hall electromotive force meaning in Chinese

霍耳电动势

In the hall effect , hall electromotive force is not only related to the current density , magnetic field and the distance of the poles , but also to hall coefficient directly
据知,霍耳效应中输出的霍耳电动势除了跟输入的电流强度、磁场强度及输出电极的间距有关外,还与霍耳系数成正比。
The semiconductor material has selective adsorption to the gas that changes the electronic concentration which also raises hail coefficient corresponding changes in the export of hall electromotive force
这种新型传感器不仅可以根据需要输出几毫伏至几十毫伏甚至几百毫伏的直流电压，而且具有其它半导体传感器所没有的优点无需另外加热。
Semiconductor materials was laid on the base , and the corresponding electrode was lead to . the semiconductor material has selective adsorption to the gas that changes the electronic concentration which also raises hall coefficient , corresponding changes the export of hall electromotive force , so the gas sensors which is based on hall effect was made
当我们把半导体材料涂敷到基片上,并引出相应的电极,由于气敏材料对个别气体有选择的吸附特性从而改变了材料中的电子浓度,也就引起了霍耳系数的相应变化,输出的霍耳电动势也跟着变化,就制成了基于霍耳效应的气敏传感器。
