Under many conditions, as verified from outcrop data, fracture length is theoretically expected to follow an exponential distribution. 根据许多条件，并验证了从野外露头资料，断裂长度理论的预想为后续指数分布。
By improving the equipment and processing of spinning with the imported dew retting linen, then enhance the breaking elongated index of resultant yarn. 通过对进口雨露麻纺纱设备及纺纱工艺的改进，提高了成纱的断裂长度指标。
