The results of numerical experiments, using the four-dimensional variational data assimilation system of the nonhydrostatic mesoscale model MM5, show that: the tangent linear model and adjoint model conducted by keeping the "on-off" switches the same as the basic state, can provide a good approximation of the first-order information to the NLM perturbation and a good descent direction for the minimization procedure; switching on and off at every other time step in the Kuo cumulus parameterization scheme don"t impact the convergence rate of cost function; the existence of the switches don"t impact improvement to the MM5 model rainfall prediction because that not only specific humidity ,but also wind, temperature and pressure are assimilated into the model.

NEXT week Henri Proglio will become the boss of EDF Group, the state-controlled French firm which is the world's biggest listed utility and operator of nuclear reactors. With its proud corporate culture, its devotion to long-term planning and its powerful unions (the Confédération Générale du Travail jointly runs the firm, in effect), EDF is sometimes described as a miniature version of France itself. Last year it began a vigorous campaign to build nuclear plants around the world. But to the dismay of advocates of a nuclear renaissance, the cost and complexity of embarking on several big projects at once is weighing on the firm, despite its size and government backing.

下周Henri Proglio将成为EDF集团的老板，EDF集团是国家控股的法国公司，它世界上在册的最大的公用事业和核反应堆运营商，考虑到EDF荣耀的企业文化、对远期计划的投入和强有力的联盟（实际上是由Confédération Générale du Travail联合运营该公司），有时它可以被看作是法国本身的微缩版，去年，她开始了一场强有力的遍布全球的核电厂的建设，但是令核能源复兴倡导者沮丧的是立刻着手几个大工程所需的花费和复杂程度给公司带来不少压力，尽管集团有相当的规模并拥有政府的支持。

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。
