一艘渔船在航行中遇险,发出警报,在遇险地点西南10海里处有一艘货轮,接收到报时,发现遇险渔船正以9海里/小时的速度与沿南偏东75°方向向某小岛靠近,如果要在40分内将这艘渔船救出,求货轮航行的方向和速度.
下列各句中划横线成语使用恰当的一项是( )A.上海的娱记几乎倾巢出动,其他省市的也一大早就纷纷来到新闻发布会现场等候。B.海淀区十一学校甘兰佑老师面对生活中的变故安之若素,依然坚守三尺讲台。C.清华大学水利工程学院的师生们在一次野外勘察中,意外发现了一片原始喀斯特岩溶地貌,那些岩石形态优美,真是巧夺天工。D.“秦晋之好”这个成语是说春秋时期的秦、晋两个国家之间几代都有婚姻关系,可谓是间不容发。
1995年8月,当“亚洲通信卫星2号”升空不久,突然发生爆炸,而这场灾难的元凶是由太阳活动引发的高空切变风,这是由空间天气突变而引发的灾难。空间环境中,有时呈现这种情景——太阳上的太阳风、磁层、电离层和热层中可影响空间和地面技术系统的运行和可靠性以及危及人类健康和生命的状态。科学研究表明,太阳是一个能量输出不断变化的天体,正是这些变化,才引起了高层大气和电离层状态的强烈扰动。同时,太阳有时能把百万吨带电物质,以每秒近千公里的高速度抛向地球,即发生太阳风暴,引起地球空间环境发生急剧变化。如地球磁层被压缩,绕地球赤道的高空环电流大大增加,电离层无线电通讯的临界频率会突然改变,高能带电离子流可增加3~5个量级等等。如有时太阳耀斑爆发,能量相当于全球50亿人每人引爆100万吨TNT。这些给人类活动造成灾害的突发性空间环境变化称为灾害性空间天气。灾害性空间天气造成的危害是多方面的,可导致卫星失控或坠落,通讯中断,导航定位不准,输电网等技术系统受到损害等灾害性事件发生。也可能引起人类心血管疾病死亡率增高,皮肤癌患者增加。据统计,仅在航天领域,卫星故障中的大约40%与灾害性空间天气有关。为了研究和预报空间天气灾变规律,避免或减轻灾害性空间天气可能给人类活动带来的灾害和损失,一门把空间天气的监测、研究、模式、预报、效应、信息传输与处理以及对人美活动的影响加以综合与集成的新学科应运而生。随着我国国民经济、国防建设和科学技术曲高度发展,应用卫星、载人火箭、空间站以及地面技术系统的安全运行与剧烈变化的空间环境关系越来越密切,空间天气学就越发显得重要。我们相信,明天的空间天气预报也会像今天常规天气预报那样,为我国的建设和科学发展做出应有的贡献。根据文意,对“空间天气学”的理解不准确的一项是( )A.空间天气学像天气预报一样,为改善空问环境,促进我国的建设和科学发展做出了巨大的贡献B.空间天气学综合与集成了空间天气的监测、研究、模式、预报、效应、信息传输与处理以及对人类活动影响C.国民经济、国防建设和科学技术的发展与剧烈变化的空间环境关系的日趋密切,说明了建立空间天气学的重要性和必要性D.研究和预报空间天气变化规律,避免或减轻灾难性空间天气给人类带来损失,是建立空间天气学的目的
