查询词典 crystals

The transmission magic-mirror method was applied to visualize and record the whole process of growth and melting of transparent crystals taking place in high temperature up to 1000℃ For matching to three-dimensional observation, a set of special furnace and crucible was designed and the growing process can be observed in two perpendicular directions and recorded in situ by CCD camera simultaneously.

最近开发了三维光学实时观察法，应用透视魔镜法实时观察并记录透明晶体的生长和溶解过程，最高使用温度为1000℃配合三维观察，设计并制造了一套独特的生长炉和坩埚，有二组互相垂直的光路可同时实时观察晶体生长过程，并通过CCD摄像头进行同步记录。

The calcium sulfate was dissolved and led to the rapid increase of calcium ion concentration in the solution. So the calcium sulfate is not suitable for being seed crystal of low-salt concentration. The quartz sand and calcium carbonate both can be used as seed crystals, but it is much faster and more complete to use calcium carbonate as seed crystal compared with using quartz sand.

当硫酸钙加入处理液中发生了硫酸钙溶解现象，导致溶液钙离子浓度迅速增加，故硫酸钙不适合做低浓度盐水的晶种，而石英砂和碳酸钙均能对钙离子的结晶起到效果，但碳酸钙做晶种对钙离子的结晶更快捷、更彻底，在条件允许的情况下，采用碳酸钙做晶种为宜。
