Nd and Y showed more evident effects than Gd and La due to lower temperature of eutectic reaction with aluminum. In order to investigate mechanism of the formation of the intercellular dispersoid which is being in debate and possibility of suppressing the dispersoid, a nucleation kinetic model which including unsteady nucleation and effect of alloy element was established.

Al-Fe-Mo-Si-Zr-Ti合金粉末具有四种凝固组织，初生Al〓〓，α-Al与Al〓共晶，胞晶及显微胞晶，合金元素Mo的加入，显著提高合金粉末凝固前的过冷度，使10~40μm粉末的凝固机制发生了变化，由导热控制型转变成溶质扩散控制型，从而基本上消除了该尺寸范围内粉末凝固组织中共晶成分和初生相，但对大于40μm的粉末，因共晶区富Zr核心的优先形成而使Mo的作用效果不明显。

Thus the heat - exchange effect can be enhanced and the manufacture cost of equipment can be reduced.

较好解决了2种热交换介质因导热系数不同而导致的热交换不平衡和设备体积庞大、消耗钢材偏高的问题，从而有效地提高了换热器的换热效果，降低了设备的制造成本。

As a new material with many functions: being light, heat insulation, bearing acid and alkali, non-toxic, incombustible, not having fetid odor, the floating bead of pulverize coal ash was firstly chosen to produce light preservation material. In the article, a suitable production way and a new method of using pulverize coal ash systematically were found, which had active effect on stove industry and the refractoriness of light preservation brick with floating bead is 1100~1300℃, the suitable temperature was 400~1150℃, thermal conductivity is 0.105~0.127W.

粉煤灰漂珠作为一种新兴多功能材料，由于它具有轻质、绝热、耐酸碱、无毒、不燃烧、无臭味等特点，将之用作生产轻质保温材料首选材料，并探索出一条合理的生产工艺路线，为粉煤灰的综合利用开辟了一条新途径，对窑炉工业的发展将产生积极的推动作用；生产的轻型漂珠保温砖的耐火度为1100~1300℃，最佳使用温度为400~1150℃，导热系数为0.105~0.127W。

From the results the author thought that due to the lack of high quality insulator with high heat conductivity.

经分析认为，由于缺乏高性能的导热绝缘材料，目前所制作的空心阴极的冷却效果不是很好。

The calculation indicates that the influences of the heating and conduction in the beryllium reflector, aluminium and graphite components, and the ununiform heating of the fuel elements are negligible to the temperature difference between the inlet and the outlet in the core.

通过计算表明了铍块、石墨瓦和铝瓦的发热与导热、以及燃料元件发热的不均匀性对堆芯进、出口温差的影响可以忽略。

Since the company has been paying attention to the product quality, the company by "is striving for the survival by the quality, strives for the development by the prestige, manages increases the benefit, take serves makes the backing " as the enterprise objective, makes every effort into the most specialized horizontal-type sterilization pot Manufacturer.under is the horizontal-type sterilization pot's use:because the compressed air is the poor conductor of heat, the situation steam itself also has certain pressure, therefore, in sterilization time elevates temperature in the process, does not admit the compressed air, but sterilizes the pot only after meeting the thermal death point when is in the heat preservation, only then opens the compressed air to enter in the pot, makes in the sterilization pot to increase 0.15~0.2Mpa.

公司一直以来都在关注着产品的质量，公司以&以质量求生存，以信誉求发展，以管理增效益，以服务做后盾&为企业宗旨，力求成为过内最专业的卧式灭菌锅生产厂家。卧式杀菌锅由于压缩空气是不良导热体，况蒸汽本身又具有一定的压力，因此，在杀菌时升温过程中，不放进压缩空气，而杀菌锅只在遇到杀菌温度后处于保温时，才开放压缩空气入锅内，使杀菌锅内增加0.15～0.2Mpa。

Tungsten wire is made by the process of sintered bar, swaging and drawing. Besides its high temperature stability, sagging free, shock resistance and corrosion resistance, it has an excellent electrical and thermal conductivity, a very low thermal expansion up to the highest temperature.

钨丝是由钨坯条经过旋锻及拉伸的方法加工而成的，具有很好的耐高温性能和不下垂性，导电导热性能极好，热膨胀率低，成型性好、稳定性高、耐震性及抗腐蚀性强，具有较好的机械加工性能。

Therefore choose the installation location of heat-conducting oil pump, the pump cover to bearing the heat and easy to spread without any regenerative phenomenon.

因此选择导热油泵的安装位置时，要使泵盖和轴承座的热量便于扩散，不出现任何蓄热现象。

Therefore, in order to guarantee the stability of production, but also to reduce the actual running costs, heat-conducting oil bellows system should be chosen cut-off valve can not be selected filler valve seal or valve.

因此，为了保证生产的稳定，也为了降低实际运行成本，导热油系统应该选用波纹管截止阀，不能选用填料密封的截止阀或闸阀。
