用法例句

Ethylene glycol monoethyl ether acetate(EGEEA) was synthesized by the esterification reaction of acetic acid with ethylene glycol monoethyl ether in the novel catalyst of polymer compouned which is FeCl_3-AlCl_3-UR.

　以乙二醇单乙醚和冰乙酸为原料,在新型高分子复合催化剂FeCl3-AlCl3-UR的催化下,合成了乙二醇单乙醚醋酸酯。

We prove that,under UR condition of polynomial map in Q-jet J~Q(F),DF(O)x is the smooth normal form of F (x) near its hyperbolic fixed point.

通过使用正规形方法证明了若局部微分同胚F(x)的Q射式中的p次多项式映射代表满足UR条件,则在双曲不动点O附近光滑共轭等价于映射DF(O)x,也就是说,DF(O)x是在双曲不动点处的光滑正规形。
