这本书延伸科学畅销书“全球定位系统 - 理论与实践”，以涵盖全球导航卫星系统（GNSS），包括俄罗斯GLONASS，欧洲伽利略系统，以及其他系统。书是指在一般意义到GNSS来描述各种现有参考系统的坐标和时间，卫星轨道，卫星信号，可观察，数学模型的定位，数据处理，和数据转换。本书是一本大学级入门教材，目的是作为学生的参考以及为专业人士和科学家在大地测量领域，测量工程，导航和相关学科。(This book extends the scientific bestseller GPS- Theory and Practice to cover Global Navigation Satellite Systems (GNSS) and includes the Russian GLONASS, the European system Galileo, and additional systems. The book refers to GNSS in the generic sense to describe the various existing reference systems for coordinates and time, the satellite orbits, the satellite signals, observables, mathematical models for positioning, data processing, and data transformation. This book is a university-level introductory textbook and is intended to serve as a reference for students as well as for professionals and scientists in the fields of geodesy, surveying engineering, navigation, and related disciplines.)

Delphi截屏，抓图，抓屏程序，支持连续抓屏，效果不错，再完善一些，加入鼠标选框截图的功能，我想那就更完善了。PS注：本来想做网络抓屏，但似乎没准备好，就先做了这个本地抓屏的程序。

邮票问题:设一国家发行n种不同面值的邮票，并且每封信至多允许贴m张邮票，对于给定的m,n值，写一个算法求出从邮资1开始在增量为一的情况下可能获得的邮资值的最大连续区域以及获得这个区域的各种可能面值的集合。如，当 n=4,m=5,若有面值为（1，4，12，21）的四种邮票，则邮资最大的连续区域为1到71。还有其他面值的四种邮票可组成同样大小的区域吗-stamp issue : Let a national issue n different denominations of the stamps and letters each allow up to m stamp affixed, to the m, n, write an algorithm derived from a postage in an increment of the circumstances, may obtain a postage value of the maximum continuous access to this region and regional various denominations could assemble. For example, when n = 4, m = 5, if the values of (1,4,12,21) of the four stamps, postage largest regional consecutive 1-71. There are four other denominations of the stamps can be the same size as the composition of the region? ?
