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。

The game lasted 87 minutes and Novara started with Skowronska outside hitter, Berg, Osmokrovic and Valeskinha on the wing, Paggi and Anzanello middleblockers and Cardullo libero.

比赛进行了87分钟，在首发阵容中，Skowronska担任外场攻击手，Berg， Osmokrovic and Valeskinha在两翼策应， Paggi and Anzanello在中场堵防，Cardullo为自由人。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
