简单几步让网站兼容IE10
简单几步让网站兼容IE10解决CSS 兼容性问题如果你经常使用CSS3 实现一些炫酷的效果，比如使用transition 实现让一个div 慢慢变宽的动效，你一定会为了兼容各个高级浏览器而这样写你的CSS 代码：1#box {2width: 200 px;3height: 200 px;4-moz-transition: al l2s ease 0s;5-webkit-transition: all 2s ease 0s;6-o-transition: all 2s ease 0s;7}8#box:hover {9width: 800 px;10}在Internet Explorer 10 上你也可以使用CSS3 实现这个效果了，只需要为#box 添加一行代码：-ms-transition: all 2s ease 0s;下面列举出几个典型的需要兼容Internet Explorer 10 的CSS3 特性：1. 3D 转换Internet Explorer 10 和Windows 8 中使用JavaScript 的Modern UI 风格的应用引入了对CSS3 3D 转换的支持。
Internet Explorer 9 增加了对CSS3 2D 转换的支持，使用JavaScript 的Modern UI 风格的应用也同样支持它们。
转换支持包括变换、旋转以及2D 和3D 空间中的元素拉伸，这些转换无需插件。
为了实现CSS 转换，需要使用-ms-transform 属性定义一个或多个转换函数。
例如，以下代码段是一个选择器，它将一个2D 偏移函数和一个3D 旋转函数同时应用于一个div 元素。
11div {12...13-ms-transform: skew(-45deg, 15deg) rotate3d(0.7, 0.8, 0.4, 55deg);14}这将得到以下图像：关于CSS3 3D 转换、转换函数以及如何实现它们的更多信息，请参阅：“3-D 转换”（/fwlink/p/?LinkId=238295）。

1. Information system
The information system is microprocessor based and reports on all aspects of burner control box operation and flame supervision. It informs continuously about the actual programming sequence the unit is just performing. Besides monitoring of the programming sequence it also allows to identify errors during start-up of operation without any additional testing devices. The automatically performed diagnosis is a valuable tool which facilitates service/ maintenance work and therefore saves costs. The analyses of the error cause can be done directly on stage or if not possible afterwards as the lock out reason is stored in a nonvolatile lock out mode memory. The information system communicates with the outside world using a LED (the used Flash-Code is similar to the Morse-Code). The messages are optically transmitted by a appropriately flashing LED. Using an additional terminal (optional), the messages can be recorded and displayed in easy readable form.

环境因素、危险源识别方法
环境因素、危险源识别评价方法一、环境因素辨识方法准备和保存有关的信息（如: 环评报告，厂区平面图，工艺物料流程图和/或工艺流程图，水流管线图等），使用这些信息(用图解法或其它方法)把组织细分成若干部分的活动、工艺、产品和服务。
有关的信息也包括历次环境管理体系运行和评审的反馈。
ⅰ、识别工厂的常规活动和服务（例如：废水处理，绿化服务和垃圾清运等）。
ⅱ、根据上汽依维柯红岩商用车适用的法律法规和其它要求,使用专业的评判,识别出在每个区域与重要的活动,产品和服务有关的环境因素，并识别出其潜在的环境影响。
A、系统地分析每个区域,根据每个常规环境因素类别(罗列如下)，排列出识别出的特定的环境因素(如:稀释剂挥发是属于大气排放一类的特定的环境因素)。
常规环境因素类别:区域输入:•水的使用•能源的使用•原材料的使用区域输出:•水体排放•大气排放•固体或液体废物和副产品•气味或噪音•能量释放B、考虑在正常作业情况,异常情况和潜在紧急情况下及新的开发、新的或更改的活动中的环境因素.C、识别可能的环境影响.ⅲ、评估这些因素以决定那些对环境具能或可能具有重大影响的因素.A、环境因素所导致的环境影响将根据严重度、发生率和可探测度的情况予以评估。
注：严重度、发生率和可探测度的情况将根据附录1 - 影响评分表和附录2－影响评分明细表予以评分。
B、使用专业的评判对每个识别出的环境因素，根据严重度，发生率和可探测度给予1-10围的评分。
C、每个环境因素的各影响评分值相乘得到风险值（1-1000）。
D、风险值大于或等于180的环境因素被确定为重大环境因素。
如果环境因素的严重度分值大于或等于9，其也同样被确定为重大环境因素.E、如果没有风险值大于或等于180的环境因素，则具有最高风险值的因素即为重大环境因素。
如果没有严重度大于或等于8的环境因素，则具有最高严重度值的因素为重大环境因素。
ⅳ、记录附录1----影响评分表附录2----影响评分明细表附录3----环境因素—主要活动,工艺,产品和服务及环境因素表·Word文档二、危险源辨识和评价方法风险评价的任务是评价识别出危害的风险程度，确定不可容许的风险，并给出优先顺序的排列。

only on three numbers, Cr, Cg, Cb, rather than the complete light spectrum.
