The position and size of the monochromator, focusing curvature radii and tilting angles of the germanium focusing monochromator under different different take-off angle, size and divergency of the second collimator and intensity loss due to the use of it were determined. The neutron flux at different wavelength, under different reflection and take-off angle of the monochromator and divergency of the first collimator, were given. The simulation on the aperture used for limiting beam size in front of the sample showed that, smaller the size of the aperture and further the distance from the aperture to the sample, greater the loss of the intensity and more serious the spread of the beam along vertical direction at the sample position which makes the practical sampling volume greater than expected.

This means that the understanding of agricultural activities is still an important element in understanding modern rurality.
乡村性是描述、判断乡村之所以为乡村的标准,过去许多研究倾向透过实证取径的指标测量,描述乡村性组成之元素,对这样的研究而言,农业生产仅是对乡村性探讨中的一个变项,在农业活动已然式微的今日乡村中,有些学者认为农业已失去在乡村性讨论上的重要性,然而本研究从社会再现的观点思考乡村性,认为乡村居民日常言语所透露出的概念、意象、符号可作为描绘乡村形象的依据,而乡村民众日常言语的表现,又受其生活经验、所接收资讯等的影响,对部分生活在乡村的居民而言,仍视农业为其最重要的生活经验,这说明了对农业活动的理解,仍是探讨乡村性一个重要的面向。

Secondly, two physical models were constructed, which could model rough surface and describe the features of the earth surface, such as chine, neck, valley and hill, etc. According to difference method, the ""true"" volume of the physical models were measured, which was 13260cm3 and regarded as the analysis foundation of the precision of the volume that was calculate by DEM. The discrete dada of the models on a regular spacing of 1cm were collected by 3SPACE FASTRAK and the DEM was obtained by interpolating the discrete dada through GIS software. Based on the volume of the models calculated by DEM, different interpolating methods (IDW, Spline, Natural Neighbor, and Kriging) and variation of grid spacing of data were compared and their effects on precision of volume calculation were analyzed.
