In order to fully exploit the potential of the Flare plate solar collector and the low temperature water source pump in Sitsang, the simulation model of Solar assisted heat of low temperature water source pump system is developed in this paper. Using this simulation procedure, the designer can predict the dynamic characteristic of the system at the design phase.

为了使太阳能低温水源热泵辅助供暖系统可以在西藏地区充分发挥水源热泵和平板集热器的潜力，本文采用matlab的simulink仿真技术对该系统进行建模，通过模拟来预测该太阳能系统系统的运行情况，可以使设计人员，在设计阶段可以对该系统的动态特性有一个较全面的了解。

To investigate the responding behavior of denitrifying bacteria to different carbon source (i.e. methanol, ethanol, sodium acetate, sodium propionate, glucose, domestic wastewater and endogenous carbon source), several batch experiments using the sludge from the Carrousel oxidation ditch were carried out at 15.4℃±0.8℃.

为了研究低温环境下反硝化细菌对各种碳源的直接反应，利用Carrousel氧化沟系统的活性污泥，以甲醇、乙醇、乙酸钠、丙酸钠、葡萄糖、生活污水及内源物质为碳源，在15.4℃±0.8℃低温状态下开展序批式缺氧反硝化试验。

The Miyun metre-wave aperture synthesis radioteleseope, working at frequency of 232 MHz, consists of: an E-W array of 28 elements each of 9 m aperture. 192 baselines are effected with a full coverage of U-V plane (Fig. 2). The longest baseline is 1,164 m, This instrument is designed for source survey and detection of peculiar source in north declinations.

密云米波综合孔径射电望远镜工作在232MHz，由28面直径9米的东-西天线阵组成，天线阵全长1164米，u-v平面覆盖完整，适于进行北赤纬天区射电源普查及特殊源搜索。2×12小时观测得&热噪音限制&灵敏度0.05Jy，综合方向束3′。8×3′。8cscδ，视场8°×8°，可以在两年以内完成δ≥+30°天区的普查，并开展选区监测。

Administrative control: Carries on the appraisal to the entire factory clean water used, the control uses the water volume The formulation procedure guarantees the clean water used at will not to discharge The factory will have the latent risk after the appraisal the source of pollution to divide into two parts, after because the factory all cleans waste water content will have the harm matter all will be same:Methyl ethyl ketone, peroxidation armor second grade alkone, styrene, MMA, therefore will possess the washes with pool and washes the eye to treat as a source of pollution, and the suggestion will make the improvement with the identical plan.

行政控制：对全厂清洁用水进行评估，控制用水量。制定程序以确保清洁用水不被随意排放。工厂通过评估后将有潜在风险的污染源分为两个部分，因为工厂所有的清洗后的废水内含有的危害物质都是一样的：丁酮、过氧化甲乙酮、苯乙烯、MMA，所以将所有清洗池和洗眼器当作一个污染源，并建议用同一个方案去进行改进。

The device comprises further means to delimit the release time of the luminous energy source to the length of time being necessary for a reading or a reading/writing of the label, allowing to delimit temperature rises due to losses of the luminous energy source and allowing, therfore, a sufficiently highfunctioning autonomy.

该能量传递器还有一个限定装置用以将光能源发光的时间限定到读取或读／写标牌所需要的时间，从而限定因光能源损失引起的温升，进而充分提高工作过程的自动化。
