The main factors influencing the duration of preferential flow are the duration and the amount of rainfall. The duration of preferential flow is very evidently positively related to the duration of rainfall, and evidently positively related to the amount of rainfall. The main factor influencing the peak of preferential flow is the amount of rainfall, which is evidently positively related to the peak of preferential flow. The soil characteristics of different soil layers are very different, which induced the lateral preferential flow.

3降雨和土壤物理特性是影响优先流的重要因子，影响优先流流量的主要降雨因子是降雨总量，两者呈现出极显著的正相关关系；影响优先流历时的主要降雨因子是降雨历时和降雨总量，优先流历时与降雨历时为极显著正相关关系，与降雨总量为显著正相关关系；影响优先流峰值流量的主要降雨因子是降雨总量，两者为显著正相关关系。

The result also showed the psychological support can remarkably boost prentices' organizational commitment, but the function on job performance was divided into direct effect and indirect effect, namely the organizational commitment had the mediation effect to the relationship between psychological support and job performance. Besides, the career support had feeble direct effect on prentices' turnover intention, and the psychological support worked on prentices' turnover intention totally via the organizational commitment.

结构方程模型检验的结果显示，师徒关系中的职业支持和心理支持都对徒弟的工作绩效存在着显著的正面影响，其中职业支持对徒弟工作绩效的直接影响作用更大；心理支持对徒弟的组织承诺有显著的预测作用，而对徒弟的工作绩效的作用，一部分是直接效应，另一部分则是通过组织承诺来实施的；职业支持对徒弟的离职意愿只存在着薄弱的直接效应，心理支持则是完全通过影响徒弟的组织承诺来影响徒弟的离职倾向。

First, the effects of magnetic RAM relaxation time and the rise-time of incident pulse signal on reflection signal are discussed, the relationship between the rise-time of incident pulse and relaxation time based on the energy of reflection signal is revealed. Then, the effects of magnetic hysteric, susceptibilities and saturation upon reflection signal are analyzed, the results reveal the reflection of RAM target and UWB signal design. In the meantime, dielectric relaxation time effect about dielectric RAM target is analyzed simply, and the effects of relaxation time and the width of incident pulse upon reflection signal are probed. Finally, a few RAM targets are measured in the chamber using the impulse radar experiment system which is developed by the team of anti-stealth impulse radar on Department of Electrical Engineering, National University of Defense Technology. The experimental results show the similarity of the rule of echos with the theory. From the compared results of different tagets, we concluded, compared with 15% wideband sinusoidal signal, the impulse signal has increased 10～12dB energy from the same loaded RAM target; this, in turn, shows the nonlinear effects of RAM to the echoes, and the potentiality of the impulse signal to RAM targets.

Result It was confirmed as a reasonable population when the total stem number of wheat in reviving stage was lower than the mature spike number, the shuttle-shaped plant form at the stage of maximal population, and the leaf area coefficient in flowering stage was 4. Soil fertility had significant influence on the growth of wheat stems and leaves at early stage and had certain influence at middle-late stage. Density influenced the growth of stems and leaves before the formation of the largest population, while it had little effect after flowering.
