Lens checks fiber bronchus bronchus of fiber of all patient classics all is checked before lens examination phlegmy look for 1~3 of the bacili that fight acid second, outside dividing positive of 2 phlegmy bacterium, electronegative; is in Yu Wei fiber bronchus lens is orthoptic next observation tracheal, bronchus reach each lung paragraph, bronchus mucous membrane, live via taking check, brush check to do pathology cytology examination and bacteriological examination; with the film inside bronchus unusual organize via pathology change for tuberculosis or n/med tuberculosis of the film inside diagnostic bronchus of positive of smear of n/med tuberculosis bacterium.

三、纤维支气管镜检查所有患者经纤维支气管镜检查前均查痰找抗酸杆菌1~3次，除2例痰菌阳性外，余为阴性；在纤维支气管镜直视下观察气管、支气管及各肺段、支气管黏膜，经取活检、刷检做病理细胞学检查及细菌学检查；以支气管内膜异常并经病理组织为结核病变或结核菌涂片阳性诊断支气管内膜结核。

From the results of IR and XPS spectrocopy. The cationic sol components H〓SiO〓 and 〓 of the solution trend to adsorp on the surface of electronegative aegirine because of electrostatic acctraction each other, and interrupted the collector's reaction with Fe〓 on the surface. Hence the flotation of aegirine was decreased, on the other hand, there is electrostatic repulsion between the surface of hematite and the cationic sol H〓SiO〓.〓, Which has advantage to dispersion of hematite particles, therefore, the hematite flotation is achieved sucessfully with anionic collector.

根据红外光谱和XPS测试结果可知，在弱酸性介质中，活性硅酸胶体抑制剂中荷正电的胶团H〓SiO〓及〓由于电性吸引而选择性地覆盖在荷负电的钠辉石表面，从而阻碍了阴离子捕收剂与表面Fe〓的配位作用，导致钠辉石的浮游被抑制；而赤铁矿表面由于荷正电，与矿浆中的H〓SiO〓、〓等硅酸胶团存在着电性排斥作用，有利于赤铁矿颗粒的稳定分散，所以赤铁矿能够被脂肪酸捕收剂吸附而选择性上浮。

But afore-mentioned case of illness are the fastest the 6 H after art is the slowest 20 H appears cannot sit quietly, companion breaks up to have quiver on eyeball, brothers Xu is moved, slant first, neck rigidity, flesh is clonic, present opisthotonos individually, but nonexistent pathology is reflexed (Ba Bin this base electronegative).

但上述病例最快术后6 h最慢20 h出现不能静坐，眼球上翻伴有震颤，手足徐动，偏头，颈强直，肌阵挛，个别呈现角弓反张，但不存在病理反射。

These include physical characteristics, such as repulsive forces resulting from the electronegative charge of both platelet and endothelial cell membranes, and biochemical attributes, such as the synthesis and release of inhibitors of platelet activation. Platelets respond rapidly to alterations of endothelial cells and to exposure of subendothelial structures by attaching firmly to the site of the lesion.

正常情况下，循环中的血小板与血管壁内皮细胞层紧密接触但不发生黏附，是因为血管内皮细胞具有一定的活性功能，包括一些物理特性如血小板和内皮细胞膜均带有负电荷产生相互排斥作用以及生化作用如合成和释放血小板活化抑制剂。

The electron location function shows the electronic density changes at both the atomic vacancies and antisites. There is an obvious absence of electronic areas where the vacancy of Ga has the dangling bonds of N, which are favourable for the sdsorption of metal atoms. In contrast, at the vacancy of N, there is more electron distribution(ELF:0.16-0.45), forming lone electron pairs which are profitably available to combine electronegative atoms.

电子局域函数显示了表面空位和替位处的电子密度变化，表面Ga原子空缺处有非常明显的缺电子区域，悬挂键临近N的电子密度增大，有利于对金属原子的吸附；N原子空位处的ELF值为0.16-0.45，有利于同电负性较大的原子结合。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
