Taking water-solubility preservative(ACQ-B) as the agentia, and the liquid medicine concentration (LMC), the forcing time, the liquid medicine temperature(LMT) and the pressure as the test factors, the permo-treatment was processed to the circle bamboo, and the technical conditions of the treatment were compared. The results showed that each factor and the levels in the same factor had all larger differences to the weight increase rate(WGR) of bamboo, and WGR of the specimens in the same level had also larger difference. Through variance, range and trend analysis, the technical condition for a...
