使冷却

The ice/liquid mixtures of the coolant and the sample solution were respectively added in the Dewar bottle and the sample container to precool for 2~3 hours under stirring. Then some of the coolant liquid was replaced with coolant ice, the motor stirrer was restarted, and the temperatures were read from the Beckmann thermometer.

实验时，先调节寒剂的组成使其凝固点低于待测溶液的凝固点～2℃，然后分别在保温瓶和凝固点杯中加入寒剂和待测溶液的冰水，启动搅拌器预冷却2~3小时，接着更换保温瓶中的寒剂冰水，重新启动搅拌器，记录贝克曼温度计读数。

A model describing the relationship between recovery stress and temperature is developed based on the modified Clausius-Clapeyron equation. A composite model based on the Tanaka model is used to calculate the thermal expansion strain of composite, and the relationship between the martensitic fraction and temperature. Results show that this relationship is nonlinear, affected by prestrain and the heating-cooling history.

利用Tanaka模型以及在Tanaka模型基础上所建立的复合材料的模型，分析了TiNi合金丝/Al基复合材料的热收缩应变，以及复合材料中TiNi合金丝发生逆相变过程中马氏体分数与温度的关系，结果表明马氏体分数与温度之间的关系并非近似线性，而是随着预应变的不同、加热冷却过程的不同而变化的，在具体的使用时应根据不同的情况具体分析。

However, it develops that the rate of cool in g dur in g the expansion in any practical nozzle is too fast for the recomb in ation to occur.

然而，实际情况是，然后实际喷管里气流膨胀时冷却速度都很快，使分子来不及重新化合。

The molten end parts then fuse, and the molten joint is then cooled to resolidify the material and form the joint.

然后将熔化的端部融合在一起，再将熔融的接头冷却，使材料重新固化并形成接头。

New units have a raised, slatted floor design whereby air for cooling is drawn up through the slats.

新单位有一个提高，板条地板设计，使空气冷却是通过制定板条。

Achieving through the above sufficient nascent grains that they grow spheroidally on subsequent cooling.

通过以上过程形成足够多的初始颗粒，再经过接下来的冷却。使他们以球形增长。

The experiments show that too high cooling rate disadvantages the formation of spherical primary crystals, while higher mechanical stirring strength is necessary to spheroidize and homogenize the primary crystals.

较高的搅拌强度可以有效地减小初晶硅的尺寸，并使之边角钝化和均匀化；但当冷却速率太大时，由于搅拌时间缩短，则不利于球形初生相颗粒的生成。

It is necessary for two kinds of controlled cooling processing to possess air cooling phase to separate ferrite from austenite, and, by means of this, polygonal ferrite forms, the carbon concentration of the retained austenite untransformed increases and results in the stability of retained austenite increased.

在二种冷却方式轧后控冷的过程中，必须有一个α/γ二相分离的空冷阶段，使多边形铁素体形成，未相变奥氏体中碳浓度增高，其稳定性增强。

The yarn is twisted, exposed to heat which sets the twist in place, cooled and untwisted.

长丝首先被加捻，再被加热，在加热时使捻度定型；然后冷却，最后除去捻度。

The yarn is twisted, expose d to heat which sets the twist in place, cooled and untwisted.

长丝首先被加捻，再被加热，在加热时使捻度定型；然后冷却，最后除去捻度。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
