Optional shock wave generator that introduced from germany , which has the advantages in fragmentation efficiency , low noise and low cost of lithotripsy 采用引进德国技术的电磁波源发生器,具有碎石效果好,无噪声,低成本碎石的优点。
Spectrumanalyzer , oscilloscope und wave generator with the help of a soundcard and the audiotester : with the help of a high quality soundcard your pc will be an audio labour 简介:声音测试软件,配合一块高质量的声卡,使pc机成为一个声音实验室。
In meantime , the all sub - circuits are also designed and emulated carefully including error amplifier , voltage reference circuit , voltage comparator , rs type flip - flop , soft - start circuit , sawtooth - wave generator , pwm comparator , current added circuit and so on 其次对控制器内部芯片的各个模块误差放大电器、自举电流电路、电压基准源、电流求和电路、 rs触发器和驱动电路等模块进行了具体的设计和仿真的逻辑功能做了解释。
Experimental techniques for simulating cavity decoupling explosion in laboratory wear developed , which include a center initiating explosive charge designed in shape of mini - spherical with yield equivalent to 0 . 125 ~ 8 . 00gtnt , circular electromagnetic particle velocity gages and aluminum bar strain gages measurement techniques , spherical divergent stress waves generator . large amount of tamped and cavity explosion experiments had been made in granite , soil , cement mortar and water media environment , respectively 本文建立起了包括中心起爆的0 . 125 8 . 00gtnt微型球形炸药装置的研制、圆环形电磁粒子速度计及铝杆应变计测试技术和球形发散应力波实验装置等在内的实验室微型药量空腔解耦化爆模拟技术,并在花岗岩、土、水泥砂浆和水等介质中进行了大量的填实和空腔爆炸实验研究。
We have made a full theoretical analysis of the wave property and the wave parameters of the flap - type wave generator in the towing tank of our school , and confirmed that should make the factor that the performance of the wave generator give play to normally to influence . in allusion to that the old wave generator can not simulate sea wave , upgrade and transform to this system change the control computer system and install additional d / a change card , redesign the wave control interface and transmission means of control signal , give up the disk machine that can not be used , make the wave - making control voltage signal that has translated direct input the wave controller , make wave controller to make waves through servo system 对我校船模水池原有的摇板式造波系统的性能进行了理论分析,针对水池原有造波机系统模拟海浪的不足,对该系统进行升级与改造,更换了主控计算机并加装d a转换卡,重新设计了造波控制信号的接口与传输方式,舍去了原系统中现已淘汰的磁盘机,使转换后的造波控制电压信号直接输入到造波控制器中,再由造波控制器通过液压伺服系统驱动造波板进行造波。
