Actually, the development of genetically-modified products is a double-edged sword: On the one hand, it contributes to the enhancement of the world crop yield, as well as the quality, and reduction of chemical fertilizer and the pesticide use, helps solution of the famine and undernourishment in developing countries. Besides, it also promotes the development of certain related industries like pharmaceutical and chemical industries; On the other hand, it also brings the unprecedented threat for human beings. We are unaware of the potential effects in human bodies, or any unknown injury to the next generation, caused by genetic modification. Nor can we forecast what kind of influence to the extant gene will emerge.

而事实上，转基因生物技术的确是一把双刃剑：一方面，转基因技术可以提高世界农作物产量、提高质量、减少化学肥料和杀虫剂的使用、解决发展中国家的粮食缺乏、饥饿和营养不良的问题，另外，基因技术的飞速发展在很大程度上也促进了医药、化工等相关行业的发展；另一方面，它也为整个人类带来了前所未有的威胁，人们无法得知基因序列的改变会在体内引起何种潜在的变化，无法确定转基因产品是否会对下一代产生任何未知的伤害，无法预测转基因产品对现存基因会产生何种影响。

These findings indicate that SUMO modification of CBP and subsequent recruitment of Daxx and HDAC2 represents a previously undescribed mechanism in modulating CBP transcriptional potential.

综合以上发现，我们认为类小泛素修饰CBP会促使Daxx及HDAC2与之相结合进而抑制CBP的转录活性。

There are three advantages of our study. 1. We embedded the watermark by frequency domain and created unexpanded shares, which reduced the impact of pixel modification effectively.

本研究的优点有三个：一，我们的方法以频率域的方式嵌入浮水印，产生不扩展的分享影像，降低了像素值易受攻击的影响。

The modification of energy-conversion technologies represents perhaps the greatest unexploited potential for the rural Third World.

能量转换技术的修改也许代表着第三世界城市的巨大开发潜能。

This thesis makes the analysis of the methods of frequency measurement,which is the main function of the universal counter,and decides to use the gate modification method to measure frequency.

本文对计数器的主要功能之一，频率测量方法进行了分析，提出采用闸门时间修正法进行测频，降低了量化误差的影响。

A form of post-transcriptional modification to mRNA in eukaryotes in which cytosine is deaminated to form uracil.

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。

This is the essential thing: that Western man has been drawn for three centuries to the task of telling everything concerning his sex; that since the classical age there has been a constant optimization and an increasing valorization of the discourse on sex; and that this carefully analytical discourse was meant to yield multiple effects of displacement, intensification, reorientation, and modification of desire itself.

这就是西方人三个世纪以来，被牵引着坦白有关于性的一切事情的真相；是古典时代以来，性话语不断优化，稳固增长的真相；而且这种经过审慎分析的话语意味着可以产生出置换，强化，重取向，以及欲望自身的变型等多重效用。
