同时，此系统的quorum被划分成为由若干高可靠性节点组成的高性能子quorum和由全部节点组成的选择quorum两类quorum，采用自适应容错协议来满足高可用性和高性能的要求。

Be living in the deep well ultradeep well prospecting process ,Since radial direction force 、Eddy is stird 、Elements such as horizontal vibration and so on being ,In the wake of well drilling time the increase ,The auger post writings is used the casing inside wall crossrange strenuously to broaden ,It is more and more grave to cause casing and drilling rig to join the wornout problem .

论文摘要：在深井超深井勘探过程中，由于径向力、涡动、横向振动等因素的存在，随着钻井时间的增长，钻柱作用于套管内壁的侧向力增大，导致套管和钻具接头磨损的问题越来越严重。造成钻具耐磨带失效的主要原因有地层研磨性、钻杆的井下工况、耐磨材料选择与

Luxurious aesthetics: Kwong Kai-storey steel elegant floor coverings, like there is a wide variety of solid wood, flower type and color for customer selection, the hollow design of cellular and have sound-absorbing, sound, decompression performance, making the floor of the load-bearing capacity substantial increase in the floor also reduces the weight of the characteristics of light can greatly reduce the load-bearing floors.

Breeding of transgenic rice restorer line for multiple resistance against bacterial blight, striped stem borer and herbicide(1) Transgenic rice line Zhongguo91 (carrying cry1Ab and bar gene) and elite restorer line Hui773 were crossed, then backcross was carried out three times using Hui773 as recurrent parent and self-cross was carried out one time.

多抗性(抗白叶枯、螟虫、除草剂)转基因水稻恢复系的培育(1)将恢773与携有转cry1Ab和bar基因的水稻新品系中国91(cry1Ab)杂交，并以恢773作为轮回亲本，连续回交三代和自交一代，对各回交世代的单株进行cry1Ab和bar基因的PCR分析、田间抗虫性鉴定和除草剂Basta抗性鉴定，经过选择获得了转基因水稻恢复系T773-1，田间种植对螟虫及除草剂Basta表现很好的抗性。

Under high temperature stress, the former is higher than the later in the speed of leaf starch grain degradation, metabolism and transformation into carbohydrate which can be transported outside, while lower in storage starch consumption in the leaf sheath, this mechanism is important to rice to spend temporarily high temperature hurt. The cell membrane thermal stability expressed by the thermal death time at 50℃ could be used as an accurate and handy physiological index to rice breeding for heat tolerance fitting individual plant selection and identification at grain-filling stage in future.

在高温胁迫处理下，叶片中淀粉粒降解代谢转化为可外运碳水化合物形式的速度是耐热品种大于不耐热品种，而消耗叶鞘中贮藏淀粉的速度则小于不耐热品种，这种机制对于水稻度过暂时性的高温热害具有重要意义。50℃热致死时间所表示的细胞膜热稳定性可作为今后水稻灌浆期耐热性育种中适合单株选择鉴定的简便、准确的生理指标。
