A 150-min short procedure for the determination of homocystine content was developed on the basis of the physioiogical properties of homocystine and the analytical method of physiological body fluid (Hitachi Model 835-50 Amino Acid Analyzer).
根据日立835—50型氨基酸自动分析仪生理体液分析法，以及同型胱氨酸的生理特性，建立测定同型胱氨酸的150min短程序法。
XRD results show that all ceramic samples are perovskite and the morphotropic phase boundary(MPB)is located in x=0.
5TiO3系压电陶瓷,XRD分析表明所得陶瓷样品为纯的钙钛矿结构,其准同型相界在x=0。
