体育消费的学理脉络、统计内容及其实施策略

采用文献资料法，依次从学理脉络、统计内容及其实施策略展开关于体育消费以及体育消费统计的讨论。认为：从学理上看，体育消费作为一个复杂概念，既牵涉宏观经济社会发展，也与文化意识形态紧密联系；而作为准确把握体育市场、把脉体育发展情况的基础性工作之一，体育消费统计则应该避免将体育消费概念泛化。应以体育政策为导向，面向人民的美好生活需要，对接国民经济统计制度，考虑建构以“体育教育与培训、体育文化与娱乐、体育保健与康复、体育传媒与信息、体育衣着耐用品、其他体育用品与服务、个人间接体育消费”为核心指标的统计框架，并通过长效工作方案的设计使体育消费统计工作制度化，通过统计调查制度的建构使体育消费统计执行有效化，通过统计数据的测算推算使体育消费统计结果精准化。     

信息化教学在网络综合布线课程中的实践

随着信息技术的迅速发展,作为一种新的教学形态,信息化教学改变了传统教学的模式。该文阐述在信息化教学环境中如何结合信息化教学模式创新,解决传统网络综合布线课堂教学存在的问题,从而提高课堂教学效率。     

^13C的一个可能的类晕的中子1p态

假设^13C是单粒子的2p态的结构，用Glauber多重散射理论研究了入射能量为1GeV的质子在^13C上的弹性散射，得到了与实验符合得很好的理论结果。这说明^13C可能存在着一个类晕的中子皮。

Nuclear Shadowing Effect on the K Factor in Au—Au Collisions

We investigate the nuclear shadowing effect on the K factor in the Drell-Yan process by introducing a Shadowing factor into the corresponding quantum chromodynamical αs order corrections.K factors for Au-Au collisions are calculated at the centre-of-mass system energies √s=60,130 and 200 GeV while the nuclear shadowing factor is taken into account.The numerical results indicate that the nuclear shadowing factor obviously raises the K value in the small x region,and for the same nucleon the K valus becomes smaller as the energy increases.The nuclear shadowing effect could be one reason for creating the non-constancy of the K factor.     

Realization of the Fredkin Gate by Three transition Pulses in a Nuclear Magnetic Resonance Quantum Information Processor

We have experimentally realized the Fredkin gate with only three transition pulses in a solution of alanine.It appears that no experimental realization of the Fredkin gate with fewer pulses has been reported yet.In addition,the simple structure of our scheme makes it easy to implement in experiments.     

New Explicit Solitary Wave Solutions and Periodic Wave Solutions for the Generalized Coupled Hirota－Satsuma KdV system

In this paper,we study the generalized coupled Hirota-Satsuma KdV system by using the new generalized transformation in homogeneous balance method.As a result,many explicit exact solutions,which contain new solitary wave solutions,periodic wave solutions,and the combined formal solitary wave solutions,and periodic wave solutions ,are obtained.
