Based on calculating the first-order corrections to the energy from relativistic and mass-polarization effects, we estimate the higher-order relativistic contribution and QED correction to the energy under a hydrogenic approximation. The transition energies, wavelengths and oscillator strengths for the 1s23s-1s2np transitions of this ion are calculated.

With innovative QACAS technologies,we resolve the crucial schedule problems for PCISA such as "when,what,how many,how" problems for servers. QACAS guarantee fast response,scalability,availability,manageability for PCISA system. Furthermore,QACAS improve the efficiency of resource utilization,resolve the problem of unexpectable and incontrollable QoS,providing cluster level support for the deployment of flexible differentiated service strategies.

QACAS通过创造性的集群QoS控制技术、集群容量规划与控制技术，解决了PCISA系统中服务器何时取、取什么、取多少、如何取等关键调度问题，保证PCISA系统满足快速响应性、高可伸缩性、高可用性、易管理性等集群系统基本性能要求，而且提高了系统资源的有效利用率，解决了服务质量无法预期和控制的问题，为网络应用实施灵活的区分服务策略提供了集群一级的支持。

Methods selective and limited minimally invasive debridement under arthroscope was applied to 54 patients with osteoarthritis of knee joint; hyperplasia of inflammatory synovial membrane and abrasion of anterior cruciate ligament were chipped or vaporized with radiofrequency, the corpus liberum were taken out, cartilage was scoured into certain shape; excision or partial excision were performed to hyperplastic intercondyloid spine, osteophyma and menisci; intercondyloid fossa was formed.results 45 cases were followed up for an average of 18 months (from 6 months to 24 months); the clinical symptoms of most cases released obviously and the joint function improved.conclusions minimally invasive debridement under arthroscope can effectively release oa symptoms, improve joint function and raise the quality of life.
