双位

In order to investigate therelationship between macrocyclic ligands and rare earth ions, wehave synthesized two new Schiff-base crown ether, two newdiaza-crown ether ligands and their rare earth complexes in thisdissertation. These complexes have been characterized byelemental analyses, IR spectra,〓 NMR spectra, thermalanalyses and molar conductivity measurement, we investigatedtheir ability to form coordination compounds and theircompositions and properties.

Two-stage matrix converteris a novel matrix converter,which developes from conventional matrix converter.Besides of adopting many ideal characteristics of CMC,TSMC also has many other merits,such as:fewer power switchings,more simplified clamp circuit,simple and reliable inversion,much simple control strategy,etc.

双级矩阵变换器(two-stage matrix converter，简称TSMC)是一种新型矩阵变换器，它继承了传统矩阵变换器(conventional matrix converter，简称CMC)的诸多理想特性，又具有功率开关器件相对较少、箝位电路大大简化、换流简单可靠、控制算法的复杂性降低等优点。

Finally, this thesis also presents an integrated design of a dual core embedded system with a 32-bit RISC, Intel?? StrongARM SA-1110, and ADSP-2181 DSP.

最后，本篇论文还提出一个基於32位元RISC及DSP的双核心嵌入式系统整合设计。

Sonograms from 6 subjects were interpreted by 2 blinded independent assessors at the time of acquisition and 6 mo later.

六份超声图样本是通过双盲的方法由两位独立的技术员在测量即刻及六个月之后分别进行分析解释获得的。

Quantitive coordinate solvent-DME was added during the preparation reaction or crystallization, sodium ion in complex 1, 2 and 4 will be extracted and become free one, thus new solvated anion-cation pair complexes [2Ln2][Na22] Ln = Nd (5, Sm (6), Yb (7) were formed.

在反应或者结晶的过程中加入一定量的乙二醇二甲醚，配合物1，2和4中与双芳氧鞠位的钠离子被DME分子萃取出来，生成阴阳离子对配合物[_2Ln_2][Na_2_2]Ln=Nd(5，Sm(6)，Yb(7)。

I saw a woman at a party recently wearing a pair of crocodile slingback shoe-boots with a large mink-trimmed tongue, and I was so taken with them that I stood next to her for quite some time relishing their glamour by proxy.

在最近的一次派对上，我看到一个女人穿了一双鳄鱼皮露跟女靴，还有个很大的用貂皮装饰的舌片（鞋子上的舌片，不是这位女士的舌头），我十分为之吸引，所以在她旁边站了好一会，用品味他们的魅力来代替。

Shuangzhu mechanical vehicle lift, which includes two box-shaped Jusheng pillar, two vertical sliding in the box-shaped piece of Jusheng-piece aircraft, two up and two track-holding arm, their identity is in Jusheng pillar box-shaped structure in part by the end of Liang-bed or carpenter's square or rectangle gear boxes and gear boxes on both sides of a square-short margin upward extension of the upper beam connecting a pillar overall; Jusheng pillar box is described below rectangle gear boxes installed electric motors is one of the driving boxes; and the piece-by-two parallel fixed in its orbit above the occasional arm-supporting, through the Hua Tao Kong spaces interlinked.
