In this paper, based on the in\|situ high\|resolution observation data of GAME\|Tibet, the soil energy\|moisture distribution and the melting\|freezing progresses and their effects on seasonal shift were preliminarily discussed.The soil energy\|water distribution and freezing\|melting processes varied at different sites in northern part of Tibetan Plateau. The temporal and spatial variation of the soil moisture content is more complex than that of temperature. The soil moisture content increased with depth in certain layers but decreased in other layers. The freezing and melting processes and the temperature distribution were largely influenced by the existence of higher soil moisture content layer. During summer monsoon, the soil moisture at 10cm at all sites is relatively high, but the spatial difference existed. Generally speaking, the shallow layers start to freeze in October and to melt from April at all sites, with about 6 months frozen period. However, the beginning time of freezing\|melting and frozen period varied at different sites.展开更多

The results show that the valuation of sensitivity to acidification of lakeweters and streamwaters often disagree with the actual circumstance only by the value of buffer capacity. “Acidification capacity”is firstly proposed to assess the sensitivity to acidification in this paper. Compared with other methods, this methods, this method not only can assess the sensitivity to acidification more effectively, but also can predict the time quantitatively when the acidificafion occures in lakewaters or streamwaters due to its consideration for the quantity of various components and their interrelation and interaction as far as possible.展开更多

Based on analyzing the process capability indices, a production department can trace and improve a poor process to enhance quality levels and satisfy customers. The process capabilit y analysis can also serve as an important reference for making decisions for imp roving the global quality of all products. Since C p and C pk are failed to account for process centering, the index C pm is developed. The index C pm takes the process centering into consideration and is su itable for the processes with nominal-the-best type. There are other indices l ike C pu and C pl, and those indices are used for unilateral s pecification processes. Chou (1994) developed a procedure using estimators of C p, C pu and C pl for practitioners to determine whether two p rocesses are equal capability or not. For bilateral specifications processes, i ndex C p is failed to measure process yield and process centering. Thus, th e index C pm is used to develop a similar procedure for practitioners t o determine whether two processes are equal capability or not. The decisions mad e using the procedure to select the better supplier are, of course, more reliabl e.展开更多
