The experimental results indicate that, over a ranger of tube side Reynolds number and Prandtl number (Re=4000~20000, Pr=6~7.5), the internal Nusselt number and friction factor of spiral-flat tube increased by 30%-150% and 20%-50% respectively compared with smooth tube at the same Re and Pr. The value of friction factor decreases with increasing the value of B/A as well as increasing that of S/de, and the same phenomena can also be observed for Nusselt number.

This Program Project is composed of five projects and an administrative core unit. The specific aims of Project 1 are to study the roles of SPE B, SPE A, M protein and NADase to correlate with bacterial virulence and disease severity in different clinical spectra of GAS infections. We will also study the pathogenic factors of a unique virulent clone of Ml strain caused dominant invasiue GAS disease in Taiwan in the past two years. The effects of penicillin and clindamycin on the production of SPE A and SPE B will also be determined.

现在社会压力太大了，前几天我上网看现在大多数人也都和你想的一样，我的那个想法估计也就只是梦想了，在现实社会中还是会低头的，去找个高新高责任的工作努力吧，在社会的大浪里磨砺自己吧，那祝你找到一个称心的工作啊 B：现在像我们这样的年轻人想找高新高责任的工作已经成为一个趋势了，来自各方面的压力太大了，没有一份高薪的工作生活都是问题啊，我还是赶快去招聘会了，高新高责任的工作有人想找还找不上呢 A：好的，祝你好运，拜拜 B：拜拜

It is concluded that the studies on effects of UV-B radiation on plants and ecosystems will be intensified; and signal transduction, molecular level mechanism and the combination effects of UV-B with other factors will be the new hotpots in the future.

根据近5年的研究进展，推断在今后一段时间内，有关增强UV-B辐射对植物和生态系统影响的研究还会加强，信号转导、分子水平机理以及增强UV-B辐射与其它因子的复合作用研究可能是今后的研究热点。

Comparison of the coding regions of BH1-BH4 genes showed that BH1 had a lower sequence identity to other previously published B-hordeins than the other three B-hordeins obtained in this study. BH1 was then cloned in a bacterial expression vector based on bacteriophage T7 RNA polymerase. The resulting plasmid produced a 28.15 kDa protein in Escherichia coli. The potential value of B-hordein genes in grain quality improvement of hull-less barley has been discussed.
