所有海員起居艙室的甲板應為認可的材料和構造，其表面應能防滑、防潮並易於保持清潔。 -
The walls and pillars shall have white or light - colored surface ; the part within one meter above the ground shall bepaved with non - absorptive, impervious and easy - to - clean material with surface which shall be smooth and maintained clean and free of cracks
四墻壁與支柱表面應為白色或淺色，離地面至少一公尺以內之部分應使用非吸收性、不透水、易清洗之材料鋪設，其表面應平滑無裂縫並經常保持清潔。 -
Impervious wall is thin and deep, so it cannot satisfy the hypothesis of half space. the surface wave theory of impervious wall is analyzed and proves that surface wave speed in impermeable wall is nearly equal with that in plane - strain problem, so the transverse w ave speed getting by rayleigh surface wave exploration technique can satisfy the precision desire of engineering
我們對面波在防滲墻中傳播原理進行了分析，證明防滲墻中的面波波速與半空間理論中面波波速差別很小，因此，用瞬態面波檢測技術來獲得剪切波速可以滿足工程精度的要求。 -
High - density seismic image can find problems in impervious wall quickly, so we use it to find out the place that may has problem, then use rayleigh surface wave exploration technique to give more detecting. in this way, the non - destructive detecting speed is increased
為提高檢測速度，我們利用高密度震動映像技術快速、直觀的特點，首先對防滲墻整體的施工質量進行檢測，快速發現可能存在問題的地段，然後再用瞬態面波技術作進一步的檢測。
