Methods The experimental TBI model was established by bumpiness of free falling body according to Feeney′s.The rats′cerebral edema were imaged with magnetic resonance image,The changes of brain water content and permeability of blood-brain barrier were measured by the methods of wet and dry weight and Evans blue fluorometry.The expression of AQP-4 mRNA was examined by reverse transcriptase polymerase chain reaction.

The results showed that heat treatment had no obvious effect on main linkage way of the system. Between 500℃and 900℃, the crystal phase CaF_2 was precipitated firstly, with the rising of temperature and the prolonging of time, crystal phases such as Al_2SiO_5、Ca_2SiO_4 and Ca_3(PO_4)_2 were precipitated sequentially and the powder was changed from dispersive spheroidic to irregular strip that linked each other, and congregated to irregular mass, gradually.

热处理对体系的主体键连方式无明显影响；在500-900℃温度范围内，粉体优先析出CaF_2晶相，随着加热温度的升高及保温时间的延长，依次析出Al_2SiO_5、Ca_2SiO_4、Ca_3(PO_4)_2等晶相，粉体由分散的近球形颗粒转变成相互粘连的不规则带状，并逐渐聚合成不规则块状；固结体抗压强度逐渐增加后趋于平缓。

The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas. Using above measurements, we can concluded that PS-b-PNIPAM-b-PDMA triblock copolymer micelles have the double phase transition behavior, while PS-b-PDMA-b-PNIPAM have only one phase transition behavior.2. We synthesized poly(ethylene glycol-b-methacrylic acid)diblock copolymers with three different polymerization degree of PMAA blocks.

但是对于PS-b-PDMA-b-PNIPAM胶束，由于中间亲水嵌段的作用，使PNIPAM的相转变温度提高，且PDMA由于靠近PS内核以及随着外壳PNIPAM的水溶性变差其相转变点降低，因此我们只能看到一个转变过程。2、通过原子转移自由基聚合，我们合成了三种不同PtBMA长度的PEG-b-PtBMA二嵌段聚合物，将叔丁基水解后得到了三种PEG-b-PMAA二嵌段聚合物。

It is reason that more Ca~(2+) can destroy the balance of electrostatic and hydration shell in the milk system hardly.Homogenization is key to the pinenut milk process attributed to emulsifies enhanced the particles interaction and stability.

它使稳定剂和松仁乳的分散相充分混合，相互作用，降低了颗拉的直径，稳定剂在颗粒表面形成稳定的保护膜和水化层阻止了分散相的聚合。

The featuresof this method are obtained, i.e. the degradation of PP is not avoided, MAHcan be reacted inside the PP particles by diffusion, grafted polymer has higherpyrolytic degradation temperature than pure PP, the sizes of crystallite ingrafted polymer are smaller than those of pure PP.
