分叉

The nonlinear response and bifurcation of piecewise dynamic system are investigated.

研究了存在分段线性情况下动力学系统响应的分叉。

Results: Successful reopening of the vessels was obtained in both patients without the evidence of postsurgical ischemic event.

结果表明，在动脉切开术期间，如果手术前的血管造影提示是颈动脉分叉远侧的血管阻塞显明，并能通过ICA获得黑质返流的血流，那么直接颈动脉内膜切除术可以安全地执行。

Inflorescence development was divided into four stages, the initiating expansion pseudobulb, initiating inflorescence (1-3 cm in flower stalk length), the initial-branching flower stalk, and full bloom inflorescence, respectively. The activity variations of mannan cleaving enzymes,-mannosidase (EC 3.2.1.25), endo--mannanase (EC 3.2.1.78), and the mannan synthesizing enzyme, GDP-mannose pyrophosphorylase (EC 2.7.7.13), were analyzed during different stages to better understand the role of mannan-metabolizing enzymes during inflorescence development of the Oncidium.

将花梗发育过程分为四个阶段，分别为假球茎刚膨大、刚抽梗（花梗长度约1-3公分）、花梗刚分叉以及花盛开，分析参与分解甘露聚醣之酵素－β-mannosidase（EC 3.2.1.25）及endo-β-mannanase（EC 3.2.1.78），与合成甘露聚醣之酵素－GDP-mannose pyrophosphorylase（EC 2.7.7.13），在不同阶段假球茎内的活性变化，了解在花梗发育过程中代谢甘露聚醣之相关酵素所扮演的角色。

MTA was used to manage clinical problems. These included pulpless permanent teeth with incomplete root formation and perforation in roots or furcations.

本研究收集了2000—2001年期间在临床上治疗的牙根或根分叉穿孔的病例和根尖未发育完成并牙髓坏死的病例，用MTA修补穿孔和行根尖屏障术，共治疗10例，12颗患牙。

The follow-up periods were various from 6m to 21m. The apical MTA barrier technique was used to manage pulpless permanent teeth with incomplete root formation. The postoperative radiographs showed complete repair of periradicular tissue in 5 of 7 teeth and improvement obviously in other 2 teeth. Only one case (1 tooth) had a 3mm periodontal pocket in four perforation repair cases. The lesion at the perforation sites was improved obviously.

追踪观察时间为6-21月。4例穿孔修补的病例，均为延迟修补，除一例为根尖1／3处的病理性吸收外，其余患牙的穿孔部位位于牙根的冠1／3或根分叉处，一例6m复查时有3mm的牙周袋形成，其余患牙骨吸收暗影均明显缩小。7例根尖发育不全并无髓牙的病例均为成人，5例根尖暗影完全消失，2例明显缩小。
