查询词典 uniform approximation

The results showed that spherical BaCO3 particles with low reaggregation and uniform size of about 100nm could be prepared by using solid-state reaction of Ba(NO3)2 and Na2CO3 at room temperature; while stick shape particles, whose size is not uniform, were obtained for the BaCl2 2H2O and Na2CO3 system. For the Ba(NO3)2 and NH4HCO3 system, the products are spherical whose average size is about 200nm.

82 Times as high as the flow rate at the inlet; the velocity profile in the lower region is relatively uniform, and changes at the exit from a parabolic shape towards a plug flow as Re increases; The strong circulating flow in the upper region is very favourable to evaporization of heated fluid because it not only forces all the heated fluid to flow through the liquid surface and, therefore, to evaporate effectively, but also causes a large part of fluid to recirculate to the liquid surface and, therefore, to get a second opportunity of evaporization. In addition, the uniform velocity profile in the lower region is also favourable to crystallizing process.

轴向进料蒸发室进口管侧上方有强烈的循环流存在，循环流流量为进口流量的1.48～1.82倍；循环流下部流速分布较均匀，出口区流速在低Re时为抛物线分布，高Re时接近活塞流；强烈循环流的存在不仅迫使加热流体全部流经液面及其附近进行充分蒸发，而且之后还使相当部分流体再次循环回到液面及附近进行二次蒸发，对蒸发操作十分有利；蒸发室下部流速的均匀分布亦有利于蒸发结晶过程。

In the research on the backward-wave oscillation suppression the startoscillation current which is derived from Two-wave theory approximately is given up. Four typical un-uniform slow wave structures start-oscillation current equations are derived by backward-wave amplifing gain expressions with the Two-wave theory. Then the start-oscillation current rates I〓/I〓 between ununiform circuit and uniform circuit of the four structures have been got.

In the early research, HSV color space is considered to be uniform with human's vision model. Along with the analysis of HSV space, we find the uniform is limited and propose a new quantization method, which is more reasonable to human's vision model. Without decreasing the retrieval performance, the scheme non-uniformly quantizes the color space into 36 bins. Because the quantization result has only 36 bins, the computational complexity is decreased effectively while the performance increases. Relevance feedback is an interactive technique in the process of CBIR.
