In a study of nineteen sets of twins who had been separated from birth,investigations found that in approximately two thirds of the sets there were no more significant defferences than existed among unseparated pairs of twins.

大约三分之二的双胞胎之间的差异并不比未分开抚养的双胞胎之间的差异显著。上述句子形式上都是肯定的，但是意义上却是否定的。第一句通过free词缀实现否定意义，第二句通过no …… more than来实现否定意义。像这类句子就叫做暗否定。一般情况下，英语句子中的暗否定可以通过句子、短语和词来实现。

Took the lead through the Shanghai Testing Center of the six types of four pairs of unshielded permanent link system testing.

采用双绞线的电缆有屏蔽的，也有非屏蔽的。

VDSL is a promising technology of unshielded twisted pairs in the public telephone network for the purpose of broadband access.

It starts from Foucault's key word "historical a priori", and focuses on three qualities of "statement", with a main purpose to explain how his archaeology of knowledge, in order to overcome three pairs of antimony in traditional philosophy, that is, the empirical/the transcendental, the cogito/the unthought, the retreat of origin/the return of origin, combines pure description of discourse with an effort of exploring a priori rules of discursive formation.

文章从"历史先天"这一关键词出发，阐述福柯的知识考古学如何将对话语的实证描述和探索话语构成的先天规则结合起来，从而保证其在对话语的形式分析的同时，超越传统哲学深陷其中的三对矛盾："经验－先验"、"我思－未思"、"本源的隐退－回归"。

In this thesis an attempt is made to explore the problem of one of the pairs---Translatability and Untranslatability.

作者只把翻译中的一对矛盾作为本文的研究对象---可译性与不可译性。

The distribution of gear's contact stress, root stress, and contact engagement line in the engagement situation of gear pairs, were obtained on the base of explicit integration method. 3. Adopting the method of system matrix, the torsional vibration differential equation of general shafting was gained. The simple harmonic forms of excitation torque under the normal combustion or piston flameout of in-line engine and v-type engine were analysed. The decoupled algorithm of free vibration and forced vibration and the solution to the vibration damper's energy of resistance and the off-resonance calculation were studied. The sensitivity formulations of the natural frequency and vibration mode to physical parameters of system were derived by solving the eigenvalue problem. These sensitivity formulations provided the theoretical base for the dynamic modification of structure.

运用系统矩阵法建立了轴系的扭振微分方程，并对直列和V型发动机在正常发火和气缸熄火工况下的激振力矩进行了详细的简谐分析；基于精确方法推导了自由振动和强迫振动的解耦算法，给出了能量法计算中的减振器阻尼功求解和非共振计算方法；并研究了曲轴系扭振非线性分析中的变惯量问题，得到了单缸转动惯量的精确求解公式以及变惯量和固有频率的关系式；最后，从特征方程和振型正交性出发，推导了固有频率和振型对轴系转动惯量和刚度等物理参数的灵敏度，为扭振系统的结构动力学修改提供了理论基础。
