To validate the above conclusion, a series of mixture tests were performed and different samples were made by mixing each of three kinds of nature silt and the nature clay with different mixture ratio. The liquid-plastic limits of all the samples, in which the clay particles content were between the nature silt and the nature clay, were attained using the combined test method. The results showed that the lowest clay particles content of the silt, when it was suitable with the combined test method, is 12% to 15% with little differences. If the point of 3～4mm depth of penetration of fall cone exist, and the loglog relationship between the depth of penetration of fall cone and the water content of all the points were clearly linear, it could be concluded that the clay particles content of the sample is over the lowest value when the combined test was suitable.

3其后为了进一步验证所得结论，针对三种粉土，分别与一种黏粒含量较大的天然黏土进行多种组合的配比试验，配比后的土样其黏粒含量均介于原粉土与原黏土之间，并对各种配比后土样进行联合测定法确定液、塑限的试验研究，得出各种土对联合测定法适用的最低黏粒含量限值因粒径组成不同、矿物组成不同等因素，存在微小差异，在12%到15%之间；当圆锥下沉深度在3～4mm之间的试验点存在，且与其他试验点之间能形成良好的双对数直线关系，即认为土中黏粒含量超过该土对联合测定法适用的最低限值，联合测定法适用。

During the four years study on the project, we develop a dynamical forecast model that describing the subtropical ridge surface. A new theory on the role of the land-sea thermal difference on the formation of the Subtropical High is advanced. It is concluded that in the summer subtropics over each continent and its adjacent ocean LO, SE, CO, and a double-dominant heating from west to east compose a LOSECOD heating quadruplet. The influence of the Eurasia continent on SH varies according to the seasonal variation. From the ideal numerical simulation it is shown the important role of the Eaiuan continent and the huge topography on the mechanism of formation and mantanence of the SH during the summer. It is verified by the numerical simulation that the extension of the subtropical continent into the tropics greatly enhances the " East Asian monsoon". Through the Rossby energy dissipation theory it is verified that the deep latent convective heating induces the onset of the South China Sea monsoon over the Bay of Bengal. The relationship and mechanism between the precipitaiton over the East Asia and the Subtropicla high is illustrated by the data. It is also found the close phase lock between the east-west shift of the SH and the disturbence of the east wind belt over the tropical troposphere. The interaction between the structure and activity feature of the SH and the Meiyu over the Yangtze-Huaihe river valley is revealed from the data. The numerical simulation verified the impact of the different SH pattern on the path of the typhoon.
