Soil Ca2+ content increased by 0.749mmol/kg, Mg2+ content increased by 0.169mmol/kg, the Na++ K+ content dropped by 9.52mmol?kg, SO42- increased by 0.091mmol?kg, Cl- reduced by 1.727mmol?kg, the HCO3- content in the soil assumed the obvious dropping tendency, it might be explained that the advancement of HCO3- has transformed into CO32- in the oasis, and has formed precipitation with two price calcium magnesium heteropolar ,then fix in the soil layer.

4土壤Ca2+含量增加了0.749mmol/kg，Mg2+含量增加了0.169mmol/kg ，Na++K+含量下降了9.52 mmol∕kg，SO42-增加了0.091 mmol∕kg， Cl-降低了1.727 mmol∕kg，土壤中HCO3-的含量呈明显下降趋势，可解释为在绿洲化进程中HCO3-转化为CO32-，并与二价钙镁离子结合形成沉淀固定于土层中。

Resolution of benzoin,hydrobenzoin and α- phenethyl alcohol with-phenylglycine based chiral stationary phase(Chirex 3001)in the normal-phase conditions were studied.

正相模式下研究了安息香、氢化安息香及α-苯乙醇在苯基甘氨酸型手性固定相Ch irex 3001上的拆分，探讨了流动相组成及柱温对手性拆分效果的影响。

American Dupont NOMEX fragrant gathers the amide paper, it is (chromatographic analysis textile fiber and short fiber) is composed of two kind of shape aromatic polyamide polymer, uses the special papermaking or the system board method, agglutinates Cheng Jibo the fibrous reticulum, undergoes high temperature high pressure processing, carries on the densification and the calendering causes them reliable to fix lowly in the same place, becomes not penetrable, electrical and mechanicalness energy level high whole.

美国杜邦NOMEX芳香聚酰胺纸，它是是由两种形态的芳香族聚酰胺的聚合物组成，使用特殊的造纸或制板方法，粘合成极薄的纤维网，经过高温高压处理，进行密化和轧光使它们牢固低固定在一起，成为不可渗透的，电气和机械性能极高的整体。

Prophenoloxidase is a key enzyme for mediating melanotic encapsulation of oocysts,which may be transformed into active phenoloxidase by limiting proteolysis.

而前酚氧化酶(Prophenoloxidase，PPO)是介导卵囊黑化包被反应的一种关键酶，活化后可催化酪氨酸羟基化为二羟基苯基丙氨酸，二羟基苯基丙氨酸和多巴胺可进一步氧化为具有活性的苯醌活性，苯醌即可介导蛋白交联并聚合成黑色素层固定、隔离或杀死入侵的病原体。

Methods: With enzyme linked immunosorbent assay and micronize strengthening immunofixation, The serum OX-LDL and HS-CRP level of 215 patients with ACI was measured on the second day after hospitalization. In addition, 30 healthy volunteers were taken as the control group.
