After two decades, 95 percent of the elemental mercury on the surface of a filling had gone through a chemical reaction. It became beta-mercury sulfide, a black-colored solid.

经过了20年的光阴，旧填充物表面有95%的汞元素已经发生了化学反应，它变成了黑辰砂(beta - mercury sulfide)，一种黑色的固体。

The height computation model of fluidize-bed showed that the bed height is mainly influenced by catalyst filling amount, linear speed of reaction gas and particle size of catalyst.

流化床高度计算模型表明，床层高度主要受催化剂装填量、反应气体线速和催化剂粒度的影响。

At present, the main ways of the improvement and modification of this technology put in a nutshell in the catalyst filling in the reaction district of the non-thermal plasma.

目前，该技术的完善和改进的主要途径归结于在等离子体反应区填充催化材料上。
