The electromagnetic properties of the interface between a left-handed material and a conventional nonlinear material were investigated theoretically and numeric
A new polyvinylalcohol-based photopolymeric holographic recording material has been developed. The recording is obtained by the copolymerization of acrylamide a
An anti-symmetric loop algebra A2 is constructed. It follows that an integrable system is obtained by use of Tu’s scheme. The eminent feature of this integrabl
A complex optical model potential modified by incorporating the concept of bonded atom, with the overlapping effect of electron clouds between two atoms in a mo
The folding dynamics and structural characteristics of peptides RTKAWNRQLYPEW (P1) and RTKQLYPEW (P2) are investigated by using all-atomic simulation procedure
唐有「新闻」一词,指新的知识领域。宋赵升《朝野类要》卷四:「……故隐而号之曰新闻。」《红楼梦》第一回:当下雨村见了士隐,忙施礼陪笑道:「老先生倚门佇望,敢街市上有甚
The diffusion mechanism of Li ion in a copper thin film is investigated from first-principle calculations. The energy barriers for possible spatial hopping path
玉/苕套作代表了西南地区甘薯栽培的主要模式,套作中甘薯以平作、垄作和堆作为主。就甘薯起垄方式的研究来看,关于垄作的研究较多,而堆作甘薯则较为少见;研究表明堆作具有较垄作增产的优势,但其增产的生理机制尚不清楚,究竟是垄作还是堆作更适合本地区甘薯生产尚无定论。考虑生产实际,为了提高土地综合生产效益,探讨玉米套作模式下更适于本地区的、相对高产的起垄栽培模式,本试验以当地主栽玉米品种‘西大985’和短蔓型
By a model of atwo-level particle coupled with boson field, we made it clear that an evolution problem can be solved beyond the rotating wave approximation. We
Er3+-doped lead chloride tellurite glasses were prepared using the conventional melting and quenching method.The absorption spectra were measured and the Judd-O
