同步脉冲

In video jargon, the sync pulses are said to be blacker than black..

在电视的专门术语中，同步脉冲被说成是比黑色的线更具有黑色性。

Characterizations of finite and recursively enumerable languages are obtained by asynchronous spiking neural P systems with extended rules.

由于在非同步模式下，考虑系统的计算时间是没有意义的，因此在非同步脉冲神经膜系统中只能定义非限制性语言。

Summary This paper analyzes the working principle and stability of a transistor mul- tivibrator operating as a frequency divider,with both sides being synchronized by the input signal.It is found that the frequency division stability of this circuit can further be increased when the multivibrator operates in the second class of oscillating condition,and that the optimum operating point is best determined from the actual base voltage changing characteristic.

本文分析了晶体管自激多谐振荡器用作双侧同步分频电路的一般理论和分频稳定性，并考虑基极电压变化规律来确定最佳分频的工作状态和运用点，同时对同步脉冲的引入问题亦作了原理性补充，还提出了振荡于第二类状态下的自激多谐振荡器可获得高稳定性的分频，以及此类双侧同步分频电路的设计方法。

When using the Sync feature it is important that the Sync pulses are spaced less than 100ms apart.

Instead of triggering on each pulse, a phase lock technique examines the relative phase between each oscillator and many of its sync pulses and adjusts oscillator frequency so that the average phase discrepancy is small.

锁相技术靠检查各振荡器和许多同步脉冲之间的相位关系来调节振荡频率，使平均相位偏差很小，而不是用每一个脉冲进行触发。

Firstly, the paper, combining the characteristic of synchronous pulse bursts and inhibition with the modified PCNN model, presents a way of finding the foveation points in the images adaptively and effectively, and simulates the human vision system. Secondly, PCNN is extended to PCNNs, based on the properties of information couple and transmission, an algorithm that is used to fuse images of the same target got by several sensors to an image is presented to simulate the human vision system. Thirdly, combining the properties of synchronous pulse bursts, capture, and transmission and competition of waves, the paper presents two ways of classification, one is an algorithm based on the properties of neuron to capture and inhibit to classify the data taking on any complex unlinear distribution robustly, the other is based on the restricted distance and modified of the former to remove the influence of inferior samples in classification; Finally, based on the accumulative difference pictures, and the forming and transmission of PCNN wave, selecting and controlling the direction of autowave by connecting the neighbouring neurons selectively, the paper presents a way to simulate the tracks of moving object and detect the moving direction.

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.
