One has proved that the viewpoint that the horizontal sidetrack is the most important technology for exploiting "large scale"unswept remaining oil in mature oilfields from three aspects.They are:(1) the horizontal sidetrack is the main technology for exploiting primary rich areas of"large scale"unswept remaining oil in mature oilfields;(2) the horizontal sidetrack can hit any rich area of"large scale"unswept remaining oil in reservoirs;(3) the cost of the horizontal sidetrack is more low in contrast with the vertical well and the conventional horizontal well.

从三方面论证了侧钻水平井是开采成熟油田&大尺度&未波及剩余油最重要的技术这一观点：①侧钻水平井是开采成熟油田&大尺度&未波及剩余油主要富集区的主要技术；②侧钻水平井可钻达油层中任何部位的&大尺度&未波及剩余油富集区；③侧钻水平井比钻垂直井和常规水平井费用低得多、更加经济。

The influence of untransformed austenite areas on the properties of austenitic-bainitic ductile iron is discussed.

该文用彩色金相技术显示了奥氏体—贝氏体球墨铸铁中未转变奥氏体区的组织，用定量金相研究了等温淬火温度和时间对未转变奥氏体区的影响，讨论了未转变奥氏体区对奥—贝球铁性能的影响。

The grafting effect and mechanism was charac- terized by FTIR,The heat stability of unvulcanized and dynamical mechanical proper- ty of vulc- lcanizates of SBR and SBR-g- were tested by TG and DMA respectively. medium-resistance properties of SBR and SBR-g- vulcan- izates were also investigated.The results showed that addition of St accelerated GMA grafting onto SBR and control the decomposition of SBR. When the conditions were GMA/St/DCP was 8/4/0.3 and grafting temperature was 160℃.

结果表明，St对提高接枝率、抑制SBR的降解起到了积极的作用；SBR中聚丁二烯的α－H和双键共同参与了GMA/St熔融接枝反应；当SBR/GMA/St/DCP=100/8/4/0.3、接枝温度为160℃时，SBR的接枝率较高（23.78%），SBR–g–硫化胶的拉伸强度和撕裂强度比SBR硫化胶的分别提高了119%和27.4%；SBR–（GMA--co-St）未硫化胶的Tg比SBR未硫化胶的高，而耐热分解性能优于SBR未硫化胶；SBR–g–硫化胶在低温条件下的刚性增大、弹性降低、具有较低的内耗，在常温下的阻尼性能较高，但弹性性能保持较好；SBR–g–硫化胶的耐热稳定性以及耐非极性有机溶剂的性能优于SBR硫化胶。

This time, the weighted F-value is 4.898, unweighted F-value is 2.957, that shows the weighted gap between class are more obvious that unweighted one, that is, the accuracy of the clustering algorithm is significantly higher than unweighted fuzzy clustering algorithm.

此时，加权的F值为4.898，未加权的F值为2.957，说明加权的类间的差距比未加权的明显，即该算法聚类准确率要明显高于未加权的模糊聚类算法。

Results there 9 species of rodents belonged to 4genus,2 family,2order were found and rattus norvegicus was predominated, followed by rattus flavipectus. four species of fleas belonged to 4 genus of 3 families were identified and the predominated species was xenopsylla cheopis. natural dead rat were not discovered; yersinia pestis and f1 antibody were not detected.

结果 在调查市县发现啮齿动物隶属2目2科4属9种，以褐家鼠为优势鼠种，黄胸鼠次之；食虫目动物1科1属1种；梳检鼠体检获鼠体蚤3科4属4种，以印鼠蚤为绝对优势蚤种；未发现自毙鼠；未分离出鼠疫杆菌及未检测出f1抗体阳性血清。
