查询词典 aging analysis

Pristine Li-Al LDHs are synthesized by hydrothermal process in different reaction conditions by varying the aging time for 1 and 24 hours. Both the Li-Al layered double hydroxides (abbreviated as Li-Al LDH1 and Li-Al LDH24 for aging time 1 hour and 24 hours, respectively) were modified by using sulphanilic acid sodium salt hydrate, modified agent to form modified Li-Al LDH1-SAS and Li-Al LDH24-SAS. The morphology of the pristine layered double hydroxides are investigated by using wide angle X-rays diffraction, scanning electron microscopy and particle size analyzer which indicates that the crystallinity and aspect ratio is increased with increasing the aging time from 1 hour to 24 hours. The particle size of Li-Al LDH24 and Li-Al LDH1 are found to be ~1000 nm and ~250 nm, respectively. Both the pristine and modified LDHs are characterized by XRD, FTIR spectra and thermogravimetric analysis.

本研究目的在於改变长晶时间的长短，合成出同径大小的Li-Al LDHs，再经由改质剂sulphanilic acid sodium salt hydrate将Li-Al LDHs无机层材表面有机官能化制备出改质型Li-Al LDHs-SAS，於是进一步藉由扫描式电子显微镜、射径仪和穿透式电子显微镜等仪器分别观察LDHs改质前和改质后其主层结构型态上的变化；从中可以发现Li-Al LDHs随著长晶时间的增加其径有随之增大的趋势，但经有机化改质后其径会由於改质环境的影响明显低许多，针对此现象本实验将未改质和改质后之Li-Al人工无机层材制备成复材进一步探讨其在热性质和难燃特性上的为表现。

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.
