采用准稳态的极化试验研究了各主要试验参数对碳钢在3%NaCl溶液中点蚀电位的影响，结果表明：3种碳钢钝化的临界pH值约为8 0 ；当T =2 0℃～35℃时，点蚀电位值Eb10 0 随温度的降低而变正；当电位变化速度慢于30mV/ 30s时，Eb10 0 随电位变化速度的减小而变负；试验面的粗糙度越大，点蚀电位越

The nanoplex were smaller than the unmodified nHAP; thelipiodol/nanoplex emulsion, with the mean diameter at 75±11.8nm can disperse moreuniformly and be more soluble and stable, contrary to the unmodified nHAP and nanoplex Conclusion: Nanoplex/pDNA mass ratios greater than 15 had exhibited completepDNA absorption onto positive charged polyplex and pDNA protection from thedestruction of nucleinase in rabbit serum. Unmodified nHAP may can\'t induce effectivegene delivery.PartⅡThe construction of the recombint eukaryotic expressive vector ofwild-type human p53 and RbObjective: To construct the recombint eukaryotic expressive vector of wild-type humanp53 and Rb by utilizing the theory of molecular medicine.

结果nHAP颗粒本身大小小于100nm，但由于颗粒表面本身带负电，不能包括有效地结合及保护DNA；经Ca~(2+)修饰后，颗粒可带正电，可一定程度地结合和保护DNA，但聚合物本身的中性电与带负电的细胞膜结合，而且本身的颗粒则变地容易聚集而成为很大的颗粒，也不利于细胞的吞噬；经PLL修饰后，颗粒溶解性提高，直径变小，表面带正电，电泳结果显示PLL-nHAP颗粒可包括有效地结合和保护DNA免受兔血清的破坏，而且复合物表面的正电也包括有利于与细胞膜的结合与吞噬。

Results Extensive and diffuse synovial hyperplasia can be seen in patients with RA;synovial pannus formation can be seen in 25 cases.

结果RA组病人均可见广泛、弥漫的滑膜增生，其中25例病人可见滑膜血管翳形成，而OA组仅7例病人可见轻度滑膜增厚，未见滑膜血管翳形成者(X2=55.78P.005)；RA组关节软骨及软骨下骨改变较严重且弥漫，而OA组软骨退变则较局限，且以关节摩擦大的部位受损为著，其软骨下骨改变较为局限，常常见于IV软骨退变；关节腔积液、半月板及韧带改变，在OA组与RA组之间无差异。

The group B presented lots of petechiae since the fifth week; the surface of right lung began less petechiae; during 26th week, the symptom of reduced volume and hard surface was less than before.

大体标本观察发现，单纯照射组大鼠于照射第5周时见肺脏肿胀、表面鲜红，并有暗红色斑片状出血；第12周时肺肿胀减退，表面瘀斑颜色转暗；第26周时其肺脏体积缩小、质地变硬，可见苍白实变灶。

AO mode haves the obvious seasonal variability. From winter to summer, the height of AO modes conversion becomes low, and the pleion in the boreal Pacific moves from the ocean to the East Asian land.

AO模态有明显的季节变化特征，从冬季到夏季，AO模态的转变层高度由高变低，北太平洋地区的正距平中心从海洋移到东亚大陆，从夏季到冬季，AO模态的转变层高度由低变高，东亚大陆上的正距平中心又移回到海洋上空。

However, production of pyruvaldehyde in galactose/glycine system was much less than that in glucose/glycine system at 60°C.

糖类的初浓度对褐变速率之影响，在1.2%~4.8%之间呈线性正相关；其中羊乳糖／甘胺酸系统的褐变速率大於葡萄糖／甘胺酸系统。

All sequences were aligned with S genes in GeneBank by BLAST software.The result indicated that all 10 fragments contained domain encoding 5 high conservation regions(C1,C2,C3,RC4,C5) and hypervariable regionof rosaceous S-RNase.RHV and intron characterized S gene furthermore.

测序结果表明，这些DNA片段的核苷酸序列中都具有编码蔷薇科S-RNAase 5个高度保守区域：C1、C2、C3、RC4、C5的序列、编码高变区的序列以及变异度很大的内含子序列，并且其高变区和内含子序列具有扁桃S基因特异性。

Veined,stockwork and alteration-sheathed gold ores have been found in the area,belonging to four genetic types:the volcanic hydrothermal ores related to early—middle Carboniferous volcanism; subvolcanic hydrothermal ores related to intermediate—acidic porphyry intrusions; hydrothermal ores to the granitic intrusion and dynamo- hydrothermal ores related to regional dynamic metamorphism along the faults.

矿石类型有含金石英大脉型、石英网脉型和蚀变岩型。矿床成因类型有4种：一为火山热液型，其成因与区内早—中石炭世火山作用有关；二为潜火山热液型，与中酸性斑岩体侵位有关；三为岩浆热液型，与花岗质岩浆的侵位有关；四为动力变质热液型，沿断裂带分布于蚀变玄武岩中，系区域动力变质作用的产物。

In this paper,the problem of adaptive stabilization of slowly time－varying systems with unmodeled dynamics is investigated in the presence of unknown but bounded disturbances.

研究了含有未建模动态的慢时变系统的自适应镇定问题。考虑的对象具有非最小相位、含未建模动态和大范围时变参数等不良特性，且存在未知但有界外部扰动。

In the present condition, the measures to decrease investigation cost in maximum degree and to acquire the best investigation benefits are below: Reforming the investigation system, changing the "Regarding piece as the dominant factor" to "Regarding piece as the dominant factor","Piece and strip combination". Strengthening educational training, legal propagate and legislation. Improving the professional qualities of investigators and the legal quality of citizen. Uprighting the relation of "Investigation" and "Control", and changing the passive investigation to initiate investigation. Increasing criminal risk and cost to decrease and prevent the occurrence of crime . Displaying the guiding role of media in propagation. Respecting the objective law of new-born things development. Enlarging the input of science and technology and realizing sections link on network, resources enjoy together and examine and approve on network. Ensuring the stability of funds and scientific management.

在目前条件下，要最大限度地降低侦查成本，获取最佳侦查效益的措施是：改变侦查体制，变&以条为主&为&以块为主&，&条块结合&；加强教育培训和法制宣传、立法工作，大力提高侦查人员业务素质和国民素质；摆正&侦&与&控&的关系，变被动侦查为主动侦控；加大犯罪的风险和成本，减少和预防犯罪的发生；正确发挥新闻媒体宣传的导向作用，尊重新生事物发展的客观规律；加大科技投入，实现区域联网，资源共享，网上审批；经费的稳定保障及科学管理。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
