对于每一个人来说,“小人”都是一个极端的蔑称。所谓“两面三刀、阳奉阴违”,人人都敬而远之,古龙在其书中说到,他最痛恨的就是“嘴里叫哥哥,手里捅刀子”的家伙。猫王的一位朋友就曾有感而发:“千万不要轻信那些表面的现象,也不要被那些甜言蜜语所迷惑,不了解实际情况决不能轻易下手。那些奸商……”朋友很是愤怒,因为他受过骗。那年,他要买打印机,“就想买个耐用的,便宜点的。”于是,这老兄四处查找信息,终于在某杂志上找到他所中意的对象,便宜、耐用、不偏不倚。朋友打电话去询问,销售小姐很热情,各项情况娓娓道来,并保证广告所说一切属实,敬请现场查看。朋友一时喜不自禁,第二天就驱车前 相似文献

初遇Hero,是在I社区里,那时候自己刚到这家公司,对各种图片软件一窍不通,而主编交给我的一大堆任务全跟那些PHOTOSHOP,DREAMWEAVER什么的有关,我看着它们,这里改改,那里改改,都不得要领,简直被他们弄得焦头烂额了。于是百无聊赖之际,走走停停地就来到I社区,开始以为这不过是个供人扯淡的茶庄,谁知才说了一两句话就发现这里高手如 相似文献

夏天的天气简直熱得都快要赶上e浪潮了,让e诸葛实在有点不受用。于是乎,e诸葛抽了个空到大商场去查探了一番。虽然这不是一个大老爷们愿意干的事,但是既然是“微服私访”,就有几个原因:一是想吹吹空调,吸吸凉气,驱走烦躁;二是想在商场中找寻一些关于传统零售业迟迟不肯进入电子商务的蛛丝马迹。走了走大商场.他好象明白了其中一二。都说“购物是一种享受”,大概只有抱着研究的心态,e诸葛才注意到:商场中不但有凉爽的环境、柔和的灯光、优美的音乐,就连货物的摆放、位置也有讲究。似乎大型商场一层总是化妆品和首饰,二、三层铁定是男装女装,超市嘛,肯定在地下……这就是传统商家的一些经验吧。有层次感、丰富多样的物品加上员工的服务态度……加在一起 相似文献

针对约束二维矩形剪切排样问题,提出了一种基于束搜索的三阶段剪切排样算法。其切割过程包括三个阶段:板材剪切成段,段剪切成条带,条带切割成准确尺寸毛坯。采用动态规划确定段的价值,复杂度低的拼接递推不同长度子板的初始价值和板材的初始可行解,束搜索优化板材的排样方式。束搜索的节点用矩形对表示,分别是段组合而成的局部方式和未填充的剩余子板。以局部方式价值与剩余子板的初始价值之和作为节点的估计值。按估计值选择精英节点继续分支,其他节点直接删除不再回溯。实验结果表明该算法可缩短三阶段同质排样的计算时间,且所获得的余料大,利于余料的回收管理和再利用。 相似文献

We consider a loss model of an unbuffered resource having C channels, which are shared by several different types of service connections. Connections of each type arrive in a Poisson stream and request a number of channels, which depends on the type. An arriving connection is blocked and lost if there are not enough free channels. Otherwise, the channels are held for the duration of the connection, and the holding period is generally distributed. It is assumed that C and the traffic intensities are proportionately large. The admission control problem is considered for specified upper bounds on the blocking probabilities, and the boundary of the admissible set is investigated asymptotically. Characterization of admissible sets is extremely useful, not only for connection-level admission control, which is the context in which this topic has typically been considered in the past, but also for higher level objectives, such as network economics, network design, and network control. The asymptotic view of the admissible set is particularly appropriate for the higher level objectives, where the fine details are not as important as the qualitative properties of the shape of the set and tractability of the numerical calculations for large systems. Our results are derived by investigating the local behavior with respect to the tangent hyperplane at a point on the boundary of the admissible set. The lowest order results that hold in the asymptotic limit C→∞ are given first. Importantly, the boundary is linear for the key critically loaded and also for the overloaded regimes, and weakly convex for the underloaded regime. Next, refined results that hold for C1 are given, which indicate that the boundary is not convex, although only slightly so. 相似文献

采用离散变分局域密度泛函(DVLDF)方法及团簇模型研究了IIVI族半导体中的掺杂及补偿问题。研究了ZnSe中的N,P,As,F,Cl,Br等杂质不同的结构和电子性质。发现NSe在ZnSe中没有JahnTeler形变,而PSe和AsSe存在这一形变,从而判定N是其中最有效的p型掺杂剂。对于n型的ZnSe,研究发现Cl是最有效的施主杂质。根据对缺陷复合体的计算,发现NSeZnVSe及诸如NSeZnint的多N集团对于p型ZnSe的补偿有着重要作用。研究表明,对于ZnTe来说,Cl不是有效的施主杂质,而N是有效的受主杂质。 相似文献

Representation and processing of XML data in Scheme are considered. Scheme is a functional programming language belonging to the LISP family. The SXML specification is discussed, which defines methods for representing XML data in the form of S-expressions in Scheme. Possibilities of extending this specification are considered. Methods of parsing and representing XML data are analyzed, possibilities of applying Scheme to the development of XML applications are discussed, and a survey of the relevant literature is given. Functional methods for processing semistructured data are discussed, and examples of using Scheme for processing SXML data are given. Methods for extracting a schema of semistructured data (DataGuide) and application of those methods are considered, and functional algorithms for the construction of DataGuide are proposed. 相似文献

A quantitative method for geologic correlation of two electric-log sequences of unequal length is proposed which calculates scaling factors that are applied to Fourier transformations of each time series. Correlations thus are made in the frequency domain and are based on an assumed recognizable, unique periodicity in correlative geologic units. A FORTRAN IV program is presented and application is demonstrated for two wells in Texas. The method is useful for stratigraphic correlations that are to be performed by automated procedures and which may not be visually obvious. 相似文献
