隙的

Photophysics and electroluminescent characteristics of poly, copolymers from silafluorene and fluorene and copolymers from silafluorene and phenylene are systematically studied.

系统研究了宽带隙共轭聚合物聚硅芴、硅芴与芴共聚物、硅芴与苯撑共聚物的光物理特性和电致发光特性，探索了提高器件性能的途径。

From comparison with poly(2,7-fluorenylene), the 1,2-bis( p -phenylene)-1-cyanovi- nylene unit was found to be a good electron-withdrawing moiety for electronic materials and the incorporation of 1,2-bis( p - phenylene)-1-cyanovinylene resulted in a narrow band gap and a red shift of both the absorption and photoluminescence emission peaks.

通过与聚芴对比，发现对于电致发光材料来说，由于氰基的强吸电子能力使得氰基亚乙烯基成为一个很好的吸电子基团，与之结合使得能隙变窄，吸收和发射光谱发生红移。

The comparison of theory withreported positron experiments implies that there is a linear relationship between the energygap and temperature.

将理论计算与已有正电子实验结果进行了系统的比较，观察到高温超导体中的能隙与温度间存在线性关系。

In this paper, the special structure is introduced from the viewpoint of the high power density.

其特点在于：电机的密度高，气隙磁场的方波形状好。

We also show that the long wavelength gap of the inter-subband mode is proportional to the energy spacing between the ground and the first excited energy levels △〓 rather than to 〓.

还发现带间等离激元模的长波能隙正比于基态与第一激发态之间的间距△〓，而不是与〓成正比。

The results suggested that polys had smaller band gap relative to the their homopolymers, due to the coexistence of aromatic and quinoid form and the lower LUMO energy levels.

结果显示相对於其单聚合高分子，异芳香环次甲基共轭高分子有较小的能隙是因为aromatic 和 quinoid 型态能够在共轭鍊上共存，或者是因为拥有较低的LUMO能阶所导致。

The changes of soil pH, the oxido reductase activities had no significant trends.

林隙土壤的pH、过氧化氢酶和多酚氧化酶没有明显的变化规律。

The simulation considering the competition of the band filling effect and band-gap renormalization effect is in a good agreement with our experimental results.

理论上，考虑带填充效应和带隙重整化效应的竞争，模拟得到与实验谱线相符合的结果。

At the sound of those who taunt and revile, at the sight of the spiteful enemy.

因我听到侮慢与欺凌者的声音，又面临仇敌和寻隙报复的人民。

This paper discusses a new meshing scheme about armor-piercing core and sabot of long rod AP, which adopts the structure of variational tooth clearance.

本文探讨了杆式穿甲弹的一种弹芯与弹托的新型啮合方案，即采用变齿隙结构方案。
