High extent is in proper order: paramagnetism matter＞ferromagnetism matter＞diamagnetism matter. The highest values of retention rates are occurring in 0.3 T.The article summarizes the effect of magnetic field on the fermentation liquid membrane filtration process. Found that magnetizing also can increase the membrane flux and the removal rate of protein and COD.

文章从物质的磁性来源、分子间位能和外加磁场的关系，黏度、表面张力和内能的关系以及外加磁场出现多极值的原因分析等方面分析了外加磁场影响物质性能的原理，认为外加磁场对物质性能的影响在于外加磁场影响了分子的取向，从而引起了溶液中分子的重排所致。

The results were in good agreement with those from the conventional COD methods, i.e ., permanganate and dichromate ones.

将该方法用于实际水样的检测，测定结果与COD标准分析法有较好的一致性。

The comparison of monitoring COD in water with rapid monitoring method and potassium dichromate method is finished.

比较了快速测定法与国家标准方法重铬酸钾法(GB11914-89)测定化学需氧量。

Potassium dichromate was replaced by ceric sulfate as oxidant to determine the COD in this study.

采用硫酸高铈作为氧化剂来测定难降解垃圾渗滤液的COD，测定结果与重铬酸钾法进行比较。

In the calculation of COD and DO, the atmosphere oxygen resume equation and coefficient considered the molecule diffuseness and turbulence diffuseness are successfully exercised, and made a better result.

其中，COD、DO的计算中，成功的运用了本文建立的考虑了分子扩散和紊动扩散两种因素的大气复氧方程和大气复氧系数计算公式，取得较好的结果。

Since COD reduction is stoichiometrically related to methane production, the anaerobic digester performance can be easily calculated.

由于从化学论量上讲，COD的降解于甲烷产量有关，因此厌氧性消化装置的性能可以很容易地计算出来。

COD in process wastewater of ephedrine extraction is classified according to its dissolubility.

The phytoplankton diversity was restricted by environment factor such as water temperature, salinity, COD, biomass, species.

浮游植物多样性主要受水温、盐度、COD、生物量、物种数等环境因子的制约。

Almost two decades on, the cod show no sign of recovery, perhaps because new predators, such as dogfish, now dominate the waters.

也许是因为狗鲨一类新的掠食者如今统治了这片水域。

Similar as traditional activated sludge system, when the water temperature was below 4℃, sludge bacteria went into dominancy phase and metabolism stopped. All the removal of nitrogen and COD was due to membrane blockage.

与传统活性污泥系统类似，在水温低于4℃的情况下，MBR反应器内的微生物进入休眠状态，无法对水中污染物质进行分解代谢，对于氨氮和COD的去除均由膜组件的物理截留造成。

Chinese traditional virtue is humility and wariness,the compliment and praise to the others should be declination

中国人的传统美德是谦虚谨慎，对别人的恭维和夸奖应是推辞。如

We bought this house on the never-never.
