The controller makes the closed-loop systems internally stable and minimizes the H2 norm of the transfer matrix Tzw from w to z. Two Riccati formulae based on 8 operator is deduced. The H2 problems for continuous time systems, Z operator models and 8 operator models are investigated respectively.The guaranteed cost control problem of robust stabilization and robust performance for uncertain systems which is described by 8 operator is discussed in this paper.

Persistence of grazing mixed pasture has been a key issue in environment conservation and sustainable utilizing of resources in karst region. Under moderate grazing with Corriedale sheep, the productivity and botanical composition of Trifolium pratense mixtures were studied over a 20-year period in karst region of southwest China. Four mixtures consisted of Trifolium pr...

用考力代绵羊轮牧，在牧前和牧后草地现存量(干物质，DM，drymatter)分别为1800~2500(草层高15~18cm)和900~1200kg·hm-2(草层高3~5cm)的适度放牧利用条件下，对亚热带最常见的豆科牧草红三叶与禾本科牧草的两两混播草地的群落生产力和持久性开展长期研究。20年的结果表明：适度放牧利用下，群落地上总生物量长期稳定，各组合间差异不显著，总盖度20a后仍高达97%以上；适度放牧有利于牧草的生产力持久性，红三叶、鸭茅、多年生黑麦草和黑穗画眉草都在群落中长期存在；群落净产量和持久性是尺度依赖的，群落长期净生产力以红三叶+鸭茅的最高(DM产量353.3g·m-2·a-1)(P.05)，对杂草侵入的抵抗力最强，而前10a红三叶+多年生黑麦草有很高的净生产力DM产量449.8g·m-2·a。。。

Doo-wop, droopy melodies and sighs and swoons also find their way into her songs.Never forgetting her classical lessons, Brooke says she strives to "connect the 'classical world' with the 'mainstream world' by showing people it all works hand-in-hand." Although they may be presented differently, she says:"The beauty in the structure of a Mozart piece is essentially the same structure used in pop songs"

Brooke Waggoner的魅力是发自于内心的，她试图把日常生活中的细节深刻化，锤炼出细小并打动人心的感情，并努力地将每一个音符都变成记忆，将每一分旋律都变成记录岁月流逝的诗歌，Brooke Waggoner用自己独到的音乐语言承载他内心最真诚，最纯真的自白，就像一根洁白的羽毛，在蔚蓝的天空下飘荡着寻找下一个着陆点。

For distorted book image under random twisted status,by comparing its margin-gray-curve data with the stored margin-gray-curves data,a group of multinomial coefficients whose corresponding twisted status is proximal to that of the to be corrected image can be selected out to determine automatically a group of distortion parameters that is suitable for distortion correction.

任意弯曲状态下的书籍扫描图像可以在数据文件中搜索到与其最接近的弯曲状态，并利用对应的多项式系数自动求得最佳畸变参数，用于图像的畸变校正实验，获得了较好的校正效果，最大误差由未校正时的63%下降到了4.4%。这使得在无需人工测量或调整畸变参数的条件下可自动校正书籍扫描图像。

This week IG Metall, the country's biggest trade union, confirmed its pay demand for the 12 months from April 1st: 6.5%, bitte, for 3.4m engineering and electrical workers, the union's boldest request for five years.

就在本周，德国最大的工会组织IG Metall证实：旗下340万工程和电力工人，从4月1号开始的下一年度的工资涨幅要求为6.5%。这是近五年以来，该工会涨幅要求最大的一年。

The inference in Credal network is the computation of tight lower and upper bounds for conditional probabilities.A new algorithm for inference in Credal networks is presented based on the framework of bucket elimination.The burden of computation is alleviated by enumerating some of values and the accurate result is obtained.

Credal网络的推理是计算一定证据下的后验概率最大值和最小值，给出了一种Credal网络推理的新方法，该方法是在桶消元框架下通过枚举计算部分因子函数值，使计算量大大减小，并且可以得到精确的结果。

This research take late-maturing variety adzuki bean Jihong-4 as the experiment material, After the photoperiod inducement at different leaf ages treatment, the result showed that the activity of NR under LF treatment is higher than CK treatment on the whole, and is lower than SD treatment; The content of the dissociation amino acid under these three treatments show a descend trend along with the leaf ages accretion, but the inducement increasing the content of dissociation amino acid, different leaf ages leaves show some difference, and alternating rise with SD treatment; Inducement can reduce the content of soluble sugar, and continuous inducement shows a accumulation effect; 2LF is the most sensitivity stage for soluble protein under photoperiodic inducement, From this stage, each leaf indumenta can reducing the content soluble protein, but continuous inducement reducing rising it.

本研究通过光周期诱导的方法，对中晚熟品种冀红4号红小豆进行不同叶龄进行处理，结果表明：所有叶龄处理下硝酸还原酶活性基本高于自然光处理而低于连续短日照处理下的；随着叶龄增大，各处理游离氨基酸总量均呈下降趋势，但光周期诱导可提高游离氨基酸含量，不同叶龄表现有所差异，与连续诱导交替上升；诱导可降低可溶性糖的含量，并连续诱导出现累积效应；2LF是光周期诱对可溶性蛋变化最敏感的时期，这个时期起单个叶龄诱导可降低可溶性蛋白含量，但连续诱导却可提高；LF处理下的类胡萝素总体含量高于另两个处理，而LF处理下的叶绿素含量在仅3叶龄前高于CK处理下的，随后出现下降趋势。

The camera can look straight down with no loss of coverage. It can operate in a wide range of lighting conditions with the 4-9 mm auto-iris varifocal lens. The line-lock and V-phase in 24-VAC mode allows for extra stability. The camera has 10 internal, adjustable DIP switches for maximum picture quality and a second video output for a test monitor.

该机向下扫描时不会漏掉监视范围。4-9mm的自动虹膜变焦镜头允许摄像机在各种光线下工作。24-VAC电源模式下的line-lock和V-phase更稳定。10个内置可调DIP开关使摄像机能拍出最清晰图片，第二次视频输出用于试用监测器。

In this view, a welfare policy designed to maintain a narrow gap between the best- and worst-paid employees has limited the earnings of the most skilled workers across all sectors, tempting many of them abroad.
