时间划分

According to the regulations above, the paper presents the virtual price and profit function in the course of selecting cars for the departing trains and the model of the grouping cars into arrival trains.

在车流推算的基础上，从应用计算机模拟区段站调度员思维的角度出发，通过分析车列占用调车机车时区集合的特点，使用划分时间片的方法建立合适的调车机车安排的图论模型，将调机运用问题转化为顶点具有加权的图的K-着色问题。

One of his ships was called the Jolly Roger and he named his flag after it.

从时间上划分的，我们一般看成人类，美国摩根提出的进化论的文化观，人类总要经过三个阶段：一个是蒙昧，第二是野蛮，第三是文明。

According to the concept of substructure and Time domain FEM method, substructures time integration method is presented in this paper which is symplectic conservation.

对此，本文根据子结构概念和时间有限元方法，根据结构间界面的物理量关系划分子结构，提出保辛的精细积分子结构方法。

Thirdly, it introduces the theory of the imagesegmentation and frequent segmentation technique. The aim of the imagesegmentation is to mark off the interested region of the image, which is done to thecorresponding image processing to reduce the operation time and save the storagespace. At last, it mostly introduces the compress technique based on the wedgelet, andcompares the CART model which is introduced by Donoho and the improved modelby Romberg et.al. with the model of the article, then compares the image ofprocessing based on the three methods.

然后，介绍了图像分割理论和常用的分割技术，图像分割的目的是划分出感兴趣的图像区域，进行相应的图像处理，减少运算时间和节省存储空间；最后，主要介绍了基于伸长小波压缩的技术，将目前主要的算法----Donoho提出的CART模型和Romberg等人基于此的改进模型，与本文所提出的算法模型进行了比较，并对三种方法处理的效果图作了详细的比较。
