凄凉哀怨的遗民心声--论汪元量词的内容分类与艺术风格

考察汪元量词的内容题材，大致可分为祝寿词、闲适词、咏物词、友情词、别情词、乡情词、咏史词、感慨词、恋情词九类。从人、境、情三个审美层次看，汪词里的抒情主人公与作者在相当程度上是重叠关系；境呈现个体生活场景与历史空间的二元组合的面貌；情则是民族悲愤与个体生存苦闷的双重变奏曲。汪词的主体风格是沉郁衰飒、坦直真率、清丽淡雅、晓畅明白。     

解析Photoshop中的"色阶调整"

photoshop中的“色阶调整”命令可准确地对图象进行亮度、对比度和色调调整，但这一命令涉及的概念较多，且较难理解。本文结合实际操作对该命令及相关内容进行了详细的解析。     

物理实验的分层次有限性开放研究和探索

开放的大学物理实验对培养学生创新能力和综合素质具有重要作用，同时也面临着很多问题和困难；要做好实验的开放工作，必须进行认真的研究和探索，要根据实际情况，遵循开放和传统相结合的原则，分层次有限性的开放。文中进行了一些有益的探索和实践。

分子轨道图形理论中对称轴定理的明确和扩展——(Ⅰ)本征多项式分解定理

本文对唐敖庆教授和江元生教授等人确定的对称轴定理作了一定的扩展,并以比较浅显明确的形式描述了对称轴定理。扩展后的对称轴定理不仅可以将具有Cn轴的共轭分子的本征多项式分解为n个因子相乘的形式,而且可以直接得到π分子轨道的解析表达式。

Effective adjustment of the optoelectronic properties of organic conjugated materials by synthesizing <Emphasis Type="Italic">p</Emphasis>-<Emphasis Type="Italic">n</Emphasis> diblock molecules

Because organic conjugated materials offer several advantages relative to their inorganic counterparts,the development of organic conjugated materials has been one of the most active research areas in optoelectronic materials.For almost two decades,the search for organic conjugated materials has represented a major driving force for research concerned with controlling the band gap of extended π-conjugated molecules.In particular,among the parameters affecting the performance of organic light-emitting diodes (OLEDs),the energy levels of organic conjugated materials play an important role because they can affect the driving voltage,wavelength,efficiency,and lifetime of the final device.Balanced injection and transport of electrons and holes are therefore crucial for achieving OLEDs with high quantum efficiency.In this regard,research into adjusting the energy levels of organic conjugated materials is very meaningful for the development of OLEDs.To adjust the energy levels of the organic conjugated materials,Huang et al.have presented a new molecular design and synthesis route that yields p-n diblock conjugated copolymers and oligomers.The present review summarizes and analyzes the progress on adjusting the optoelectronic properties of organic conjugated materials that is due to synthesizing p-n diblock molecules.We discusses primarily work done by Huang et al.,but also discusses work done elsewhere over the past few years.We also point out issues that require attention,and highlight hot spots that require further investigation.     

不同密度与施氮水平对大豆产量及产量性状的影响

为探讨密度与施肥对大豆产量及产量性状的影响,采用裂区试验设计研究了吉育35在不同密度与施氮水平下的产量及产量性状.结果表明:密度对单株荚数、单株粒数、单株荚重的影响均达到显著水平,随密度增加,单株荚数、单株粒数、单株荚重降低.施氮对单株荚数、单株粒数的影响达到显著水平,随施氮量增加,单株荚数、单株粒数增加,施氮对单株荚重影响未达到显著水平.密度与施氮对百粒重的影响均未达到显著水平.密度与施氮对产量的影响均达到极显著水平,随密度增加,产量先增后降,随施氮量增加,产量增加.密度为220000株·hm-2、施氮量为90kg·hm-2处理的产量最高.
