  time interleaving
A CMOS implementation of the passive equalizer that uses time interleaving is presented in this paper.
      
In the transmitter, 8 GSample/sec is achieved by time interleaving eight D/A converters, each enabled by phase shifted versions of a 1 GHz clock.
      
Time interleaving is used to achieve 8GSa/s, and the effects of the increased data converter capacitances are reduced with bond-wire inductors.
      
Therefore, using time interleaving can increase the power effectiveness as the technique reduces the clock frequency in the paths.
      


Besides the frequency selective fading in multipath channel of wireless communication, there exists the slow fading varying from 20 ms up to 100 ms due to the receiver movement and environmental change. Based on the performance analysis of DAB(Digital Audio Broadcasting) time interleaving, an improved time interleaving method is presented. The simulation results show that by increasing the frame number between the two adjacent symbols, the system's ability to resist the slow fading could be directly estimated...

Objective:To study the mechanism of Qiang Wei He Ji(QWHJ)on treatment of coronary heart disease (CHD)and angina.Methods:QW wind-evil treating recipe(WETR),QW blood circualtion promoting recipe(BCPR)and normal saline(NS)were given therough grastric infusiono different groups of rats respectively.Influence of different recipes on adrenalin-induced experimental microcirculation dysfunction of rats were observed with the following index:mesenteric blood color,state of blood flow,velocity of blood flow,recovery time of vasospasm and cross dots.Results:WETR and BCPR could both turn blood color to red,increase corss dot unmber,improve state and velocity of blood flow,decrease recovery time of vasospasm.There were significant difference in the results of WETR and BCPR groups compared with normal saline group ( P <0.05 or P <0.001).Results of BCPR group were even more significant compared with WETR group( P <0.05).Conclusion:QWHJ improve state of microcirculation and this maybe the pharmacological mechanism of the blood circulation promoting,pain relieving,vasospasm stopping and collateral dnedging gresults of QWHJ in treating CHD and angina.

There arc three concepts about time in the "Outlaws of the Marsh". The first is the North-Song Dynasty of the events; the second is the time between the later Yuan Dynasty and early Ming Dynasty of the book being written; and the third is the time of the book being read. The geography is variable with the time, which will result in misunderstanding The lower reaches of the Yellow River used to overflow and migrated once and again The towns and villages were covered by the sand and the river system and roads...

There arc three concepts about time in the "Outlaws of the Marsh". The first is the North-Song Dynasty of the events; the second is the time between the later Yuan Dynasty and early Ming Dynasty of the book being written; and the third is the time of the book being read. The geography is variable with the time, which will result in misunderstanding The lower reaches of the Yellow River used to overflow and migrated once and again The towns and villages were covered by the sand and the river system and roads in the plain were changed. The author of "Outlaws of the Marsh" was clever to write the geography vaguely. However,a few irrational journey's line might be reality in the time of the author For example, Liangshan might be the transfer station of river way and land way in the journey from Jiangzhou to Kaifeng, which conformed the state of the Yellow River and the Great Canal in the time between the later Yuan Dynasty and early Ming Dynasty, therefore the research in Chinese traditional culture and the social subject must have the realistic attitude and the scientific principle

就《水浒传》而言,至少存在3个时间概念:事件发生的北宋;作品产生的元末明初;读者所处的时代。空间与时间交织在一起,不能截然分开。如果不能充分了解空间随着时间而产生的变化,就可能引起混乱。黄河在宋元之间泛滥频繁,下游河道变化巨大,淤埋城镇村庄,改变平原水系道路。《水浒传》中不具体叙述地理位置,显示了作者的明智;而少数看似不合理的行走线路可能是真实存在的,如元末明初从江州至开封完全可以在梁山作水陆换行,这与当时黄河、运河的状况相符。因此,传统文化和人文学科的研究必须具备求真务实的科学精神。
