查询词典 retain

The results show that the sample is well dispersed particles with high purity and an average size of about 1 μm. Favorable substances of Ca2 and Sn appear during the cycling of zinc electrode containing CaSn6, Ca2 has continues to react with ZnO to produce calcium zincate, which can highly reduce the dissolvability of anode active materials and greatly improve the cycling performance of zinc electrode. The simulated Ni/Zn battery using CaSn6 and ZnO as the active material of zinc electrode has a high discharge plateau and an excellent cycling ability, and it can retain about 72.6% of initial discharge capacity after 50 charge-discharge cycles.

研究结果表明：通过共沉淀方法合成的CaSn6粒度分布均匀，平均粒径在1 μm左右，并且具有较高的纯度；添加CaSn6的锌负极在循环过程中游离出了Ca2和金属锡等有益物质，并进一步与ZnO反应生成锌酸钙，降低了锌负极活性物质在电解液中的溶解性，从而显著提高了锌电极的循环性能；以CaSn6与ZnO的混合物为负极活性物质的模拟锌镍电池具有较高的放电平台和优良的循环性能，经过50次循环后，电池放电容量保持为起始容量的72.6%。

His abilit y to endure such hard conditions and retain his sanity was little short of a mir acle.

First, the temptation to retire once Social Security benefits can be claimed, at the age of 62, seems irresistible for the majority of workers, even though the payments are actuarially reduced. Second, employers are reluctant to retain or hire older people, mainly because they find it hard to lower their wages if their productivity slips.

原因有二：一，工人到了62岁即可退休，一退休，即可领取社会保障金，多数人都难以抵挡这一诱惑（尽管据保险统计数据，支付给他们的保障金数额实际有所减少）；二，雇主不愿保留或再雇佣年纪较大的工人，主要原因是，这些雇主发现，即使这些人的生产力大不如前了，也很难把他们的工资降下来。

Based on the classical Ekman theory, a series of intermediate Ekman boundary layer models, which retain the nonlinear advective process while discard embellishments, have been developed with the intention to understand the complex nonlinear features of the Ekman boundary layer and its interaction with the free atmosphere. In this paper, the recent advances in the intermediate boundary-layer theoretical models are reviewed.

摘要大气边界层及其与自由大气之间的相互作用具有明显的非线性特征，而这些特征是经典Ekman理论所不能描述的，因此，发展中等复杂程度（介于完全模式与经典Ekman模型之间）的大气边界层动力学模式，简称中间模式，对人们从理论上认识大气边界层动力学过程的非线性特征具有重要意义。

Chibeitao, scissors, can reduce root pedicle of the particles to retain integrity, and the dilution of salt water immersion, to elimination of the effect of residual also clean the surface layer of tunica albuginea can squeeze some toothpaste, the grape placed in the palm of your hand, light Knead increases, the water, can be completely crystal clear, eating up more peace of mind!

吃葡萄时，先拿剪刀减到根蒂部分，使其保留完整颗粒，并浸泡稀释过的盐水，达到消菌的效果，冲洗乾净表面还残留一层白膜，可挤些牙膏，把葡萄置于手掌间，轻加搓揉，过清水之后，便能完全晶莹剔透，吃起来更安心！

As a functionally and phenotypically distictive T cell subpopulation,CD4+CD25+ regulatory T cells are anergic and retain their ability to suppress antigen-driven response of CD4+CD25- cells in a contact-dependent manner or through a way of secreting immunosuppressive cytokines such as IL-10 and TGF-β.

CD4+CD25+调节性T细胞是一群表型和功能特异的T细胞亚群，具有免疫无能和免疫抑制两大特性，通过细胞直接接触或分泌抑制性细胞因子发挥对CD4+CD25-T细胞的抑制作用。

NOTWITHSTANDING THE PROVISIONS OF UCP500,IF ISSUING BANK GIVE NOTICE OF REFUSAL OF DOCUMENTS PRESENTED UNDER THIS CREDIT,ISSUING BANK SHALL HOWEVER RETAIN THE RIGHT TO ACCEPT A WAIVER OF DISCREPANCIES FROM THE APPLIANT AND SUBJECT TO SUCH WAIVER BEING ACCEPTABLE TO ISSUING BANK,TO RELEASE THE DOCUMENTS AGAINST THAT WAIVER INSTRUCTIONS TO THE CONTRARY HAVE BEEN RECEIVED BY ISSUEING BANK FROM THE PRESENTER BEFORE THE RELEASE OF THE DOCUMENTS .

尽管UCP500规定，如果开证行通知拒绝接受有关此信用证的交单，但是开证行须要为开证申请人保留接受信用证不符点的权利，开证行接受开证申请人接受此不符点；凭接受不符点的保函，开证行将受益人提交的单证放给开证申请人。开证行不就此放单行为对受益人负责。

The director of the Ashmolean Museum in Oxford once mused that the best strategy for the museum might be to sell part of its collection to provide funds to look after the rest; he doubted whether he would retain his position if he carried out such a strategy.

牛津大学的AjlMloleM博物馆的馆长曾经思考过这一问题：博物馆最好的策略也许是卖掉部分收藏从而获得管理剩下馆藏的资金。他怀疑一巳他实施了这个计划，他是合还能留任。
