EWB做的多功能数字钟 由振荡器输出稳定的高频脉冲信号作为时间基准，经分频器输出标准的秒脉冲，秒计数器满60向分计数器进位，分计数器满60向小时计数器进位，小时计数器按“12翻1”规律计数，计数器经译码器送到显示器；计数出现误差可用校时电路进行校时、校分、校秒， 可发挥部分：使闹钟具有可整点报时与定时闹钟的功能。 -EWB done by the multi-function digital clock oscillator output stable high frequency pulse signal as a time reference. Frequency Divider output by the standards of seconds pulse, aged 60 seconds to counter-counter rounding, Counter-to-60-hour counter rounding, by the Counter-hour "12 over a" law count, Counter by the decoder to display; Counting errors school circuit can be used for schools, school hours, school seconds to play : The alarm clock can be made with whole point regular alarm clock and timer functions.

笔者首先提出了煤岩变形破裂过程电磁辐射与应力耦合的概念,然后在实验研究、理论分析和数值模拟的基础上从力电耦合的角度研究了煤岩冲击矿压预测的电磁辐射法(ＥＭＥ)。研究结果表明:ＦＬＡＣ3Ｄ方法能对矿山巷道掘进过程煤岩内部应力场进行有效的数值模拟 电磁辐射信号主要来源于应力集中区,在场点监测到的电磁辐射信号主要是应力集中区煤岩变形破裂过程产生的 ＥＭＥ信号呈现出与煤岩内部应力变化相同的规律 利用力电耦合方法研究煤岩冲击矿压电磁辐射预测法是可行的。笔者最后还对未来煤岩冲击矿压电磁辐射预测法的研究进行了展望。-first author of coal and rock deformation and fracture process of electromagnetic radiation coupled with the concept of stress, then the experimental research, theoretical analysis and numerical simulations on the basis of Congli coupling angle of coal and rock rockburst forecast of electromagnetic radiation (EME). The results showed : FLAC3D method to mine tunneling process of coal and rock internal stress effective numerical simulation of electromagnetic radiation signal comes mainly from the stress concentration areas, the monitoring point to the presence of electromagnetic radiation signal is mainly concentrated stress coal rock deformation and fracture process of EME signal showing the internal rock and coal Stress changes in the s

catia Script generated in VB. Very usefull for catia users. This Macro Scans a Product Structure for deactivated (useless) elements. Once a deactivated Part is found, it s activated intermediately for a remove operation following immediately. This action done by the Macro cannot be undone in some cases.-catia Script generated in VB. Very usefull for catia users. This Macro Scans a Product Structure for deactivated (useless) elements.
