The results indicate that in the same reaction conditions the powders prepared by ammoniated silicon sol had smaller pellet diameter and bulk density than the direct sol-gel handling metho...

结果表明：采用氨解硅溶胶方法制得的原料粉末比直接溶胶-凝胶方法制得的粉末颗粒直径细小，团聚松散，堆积密度小。在同样合成条件下前者反应获得的碳化硅的转化率高，晶须含量高，质量好。

The working process of set is as follows; the liquid of raw material is pumped in through diaphragm pump. The liquid of raw material atomizes into tiny droplets. Then it gathers with hot air and fall off. Most parts of powder material will be collected through the outlet of discharge at the bottom. The wasted air and fine power will be separated through cyclone.

本机组工作过程为料液通过隔膜高压输入，喷出雾状液滴，然后同热空气并流下降，大部分粉粒由塔底排料口收集，废气及其微小粉末经旋风分离器分离，废气由抽风机排出，粉末由设在旋风分离器下端的收粉筒收集，风机出口处还可以装备二级除尘装置，回收率在96-98%以上。

Changing temperature and humidity during transport and storage may lead to caking of these products, which makes it more difficult for the final user to process them.

这是由于这一事实，即硅胶信封粉末，从而作为空间持有人之间的个别领导粉末粒子的水到空格。

In order to acquire the heating-cooling process of laser molten pool and the mutual effect of sintering layers in multi-layer powder sintering, factors such as heat conduction, heat radiation, heat convecting and changeable thermophysical property parameters were taken into account comprehensively, the 3D transient state FEM of the temperature field of multi-layer thin-wall metal parts formed by DMLS was established based on ANSYS. The APDL (ANSYS Parametric Design Language) was used to carry out thermal resource moving and the technique of birth/death for element was used to simulate the process of material addition.

为掌握多层粉末烧结过程中激光熔池的加热冷却规律以及各烧结层之间的相互影响，综合考虑热传导、热辐射和热对流以及材料的高度非线性，基于ANSYS平台建立了多层金属薄壁件的三维温度场有限元模型，利用APDIJ语言编程实现模拟中激光热源的移动，采用&单元生死&技术描述粉末材料动态增长过程。

It is shown that uniform powder cloth with proper thickness can be produced by using appropriate rolling parameters. Thermogravimetic and pyrolysis residuum analysis indicate that the burnout process of fugitive binder used to produce the cloth is found to take place in two stages, no residuum is left when degassed properly.

结果表明，采用合适的轧制参数即可容易地获得厚度合适、均匀的粉末布；热失重分析和热解残余物分析指出用来制备粉末布的有机粘结剂的去除过程分成两个阶段，合理除气后，基本没有残余物。

The results show that the coating surface of electrodeposited pretreatment powder is uniform, and the wear resistance is improved.

结果表明，电镀Cu预处理粉末的喷涂层表面较为均匀，耐磨性约为粘结破碎法预处理粉末喷涂层的2倍。

When plastic powder gets in these seats, the powder extrudes.

当塑料粉末进入这些阀门的阀座时，塑料粉末就会被挤压。

The oxygen content of the product can be controlled below 500PPM. Our Alloy Powder "Tianta" is the earliest fluxed alloy powder registered in China.

也是国内生产自熔性合金粉末唯一最早的进行商标登记注册的———&天塔&牌合金粉末。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
