结果表明，加入适当比率的二次空气，不仅能够在相当宽的流速范围内使火焰很好地稳定在中间段，而且能得到低水平的CO排放浓度，特别对较低当量比效果更为明显。

With the co-precipitation, using cross experiment, constitute of catalyst (include 2 equations), proportionment of precipitator, aged time, calcine temperature, had been discussed-how to influence the activity of catalyst. The activity will be primed if prepareing the catalyst with CuO:ZnO:CeO_2=6:9:10, using NaOH as precipitator, aged time 3h, calcining the calatyst at 450℃.

在共沉淀法中利用正交试验对催化剂中各种物质的配比量、沉淀剂类型、陈化时间和焙烧温度这4种因素进行了4水平分析，结果显示制备催化剂时使用的金属盐Cu(NO_3)_2、Zn(NO_3)_2和Ce(NO_3)_3的物质的量之比符合n_1∶n_2∶n_3=6∶9∶10、并且NaOH溶液作沉淀剂、3h陈化后在450℃焙烧，制得的催化剂催化效果最好，在130℃时CO转化率即达到99％以上。

LaCr_(1-x)M_xO_3(M=Co, Fe, Ni, Sn, Ti)and LaNi_(1-x)Ti_xO_3 compounds were synthesized by sol-gel technique in this paper. The thick film based sensors were fabricated and their gas-sensing properties were tested in the acetone, ethanol, normal propyl alcohol, carbinol, formaldehyde gases etc.

本文采用柠檬酸盐溶胶-凝胶法合成了LaCr_(1-x)M_xO_3(M=Co，Fe，Ni，Sn，Ti)和LaNi_(1-x)Ti_xO_3系列化合物的纳米粉体，并制备了厚膜型气敏元件，在丙酮、乙醇、正丙醇、甲醇、甲醛等有机气体中测试了它们的气敏性能。

Following are summary of our works:(1)The powders of LaCr_(0.9)Co_(0.1)O_3, LaCr_(0.9)Fe_(0.1)O_3, LaCr_(0.9)Ni_(0.1)O_3, LaCr_(0.95)Sn_(0.05)O_3 and LaCr_(1-x)Ti_xO_3(x=0.0-0.3) were single perovskite phase with orthorhombic structure. The gas-sensing properties of their thick film sensors were tested in the acetone, ethanol, normal propyl alcohol, carbinol and formaldehyde organic gases. The sensitivity of the sensors can not be enhanced effectively by doping Co、Fe、Ni、Sn elements in B-site of LaCrO_3. Ti dopant with proper concentration can greatly improve the gas-sensing properties, which make the sensor display higher sensitivity and quicker response-recovery characteristics.

所得结果摘要如下：(1)LaCr_(0.9)Co_(0.1)O_3、LaCr_(0.9)Fe_(0.1)O_3、LaCr_(0.9)Ni_(0.1)O_3、LaCr_(0.95)Sn_(0.05)O_3和LaCr_(1-x)Ti_xO(来源：ABfd1dC论文网www.abclunwen.com)_3(x=0.0-0.3)粉体为正交单相钙钛矿结构，其厚膜型气敏元件在350℃时对丙酮、乙醇、正丙醇、甲醇、甲醛等有机气体的气敏性能测试表明：0.1mol Co、Fe、Ni和0.05mol Sn元素在LaCrO_3的B位进行掺杂后，不能有效提高材料对以上测试气体的气敏性能；而Ti元素的适量掺杂可以极大地改善LaCrO_3的气敏性能，使之显示出对丙酮气体的高灵敏度和快速响应恢复能力。

This study examined the effect of the HO inhibitor zinc protoporphyrin Ⅸ on the expression of neuronal NOS mRNA and protein and also the plasma NO content in rats with recurrent FS. The goal was to study the effect of CO on the NOS/NO system.

本研究观察HO抑制剂锌原卟啉Ⅸ对FS大鼠海马神经元型NOSmRNA和蛋白表达及NO含量的影响，以探讨CO对NOS/NO体系的调节作用。

Methods A total of 60 rats were employed and equally divided into 5 groups, i.e. control, HPH, hemin, Tin Protoporphyrin and low concentration CO groups.

60只Wistar大鼠随机分为5组：正常对照组；低氧肺动脉高压组；血晶素组；锡原卟啉组；低浓度CO组；每组12只。

吡啶与Co结合的速率比Fe结合的速率快。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
