查询词典 scale factor

The effects of the structure constant of the refractive index fluctuations Cn2 and the inner scale of the turbulence l0 on the M2 factor have been analyzed quantitatively. Consequently, a new method for determining the characteristics parameters of the turbulence based on the measurement of the M2 factor by experiments has been proposed.

The economic growth accounting of China's provinces between 1990 and 2004 finds some results like the following: no matter whether human capital was introduced or not, there were technological inefficiencies in most provinces'economic activity which were pure technological inefficiencies or scale technological inefficiencies; technological change, capital deepening and human capital accumulating all promoted labor productivity, but technological efficiency change played a negative role during these years as a whole; the descending order of provincial difference of labor productivities'changes brought out by each factor was technological change, capital deepening, technological efficiency change and human capital accumulating; each province's pure technological efficiency change or scale efficiency change not only had different size, but also different evolution route.

中国各省在1990～2004年间的经济增长核算结果表明：不论是否引入人力资本，大多数省份的经济活动都存在着技术无效率，这既包括纯技术无效率，也包括规模无效率；技术进步、资本深化和人力资本积累都促进了劳动生产率的提高，而技术效率的变化整体上来说在其中起阻碍作用；各因子引致的劳动生产率变化的省际差异从大到小依次为技术进步、资本深化、技术效率的变化和人力资本积累；各省的纯技术效率或规模效率的变化不仅大小不同，而且它们的演变路径也不一样。

在研究中主要对影响船舶大型化规模效应的几个限制因素进行了分析研究，得出船舶大型化规模效应受很多因素的限制，最重要的因素是港口的装卸效率，也就是说只有高效率的港口装卸和管理效率才能充分体现集装箱船舶大型化的规模效应。

Finally, the calculation process of CGR graphic's multi-fractal analysis was studied. the scope of choice of the weight factor and the scale invariance range were discussed, the weight factor can be chosen as ? 15≤q≤50; multi-fractal spectrum and generalized dimension of different sequence were calculated, multi-fractal spectrum and generalized dimension in different scales of different sequences were compared, it was found that multi-fractal spectrum and generalized dimension can show different levels of fractal characteristics of CGR graphics of DNA sequence, which can distinguish more complex structure of sequences.

The major findings of this research can be summarized as follow:1 The comparison of USPED model-estimated amounts of soil erosion based on four different scales of DEMs (1:250,000, 1:50,000, 1:10,000, and 1:5,000) indicates that 1:50,000 -scale DEM is almost as good as higher-resolution DEM data in providing needed topographic information for assessing soil erosion, whereas 1:250,000-scale DEM underestimates soil erosion mainly because rill erosion and sheet erosion are greatly underestimated.2 Since precipitation is the most important forcing factor for soil erosion, the accuracy of soil-erosion estimates understandably relies on the adequacy of spatially distributing point-observed precipitation data.

取得的主要成果如下：(1)基于四个尺度(1∶250，000，1∶50，000，1∶10，000，and 1∶5，000)的数字高程模型和USPED模型计算的土壤侵蚀结果对比表明，1∶50，000的数字高程模型与更高分辨率数字高程模型提供了几乎一样的用以估算土壤侵蚀所需的地形信息，而1∶250，000的数字高程模型，由于过低的估算了细沟侵蚀和片蚀，从而过低的估算了土壤侵蚀的总量。
