I decided on a fairly fast shutter speed to capture the splashing waves while still blurring the water a little.

我决定使用相对快的快门速度来捕捉溅起的浪花，但还是造成了一点模糊效果。

The roll decay test in still water and roll tests in regular waves at zero speed on model of a deep-Vee planing craft are conducted, and problems arising from the data processing are discussed.

对深V型滑行艇模型进行了静水横摇衰减实验和零速正横浪规则波中横摇运动实验，讨论了在处理试验数据时所面临的一些问题；
