As the research method as concerned, this research collects materials and information from three different villages and organizes them in series village comparison way , which is a new attempt in the domestic present research of Pinghua group as well as the urbanization. Meanwhile, through this kind of comparison research, this thesis proposes the"disequilibrium change"concept in another kind meaning and points out that there would be disequilibrium change at different points in an identical social culture, which will promote the anthropology's understanding of change's diversity.

在研究方法上，本研究从三个不同的点收集资料，采用村落连环比较的方式组织材料，是目前国内有关平话人研究以及城市化研究的一次新尝试；同时，通过这种比较研究，提出另一种意义上的"非均衡"变迁的概念，指出了同一社会文化在不同点上变迁的不均衡现象，增进人类学有关社会文化变迁多样性的理解。

Change detection technology is an important method of remote sensing application field. Generally,it is classified as spectrum comparison method and post-classification comparison method.

变化检测技术是遥感应用研究的热点领域，通常将该技术归为两类：光谱直接比较法和分类后比较法。

Three TM/ETM+ image (1999, 2002, 2007) were used. Land use change areas were determined by using two change detection techniques of post-classification comparison and spectrum comparison. The resultant change images obtained by the two change detection methods were overlaid to obtain more accurate change information.

本研究选取了1999年、2002年与2007年3期的TM/ETM+遥感图像，采用分类后比较法对沽源县1999~2007年的土地利用变化进行信息提取，再通过两者的叠加分析，获得了较为理想的变化监测结果。

The digital analysis of the six standard samples of the Al-based alloy with different content of Cd, and the probe into the quantitative analysis that employs the spectrums of Cd 508.5 nm as the analysis spectrum, Cu510. 55 nm and Fe510.75 nm as comparison spectrum separately, indicate the positive relationship between the content of cadmium and the intensity ratio of the analysis and comparison of spectrum.

对6种不同Cd元素含量的铝合金标准样品进行了数字化分析测定，探索了选用Cd 508.58nm谱线作为分析谱线，分别选用Cu510.55nm和Fe510.75nm谱线作为比较谱线进行定量测定的方法，数据显示分析谱线和比较谱线的强度比值与Cd元素含量成正比关系。

The visible spectrum of Mo in Ti-based alloy was analyzed by a digital spectroscope. Mo 553.31nm and Ti 551.44nm were selected as spectral lines for analysis and comparison. Samples of Ti-based alloys with different Mo contents were analyzed quantitatively. The data indicated that the ratio of intensities between analytical spectrum and comparison spectrum has a positive relationship with the content of Mo.

Because different cell lines may show various levels of susceptibility to adenovirus infection and virus production, non-selectively replicating wtAd5 was used to be a comparison with the tested conditionally replicating adenovirus CNHK500.ONYX-015, the first replication-competent adenovirus entered into clinical trials was also used to be a comparison. We used virus proliferation assay, cell viability assay and western blot to evaluate the proliferation and cytolysis selectivity of CNHK500. Results demonstrated that the CNHK500 virus proliferation multiples in breast cancer cell lines after 48 hours is similar to that of wtAd5, ONYX-015 virus proliferation ability is less than that of CNHK500 in cancer cells.
