The simulated results with this model match well with the results obtained by weighing lysimeter. Because there are not good stomatal models to predict the stomatal conductance, it was inputted from measured results, then the evapotranspiration rate is simulated separately for different times in a day.

模拟的结果与lysimeter的测量结果符合得比较好，但由于没有合适的气孔模型，所以模型中的气孔导度是用测定值代入的，因而模拟的蒸散量不是连续的。

At leaf scale, TJ photosynthesis model was selected and Gao stomatal conductance model was proved suitable for semi-arid region after comparing with BBL model through the parameter regression and analysis of model sensitivity.

The numerical simulation result indicates that the condition of which generated APSGD is that the AC voltage frequency is 9kHz when the electrodes configuration is determinate and the sinusoidal peak-to-peak applied voltage is about 9kV. When the AC voltage frequency is about 1MHz, the discharge pattern of SDBD is filament discharge. This results is very important for the development of SDBD.

从数值模拟的结果来看，在确定的发生器电极结构下，当电压的峰-峰值电压为9kV时，发生沿面辉光的条件是电压频率至少为9kHz，而当频率为1MHz时，沿面放电将出现丝状放电的模式，因而这一模拟结果对沿面放电发生器的研制有很重要的指导意义。

As it fell, the simulated gravity and simulated surface friction made its legs bounce and slip realistically.

当它掉下来的时候，模拟的重力和模拟的表面摩擦力会让它的腿像在现实中那样反弹和打滑。

However, there is a big discrepancy between the present simulations and experiments for laser-produced Au plasmas. Theoretical investigations on Thomson scattering were also done.

结果表明，铝盘靶的实验结果与数值模拟的结果相当一致，但金盘靶的实验结果与现有的程序模拟结果有较大差异。

Keyboard function set through waveform type,frequency,amplitude,duty cycle,and other parameters of a signal to the microprocessor 89C51 control,MAX038 generated by the various signals,In this process,four-channel signal through D/A converters have simulated voltage and current,It transported up through the analog signal amplification,it enters the frequency MAX038 coarse-IIN,fine-tuning FADJ end,the duty cycle control-DADJ.

However, making a animation looks real is not a easy job. In this thesis, we focus on the soft and flexible parts of the body. These parts are usually not easy to simulate.

然而，要做出一段很真实的动画并不容易，在我们的论文里，我们要模拟的是人体上比较柔软的部分，这些部分通常比较难模拟。

To investigate the ohmic contact of low resistance and high stability, the energy band models of n- and p-type SiC ohmic contact formation mechanism are put forward.
