垂钓活动,试水极为重要。所谓试水,内容有二:一测比重,二测水深。通过两测,求其各自和两者间相适应。 测比重,是测定坠力与浮力之比,即钓钩、钓饵、连结件、钓坠等总重与所选用浮漂排水量重之比。 测水深,是测定钓域水的深度与钓线中的水线(含脑线及浮漂沉没段,下同)长度之比。 Fishing activities, test the water is extremely important. The so-called test water, there are two: one test weight, two measured depth. Through two tests, seek their own and between the two adapt. Measuring gravity, is to determine the ratio of buoyancy and buoyancy, that is hooks, bait, links, fishing and other float weight and the total weight of the selected floating ratio. Measuring water depth is the determination of the depth of fishing water and fishline in the waterline (including the brain line and the sinking sank, the same below) the length ratio.
