“…They observed that the upper limit of salinity that allows quick clay development in the Swedish-sensitive clays may be higher than the content found by Torrance (1974). They also found the Mg 2+ concentration to be less than 100 mg/l when the clay is quick, in agreement with previous findings by Talme et al (1966).…”

“…However, a low salt content does not necessarily imply that the clay is quick but only that a precondition for this exists. Torrance (1974) found that the salt content has to be reduced below 2 g/l (0.2%) before quick clay can be formed. However, quick clay with a salinity (NaCl concentration) of 5.6 g/l was found by Andersson-Sköld et al (2005).…”

“…The larger portion of univalent ions of the total content of ions in the pore water, the better conditions for a high sensitivity. Torrance (1974) found that the salt (NaCl) content had to be reduced below 2 g/l (0.2%) before quick clay could be formed.…”

Quick clay has been involved in most serious, large clay slides in Sweden, Norway, and Canada. This paper describes geotechnical and geophysical methods that can be used to locate and map the extent of quick clay formations. Surface resistivity measurements and four different sounding methods have been tested. The results have been compared with sensitivities determined using fall-cone tests. The investigation shows that there is a correlation between sensitivity and electrical resistivity, which can be used to discriminate between marine clays that have been leached sufficiently to possibly form quick clay and those for which the salt content remains sufficiently high to prevent this. Although the most reliable evaluation of the variation in sensitivity was obtained by the CPT with additional measurement of total penetration force, this investigation suggests that any sounding method that uses a constant rate of advance into the ground and in which the penetration force applied on the top of the rods is measured may be used for quick clay mapping.

“…(Guilford,1967) [8] Some scholar made the definition from the view of "progress" and suggested that creativity is a series of thinking progress. (Torrance, 1974) [14] The definition that is acknowledged by most scholars came from Amiable, named that "creativity is a certain combination of individual personality, cognitive and social environment." Creativity is the source and essence of entrepreneurship.…”

Abstract-In recent years, colleges have paid more attention to entrepreneurship education. The government in china emphasizes much on the entrepreneurship issues, puts forward many programs and policies of supporting college students' entrepreneurship, and encourages them to start their own business or entrepreneurial activities, but college students are faced with different challenges and risks in their real entrepreneurial activities all the time. At present, there are many researches on the entrepreneur intention of college students. In this research, based on the Theory of Planned Behavior (Ajzen, 1991)[2],we discusses the entrepreneurial behavior of female students in higher vocational colleges, mediating role of creativity and moderating Effect of entrepreneurial knowledge, which are analyzed from the view of gender. The female students in higher vocational colleges are taken as the target of investigation to discuss the relation between entrepreneur intention and entrepreneurial behavior.

“…At home and abroad there is a lot of literatures about the soil resistivity test and analysis, including indoor tests and field tests [1][2][3][4][5]. In this paper, three kinds of edible salt were selected for indoor experiments, and the correlation between sodium and other ions and the resistivity was explored.…”

The characteristics of the soil in the southeast coastal area of Zhejiang province is affected by the salt content of soil layer. In this paper, the resistivity of the solution of 3 kinds of edible salt mixed with pure water is studied. The test results show that the resistivity of the solution with the same ion concentration is independent of the water pressure, so the resistivity of the solution can be obtained through the mean value of different depth resistivity. There is a good correlation between the sodium ion content and the resistivity, and the total ion content is the same, but the correlation between the total ion concentration and the resistivity is better than the sodium ion, especially when the ion concentration of the mixed solution is less than 4 g/L. And the effect of the sodium ion on resistivity is more significant than other ions, but when the total ion concentration reaches 4g/L, the sensitivity of the resistivity affected by the sodium ion is reduced.
