In general, the dipole components are located at the zero potential plane, called null plane. However, for 3D topographic mapping, many zero potential points can be detected. Instead of testing all the possible points, the proposed approach is to fit the selected zero potentials in terms of a linear plane, i.e. null plane, via least square approach.

一般来说，电偶极的位置都在零电位面上，为了取得零电位面，本研究在三度空间拓朴图映射中找出多点零电位点，然后采用最小平方法，找出一个线性平面通过这些零电位点当做零电位面。

Compared with hard-switching inverter, the soft-switching inverter's power swatches turn-on at zero voltage or zero current conditions, zero switching losses in theory, which can improve the efficiency of the system and device power density, reducing the system electromagnetic interference and ensure a brushless DC motor performance and reliability.

与硬开关逆变器相比软开关逆变器的功率开关在零电压或零电流条件下导通，理论上开关损耗为零，从而可以提高系统的效率和装置的功率密度，减小系统的电磁干扰，保证了无刷直流电机的性能和可靠性。

An ring R is said to be the middle superprime ring, if every non - zero ideal of R contains an non - zero element c, which is not middle divisor of zero.

一个环R称为中间超素环，如果它的每个非零理想都包含一个非零元素，它不是中间零因子。
