传统进行树干解析时，在判读年轮、量测年轮宽度和计算上容易产生较大的误差或错误。从日本引进的树干解析装置对圆盘年轮的查定和宽度量测具有相当高的精度，利用微机与其连接，可充分发挥两者的优势。但引进的程序在使用上存在一些问题，经笔者修改并在原有基础上重新编程后，对部分解析本进行实测和数据计算，结果表明，该系统具有测定和计算精度高、操作简便、速度快的特点，可以完成从测定到结果输出工作量的95％．
Traditional trunk analysis, interpretation of annual rings, measuring the width and calculation of annual rings prone to greater error or error. The trunking analysis device imported from Japan has a very high precision for the identification and width measurement of the disc rings, and the advantage of both can be brought into full play by connecting with the microcomputer. However, the introduction of the program in the use of some problems, after the author to modify and re-program based on the original, the part of the analysis of the actual measurement and data calculation, the results show that the system has the measurement and calculation of high precision, easy to operate, fast The characteristics of the output can be completed from the measurement results to 95% of the workload.
