从“曹振镛现象”透视封建政治文化特征

历史上对于晚清颇受道光皇帝重用的汉人大臣曹振镛历来批评较多,甚至认为他是＂庸官＂的代表,对晚清腐败的官场习气应负重要责任。研究认为曹氏为官之道中有消极成分,然在封建社会有其适用性,把中国封建社会末期腐败的官场习气简单的归罪于曹振镛个人有失公允。应该从中国封建专制制度和儒家传统文化出发,以探求＂曹振镛现象＂产生的深层社会原因。     

Eye-Safe Raman Laser at μm Based on BaWO4 Crystal

Using an external couple cavity and a pump beam compression system, efficient 1.5 μm eye-safe Raman laser is obtained based on BaWO4 crystal. The largest output energy is 8.5mJ, corresponding to an electric-optical conversion efficiency of 47%.     

曹操家族血源考论

目前学术界关于曹操出身的争论,焦点集中在姓曹还是姓夏侯上面,源自曾氏本家之说存在诸多疑点,而源自夏侯氏证据更充足,从陈寿《三国志》行文体例及裴松之注的多处内容来看此说可以得到证实,曹嵩后代对曹腾的态度也或许可以说明问题,还有,考察曹丕和夏侯氏诸人的特殊关系对认识问题真相也有帮助。封建社会血统决定一切,名不正则言不顺,统治者出于维护正统的政治形象和封建宗法纲常的需要,这是史书没有明确记载曹魏血源的原因。     

Minimization of finite beam effects in the determination of reflection and transmission coefficients of an elastic layer

A special data acquisition technique was applied to determine the acoustic plane-wave reflection and transmission properties of a plane-parallel aluminum plate. In this technique, the reflected and transmitted wavefield along a plane or line normal to the reflected or transmitted wave vector is recorded at equidistant receiver positions. The obtained traces are subsequently added up in the temporal domain to satisfy plane-wave conditions, thus effectively removing the effect of the limited beam of commonly used transducers. The agreement between plane-wave theory and experiment was found to be excellent, both in the temporal and in the frequency domain.     

Measurements of velocity and attenuation of leaky waves using an ultrasonic array

A new method of measuring velocity and attenuation of leaky surface waves is presented. A single focused transmitting transducer and linear receiving array in a pitch-catch arrangement are used in the proposed system. The spatial distribution of the acoustic field in the leaky wave is recorded by the array, and the parameters of the leaky wave can be obtained by processing the output waveforms. In comparison with existing material characterization systems, the mechanical scanning of the transducers is not used any more, and the measurement time is only limited by the time of the wave propagation and speed of the electronic data acquisition system.     

微波消解-氢化物发生-流动注射原子荧光光谱法测定犁头草等中药材不同部位的硒

用微波消解-氢化物发生-流动注射原子荧光光谱法测定犁头草、淫羊藿等中药材中硒的含量,并比较测定了各品种不同部位的硒含量差异,对样品处理、干扰消除等进行了探讨,结果表明,本法回收率为95.35%—102.90%,方法的选择性好,操作简单,适用于常见中药材中微量硒的检测。     

曹丕才非“去植千里”

对于曹丕、曹植兄弟文学成就的评价,论者较普遍的观点是抑丕扬植,认为曹丕文才“去植千里“。笔者辩证地对曹丕进行了较全面的分析和考察,认为在文学上,尤其在文学理论方面,曹丕比曹植走得更远,更富开创精神,在中国文学史上做出了卓越的贡献。     

从《全清词钞》看叶恭绰的词学观

叶恭绰先生编的《全清词钞》是收录清词最多的选本。作为一个选本,编者在弃取之间就有一个标准,那么这个标准又是什么呢？通过对《全清词钞》的粗略阅读,大概得出以下几点：标榜抒写胸臆,率尔而作,反映重大现实题材;主张革新词之格律,提出“能合乐、有韵脚、雅俗能共赏”的新词律观;并且在《全清词钞》的编辑过程中,努力实行其“搜罗宏富、审慎精严”的词学文献观。     

叶适易学思想发微

叶适是循义理的路数来解<易>的.具体说,就是根据<彖><象>解<易>.由于他将<彖><象>视为孔子的作品,所以根据<彖><象>的解释所理解<周易>的经义,在他看来,也就是"孔氏之本学",体现了圣人以道易天下的目的.在这种易学观的指引下,他之<周易>解释,在致思取向而上,彻底贯彻事功原则、功利原则,竭力消解<周易>解释上的神秘性、玄虚性,始终坚持"以卦象定入德之条目而略于爻,又以卦名通世故之义训而略于卦".这是将"通世故之义"作为理解<周易>的经义根本原则.这个原则从根本上保证了叶适之解<易>彻底摆脱了象数路数的干扰,将<周易>解释成为一部彻底宣扬儒家的德性修养、道德理想、政治理念的经典.
