Methods: The model was established with two cuff technique; The donor was perfused through the abdominal aorta with cold perfusate; The anastomosis of the suprahepatic vena cava was sutured end to end with 8~0 nylon line, and the continuity of portal vein and infrahepatic vena cava were established by means of cuff method respectively. The bile duct anastomosis was performed with internal stent.

采用二袖套法行大鼠原位肝移植，供体经腹主动脉进行肝脏冷灌注，肝上下腔静脉采用手缝合法进行吻合；门静脉和肝下下腔静脉用袖套法吻合；胆总管采用单管内支架胆管端端吻合。

Using Eriochome cyanine R staining, we found that Al accumulation on surface of root tips was positive related to the inhibition of root growth in treatments of 0 - 80μmol·L~(-1) Al for 24 h. Exchangeable Al in apoplast and symplasm of root tips of wheat was effectively desorbed by 5 mmol·L~(-1) CaCl_2 at 4℃.

铬化青R染色可以原位显示0-80μmol·L~(-1)Al处理后根尖表面Al的吸附量与根尖伸长受抑制程度具有很好的一致性。5mmol·L~(-1) CaCl_2溶液可以有效洗脱10和40μmol·L~(-1)Al处理24小时后小麦根尖质外体和共质体中可交换态Al。

A combination analysis of SIP and in situ microbiological methods was applied on the anaerobic digestion of biomass organics suffering from severe acids inhibition. The studies found that accumulated acids were degraded mainly by Methanosarcina firstly with acetoclastic pathway and then with hydrogenotrophic pathway under mesophilic condition, whereas acids were mainly degraded to methane by the tandem reactions of syntrophic acetate oxidation and hydrogenotrophic methanogenesis under thermophilic condition.

联合应用稳定同位素表征技术和微生态原位表征方法，对高浓度有机酸胁迫条件下的生物质类有机物厌氧发酵甲烷化途径的研究结果表明，面临高浓度有机酸迅速累积的环境，中温发酵条件下，优势菌种为甲烷八叠球菌，依时间次序，通过乙酸发酵和氢营养型途径利用累积的有机酸产生甲烷；而在高温条件下，有机酸则通过乙酸氧化和氢营养型甲烷化途径的串联反应被降解。

In the study, a set of near isogenic lines of CMS-S, S-Mo17Rf3Rf3 and S-Mo17rf3rf3, were adopted, and TdT-mediated dUTP nick-end labeling, in situ immunolocalization of cytochrome c and DNA ladder assay were employed to study the programmed cell death process on cytology and DNA level. The microscope observation evidenced that tapetal cells of fertile anthers kept intact until microspores, and then were disintegrated on later developmental stage.

Conclusion］The pristine cases could receive significant curative effects through open reduction and internal fixation, the late cases could also receive significant curative effects through instep re-establishment and tarsometatarsal joints Fusion.

结论］早期陈旧性跖跗关节骨折脱位可行切开复位内固定术，疗效满意，而晚期的陈旧性跖跗关节骨折脱位，行足弓重建跖跗关节原位融合术，也可取得较好的治疗效果。

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.
