查询词典 constant field

The experiment result shows, when extra magnetic field B=0, and supply voltage VDS is constant, inequipotential potentials VHO of the nc-Si/c-Si heterojunction MAGFET are close to zero output with increasing absolute value of the gate biased voltage VGS. Adopting gate biased voltage to compensate inequipotential potentials, compared with extra compensation resistance method, could improve magnetic sensor sensitivity, when supply voltage VDS is -1.0 V, magnetic sensitivity can be improved by 18%.

实验结果表明，当外加磁场B=0时，工作电压VDS恒定时，随栅极偏置电压VGS 绝对值增加，纳米硅/单晶硅异质结MAGFET不等位电势VHO逐渐接近零位输出；采用栅极偏置电压进行不等位电势补偿较外加补偿电阻方法可以使磁传感器灵敏度得到提高，在工作电压VDS为-1.0 V时磁灵敏度约提高18%。

In these cases, some constant findings were found, those are abnormal angulation and/or connection between right hilar bronchus, right main bronchus and trachea, nonvisualization or disappearance of interlobar artery, intermediate bronchus and horizontally oriented pulmonary veins in right lower lung field. These findings can be easily explained by normal anatomy.

在此4例中我们发现一些过去文献所未记载之X光徵象；即右肺门区之支气管与右主支气管丧失直线衔接关系或虽成直线衔接但与气管成宽角度衔接，叶间动脉、中间支气管及右下肺野水平走向之肺静脉消失不见，这些所见可由正常解剖关系得到合理的解释。

This one-way wave equation fits eikonal equation and transport equation corresponding to full acoustic wave equation in travel-time and first order amplitude. According to the perturbation theory often used in inverse solution, we split the velocity field into intraformational constant velocity background and variable velocity disturbance. Then we calculate time-shift quantity of migration and amplitude correction coefficients for wavefield depth continuation in total uniform formation and each formation.
