运用了物理高频振动的原理，在做按摩的同时上下振动，因而产生与人手按摩相似的感觉，特设不同的按摩方式及可调节的振速，起到深层按摩的作用，分解、消耗脂肪；运动肌肉；从而达到减肥效果。
And according to real conditions has finished relative experiments . consequently , in theory the author utilizes subspace and lanczos methods to analyses , experimental data . through the comparing , find in " limiting elements calculation the different boundary can affect dynamic properties , for example , the important place of lateral vibration , vertical vibration , shrinking vibration and vertical distortion vibration in automatic frequency
在现有条件下完成了相应的部分实验，并用subspace (子空间)迭代法和lanczos (兰索斯)法在理论上对实验数据进行分析，同时与试验成果相互对照，找出不同的边界条件在有限元计算中对结构动力特性的影响，例如，侧向振动、上下振动、收缩振动及竖向扭曲振动在结构的自振频率中的主次关系。
