The microstructures and second phases were examined by transmission electron microscopy.It is found that the specimen treated by 500 ℃/100 h has the best corrosion resistance among all the specimens.TEM analysis of the specimens tempered at 500 ℃ with different time shows that the second phase changes from the seriate strips to the banding...

用透射电镜研究了这些样品的显微组织和第二相，观测到随着保温时间延长，500℃下保温样品中的第二相由连续片层逐渐转变成带状分布的颗粒，保温时间达到100 h时，基体内析出βNb.560℃下保温样品与500℃下保温样品有相似的组织转变过程，只是时间大幅缩短，保温仅10 h时，基体已完全再结晶为等轴晶。

Inflammatory cell infiltration and subserous hemorrhage appeared in 12 and 24 h group.

结果：伤后各组胃黏膜COX2的表达明显高于对照组；实验组各组血浆内毒素水平均明显高于对照组（P.05），于伤后8 h达高峰；伤后各组胃组织出现逐渐加重的胃黏膜下充血、水肿，12、24 h组出现炎细胞浸润、浆膜下出血。

We concluded that DGR was probably an independent etiological factor and might play a synergistical role in the pathogenesis of gastric mucosal lesions along with gastric acid and H.

DGR与H。 pylori感染和胃内酸度均无关，DGR可能是一个独立的致病因素，与H。

Results indicated that the water contents in wheat leaves of uncontinuous drought treatments did not largely changed, but that of roots obviously decreased; the relative water contents in wheat leaves and roots of 24 h continuous treatments were both decreased obviously.

结果表明，每天间断干旱1~4 h处理的小麦叶片相对含水量变化较小，而根系相对含水量变化较大；连续干旱24 h后叶片和根的相对含水量均显著下降。

The minimum accumulation occurred at 96 h, at which transcripts were only 0.07 fold of that in uredinisopore. During incompatible interaction between Pst and wheat, PsCdc2 was down-regulated and its accumulation was lower than that in urediniospore.

在非亲和组合中，该基因表达基本呈下调趋势，在接种后各个时间点的表达量均低于在夏孢子中的表达量，其中接种后12 h时表达量最高，但仅为夏孢子中表达量的0.34倍；接种后96 h表达量最低，为夏孢子中表达量的0.02倍。

Secondly, the genomic DNA is extracted from Zostera marina L. and then amplified by PCR with two oligonucleotide primers synthesized to obtain the partial nucleotide sequences of the Na~+/H~+ antiporter gene. The Na~+/H~+ antiporter gene clone was obtained after a series of manipulation: purificatioin of PCR product, ligation and transformation of recombinant plasmids, blue-white selection and so on. DNA sequence analysis shows that its DNA sequence is highly homologous with the genomic DNA sequence of E.

其次，通过提取大叶藻基因组DNA，根据设计的简并性引物进行PCR扩增，纯化PCR产物，连接，重组质粒转化，蓝白斑筛选等操作，并测序，提交测定序列到NCBI进行BLASTN，结果表明：该序列与大肠杆菌的基因组序列相似性较高，而与其它物种的Na~+/H~+逆向转运蛋白基因没有相似性。

Mechanical ventilor assist time was 4～14(average 8±2.9)h; 24h chest drainage was 110～360 (average 252±62.9)ml. All patients didn't appear thromboembolism and gas embolism and rehabilitation discharge successfully.

手术后呼吸机辅助时间4～14(8±2.9)h；24 h胸腔引流量110～360(252±62.9)ml.15例患者没有出现血栓栓塞和气体栓塞并均顺利康复出院。

The highest agglutinating activities were observed at 24 h post-injection.

溶血活力在注射疫苗后有所增强，注射后6 h时1.08×106、1.08×107cell/ml组的活力达到最高，而1.08×108cell/ml组12 h时活力达到峰值。

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。
