同系化反应

All these lead to a suggestion of a two step method technical route in which CH 4 and CO 2 can be converted into high value products at low temperature directly.

对近年来 CH4 的低温活化的研究结果进行了评述，结合对 CH4 的两步反应同系化及CO2 加氢研究成果，提出了由 CH4 - CO2 低温转化直接合成 C2 +含氧化合物的两步法技术路线及催化剂体系，论证了其可能性

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。
