- Clinical and mechanical studies progress on treatment of malignant tumour by ultralow frequency pulsed - gradient magnetic fields
半梯度磁場治療惡性腫瘤的臨床和機理研究進展 - But can keep even gradient magnetic field range strong , hall ' s component can only measurement displacement among a small circle ( usually only about 1mm )
然而，能保持均勻梯度磁場的范圍不大，霍爾元件只能小范圍(通常僅約1mm )的測量位移。 - The hore component is set on the tracking mechanical system to detect the magnetic field ' s movement . under this situation , the hore component will always keep up with the target ' s movement and keep in the magnet ' s unitary gradient magnetic field
這樣，霍爾元件慣性小、非接觸的優(yōu)點將使它在各種位移與振動的測量中發(fā)揮作用，成為一種性能優(yōu)良的位移傳感器。 - According to more effect , when the hore component is placed in a gradient field , at the same time the direction of the current is perpendicular to the direction of the voltage , then between the two parallel side face come out the hore voltage . when hore component is set in this kind of uni - gradient magnetic field and the electric current is unchanged , the voltage output of hore component will be proportional to the position of the hore component in the magnetic field . so we can use the hore component to measure the movement of hore component against magnetic field
根據(jù)霍爾效應(yīng)可知，置于磁場中的霍爾元件若電流方向與磁場方向垂直，則在霍爾元件垂直于磁場和電流方向的兩個側(cè)面將產(chǎn)生電勢，將霍爾元件置于強度隨空間位置線性變化的磁場中，且控制電流恒定，輸出就正比于霍爾元件處于磁場中的位置，因此可以用霍爾元件來測量磁場與霍爾元件間的相對位移量。 - If we want to compose in a larger area a uni - gradient magnetic field , the device will be too complicated and unfit for move . it will restrict the application of hore component in displacement measuring . in order to change this situation , in this dissertation , a kind of auto - tracking measuring system is introduced
若能在簡單磁場的條件下，通過自動跟隨系統(tǒng)驅(qū)動霍爾元件跟隨測量移動物體的位移，使霍爾元件盡可能地保持在均勻梯度磁場內(nèi)，就可以在很大程度上增加測量范圍。
