Abstract
This is the result of measuring the Aqeous Vapor Pressure of saturated Salt Solution by using the aparatus to measure the vapor pressure of solution, which is concidered by Prof., K. SHIBA, as shown in Fig. 1 and 2. In these several years we had studied about the vapor transfer through some building materials. This paper is one of the important specimen to measure exactly the aqeous vapor permeabilities in laboratory. The results are shown in Table 4, comparing the results by other authorities.
