Great comic artists assume that truth may bear all lights, and thus they seek to accentuate contradictions in social action, not gloss over or transcend them by appeals to extrasocial symbols of divine ends, cosmic purpose, or laws of nature.

尽管这些分子能够透过可见光，阳光的大部分热量？都集中在这个波段，但是它们吸收长波，从地表来的红外辐射，或者将有些辐射折射回空中。

According to the Russian archives revealed in recent years and the recollections of the Soviets concerned,the article makes an objective analysis of the historical background,causes of the events and the leaders'motives,ways to deal with the disputes.The author indicates that although the Soviets displayed great-nation chauvinism to a certain degree,yet they had not the intention to violate China's sovereignty.While Mao Zedong forced Nikita Khrushchov to give in by making extremist response to these questions,he created psychological obstacles for further cooperation between the two countries.The original reason of their unconsummated military cooperation was the inherent unstability within the socialist alliance.

引用近几年披露的俄国档案文献及苏方当事人的回忆，文章对上述事件的历史背景、原由以及两国领导人处理问题的动机和方式进行了较为客观的分析，认为实现军事合作是中苏双方的愿望；苏联在与中国交往中确有某种程度的领导者心态，但并没有任何侵犯中国主权的意图；在长波电台和联合舰队问题上，毛泽东作出过激反应，其结果虽然迫使赫鲁晓夫屈服，却给中苏进一步的军事合作制造了心理障碍；中苏最终未能实现军事合作的根源在于社会主义阵营同盟关系内在的不稳定性。

I.! y P,{7 v: R; O0 D INTRODUCTIONIn most of the previous studies like [1-3], the effect of SRS in DWDM fiber opticsystems has been treated under various assumptions like undepleted pump approximation, wavelength independent fiber loss coefficient, triangular approximation of Raman gainprofile, negligible loss of energy whenever a short wavelength photon is transformed into a long wavelength photon (i.e., l i / l k ~ 1), equal power loading in all the wavelength channels and equal channel spacing.

P _ W/ I 在以往的绝大多数研究中，如[1-3]，人们都认为， SRS 在 DWDM 光纤系统中的影响是在诸多假设，如未衰减泵近似值，波长依赖光纤损耗系数，喇曼增益表的三角近似值，当短波光子被转变为长波光子时(i.e。， l i / l k ~ 1可忽略不计的能量损耗，各波长通道均等的动力负载以及均等的信道的频率间隔。
