怕还有难度。5美日联手研制激光武器激光是一种比太阳表面亮度高出100亿倍的光,[link widoczny dla zalogowanych],速度为30万km/s。激光炮亦称“空中激光”武器,主要借助激光很强的烧蚀性能、辐射和强激波来破坏目标,具有攻击速度快、转向灵活、不受电磁干扰的特点。激光武器的发展已有30多年历史,有些关键技术已取得突破,美国、俄罗斯、法国、以色列等国都成功进行了各种激光打靶试验。从理论上讲,激光武器可以准确打击几万千米以外的目标,但现在已经面世的战术激光武器打击距离一般在20km左右,而战略激光武器的打击距离为300km~400km。激光武器精度高,不需要考虑提前量,几乎没有误差。激光炮可在500ms钟内将炭块加热到9O03oC以上,能在瞬间把坦克的钢板击穿,[link widoczny dla zalogowanych]。激光炮一旦打击目标,将会造成仪器失灵、操作装置失效或爆炸燃烧,是未来精确打击卫星、飞机、导弹和坦克等装置的利器。为了研制激光炮,美国已投入了上百亿美元,不过仍有好多技术问题尚未解决。2005年1月10日美国与日本合作,形成了美日联手研制“空中激光”武器的态势。(未完待续)本文是《科技情报开发与经济))2005年第11期封二“卫星导航定位系统(一)”的续文。(责任编辑:白尚平)第一作者简介:曹来发,男,[link widoczny dla zalogowanych],1936年4月生级工程师,华北电力设计院,北京市石景山区实验中学总务处转,[link widoczny dla zalogowanych],100043.TheSatelliteNavigationPositioningSystem(II)CAoLai-faABSTRACT:Thispaperintroducesthreekindsofsatellitenavigationpositioningsystems,expoundstheattitudeofAmericatotheGalileosystem,anddescribesthedevelopingpointsofAmericanspaceweapons.KEYWORDS:satellitenavigationpositioningsystem;Galileosystem,[link widoczny dla zalogowanych];spaceweapon(上接第133页)OntheGameintheAccountingInformationQualityGUoLi-xianABSTRACT:Thesocietyispayinggreatattentiontothequalityoftheaccountinginformation.Whetherornottheaccountinginformationsatisfytherequirementoftheusersoftheinformationdependsonwhetherornotthepeopletreattherelationbetweenthereliabilityandthecorrelationoftheaccountinginformation.Inrecentperiod,ourcountryshouldincreasethecorrelationoftheaccountinginformationasmuchaspossibleunderthepreconditionthatthereliabilityoftheaccountinginformationisguaranteedbasically,andfurtherrealizetheusabilityoftheaccountinginformation.KEYW0RDS:accountinginformation;financialmanagement;dataanalysisl36
