		<description><![CDATA[反坦克地雷是专门用于对付坦克的地雷是坦克的“克星”。这个家族主要有反履带地雷、反车底及履带地雷、反侧甲地雷、反底甲地雷等成员。炸“脚”的反履带地雷，是最早出现的一种反坦克地雷。这种地雷必须是坦克压上后起爆，并靠雷体炸药炸断坦克履带。炸“脚”破“肚”兼有的反履带反车底两用地雷，其特点是利用热（红外线）、磁、声或振动电子传感控测目标和起爆地雷。穿“腰”的是反侧甲地雷，由反坦克火箭筒技术发展而来，它被布设在坦克必经线路的侧旁隐蔽处。采用被动红外线或毫米波雷达等传感器（对目标定位、测距、区分）和威力更大的空心装药直穿坦克侧装甲。破“肚”的反底甲地雷有两种：一种是利用触发杆引信和破甲弹空心装药使在雷起爆后形成金属射流击穿底甲，威力较小；一种是采用大锥角（120℃以上）药型罩空心装药，使地雷起爆后形成高速翻转弹丸穿透底甲。这种地雷需要坦克在其上方通过时起爆，威力明显提高，而且对车内人员还有威慑作用。 相关文章为什么主战坦克比普通坦克厉害？(0) 为什么有的坦克能在陆地和水中行使？(0) 最新评论<table class="wumii-related-items" cellspacing="0" cellpadding="3" border="0"  style="clear: both;">

		<description><![CDATA[战后第二代坦克指的是20世纪60～70年代期间研制的坦克。 由于它既能完成过去中型和重型坦克所承担的任务，又具有中型坦克的机动能力，同时在火力和装甲防护方面达到或超过了重型坦克的水平，形成了一代新型坦克，叫第一代主战坦克。进入80年代后，世界各国对第一代主战坦克不断地进行现代化改进，第二代主战坦克陆续问世。目前世界上装备的比较先进的主战坦克有美国的M1A2、M1，俄罗斯的T-80、T-90，德国的“豹”Ⅱ，英国的“挑战者”等坦克。其共同特点是：坦克炮口径大、射程远、射速高、威力大；采用复合装甲、反应装甲或其它特种装甲，防护能力比其他任何坦克都强；装有先进的火控系统和完善的夜视夜瞄设备， 可全天候作战；可在核、 化学、生物战争条件下使用；发动机功率大、 机动能力强、行驶速度快等。主要性能是：越野时速达30～55千米， 最大行程为300～650千米，最大爬坡度约30℃，越壕宽2.7～3.15毫米，过垂直墙0.9～1.2米，涉水深1～1.4米，潜水深4～5.5米。这些特点都是普通坦克无法比拟的。 相关文章为什么反坦克地雷是坦克的克星？(0) 为什么有的坦克能在陆地和水中行使？(0) 最新评论<table class="wumii-related-items" cellspacing="0" cellpadding="3" border="0"  style="clear: both;">

		<description><![CDATA[水陆两用坦克是一种既能在陆地上行驶，又能在水中航行、作战的坦克。人们为了提高水陆两用坦克在水中的浮力， 采用了薄型钢板制作外壳， 车体设计成又轻又长，前部呈船形。所有拼接部位都焊接起来，防止漏水，使坦克具有良好的密封性，以增加坦克的浮力。坦克的动力则采用了多种多样的方案。有的坦克采用了特制的履带，犹如水车的水斗，通过履带的旋转，履带片不断把水排向后方，从而推动坦克前进。有的则在坦克的尾部装上螺旋桨推进器，发动机通过传动装置带动螺旋浆转动，坦克就像船一样前进了。还有的装上了喷水式推进器，通过向后喷水获得反作用力，推动坦克行驶。 世界上第一辆坦克 1915年9月，英国政府采纳了恩斯特·斯文顿的建议， 试制了第一辆坦克样车——“小游民” 。 车身后伸出一对尾轮， 用于转向，也用于保持平衡。 相关文章为什么反坦克地雷是坦克的克星？(0) 为什么主战坦克比普通坦克厉害？(0) 最新评论<table class="wumii-related-items" cellspacing="0" cellpadding="3" border="0"  style="clear: both;">

<blockquote><p><strong>世界上第一辆坦克</strong><br />
1915年9月，英国政府采纳了恩斯特·斯文顿的建议， 试制了第一辆坦克样车——“小游民” 。 车身后伸出一对尾轮， 用于转向，也用于保持<span class='bm_keywordlink_affiliate'><a href="http://www.10why.net/tag/平衡" target="_blank">平衡</a></span>。</p></blockquote>
