The linear regression analysis shows that the distribution of average annual precipitation in the front mountainous area is mainly affected by height abore the sea level and that the distribution of average annual preci- pitation in the back mountainous area is mainly affected by geographical position in Beijing area.

根据线性回归分析表明，北京地区年平均降水量的分布前山区主要受海拔高度的影响，后山区主要受地理位置的影响。

Esterification with some inorganic acid chlorides and anhydrides has been studied too, but with limited success only due to rather violent side reactions and an early precipitation of the reaction products.

同时也做过用无机盐酸及酸酐酯化的研究，但是只取得了有限的成功，只是因为相对剧烈的副反应及反应产物过早的沉淀。toommy：感谢参与，继续努力！亚太币+ 30 贡献+ 2
