共轭轴

The chiralMn complexes, especially Jacobsen\'scatalyst, display high enantioselectivity for asymmetric epoxidation of conjugated cis-di-, tri-and some tetrasubstituted prochiral alkenes in the NaClO biphasic system, but the epoxidationreaction generally requires a long reaction time even in the presence of an axial ligand.

在NaClO两相体系中，手性Mn配合物，尤其是Jacobsen催化剂，对共轭顺式二取代、三取代和部分四取代烯烃的不对称环氧化具有高的对映选择性，然而即使存在轴向配体，环氧化反应也通常需要长的反应时间。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
