| 内容記述 | Oven dryed saw dust of HINOKI (Chamaecyparis obtuse ENDLICHER) and that of KEYAKI (Zelkowa serrata MAKINO) are analysed at intervals of 4days. The temperature of heating is 130℃, during 12days. From the results of the analyses (Table 1 and Fig. 1), the rate of increase or decrease of content of each constituent is calculated (Table 2), and compared with the data on the corresponding old timbers (Fig. 2). The conclusions obtained from this comparison are as follows : 1) The difference between the rate of decomposition of cellulose in KEYAKI and the rate in HINOKI, which is evident in the old timbers, becomes less significant under this condition (Fig. 2). 2) In this heat treatment, the amount of generated soluble constituents, accompanied with the decomposition of the standard amount of cellulose, is less than that amount found in the old timbers (Table 3). And with KEYAKI the amount is less than with HINOKI (Fig. 2). 3) The rate of decomposition of cellulose under this condition is about (10)^4∿(10)^5 times as much as the rate in the old timbers (Table 4). | |||||
