covalent compound

This indicates that PLZT belongs to a mixed ionic covalent compound.

这说明在PLZT中，电荷的转移是不完全的，它属于离子共价混合的化合物。

The experimental results show that the molecules ( methylene blue and thionine) can bind to outside surface of PSAF shell directly. Opposite, PSAF can entrap and store these molecules as a covalent compound into its protein shell.

实验结果表明，有机小分子（亚甲蓝及劳氏紫）络合于PSAF蛋白壳外表层的同时，又被PSAF捕获，并以共价化合物方式储存于蛋白壳内。

However, as a covalent chemical compound with the wurtzite crystal structure, A1N is not easy to sinter.

然而，A1N是强共价键化合物，烧结活性低，而且A1N很容易水解引入氧杂质。

But aluminum nitride is covalent bond compound with high melting point and low self-diffusion coefficient, and usually it can be used to prepare high dense aluminum nitride ceramic by hot pressing sintering.

但氮化铝为强共价键结合物，熔点高，自扩散系数小，通常需要热压烧结才能制备出高致密的氮化铝陶瓷。

Silicon carbide was a strong covalent bond compound, which had favorable high temperature, electricity, mechanism and chemistry capability.

碳化硅材料是共价键极强的化合物，具有良好的高温性能、电性能、机械性能和化学性能。
