Methods With the aid of discontiguous diagnostic technology and method of accumulated damage using accelerated aging or heat air oven, the aging isotherms for void content versus aging time were determined. According to the principle of time temperature equivalence the viscoelastic master curve for the prediction of service life were obtained. Results and Conclusion The service life of HMX CMDB solid rocket propellant grain were obtained. Because the critical storage life is measured, the accuracy of predicting the service life of the grain has been increased greatly.展开更多

Methods Based on randoming and multi-central clinical trial principle, the included 276 cases were randomized into experimental group （138 cases） and control group （138 cases） in statistics. Electric acupuncture on Dazhui（大椎 GV14） was applied in experimental group and the injection with antondine was in control group. The immediate antipyretic and clinical therapeutic effects were observed in 24 h. Results The body temperatures at different times in experimental group were all lower than those in control group after treatment （P〈 0.01 ）. The scores of relevant symptoms in 3- 24 h after treatment were lower than those in control group （P〈0.05）. The response time （1.42± 1.79） h in experimental group was shorter than that （3.44±5.10） h in control group （P〈0.05）. The response times for chills, soreness of limbs, headach and sweating in experimental group were shorter than those in control group （P〈0. 01 ）. The recovery times for chills and headache in experimental group were shorter than those in control group （P〈0.05）. The systematic therapeutic effects were different significantly between two groups in 24 h （P〈0.05）. Conclusion Acupuncture on Dazhui（大椎 GV14） had achieved definite effects on treatment for high fever in common cold. It released remarkably chills, soreness of limbs, headache and sweating and improved the systematic therapeutic effects on common cold.展开更多

The peculiar tripartite entangled state shares features of the GHZ and 14/ state simultaneously. The photon-numberdependent parts in the effective Hamiltonian are canceled with the assistance of a strong classical field, thus the scheme is insensitive to both the thermal field and the cavity decay. The only thing one needs to do is to modulate the interaction time only once.展开更多

Then temperature is constant, the solution of the black hole is obtained within a cavity, that is, the solution of the spacetime after considering the radiation of the black hole. Therefore, we derive that the location of the black hole horizon and specific heat are the functions of temperature and the radius of the cavity.Corrections to entropy also are related to the radius of the cavity. Through calculation, we obtain conditions of taking the value of the cavity's radius. We provide a new way for studying the corrections of complicated spacetimes.展开更多
