| Abstract: | Pro ceeding from analyzing unstable phenomenon of the planar diaphragm structure of the pressure sensor in the rapid temperature changing field, the author broke free from conventional designing methods and adopted novel spherical shell sha ped diaphragm structure to overcome the unstable phenomenon.The au thor also combined this technique with a series of corresponding technical measu res to realize real time precision measurement of rapid changing pressure in th e transient temperature flow field. |
