Comparing the run_time between insertion sort and quicksort shows insertion sort gives better performance when the given data sequence is in ascending order. For the nearly sorted list, whether insertion sort performs better than quicksort depends on the size of the list and the number of randomly ordered items. Compared to the insertion sort, the results show quicksort yields shorter run_time if the list is in descending or random order. The main drawback of quicksort is the worst case behavior of O(n2) comparisons when the list is in ascending or descending order. It has been shown that quicksort also performs poorly for nearly sorted list.

通过插入排序和快速排序执行时间比较显示：当序列以递增次序排列时，插入排序的表现比快速排序好；对于基本有序序列，插入排序算法是否比快速排序算法好取决于序列的大小和基本有序序列中随机分布元素的多少；对于递减和随机序列，快速排序的运行时间比插入排序好。

A particularly investigation is carried out to the observibility of in-flight alignment using numerical simulation when the aircraft performs four kinds of basic maneuvre, namely linear acceleration, yawing, pitching and rolling. The thesis summarizes the two kinds of maneuvre. Simulation results show that the precision of transform alignment reach 5 minutes in 10 seconds if the aircraft performs two well-defined maneuvres.

首先本文采用数值分析的方法研究了直线运动、航向角运动、俯仰角运动和横滚角运动对传递对准系统可观性的影响规律；再结合飞机的实际运动，给出了空空导弹传递对准时的飞机飞行轨迹；"蛇形"飞行轨迹和摇摆运动飞行轨迹，仿真结果表明：按这两条飞行轨迹机动，在10s内传递对准精度可达到5′以下。

In the studying of image segmentation, six crucial technologies havebeen developed successfully. 1 In one dimension histogram of original DRimage of luggage, there remain maximum-value wave crest havingapproximately stationary position, and the first minimum to the left of thewave crest performs excellently to be used to get rid of background of DRimage. 2 Open operation, one type of math morphology, is the right idea toerase luggage disturbance in DR image and at the same time, can be retaininteresting region appropriately. 3 After open operation, there are only a few minimums on image histogram, one of which can be to segment image furtherand achieves satisfying result. 4 Method of histogram analyzing and that oferosion performs well in the re-segmentation of conglutinative region in DRimage. 5 Method of image distance switch can ensure Luggage CT sectionautomatically obtained to have rich suspicious region information. 6 Todecompose structure element of math morphology is a way to save a great dealrunning time for automatically discerning interesting regions algorithm,apparently improving implementation efficiency.

在对图像可疑区域分割研究中，主要开发成功以下几项关键技术：1发现原始箱包DR图像的一维直方图中，均具有位置相对稳定的最大值波峰，以波峰左边第一个极小值为分割阈值，去除DR图像背景，效果非常好。2运用数学形态学中的开运算能够非常有效地去除箱子的干扰，同时能够比较好地保留可疑区域。3发现开运算后的DR图像直方图只有若干个极小值点的特点，其中用最大值波峰左边的第二个极小值点进一步分割DR图像，能够更有效地提取箱包中的可疑区域。4运用直方图分析法和腐蚀法，对粘连区域实行再分割，效果较好。5运用距离变换法，能确保自动设定的箱包CT截面包含丰富的可疑区域信息。6运用形态学结构元素分解技术，大幅度减少可疑区域的自动判别算法运行时间，提高算法软件执行效率。

With regards to the learning motive of music, after excluding the pretest influence, it is the finding of the study that the students belonging to the experimentation group score higher in the areas of "Total score","Internal goal orientation","Work value","Controlled belief","Expectation to succeed" and "Test on anxiety" than the control group, amongst which "Work value" reaches significant difference on the measurement chart; of all the students scoring high on "Selective attention" during pretest, the experimentation group scores higher than the control group on posttest scores; regarding the students with lower pretest scores, the control group performs better than the experimentation group; of the students with higher pretest scores on "Discrete attention", the posttest scores of experimentation group are higher than those of the control group; regarding students with lower pretest scores, the control group performs better than the experimentation group; on "Sustained attention", the posttest scores of the experimentation group are higher than those of the control group; on the "Total score" of multidimensional attention measurement, the posttest scores of the experimentation group are higher than those of the control group.
