nseg
NSEG是美国兰利研究中心推出的飞行器起飞、爬升、巡航、加速、下降、减速和着陆等各个过程分析软件。(NSEG was developed to perform rapid aircraft mission analyses. It is based upon the
use of approximate equations of motion whose form varies with the type of flight
segment. Flight segments considered are takeoff, accelerations, climbs, cruises, descents,
decelerations, and landings. Layered atmosphere options are available. The program can
also be used for flight envelope mapping. NSEG provides the capability to analyze
aircraft missions from low to hypersonic speeds. Realistic and detailed vehicle
characteristics are input to NSEG to permit accurate mission analysis. NSEG allows
engine scaling so as to fit the design under analysis. NSEG contains several approximate
flight path optimization capabilities based on Rutowski energy-like criteria for
considering minimum time or fuel flight segments and maximum range segments during
climb or descent. Takeoff and landing analysis is based on the Air Force Flight
Dynamics Laboratory DATCOM method of high lift aerodynamic modelling)

CKplayer 支持HTML5移动设备的视频播放器 v6.4
ckplayer是一款在网页上播放视频的免费播放器，主要以adobe的flash CS5开发，支持html5视频播放，可以在Ipad，Iphone等IOS平台上播放视频，ckplayer是一个前台程序，不涉及asp,php,jsp,.net等服务器端代码，也不涉及到对服务器的操作(即不需要写入权限)，所以不存在安全方面的问题。
使用注意：crossdomain.xml文件直接拷贝到网站根目录下，很重要，不然有时会导致有些浏览器不兼容。文件说明：
adjustment.fla 调整比例插件
mylogo.fla 官方的logo源文件
Preview.fla 视频预览源文件
related.fla 播放结束显示精彩视频的源文件
right.fla 右边开关灯的源文件
