半衰期

We close this tests series with Half Life 2 tested here with functions filtering and anti-aliasing.

我们结束这一系列的测试，半衰期2测试此功能过滤和反锯齿。

With or without antialiasing, the hierarchy of our cards remains identical under Half-Life 2 Lost Coast.

或无抗锯齿，层次，我们仍然卡完全相同下半衰期2半条命。

However, because of its short half-life in vivo and antigenicity, its medical efficacy was reduced greatly.

然而由于该酶体内半衰期短且易引发免疫反应而降低了该酶的临床应用效果。

The appearance of-enantiomer after incubation with single-enantiomer revealed the enantiomeric inversion of-isomer to its antipode. While no obvious stereoselective degradation or enantiomeric inversion were observed in other test soils.

左右旋对映体在3~#土壤中的降解速率有明显差异，二者半衰期相差0.95周；添加外消旋体培养6周后ER值达到1.65，表明左旋体被优先降解；同时在该土壤中存在左旋体向右旋体的转化现象；在其他几个土壤中均未有明显的选择性降解或对映体转化现象。

The mechanical properties and static half-life of blend fiber were decreased with the addition of the composite antistatic agent.

共混纤维力学性能和静电半衰期随复合抗静电剂含量的增加而减小，含PEG20000的共混纤维抗静电效果更好。

Results Half-life( t1/2) of PDDZ degradation in 20% rabbit plasma was 210 min and the parent drug AZT was the degradation product.

在不同流动相条件下测定齐多夫定和PDDZ的含量。结果 PDDZ在体积分数为20%的家兔血浆中的降解半衰期为210 min，降解产物为AZT。

Beta decay half-lives are a few milliseconds or more.

衰变的半衰期为几个毫秒或更长。

Bismuth -213 choice because it has several characteristics, including the half-life of 46 minutes.

选择铋-213是因为它有几种特性，包括半衰期为46分钟。

No, Chloral Hydrate has a half-life of only 4 hours in people with a high tolerance.

不是，对"水合三氯乙醛"有较高耐药能力的人，它的半衰期仅为4个小时。

Methods Activated partial thromboplastin time were determined by coagulometer for rabbit blood samples collected before and after i. v. rH. Based on the dose-and time-effect relationship of rH, the elimination kinetic model of nil anticoagulant activity was ascertained. And t1/2 was calculated.

家兔i。 v。 rH前及后采血，用血凝仪测定活化的部分凝血活酶时间，基于其量效关系和时效关系，确定rH抗凝活性消除动力学类型，并计算抗凝活性生物半衰期t1/2

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
