The dog must present a generally gay, lively and active appearance; bone and strength in a small compass are essentials; but this must not be taken to mean that a Fox Terrier should be cloddy, or in any way coarse--speed and endurance must be looked to as well as power, and the symmetry of the Foxhound taken as a model.

这种狗的性格一般都比较快乐、活泼、有活力；较小规模的骨量和力量是必须的特征；但这并非表示猎狐梗是一种傻狗，或有任何粗糙的地方--其实，速度与耐力与力量一样重要，而且猎狐梗在猎狐类猎犬中，是匀称性的典范。

The Symmetry of the Foxhound is of the greatest importance, and what is known as "quality" is highly regarded by all good judges.

匀称性"对猎狐犬来说是至关重要的，也就是我们所知道的"品质，这是所有裁判都非常关注的问题。

The article analyzed the Franz Schubert's Piano Sonata, Op.120 all-around with the elements of multidimensional structures, such as the pitch, rhythm, and textures. It discussed the effect of change and ratio to the drive and structure of the music through the three aspects of combination: the synchronous change and symmetry ratio of the element rhythm, the asynchronies change and the asymmetry ratio of the element rhythm, and the synchronous with asynchronies changes, and compared them with the Heinrich Schenker system.

内容提要：本文以舒伯特《钢琴奏鸣曲OP.120》为例，对该部作品的音高、节奏、织体等多维音乐要素进行了综合分析，从要素节律的"同步变化"和要素节律间的"匀称比率"、要素节律的"异步变化"和要素节律间的"非匀称比率"以及要素节律的"同步变化"、"异步变化"的结合三方面，来探讨了这些"变化"、"比率"对音乐的动力、结构力的作用，并与申克的还原体系分析方法进行了比较。

The computing precision with this method is high, which is higher than 10〓 in whole complex plane and is higher than 10〓 in great majority of the complex plane. In addition, the symmetry relations of the two functions and complex zeros of Fresnel integral are studied also.

此外，本章还研究了菲涅耳积分和过度函数在复平面上的对称性、零点、变化规律等，绘出了复平面上的三维立体图和二维等值线图，使人们对这两个特殊函数在复平面上有一个清晰的直观的认识。
