2. After processing, the purities of nobiletin and tangeretin were improved 3.7 times and 3.2 times, respectively. 经过处理后川陈皮素和橘皮素的纯度分别提高了3.7倍和3.2倍。
3. From these data of resistivity, the prower consumption and the purities of liquid crystal material can be eveluated. 用该方法测得的电阻率数据比较稳定,基本上能够准确反映液晶材料的纯度及功耗。
4. The recovered sulfur generally had purities higher than 96.5%, and the sulfur recovery efficiency were higher than 90%. 试验结果表明,回收的硫磺纯度在96.5%以上.硫的回收率在90%以上。
5. Synthesizing very long alkanes is not trivial, especially in the quantities and purities required to put these simulations to the test. 合成很长的烷烃并不轻松,尤其是达到实验所需要的数量和纯度。
