According to common multimedia earners in the internet , the static images are selected as stego carriers . at first , beginning with typical method in special domain lsb ( least significant bit ) , the relative tests are developed , and the reasonable results are obtained 考虑到网络上最常用的多媒体载体，我们选取静态图像作为信息隐藏的载体，从空域中的典型算法? ?最不重要位( lsb )方法入手，开展相关的试验工作并得一些重要结果。
Abstract : this paper introduced the induction hardening experiment of components ? the gear - park and the drive support sprocket . give some advise on the pearlitic malleable iron ' s induction heat - treatment , and show coil design intending to meet the harden profilc according to the drawing 文摘:本文介绍变速箱零件? ?驻车齿轮和链轮支架的感应淬火试验工作，提出对可锻铸铁感应淬火中值得注意的问题及针对这两种零件的特殊硬化层要求而设计的感应器。
Taking bench shooting of the shuibuya yihongbao project as example , it makes use of the digital television system of drilling overall - hole wall to actually measure , the testing result of lateral fractural range is 4 - 5m , and that of bottom fractural range is about 3m 本文试验工作是以水布垭溢洪道工程梯段爆破为实例，采用钻孔全孔壁数字电视系统对混装乳化炸药爆破破裂范围进行了实际测试，测试结果为：侧向破裂范围为4 5m ，底部破裂范围值为3m 。
The china helicopter research and development institute is the only professional scientific research organization for helicopters design , research and experiment . it is the leader of the chinas helicopter development in this industry . the xbrothers security and facility control system has been applied in its computer room 中国直升机设计研究所是我国唯一一家专门从事直升机设计研究试验工作的综合性大型科研单位，在新型号和改进改型设计新技术攻关先进技术预研项目中，充当着中国直升机工业阵营中的“革命军中马前卒” 。
As to the work about experiment study , at first , the paper makes certain the prominent affecting factors to the automating and humidifying property of this kind of nozzle by orthogonal experiment . by jicha analysis method and fangcha analysis method , the paper got that the nozzle aperture , the initial water temperature and the spraying pressure have prominent effect to the humidifying property while the effect of the original air state is small 试验工作方面，首先通过正交试验确定对撞针型高压小孔径离心式喷嘴雾化加湿性能影响显著的因素，运用极差分析法和方差分析法，得到喷嘴孔径、喷水初温和喷水压力对喷嘴的加湿性能影响显著，而待加湿空气初状态的影响相对较小。
This dissertation focused on the research and experiment work in the following aspects : 1 ) the basic problems of digital 3d terrain modeling and visualization ; 2 ) the reconstruction of terrain surface ; 3 ) the real tune terrain simplifying and multi - resolution terrain model presenting . a view dependent dynamic multi - resolution terrain model is presented 论文从三维数字地形建模与可视化的基本问题，数字地形三维模型的计算机重构，复杂地形模型的实时动态简化与多分辨率表示等方面开展了研究与试验工作。
