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。

More than 50 GaAs/GaAlAs High Power Single Quantum Well Semiconductor Lasers are aged. The threshold current decreases during the early aging (first 520 h) and the largest decrease is 57 mA. From the aging result of more than 1000 h at constant current, we find that output power increases during the early aging , and then decay slowly according to exponent law.

通过对50余只808nm的GaAs/GaAlAs高功率单量子阱远结半导体激光器的老化实验观测，在老化初期（前520h），阈值电流随老化时间的延长而下降，下降幅度高达57mA，从1000h多的恒流电老化结果可以看出，器件的输出光功率在老化初期有所上升，随后，表现出按指数规律缓慢下降的行为。

Organism aging comes from cell aging, so study on diploid cell line is helpful to research the mechanism of aging.

机体的衰老来源于细胞的衰老，对二倍体细胞的研究有助于衰老机理的探讨。

So far, the synthesis of facial aging image usually based on a single mode, with no consideration of different aging trajactories for various persons. Although foreign researchers had built aging database with considerable bulk, the facial images are mainly Caucasians, which are not appliable to our yellow race. In the meanwhile, methods based on 3D face models are too complicate and expensive to generalize to real-life applications.

以往对人脸图像的衰老合成通常只是基于单一人脸的信息；或者按单一模式来处理所有人的衰老，并没有考虑不同种类人有着不同的个性化变老途径；虽然国外的学者建立了较大容量的人脸衰老数据库，但它只适合于西方人，并不适用于亚洲人种，且对从青年至老年阶段的衰老究尚不够深入；而基于三维模型的衰老模拟技术目前还存在数据获取及操作不便的缺点，限制了其应用推广。
