不可实施的

Under no circumstances use a candle which has already adorned a dinner table or been used as a bedroom candle or night-light. There is a very good occult reason for not using anything but virgin materials in magic. Vibrations picked up by secondhand materials or equipment may disturb your workings and negate their effectiveness.

用于点缀餐桌，卧室或夜晚照明之类的旧蜡烛，无论如何都不可用于实施魔法，因为旧的材料或仪器里的能量也许或扰乱你的工作，并消除魔法的效力，这个极好的神秘的理由将使你只用新材料。

The design includes many new technologies in data exchange and data security, they are: Converting non-XML data to XML in order to apply the XML security technology to more data types; Using the technology of XKMS and PKI to manage the public key in order to overcome the shortage of complexity and difficulty in using PKI and improve the efficiency of the public key management; Using Diffe-Hellman algorithm combining with the public key technology to exchange secret key in order to furthest increase the security of the key; Using the technology of XML digital signature algorithm to ensure the integrity, message authentication and signer authentication of the data; Using the technology of XML encryption to ensure confidentiality of the data; Defining delegable access rules on the structure and content of the XML documents to provide fine-grained access control. According to the XML security framework, a XML security library is designed and implemented.

在对XML及其安全技术主要包括XML加密技术、XML数字签名、公钥管理、密钥产生和交换进行研究的基础上，结合传统密码技术和XML安全技术提出了一种基于XML的数据安全模型，模型中包含了目前网络数据交换和安全领域的一系列最新技术，主要有：将非XML格式数据转换为XML格式数据的方法，以保证现有的大部分网络数据能够应用XML安全技术；使用XML公钥管理技术结合PKI技术管理公钥，以克服PKI技术实施和部署复杂、难度大等问题，提高公钥管理的效率；使用Diffie-Hellman算法结合公钥技术交换密钥，以最大限度保证密钥的安全；使用XML数字签名技术保证数据的完整性、不可否认性和发送方身份认证；使用XML加密技术保证数据的机密性；根据XML文档的内容和结构定义授权访问规则进行良好的访问控制。

The traditional DEA model can not beused to deal with such stagewise operation problems. In order to avoid the limitation of the traditional DEA model, a multi-stage DEA model was set up based onthe idea of the DEA model with uncontrollable factor. Simultaneously, considering the shortage of the single DEA model, the multi-stage DEA model was extended to be the multi-objective one.

工程项目某一分期实施阶段的无效率可能导致整体计划的无效，为了克服传统DEA模型评价这类阶段性问题的局限，及时发现并调整工程项目的无效阶段，借鉴具有不可控要素DEA模型的思想建立了多阶段DEA模型，同时考虑到单目标DEA模型的不足，进一步将多阶段DEA模型扩展为多目标模型。

The article takes S Company as an example, briefly introduces the ERP risks identification, such as environment risk, technique risk, item advancing risk and management transforming risk before the enterprise carrying it out, and the risk management to handpicking raw and processed materials provider, cautiously choosing ERP system provider, avoiding hardware and secure technique risk, evading item advance risk, actively boosting operation flow reform etc.

本文以S公司为例，重点介绍了该企业在实施ERP项目之前对环境风险、技术风险、项目推进风险、管理变革风险等的识别，以及在精选原材料供应商、慎重选择ERP系统供应商、有效避免硬件和安全技术风险、规避项目推进风险和积极推行业务流程再造等方面采取的风险管理措施，并针对目前该公司ERP项目的缺陷提出了今后在避免&小会计&风险、不可扩展性风险和人才流失风险上面的具体防范措施。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
