By dilatometric change and microscopic test, the critical point at Ac1、Ar1、Ac3 and Ar3 of ML40Cr steel was detemined in Gleeble-3800 the thermal-mechanical simulator. The continuous cooling transformation diagram of ML40Cr steel was obtained by measuring the expanding curves of different cooling rates. The mechanical property and transformation of austenite were analyzed. The proper range of control cooling rate about ML40Cr cold heading steel was found. All those provide the reference for productive practice to develop cold heading steel.

The results show that the modificator Mg can cause thermodynamic undercooling , and it may absorb in the crystal faces of preferential growth of carbides, which can slow down carbides growing up on plate type and make them tend to be fine, isolated and passivated, and thus the impact toughness is improved greatly.

研究结果表明：在过共晶高铬白口铸铁结晶过程中，变质元素Mg不仅造成热力学过冷，而且Mg可能吸附于碳化物择优长大的晶面上，起到阻碍碳化物片状长大的作用，使碳化物趋于细小、孤立，且边部钝化，使冲击韧度显著提高。

The directional solidification under negative temperature gradient with unstrained cooling and superrefined directional microstructure are observed.

并在△T〓≤△T＜△T〓过冷度区间完成了无外界冷速约束的负温度梯度下的定向凝固，获得了快速凝固条件下的超细定向组织。

Marriages fail, however, not simply because of the outside weather but because the inner climate becomes too hot or too cold, too turbulent or too stupefying.

但婚姻失败并不是简单地由外部天气造成的，而是由于内部气候变得过热或过冷，变得过于狂暴或过于麻木造成的。

Before conducting the study, students believed that Heat could not influence gas and liquid volume.Matter didn't have thermal expansion. Metal ring's diameter will shrink after heating. The melting quantity of salt is much quicker and faster than sugar in the same temperature or water. Only metals can conduct heat, but not wood, glass, plastics. The quantity of heat is by steam way disappearing.

一、学童对「物质与热」的迷思概念有：(1)「热对气体、液体体积不会有影响」的概念，(2)听过热胀冷缩的语词，但是对原因不明了，(3)金属双圆环加热后，内环孔的口径会变小，(4)同温度且等量水，盐的溶解量比糖多、也比糖快；(5)木材、塑胶、玻璃不会传热，金属才会传热；(6)以为热量是以水蒸气方式散失，(7)冷气机应安装在高处，冷房效果较佳；(8)误认为金属是良好的保温材质。

An electronic Hydraulic driving fan cooling system was designed to solve the problem of overheating and overcooling in the construction machinery.

开发了一种电控液驱风扇冷却系统，解决了工程机械的过热和过冷问题。

Japan has studied the dynamic ice Making and storage system for more than 10 years, and made great amounts of research work.

对冰晶成核理论的研究和过冷水过冷度的影响因素的研究，是设计该连续制冰系统稳定工作的基础，其中过冷却器的设计尤为关键。

The altostratus base is 2 km high, and cloud top is higher than 5 km. The supercooled water exists abundantly in the cloud, the maximum is up to 0.21 g.m-3 at -11.20℃, but its distribution is not homogeneous, 87%of continuous distribution width are less than 2.4 km, which is disadvantage to the rime increasing of ice crystal in the cloud. Meanwhile, the evaporation effect of subcloud raindrop is very big, the diameter of raindrops which could not arrive the ground is less than 1 mm. Therefore, The cold vortex process produces the weak precipitation.

As云底高2 km，云顶高大于5 km，云中存在比较大的过冷水区，-11.2℃时的过冷水含量0.21 g.m-3，但过冷水的含量分布极不均匀，大于0.05 g.m-3的过冷水区连续分布的宽度87%小于2.4 km，不利于云中冰晶的连续凇附增长；同时云下雨滴的蒸发效应大，直径小于1.0 mm的雨滴难以落到地面，因此本次过程只产生弱的降水。
