简介：季节的垂直侧面结盟变化压力，温度，水汽，和踪迹气体(O_3，N_2O，公司，CH_4)，在东亚区域上代表大气的条件直到100km的高度(30°-50°N，110°-150°E)被使用各种各样的观察数据，大气的热力学的参数的模型产量，和气体的集中构造。获得的东亚参考气氛的光特征与从典型中间的纬度夏天和冬季气氛的那些相比。在水汽地里，在夏天期间二模型气氛之间有主要差别，这被注意。结果的影响在在表面的到来的太阳的流动和在空气的顶的射出的陆上的流动上的水汽差别的夏天期间是14.3Wm~(-2)和6.5Wm~(-2),分别地。在另一方面，东方亚洲、中间的纬度气氛之间的冬季差别看起来不足道。为春天和秋天的参考气氛也是可得到的。利用是的构造大气的侧面输入到放射的转移模型，构造季节结盟气氛能更好便于的变化引用，这被期望对在东亚的光性质的描述。

简介：当数字地为一艘轮船建模时，参数评价的精确性是批评的。有限制的一个参数评价方法被开发，基于变化方法。在变化方法的性能函数和限制方程被分析系统的输入和输出方程构造。参数评价的问题被转变成最少的广场评价的一个问题。参数评价方程被分析以便基于Lagrange增加操作员得到参数的一个优化评价。模拟结果证明这个方法比传统的最少的广场评价好，当识别参数时，生产更高的精确。它在象系统鉴定和参数评价那样的申请的区域有很重要的实际价值。关键词最少的广场评价-参数评价-变化方法-限制基础条款：不到资助号码2009由海军设备部门基础支持了(189)。我皮脂腺囊瘤史在1982出生了。他是在海军海底的学院的一个讲师，中国。他的当前的研究兴趣是海底的航行。
