We first prove a formula to calculate the magnetic field in the internal region of magnetized objects on the viewpoint of magnetization, and then use the formula to define the point-function demagnetizing tensor and also prove some properties of the tensor. Finally we use this formula to construct a new method to predict the induced magnetic field of naval vessels in a nonuniform applied field, and we call it 'the Magnetization Method', in which the point-function demagnetizing tensor is used.

首先证明了一个基于磁化观点的铁磁物体内部磁场强度计算公式，随后通过该公式导出了点函数去磁张量的概并证明了它的一些性质，最后利用此公式构造了一个预测非均匀外场中舰船感应磁场的新方法——磁化强度法，且在该方法中用到了点函数去磁张量。

The star calibration system, which is one of methods to calibrate precision and adjust tolerance of tracing and measuring devices in fields, has been widely applied to high precision tracing and measuring devices such as photoelectric theodolites, radars , etc.

星体标校系统是实现跟踪测量设备外场精度标校和误差调整的方法之一，广泛应用于光电经纬仪、雷达等高精度跟踪测量设备中。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
