2The speed of creating random series used irrational fraction arithmetic was faster than that of multiplicative congruence arithmetic. The correlative value of random series almost was zero.(3) Regarding not harm the images quality as the premise, the speed of FM screening was heightened.

主要结论：利用所建立的条件半色调函数进行图像加网，操作简单、控制精确，使发生阶调不连续处的密度差平均减少到0.01275，明显改善了调幅加网印品的质量；(2)无理数取尾法产生随机数的速度快，数列间几乎没有相关性；(3)在不损失图像质量的前提下，提高了调频加网的输出速度。

The main research methods are:(1)Theory analysis:from the 2D plane geometry analysis, dots continuity characteristics are found. The first time irrational fraction algorithm is used in FM program.(2)Experiments reaearch:experiments of condition halftone function are designed under the cross-experiment principles. The first time variable information printer and C# language are used in experiment.(3)Data processing:new type digital density apparatus is used to measure data. Compare is used in processing data and error cause are explained. The main works as follows:The dot area percentage has been gained and new condition halftone function has been set up.(2)After being corrected, speed of irrational fraction algorithm has been compared with multiplicative congruence algorithm's.

本文的主要研究方法有：(1)理论分析：运用数字加网原理，从二维平面几何分析入手，借助实验验证研究网点连续特性；首次系统地把无理数取尾法随机数生成器引入到调频加网系统中，根据实验修正生成器的模型，运用统计假设检验理论，对生成的随机数序列进行统计假设检验；(2)实验研究：根据正交实验法则设计实验，首次采用可变信息印刷机(HP Laser PS印刷机)输出实验样张，克服了用传统胶印机作实验影响因素多的缺陷；采用新型数字式密度仪测量密度值，提高了数据精度；采用最新编程语言编写调频加网程序；(3)数据处理与分析：利用平均值比较法处理数据，对误差产生的原因进行讨论。

The music in the library is first passed through the similarity algorithms, which can be determined through a number of processes (MARSYAS, AFX and the Last.fm and Echonest APIs).

库中的音乐先通过相似性算法匹配，这种相似性算法的基准点基于一系列的外部数据处理（MARSYAS， AFX和Last.fm以及Echonest的API）得出。

Can you get the station on FM as well as on medium wave?

除中波外，你还可以收听调频台吗？

According to early FCC documents from 1945 and 1946,"The three major factors which the Commission considered in its decision to place FM in the 88-108 megacycle band were (1) sporadic E interference,(2) F2 layer interference, and (3) extent of coverage."

根据早期的FCC 文件从1945 年和1946 年，"委员会考虑在它的决定安置FM 在88-108 兆赫带的三个主要因素是(1)分散E 干涉，(2) F2 层数干涉，和(3)程度覆盖面。"

Commercial FM broadcast in g stations transmit their signals in the frequency range of 88 megahertz to 108 MHz.
