f—M—余正则序列和f—余模

在对模的正则序列、余正则序列及f-正则序列性质学习与研究的基础上，定义了拟局部环（A,Ψ）（Ψ为A的唯一极大理想）上Artin模M的f-余正则序列并给出了一些简单性质，由此定义了一类模－f-余模，并将f-余正则序列用于一类特殊的广义分式模，得到了一个正合性原理。

“多元智能理论”在背越式跳高教学中的实验研究

在我国,体育院校的背越式跳高教学是田径普修课的主要内容之一,对于背越式跳高的教学方法研究很多,而运用多元智能理论于背越式跳高教学的却尚未见到,为此,本文正是把多元智能理论应用到田径普修课背越式跳高教学的实践当中,通过教学实验证实：背越式跳高教学中应用＂多元智能理论＂,能够改变传统教学中的很多不足,能有效提高教学质量.     

k分Cantor集C_k上p方可积函数空间L~P(C_k,μ)的可分性

文献[1]已知三分Cantor集C上p方可积函数空间LP(C,μ)(1≤p∞)是可分的,将此结论推广到k分Cantor集Ck(k为1的奇数)上,证明了k分Cantor集Ck上p方可积函数空间LP(Ck,μ)(1≤p∞)也是可分的.     

SER analysis and power allocation for hybrid cooperative transmission system

The symbol-error-rate(SER) and power allocation for hybrid cooperative(HC) transmission system are investigated.Closed-form SER expression is derived by using the moment generating function(MGF)-based approach.However,the resultant SER contains an MGF of the harmonic mean of two independent random variables(RVs),which is not tractable in SER analysis.We present a simple MGF expression of the harmonic mean of two independent RVs which avoids the hypergeometric functions used commonly in previous studies.Using the simple MGF,closed-form SER for HC system with M-ary phase shift keying(M-PSK) signals is provided.Further,an approximation as well as an upper bound of the SER is presented.It is shown that the SER approximation is asymptotically tight.Based on the tight SER approximation,the power allocation of the HC system is investigated.It is shown that the optimal power allocation does not depend on the fading parameters of the source-destination(SD) channel and it only depends on the source-relay(SR) and relay-destination(RD) channels.Moreover,the performance gain of the power allocation depends on the ratio of the channel quality between RD and SR.With the increase of this ratio,more performance gain can be acquired.
