The results indicate: 1 closed- loop gain and open-loop gain to meet basic relationship; 2 the stability of feedback is enhanced and output resistance increased. Furthermore, the result of open-loop and closed-loop gain of theoretical calculation is consistent with simulation which is applied by EWB software, which confirmed elementary conclusions and relationships in negative-feedback amplifier quantitatively.

结果表明：闭环增益与开环增益满足基本关系式；引入负反馈后稳定性得以提高，输出电阻增大；同时使用EWB对开环与闭环增益也进行了仿真分析，结果与理论计算一致，从而定量地验证了负反馈放大电路中的结论与关系。

The Mark II Mini Cooper was first introduced back in 2006 with the Clubman following less than a year later, so these new shots depicting both of these cars with some new features is a little surprising.

马克二迷你库伯首次引入早在2006年之后的花花公子不到一年后，使这些新的球描绘这两种车的一些新功能是什么奇怪。

With brand success comes more models, and BMW has already capitalized on the Mini name in a big way with new variants such as the Clubman as well as an upcoming crossover model, and this trend is likely to continue with the introduction of a possible two-seater convertible speedster.

品牌的成功来自更多的模型，和宝马已经利用Mini的名字在一个大的方式的新变种，如花花公子，以及即将举行的交叉模式，而且这一趋势很可能会继续引入可能两双座敞篷speedster 。

And the shortages of two simplifications are pointed out.(2)A new networked PC cluster parallel computing environment is set up, and the detailed method of configuration and use is presented.

为引入有限元的并行计算技术，架构了一个微机机群并行环境，并详细给出了计算环境配置和使用方法。

But ECT technology has the following characteristics: 1 the measured capacitance and its change induced by the measured material concentration variation are very small, but the stray capacitances of co-axial screening cable and CMOS switches are relative very large, so the capacitance detecting is easily affected by the stray capacitances, 2 the electric fields in the sensors detecting region is affected by the permittivity distribution, non-uniformity of the space responsive sensitivity is very high, and the image reconstruction is undetermined.

但由于ECT技术中，首先所检测的微电容量及其因物流相含率的变化所引起的变化量很小，而由相关的连接同轴屏蔽电缆与切换CMOS开关所引入的杂散电容远远大于测量电容，微电容的测量容易受杂散电容等的影响；其次，多电极电容传感器测量区内的电场受介质分布的影响，且测量区内的空间响应灵敏度极不均衡，其影响图像重建的不确定性；其三，ECT中的图像重建，由于其是一个欠定问题的求解，在迭代求解方法中，迭代的初值影响迭代过程收敛到近似解的速度；其四，对于气/固两相流应用而言，由于ECT系统在线标定的难以实现，管壁磨损等因素的影响制约该技术应用于生产工艺中气/固两相流的长期连续检测。
