查询词典 unit character

The status quo of high-resolution data acquisition system is discussed and by studying the character of high-resolution seismic exploration and seismic signal, the theoretical models and character of each unit are gained. This paper point out that under 1000 meter's depth where petroleum is embedded the IDR of central controlled seismic instrument and telemetricseismic instrument are lower than 70dB which can't meet the needs of high-resolution seismic exploration.

文章论述了当代高分辨率地震数据采集系统的现状，对高分辨率地震勘探及地震信号特点进行了研究，得出了高分辨率地震勘探数据采集系统的理论模型和各功能单元的理论特性，指出在石油与天然气埋藏的千米以下的地层，集中式数字地震仪和24位遥测地震仪的瞬时动态范围均不超过70dB，远远满足不了高分辨率地震勘探的需要。

Based on varying process of generator terminal parameters after excitation fault, shortages of excitation protective principle of static stability boundary and asynchronous impedance boundary are analyzed. It proposed that excitation fault research relates to large-disturbance stability. Because dynamic power-angle character of generator after excitation fault is non-sinusoidal, there are differences between dynamic power-angle character and static state power-angle character. So it isn't ideal to protective operation result based on small-disturbance stability and static stability boundary criterion. At the same time, it proposed that asynchronous boundary impedance criterion is a constant reactive power circle moving adown j Xd′. It can ensure complete loss-of-excitation generator measuring impedance enter into the circle, but can't ensure the other condition measuring impedance including impossible losing synchronism enter. So loss-of-excitation protection would be maloperation when system voltage drops short and recovers or generator rejects load.③Based on stability principle, it puts forward setting conditions and calculation method of generator loss-of-excitation protection by direct measuring power-angle.

以励磁故障后发电机端的相关参数的变化为基础，通过对以静稳定边界和异步阻抗边界作判据的两类三种现行励磁保护在原理上存在的缺陷分析，发现：励磁故障是一个大干扰稳定性问题，励磁故障后的发电机的动态功角特性与静态功角特性有很大的差异，已远非正弦曲线，因此基于小干扰稳定性原理、以静稳定边界作判据的保护必然动作不理想；异步边界阻抗判据是一个下移j Xd′的等无功阻抗圆，它可以保证完全失磁后的发电机测量阻抗能进入该阻抗圆，但不能保证完全失磁之外的其它状态不会进入该阻抗圆，因此在系统电压短时下降或发电机突然甩负荷等情况下可能启动该保护使之误动。

The system frame and workflow of our LPR System are introduced. Some problems and two of our proposed character recognition methods, i.e. method based on PCA-LSM for limited Chinese character recognition and method based on structural feature analysis for alphabetic and digital character recognition, are addressed in full details.

文中介绍了该系统的结构及工作流程，以及两种字符的识别方法：基于PCA-LSM的有限中文字符识别方法和基于结构特征分析的字母及数字字符识别方法。

Has a proposal during two durations receives the attention, is actually that should restore the traditional character, I thought that now the fait accomplice is so, I acknowledged in the past simplified character time has some wants its alphabetization this kind of intention, but we cannot neglect to other question, it really has other goal is its popularization, indeed this simplified character also complied with simplification of Chinese characters this kind of tidal current, is the folk folk simplification, the people are must simplify it, must universalize, popularization.

恢复繁体字的风波还能持续多久？在两会期间有一个提案是备受关注，那就是究竟该不该恢复繁体字，我觉得现在既成事实是如此，我承认当年简体字的时候是有一些想把它拼音化的这样一个意图，但是我们不能忽略到另外一个问题，它的确有另外一个目的是把它通俗化，的确这个简体字也顺应了汉字简化的这种潮流，就是民间的民间简化，人们就是要把它简化，要普及化，通俗化。
