查询词典 B

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.

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.
