Because of special geometry structure of three-cone bit, the top of formation will form a tri-spine well bottom while drilling with three-cone bit the drill string. It is the tri-spine well bottom that leads to the axial harmonic of vibration when the bit revolves a round and the three concavo-convex heave of bit and formation result in one time (1×rpm),two time (2×rpm), three time (3×rpm) turning table speed.

高岩由于三牙轮钻头的特殊几何结构，钻进过程中在岩层顶部容易形成一个三脊状井底，正是这一三脊状井底，当钻头旋转一周时钻柱轴向三次凸凹变化，由此在轴向产生1倍、2倍和3倍及其更高次倍于转盘转速rpm的谐波振动。

Experimental results show that the 3D SPEZBC algorithm has the same rate-distortion performances of three-dimensional embedded zero block coding (3D EZBC) algorithm, obviously outperforms three-dimensional set partitioned embedded block (3D SPECK) algorithm, three-dimensional set partitioning in hierarchical trees(3D SPIHT) algorithm and (AT-3D SPIHT) algorithm, and is slightly better than JPEG2000 multi-component (JPEG2000-MC) algorithm at different bit rate in the compression performances.

实验结果表明，3D SPEZBC算法具有与三维嵌入式零块编码(3D EZBC)算法相同的压缩编码性能，在各比特率下编码性能均明显优于三维集合分裂嵌入式块编码(3D SPECK)、三维等级树集合分裂(3D SPIHT)和非对称三维等级树集合分裂(AT-3D SPIHT)算法，并且略好于多分量JPEG2000编码(JPEG2000-MC)算法。

At the beginning of the thesis, the structure of usually used radome is introduced and the parameters of electromagntic characters are described in Chapter Ⅰ; the different methods for analysis of the electromagnetic characters of radome are summarized in Chapter Ⅱ; the propagation of 3-D beam in free space is conducted in Chapter Ⅲ; then in Chapter Ⅳ, the 3-D Complex Ray Theory are analyzed and the characters of transmitted field of sum and difference beams through radome are studied, and the relative formulations of calculation are rekened; at last the electromagnetic characters of the ellipsoidal sandwich radome and the plane single-layered radome are discussed, and suggestions for optimization of electromagnetic properties of radome are given.

本文第一章介绍了常用雷达罩的结构和描述雷达罩电磁特性的参量，第二章概述了目前分析雷达罩电磁特性所采用的各种方法，第三章分析了三维波束在自由空间传输特性，第四章研究了三维复射线理论，并应用它分析了单脉冲和差波束穿过雷达罩透射场的特性，导出了有关计算公式，在第五章，通过大量的数值计算和实验研究，讨论了椭球形三层夹心状实用雷达罩和单层介质平板模拟雷达罩的电磁特性，并提供了雷达罩电气特性优化的建议。

After the three stages of development theory: theoretical validation phase to verify the reasonableness of the theory; influence factors and formation mechanism of the research phase, an analysis of three factors on the effect of a third person, with the use of self-attribution theory to explain the causes of optimism bias ; new media and cross-cultural research stage, such a stage that there is this knowledge.

该理论经过三个发展阶段：在理论验证阶段，验证了理论的合理性；影响因素与形成机理研究阶段，分析了三个因素对第三人效果的影响，运用自我归因与乐观偏见理论解释成因；新媒体背景下的研究阶段，研究了这个阶段也存在第三人效果认知。

The third key-press is regarded as letter affirmance key-press on mini key-board, at the same time, identifies sound, the identical method is: identifying the three sounds by lengthways three lists, identifying the three rhymes by transverse three rows, the intersectant is the whole identifying key-press of sound.

小键盘以输入第三键作为字符确认键，同时识别声韵，识别方法是：以纵向三列键识别三声；横向三排键识别三韵，纵横交合键位就是该音节的声韵全识别键。

The story revolves aroundthree brothers who are representative of the business owners, white and bluecollar workers of Singaporeans.

故事以杨家的三兄弟为主线展开。虽然这三个人是亲兄弟，从小都在新加坡的中等阶层的家庭成长，但是这三人分别代表新加坡三个不同收入、不同阶级的人物。

The author first clarifies some theoretic misapprehensions about 'the third party in arbitration',then analyses pros and cons in depth by examining some typical cases of the Supreme People's Court and international arbitration rules and regulations,finally the author explores advantages of the system of arbitration and draws an conclusion that 'the third party in arbitration' should not be established.

其中，在理论界和实务界争论较多、分歧较大的一个问题是，除了仲裁协议的当事人，第三人能否参加仲裁？第三人原本是民事诉讼中的概念，我国1994年《仲裁法》没有规定仲裁第三人制度，其他法律法规也没有明文规定。仲裁中应否设立第三人制度，这要先从仲裁的现实困境谈起。随着市场经济的发展，社会经济结构从简单趋向复杂，社会分工也越来越细。

The development from simplex existence of three tuning systems to organic combination of three tuning systems is known as the twelve-tone-equal temperament with multi-frequency flexibility. The harmonious combinations between circle-of-fifths system and rhyme, just intonation and harmonic, and twelve-tone-equal temperament and inflexion, make up a new tuning system which takes full use of advantages of three tuning systems.
