单一分布

Research usejP.Haggett"s pattern of spatial structure and system, analysis technique of tourism market space and data of spot check to analyze the evolvement of spatial structure and problems of tourism development from six faces, move, path, crunode, significance of crunode, ground and diffuse. The law of the evolvement of spatial structure: First, tourism development keeps rising. Second, AR of xi"an is very big and stable, Xi"an is tourism hotspot and center. Third, origin market space sticks out east, and isn"t continuous. Fourth, tourist proportion of XAZ follows the low of distance decay. Distance decay is very obvious in adjacent zone because of little attraction. Sixth, the spatial distribution of tourist origins has become less concentrated. Tourist origins of east China develop quickly. Three problems: First, tourism development is very unbalance between Xian and its adjacent zone.

西安及毗邻地区的国内客源市场空间结构的研究，采用了英国著名地理学家哈格特描述的空间结构模式与秩序，利用旅游市场空间分析技术，借助市场抽样调查、数量分析，从运动模式、路径、结点、结点层次、地面和扩散6个层方面进行了剖析，归纳总结出5个客源市场空间结构演变规律：(1)旅游业发展整体保持增长趋势；(2)客源吸引半径大而稳定，西安市是全国性的旅游热点城市和旅游中心城市；(3)客源市场分布突向东部，呈不连续分布；(4)游客比重的距离衰减普遍存在，毗邻地区吸引物及自然吸引物吸引力较小，距离率减明显；(5)客源集中度减小，客源市场发展呈现跳跃式增长的演变规律。3个市场拓展面临的问题：(1)西安与毗邻地区间旅游业发展不平衡现象明显；(2)客源市场区位不佳；(3)旅游产品单一老化，类型单调乏味。

Especially,when there are local changes among the data,and a single parametric distribution family can\'t describe the observed data accurately,finite mixing distribution models usually make excellent performance.

特别是，当观测数据有局部变化，而单一的参数分布族无法确切地描述观测数据时，有限混合分布模型表现出色。

Secondly, the relevance feedback approach requires relevant documents to be similar to each other. That is, they should cluster. Ideally, the term distribution in all relevant documents will be similar to that in the documents marked by the users, while the term distribution in all nonrelevant documents will be different from those in relevant documents. Things will work well if all relevant documents are tightly clustered around a single prototype, or, at least, if there are different prototypes, if the relevant documents have significant vocabulary overlap, while similarities between relevant and nonrelevant documents are small.

第二，相关反馈方法需要相关文档之间相似，即它们可以聚类，理想地，所有相关文档 term 分布应该相似，相关档即用户标记的文档，同时不相关文档应该与相关文档的 term 分布不同，如果所有的相关文档都很紧凑地聚在一个单一的中心点，或至少有不同的中心点，如果相关文档有明显的词汇重复，同时相关与不相关文档相似性比较小，它才是可行的。

And after analyzing the heterogeneity of sand body, point the minor channels, especially, have important influence on the intraformational oil-flooding direction, forming and distribution of remaining oil because of their function as barrier, breaking fluid and poor permeability in fluvial sand body.

通过非均质性研究，进一步揭示了单一河道砂体内部非均质性，特别是次分流河道砂体的分布，在河道砂体内起到遮挡、阻流、特低渗透等作用，对层内水驱油方向、剩余油形成与分布具有重要影响。

Test result makes clear, different intensity grade abandons the stuff of second birth wide market that gets after concrete mix up, of the compressive strength of concrete of second birth of different origin of compressive strength; that will reduce second birth concrete significantly all be worth concrete of singler source second birth to reduce, and variance and coefficient of variation increase; to use normal school model to be opposite of compressive strength of concrete of different origin second birth distributing undertook examining, use Monte-Carlo imitate method farther test and verify should distributing the rule.

试验结果表明，不同强度等级废混凝土混和后得到的再生粗集料，将显著降低再生混凝土的抗压强度；不同来源再生混凝土抗压强度的均值较单一来源再生混凝土减小，而方差和变异系数增大；采用正态分布模型对不同来源再生混凝土抗压强度的分布进行了检验，利用Monte-Carlo模拟方法进一步验证了该分布规律。

Aimed at the complexity of fluvial strata, such measures as well cyclical comparison, step control and geological analysis of reference beds have been applied. Moreover the paper has developed a set of methods the techniques to extract the parameters controlling the formation of intra-sandbody thin interbeds. The present study has examined how thin interbeds affect the frame property and heterogeneity of individual sandbodies; revealed the permeability space distribution mode of meandering distributary channel's single side lithosomic body and straight distributary channel's aggrading lithosomic body. Through applying the distributary channel sandbody structural unit classifying and identifying method achievement, some horizontal wells have been deployed to dig the residual oil in the top of hick pay zone in the xing8-9 area, which shows better effect after they have been put into production.

So far, no single method or combined methods can unambiguously provide complete quantitative analyses of lignin distribution. Therefore, further studies are needed to explore the complex structure of lignified cell wall.

迄今为止，没有一种单一的方法或联合方法能清晰明确地提供完全的木素及其分布的定量分析，对木素及其分布研究还有待于进一步完善。

An assumed Gaussian tail is addedonto the HO distribution.
