为更好地为厂矿化验室和有关单位技术人员提供切实的帮助,为其提供有关理化检测的 基础知识与方法,在化学工业出版社领导和责任编辑的大力支持下,编者对原《工厂分析化 学手册》第一版(1982年)和第二版(1992年修订本)再次进行了编写及修订。 本次编写及修订在保持原手册第一版和修订本主要特色的基础上,对有关章节及附录进 行了调整更新。本着湿法分析是基础,仪器分析是方向的原则,适当增加了一些章节。本手 册中内容全部采用法定计量单位

立体化学主要研究分子的立体结构（三维空间结构）及其立体结构对其物理性质及化学性质的影响。 立体异构是指具有相同的分子式、相同的原子连接顺序，不同的空间排列方式引起的异构。 立体异构包括顺反异构、对映异构、构象异构。 本章主要讨论对映异构. 4.1 手性和对映体 4.2 物质的旋光性和比旋光度 4.3 含有一个手性碳原子的化合物的对映异构 4.4 构型的表示法,构型的确定和构型的标记 4.5 含有多个手性碳原子化合物的对映异构 4.6 环状化合物的立体异构 4.7 不含手性碳原子化合物的对映异构 4.8 有机反应中的对映异构现象 4.9 外消旋体的拆分——将外消旋体分离成旋光体

一、被审计单位的财务造假及相关法律制度不健全 大量的审计失败案例表明,被审计单位的财务造假是审计失败的最根本原 因。近年来,资本市场存在太多的虚假和欺诈、甚至造假成风。2001年10月 19日的中国证券报公布了近年来影响重大的十大财务造假案。其中一些案例中 财务造假手段具有手续齐全、名目繁多、手段诡秘等特点。如:黎明股份的造 假手段主要是其所属的黎明毛纺织厂利用增值税抵扣制度通过与11家企业对开 增值税发票虚增收入和利润、其所属的营销中心向虚拟的销售对象虚开产品销 售发票虚增收入和利润、利用有关的出口货物优惠政策虚拟外销业务虚增收入 等;琼民源公司的造假手段主要是将合作方香港冠联置业公司投入的股本及合 作建房资金确认为收入,通过三次循环转账方法将虚构收到转让北京民源大厦 部分开发权和商场经营权的款项确认为收入,将收到民源大厦的建设补偿费作 为收入确认等

The true language of computers is a stream of 1s and 0s—bits. Everything in the computer, be it numbers or text or program, spreadsheet or database or 3-D rendering, is nothing but an array of bits. The meaning of the bits is in the “eye of the beholder”; it is determined entirely by context. Bits are not a useful medium for human consumption. Instead, we insist that what we read be formatted spatially and presented

devices the techniques were tailored to gate networks of the type described above. The term gate was already in use in the forties to denote the logical elements discussed earlier. There are very many good references on Boolean algebra and we may quote only a selected few of them. Suffice it to mention the texts by Hill and Peterson [1974], Kohavi [1978], and Hohn [1966]. These books give
