To counter the characteristic of suppress jamming and center of mass jamming, this paper establishes the models of noise jamming, signal power attenuation and center of mass jamming.
针对压制干扰和质心干扰的特点，分别建立了噪声干扰模型、信号功率衰减模型和质心干扰模型。

In other words, the 'force' appears to adjust its strength automatically to match the mass of the object, thus always producing the acceleration characteristic of the location.
Taking into account the convenience in operating and the characteristic of mass datas, the design has friendly user's interfaces and flexible operation and concise and efficient data storage.
