PC点是计划胼下型大脑前动脉远段动脉瘤外科策略的重要标志；5。熟悉纵裂入路相关的解剖和周密的术前、术中策略有助于提高脑深部病变的治疗效果。

The pleunm anti-static insulated material housing prevents short circuit led by the contact of welding spot and the metal channel of word sign. At the same time, the circuit uses particular constant current design and lightning arrester. Silicon rubber leads between modules of anti-aging and anti-cracking guarantee the long-term work in bad environment of open area while the low resistance of lead reduces the affection to the emitting brightness of LED by voltage drop.

其外壳采用阻燃防静电绝缘材料，可防止 PCB焊点与金属字槽壳的接触而产生短路，同时电路采用独特恒流电路设计及雷电吸收装置，模组间连接线采用软硅橡胶导线，在恶劣的户外恶劣环境下长时间使用，导线不会老化脆裂，同时导线内阻比较小，降低压降对LED发光亮度的影响。

Based on the fictitious crack model and critical crack tip opening displacement CTODc, the precritical crack propagation length △ac of concrete was determined by means of three point bending beams. According to the calculation value of △ac, the effective fracture toughness KunIc of concrete was evaluated.

本文采用虚拟裂缝模型，将临界裂缝尖端张开位移CTODc作为控制参数，利用三点弯曲梁试件通过迭代求得了混凝土裂缝亚临界扩展量的临界值△ac，据此求得了混凝土起裂断裂韧度KiniIc、等效断裂韧度KunIc值。

The following values was measured: angle of cusp line between the second and third molar, impact state and depth, distance from Rickett's Xi to distal cusp of third mandibular molar along the occlusal plane, anterior border of ramus to the third mandibular molar, distance from projection of distal contact point of maxillary third molar to intersection of pterygoid vertical on occlusal plane.The change between pre-and post-treatment was calculated and analyzed with SPSS10.0 software package.α angle, Xi-LTM, R-LTM, R-LTM were tested with independent-sample t test, impact state and depth was tested with Chi-square test. Influence of age on the values was also evaluated.

测量治疗前后的第二、第三磨牙牙尖连线角度、阻生状态和深度，Rickett's Xi点到下颌第三磨牙远中尖距离、下颌支前缘到第三磨牙远中尖距离、翼上颌裂切线到上颌第三磨牙后缘的距离及上、下磨牙的前移量，计算治疗前后各变量的差值，采用SPSS10.0软件包进行统计学分析，α角、Xi-LTM、R-LTM、R-LTM用t检验，阻生状态和深度用χ^2检验，比较年龄因素对各指标的影响。

Seeds 1 or 2 per valve, cylindric or quadrangular, reticulate or pitted; hilum at adjoining end of 2 seeds.

每裂爿种子1或2，圆筒状或四棱的，网状或具洼点；种脐连在2种子的末端。
