是关于消防车的警报灯的
2.1 Visual warnings
Visual warnings on a fire appliance can be of two types:either passive or active.
2.1视觉警报 消防车上的视觉警报,可以分为两种类型：
2.1.1Passive visual warnings
The passive visual warnings involve the use of high contrast patterns.Older vehicles (and those in developing countries) are more likely to have their patterns painted on,whereas modern appliances often carry retro-reflective designs which reflect light from headlights or torches.Patterns include "checker board" (alternate coloured squares,sometimes called "battenburg markings",named after a type of cake),chevrons (arrowheads,often pointed towards the front of the vehicle if on the side,or pointing vertically upwards if on the rear) or stripes (along the side; these were the first type of retro-reflective devices introduced,as the original retro-reflective material came only in tape form).In some countries,in addition to retro-reflective markings,vehicles are now painted a bright yellow or orange,although in many other countries,red remains the colour for fire engines.In Australia a number of rural fire units are painted white,such as those used by the Country Fire Service in South Australia,making them more visible in bushfire conditions.

Answer 1

Visual warnings on a fire appliance can be of two types:either passive or active.
2.1视觉警告 消防车上的视觉警告,可以分为两种类型：被动型或者主动型.
涉及被动视觉警告高对比度模式的使用.在发展中国家中的旧车,一般会使用反光设计方案的头灯或电筒光.比如“棋盘”（候补颜色方块,有时也被称为“巴滕堡标记”或者V形箭头（经常对车辆的前面,如果在一侧,或上垂直向上指向指出,如果后面）或条纹（沿一侧;这些人的反光装置推出第一种类型,与原来的反光材料只有在磁带的形式来）.在一些国家中,除了反光标识,车辆现在画了一个明亮的黄色或橙色,尽管在许多其他国家,红色仍然是消防车的颜色.在澳大利亚,农村消防车都会被漆成白色,比如由国家消防局在南澳大利亚使用的车辆,这样使得他们在林火状况中更容易被人看见.
