The wall of the burning chamber was pitted at the beginning then gradually burnt through.By means of the Bunsen burner,tubular furnace and XRD,SEM,EDS,this special type of high-temperabure destruction was studied.It was found that the phenomenon is resulted from the combined action of CO and lower hydrocarbon on Ni-Cr alloy.Firstly,Ni-Cr alloy is carbonized and selectively oxidized by CO to produce Cr2C,Cr3C2 and Ni-Cr2O3,while the capillary cracks in the surface layer are formed simultaneously.

作者利用几种现代手段和试验方法，对这一燃烧破坏现象进行了系统地模拟研究，发现这是CO和低分子烃在高温下对合金共同作用的结果：第一步CO作用使合金表层发生氧化和碳化，造成裂隙；第二步低分子烃扩散进裂隙并在Ni-Cr2O3微粒的催化下，裂解生在石墨炭并包复在Ni-Cr2O3微粒周围，体积增大。

The results indicated that immobilized E2 protein remarkably raises the level of phosphorate-tyrosine in Raji cells , but the soluble E2 protein hasn't obvious impact to phosphorylation of tyrosine of Raji cell. It was presumed that immobilized E2 protein was resembled to natural viron enveloped E2 protein and may more efficiently interact with CD81 molecule.

这可能是因为固相化的E2蛋白类似天然的病毒颗粒，在构象上要更接近于天然的病毒颗粒表面E2蛋白，而且固相化后的E2蛋白在单位体积的密度要高于可溶性的E2蛋白单位体积的密度，使其能够更充分的与细胞表面的CD81分子相互接触作用。

So it can keep invariable bulk phase transition within a wild neutralization range;AB-I and AB-II show the similar phenomenon in bulk phase transition,but not very similar in methanol and ethanol.Perhaps this is because of competition between hydrophile and lyophobic.

AB-I样品分子链上的磺酸基团(-SO3-)完全电离，与树脂网络外部溶液浓度差始终较为恒定，所以能在较宽的中和度范围内(40%～80%)保持较为恒定的相变体积；AB-I和AB-II在电解质溶液中表现出类似的体积相变规律，而在甲醇、乙醇中表现出不尽相同的相变规律，这可能是由于AB-II中存在亲水力和疏水力相互竞争作用的结果。

The relative small o-Ps lifetime (1.48—1.63ns) can beexplained by the rigidity and high packing density of molecule chain, due to theintrachain and interchain hydrogen bond interaction respectively, whereas in 〓-containing chitosan, the grafted 〓 that play a significant chemical inhibition andquenching role on positronium formation and annihilation is first observed.

CS的相对小的尺寸和较低的自由体积浓度归因于氢键作用而致分子链较为致密的堆砌，在〓-CS中首次发现了〓基团对正电子素湮没的抑制和猝灭作用，此时〓和〓不再直接对应于自由体积尺寸和浓度。

Selective external biliary drainage could improve liver function. It may result from an increase of the future remant volume and the molecular mechanism might be associated with elevation of per volume expression hepatobiliary membrane transporters.
