简介：低矮、修长及沉厚．正好用来形容新一代的2004年版本田Shadow750。自1997年面世以来一直配用一台水冷V型双缸发动机，在可靠性方面毋庸置疑．这也是本田十分倚重的一台动力装置．它的优势在于动力充沛及输出均匀。在新款Shadow750上本田不单将造型更新．更把发动机的性能进一步改良。

简介：中国从严肃的水问题正在经历。在在堤的构造的中国的九主要的河盆之中有许多差别，水库，制约，洪水分泌物工程，洪水转向工程，浇生态的建设，水管理管理，等等。为九条主要的河的水资源的阴影价格能提供建议给中国政府。这篇文章开发价格基于优化模型的amultiperiod输入产量接近的一个动态阴影。不同于以前的途径，新模型基于动态可计算出来的一般平衡(DCGE)解决水资源的边缘的long-termprices的问题的模型。首先，DCGE的定义和算法被详细描述。第二，为在在用国家的水管理input-holding-output的中国的1949-2050的九条主要的河的水资源的阴影价格的结果搁置因为在1999的九条主要的河被列出。这篇文章的Aconclusion是为九条主要的河的水资源的阴影价格大部分基于缺乏的程度。水资源的售价应该经由代表阴影价格的参数的用法被修订。

简介：摘要：本文对linux系统shadow文件SHA512模式下密码的生成方式进行了详细的讨论，同时对密码学安全进行了简要介绍。

简介：前言：本文讲述了“TrapezoidalShadowMaps”技术在实现大范围的实时动态阴影中的应用和一些使用细节，这需要读者对“ShadowMap”技术有较透彻的理解并对3D数学有一些基本了解。
