10. a kind of application method of multi-opening multi-cavity quick-change type timber Microwave Pretreatment device, it is characterised in that：Including following step
Suddenly：S1：Make test specimen：Timber processing squarely and cylinder specimen by moisture content higher than 10%, the thickness of square lumber between
10-120mm, length and width is between 100-290mm, and the height of cylindrical timber is between 70-490mm, and diameter is between 10-
290mm；
S2：Test specimen drills with weighing：4-8 a diameter of 1mm of processing on square and cylinder specimen, depth 10-30mm's is pre-
Box out, weigh in the balance and take each timber test specimen initial mass and record；
S3：Microwave source and resonant tank module are installed：The microwave source and resonant tank module of selection are fixed on universal head
（1）On, by infra-red ray detection device（21）Installed in resonance cavity shell（3）On, connect microwave source（4）Power lead, follow
Ring water pipe, connects temperature detecting module（2）Temperature sensor line；
S4：Test specimen is installed：The timber test specimen of selection is placed in resonator（31）In, optical fiber is then passed through into metal cover（6）
On through hole（61）, optical fiber temperature probe is inserted into the preformed hole in timber test specimen, by the thermometric end of optical fiber
With universal head（1）Connection；
S5：Microwave Pretreatment：Start universal head（1）, make magnetron（41）, refrigerating module（42）, infra-red ray detection device
（21）The temperature change feelings of Microwave Pretreatment, observation timber surface of test piece and inside are carried out to timber test specimen with optical fiber operation
Condition, the temperature of wood internal is no more than 220 DEG C；
S6：Terminate：Close down universal head（1）, take out the timber test specimen after microwave treatment and it weighed and recorded.
