Analysis on the influence of the power converse to the double - circuit transmission lines pilot protective relaying and its corresponding measures 功率倒向对平行双回线纵联保护的影响分析及对策
The effects of the thickness , the interfacial coupling constant and the temperature on the hysteresis of the bilayer are investigated 我们考察了薄膜厚度、界面耦合强度和温度对铁电双层薄膜电滞回线的影响。
Hysteresis loop of ferromagnetic materials are measured by using surface magneto - optic kerr effect , and the kerr rotation angle is obtained 摘要用表面磁光克尔效应测量铁磁材料的磁滞回线，并求得在饱和状态下的克尔旋转角。
With the aid of phase - mode transformation , one line fault and cross line fault positions are determined in mode - domain accurately 该算法不受系统阻抗和过渡电阻的影响，并且消除了双回线间耦合的影响，可用于单回线故障和跨线故障的测距。
Each room is furnished with a bed , a desk , a chair , an air - conditioner , a telephone , a bookshelf , a chest of drawers , a lamp and an internet line 学生会馆提供早晚2餐。房间配备有床书桌椅子空调电话书架衣柜照明灯具因特网回线等。
The theory analysis and atp - emtp simulation results show the distance relay have excellent performance in detecting the double lines when one - phase ground fault take place 大量atp仿真试验证明新方法对于双回线出现的单相接地故障，具有足够的灵敏度。
In fault state , a double circuit transmission line can he decoupled into common sequence component network and differential sequence component network 由于并联电抗器的安装，直接测取双回线两端母线处的电压及线路流过的电流进行测距，必然会引起误差。
For the use of vibration protection , hysteresis loop is often applied to descript and calculate the parameters of dry friction damping characteristics of metal rubber 在振动防护领域，通常用金属橡胶阻尼元件的迟滞回线来描述金属橡胶的干摩擦阻尼特性。
The quantum effect on the hysteresis is also examined ; it is found that the quantum effect can result in the disappearance of the multi - state hysteresis 同时我们还研究了量子效应对多态电滞回线的影响，量子效应的增强会导致电滞回线由三条回线变成单个回线。
