For a long time, one-sided benthamism is the major reason which leads to this situation. It brings on knowledge structure of students single and weak, what's more, students have fed up with studying because teaching process is formulistic. Poetry is one important part of Chinese education.

长期以来，片面的教育&工具—功利意识&是形成这种现状的主要原因，给受教育者带来文化结构单一、薄弱的危害；而教学流程模式化、公式化，又使学生形成普遍的厌学心理。

The results showed that at the anaerobic phase, the PHB concentration in the cell and orthophosphate concentration of the anaerobic effluent obviously increased, the poly-P concentration in the cell decreased, and the cucci and bacilli with a size of 1.0~1.5 μm were dominant and formed grapy cellular cluster. At the anoxic phase, the PHB concentration and orthophosphate concentration decreased significantly, the amount of poly-P increased, and the elliptical cucci of 0.5~1 μm and spheral bacilli of 1.0~1.5 μm were dominant. At the aerobic phase, the PHB and orthophosphate concentration almost reduced to zero, the poly-P increased significantly, cucci appeared single or in pair, and the contour of sphere was blur and almost disappeared.

试验结果表明，在厌氧阶段，微生物细胞内PHB的量大幅提高，上清液中磷酸盐的含量上升，聚磷酸盐含量明显下降，粒径为1～1.5 μm、呈球状和棒状的菌群构成的葡萄状细胞簇占居优势；在缺氧阶段，微生物细胞内PHB的量下降，上清液中磷酸盐含量下降，聚磷酸盐含量上升，粒径为0.5～1 μm的椭球菌与1.0～1.5 μm的球杆菌占优势；在好氧阶段，微生物细胞内PHB的量较低或接近零，上清液中磷酸盐的含量接近零，聚磷酸盐含量明显上升，此时粒径1.0～1.5 μm的球菌以单个或成对出现，球菌不再饱满，呈现接近消失的状态。

The most common isolates were α-hemolytic streptococcus, Hemophilus influenzae, Streptococcus pneumonia, coagulase-negative Staphylococcus, and Staphylococcus aureus. Anaerobes were recovered from 7.9% of all isolates.

最常见的菌种依序是α-hemolytic streptococcus，Hemophilus influenzae，Streptococcus pneumonia，coagulase-negative Staphylococcus以及Staphylococcus aureus，厌氧菌则占所有菌株的7.9%。

The recent advancement of the relevant study on hexavalent chromium pollution in electroplating waste water is reviewed.

Cr主要被吸附在固体物质上面而存在于沉积物中；Cr多溶于水中，而且是稳定的，只有在厌氧的情况下，才还原为Cr。

Meanwhile it was pointed out that with homofermentative LAB, recirculation of cells and in situ production removal technology under anaerobic condition, LA yield could be increased and co-inoculation of various LAB with the optimizing LA separation technique could help to the industrialization of LA production with organic wastes.

指出在厌氧条件下应用同型发酵乳酸细菌，采用原位产物分离技术和细胞再循环发酵通常会提高乳酸的产量；采取多菌种的联合发酵并优化提取工艺，将有助于实现有机废物工业化生产乳酸。

In addition, the hydrolytic acidification benefit to the anaerobic treatment.

另外，水解酸化反应器出水为厌氧反应器提供了很好的生态条件。

Zeta potential was -44.23 millivolt. Viscosity was 1.83 mpa. All of which were coincided with physical desire. In addition, the tests of PHGF liposomes including irritation, hemolysis, pyrogen, anomaly toxicity and hypersensibility, proved that the preparation reached the standard of intravenous injection entirely. Taking glutamic pyruvic transaminase and malondialdehyde in mice as index, studies on pharmacodynamics after hepatic injure caused by tetrachloromethane in mice indicated that GPT level (P.001) and MDA yieldment P
