每年中秋节后两三天,我国钱塘江口的海潮,便会呈现它一年当中最为壮观的景象:潮头高达3~5米,挟卷10~20万吨海水,每秒钟推进的距离接近10米,犹如千军万马奔腾,发出巨大的声响。虽然秋潮较大在各地都是普遍现象,但能达到钱塘江这样规模的潮涌现象,在世界上却很少见。 Two or three days after the Mid-Autumn Festival each year, the tide of the Qiantang Estuary in our country presents the most spectacular spectacle of the year. The tidal head is as high as 3 to 5 meters and the volume of water is 10 to 200,000 tons, approaching the distance per second 10 meters, like a mighty force Pentium, issued a huge sound. Although the larger autumn tides are commonplace everywhere, it is rare in the world to achieve such a scale surge in the Qiantang River.
