  新华社“雪龙2”号11月27日电(记者刘诗平)中国首艘自主建造的极地科学考察破冰船“雪龙2”号26日完成首向和尾向破冰试验。 破冰试验在中山站附近的普里兹湾海域进行,从北京时间16时52分开始,持续约3.5小时。破冰试验是为验证这艘新破冰船是否达到设计指标,并帮助驾驶人员掌握“雪龙2”号在破冰时的各种操纵特性。 按照设计指标,“雪龙2”号能在1.5米厚度冰加上0.2米厚度雪的情况下,以2至3节航速(1节约合每小时1.852公里)连续破冰行驶。 测试人员所取样品显示测试时冰厚约1.4米、雪厚0.3至0.4米,冰强超过700千帕。 此前3天,“雪龙2”号已完成中山站附近的航道破冰,为“雪龙”号海冰卸货开辟了一段约14海里(约合26公里)的冰上航道。 “雪龙2”号于10月15日从深圳启航首航南极,与“雪龙”号一起展开“双龙探极”。完成中山站作业任务后,“雪龙2”号将前往南大洋宇航员海进行综合科学考察。
