Those ions will perform stable oscillation nearby the beam orbit while their mass is larger than a critical mass. The accumulation of trapped ions nearby the beam orbit, interacting with beam, can cause the tune shift of beam, blowup of beam emittance, increase of local vacuum pressure, and can even lead to the occurrence of beam instability.

这些被俘获的离子在束流轨道附近的积累并和束流的相互作用，会引起束流振荡频率的漂移和展宽、束流发射度的增加、局部真空度的恶化等各种负效应，有时甚至会导致束流不稳定的发生，从而影响储存环的正常工作，在这种情况下采用离子清洗方法将离子清洗掉对保证储存环的长期、稳定的运行是必要的。

The influence of parameters such as high order mode shapes,horizontal and vertical power spectrum density,basic wind pressure, span and weight of the roof,damping ratio,terrain categories and support restraints, which are usually critical to the wind-induced vibration responses,are discussed.

尽管这些大跨屋盖结构的形式不尽相同，但它们都具有一些共同特点，即质量轻、柔度大、固有频率低、阻尼小等特点，它们都属于风敏感结构，因而风荷载就成为设计这些屋盖结构的主要控制荷载之一。

Furthermore,the influence of parameters such as the horizontal power spectrum density, basic wind pressure,span and weight of the roof,damping ratio,terrain categories and support restraints,which are usually critical to the wind vibration factor,are also discussed.

本文基于随机振动理论利用有限元程序ANSYS对大跨度实腹式钢梁在频域内进行了风振分析，讨论了高阶振型、脉动风速谱、基本风压、屋盖重量、地貌种别、阻尼比和支座约束等相关参数对屋盖结构风振响应和风振系数的影响。

深入研究了水压场建模的理论和方法，包括回转体模型和浅水亚临界模型，用实测数据对回转体模型和浅水亚临界模型进行验模，为不同条件下选择水压场模型提供了一定的理论依据，并在实测数据的基础上对模型进行了修正。

Pressure sore prevention and treatment of critical care is more important overall.

预防和治疗压疮至关重要，整体护理更重要。

Since 2003 year, in two major ways, funds and lands have the governments macro-controlled the whole industry in order to keep the estate industries healthy and sustainable growth and evade the risk. Since funds and lands are the understructure upon which the estate companies have developed, the government control concerning them have made the whole industry faced a critical financing hardship. Consequently, many companies which used to extremely depend on bank credits are confronting the financial pressure. Many middle and small enterprises are even facing the problem of maintenance. Accordingly, under the background of the present macro-control, the debates and research over the diversity of estate companies' financing mode are abundant in its realistic meaning.

为了保持房地产行业健康、可持续发展，规避房地产金融风险，我国政府自2003年以来主要从资金和土地两个方面对房地产行业进行了宏观调控，由于资金和土地是房地产开发企业赖以生存的基础，多管齐下的调控措施打破了房地产开发企业原有的开发模式和融资模式，使得房地产开发企业普遍遭遇融资困境，过去以银行贷款为主要融资方式的房地产开发企业普遍面临资金压力，许多中小型房地产开发企业甚至面临生存问题，因此，在当前宏观调控背景下，探讨中小型房地产开发企业融资模式多元化问题具有很强的现实意义。
