An antibody phage library was screened with two target molecules, IFNα-2a and FGFR-GST, and the KD value of each round of panning was measured. It was found that the apparent KD values decreased along with each additional panning round, which indicates the increase of the binding affinity between the phage and the target molecules. This result shows that the KD value is a reliable intrinsic parameter and a new method for screening efficiency detection is thus provided.

处理上隅角瓦斯的J型通风系统

矿业安全与环保 2005年第3期32卷 62-63页

作者：王慧堂中国矿业大学

由于工作面单产提高,工作面瓦斯涌出量增大,原有的U型通风系统不能有效解决工作面瓦斯超限问题。为此,王庄矿开发试用了J型通风系统,在工作面瓦斯涌出量达15～25m3/min的条件下,供风量为1300～1600m3/min,消除了工作面上隅角瓦斯超限。

The global spin alignment of vector mesons has been observed by the STAR collaboration at the Relativistic Heavy Ion Collider （RHIC） at Brookhaven National Laboratory （BNL）.It provides a unique opportunity to probe the correlation between the polarized quark and antiquark in the strongly coupled quark-gluon plasma （sQGP） produced in relativistic heavy ion collisions,opening a new window to explore the properties of s *** addition,spin alignments of vector mesons have also been observed in other high-energy particle collisions such as e+e-annihilations at high energies where hadron production is dominated by quark fragmentation *** results obtained are quite different from those obtained in heavy ion collisions where quark coalescence/combination mechanism dominates suggesting strong dependence on hadronization *** comprehensive studies in different hadronization processes are *** this article,we present a brief review of theoretical and experimental advances in the study of vector meson’s spin alignments in a variety of high-energy particle collisions,with emphasis on hadronization mechanisms.
