Male patient was prevalent in aphasic groups, but mean age of both gender groups was no difference. The possible explanations may be adduced for our findings; one is related to the cerebrovascular changes of aging- The decrease of cerebral circulation is prominant and disseminated in increasing age. There may be changes in the cerebral blood flow associated with aging, predisposing different brain areas to stroke. The second is possible that changes in cognition, deterioration of memroy and comprehension disturbance may predispose the perception dysfunction of language or advanced language dysfunction like global aphasia in aging group.

在各类失语症中，Broca矢语症的平均年龄为54岁，明显的比全失性失语症的平均年龄64.6岁和经皮质层感觉性失语症的平均年龄61岁都小，显示Broca失语症较易发生於年龄较轻者，而年龄较大者发生全失性失语症和经皮层感觉性失语症的机会较多，至於男女两组失语症病人在平均年龄上并无明显差异，但失语症的发生率男性比女性多，且性别上的差异也与失语症的型式有明显相关。

The main contributions in this area are summarized as follows,? The closed-form formula and its asymptotic form of system outageprobability are derived, through which it is shown that the outage probability decreased by a factor ofγ~(hereγdenotes the average SNR);? The closed-form formula of outage capacity is derived, through which weshow that 1 outage capacity increases with the increases of mean value of sytem SNR, and decreases with the increase of the variance of system average SNR; 2 in order to obtain higher outage capacity, the number of transmit antenna should be no more than that of receive antennas.?

特别的，针对多用户发送天线选择／最大比合并系统，主要贡献总结如下：·理论推导出中断概率的闭式解及其近似解，通过该近似解，可以得到中断概率以γ~的形式减少(这里γ是平均信噪比SNR)·推导出平均中断容量的闭式表达式，研究表明：1中断容量随着有效平均SNR的均值的增加而增加，随着有效平均SNR的方差的增大而减小；2为了获得更高的中断容量，发送天线的数目应当不大于接收天线的数目。
