Its a high performance , low temperature coefficient permanent magnet with its high working temperature350 degree centigrade . when working above 180 degree centigrade , its maximum energy product bh and steady temperature are superior than ndfeb magnetic materials 是由釤鈷和其它金屬稀土材料經(jīng)配比,溶煉成合金,經(jīng)粉碎壓型燒結(jié)后制成的一種磁性材料,具有高磁能積極低的溫度系數(shù),最高工作溫度可達(dá)
The studies on the nonthermal radiation of a kind of nonstationary black holes show that it owns the characteristics of direction and the energy extent of the radiation particles varies in different direction , in which aspect can get some new and meaningful results , namely the exact expressions on the maximum energy of the particle 同時(shí),對(duì)一類動(dòng)態(tài)黑洞非熱輻射的研究表明,動(dòng)態(tài)黑洞的非熱輻射具有方向性,在不同的方向上,非熱輻射粒子的能量范圍不同,在這方面得出的非熱輻射粒子的最大能量的精確表達(dá)四) i大學(xué)博士學(xué)位論文式等內(nèi)容都是創(chuàng)新的和有意義的結(jié)果。
For two up and down plunging jets , an optimization model is introduced according to maximum energy dissipation . in this model , the exit angle of jet is first considered actually . the optimal computation of the energy dissipation between two impinging jets in xiao - wan project demonstrates that this model is reasonable too ; 6 對(duì)于上、下雙股挑流水舌,以碰撞消能率為優(yōu)化目標(biāo),首次考慮了出口水舌的坦化影響因素,建立了優(yōu)化數(shù)學(xué)模型,并通過(guò)對(duì)小灣拱壩壩身表、中孔水舌的碰撞計(jì)算,認(rèn)為所提出的數(shù)學(xué)優(yōu)化模型是可用的; 6
The migration results of the synthetic and ocean field datasets show that this method is correct and effective . several prestack depth migration methods are proposed and unified to the synthetic source record migration method . these methods include plane wave migration with fourier finite difference ( ffd ) extrapolator , maximum energy plane wave migration and prestack migration with phase encoding of areal shot records 通過(guò)對(duì)本文提出的平面波傅立葉有限差分疊前深度偏移方法、最大能量面炮記錄疊前深度偏移方法和相位編碼面炮記錄疊前深度偏移方法的研究,試算和對(duì)比,提出了合成震源三原則,根據(jù)這些原則,提出了合成震源概念和合成震源記錄疊前深度偏移方法。
There is extremely high passion about new technology , and like that accept new stump , andhas irritableness about force of development the future and forecasts force ; creativity reason that was rich , is cheerful , and person coming and goingexcellent and come , file business ability is strong ; is directive in ability having fixed rank and file and amalgamate , and exert maximum energy to ranks ; vigor is high , and there are positiveness and sense of responsibility strong work . believe your line of vision , and by luster that i am dazzling certainly yet 對(duì)于新技術(shù)有極高的熱情,樂(lè)于接受新的挑戰(zhàn),并對(duì)于未來(lái)發(fā)展趨勢(shì)有著敏感的洞察力;富有創(chuàng)造性思維,性格開(kāi)朗,善于與人交往,團(tuán)隊(duì)工作能力強(qiáng);具有一定的團(tuán)隊(duì)領(lǐng)導(dǎo)和融合能力,使團(tuán)隊(duì)發(fā)揮最大的能量;精力充沛,有強(qiáng)烈的工作積極性和責(zé)任心。
