In order to determine the saturated vapor pressure of colloid ed dinitrogen tetroxide,and find out its change rule with the various temperature,a testing equipment of determining satuated vapor pressure of colloid ed dinitrogen tetroxide was designed and constructed according to the principle of static testing.

为了测定胶体四氧化二氮的饱和蒸气压，找出其在不同温度条件下的变化规律，采用静态法测试原理，自行设计建立了四氧化二氮胶体饱和蒸气压的测试装置，测得了常压下液体和胶体四氧化二氮的饱和蒸气压数据，结果表明，四氧化二氮体系成胶后比成胶前的饱和蒸气压略有降低，且温度越高其差值越大。

Selection of monitoring spotsWith the consideration of energy structure in Shenyang, weather conditions , pollution levels of major atmospheric pollutants, the health effects of air pollution, and the acquirability of historical records on the air pollution, 1991 -2001 environmental quality monitoring data of Shenyang were acquired and analysed.

颗粒物样品的采集与测定(1)大气污染粉尘采样：在每个监测点设置AN-200自动空气采样器，分夏季和冬季各采样一次，每次采样时间一周，每天24小时连续采样，同时记录气温、气压和相对湿度。

Thermogravimetric analysis was extended to the measurements on vapor pressures of three n-alkanes, hexadecane, heptadecane and octadecane, on the basis of the Langmuir equation for zero-order vaporization process. The vapor pressures were calculated by two different methods, a constant-parameter one and a comparative one, from the TGA data. These results are in good agreement with the reference data calculated from the Antoine equation.

根据自由蒸发过程的Langmuir关系，将热重分析用于正十六烷、正十七烷和正十八烷等3个正构烷烃的蒸气压测定，分别采用常数法和比较法计算蒸气压，其结果与文献数据符合较好。

The expression of one-dimensional mathematical model of vertical migration of ammonia in the CRI system is:The parameters in the CRI model are determined as following: the retardarce coefficient is determined by static isothermal absorption experiment, the velocity of sewage travel through the soil column is determined by permeability test, the vertical dispersion coefficient is determined by test the electric conductivity of tracer in the dispersion experiment, the rate of nitrification and denitrification is determined by test of Baps technology.

依据单一氨氮、硝氮配水条件下的试验结果，引入多孔介质的溶质运移理论及对流-弥散方程，考虑NH4+-N在CRI系统中的运移受到对流和水动力弥散作用的影响，并吸附-解吸、硝化与反硝化3个过程，首次将配水流经CRI土柱的孔隙水流速方程与CRI土柱内发生的、以氧为约束条件的硝化、反硝化过程联系起来，建立了CRI系统一维垂向氨氮运移转化数学模型，表达式为：研究分别通过静态等温吸附实验率定了模型方程中的阻滞系数、通过渗滤试验测定了土柱中的孔隙水流速、通过测定弥散试验中示踪剂的电导率确定了纵向弥散系数、通过气压过程分离技术测定了土柱中的总硝化与反硝化反应速率常数，最后通过测定土柱沿程氧化-还原电位的方法分析氨氮在CRI系统中的运移转化机理。
