查询词典 turning point

It shows that the diffusion of the strip in the winding process is caused by the difference of the degree that the winding point lag s behind the guiding point.

研究表明，条带在卷绕过程中发生的扩散是由于卷绕点相对于导纱点的摩擦滞后程度的不同而引起的。

Permanent wilting point The point at which soil has dried to the extent that plants can no longer remove the remaining water held on the soil particles,and begin to wilt and will not recover,even if moved to a cool,dark place,unless more water is added to the soil.

永久萎蔫点：指土壤干旱的程度足以引起植物不再能从土壤中吸收水分，开始凋萎，即使是将其移到阴凉、黑暗的地方，也不能再次恢复，除非给土壤中添加更多的水。

The permanent wilting point is reached when the plant has wilted to a point where it will not recover, even if more water is added, because the cells have plasmolyzed.

当植物的萎蔫达到一定程度就不可以再复原，这一极限被称为永久萎蔫点。超过此极限，补充再多水分也不能被吸收，因为已经胞质浓缩已经到达质壁分离的程度。

When rabbit run the terminal point quickly, heard however to spread a burst of war whoop in the terminal point, the tortoise won again.

当兔子就快跑到终点时，却听到在终点传来了一阵欢呼声，乌龟又赢了。

By using several thousands of point vortices and small space mesh, we obtain the large scale discrete vortices on the vortex sheet as result of the pairing of small point vortices, thus simulate the instability phenomena of the rolling-up vortex sheet.

由于使用了数千个点涡和较小的空间网格，获得了前缘涡层小涡配对出现的较大的离散涡，模拟了紧卷涡层的不稳定现象。

E Vibration and temperature point can be set up, the instrument will report to the police with sound and light when exceeding the warning point.

e 振动和温度报警点可设置，当出现超过报警点时仪器用声光报警。

In the present work, based on the mechanism of low - temperature corrosion, an opinion was presented by theoretical analysis and computation, that is the vacuum boiler can not avoid being corroded completely under low temperature, but the corrosion is very weak no matter if the exhaust gas temperature is higher than the flue gas dew point; it was obtained the relationship between the corrosion velocity of metal wall and wall temperature along gas pass of vacuum boiler, and the one between the corrosion velocity of metal wall and wall temperature under the condition that the flue gas temperature is lower than the acid dew point.

文章从锅炉发生低温腐蚀的机理人手，通过理论分析计算并通过实践检验，提出了真空相变锅炉虽然不能完全避免低温腐蚀问题，但不论排烟温度是否高于烟气露点，低温腐蚀的程度都很弱的观点；给出了真空相变锅炉沿烟气流程金属壁面的腐蚀速度与壁面温度的关系曲线，和烟气温度低于酸露点时金属壁面的腐蚀速度与壁面温度的关系曲线；同时，文章推荐真空相变锅炉的设计排烟温度取130℃左右的低排烟温度。

本文从锅炉发生低温腐蚀的机理入手，通过理论分析计算并通过实践检验，提出了真空相变锅炉虽然不能完全避免低温腐蚀问题，但不论排烟温度是否高于烟气露点，低温腐蚀的程度都很弱的观点；给出了真空相变锅炉沿烟气流程金属壁面的腐蚀速度与壁面温度的关系曲线，和烟气温度低于酸露点时金属壁面的腐蚀速度与壁面温度的关系曲线；笔者专门从事真空相变锅炉的设计研究已十多年，根据上述观点设计的数百台产品已经过多年实际运行，未发现明显低温腐蚀。

The essential point is to consider the response of the two-point correlation

其要点是考虑两点关联函数在一个弱的固定外场作用下的响应。

His final shot knocked his two-point rock to the very edge of the three-point zone.

他的最后一击把他两分的石刚好打到三分线的边缘。

You can do some assertiveness training.

你可以进行一些自信训练。
