Through researching the mechanism of biological nitrification and denitrification and actual project application of the technology and related literature materials, the obtained results are as follows:(1) Anoxybiosis is effective to the removal of COD; after the anoxic process, BOD/COD of the outflow increases, it shows that the degradation ability of wastewater is improved; anoxybiosis is insensitive when shock loading of inflow wastewater varies greatly;(2) It is demonstrated by the operation of inoculation and cultivating that biofilm takes two weeks to succeed in cultivating on packings and the removal ratios of NH3-N and COD get 50% and 70% respectively, when gas-water ratio is 6:1, HRT is 7.3 hour, water temperature is above 15°C;(3) It is demonstrated that gas-water ratio, hydraulic loading, HRT, temperature, pH etc are important factors which influence the removal effect of pollutants, when the gas-water ratio is 6:1, hydraulic loading is about 0.38kgNH3-N/m~3.d, water temperature ranges from 15°C to 27°C, pH ranges from 7.5 to 8.0, the BIOFOR removal effect of pollutants is the best;(4) The operation indicated that, this technology has strong ability of nitrification and denitrification; it has extremely vital significance for reducing the water body eutrophication;(5) It is confirmed the feasibility and the usability of preanoxic-BIOFOR process to treat L-lactic acid production wastewater. The experiment indicated that the treatment effect of this technology is very good and also shows that the technology has many advantages, such as small volume, high treatment efficiency, good effluent quality and strong endurance to load variation, this technology is a new and economical wastewater treatment process.

Gradually, the separate sine waves have become visible. The dominant signal, corresponding to a planet with about the same mass as Jupiter but which orbits 55 Cancri A more closely than Mercury orbits the sun, was detected in 1996. Two further sine waves emerged in 2002, corresponding to one planet that has the mass of Saturn and is also orbiting more closely than Mercury, and another with four times the mass of Jupiter that is located in what would be Jupiter's orbit.

逐渐地，&正弦波&曲线出现明显的分离。1996年，科学家探测到了起支配作用的讯号，这种讯号表明发出讯号的行星与木星有着相同的质量，但它围绕恒星&55 Cancri A&运行的距离比水星围绕太阳运行的距离还要小。2002年，另外两个&正弦波&曲线被发现，它们也分别代表两颗行星：一个行星有着土星的质量，围绕恒星的距离也比水星围绕太阳的距离要小；另一个行星有着木星质量的四倍，其位置将会预计在木星的运行轨迹上。

It is clear that when the book was attached to the multifraction run and electro-optical control at run time, motor brake is frequently used for closing the case of separation action, so that, if the brake friction wheel every time suck-journeyuva or slightly slightly the lawyers'gowns so that it tends to concentrate on local contrate friction to the corresponding axis wheels, and an increase in the work of the resistance of the motor, which in turn lead to a book should be sent along to run slowly.

很较着，当书夹在独不宾运行和光电把持运行时，电机的制动器是在屡不主息呼分别离动息的环境下举行的，这样，当制动器上的摩擦轮每不宾呼分的旅程稍有不到位或稍有方向时，不离便当使其方向的部分端面摩擦到对应的轴轮上，而补充电机的工息阻力，进而引起书夹运行速率减缓。

ABSTRACTThis thesis analyzed a good many issue about operating normally and faultily on Hai-Jin-Jia 330kV extra high voltage transmission lines.

Add 200g per ton water of this product into boiler make-up water. During operation, blow-off every hour, 5-10 second each time. If the boiler has heavy scale, increase the quantity, and frequently blow-off. After 10-20 days' continuous operation, stop the boiler, open the handhole, remove the visible scale deposit to prevent conduit blockage, then, the boiler may turn into normal operation again.

按每吨水加200g药剂的比例加入锅炉补充水中即可，使用时注意排污，要求每小时排污一次，每次5～10秒，如锅炉带垢运行可加大药剂用量，勤排污，运行10～20天后应停炉，人工把脱落下的水垢清理干净，防止污垢堵塞管道，然后转入正常运行。

The results show that when the cathode humidified temperature increase, the humidification of membrane and fuel cell performance improved at lower current density, while the saturation in diffusion layer increase and the performance decreases at higher current density. Humidification of membrane and fuel cell performance improved when the anode humidified temperature increase, the saturation in diffusion layer decrease and fuel cell performance improved when the fuel cell working temperature increase, the resistance of diffusion layer decrease and the performance improved when the porosity largen. At last, the simulation results are compared with the experimental results and they are basically the same.
