可以把这种方法应用到在等离子体物理和天体物理中经常遇到的柱对称或球对称的光学薄的等离子体上。

Furthermore, all solutions obtained are non-radially symmetric. The second part of the thesis studies a type of elliptic equations with singular coefficient i.

与以前工作不同的是，尽管问题具有径向对称形式，本文所给出的这些解都是非径向对称的。

In this paper,a new method of measuring the resonant frequency of the RLC parallel resonance circuit was intro- duced,which makes the asymmetric amplitude-frequency curve symmetric.

介绍了用Origin变换坐标，将不对称的RLC并联电路的幅频特性曲线对称变换，从而精确求解其共振频率的方法。

A series of novel dicationic symmetrical and asymmetrical ionic liquids based on tributylalkyl phosphonium and alkylimidazolium were synthesized.

合成了一系列含有三丁基烷基膦盐和烷基咪唑盐的对称的和不对称的双离子液体。

A half of a symmetrical, approximately spherical object as divided by a plane of symmetry.

Our machine adopts level principle. The symmetrical roller assembly is connected by horizontally placed spring rod. When the large material touches the roller assembly, to keep balance, the radial force may pass to the roller assembly which is plane of symmetry through spring rod. Under this condition, the whole device's bearing is improved about 40% than that of others; the forming resilient connection can reduce the vibration and noise, and avoid resonance.

该机采用杠杆原理，将对称的磨辊总成用水平放置的弹簧通过拉杆连接在一起，当大块物料顶摆一个磨辊总成时，其径向力可通过弹簧拉杆传给对称面的磨辊总成来平衡，此条件下，装置的整体受力点和其它产品相比提高了40%左右；而弹性联结装置则减轻了振动和噪音，避免了共振。

The tooth spaces of the sprocket can be symmetric, asymmetric and the root surface can be relieved.

链轮的齿间可以是对称的、非对称的，并且齿根面可以减少。

The results show that most flows with zero pressure difference are symmetric, but tiny pressure difference will make the flows between upper and lower channel asymmetric.

其结果发现，当出口处无压差时，流场大部分呈现对称的状态；而当有压力差时，则会造成上下方流道内的流场，出现不对称的现象。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
