I. INTRODUCTIONThe pegmatites discussed in this paper occur entirely in the granite region of Suchou (Wuhsien), Kiangsu and most of them are found within the marginal zone of the said igneous body. Although much work has been done on the Suchou granite by former geologists [19; 13; 21; 12], there is no literature dealing particularly with the pegmatites which are in intimate  相似文献   

A SUGGESTION OF A NEW METHOD FOR GEOLOGICAL SURVEY OF IGNEOUS INTRUSIONS     

李四光  仲揆 《地质学报》1924,3(2)

It may be safely presumed that few of us who have worked in the field as a geological surveyor would dissent in making an open confession of our unfortunate attitude towards igneous rocks particularly those of a massive form. These obstacles, as one is apt to regard them, are the unruly bodies  相似文献

The New Form of Time-Dependent Mild Slope Equation for Random Waves     

Zhang Yonggang  Li Yucheng Teng Bin Doctor Degree Candidate  The National Key Laboratory of Coastal  Offshore Engineering  Dalian University of Technology  Dalian Professor  The National  Key Laboratory of Coastal  Offshore Engineering  Dalian University of Technology  Dalian Associate Professor  The National Key Laboratory of Coastal  Offshore Engineering  Dalian University of Technology  Dalian 《中国海洋工程》1995,(4)

The mild-slope equation derived by Berkhoff (1972), has widely been used in the numerical calculation of refraction and diffraction of regular waves. However, it is well known that the random sea waves has a significant effect in the refraction and diffraction problems. In this paper, a new form of time-dependent mild slope equation for irregular waves was derived with Fade approximation and Kubo's time series concept. The equation was simplified using WKB method, and simple and practical irregular mild slope equation was obtained. Results of numerical calculations are compared with those of laboratory experiments.  相似文献
