Since polar organic crystals have noncentric structures, the existence of polar axis in the crystals has a significant effect on the molecular arrangement and on the crystal growth.

極性有機晶體在不同的溶劑中具有明顯不同的生長習(xí)性，主要有兩個方面的原因：一是極性有機晶體屬非中心對稱性晶類影音先锋欧美性爱色资源，晶體具有極軸2018亚洲精彩偷拍视频，極軸的存在對分子堆積和晶體生長具有重要影響；另一是極性有機晶體的界面結(jié)構(gòu)不同www.黄色av.com，溶劑與晶體界面的相互作用不同免费在线不卡av，使得晶體同一面族的生長速率不同，從而導(dǎo)致了晶體習(xí)性的改變一边摸一边捅。

It was determined that it would cause massive earthquakes, volcanoes, tidal waves, the melting or shifting of the polar ice caps, sudden fluctuations in temperature and climatic conditions, and probably a shift in the polar axis of Earth.
