The measurements used are fork length , head length , upper jaw length , snout length , length of dorsal fin base and anal fin base and the distances from the tip of snout to insertion of dorsal fin , to pectoral fin , to ventral fin and to hard margin of preopercle 此所用于分析之外部非体节形质计有：尾叉长、头长、上颚长、吻长、眼径、背鳍基底长、臀鳍基底长以及吻端到前鳃盖骨后绿、背鳍起点、腹鳍起点、臀鳍起点等11个形质。
In consequence of a family complex he has temporarily lost his memory and i believe him to be more sinned against than sinning . i have made a pervaginal examination and , after application of the acid test to 5427 anal , axillary , pectoral and pubic hairs , i declare him to be virgo intacta 我相信他是个并没有犯多大罪，却受了很大冤屈的人299我曾对他做过全面检查，对肛门腋窝胸部和阴部的五千四百二十六根毛做了酸性试验。
I will activate the air ( qi ) around my pectoral muscle by doing 77 push - ups in one hand before massage , i use my big and elastic pectoral muscle to massage the acupoint of customer ' s foot with qigong for beauty , dispelling worries , refreshing or slimming 理疗时我先用左右手各单手做77个俯卧撑进行运气，并分别将气发到我的左右胸肌上，再用硕大强健且富有弹性的胸肌点穴按摩被疗者足部的有关穴位，从而达到美容、解闷、去烦、提神、减肥及健身的作用。
Based on the " fangsheng - i " robot fish of harbin engineering university auv lab , at first the analysis of the relations of pectoral fin ' s attack angle and lift in vertical plane is done in this paper , using the robot fish ' s hydrodynamic results by the panel method ' s , then setting up the motion model in vertical plane is done . finally animation the robot fish ' s motion in horizontal plane is finished 论文以哈尔滨工程大学军用智能水下机器人国防重点实验室的“仿生? ”号仿鱼机器人为对象，利用面元法计算的仿鱼机器人水动力结果，并分析了垂直面内胸鳍的攻角与升力的关系，建立了垂直面内的模型，根据轴变形模拟了仿鱼机器人水平面内的直航和偏航。
The test proves that the caudal fin oscillation frequency , the maximum amplitude of vibration of caudal fin , the caudal fin strikes the water angle influence the fish ’ s speed ; the curve experiment has obtained curve radius of inertia advance curve and static curve ; the ups and downs experiment proves that the pectoral fin on different angle influences the fish to move ups and downs 加减速试验论证了尾鳍摆动频率、尾鳍后缘最大摆幅以及尾鳍的最大击水角度对鱼体速度的影响;转弯试验测得了机器鱼惯性前进转弯和静止转弯时的转弯半径;在机器鱼的升潜试验中论证了胸鳍不同转角对升潜运动的影响。
Through the fundamental academic research of tunny ’ s swimming mode , the single motor - driven - robot fish has been designed , which has two joints taking pectoral fins as an elevator to make the fish - like robot moving up and down , moreover it can achieve the inertia swerve and the static swerve 通过对?科加新月形尾鳍推进模式鱼类的仿生学研究,设计了单电机驱动两关节联动的尾鳍推进仿生金枪鱼,以胸鳍作为升降舵实现机器鱼的上浮和下潜,还可实现惯性前进转弯和静止转弯。
Diagnostic characters for the recognition of species include the presence or absence of pectoral fin , the position of dorsal fin origin , gill opening , anus , nostril opening and eye , the cirri present or not , the dentition type , the body coloration , and the head pores or lateral line etc 一般依据胸鳍的有无或发达程度，背鳍起点、鳃孔、肛门、鼻孔和眼等的相对位置，颌的发达程度和颌上是否具须，齿的形状和排列方式，身体的斑纹，以及头部和体侧的侧线孔数目等进行鉴别。
He unbuttoned successively in reversed direction waistcoat , trousers , shirt and vest along the medial line of irregular incrispated black hair extending in triangular convergence from the pelvic basin over the circumference of the abdomen and umbilicular fossicle along the medial line of nodes to the intersection of the sixth pectoral vertebr aelig ; , thence produced both ways at right angles and terminating in circles described about two equidistant points , right and left , on the summits of the mammary prominences 然后又反过来自下而上地依次解开背心长裤衬衫和内衣纽扣。他那双手的轨迹从参差不卷缩起皱的黑色体毛的中心线也就是自骨盆底到下腹部肚脐眼周围那一簇簇体毛，又沿着节结的中心线进而延伸到第六胸脊椎的交叉点，从这里又向两侧丛生，构成直角形，在左右等距离的两个点，即环绕乳头顶端形成的三角形收敛图形的中心线穿行。
