The study show that the frozen earth in this area is mainly silty clay. The content of the dissolvable solt is relative high,which is 12.01%, and the main salinity is NaCL and KCL. The research also revealed that frozen intensity would ascend jumpily when the water contend in the soil reached its optimization( 10.61%) and kept rising,and this phenomena got more obvious with the decrease of the temperature. Between 0C and 10C, the frozen intensity vared very obviously, when the temperature is under -10C, the variety of frozen intensity got gently, and the change is not obvious. The frozen strength was influenced by the solution thickness in the soil hole.when the thickness increased, the frozen intensity decreased.

研究表明：那曲河地区冻土区冻土主要为颗粒较细小的粉质粘土：土样易溶盐含量较高，为12.01％，主要盐分为氯化钠NaCL和氯化钾KCL；该地区冻土土内水分达到最优含水率10.61％并继续增大时，冻结强度有个跳跃式的上升，这种现象随着温度的降低而愈明显；由0℃到-10℃时，冻结强度变化十分明显，温度下降到-10℃以后，冻结强度变化趋于平缓，变化不甚明显；冻结强度受土样孔隙中盐溶液浓度的影响，盐溶液浓度增加，冻结强度减小。

The authors investigated the singular limits of stiff relaxation and dominant diffusion for general 2×2nonlinear systems of balance laws, that is,τ=o,ε→ 0, the relaxation time τtends to zero faster than the diffusion parameter ε. If there exists a priori L∞ bound that is uniformly with respect to ε for the solutionsof a system, then the solution sequence converges to the corresponding equilibrium solution of the system.

研究一般扩散占优的2×2双曲平衡律系统奇异松弛极限，用补偿紧性方法，在松弛时间τ比扩散系数ε趋于零快时，即τ=o，ε→ 0时，得到其解的整体存在性一般框架：如果上述系统的解存在对ε一致的先验L∞估计，则其解序列收敛于上述系统的对应平衡状态解。

The full space calculation model, which suits for the asymmetric structure sometimes even including air below the surface of medium, can enable simulative result to approach real one. The FDTD algorithm based on the mixed ABCs is proper to calculate the transmission line where the electromagnetic wave is transmitted in order to send electromagnetic energy along central conductor. The calculation efficiency will be raised if the PML absorbing boundary condition is set on both planes of transmitting direction and so is the MUR two-order absorbing boundary condition in the other planes.

全空间计算模型是适合所有的不对称结构的待研究体的，而且包括了介质下面的空气部分，使仿真更加的接近实验真实情况；基于MUR-PML混合吸收边界条件的时域有限差分法非常适合计算传输线这种结构，因为传输线是传送电磁波的，电磁能量主要是沿着中心导带行进，因此在两个传输端面上设置PML完全匹配层吸收边界条件，在其他面上设置MUR二阶吸收边界条件，会大大提高计算效率，而且计算结果与XFDTD仿真软件计算结果相比较，基本趋于一致。

Comparative study on two levels of population and modules of mutualspecies in the two stations demonstrates that feature index tend to diminish suchas height,tussock amplitude,size,number,density and dry weight;and thegrowth analysis index incline to increase such as RGR、ULA、chlorophyllcontent and effectiveness of plant multi-leaves of the populations and DULA、DUMR、DAGA and DRGRa of the modules;and the dynamic curves of thepopulations and the modules also tend to steadily increase along with thetemperature ascending,heat accumulation and combination between water andheat in moderate-temperature steppe from fierce fluctuation alongside naturalprecipitation in warm-temperature steppe,illustrating that the transformabletendency from increasing the numbers of tussocks and tillers in order to expandthe resource range to seize in warm-temperature steppe to steadily improve drymatter production function of the populations and the modules in moderate-temperature steppe.

两个不同热量型研究站点共有种种群与构件两个水平的比较研究表明：随纬度增加和气温降低，种群与构件高度、丛幅、大小、数量、密度和干重等特征指标趋于降低和减少，而种群RGR、ULA、叶绿素含量和植物多叶性与构件DULA、DUMR、DRGR和DRGRa等生长指标则趋于增加，种群与构件的生长动态曲线也从随天然降水而剧烈波动趋向于随气温升高、热量积累和水热配置状况而稳定增长，说明各共有种从暖温型草原区增加植物种群与构件的大小和数量以扩充资源利用范围向中温型草原稳定地提高种群与构件的干物质生产性能的方面转变的趋势；同时，物质与能量的分配也从较多地投资于繁殖器官产生大量后代以适应未来降水的不可预期变化趋向于同化系统的构建和干物质生产效能的提高以抵御低温和干旱对物种生存的威胁，充分显示出不同温度条件及其水热组合对植物种群形态结构和生长繁育模式的显著影响及其响应特征。
