到差

Adjustment of center distance or use of an idler pulley is necessary for wear and stretch compensation.

缺点包括：由于皮带的滑差和拉紧，角速度比不一定是常数或等于滑轮直径的比率；热量会不断增加；速度限制为每秒35米；动力传送限制为370千瓦；工作温度通常限制为-35℃到85℃；必须调节中心矩或使用导轮来补偿磨损和伸长。

The traditional method is that the impulse response of filter can be gotten by optimization under the perfect reconstruction condition.

传统的研究方法是在满足滤波器组完全重构的情况下通过寻优的方法得到滤波器的冲击响应，所得到的滤波器性能较差。

When I wrote last, I was in bad spirits.

当我写到最后时，我的情绪极差。

It implies that the calculation of movements of mobile cells is not accurate enough, that must affects the mass exchange between the mobile cells and immobile cells. Furthermore, because the value of concentration be calculated is always at center of an element and the finite difference grid is fixed, which may gives rise to numerical dispersion, especially when the steps of space are injudiciously selected.

另一方面，颗粒的位置直接影响到其所含各种成分的质量变化，这将在一定程度上影响最终各种成分的浓度计算精度，而且，该算法最终统计各种成分的浓度时，所用的窗口也是已有的固定的有限差分网格，当网格选择不合适时，有可能产生人工数值弥散。

These two pairs exhibit different offsets and bias currents, so when the applied input common-mode voltage changes, the AMPLIFIER input offset voltage and input bias current does also.

由于这两个差分对有不同的失调电流和偏置电流，因此加到输入共模电压变化，放大器的输入偏置电压和输入偏压电流也跟着改变。

Acted by taper-face component of centrifugal force together with scroll conveyor,the cake moves interruptedly toward the bi end of the screen-bowl and is discharged out of the screen-bowl,and then out of the machine through a discharging tank.

电机带动转鼓及同心安装的输料螺旋，以一定的差速同向高速旋转，物料由进料管连续引入，均匀分布到转鼓底段滤网壁上，在离心力作用下，液相物穿过滤网和转鼓内形成滤渣，滤渣在离心力的锥面分力和输料螺旋的共同作用下，连续不断地向转鼓大端移动排出转鼓，经卸料槽排出机外。

The constitutive equation between current density vector and electric field strength vector is tranformed into s-domain by the principle of Laplace transform,and the inverse Laplace transform is adopted for the explicit equations between them in time-domain. Finally through exponential time stepping,the FDTD iteration equations are obtained,which can be easily solved in discrete-time-domain.

该方法是将电流密度矢量与电场强度矢量之间的本构方程基于拉普拉斯变换原理转到复频域，然后再逆变换到时域得到它们之间显式的方程，最后再结合指数差分，得到离散时域的显式的FDTD迭代方程，解决了本构方程中电流密度矢量的分量相互耦合而不易直接离散的困难。

2The speed of creating random series used irrational fraction arithmetic was faster than that of multiplicative congruence arithmetic. The correlative value of random series almost was zero.(3) Regarding not harm the images quality as the premise, the speed of FM screening was heightened.

主要结论：利用所建立的条件半色调函数进行图像加网，操作简单、控制精确，使发生阶调不连续处的密度差平均减少到0.01275，明显改善了调幅加网印品的质量；(2)无理数取尾法产生随机数的速度快，数列间几乎没有相关性；(3)在不损失图像质量的前提下，提高了调频加网的输出速度。

Then applying the second development tool of AUTOCAD, Visual LISP to scheme out the programs of plotting the network's systems drawing and the water isobar. Consequently, the whole set design from the node outflow distributing to plotting the network's systems drawing and the water isobar is completed.

然后应用AUTOCAD二次开发工具Visual LISP编写出绘制管网系统图程序和绘制等水压线图程序，在AUTOCAD平台上将平差或优化的结果快速成图，从而完成从节点流量开始到管网优化直至绘出给水管网系统图和等水压线图的一整套设计。

The calculation of urban water supply system is relative complicated in consideration of network s modeling, node demand calculation, initial flow distribution, forming of correlative matrix, universal programming, and drawing method of isopiestic line .

城市给水管网计算是一个较复杂的系统，从管网的建模、节点流量的计算、初始流量的分配、各相关矩阵的自动生成、具有通用性的平差计算到管网图形和等压线的绘制，需要考虑各种相关因素的影响。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
