This paper introduces the method of ultrasonic testing of gas cabinet sheet by using
A new method for Synthetic aperture radar(SAR) image denoising is proposed.The prior information of speckle statistical model can be exploited to judge its distribution.The basis of SAR image can be e
We propose a class of Rate-compatible(RC) Low-density parity-check(LDPC) codes with a very wide range of code rates. To widen the range of rates, we have develo
The last decade has witnessed a rapid growth in wireless communications technology, and as a result the demand for spectrum resources increased rapidly.Unfortun

Due to uncertain network connectivity, efficiently data forwarding in Mobile social networks(MSNs)becomes challenging. To conquer the problem, an Efficient data
目的 探讨用去势方法研究雌激素影响眼部疾病的可行性以及雌激素对视网膜血管渗漏的影响.方法健康成熟的雌性SD大鼠22只,随机分为实验组和对照组.实验组雌性SD大鼠用去势方法降低体内雌激素水平;对照组用假去势方法,不影响雌激素水平.手术效果用阴道上皮涂片方法证实.用光动力诱导方法建立视网膜静脉阻塞模型,用分光光度计测量视网膜伊文思蓝渗漏量.结果实验组大鼠阴道上皮成熟值降低明显(t=21.008,P=0
《素问》说:饮入与胃,游溢精气,上输于脾,脾气散精,上归于肺.《经脉别论》说:“肺主气为胃行其津液者也.”这就是胃和脾的关系.胃主腐熟水谷,脾主运化水谷,输布津液,二者分工
