Under conventional N fertilization and irrigation condition, N2O emissions during 2001-2002 and 2002-2003 in winter wheat and summer maize rotation system were 1959 g N hm-2 and 1250 g N hm'2, respectively; and 68%-86% of N2O emission occurred in summer maize growth season, the emissions mainly occurred in 2 weeks after N fertilization and irrigation. The highest flux rates were 5.06 mg m-2 d-1 and 5.60 mg m-2 d-1 in the rotation period of 2001-2002 and 2002-2003, which were happened at the ten-extended leaf stage in summer maize season when top-dressing N fertilizer was applied.

In this study, a commercial CAD/CAM Software is used to plan and generate the multi-axis tool path, and a table rotating/tilting type five-axis machining center is used to perform the experimental machining operation. The material of the die studied is NAK 80 die tool steel, and the geometries are modeled as concave and convex spherical surfaces. Milling parameters considered are spindle speed, feed rate, and different types of cutting tool path. The experimental results show that the surface roughness for concave spherical surface is about 0.247 μm and roundness is about 0.0283 mm and the surface roughness for convex spherical surface is about 0.250 μm and spherical roundness is about 0.0551 mm under the cutting conditions mentioned in this study.

本研究的实验方法与步骤包括利用商用CAD/CAM系统针对实验对象规划三轴/五轴同动加工路径，并经后处理程式转换，在本实验室之平台倾斜/旋转型之五轴加工机上进行实验，实验对象为NAK80模具钢材料之凹与凸球形曲面之加工，此外考虑的切削条件有主轴转速、进给速度、加工路径等，在本研究所设定之最佳切削条件下，凹球形曲面之真圆度约为0.0283 mm，粗糙度为0.247 μm，而在相同切削条件下，凸球形曲面之真圆度为0.0551 mm，粗糙度为0.250 μm。

A polycapillary X-ray lens with spot size of 41.7 μm was applied to focus original X-ray and a slit of 50 μm was located in front of the detector to improve angle resolusion.

为了提高入射X射线的强度并提高系统的空间分辨率，选用焦斑为41.7 μm的会聚透镜对原级X射线进行会聚，并在探测器前加上50 μm的狭缝以提高掠出射角扫描的角度分辨率。

Taking no account of aberrations,the optical spot size of the lens whose diameter is 1.80 mm is 1.2 μm.Compare the measurement value which is 1.5 μm with the theoretical one,they are almost identical with each others.It also proves the theoretical analysis is reasoned.
