Binary Logic Functions In control system applications,the binary numbers one(1)and zero(0)are represented by voltage levels,relay contact status,switch position,and so on.

二进制逻辑函数在控制系统应用中，二进制数一（1）和零（0）是由电压，继电器触点状态，开关的位置，所以on。

In the system, a finepositioning window signal generating circuit redundant, sample and hold circuit of positioning error signal using no traditional charge/discharge method but high-speed switches and operational amplifier integrators, and cross-zero detector with threshold for higher reliability, is originated by the author in this paper.

综合面伺服和扇区伺服的各自优点，设计完成了4000 TPI光刻伺服解调系统：在设计中，首创了带冗余的精定位窗口信号生成电路，采用高速模拟开关和运放积分电路代替传统的电容充放电法，以完成精定位位置误差信号的平均与采样保持，使用带阈值的过零检测电路提高过道脉冲的可靠性。

The results of the research show that self synchronization closed loop control system through detecting the position of zero value of rotating EMF is new and feasible. In principle it solves the problem how to obtain the accurate rotor position of a step, motor from motor parameters. In design it makes the system simple and practical.

研究结果表明，本文研究的永磁感应子式步进电动机自同步闭环系统在原理上，通过旋转电势过零检测解决了能否利用电机参数获得准确的位置控制与自同步运行问题；在方法上采用数字信号逻辑辩识增强了系统的稳定性，解决了系统实现能否简单实用的问题。

Jupiter has a sidereal period (its movement with respect to the "fixed" stars) of 11 years, 314 days, and 839 minutes, so in nearly 12 years it is back into conjunction with those stars from which it began its orbit.

木星有一个恒星周期（它的移动与"固定的"星星相关），是11年零314天839分，因此从它的轨道开始，差不多12年的时间，回到了与那些星星关联的位置上。

Both the mass balance and snow line respond sensitively to the global warming.It is infrequent that a large negative mass balance of glacier in the Central Ti...

物质平衡出现较大的负值和零平衡线位置升高的状况，强烈反映了扎当冰川对气候变暖过程的响应。

the fast transposition algorithm to sparse matrix expressed by triple list is introduced.this algorithm needs to determine the position in the transposed matrix position of the first element which is not equal to zero in the original matrix each row,it uses two arrays as auxiliary space.in order to reduce the auxiliary space which the algorithm needed,an improvement is made through introducing two simple variables.the improved algorithm saves a half auxiliary space compared to the original algorithm at the same time complexity.

摘 要：介绍基于三元组表表示的稀疏矩阵的快速转置算法，此算法在转置前需要先确定原矩阵中各列第一个非零元在转置矩阵中的位置，在此使用2个数组作为辅助空间，为了减少算法所需的辅助空间，通过引入2个简单变量提出一种改进算法。该改进算法在时间复杂度保持不变的情况下，空间复杂度比原算法节省一半。

If nothing is found it returns zero. The Delphi library function does basically the same thing

这个函数搜索一个字符串中的字符，并且返回发现的位置，如果没有发现则返回零。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
