Shinty is a fine free game, much less restricted by rules but otherwise not unlike hockey which is derived from it.

简易曲滚球是一种不错的游戏，没有那么多繁琐的规则约束，它在其它方面和冰上曲滚球没什么两样，其实后者就是由前者发展而来。

His sinker is considered to be one of the best in the league right now by many hitters and catchers.

He's increasingly mixing in pitches and isn't just relying on his sinker.

他增加了变换的球种而不再只依赖他的伸卡球。

Knowledge of tungsten anode X-ray tube spectra is essential for X-ray dose control, X-ray image quality evaluation and dual-energy X-ray imaging etc. A model-based tungsten anode X-ray tube spectrum reconstruction method is presented in this paper.

X射线球管光谱信息是进行X射线曝光剂量控制、X射线成像质量评估、X射线双能量成像等必不可少的，为此本文提出一种基于模型的钨靶X射线球管光谱重建方法。

In this paper the aberrations of a sort of sphere lens with spherical Symmetrical gradient index have ben analysied.

本文分析了一种折射率为球对称梯度分布的球形透镜的像差，得到了该透镜对无限远物点的纵、横向球基及其焦距的精确表达式。

Explosive expanded sphere is an advanced technology for forming thin-wall spherical shell.

爆炸胀球技术是一种成形薄壁球壳的先进技术。

It is well known that problems of vibrations of spherically isotropic(a special form of transversely isotropic)spherical shells are moredifficult to deal with than those of the isotropic ones.

由于包含五个弹性常数，球面各向同性(属横观各向同性的一种特殊形式)球壳振动的研究要比各向同性球壳振动的研究复杂。

Using medium with high concentration of serum could yield a certain amount of tumor spheroid cells.

高浓度血清培养能获得一定数量的肿瘤干细胞球，用Percoll液分离纯化肿瘤细胞球是一种简便的好方法。

It is an overhead pass used to change the direction of the dig and put the ball in a good position for the spiker.

这是一种过顶传球，用于改变垫球的方向，并将球调整到一个方便扣球手的有利位置。

Firstly, the developing principles of the cylindrical internal helical gear are proposed through analyzing the movement and geometry requirements, which provides continuous contact between the mating gear surfaces. The tooth surface of the internal helical gear in the new gearing can be imagined as being generated by the normal section of the conjugated surface of the ball-tooth, moving along the radial projection of helix line of the tooth-root circle. Also, the proposed surface can be approximate tangent to the conjugated surface of the ball-tooth along a spacial curve.

首先，通过分析保证行星轮作螺环运动时与内斜齿轮实现连续啮合传动的运动和几何条件，提出了圆柱内斜齿轮齿面的两种形成原理：即由球齿运动包络曲面的法截面沿其齿根圆螺旋线在径向的投影进行拓展所形成的内齿面，以及与球齿运动包络曲面呈近似相切接触的等螺距齿面构成的内齿面。

The split between the two groups can hardly be papered over.
