In Chapter 4,further theoretical study on UWB biconical antenna and V-coni-cal antenna is presented.The theory of biconical and V-conical antenna with ellipticcross section is developed in the sphro-cone coordinate system under the assump-tion of TEM mode.

第四章研究UWB/SP的辐射天线，对双锥天线及V—锥天线在理论上作更进一步的研究，发展了无穷长双椭圆锥天线的理论提出了一种新天线结构形式-V椭圆锥天线。

Abstract〕Objective:To study the tooth size correlation between permanent cuspid and bicuspid group and other teeth groups in malocclusion.

摘要〕 目的：研究错、正常的尖牙、双尖牙组与其它组牙的相关性，为尖牙、双尖牙组的预测提供科学依据。

Results:In normal occlusion,the size of cuspid and bicuspid group was correlated with that of mandibular incisor group in accord with the principle of Moyers prediction.

结果：正常的尖牙、双尖牙组与下切牙组高度相关，符合Moyers预测机理，但错的尖牙、双尖牙组一般与同牙列的切牙加第一磨牙组高度正相关。

By the combinatorial proof or combinatorial interpretation, the identity is equipped with certain count meaning. The most general way in the combinatorial proof is to count two sides of the identity by two different methods. Generaly, through building a bijection from one set to another one, the number of the two sets respectively represents the two sides of the identity.

恒等式的组合证明或组合解释赋予了恒等式一定的计数意义，组合证明最常用的方法是分别用两种不同的方法对恒等式的两端进行计数，一般通过构造两个集合之间的双射，这两个集合的个数分别表示恒等式的两端，从而根据双射的一一对应性证明恒等式。

Moreover, by the combinatorial proof or combinatorial interpretation, the identity is equipped with certain count meaning. The most general way in the combinatorial proofs is to count two sides of the identity by two different methods. Generaly, through building a bijection from one set to another one, the number of the two sets respectively represents the two sides of the identity. Because of the 1-1 property of bijection, the identity is proved.
