Recent advances in preparation of barium carbonate particles were reviewed.

综述了碳酸钡粒子制备方面的进展。

Barium strontium titanate nanoparticles were successfully prepared by the low temperature (300-500℃) calcination method, using barium hydroxide, strontium hydroxide, and tetrabutyl titanate as starting materials.

以氢氧化钡、氢氧化锶和钛酸丁酯为原料，采用低温煅烧(300~500℃)法合成了钛酸锶钡纳米粒子。

New findings suggest that Chinese villagers were brewing alcoholic beverages as long ago as 7,000 years B.C., just before barley beer and grape wine were starting to appear in the Middle East.

他们分析中国专家提供的陶器碎片时发现，其中吸附并保存下来的粒子来自某种发酵饮料。而有3000多年历史的鹿邑青铜壶内现在仍为流体的内盛物，更显然是古酒实物。

For example, if you set the angle values here to Start Angle=0 and End Angle=45, the particles are emitted within a total of a 90-degree cone, with 45 degrees on either side of the base vector.

例如，如果用户设置起始角度值为0，结束角度值为45。那么粒子将在总共为90度的锥角内发射。也就是在基本向量两边都为45度角的椎体体积内。

As you may already know, particles can be used to do just about anything you could possibly imagine.

简介 正如您可能已经知道，粒子可以用来做几乎任何你可以想像。
