沉淀法从卤水中提取硼对于硼资源的开发利用具有重要意义。

Results show that when the boron content is 8.3%, the B/CuO delay compositions are misfired, and the burning rates increase with increasing of boron contents from 11 % to 20%.

结果表明：当硼含量为8.3%时，硼／氧化铜延期药不能完全燃烧，出现瞎火；在硼含量为11%~20%范围内，随着硼含量的增加，随硼含量增加，硼／氧化铜延期药的燃速增加。

The experiment results show that the lowest synthesis pressure changed with the different proportion of added boron. At the same time, from the color change of synthesized diamond, we can see that it is an effective method to improve the content of boron in diamond crystal.

实验结果表明，随硼添加比例的不同，合成金刚石的最低压力点也不同；同时，通过不同添加比例的硼合成出金刚石的颜色，可得知该方法对提高金刚石内硼含量的有效性。

It is also found that the distribution of boron in diamond is asymmetric, and poor shape crystals and polycrystalls tend to form with the increase of the content of boron in diamond.

同时，实验还发现，硼在晶体中的分布情况存在着区域性，以及随着晶体内硼含量的增加，晶体晶形变差，而且容易生长聚晶。
