2，苯甲醛山梨酸对羟基苯甲醛在应用方面的区别

这要取决于对羟基苯甲醛中的杂质，杂质不同，可能提纯除杂的方法不同。 除杂的原则： (1)不增：不增加新的杂质； (2)不减：被提纯的物质不能减少； (3)易分：操作简便，易于分离； 常见物质除杂总结 原物所含杂质除杂质试剂除杂质的方法 (1)N2
氨基酸（amino acid）既含氨基又含酸性基团的有机化合物。生物体中绝大多数是带羧基的氨基酸。α氨基酸是蛋白质的主要组分，是生物体中最重要的氨基酸。α-氨基酸的立体结构除甘氨酸外，α-氨基酸的α-碳原子上所连结的4个基团都不相同。

5，XML是用什么编程工具进行编程的

XML是eXtensible Markup Language的缩写，是一种简单的数据存储语言，使用一系列简单的标记描述数据，而这些标记可以用方便的方式建立，虽然XML占用的空间比二进制数据要占用更多的空间，但XML极其简单易于掌握和使用。 说白了它是一种数据库，而且是跨平台的得数据库。 使用XML的编程，几乎所有得程序都能用XML来编程。
文本编辑就可以了
都可以用XML来进行编程 ！XML只是把需要的信息保存下来，任何语言都能从XML把信息读出来。
记事本也可以的
XML文档是文本文件，任何一种纯文本文件编辑工具都可以用XML文档的编辑，如 记事本，XML Notepad,XMLSPY等。
推荐使用 xmlspy XMLSpy是所有XML编辑器中做得非常好的一个软件，支持WYSWYG。支持Unicode、多字符集，支持Well-formed和Validated两种类型的XML文档，支持NewsML等多种标准XML文档的所见即所得的编辑，同时提供了强有力的样式表设计。 本版增加了几个很有用的功能: XSLT 调试工具，XSL 也就是所谓的扩展风格表单语言（Extensible Stylesheet Language）由3种语言组成。这三种语言负责把XML文档转换为其他格式。XML FO （XSL格式化对象：XSL Formatting Objects）说明可视的文档格式化，而 Xpath 则访问XML文档的特定部分。而 XSLT（XSL Transformations）就是把某一XML文档转换为其他格式的实际语言。 更多情况， WSDL 编辑器， WSDL就是描述XML Web服务的标准XML格式，WSDL由Ariba、Intel、IBM和微软等开发商提出。它用一种和具体语言无关的抽象方式定义了给定Web服务收发的有关操作和消息。 Java / C++ 代码生成器，这个可以从 XML Schemas 文档中生成 Java/C++ 代码。 集成 Tamino， Tamino 产品是世界第一... 下载地址 http://www.skycn.com/soft/24224.html

not any more =as……意指两者情况一样。我转换一下句子，楼主应该比较容易理解：humans should not try to avoid stress any more than they would shun food ,love or exercise===humans should not try to avoid stress as they would not shun food ,love or exercise.这样明白了吗？希望能帮到你。(*^__^*)
