第三组;测算及搜救
一图:手表辨位。
原文:
Watch Navigation
To navigate by watch in the Northern Hemisphere (right), point the hour hand at the sun and bisect the angle between it and 12 o'clock to find south. In the Southern Hemisphere (left), point the 12 o'clock mark at the sun and bisect the angle between the mark and hour hand to find north.
谷译:
身处北半球(右),指向太阳,时针和对开它与角12时找到南方。在南半球(左)在太阳,点和12点大关角平分标记和之间的时针找到北
二图:日影辨位。这个我也亲身进行过测试,对照指南针查看测试结果,很准地说。(详细步骤请参考本人的日影辨位法一贴)
原文:
Time and Navigation By Shadow
Time-elapse plotting using a shadow can help you ascertain direction (left) and time (right).
谷译:
时间流逝绘图用影子可以帮助你确定方向(左)和时间(右)。
三图:估计角
原文:
Estimating Angles
Estimating angles can be a useful skill for helping calculate distances and also for computing bearings. Some simple hand configurations, shown here, provide rough guidelines to useful angles. Note that every finger's width between sun and horizon
represents about 15 minutes of available sunlight.
Top left: 150 degrees
Top right: 120 degrees
Center left: 2 degrees
Center middle: 4 degrees
Center right: 6 degrees
谷译:
估计角度可以成为帮助计算距离有用的技巧和计算轴承也。一些简单的手
配置,如图所示,提供有用的指引,粗糙的角度。注意每个手指的宽度介于太阳与地平线
代表约15分钟可阳光。
左上:150度
右上:120度
中心左侧:2度
中心中:4度
右:6度
四图:地毯式搜索
原文:
Sweep Search
If you are lost in the wilderness, be aware of how search parties might be looking for you. They will generally use one of
the two techniques, the sweep search, shown here, or the square search (next slide). Helicopters will typically describe an
ever-widening circle out from your last-seen position. The sweep search involves multiple searchers spread out in a line, all
advancing at the same pace.
人译;
如果你在荒野迷失方向,一定要清楚人们是如何去搜救你的。他们一般会采用两种搜救方式中的一种,地毯式搜索,如此所示,或者是广域搜救。直升机驾驶员通常会在最后一次见到你的位置(地图上)描绘出一个不断扩大的圆圈出来。地毯式搜索包括在一条线上扩展出来的以同样的速度推进的多种搜索。
五图:广场式搜索
原文:
The square-search technique starts from a central position and then works outward systematically, turning at right angles and
progressively lengthening the distance of travel to methodically cover an area of ground.
人译:
这个广场搜索技术开始从中央位置,然后向外工程系统,转向成直角,并逐步延长旅行距离有条不紊地覆盖面积。
六图:信号线索
原文:
Marking a Trail
If you have to move from one position to another, leave trail signs to give search parties or other people information about
where you have gone, or to provide details about what lies ahead. Signals include, from top to bottom: “This is the road,”
“Turn left,” “Turn right,” and “Danger.”
谷译:
如果您必须从一个位置移动到另一个,留下线索的迹象,让搜救人员或其他人的信息
你走了,或提供有关的细节是什么样的未来。信号包括,由上到下:“这是道”“向左转”,“向右转”和“危险”。
