查询词典 relaxation methods

Using semidefinite programming relaxation and randomized rounding, we give the corresponding polyniomal approximation algorithms for some NP-hard combinatorial optimization problems.

STUDY DESIGN.: A prospective cohort study evaluating the quantitative lumbar flexion-relaxation phenomenon, measured with surface electromyographic signals from the erector spinae during trunk flexion pre- and postrehabilitation, in patients with chronic disabling occupational lumbar disorders. OBJECTIVES.

研究设计：评价慢性职业腰椎疾病患者量化腰椎屈曲松弛现象的前瞻性队列研究，通过测定患者康复前后躯干俯屈时竖脊肌的表面肌电信号来反映QLFRP。

Then, various instruments such as hand drum, rawap, qalun dulcimer and ghijak, a round-bodied spike fiddle, are played as the performers sing happily in loud voices in succession. Each sings in a unique way, but as a whole the song is harmonious with alternating tension and relaxation, which forms the in spiring polyphonic effect.

接着，各件乐器手鼓、热瓦甫、卡龙琴和艾切克等竞相动情演奏，各位歌手竞相引吭高歌，他们之间互不跟调、各自为政，但是从总体上听又张弛有度、和谐统一，形成了极富感染力的多声部音乐。

Although the Japanese used hair or silk woven into the middle of some relaxation of the strainless template business card printing and membership card making, but screen business card printing and membership card making development originating from the United States.

虽然日本人最早搁置头发或蚕丝织不败的洋间有些败坏的无压力模版举行制卡和会员卡制息，但是传统丝网制卡和会员卡制息的不败长发源于美国。

After good relaxation and rest, stude will work harder.

休息好和放松后，学生会更加努力学习。

The results of Knight shift and spin-lattice relaxation time (T1) provide us that there are no correlation between the density of states at Fermi level and the superconductive transition temperature of the studied material.

藉由奈特位移及自旋晶格松弛时间的量测结果，我们得知对於我们所研究材料的超导转变温度和费米面上的态密度无关。

Functional deficits of the supraspinous muscle in patients with early-stage impingement syndrome were not apparent during muscle relaxation.

然而，对于早期的肩峰撞击症患者来说，在肌肉放松时外展肌的功能不全表现得并不明显。

Work is contrary to rest. If you work hard, you will be tensional, tired and exhausted, then you can go into quiet valley of rest and enjoy deep relaxation.

工作与休息是相对的，如果你努力工作，你会变得紧张、劳累、精疲力尽，但是此后你进入休息的幽谷，进入深探的放松。

The regulation of DNA relaxation by Topo I is essential for DNA replication, transcription, and recombination events.

用来调节DNA 松懈的第一型DNA拓扑异构酶对於DNA的复制、转录和重组是不可或缺的一角。

The element Sb exists in many forms in the film: transpositional atoms and compounds such as Sb2O3, Zn7Sb2O14 etc. ZnO crysal grains grow in mixing directions. The lattice relaxation and content of second phases increase when more Sb is doped. The UVA absorption of doped ZnO thin film obviously increases. The ultraviolet absorption peak narrows, the absorption intensity increases, the absorption margin becomes steep and moves to shorter wavelength about 5 nm, and the visible absorption increases in some sort.

薄膜中Sb以多种形态存在：替位原子和化合物(Sb2O3、Zn7Sb2O14)等，ZnO呈混晶方式生长；随着Sb含量的增加，其引起的晶格畸变和次晶相的含量逐渐增加；掺杂薄膜在远紫外波段的吸收显著增强，UV吸收峰变窄，强度增大，吸收边变得陡峭且向短波方向移动达5nm，在Vis波段的吸收有所增强。

Finally, the Knight strung a line between two of the monoliths and tied the horses up there.

最后，骑士们在两颗巨石之间拉了一条绳子，将他们的座骑绑在上面。
