Since PGA is more highly degradable than PLA, PGA can be first hydrolyzed to glycolic acid in the PLA/ PGA conjugate fiber. 由于PGA比PLA更易降解,在PLA/PGA复合纤维中PGA能首先水解为乙醇酸。
The experiment of MOPA ( Master Oscillator Power Amplifier) laser system with an optical fiber as the phase conjugate mirror is reported. The laser beam from the unidirectional ring resonator was amplified and then coupled in a optical fiber to get the phase conjugate beam. 介绍了采用光纤作为位相共轭镜应用于MOPA(Master-Oscillator-Power-Amplifier)系统的初步实验,利用单向环形腔振荡器输出并经一级放大,将放大后输出激光耦合到光纤中获得了位相共轭激光输出。
A method of conjugate measuring network for on-line transmission performance monitoring of optical fiber digital communication is introduced here. 介绍了在线监测光纤数字通信线路传输性能的测试子网方法和测试结果。
In the forth chapter it present the idea of conjugate spinning to the defects of PLA, and studied the spinning process of conjugate fiber and tested the basic properties of conjugate fiber, it also studied and analyzed the degradable properties conjugate fiber. 第四章则针对聚乳酸纤维存在的缺点提出了复合纺丝的构想,并通过试验研究分析了复合纺丝工艺,并对复合纤维基本性能进行测试,研究分析了复合纤维的降解性能。
A new core-sheath conjugate fiber was obtained through PLLA and PGA conjugate spinning, and the tensile properties and micro-structure were discussed. 通过聚乳酸(PLLA)、聚乙醇酸(PGA)的复合纺丝,获得一种新的皮芯复合纤维,并对纤维拉伸特性和微观结构进行探讨。
