被测试的是典型台漂——“小鱼儿”5号(为使测试准确应事先将被测试浮漂在水中浸泡数小时)在一个容器内注水,使水深大于漂长即可。笔者用的是2000毫升玻璃量筒。另备少许铅皮和直径为0.14毫米,长度为80毫米的铜丝七根,每根铜丝约重10毫克。如图表示测试的全过程。 1.将铅皮紧缠在浮漂下部,调整其重量,达到图中最右边的状态。即正好使全部漂杆露出水面。 2.将七根等长的铜丝再缠到浮漂下部,适当剪去两端(注意保持等长),达到图中最左边的状态,即漂杆
To be tested is a typical bench drift - “Little Fish” No. 5 (in order to make the test should be tested in advance soaked in water for several hours) in a container filled with water to make the water depth greater than the drift can be. I use the 2000 ml glass measuring cylinder. Another little lead and a diameter of 0.14 mm, a length of 80 millimeters seven copper, each weighing about 10 milligrams of copper. Figure shows the whole process of testing. 1. The lead wrap tight in the lower part of the float, adjust its weight, to the right of the state figure. That is, just put all the drift rod out of the water. 2. The seven equal length of copper wire and then wrapped around the lower part of the float, appropriate cut off both ends (pay attention to maintain the same length), to the leftmost state in the figure, that drift
