青霉素之所以能既杀死病菌，又不损害人体细胞，原因在于青霉素所含的青霉烷能使病菌细胞壁的合成发生障碍，导致病菌溶解死亡，而人和动物的细胞则没有细胞壁。

Phenylmethylsulfonyl fluoride (174.2 mg/mL), chicken ovomucoid (1000 mg/mL) and soy-bean trypsin inhibitor (1000 mg/mL) could inhibit enzyme activity, which indicated that the enzyme belonged to serine protease group. On plasminogen-free fibrin plates and plasminogen fibrin plates, the fibrinolytic activity had no obvious difference, indicating that the enzyme was a fibrinolytic enzyme which degraded fibrin directly, but not a plasminogen activator which degraded fibrin by activating plasminogen.

此菌株产生的纤溶酶在50℃以下和pH5.0~11.0范围内具有较好的稳定性，最适作用温度为42℃；最适pH值为9.0；Mg2+、Ca2+对此酶有明显的激活作用，而Cu2+能完全抑制酶的活性；174.2 mg/mL的苯甲基磺酰氟、1000 mg/mL的鸡卵类粘蛋白和1000 mg/mL大豆胰蛋白酶抑制剂能完全抑制酶活性，初步说明此酶属于丝氨酸蛋白酶类；体外溶纤作用表明，该酶溶解纤维蛋白的方式是直接溶解，而不是通过激活纤溶酶原。

The results show that Sb addition can diminish the crystal grain, but the content of segregative phase at crystal boundary increases, and the current efficiency of material is low. Compared with Sb addition, Sn addition can also diminish the crystal grain, the current efficiency increases, the content of segregative phase at crystal boundary reduces, but diffusional corrosion of the anode surface is not uniform. The cooperation of Sb and Sn can prevent Si from segregating effectively and enhance the current efficiency obviously. At the same time, anode materials have preferable surface dissolution characteristics.

结果表明： Sb具有细化晶粒的作用，但晶界存在较多偏析相，电流效率偏低；与Sb相比较， Sn也具有细化晶粒的作用，电流效率有所提高，晶界偏析相较少，但阳极的表面腐蚀溶解不均匀； Sn和Sb的协同作用在于能有效地抑制Si的偏析，显著提高阳极的电流效率，使得阳极表面具有良好的腐蚀溶解性。

At the same time, the fouling mechanism of membranes given in this thesis can give a reasonable explanation on the change of membrane performance. Our results show that the magnetization of membranes can effectively improve the anti-fouling ability of the PAN- Fe_3O_4 membrane. The obtained result may give insight to the development of new membranes with a good anti-fouling performance in the filtration of blood solution. No chemical bond was found between PAN and Fe_3O_4 in the membrane at room temperature. The addition of Fe_3O_4 can improve the temperatures of dehydrogenated reaction and decomposition of PAN but dot change the glassy transition temperature. The resistance against acid is stronger than the resistance to base for a PAN- Fe_3O_4 membrane.

结果表明在PAN- Fe_3O_4超滤膜制备过程中使用外加磁场作用能有效提高膜的耐污染能力，这一结果为开发适用于血液处理的耐污染超滤膜提供了一种新途径；在PAN- Fe_3O_4超滤膜中，四氧化三铁与PAN在室温下没有形成化学键，也不存在官能团之间的相互作用；添加Fe_3O_4对膜的玻璃化温度没有影响，但能提高PAN环化脱氢反应的温度和分解温度；PAN- Fe_3O_4超滤膜的耐酸性强于耐碱性，在pH值为10以上的溶液中由于水解作用而溶解，使得膜失去使用价值，膜的耐酸性与酸的种类、浓度和氧化性有关。

The results suggested that chitinhad a good solubility in the new solvent when its at -30℃and below, but the solubilityof chitin no longer increasesd notable as the temperature reduced; The joined of urea, incertain degree, strengthened the solvency of alkali solvent to chitin. When theconcentration of sodium hydroxide is 8%～12%, Chitin had a good solubility, and theapparent viscosity of chitin solution could up to 4000 mpa·s～5000mpa·s at roomtemperature; In addition,the solubility of chitin in new solvent was high when therefrigerated time was three days and above, but the refrigerated time could not too long,otherwise, the deacetylize degree of chitin got more bigger. The properties of chitin solution were tested by revolving viscosimeter, FT-IR,X-RD and so on.

结果表明，在-30℃及以下甲壳素能很好的溶解于新溶剂中，但甲壳素的溶解度不再随温度的下降而有所增大，而是基本保持不变；尿素的加入，在一定程度上强化了强碱溶剂对甲壳素的溶解，当新溶剂中NaOH浓度为8％～12％时，甲壳素在试验温度下可以获得较好的溶解度，所得溶液在室温下的表观黏度达4000 mpa·s～5000mp·s；冷冻时间为3 d及以上时，有利于甲壳素的溶解，超过3 d，甲壳素的溶解度变化不大，另外，冷冻条件下，甲壳素在强碱溶剂中仍会发生脱乙酰化反应，冷冻时间不宜太长。

As one of the most important osmoregulation actor, firstly,Proline plays a keyrole in the osmotic potential adjustment in plant cells. Secondly, Proline can preventNaCl from damaging the structure of biomacromolecule in cells. Thirdly, the highdissolubility and non-rejection capability of Proline can enlarge the solution volumnof the cell, so the concentration of salt will be diminished in cytoplasm and the saltstress will be relieved. Forthly, the accumulation of Proline could prevent thedehydrolysis from sap cavity in cytoplasm. Fifthly, the synthesis of plant chlorophyllwill be diminished under the salt stress, but the Proline can provide request ofchlorophyll synthesis.

脯氨酸作为渗透调节剂对植物体细胞渗透势的变化起重要作用：一，在盐胁迫下，脯氨酸在植物体内是一种重要的渗透调节剂，它是一些高等植物和绿藻抗盐和抗旱的主要渗透剂之一；二，脯氨酸可以保护细胞中的生物大分子的结构，使之不被NaCl破坏，并能维持其完整的水合范围；三，脯氨酸的高度溶解性以及其对植物各种酶活性不抑制性，可以扩大细胞的溶解容积，从而降低细胞质液中盐的浓度，减轻盐的胁迫作用；四，细胞质中积累的大量脯氨酸可以防止液泡对细胞质的脱水作用；五，在盐胁迫下，植物叶绿素的合成受到抑制，叶绿素的合成需要脯氨酸。
