在天然林样方中182个类群均有分布，而人工林中仅见89类群；土壤无脊椎动物个体数方面天然林中共采集土壤无脊椎动物原始个数90201头，而人工林中采集52222头。

The members of the same genus and family were grouped together. The polyogenetic relationships of 8 families were Pyrgomorphidae →Chrotogonidae→Pamphagidae→Oedipodidae→Acrididae→Arcypteridae→Gomphoceridae→Cantantopidae.Pygomorphidae had closer relationships with Chrotogonidae as well as being the most ancestral group. Arcypteridae and Gomphoceridae were the sister groups and had closer relationships with most evolutionary Catantopidae. Tridactylidae was divided firstly as a suborder,which differs from the recent taxonomy distinctly. Haglidae and Gryllidae were grouped into suborder Ensifera, Tetrigidae and 8 families of Acridoidea were grouped into suborder Caelifera, as same as recent taxonomy.

分子系统树表明：科内的属和属内的种均优先聚在一起；蝗总科8科的起源关系为：锥头蝗科→瘤锥蝗科→癞蝗科→斑翅蝗科→剑角蝗科→网翅蝗科和槌角蝗科→斑腿蝗科；锥头蝗科与瘤锥蝗科关系较近，是蝗总科内最原始的类群；槌角蝗科和网翅蝗科互为姐妹群，与最进化的斑腿蝗科关系较近；蚤蝼科为独立的一支，最先分出，似为一个亚目，与现用的分类系统有明显差别；哈螽科和蟋蟀科聚在一起为剑瓣亚目，蚱科和蝗总科的8科组成短瓣亚目，同现用的分类系统。

Methods: We collected 121 of clinical isolates of Enterobacter, including 87 isolates Enterobacter cloacae, 34 isolates Enterobacter aerogenes, all of the isolates were detected by cefoxitin three-dimension test, drug resistance phenotypes estimation, cloxacillin disc synergy test and cloxacillin-potentiated disc diffusion test respectively to find high-level AmpC β-lactamase isolates, drug resistance phenotypes estimation were also used to detected high induction producing AmpC β-lactamases isolates, meanwhile, we took three-dimension test as standard method, and compared to other methods, then calculated the coincidence rates, sensitivities and specificities of them.

采用头孢西丁三维实验、纸片耐药表型推断法、邻氯西林纸片协同法、双纸片邻氯西林增效试验分别检测高产AmpCβ-内酰胺酶株，获得高产AmpC酶在肠杆菌属细菌中的表达状况。采用纸片耐药表型推断法检测诱导和高产AmpC酶，同时以头孢西丁三维实验为标准，其他三种方法与之相比较，分析它们检测高产AmpC酶的符合率、灵敏度和特异性。

It was found that the mechanical properties of the joints decreased by the alclad and it will be increased dramatically by removing the alclad. The effect of alclad on the bottom surface is larger than on the top surface. The mechanical properties of 2024-T3 joints will fall down because alclad is entrapped into the welded joints by the rotating and stirring tools during the friction stir welding, similar with "inclusion" in fusion welding.

研究结果表明，包铝层的存在明显降低了2024-T3铝合金搅拌摩擦焊接头的力学性能；去掉包铝层后接头的性能显著提高；下表面包铝层对接头性能的影响大于上表面包铝层；当2024-T3铝合金表面带有包铝层进行搅拌摩擦焊接时，在搅拌头的旋转和搅拌作用下，包铝层被卷入焊缝中，形成类似于熔焊的&夹杂&，从而使得接头的力学性能下降。

Results Internal jaundice was found in 63 cases (acute hepatitis in 40 cases, chronic hepatitis in 4 cases ,cirrhosis with ascites in 7cases ,cirrhosis with hepatic cancer in 4 cases, acute bacterial cholangitis in 1 case and acute calculous cholecystitis in 7 cases). Surgery jaundice in 21 cases (common bile duct stone in 9 cases, cholangiocarcinoma in 3 cases, pancreatic head cancer in 4 cases, focal pancreatitis in 1 case, ampullar carcinoma in 2 cases and biliary duct distal obstruction in 2 cases).

结果：内科性黄疸63例（急性肝炎40例，慢性肝炎4例，肝硬化伴腹水7例，肝硬化伴肝癌4例，急性细菌性胆管炎1例，急性结石性胆囊炎7例），外科性黄疸21例（胆总管结石9例，胆管癌3例，胰头癌4例，胰头炎症1例，壶腹癌2例，胆总管末端梗阻性病变2例）。

Methods forty patients with head/neck 16 slice CT angiograph were divided into two groups at random,each group has 20 cases, the plain scan and the CTP was performed before CTA to all 40 cases. Group A use CTP to obtain the peak time of contrasted artery as CTA delay time, and scan from head side to foot side. Group B use contrast media automatic bolus tracking to obtain delay time,scan from foot side to head side.two groups CTA images were collated.

使用16排螺旋CT对40例患者行头颈部CTA检查，随机分为两组，各20例，所有患者在CTA之前行脑CT平扫及脑CT灌注扫描，A组以CTP所显示的动脉峰值时间作为CTA的延迟时间，扫描方向为自头侧向足侧。B组使用造影剂浓度实时监控跟踪触发技术确定延迟时间，扫描方向自足侧向头侧扫描，两组CTA图像相对照。
