The Board of Directors of AUO and TPV Technology approved, on the basis of strategic alliance, to set up a joint venture company combining TPV\'s well-branded image and business infrastructure in the European market, and the strength of AUO\'s leading technology in TV panel manufacturing.

友达光电与冠捷科技公司双方董事会通过，在策略联盟的基础上，将借重冠捷科技过去在欧洲市场奠定的良好品牌形象及基础，辅以友达长期在电视面板制程技术领先的优势，成立合资公司。

The simulations of two models are close to canopy albedo observation in this band. This indicates that the two-stream model can simulate the canopy albedo very well and the improvement of four-stream model is limited. The results also show that the albedo of the canopy modeled by the four-stream model is greatly improved than that of the two-stream model in the NIR band.

这表明在可见光波段，二流模式已经能够较好模拟冠层反照率，四流模式能够提高的精度范围有限；在近红外波段，因叶片散射率值较大，两个模式模拟结果差别较明显，四流模式模拟的冠层反照率相对二流模式的模拟结果更接近观测值。

Considering many biophysics processes such as the atmosphere,hydrology,plant leaf N content et al.a multiple layer,two-leaf canopy model for predicting of mass transportation and energy exchange between plant canopies and the atmosphere has developed after dividing the canopy height into three layers,and the sunlit and shaded leaf area index was computed respectively at different layers through introducing a foliage clumping index,it is important to distinguish the spatial light distribution and so leaf photsynthesis.

多层—双叶模型对冠层上方碳通量的模拟：综合考虑农田水、热因子及叶片氮含量的非线性垂直分布对碳、水循环的影响，将农田按植株高度分为上、中、下三层，并通过叶片集聚指数计算阴、阳叶面积以区分叶片的空间分布受光状态，建立了均匀农田与大气间物质输送和能量交换的多层—双叶模型，对农田冠层上方基于光合—呼吸的碳循环过程进行了模拟应用研究。

67 of old person latent to split tooth carry on clinical diagnosis, adopt the complex treatment method according to different situations to 63. 4 shallow form latent to split tooth, dental pulp normal having subjective symptoms to be only competent to transfer tooth treat jointly; Have deeper crackle as to 5, the vigor of dental pulp is normal, but there is trouble tooth of dentine irritated symptom, prepares against the hole, is filled with on the crack while adjusting the tooth contract; Pulpitis, 22 58 drops of trouble tooth with the sharp disease, symptom of the root already appear to 36, go ahead of the rest steel wire ring pitch or make, bring ring bonding in order to protect corona, rub except that high sharp abrupt slope, after dispelling the tooth and shutting the wound, the root canal with complete regeneration, observe for 2 weeks, after there is no clinical symptom, preceded and repair completely in time.

对63例老年人67颗隐裂牙进行临床诊断，并根据不同情况采用了综合治疗的方法。4颗浅表的隐裂牙，牙髓正常且无自觉症状仅行调牙合治疗；对于5颗有较深裂纹，牙髓活力正常，但有牙本质过敏症状的患牙，调牙合同时在裂隙处备洞、充填；对36颗已出现牙髓炎、22颗伴有根尖病症状的58颗患牙，先行钢丝环扎或做带环粘结以保护牙冠，磨除高尖陡坡，消除牙合创伤后，再行完善的根管治疗，观察2周，无临床症状后，及时做全冠修复。

Results:The 3-dimensional finite element models of the minimum distal occlusal structure defect with restoration were created, which included metal crown with exterior anatomic morphology of the mandibular first molar, tooth preparation, filling material and the structure of periodontal membrane.

本研究采用逆向工程技术，通过先进的三维激光扫描技术，三维造型设计技术建立几何模型，将几何数据导入有限元分析软件中，建立了右下颌第一磨牙具有根管和远中面(distal occlusal，DO)最小缺损的全冠修复牙体预备体、充填体、金属冠、牙周膜的三维有限元模型。

Therapeutic effectiveness was observed on the restoration of the severe crown defect of the front teeth when treated with baked porcelain crown after one visit filling of the tooth root.

对前牙牙冠严重缺损者采用一次性药物根管充填，制作桩核，即时备牙，取模、制作金属烤瓷冠，从而明显减少了患者就诊天数及时间。

The P wave duration and P 2R interval were increased while pacing at right atrial appendage 1 The activation time from pacing site to His bundle and coronary sinus was the longest in pacing at right atrial appendage , while the activation time in pacing at Koch triangle , Koch triangle with high right atrium and biatria was significantly shorter especially pacing at Koch triangle and Koch triangle with high right atrium1 There were no significant differences in right atrium pressure among all pacings1 Conclusion It is suggested that Koch triangle pacing could probably replace high right atrial with coronary sinus pacing and biatrial pacing 1

从心房激动顺序分析，右心耳起搏时，激动传至希氏束区及冠状窦区的时间最长，而 Koch三角、Koch三角+高位右房及双房起搏时则较短，尤其是 Koch三角、Koch三角+高位右房起搏缩短更明显。另外，不同部位、不同方式起搏时右心房压力无差异。结论 Koch三角起搏在某种程度上可替代高位右房+冠状窦起搏及双房起搏。
