本文的目的是确认脉冲压力波对半开放容器中液体渗透到木材中的影响。木块样品在装有水作为液体的半开口容器中受到脉冲压力波的照射。为了进行比较，也在密闭容器中进行照射。压力波照射促进了水渗透到样品中。封闭容器和半开放容器之间的渗透程度几乎没有差异。从测得的液压推测，照射在密闭容器中的样品上的压力波能量高于半开放容器中的样品。还推测在半开放容器中促进了空化的产生。这表明空化以及压力波本身影响液体渗透到木材中。半开放容器中辐照样品的压缩变形略小于密闭容器中辐照的样品。这表明半开口容器中的脉冲压力波照射促进了液体渗透到木材中，且压缩变形较小。
The purpose of this paper was to confirm the influence of pulsive pressure waves on the liquid penetration into wood in the semi-opened container. Wood block sample was irradiated by the pulsive pressure waves in the semi-opened container filled with water used as a liquid. The irradiation was also performed in the closed container for the comparison. The water penetration into the sample was promoted by the pressure-wave irradiation. There was little difference in the degree of the penetration between the closed and the semi-opened containers. It was presumed from the measured hydraulic pressure that the pressure-wave energy irradiated on the sample in the closed container was higher than that in the semi-opened container. It was also presumed that the cavitation generation was promoted in the semi-opened container. This indicates that the cavitation as well as the pressure waves themselves affected the liquid penetration into wood. The compressive deformation of the sample irradiated in the semi-opened container was slightly smaller than that in the closed container. This indicates that the pulsive pressure-wave irradiation in the semi-opened container promoted the liquid penetration into wood with less compressive deformation.
