To fulfill the need of the application of RP technique in medical domain, reverse CAD modeling from medical cross sections is systematically studied in this dissertation. Firstly, Some algorithms related to the research of this dissertation are studied. New algorithms for orientation and inclusion test for simple polygon, an error constrained automatic faring algorithm for B-spline curve and a theorem regarding the termination criterion for subdivision of triangular Bézier patch are proposed. Then based on similarity between contours of adjacent sections, a methodology for surface reconstruction from cross sections is presented. Finally, a virtual measuring method is proposed.

本文针对RP技术在医学领域应用的需要，系统研究了基于医学断层轮廓数据的反求CAD建模理论和方法：(1)在基础算法研究部分，提出了简单多边形方向及点在多边形内外判断的新方法、三角Bézier曲面片离散的误差控制定理和一种带误差约束的B样条曲线的自动光顺方法；(2)提出了一种基于相邻层轮廓相似性的医学断层轮廓数据曲面重构方法；(3)提出了一种称为"虚拟测量"的曲面模型处理方法。

In 1929 some improvements were announced to what was now called the '33/8" Super Exe': the mandrel bore was increased to 1/2"(but 17/32" in reality, so allowing a 1/2" bar to pass clear through), the saddle carried a conventional compound slide rest with a T-slotted cross slide and swivelling top slide and, happily, the 10 tpi Acme-form cross feed screw had the outer flat rim of its handwheel engraved with a micrometer scale - an improvement mirrored simultaneously on the 4-inch lathe.

在1929年宣布了一些改进的话现在称为'33月8日"超级可执行'：在轴孔增加到1 / 2 "（但17/32 "在现实生活中，这样使1 / 2 "酒吧，通过明确的通过），鞍进行常规复合幻灯片其余的T型槽交叉旋转顶端幻灯片和投影片，并令人高兴的是， 10 TPI公司的Acme形式跨了饲料螺钉外单位辋其手刻有一微米尺度-改善镜像同时在4英寸车床。

Monitoring mixes the sneaks in or out of a country that leaves the big range area such as subtense condition for real low now specific power consumption and less investment to call the police automatically, designed a kind to use the supervisory system of cross the boundary illegally of cross the border of the technology such as short message business, infra-red laser.

梗概： 为实现在低能耗和较少投资下对边境等大范围地区的越境监控和自动报警，设计了一种采用短信业务、红外激光等技术的越界越境监控系统。

The calibration curve of the SM2-Kit with standard SM2 inhibitor was typical sigmoid curve fitted to the four parameter logistic equation with the linear detection of 0.625 μg/L to 80.0 μg/L (R2=0.9911), the sensitivity of 0.9 μg/L, the IC50 of 5.82 μg/L and the detection limit of 1 μg/L. The recoveries of SM2 spiked in pig feed were 83.4 %, in pig urine were 89.5 %. The precision and accuracy of the assay as determined by inter-assay and intra-assay coefficient variation was both below 15 %. The SM2-Kit generally had 2.08 % cross-reactivity towards sulfamerazine and little or no cross-reactivity towards other sulfonamides. The dilution solution of SM2 had no effect on results of SM2-Kit. The validity of SM2-Kit in 4 ℃ was above six months.

研究结果表明，SM2-Kit的标准曲线呈典型的S型，相关系数R2=0.9911，符合4参数logit曲线拟合，线性检测范围为0.625 μg/L～80 μg/L，灵敏度为0.9 μg/L，半数抑制浓度(IC50)为5.82 μg/L，检测限为1 μg/L；饲料样、猪尿样的平均添加回收率分别为83.4 %、89.5 %，平均批内和批间变异系数均低于15 %；SM2-Kit与磺胺甲基嘧啶的交叉反应率为2.08 %，与其它磺胺类药几乎没有反应性；基质对SM2-Kit的检测结果影响不大；试剂盒在4 ℃可保存6个月。

The ratio of the vertical load distributed between the arch rib and the tie beam of the two schemes is the same. For the integral girder deck scheme, the longitudinal beams and the deck slab of endure more axial force compared to the ballast girder deck scheme, especially to the deck slab with a conspicuous increase of the axial force and higher stress, and the tie beam endure less. The force-bearing characteristics of the cross beams under the integral girder deck scheme is obviously better than that of the ballast girder deck scheme, especially at the two ends of each cross beam.

在受力上，与道碴板桥面方案相比，整体桥面方案竖向荷载在拱肋和系梁之间的分配基本相同，混凝土板和纵梁分担的纵向力则相对更大，尤其是混凝土板，增幅较明显，应力水平整体较高，系梁分担的纵向力则得到减小，横梁的受力状况整体桥面方案明显优于道碴板桥面方案，特别是在梁端处。

In order to discuss the possibility of torpedo(diameter: 534 mm) swim-out launching by the submarine torpedo tube in service, an interior trajectory model was set up in consideration of different resistances and the fact that the area ratio of the circular clearance cross-section of torpedo tube in service to the torpedo cross-section is small. The pressure difference of seawater compensation was defined and added to the model as a resistance parameter, and the launching process was analyzed.
