查询词典 field magnet

So,if we use common magnet and Hore component to measure the movement of the object,we can only measure in a small area. 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.

若能在简单磁场的条件下，通过自动跟随系统驱动霍尔元件跟随测量移动物体的位移，使霍尔元件尽可能地保持在均匀梯度磁场内，就可以在很大程度上增加测量范围。

Compared to other means,using Hore component to measure the displacement of object has some advantages including smaller transient response,better dynamic properties,non-contact and higher accuracy of measurement. However,the magnetic field produced by common magnet can keep the gradient unchanged only in a small area.

然而，一般磁场只可能在极小的范围内保持均匀梯度，若要求在大范围内保持均匀梯度，其磁场结构复杂、体积庞大，在很大程度上限制了霍尔元件测量位移的应用。

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.On this subject,Chen Wenxiang"s Using feedback servo mechanism to scale-up the measurement range on the shift by Hore sensor and Chen Dongjun"s Study of a kind of Hore shift sensor with feedback servo mechanism have achieve the rudimental results. It shows that using self-tracking or servo system to scale-up the measurement range of the Hore sensor is reasonable.

在这项研究工作上，陈文芗《采用反馈随动机构扩大霍尔传感器位移测量范围》、陈东军《一种带有反馈随动机构的霍尔位移传感器研究》已经取得了初步的成果，他们的成果表明采用随动机构扩大霍尔元件的测量范围是有效可行的。

In addition, staggering the joint gap between the magnets and precisely magnetizing the permanent magnet facilitate enhancing the uniformity of the magnetic field in the working region.

另外，错开磁体间安装接缝和对永磁体精确充磁能够有效提高工作区域磁场分布的均匀性。
