Basically, the method is developed according to sensitivity analysis. the unit volume energy criterion of weak substructures of a structure system is proposed.
在本文中提出了基于单元格能量的分析方法，这种方法基于灵敏度方法，它提出了薄弱机构的能量标准。
The sensor uses new solid material as transmission media and uses new piezoelectric material as sensitive unit, which raises the sensitivity.
传感器使用固体材料作为传感器的传播介质，用新型的压电材料作为敏感元件，提高了灵敏度。
The analysis indicates that the sensitivity on a unit mass is nearly independent of the shape of the mass block, whereas it is more dependent on the resonance frequency of that block.
分析表明：单位质量灵敏度和质量块的形状关系甚小，而和共振频率的关系较大。
