The blackbody cavity emissivity is a primary parameter of blackbody source. The measurement of blackbody cavity emissivity could verify the design value of cavity emissivity. A determination of graphite blackbody cavity emissivity by reflectance measurement is presented. The measuring equipment include a He-Ne laser, laser power stabilizer, integrating sphere, Si photoelectric detector, gray reflectance...
In the study presented here, we first evaluated effect of CDDP on liver cancer cells SMMC-7721 apoptosis and motility capacity. Then, we evaluate inhibitory effect of CDDP on tumour growth and its possible molecular mechanism in liver cancer mice model. Results showed that the apoptosis rate of cells decreased with increasing CDDP. Analysis of the effect of the CDDP on cell cycle was performed by...
In this paper, a secure Content Protection Secure Management Scheme about electronic documents (named CPSec EDMS) will be proposed, in which the architecture, key technology and authorization protocol, security analysis of CPSec EDMS will be discussed. To prevent document leakage, the client of CPSec EDMS adopts transparent encryption technology based on filter driver, in which the client encrypts...
Liaoning Province is insufficient in water resources, and with the gradually increasing process of the urbanization, the degree of water resources insufficiency is exacerbating by degrees. This paper obtains the specialty of short duration storm through analyzing the years of rain data and the seriously harmful storm with picking up Shenyang as the researching object, and finally gets frequency curve...
It makes diagnosis of induce motor very complex that itpsilas fault omens and feature is non-linear. It is more difficult to get earlier period fault information and realize function reflection between information and running state. As the knowledge limitation and parameter change in running of induce motor, the gray prediction combined with the nerve network is used to predict feature parameter and...
