Take DMSO swollen treatment and DEA-SO2-DMSO decrystallization treatment for example, the X-ray diffraction and the Tobolsky's intermittent stress relaxation of treated woods were determined during soaking in water, analyzed the effects of water on crystal degree and inter-cohesion of treated woods. According to these continuous relaxation curves measured in water with different temperatures, various thermodynamic quantities were obtained by using Eyring absolute rate theory, and reviewed the chemical reactions in wood which occur in different relaxation process. For the first time quantify these crosslinkings formed in the process of tensional relaxation by using the SMCIR intermittent stress relaxation way, and defined the cross-linking reaction types. In order to find out the contribute of drying to the fixation of deformation of chemically treated wood, stress relaxation of oven-dry untreated and treated wood was measured during the process of temperature elevation and descend, then analyzed the effect of temperature change on relaxation mechanism of treated oven-dry wood. According to continuous relaxation curves of oven-dry treated wood under various constant temperature, calculated the thermodynamics of relaxation process and discussed the mechanism of molecule change in wood, at the same time, also quantified these cross-linkings produced in wood by intermittent method and on the basis of which the model of molecular change during relaxation process of chemically treated was constructed.

In this case, the solidification of the liquid phase formed at the hipping temperature led to the formation of crystalline intergranular phases at all temperatures: however, the chemical compositions of the intergranular phases formed in the specimens with and without carbon additions were different, since for high carbon contents the resulting intergranular phase was observed to be richer in Yttrium(85% at Y/15% at Si).

在这种情况下，加压温度下液态产物的凝固在所有温度范围下都将生成间粒晶体：但是，是否添加了碳则将会使产物晶体的化学成分发生不同，因为在高碳含量下，产物晶体会更富含钇(85%Y比15%Si)另一方面，我们必须强调的时，如果Al2O3作为第三方物质加入反应混合物粉末中，那么产物晶体的结晶度将被破坏。
