Behcet disease （BD） is a chronic multisystem disease ＇that presents with recurrent oral and genital ulceration and recurrent uveitis. Vascular and cardiac thromboses are rare but life threatening complications. We report a case of right internal jugular vein and brachiocephalic vein thrombus and successive cardiac thrombosis, which was finally diagnosed with BD.

作者： LIU Ming-zhu HUANG xian-rong Faculty of Foreign Language Studies Wuhan Bioengineering Institute Wuhan 430415 China

With the development of society and economy, English gradually becomes a worldwide language. However, due to various kinds of reasons and restrictions, many problems still exist in present English language teaching in public English classes. This paper focuses on the application and effect of some useful motivational strategies in English classroom, such as making use of affective factors, developing good classroom atmosphere, and becoming an efficient manager. The researcher hopes that this contribution can offer some valuable guidelines to English teachers. Therefore, the existing problems can be solved gradually.

由电磁场互易原理得到的待测天线(AUT)幅度接收方向图(ARP)和发射方向图(ATP)相等的结论,具有易于被忽视的重要前提。对极化电磁波接收所作的深入分析表明,一般情况下,上述结论不成立。由于在ARP和ATP测试并形成过程中,AUT面临着自身和检验天线的各异收、发极化失配状态,受到不同的空间极化滤波影响。通常,ARP和ATP有差别,即同一个AUT的收、发方向图非互易。论文的分析还得到,线极化和圆极化AUT方向图不失真的简洁、正确测试方法。

Chiral oxazoborolidine borane complex was prepared from (αs, 4s)-2-dichloromethyl-4, 5-dihydro-α-(4-nitrophenyl)-4-oxazolemethanol with Borane in THF. The borane modified by chiral oxazoborolidine enantioselectively reduced aromatic ketones to second-alcohol with about 95%yield and medium optical yields. In the end of article, results are discussed and reduction mechanism is shown which proves the resulting major isomers fit very well.
