Abstract : 　The article introduces a concept of an explosive wave energy surface density by the study of mechanical sen2 sor for measuring explosive damage in the near field. The result shows that the sensor can measure explosive breaking strength efficiently ; moreover , the sensor can be regarded as an explosive wave damage criterion for evaluation in the near
field. At the same time , mechanical sensor is compared with a piezoelectricity sensor , and the results of measurement coin2 cide in relatively further field , which shows that mechanical sensor can be used to guide project in practice.
Key words : 　mechanical sensor ; near field ; breaking strength
