SCIAA教学法--基于"学生本位课程"的英语精读教学法

“学生本位课程”是以人本主义心理学和建构主义课程观为基础的一种新型课程。这种课程确立了学生在教学中的主体地位以及教师的主导作用，强调在教学中充分利用学生原有知识和经验。SCIAA教学法是笔者将“学生本位课程”应用于教学实践而形成的一种新的英语精读教学方法。     

下一代互联网中的智能QoS组播路由算法

设计了一种下一代互联网中的智能QoS组播路由算法,给定一个QoS组播请求和柔性QoS需求,包括带宽需求、组播端到端延迟区间,延迟抖动区间和出错率区间,寻找一棵QoS组播路由树.提出一种基于演化算法和单纯形算法的混合算法来构造满足上述需求且费用近优QoS柔性组播路由树,兼顾网络负载均衡.仿真结果表明,该算法是可行和有效的,明显优于基于传统遗传算法的QoS组播路由算法.

Development of the CAS-IBB single-particle microbeam for localized irradiation of living cells

A single-particle microbeam facility has been constructed at the Key Laboratory of Ion Beam Bioengineering (LIBB), Chinese Academy of Sciences (CAS). The system was designed to deliver a defined numbers of hydrogen ions, produced by a van de Graaff accelerator, in an energy range of 2.0-3.0 MeV, into an area smaller than that of the nucleus of an individual living cell. The beam is collimated by a borosilicate glass capillary that forms the beam-line exit. An integrated computer program recognizes the cells and locates them one by one over the microbeam exit for irradiation. We present technical details of the CAS-LIBB microbeam facility, particularly on the collimator, hardware, control program, as well as cell irradiation protocols available. Various factors contributing to the targeting and positioning precision are discussed along with accuracy measurement results.     

On the Strong Law of Large Numbers for Non-Independent B-Valued Random Variables

This paper investigates some conditions which imply the strong laws of large numbers for Banach space valued random variable sequences. Some generalizations of the Marcinkiewicz- Zygmund theorem and the HoffmannJφrgensen and Pisier theorem are obtained.     

Measurement of Magnetization Curve and Magnetic Relaxation for 2H-NbSe2 Crystals

The characteristics of electronic transport properties: behaviors of magnetization curve and magnetic relaxation of a typical normal superconductor 2H-NbSe2 are investigated. The results show that Tc and △Tc of the samples are 7. 2,0. 18 K, indicating that superconducting energy gap at zero temperature is 1. 1 meV. No fish tail shape is found in the magnetization curves at several temperatures. The relationship between remnant magnetic moment and time reveals that the magnetic flux creep of the sample agrees with the Kim-Anderson thermal activation model with the relaxation rate S=0.000 36 at T=6 K.
