In the present study a numerical model developed by Lynett and Liu （2002） is modified to include density difference in a stratified two-layer fluid in a three-dimensional internal wave domain. The internal solitary wave （ISW） in the model is assumed to be weakly nonlinear and weakly dispersive, and the viscosity effects at all boundaries are ignored. The governing equations based on the Navier-Stokes and Euler equations are solved for internal solitary wave propagation over variable seabed topography. Theoretical formulations are established, from which analytical solutions are obtained, in addition to numerical results. Wave profiles from previous experimental studies are compared with the numerical results from the present analytical solutions. Numerical models developed on the basis of the present analytical solutions are better than those developed by Lynett and Liu （2002）. The results of numerical modeling agree well with the experimental data.

大理茶(Camellia taliensis)是茶的重要野生近缘种，是茶资源的重要组成部分，研究大理茶群体的遗传多样性和亲缘关系，对科学保护和合理利用大理茶种质资源至关重要。本研究应用SSR标记技术对澜沧江流域5个州市共45份大理茶种和5份普洱茶(C. sinensis var. assamica)种的种质资源进行遗传多样性和亲缘关系分析。结果显示，15对有效引物共检测到55个多态性位点，每对引物平均扩增3.67个位点；大理茶资源的平均期望杂合度(epected heterozygosity, He)为0.346；多态信息含量(polymorphism information content, PIC)变化范围是0.024～0.661，平均值为0.381；香农指数变化范围是0.067～1.321，平均值为0.669；多态性引物比例为60.0%，多态性引物占有效引物的比例为75.0%。聚类分析结果显示，澜沧江流域大理茶树种质分类与地理区域具有相关性，地理位置较远的大理茶树居群间的遗传距离较远，但居群内遗传距离较近。以上结果表明，澜沧江流域大理茶资源具有中等遗传多样性和中等丰富度。本研究为大理茶种质资源的保护开发及遗传图谱构建提供参考。

This study uses the smart phone with the Android system to construct a cloud-side smart switch system in the client-server architecture with the Android open platform system, using microprocessors(MCU 16F690) as the thermostat controller and combined with Raspberry Pi. The computing technology extends the control of the constant temperature from the local to the cloud, allowing the user to view the temperature status recorded by the cloud server using the smart phone application(App) or web browser. It can even remotely control the heating power of the smart switch for the heating device in the Internet control environment and use the proportional-integral-derivative(PID) control and the pulse-width modulation(PWM) technology to achieve intelligent constant temperature *** proposed control system uses the expert PID control as the core to calculate the duty cycle of the PWM signal to control the power output of the smart switch for the constant temperature water tank. The experiment results verify the effectiveness of the proposed system.
