嵌段共聚物

Size of the vesicles can be controlled by the components of the blocks and their ratio in the copolymers.

不同嵌段组成和它们在共聚物中的比例可以控制囊泡的大小。

The plastic alloy is refers to two kinds of or two kind of above polymers becomes the microscopic phase splitting macroscopic even multi-components system through some way blending, the plastic alloy both includes the product of the pure physics blending, and includes block, the graft copolymer as well as the polymer compound material which the chemical change becomes during the course of milling.

塑料合金是指两种或两种以上聚合物通过某种方式混合而形成微观分相宏观均匀的多组分体系，塑料合金既包括单纯的物理混炼产物，又包括嵌段、接枝共聚物以及混炼时发生化学变化而成的聚合物复合材料。

Two types of three-arm or four-arm star-shapedPCL-b-D,L-PLGA50 copolymer with high molecular weight and narrow molecularweight distribution were synthesized via the block copolymerization of MG monomerwith star-shaped hydroxy-terminated PCL as macroinitiator and 〓 as catalyst.

以端羟基化的三臂或四臂星型PCL聚合物为大分子引发剂、〓为催化剂，引发MG单体的嵌段共聚合，合成了高分子量和窄分子量分布的三臂或四臂星型PCL-b-D，L-PLGA50共聚物。

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。
