| Abstract: | Near infrared spectroscopy has the advantage of fast,clean,low cost and accuracy. Compared to other nondestructive testing methods,it is widely used in agriculture,medicine,chemicals,paper and other fields. Many domestic and foreign researchers made a lot of exploration in wood analysis and detection. This paper describes the importance of timber properties analysis,basic principles and characteristics of near- infrared spectroscopy. Forestry science and technology workers made numerous contributions to the progress and achievements in physical and mechanical properties of detection about MOR,MOE,density and compressive strength on different species,such as radiate pine,blue eucalyptus,loblolly pine,and eucalyptus pellita. |
