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。

主要内容及结论：1充氡后利用计算机连续进行电离电流累积测量，得到了精细的电流随时间的变化曲线，可清楚看出氡及其子体的生成衰变造成的电离电流的生长—稳定—衰减过程，与理论计算值进行了比较，由电离电流衰减速度的变化得出氡吸附作用的影响，并测量到电离室冲洗后氡的反扩散现象；2由已知活度的标准源定出相对测量的刻度系数K值，K=24.62 Bq／pA，对同一个监测源以半年为周期进行多次测量后得出稳定性符合要求；3通过测量电离电流和气压的关系曲线以及不同气压下的饱和曲线，确定了常规的工作条件；4测量了盐酸清洗电离室内表面降低本底的效果；5不确定度分析表明相对测氡的扩展不确定度(k=2)小于5％，由本底涨落得出探测下限为0.5 Bq；6理论上对壁损失修正进行了计算，实验上保持电离室工作在饱和区的情况下，测量了不同气压下电离电流的变化，从中得出了壁损失随气压变化的规律，可以看出，电离电流的实测值和计算值随气压变化规律基本一致；当气压大于125 kPa时，端效应等其它因素造成的影响不大于2％，因而在此工作条件下，测量电离电流后通过计算修正壁损失可以实现近似的绝对测氡，提出了进一步提高绝对测量准确度的方法。

Single capital in the profit-driven motives chases excess value. Law of pro-rata to the total social labor in a competitive relationship regulates the total social capital. But in a capitalist economic relations law of pro-rata to the total labor failed to play its role. In currencies economic relations currency accumulation may be the same with the actual accumulation, may also inconsistent. In the law of organic composition of capital rising income distribution led to the impoverishment of the working class and cyclical decline in effective demand.

本文指出马克思通过价值理论、货币理论、社会再生产理论和收入分配理论的分析，阐明了资本主义宏观经济的运行：单个资本在利润动机的驱动下，追逐超额剩余价值；按比例分配社会总劳动规律在竞争关系中，对社会总资本起调节作用，但在资本主义经济关系下，按比例分配总劳动规律不能正常发挥作用；在货币经济关系下，货币积累与实际积累可能一致，也可能不一致，加剧了总劳动分配比例的不合理；在资本有机构成提高的作用下，资本主义收入分配关系导致工人阶级贫困化，有效需求周期性下降，资本主义经济危机不可避免。
