结构图中字体标注样式有何规定

Posted 2023-05-15

符号的印刷和书写字体应符合下列要求：

1 主体符号的字母必须采用斜体。

2 上、下标的字母、数字或标记，除代表序数的字母（i，j，m，n）应采用斜体外，均应采用正体。

3. 单个拉丁字母ο不应作为主体符号和下标，避免与数字“零”相混淆。小写希腊字母ι、ο、υ、κ、χ不宜作为主体符号和上、下标，避免与小写拉丁字母相混淆。以小写拉丁字母l作下标，在印刷时可用大写拉丁字母L代替，避免与数字“1”相混淆。

4.图纸上所需书写的文字、数字或符号等，均应笔画清晰、字体端正、排列整齐；标点符号应清楚正确。
文字的字高，应从如下系列中选用:3.5、5、7、10、14、20mm。如需书写更大的字，其高度应按 的比值递增。
图样及说明中的汉字,宜采用长仿宋体，宽度与高度的关系应符合规定。大标题、图册封面、地形图等的汉字，也可书写成其他字体，但应易于辨认。数字和字母采用直体，便于使用绘图工具。 例如：图名、设计说明、图形符号等所用的汉字，可视为不同用途的汉字，其大小可以不同；同一套图中各图名可视为同一用途的汉字，其大小宜相同。

常用CSS font属性连写

连写顺序：

font-style font-variant font-weight font-size/line-height font-family

font-style 规定字体样式

normal  默认值。浏览器显示一个标准的字
italic 浏览器会显示一个斜体的字体样式
oblique  浏览器会显示一个倾斜的字体样式
inherit  规定应该从父元素继承字体样式

font-variant  规定字体异体。

 

normal  默认值。浏览器会显示一个标准的字体。
small-caps 浏览器会显示小型大写字母的字体。
inherit  规定应该从父元素继承 font-variant 属性的值。

font-weight 规定字体粗细。

normal  默认值。定义标准的字符。
bold 定义粗体字符。
bolder 定义更粗的字符。
lighter  定义更细的字符。
100~900
定义由细到粗的字符。400 等同于 normal
inherit  规定应该从父元素继承字体的粗细。

 font-size 规定字体大小

/* <absolute-size>，绝对大小值 */
font-size: xx-small;
font-size: x-small;
font-size: small;
font-size: medium;
font-size: large;
font-size: x-large;
font-size: xx-large;
 
/* <relative-size>，相对大小值 */
font-size: larger;
font-size: smaller;
 
/* <length>，长度值 */
font-size: 12px;
font-size: 0.8em;
 
/* <percentage>，百分比值 */
font-size: 80%;
 
font-size: inherit;

line-height 规定行高

//normal  默认。设置合理的行间距。
//number 设置数字，此数字会与当前的字体尺寸相乘来设置行间距。
//length 设置固定的行间距。
//%  基于当前字体尺寸的百分比行间距。
//inherit  规定应该从父元素继承 line-height 属性的值。

 font-family

family-name generic-family	用于某个元素的字体族名称或/及类族名称的一个优先表。 默认值：取决于浏览器。
inherit	规定应该从父元素继承字体系列。
