影响钩线强力的主要因素是什么？约线受损到什么程度就必须要放弃？放长线约大鱼有没有科学道理？影响钓线强力的因素很多，受拉力伸长过度、摩擦、挤压变形这三种常见现象，都会使钓线的内部结构发生变化，产生“内伤”，致使钓线的抗拉强度降低。另外，垂钓中钓线还时时受到 What is the main factor that affects the strength of the hook? Coincidence to what extent have to give up? Put a long line of big fish there is no scientific truth? Affect the fishing line strength of many factors, due to excessive elongation, friction, extrusion deformation of these three common phenomena, will change the internal structure of the fishline, resulting in “internal injuries”, resulting in lower tensile strength of fishline. In addition, the fishing line is also from time to time
