日本沿岸漁业的漁船正以相当速度进行机器动力化,从表1所示历年变化,已甚明显;再者,这种漁船的机器动力化的实际情况是高压柴油机化,見图1及表4,也就很明显。 Fishing vessels on the coast of Japan’s fishing industry are being machine-motorized at considerable speeds. It has become obvious from the changes shown in Table 1 over the years. In addition, the actual situation of motorization of such fishing boats is high-pressure diesel engineization. See Figure 1 and Table 4. It is also obvious.
