Objective To evaluate clinical effect of expandable intramedullary nail in unreamed treatment of tibia fracture.
目的评价可膨胀交锁髓内钉不扩髓治疗胫骨近端骨折的临床疗效。
From the perspective of international nuclear security, the former Soviet Union had a large nuclear arsenal, therefore, the collapse of it inevitably affects the international nuclear non-proliferation regime heavily and brings lots of practical problems to Russia—the legal successor of Soviet Union, in the field of nuclear non-prolife.
从国际核安全的角度讲,由于前苏联拥有庞大的核武库,所以苏联的解体必将对国际核不扩散形势带来负面影响,这也使其合法继承者俄罗斯在核不扩散领域不得不面对诸多急需解决的现实问题。
The Treaty On the Non-Proliferation of Nuclear Weapons is the core of nuclear non-proliferation system.
《不扩散核武器条约》是核不扩散机制的核心,但是它决不仅涉及不扩散,而是涉及了核裁军、无核区、安全保证、核禁试、核出口控制、核安全以及反核恐怖等多个相关问题。
Nonproliferation means no proliferation of WMD and their deliveryvehicles of WMD.
不扩散是指防止大规模杀伤性武器(简称WMD)及其运载工具的扩散。
Research and Optimize on Pixel Unexpanded and Threshold Visual Cryptography Scheme;
像素不扩展及门限视觉密码方案研究与优化
Based on characteristic that the human visual system averages over close pixels gray levels,through preprocessing of region segmentation and multi-line scan in mark-sharing process,a multi-line scan based pixel unexpanded MSM visual cryptography scheme has been proposed.
根据人眼的空间均衡特征,通过对图像进行区域分割预处理,采取多行扫描(Multi-lineScan)、标记分享(Mark-sharing)的方法,文章提出了基于多行扫描的像素不扩展视觉密码方案(以下称MSM-VCS)。
