The conditions to measure accurately and the principles to select parameters of the multi— probes EST method are proposed, and the theoretical research, computer imitation and the experiment on a machine tool prove that these principles and suggestion are necessary and effective. The influence of the initial value errors of the probes, the installation error of the probes system, and the remaining error caused by the radical error motion are analyzed quantitively on the measurement accuracy of the multi—probes EST method. The influence of the error caused by the probe's axes which is not in a plane and the perpendicularity error of the plane which the probe's axes is in to the stational axis are discussed on the measurement results.

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。
