下降

Two weeks after injection of putrescine,the activity of OTA in normal rats was decreased, followed by an increase and then returned to normal.

正常大鼠注射腐胺后，肝内鸟氨酸转氨酶活性呈相双变化：二周后下降约50％，以后又上升，至第八周达最高峰，约为对照组的180％，随后又下降。

Treatments with 20μmolL^(-1) CoCl2 and 20μmolL^(-1) AVG did not influence the contents of putrescine, spemidine, spermine, chlorophyll, and the production rate of reactive oxygen species. However, after 12h heat stress of 45℃, treatments significantly promoted the above values.

但经45℃高温胁迫12h后，20μmolL^(-1) CoCl2与20μmolL^(-1) AVG溶液处理显著提高了上述3种多胺的含量，减缓了抗氧化酶活性的下降，对活性氧水平及脂质过氧化水平的增加也起到了有效的抑制作用，这些改变可能对叶绿素降解的减少及膜稳定指数下降的减轻发挥着重要的作用。

Thus, user does not know quantity of electricity of battery.

在目前的有源射频识别系统中，随着使用时间的延长，电池的电量下降，使得自动识别系统的作用距离下降。

In the case of racemate 2, better resolution was obtained when using 2-propanol as modifier in the place of methanol and ethanol, while for racemate 1, methanol provided the best performance. Both retention and resolution decreased with increase in pressure.

结果表明对映体的保留因子均随着改性剂含量的增加而显著下降，当改性剂含量大于10%时，保留因子的下降趋势变缓；分离帕罗酮酯时，异丙醇作改性剂的分离度和分离因子均最大，分离帕罗醇对映体时，甲醇是最佳的改性剂。

The contents of galactose, glucose, fructose, sucrose and raffinose of seed were tested. The results showed the galactose content of seed increase as the storage temperature increases. However, the glucose, fructose, sucrose and raffinose content of seed decrease as the storage temperature increases.

通过对半乳糖、葡萄糖、果糖、蔗糖和密三糖含量的研究，结果表明，随着贮存温度的升高，种子中半乳糖的含量不断升高，随着含水量的降低，种子中半乳糖的含量逐渐降低，且随着贮存温度的下降，种子中半乳糖含量随种子含水量下降而降低的趋势减缓。

Rappel/ abseil stations should be installed where descending by foot is likely to cause erosion problems.

3下降点的设置处，应选在以步行方式下降会产生侵蚀问题的地点。

Once up on top, be careful the euphoria of the summit doesn't get in the way of precautions for the rappel down.

只要你上攀便须要下降；登顶之后，小心登顶的陶醉而忽略了安全的下降。

The problem is not in readership decline, it seems, but in teen readership decline.

问题并不在于在读者的下降，似乎，但在青少年读者的下降。

The experimental results show that the recognizability could be used as a measurement determines whether we will perform face recognition or not.

实验的部份，测试可辨识度和实际辨识率之间的关系。实验结果发现辨识率在可辨识度下降的情况，也会跟著下降。这代表我们所提出的可辨识度能够有效提供辨识系统一个辨识度的参考。

E.g. Between 1986 and 1987, Nike's sales dropped 18 percent and profits sank by more than 40 percent as a result of competition with Reebok.

与"锐步"鞋业竞争的结果，从1986到1987年，耐克的销售额下降了18%，利润下降了40%多。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
