查询词典 string band

The GaAs, InP-based III-V compound semiconductors, which are known as their wide band-gaps, direct-band transition, high photoelectric conversion efficiency and high saturated electron drift velocity and mobility, become increasingly important and have been widely used in microelectronics and optoelectronics.

The luminescence properties were investigated with PL and PLE spectra.Emission peaks were at about 450 nm.This emission was ascribed to the recombination between the sulfur vacancy-related electron trap donor having an energy level just below the conduction band and the Ag-related hole trap acceptor above the valence band.

通过发射光谱和激发光谱对产品的光学性质进行研究，发射峰位于450 nm左右，归属于硫空位相关的电子陷阱施主和银相关的空穴陷阱受主的复合；激发峰位于333 nm左右，归属于ZnS基质的带边吸收。

An excitation band at 218 nm is also observed in the excitation spectra, which corresponds to the electron transition from the ground state to the conduction band.

在其激发光谱中观测到218 nm的激发峰，这归属于电子从Mn2+基态到导带的电荷转移跃迁所致。

A new technique is presented for maximizing the band-edge selectivity of elliptic filters, and then the equal ripple parameter of the quasi-elliptic function can be calculated when the band-edge selectivities of the elliptic function and quasi-elliptic function are the same.

提出了标准椭圆函数的边带优化方法，在此基础上使标准椭圆函数与修正后的准椭圆函数在边带上的衰减相等，得到准椭圆函数的等波纹系数。

The broad excitation band and emission band can be seen from the excitation and emission spectrum .

由于Gd3+的掺入改变了基体的晶场结构，致使发射光谱发生了红移。

Every time she is performed " dance of handleless cup bowl ", our band is sure to want those who assume dance music to accompany, in the human body that can view and admire her to enchase each note of music in oneself clearly in this moment, behavioral transmission is worn musical vigor and immanent affection rhythm, then the be well versed in of whole music score that band performs is in beauty of air of her human body.

每当她表演《盅碗舞》，我们乐队务必要承担舞曲的伴奏，就在这个时候可以清楚地观赏到她把音乐的每一个音符镶嵌在自己的肌体里，动作透射着音乐的活力和内在的情感节奏，进而乐队演奏的完整乐谱贯通在她人体旋律美。。。

Type A band was detected in nearly all the organs and tissues,when coat color chimerism was over 85%, indicated the ES cellhas a fairly high potential to differentiate into cells of endoderm, mesoderm and ectoderm,In addition, only type A band was observed in the muscles of 6 mice which coat color chimerism is over 85%,the results indicated that these muscles were differentiated only from ES cells.

当毛色嵌合率大于85%时，几乎所有的器官组织都检测到A型条带，显示了ES细胞在发育形成内、中、外胚层的细胞方面具有很高的分化潜能。另外，在毛色嵌合率大于85%的其中的6只嵌合鼠的肌肉中，只观察到A型的条带，表明这些肌肉只单独来源于ES细胞。

This article briefly introduces the development from impurity engineering to energy band engineering and three methods of energy band engineering.
