It is important and necessary for people to know the differences between Chinese and western table tanners, which can help to have a better understanding of the dietary culture in two cultures. Learning and applying table manners correctly can not only help to prevent gaffe, but also develop the ability of cross-culture communication and avoid cultural conflicts.展开更多

[ Method] Depending on analyses of the radar observation data, hail shooting data and artificial hail suppression operation data in the middle region of Inner Mongolia ( represented by Huhhot) from 1990 to 2007, and combining capability of the artificial hail suppression operation tool (" 37" anti-aircraft gun), nucleation rate of the catalyst and suitable catalyst volume in hail cloud per unit volume, objective evaluation of the manner and effect for artificial hail suppression operation in the area was obtained. [ Result] It was exacter to distinguish shape and intensity of the hail cloud, but it was uncertain to distinguish height of the hail cloud, when selecting operation target cloud. Operation height was still lower, and perfect seeding height couldn't be attained. Operation occasion was controlled well, but there still were phenomena of the late operation. Shell amounts of the operation were few obviously, needing to increase shell amount or to improve nucleation rate of the catalyst. [ Conclsion] Syntheti- cally, manner of the artificial hail suppression operation in central Inner Mongolia was suitable, and total efficiency was about 85%.展开更多

Results showed that HCH content changed during 0.012 7 -0.069 8 gg/L in Jiaozhou Bay and was very low. Seen from HCH content, water in Jiaozhou Bay was cleaner, and HCH did not have seasonal change. Horizontal distribution of HCH showed that HCH was directly input into offshore water only by surface runoff, and there was no river input. HCH was area source and was from land. In Jiaozhou Bay, the maximum HCH was gradually becoming smaller, and input manner also changed. HCH migration changed from river input to river and surface runoff input to final surface runoff input.展开更多
