Abstract
An auxiliary measuring device and a measuring method used for analysis of tree annual rings. The invention relates to the auxiliary measuring device and the measuring method used for analysis of the tree annual rings and aims to solve a problem that a sample core is liable to break or deform so that measurement accuracy is seriously influenced since an auxiliary measuring device for fixing and protecting a tree annual ring sample core is lacked during analysis of the tree annual rings in the prior art, a light-leakage phenomenon is very liable to occur during a scanning process so that a scanned image photographic effect is seriously influenced, and an image effect and a definition are difficult to be ensured so that a following measurement result is directly influenced and work efficiency is low. The measuring device includes an accommodating box and an accommodating box cover plate. A plurality of bar-shaped grooves are formed in the upper end surface of the accommodating box in parallel. The accommodating box cover plate is buckled on the accommodating box. The device and the method are used for measurement of the tree annual rings.
