来问你有没有问题要问。

It was shown that: 1 MMP2 activity reached the highest level during proestrus, and was lowest during diestrus; 2 MM2 acti vity was increased from the first day of pregnancy, peaked on day 4 of pregnancy; but decreased significantly at day 7 of the pregnancy. 3 MMP2 activity was obviously higher on day 1 of pseudopregnancy than on the other days, and its activity decreased gradually, reached the very low level at day 4 of pseudopregnancy and maintained the low level until day 7; 4 MMP2 activity was decreased significantly 24 hours after injection of 17βestradiol ( 01 mg) at metaestrus, while MMP2 activity had no change after progesterone (04 mg) injection.

明胶酶A活性变化如下：1在大鼠的动情前期明胶酶A的活性最高，间情期最低；2在妊娠早期(1～7天)的卵巢中，明胶酶A的活性在妊娠第4天达到最高，第1～3天及第5、6天其活性也较高，但第7天则明显下降；3在假孕(1～7天)大鼠的卵巢中，明胶酶A的活性在假孕第1天最高，第2、3天略下降，从第4天到第7天，其活性都处于较低水平；4动情后期大鼠皮下注射雌二醇(0.1mg/只)24小时后，明胶酶A活性明显上升。

The results show:① The predominant period bands represented in the lowfrequency fluctuation field are interseasonal fluctuations of 6 pentads (30 days) and 10 pentads (50 days) and the intraseasonal fluctuations of 15 to 17 pentads (75 to 85 days).② The 30day fluctuation period is an intrinsic fluctuation of the pentad precipitation in rainy season of Yunnan Province.③ When El Nino or La Nina happens, there is a 50day fluctuation period in the pentad precipitation in rainy season of Yunnan.④ While there is a 75-85 day fluctuation period in the pentad precipitation in rainy season of Yunnan, the precipitation anomaly percentage in the main flood period in Yunnan is positive; on the contrary, while there is no 75-85 day fluctuation, the precipitation anomaly percentage is negative.

结果表明：①云南地区雨季降水主要低频振荡周期为6候(30天)，10候(50天)的月际振荡和15～17候(75～85天)的季节内振荡；②云南雨季的候降水每年都存在30天振荡周期，30天振荡是云南雨季固有的振荡；③当发生El Nino或La Nina异常气候事件时，云南雨季的候降水存在50天振荡周期；④当云南雨季存在75～85天振荡时，云南主汛期(6～8月)降水距平百分率为正(除2000年为零距平)；当云南雨季不存在75～85天振荡时，云南主汛期降水距平百分率为负。

I'm always looking at n-day trajectories - 10, 20, 40, up to maybe 280 days. Twenty-day trajectories worked for a while, but that started going downhill 15 years ago.

我总是看N天的轨线——10天、20天、40天，一直到280天。20天的轨线有时候有用，但是从15年前开始就走下坡路了。
