JMFA-A Graphically Interactive Java Program That Fits Microfibril Angle X-ray Diffraction Data

摘要

Because much of our future timber resource is expected to come from short rotation plantations, we need to develop silvicultural practices that will iimprove the quality of the timber coming from these plantations. Short rotation plantations tend to produce timber with a higher percentage of juvenile wood, which has substantially lower mechanical property values than does mature wood. Measuring the microfilbril angle (MFA) of wood gives important clues about the characteristics of the wood and can be used as a silvicultural tool to improve the quality of a plantation. In this report, we discuss a graphically interactive Java computer program that permits a user to estimate MFA from X-ray diffraction profiles.
