查询词典 at the cost

The great tour purchasing power is the drive power of promoting the region's tourism developmentln the regional space, scale economic and regional separation are one of the basic characteristics of promoting tourism industry, So we must arrange the regional tourism industry with a systematic method and give prominence to the central city. For its outstanding area in the regional space, central city has evident superiority in the regional ecnomic development, and has echelon between central city and its periphery scennic spots, which is the inducement mechanism of tourism industry's arranging, developing and advancing step by step. For the law of diminishing marginal utility and the theory of equilibrium, the max utility equilibrium of tourism consumption be at the point of tangency of undiscrepancy curve and the cost budget curve.

中心城市居民巨大的出游力是拉动其周边旅游地发展重要的内在驱动力；由于地缘关系，区域规模经济与地域分割并存，是旅游产业运动的一个基本特征，为此必须对区域旅游经济进行系统化布局，突出中心城市的产业中心性；因其区位条件独特，中心城市在区域经济发展中居于明显的优势，与周边城乡部位存在经济发展上的梯次性，这种梯次性是区域旅游生产力布局、产业发展梯次传动，最终整体联动的经济诱导机制；根据边际效用递减规律和旅游者最大效用均衡理论，旅游消费效用最大化的均衡在无差异曲线与开支预算线的切点(即旅游目的地选择的最佳位置)上，且随着边际效用递减，目的地选择的最佳位置向远离中心城市方向移动，这就是中心城市与周边旅游地互动关系的经济学解释。

In the view of above-mentioned reasons, two new technologies were researched and developed by changing the distribution of heating units, the construction of furnace and relevant processing parameters in this paper. One of the technologies is multi-core heat technology for fabricating polytype industry SiC products, another is reactant heat without core for synthesizing SiC with high performance and added value at low cost by common industry raw materials.

基于上述背景，本文通过改变发热体形式、炉体结构和相应的工艺，研究开发了多炉芯发热法制备多品种工业SiC产品和无炉芯反应料发热法以普通工业原料低成本制备高性能和附加值的SiC产品的技术。

Pillared montmorillonite, as a representative of Sandwich like pillared interlayered clays ,caught many scientist"s attention not only because of its special structure of two-dimensional sheets but also its excellent activity of catalysis and adsorption. It is well documented that the method to prepare PILM, ion-exchanging, needed a long periods and was affected by many factors, and that the product had low thermal stability especially hydro-thermal stability which was the primary obstruction of its using in large-scale production. At the same time, PILM was well documented prepared with Na-montmorillonite, while there were a few documents about PILM prepared with Ca-montmorillonite. The large cost of remodel of Ca-montmorillonite to Na-montmorillonite was another obstacle of the application of PILM, while Ca-montmorillonite was widely distributed in nature, as a result, to prepare PILM with Ca-montmorillonite has practical significance. What"s more, PILM was mainly studied as a catalyst in oil refining process till now, but rarely documented in other catalysis reactions, especially in coal liquification filed which also needed high activity catalyst.

以柱撑蒙脱石为代表的具有"三明治"结构的柱撑粘土矿物因其特殊的二维孔道结构和优良的催化和吸附性能近年来成为国内外广泛关注和研究的热点，但是目前国内外大量报道的PILM制备大多采用离子交换法，生产周期很长，影响因素很多，并且产物热稳定性不够高，特别是水热稳定性较差，这是其不能在实际中大规模生产和应用的主要障碍，因此制备一种高稳定性的PILM意义非常；文献中大量报道的都是钠基蒙脱石合成的柱撑粘土矿物，传统的离子交换法必须将钙基蒙脱石钠化改型，其成本相当高，而自然界中大量存在的却是钙基蒙脱石，直接用钙基蒙脱石合成柱撑粘土矿物有很现实的意义，但目前这方面的报道却很少见；另外，迄今为止，PILM作为催化剂的研究领域主要在石油的炼制中应用，而在煤炭的液化中却鲜有报道，如果能在煤炭转化领域应用这一成果，其影响也将是相当大的。
