枝链淀粉

The effects of concentrations of monomer and initiator and temperature on copolymerization were investigated.

接枝共聚物在1650、1616和1416 cm-1（聚丙烯酰胺PAM的特征吸收）处的红外光谱表明，在淀粉链上引入了酰胺基。

The atomic net charge, population of frontier molecular orbital, stability and reactive properties of free radicals were analyzed, the mechanism of graft polymerization was discussed.

同时采用量子化学abinitio UHF方法在6-31G基组水平上对两类淀粉链段自由基模型进行几何优化，分析体系的净电荷、前线分子轨道分布规律，以及自由基的稳定性和反应活性特征，揭示接枝共聚反应机理。

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。
