Function looks at the current bytecode in an execution context , and switches control out to a function appropriate for implementing that bytecode 函数主要察看执行上下文中的当前字节码，并将控制向外切换到一个适合实现该字节码的函数。
After finding the rectangle area of the eye position , we calculate the center of the rectangle to get the coordinates , then the canthus can be found 先找出眼睛区域的外切矩形，再取该矩形的中心，得到瞳孔的位置，并在此基础上找到眼角的坐标。
It is clear that the inner tangential wall of the basal cell is tightly related with the outer tangential wall of 4 - 5transfer cells which have been considered a part of the extent of vascular bundle 基细胞内切向壁与4 ? 5个传递细胞外切向壁紧密相连。紫穗槐同时以聚盐和泌盐两种方式抗盐。
Proofreading activity and low replication fidelity in vitro , distributive manner in dna synthesis , poor ability to discriminate nucleotides at the level of binding and also the possibility of its expanded roles in long patch ber , ner , dna replication and recombination at its excess state Lp表现出很低的dna复制保真度：它没有3 ’一5 ’外切酶活性因而在a复制中缺乏校读活性：对底物dn p鉴别能力低卜在长单链模权上催化dna复制时散布式的合成方式。
( 6 ) in this paper . adopting fea software ansys to simulation and analysis the al ecap process . in order to spread out studying of ecap in the future . the results show : die comer angle , the radius of round angle , the friction coffience of workpiece and die , the properties of die ( elastic modulus , possion ratio ) et al , have some degree impact on the deformation of materials ( 6 )采用有限元( fea )分析软件ansys对al的挤压过程进行ecap仿真与分析，为后续研究工作做好铺垫，分析结果表明：外切角、圆角半径、试样与凹模之间的摩擦系数、凹模本身的特性(如弹性模量、泊松比等)等等，对材料的变形量都由不同程度的影响。
The nucleotide ( nt ) sequence of the insert in phz1754 is 2299bps in size . computer assisted analysis of the sequence revealed an open reading frame ( orf ) with a g + c content of 70 . 3 % that would encode a protein of 552 amino acids ( aa ) . the nt seque nce comparision revealed that the orf in the sequenced region exhibits 85 % dna sequence homology with the cholesterol oxidase gene choa of streptomyces sp 对phz1754进行外切核酸酶( exonuclease ， exo )顺序缺失，获得单向长度渐减重叠的系列突变体，核苷酸序列测定显示出该ecor - sal片段的精确大小为2299bps ， frameplot程序分析揭示出该区域一个完整的开放阅读框( orf )的存在，其大小为1656bps ， g + c含量为70 . 3 ，编码552个氨基酸，利用blastsearch程序将orf的核苷酸序列及推导的氨基酸序列与因特网上基因及蛋白质数据库进行综合比较，发现无论在核苷酸水平还是在蛋白水平上，该orf均与胆固醇氧化酶表现出同源性，而且与链霉菌胆固醇氧化酶同源性最高，说明该orf编码胆固醇氧化酶基因。
Based on the engineering experience in guangzhou metro line 1 and line 2 , the schemes of mobile communication system switches in various conditions are discussed , including switching between plots in the tunnels , between upper floor and lower floor in the interchange station , between inside and outside of the interchange stations and between tunnels and floor 摘要结合广州地铁1 、 2号线工程经验，对地铁移动通信系统的各种条件下的切换方案设计进行探讨，包括隧道间小区切换、换乘站的上下层切换、站内和站外切换、隧道和地面切换等。
The main contributions of this work are included as follows : ( 1 ) numerical tests of the outside axial and helical flows were carried out respectively . the velocities and pressure profiles and shear distributions have been obtained and they were compared due to the different flow field . it is concluded that when no particles are deposited , the helical flow would lower the pressure on membrane surface to some little extent but not markedly ( 1 )对外轴向流和外切向流两种方式下膜器环隙内流场进行变参数数值实验，作出流场及切应力的分布规律，分析无颗粒沉积时层流条件下流动结构对过滤通量的影响，认为：采用外旋流的方式将对膜面压力有削弱作用，但并不明显。
1 water threatening - resistant characteristic : for instance , the outside tangency wall of epidermis cell prominently thicken ; the outside of epidermis cell are obviously covered by cuticle ; few stomats exists ; stomats are sunken ; and it has stmatic chamber structure , big aqueous tissues - parenchyma cell , mucilage cell , abnormal vascular , and soon 抗水分胁迫的抗盐结构特征。如表皮细胞外切向壁明显加厚，表皮外有明显的角质层覆盖；气孔稀少、气孔下陷及具有孔下室结构；大型贮水组织薄壁细胞、粘液细胞、异型维管束等。
