    • An apparatus is capable of restoring a clock of a second node in a communication system with a symmetric network construction of a first node that is capable of receiving a Global Positioning System (GPS) signal, and the second node that is not capable of receiving a GPS signal. The method includes identifying synchronization information received from the first node, determining a delay with the first node, generating a clock using the synchronization information and delay, removing a clock phase being out of a reference range in a phase identification interval, dividing the phase identification interval into at least two subdivision intervals, and removing a clock phase being out of a normal operation range of a phase in each subdivision interval.
    • 一种装置能够恢复具有能够接收全球定位系统(GPS)信号的第一节点的对称网络结构的通信系统中的第二节点的时钟,以及不能够接收 GPS信号。 该方法包括:识别从第一节点接收的同步信息,确定与第一节点的延迟,使用同步信息和延迟生成时钟,在相位识别间隔中移除时钟相位超出参考范围,将相位识别 间隔到至少两个细分间隔,并且去除在每个细分间隔中的相位的正常操作范围之外的时钟相位。

    • A flow control mechanism, for improving pressure resistance and hull vibration, includes a lower fin and an upper fin. The lower fin is disposed between a second station and a fourth station in a length direction of a ship and between 10% and 20% of a design draft from a bottom of the ship in a height direction of the ship, the lower fin being inclined at an angle of 20 to 40 degrees with respect to a design draught (or base) line. The upper fin is disposed between the second station and the fourth station in the length direction of the ship and between 30% and 60% of the design draft from the bottom of the ship in the height direction of the ship, the upper fin being inclined at an angle of 10 to 30 degrees with respect to the design draught (or base) line. Further, an additional fin is disposed between a first station and a third station in the length direction of the ship and between 5% and 20% of the design draft from the bottom of the ship in the height direction of the ship, the additional fin being inclined at an angle of 10 to 40 degrees with respect to the design draught (or base) line.
    • 用于改善耐压和船体振动的流量控制机构包括下翅片和上翅片。 下鳍在船的长度方向上设置在第二站和第四站之间,并且在船的高度方向上从船的底部设计为设计吃水的10%至20%,下翅倾斜 相对于设计吃水(或基)线为20至40度的角度。 上鳍在船的长度方向上位于第二站和第四站之间,并且在船的高度方向上从船底部的设计吃水深度的30%至60%之间,上鳍倾斜 相对于设计吃水(或基)线为10至30度的角度。 此外,在船的长度方向上在第一站和第三站之间设置附加的翅片,并且在船的高度方向上从船底部的设计吃水深度的5%至20%之间,附加翅片 相对于设计吃水(或基底)线倾斜10到40度的角度。
