When network system wase stabilized,the equivalent exchange conditions of T-п and voltage source-current source were demonstrated by concept of equivalent exchange and network theorem of stability.

当网络系统达到稳定时，根据网络等效变换的概念，应用网络稳定性原理推导出了T-п形和电压源—电流源的等效变换条件，此方法概念清晰，不仅适用于线性无源网络而且适应线性有源网络，可推广于其它两端、三端或多端线性网络变换。

This is a function of the use of MCU timer generated music program code, which is a very interesting program, we can change based on the expansion program.

详细说明：这是利用单片机定时器的功能产生音乐的程序代码，这是个非常有意思的程序，大家可以在改程序的基础上实现扩展。

Best to maintain the room temperature around 20-26 ℃, regular ventilation, indoor humidity 50%-70% in favor of dilution and expectorate sputum, air is too dry, sticky mucus in the tracheal wall is not easy to leach out

室温最好保持20-26℃左右，定时通风，室内湿度50％－70％，利于痰液稀释而咳出，空气太干燥，痰液粘在气管壁上不易排出

Finally, the Fiducial inference for the parameter's functions of exponential distribution based on the type Ⅱ censoring observations is given. Simulation study shows that the Fiducial inference is quite accurate.

本文最后还讨论了指数分布在定时截尾情形下参数函数的Fiducial推断问题；并进行了模拟研究，结果表明推断精度很高。

When product life time follows exponential distribution, an approximate method of the point-estimation for the exponential distribution under multiply type-Ⅰ censoring is provided.

文中在寿命分布为指数分布时，给出寻求定时截尾寿命试验数据缺失场合下样本分布参数点估计的一种近似方法。

The results show that the microscopical pore structure of the three dimensional orthogonal woven carbon fabric structure perform is composed of body-centered cubes which arranged periodically at spaces. The net structure and shape of the pores of perform are determined by the size and proration of the fasciculus diameter, which are key factors influencing the gaseous permeability and final density of composites. Once the proration of the fasciculus diameters of different directions is determined, the trend of diversification of the permeability followed by pore rate during CVI process and the density of composites are stated, and the permeability increases with the increase of the fasciculus diameter.

研究结果表明：三维正交结构炭纤维预制体的宏观孔隙结构在空间上可以看成是由呈周期性排列的体心立方"晶胞"构成； X ， Y 和 Z 3个方向纤维束直径大小及比例关系决定三维正交结构炭纤维预制体宏观孔隙网络的结构和形状，也是决定反应气体在孔隙中的比渗透率和复合材料最终致密度的重要因素；当 X ， Y 和 Z 3个方向纤维束直径的比例关系一定时，不同预制体在CVI增密过程中比渗透率随孔隙率变化的趋势相同；复合材料的最终致密度一定；比渗透率随纤维束直径增大而略有增大。

When locked in phase and frequency, the output is high impedance and the voltage at that pin is determined by the low-pass filter capacitor.

当相位和频率锁定时，输出端为高阻态、那个脚的电压取决于低通滤波电容。

Under a certain condition, there is negative correlation between the LC50 values of pH and those of Alk to black rockfish fingerling.

可见pH一定时，随着Alk的增大，碱度对鱼的致死作用也越大；随着受试时间的延长，碱度对鱼类的毒性作用也越来越大。

Because there is fixed time counts error, therefore requires the non-periodical time.

由于定时计数存在误差，所以需要不定期调整时间。
