半硬粒高赖氨酸玉米突变——开采号

半硬粒高赖氨酸突变体开采号是从北京农家种二黄玉米自交选系过程中分离出的新资源.它是1984年在二黄自交4代的单株果穗上出现的,经过选择加代,第7代成为各种性状稳定的纯合自交系.1991年经墨西哥玉米小麦改良中心分析测定,赖氨酸含量占百克蛋白质的4.2%,即占全子粒的0.411%.而普通玉米自330(对照)赖氨酸含量占百克蛋白的2.3%,开采号比普通玉米(自330)赖氨酸含量高82%.它是继奥帕克-2(O2)、弗洛里-2(fl2)、奥帕克-7(O7)三个突变体之后发现的又一个高赖氨酸玉米新资源.以开采号转育的高赖氨酸玉米子粒,可克服O2转育的容重低

汉水泉三号矿井多煤层联合开采开拓方案

针对汉水泉三号矿井多煤层赋存特点,借鉴国内外现代化的矿井的经验,利用一个开采水平和一个辅助水平实现开拓两组煤层,从井筒形式、开拓方式、巷道布置等方面进行矿井开采设计,充分发挥了一个开采水平和一个辅助水平联合开拓全井田的优势,对类似条件矿井开拓方案具有一定的借鉴意义。

康家滩矿88101综采面通道贯通回采期间的顶板岩层控制分析

分析了康家滩矿8号煤层88101首采工作面末采贯通期间的矿压显现,以及回撤通道的支护控制问题,对以后康家滩煤矿的开采决策有重要的参考借鉴价值。

Design of DSP-based Embedded Video Remote Monitoring System

Presented is a scheme of an embedded video remote monitoring system based on TMS320DM642. Using DM642 as the data processing core, the remote monitoring system is composed of video acquisition module, video processing module and communication module, which gives an implementation of class/mini driver module in DSP/BIOS integrated developing environment and also a common task module in application layer is achieved. The system realizes the entire functions of the analog video signal acquisition, H.264 video coding and Internet transmission. It provides the general connection for the future development and has good flexibility and extendibility. The system uses a modular design and overall development of programming methods to improve the efficiency of system development.
