Prior reports of an association between transfusion and pneumonia may reflect transfusions received after pneumonia rather than etiologically relevant transfusions received before the onset of pneumonia.

先前报道的输血和肺炎之间的相关性可能反映肺炎后的输血情况，而不是肺炎发病前的病因学与输血相关的情况。

The maximal EL quantum efficiency is 0.45% for copolymer of fluorene and thiophene; 1. 8% for copolymer of fluorene and EDT; 1. 4% for copolymer of fluorene and DBT.

芴与噻吩共聚物的最大电致发光外量子效率为0.45%，芴与EDT共聚物的最大EL外量子效率为1.8%，芴与DBT共聚物的最大EL外量子效率为1.4%，这也是目前所报道的同类聚合物中EL外量子效率最高的。

Pymetrazine is chosed as the lead compound, and 21 compounds were firstly designed and synthesized. These compounds were characterized by introducing phenyl derivatives with different functional groups to replace pyridine ring with the isosteric principle and the method of homogeneous synthesis and reasonable biologically designing in order to find new compounds with potential biological activity. These compounds were confirmed by IR, H NMR and MS spectra.

本文选取吡蚜酮为先导化合物，运用电子等排理念，综合类同合成、生物合理设计的方法，引入含有不同官能团的苯基衍生物替代吡蚜酮的结构中心吡啶环，设计合成了21个未见文献报道的化合物，寻找具有潜在生物活性的新三嗪酮类化合物，通过核磁共振氢谱、红外光谱、质谱等手段进行了结构表征，并验证正确。

The absorption bands observed for Pb-pheophytin a at 462nm and 673nm , while for Pb-pheophytin b at 480nm and 662nm . Compared with pheophytin a and pheophytin b, all these bands red shifted more or less. Among the reported metallochlorophylls, the degree of red shift of Pb-pheophytin in Soret band was the largest by 54nm and 44nm for Pb-pheophytin a and Pb-pheophytin b, respectively.

实验表明：对铅叶绿素a和b系列来说，它们在Soret带、Q带的特征吸收峰分别在462nm，673nm和480nm，662nm；与脱镁叶绿素a，b相比，铅叶绿素a，b在Soret带和Q带吸收峰均有不同程度的红移；与现已报道的金属叶绿素相比，铅叶绿素a，b在Soret带的红移程度最大，分别为54和44nm；铅叶绿素不具有荧光活性，并能猝灭脱镁叶绿素的荧光。

Glycyrihizic acid can cause the polarigraphic catalytic wave of oxygen. GA scavenging superoxide ion is demonstrated chemically by the catalytic wave at molecular lever.

本文报道的甘草酸及其皂甙类衍生物存在下的氧极谱催化波，从分子水平研究了GA清除超氧离子自由基〓的化学作用机制，证实清除〓的活性基团是GA分子中与C＝O基共轭的C＝C双键，并非-OH基，纠正了文献观点。

Our main research work has been focused on the synthesis, characterization of substituted salicylaldehyde Schiff bases and their complexes, which are not reported in articles now. There are twenty-one new compounds in total.

本论文研究了目前未见国内外文献报道的、水杨醛中苯环上含有取代基的水杨醛缩脱氢枞胺Schiff碱及其金属配合物的合成与表征，共计获得了21个新的化合物，从而为后期生物活性的测定及不对称催化提供研究基础和实验样品。

In this study, new benzo[l,2,3]thiadiazole derivatives were designed according to relationship of structure and efficacy. The 9 novel compounds were synsthesized with following reactions. The chlorine atom in 2-chloro-3,5-dinitro-benzoic acid as beginning raw material was substituted by 2-methylpropane-2-thiol, esterified then with bromoethane, reduced by iron powder and cyclized to obtain ethyl benzo[l,2,3]thiadiazole-7 after diazonation reation.

本论文根据苯并噻二唑诱导剂的构效关系设计了新的苯并噻二唑的结构，并合成了9个未见文献报道的化合物，合成步骤如下：采用2-氯-3，5-二硝基苯甲酸为起始原料，苯环上的氯原子被叔丁基硫醇置换，羧酸由溴乙烷酯化，硝基由铁粉还原，随后经重氮化关环生成苯并[1，2，3]噻二唑-7-羧酸乙酯。

These results suggest that the products of the novel gene,mNHX1,on the vacuolar membrane,functions as a Na~/H~ antiporter and may be one of the most important factors determining salt tolerance in mulberry trees .

根据已报道的At-NHX1同源基因的功能推断，mNHX1所编码的细胞液泡膜上Na+/H+逆向运转蛋白是桑树抗盐性能的一个极其重要的因素。
