摘要］ 目的评价规范流动采血车消毒灭菌管理的效果。方法对流动采血车内的空气、物表在规范消毒灭菌管理前后细菌培养数量的统计对比。结果规范管理前车内空气细菌总数超标率达41.67%，物表达20.83%。而规范管理后车内空气细菌超标率是4.17%，物表细菌超标率是0，差异有统计学意义。结论对流动采血车实施规范有效的消毒灭菌管理，务实消毒灭菌措施，对保证血液质量和采血安全具有重要的意义。

Aldrin at concentrations higher than 40 μg/L decreased life expectancy at birth of F1 generation of the cladoceran, that at 20 μg/L and 80-640 μg/L decreased net reproduction rate, that at 320 and 640 μg/L shortened generation time, and that at all the concentrations decreased intrinsic rate of population increase. Aldrin at 160-640 μg/L shortened life expectancy at birth and generation time of F2 generation of the cladoceran, that at 160 and 640 μg/L decreased net reproduction rate, but that at all the concentrations except for 40 and 320 μg/L increased intrinsic rate of population increase.

浓度高于40μg/L的艾氏剂使多刺裸腹溞F1代的生命期望显著缩短，20μg/L和80~640μg/L的艾试剂使F1代的净生殖率显著降低，320μg/L和640μg/L的艾氏剂使F1代的世代时间显著缩短，所有浓度的艾试剂均使F1代的种群内禀增长率显著降低。160~640μg/L的艾氏剂使多刺裸腹溞F2代的生命期望和世代时间显著缩短，160μg/L和640μg/L的艾氏剂使F2代的净生殖率显著降低；除40和320μg/L外，所有浓度的艾试剂均显著提高了F2代的种群内禀增长率。

The waste combustion in the waste bed and the impacts of the waste burning efficiency are complex. In order to solve this problem, the method of numerical simulation has been adopted to simulate waste combustion, and calculate the mass loss rate, moisture evaporation, volatile release, char burning rate. Used the total flow rate of primary air between 50～1 000 Nm3/min to calculate the mass loss, excess air coefficient of waste bed, components of the gas. Calculated results show that the burning efficiency is higher when the total flow rate of primary air is at 517.47～632.09 Nm3/min .

针对垃圾焚烧炉床层内垃圾燃烧过程复杂性及影响垃圾燃烧效率因素多的问题，运用数值仿真方法对某垃圾焚烧炉床层垃圾燃烧进行了模拟，获得了垃圾质量流失速率、水分蒸发速率、挥发分释放速率、焦炭燃烧速率和烟气的温度；并在50～1 000 Nm3/min范围内改变一次风流量，获得了床层质量流失比值、过剩空气系数和烟气中各组分的质量百分比含量。

Therefore, we studied two levels of biochemistry processing water leakage again in turn after the ozone tower, the ceramic filter the tower and the activated charcoal tower union depth processing craft again, this place principle craft its COD remove rate was 72.8%, anionic surfactant medicinal preparation remove rate was 90.9%, petroleum class remove rate was 78.8%, the total phosphorus and total nitrogen remove rate separately was 73.8% and 82.7%, the final water leakage might directly use in the city afforests, flushes the restroom, eliminates and washes the vehicle and so on, had the good environment, the society and the economic efficiency.

It showed that the propane recovery rate of new process would be 23%~27% higher than that of cryogen refrigeration process at the same refrigeration temperature. To increase the absorption tower pressure appropriately was good to improve the propane recovery rate. However, the choice of pressure must take the pressure of the feed natural gas and product gas into account together. The flow rate of absorbent had great effect on propane recovery rate and tower heat load.
