简介：二细菌的老家(BB)抵抗基因，Xa21和Xa4，从IRBB24被介绍进杂交稻restorer线Mianhui725，它高度产生BB，由使用杂交和分子的帮助标记的选择技术。四根相应恢复系线通过与分子的标记测试R目标基因并且分析父母遗传背景被获得。有特定的紧张ofXanthomonasoryzaepv的四根线和他们的混血儿的接种。oryzae，P1，P6和七个代表汉语拉紧病理型，CⅠ-CⅦ，证明所有四根线和他们的混血儿是到BB的高度抵抗、介绍的宽广抵抗光谱。G46A/R207-2的混血儿显示了好农学的人物和高产潜力，并且R207-2被称为Shuhui207。

简介：极其细小磨擦非结晶的合金催化剂被化学减小与KBH4准备。在在气压的cinnamaldehyde的液体阶段加氢期间，Ru-B催化剂准备了展出优秀选择到cinnamyl酒精。当加氢与超声的照耀被执行时，当到cinnamyl酒精的选择仍然保持几乎未改变时，反应率能极大地被提高。加氢率随超声的频率或照耀时间的增加被增加。根据各种各样的描述，例如XRD，XPS，TEM，赌注和ICP，结构、电子的特征上的超声的照耀的效果磨擦催化剂简短被学习。同时，催化表演上的ultrasonication的提升效果也基于cinnamaldehyde的选择加氢被讨论到cinnamyl酒精。

简介：客观：为胫骨的intramedullarynails.Methods的远侧的锁住评估帮助thecomputer的汽车框架航行系统的临床的可行性和效果：系统的硬件部件与一个监视器包括了一台PC计算机，汽车机械立体声战术的定位立方的框架，脚持有者和起作用的本地化仪器。特殊航行软件能被用于X光检查fluoroscopic图象和工具的real-timecontrolling航行的登记。近胫骨、腓骨的破裂的21个案例被对待，关上的intramedullary钉其6在中间第三包含了，12在里面中间、更低第三，3在里面降低第三。涉及锁住的过程的C手臂排列和登记时间，fluoroscopic时间和钻的时间被记录。unreamed或铰大的胫骨的钉子的尺寸从8/300-11/330。结果：除了1的所有远侧的洞成功地被锁。在41个锁的洞(21.95%)中的9个里，练习小点摸了没有钉子和临床的后果的损坏，锁洞的运河。荧光检查时间每一些螺丝钉是2.23s±0.31s。结论:为远侧的锁住的帮助计算机的汽车框架航行系统很好被设计，对容易操作并且不在过程期间需要另外的仪器。发达系统使医生能精确用就一些校准计算机的X光线照相术的图象在整个解剖遨游外科的仪器。X光暴露的全部的时间能显著地每过程被减少。
