Each is a filiform cell up to 30 μm long and 1 μm in diameter, being symmetrically tapered at each end to produce a 'javelin-shaped' configuration.
      
Finally, I trace the development of the multi-purposed javelin, from its meager beginnings as a stick, in order to illustrate scenario visualization in novel tool manufacturing.
      
In competitive sports the vertebral column is extremely strained in several disciplines like gymnastics, javelin throwing or weight lifting.
      
Millions of artificial fry are bred annually in the species of black porgy (Sparus macrocephalus), Russell's snapper (Lutjanus russelli), javelin grunt (Pomadasys hasta), miiuy croaker (Miichthys miiuy) and skewband grunt (Hapalogenys nitens).

This paper explicates the theory of the javelin projectile falling point with the formation and the shape characteristic of the javelin projectile and suggests the prerequisites of its falling down to the ground. It also studies the best and suitable position a referee should choose to observe the course and style of flying to improve the determination of the falling point.

本文根据标枪结构、形状特点,阐明了标枪尖触地的理论及先触地的前提条件。为了公正、准确判断标枪尖触地问题。本文还研究了裁判员应选择的最佳位置和如何观察标枪飞行及落地方法。

Optimal initial conditions for javelin performance under the new rules were studied by means of computersimulation. The differences of the aerodynamic forces and moments between new and old javelins, measured inwind tunnel tests, were analysed. The relations among the initial flight angle, the initial angle of attack and theinitial angular velocity are analysed using contour maps. The sensitivity of each initial condition was discussedA practical set of optimal initial conditions was thus provided...

Optimal initial conditions for javelin performance under the new rules were studied by means of computersimulation. The differences of the aerodynamic forces and moments between new and old javelins, measured inwind tunnel tests, were analysed. The relations among the initial flight angle, the initial angle of attack and theinitial angular velocity are analysed using contour maps. The sensitivity of each initial condition was discussedA practical set of optimal initial conditions was thus provided for javelin throwers.

本文使用计算机模拟的方法,并根据新规则研究了男子标枪飞行的最佳初始条件组合。根据风洞实验的气动力和力矩分析了新、旧标枪的差异。用等高线图分析了出手角度、初始攻角和初始俯仰角速度之间的关系,并讨论了各初始条件的敏感性。为标枪运动员提供了有实际意义的最佳初始条件组合。

Applying the wind-channel experiment and the method of computer simulation, the best angle of release and the angle of attack in woman javelin were examined. Correlation between the two angles was analysed. Based on the models of two kinds of release velocity and their corresponding angles of release, the best angle of release with javelins different in metric grade was calculated and the throwing method was suggested.

本文采用风洞实验和计算机模拟的方法,对女子标枪的最佳出手角度和初始攻角进行了研究,分析了出手角度和初始攻角的对应关系.根据两种出手速度和出手角度的模型,对女子标枪运动员使用不同米级女子标枪的实际最佳出手角度进行了计算,提出了投出实际最佳出手角度的方法.
