The introduction has several contents as follows : outlines the geological and chronological range ; reviews brief research history of bronze arrows ; makes the intention clear and what means would be taken , defines standard that would be used in typological classification ; makes textual research on subjects and collects all previous appellations for arrows , then raises appellation standard this paper would take . chapter one : researches on bonze arrows in xia - shang dynasty . in this part , on the basis of unearthed bronze arrows in xia - shang dynasty , the author firstly makes typological analysis on bronze arrows patterns , divides them into two sorts , each had analysis on types separately 本文以各不同时期考古出土的青铜镞为研究对象,对青铜镞的形制做类型学的分析,并进行了分期研究,通过对青铜镞分布区域的研究,解析不同区域青铜镞的文化因素构成,最后将研究结果汇总,建立起青铜镞的编年序列,比较深入地探讨了青铜镞在形制上的演进与其在军事上的意义,考证了青铜镞不同的形制所具备的不同功能,并对先秦时期箭在军队使用弓箭的兵种与非实战用的礼射与弋射用箭的情况进行分析探讨。
The automat i c mon i tor i ng on the i oad i ng s i tuat i on of mov i ng f re i ght tra i ns should be implemented to ensure the operation security of railway fre i ght . the paper presents a new algorithm for freight train image segmentation with the aim of minimizing missing gauge - exceeding detection rate based on the image segmentation theory . the prof i le of the freight train and cargoes on the image is obtained with the arithmetic and whether cargoes exceeding the gauge or not is concluded by the location of the freight train and cargoes on the image 本文以数字图像处理原理中图像分割理论为基础，结合货车装载状态监测的实际情况和货车装载状态监测系统对图像分割的要求，以保证超限漏检率最小为目标，给出了货车图像自动分割的算法，获得货车及其所装载货物的分布区域，再根据该分布区域，得出货车装载状态是否超限的结论，从而实现对运行中货车的装载情况的自动监测。
In order to solve this problem , the distribution of the force was studied . with analyzing the data of ship launching , the paper educes seven typical distribution forms , include uniform distribution , sine distribution ( 1 / 2 amplitude ) , trapezoid distribution , right triangle distribution , sine distribution ( 1 / 4 amplitude ) , parabola distribution , isosceles triangle distribution 主要有七种分布形式，包括分布趋势较平缓的均匀分布形式、正弦( 1 2波形)分布形式、梯形分布形式；峰值出现在滑道最前端的直角三角形分布、正弦( 1 4波形)分布、抛物线形分布；还有峰值出现在分布区域中间的等腰三角形分布。
