中国认可实验室4255个居世界首位

不久前，国际认可论坛（IAF）和国际实验室认可合作组织（ILAC）联合大会在沪召开。ILAC和IAF是国际认证认可界的权威组织。长期以来，ILAC和IAF积极倡导在全球范围内建立一致、有效的合格评定认可体系，形成国际多边互认机制，促进认可的合格评定结果获得广泛的国际承认，从而达到减少贸易技术壁垒、促进国际经济贸易发展的目的。     

Twenty-five years of excellence: a retrospective glance of Acta Mechanica Sinica

The first version of Acta Mechanica Sinica （AMS） was launched in June 1985 in Beijing, aimed at delivering the cutting-on-edge progress and achievement in Mechanics in China to the world, allowing world-round colleagues to access the work of Chinese mechanician, and supplying an international forum in the field. Its appearance was a result of 5-year preparation after the consensus agreement by the Acta Mechanica Sinica Editorial Board （3rd）, and was approved by the China Association for Science and Technology and supported by the Chinese Society of Theoretical and Applied Mechanics （CSTAM）.

Searching for Flavor-Changing Neutral-Current Signals via e＋e-（γγ） →tcht0 in Topcolor-Assisted Technicolor Model

In the context of the top-color-assisted technicolor （TC2） model, the flavor-changing neutral-current （FCNC） interaction induced by the top-higgs （hOt） are predicted at tree level. We study the relevant processes of e＋e-（γγ）→tcht0 at the International Linear Collider （ILC）. It is found that these rare processes production rates can be enhanced significantly in the TC2 model. Especially for the process γγ→tcht0, the total cross section will reach a few fb in the reasonable parameter space. We also calculate the distributions of transverse momenta, pseudo-rapid and invariant mass of the top-higgs. In view of the main decay modes of top-higgs for mho 〈 2mr, we find that there will be several hundreds FCNC events produced at the ILC with annually integral luminosity of 500 fb-1. Due to the clean background, such FCNC signals can possibly be detected at the ILC.     

银行资本管理术

近年来，随着银行金融体制改革向纵深推进，金融监管逐步与国际接轨，中国银行业正面临着对资本约束的考验和风险文化的冲击。尽管目前多家银行虽然实行了经济资本管理，但是由于理解深度不够，操作不规范，存在一些不足之处。例如，
