This paper deals with making stop bleeding sponge with dried small shrimps. Firstly breaking away with inorganic salt and proteir in the dried small shrimps with acid and NaOH, secondly, taking off vinyl-in the chitin with 50% NaOH, temperature is 110 ℃. the last, reacting with chitosamine and PVA-124 make stop bleeding sponge were produced, catalyst is PdCl 2. The sponge film and sparkce is setatisfaction.

用虾壳经除盐，去蛋白处理后，用50％的NaOH溶液在110℃的温度下脱乙酰基制备壳聚糖；以1∶9的稀醋酸溶作溶剂，氯化钯作催化剂，甲苯二异氰酸酯作发泡剂、交联剂，使壳聚糖与PVA－124进行交联成膜，发泡用氨水洗成中性后在80℃的红外灯烘箱下烘干，制得止血海棉

Dispersant, comburent, frother and mineralizer were added in the system successively, then it needed several minutes to combust at 600℃ directly, the non-grinding long afterglow powdery material SrAl_2O_4∶Eu~(2+),Dy~(3+) was obtained.

向体系内添加分散剂、燃烧剂、发泡剂和矿化剂，于低温下进行燃烧-发泡反应，一步制备了不球磨的SrAl2O4∶Eu2+，Dy3+长余辉粉体材料。

Based on a lot of experiments, it shows the distinct error between classical theory curve which express the relation of cell diameter, cell density and foam tensile strength , tensibility tensile product and re-spring degree and experiment curve. It also can＇t explain the relation of hole degree , area of cell wall with above four mechanics parameter. But the sub-cluster scale theory was demonstrated successfully to explain the relation of cell structure and foam mechanics property on different mold temperature, mold pressure, mold period and different chemical blowing agent, blowing activator content.

通过大量的实验结果理论分析表明：以往的经典理论存在着很多不足之处，它不能有效地解释孔径、泡孔密度与抗拉强度、断裂伸长率、断裂功、及回弹率之间的理论曲线与实验曲线之间的偏差，也不能解释空隙度、泡孔壁厚与上面四者之间的关系，而群子标度理论则成功地论证了在不同模压温度、模压压力、模压时间及不同用量发泡剂、发泡促进剂条件下泡体力学性能与结构之间的相关性。

The apparent density of the porous PLA decreased with increasing content of nucleating and foaming agent.

结果表明，发泡剂与成核剂的增加能降低发泡PLA的表观密度，增加其泡孔密度。

In the PE blowing procedure, mold temperature, mold pressure mold duration are the essential conditions and the mold temperature determine the decompose speed of blowing agent AC and cross link agent DCP.

在PE发泡工艺中，温度、时间、压力是不可缺少的工艺条件，其中温度决定了发泡剂、交联剂的分解速度。

At the rear was an innovative combination transaxle with the gearbox, clutch, differential, and inboard-mounted drum brakes.
