临界的

The transition thickness is significantly dependent on the growth temperature and germanium content, and is always smaller than the critical thickness of pseudomorphic growth.

但是，当降低生长温度时，Ge〓Si〓在Si衬底上作二维生长的临界厚度可明显增加。

The analysis indicates that the combustion of base bleed charge is in the critical zone between extinguishment and reignition when the base bleed projectile is just out of the gun muzzle.

分析表明，在火炮发射条件下，底部排气弹出膛口时，复合底排药剂燃烧环境恰好处于永久熄灭／熄灭后再复燃的临界状态。

There are two cases to define the failure. One is the rotor system can not to strit over the critical speed, and the other is arising the bistable characteristic.

并定义了两种失效的情况，一是转子系统过不了临界转速，二是出现双稳态特性。

For each specified amount of titanium tetraiodide used, there is a "critical Al/Ti ratio" at which the catalytic system displays highest activity, below which it shows no activity, and above which its activity decreases gradually Fig.

对每一四碘化钛用量出现一具有最高活性的&临界Al/Ti此&；低于这一Al/Ti比，活性完全消失；高于这一Al/Ti比则活性逐渐降低(图2)。

From this figure, a threshold for severe undercutting

从此图中可以看到，严重拉底的临界值

Gap acceptance theory is one of calculating the capacity method of unsignalized intersections. Both Critical gap and follow up time play great role in that method.

间隙接受理论是计算公路无信号交叉口通行能力的主要方法之一，临界间隙和随车时距是其中2个重要参数。

It is very importation for our country to determine the critical gap and follow up time value at unsignalized intersections in China typical region under the current road and traffic conditions.

在我国道路交通条件下，确定具有代表性的公路交叉口临界间隙和随车时距值，具有重要意义。

It provided the basis for constructing the spent fuel critical experimental facility and development studies of burnup credit technology.

本文为以后建造乏燃料临界实验装置，开展燃耗信任制技术的综合研究打下了基础。

There is beginning to be a critical mass of green roofs around the world, each one an experiment in itself.

世界各地的绿色屋顶已经开始达到临界数量，每个屋顶本身都是一个实验。

The results show that the anodic reaction is rapid and the current increases quickly and the specimen's surface is bestrewed with arc discharge when the anodic voltage exceeds 170 V.

结果表明：氧化过程存在一个明显的临界电压值(170 V)，在电压大于170 V阳极氧化反应剧烈、氧化电流增大、试样表面出现弧光放电。

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。
