Two aspects are shown in this paper： communication between people of different social status, genders and casual relationships, and communication between people of same social status, genders and close relationships. Therefore, the study result can be concluded like this： whether the use of indirect speech act is successful or not always influences people＇s communication significantly.展开更多

The edge crack is perpendicular to the boundary and the elastic property of the material is assumed to vary depending on thickness. By using an integral transform method, the present problem can be reduced to a single integral equation which is solved numerically. The influences of parameters such as the nonhomogeneity constant and the geometry parameters on the stress intensity factors (SIFs) are studied. It is found that the nonhomogeneity constant has important influences on the SIFs.展开更多
文摘The paper tentatively studies the function of the indirect speech act in Chinese cultural communication, namely, domestic communication. Two aspects are shown in this paper： communication between people of different social status, genders and casual relationships, and communication between people of same social status, genders and close relationships. Therefore, the study result can be concluded like this： whether the use of indirect speech act is successful or not always influences people＇s communication significantly.
