22、电来产生微波的。微波炉是怎样烹饪食物的？交流电可以产生频率很高的电磁波微波。水分子有正极和负极， 因此当水接受正负交替的微波能量时，水分子会迅速转动。这有点儿类似用磁石把平面上的大头针吸得团团转的情形。微波炉用交流电产生的微波，使食物中的水分子以每秒钟数亿次的速度旋转，造成分子之间巨大的摩擦，使食物迅速加热。事实上， 质量检测机构只关心微波炉是否存在微波泄漏的情况。令人惊讶的是， 这些质量检测机构从未质疑微波食品本身是否安全。1991 年，由于一场公众瞩目的官司，人们开始意识到微波食品并非百分之百安全。一位名叫诺尔玛?利沃特的妇女的家人为她的误死起诉。诺尔玛去医院进行髋部更换手术。手术很成功，

23、 诺尔玛却死了。 诺尔玛死于一次输血之后，血液是经过微波炉加温的。这是第一次有重大证据表明微波炉对被加热的物品的化学性质造成了破坏。 如果仅用微波炉把血液加热到体温，就能使血液包含致人于死命的毒性，那么我们用更高的温度在更长的时间内加热食品，又会有什么情况呢？食物的分子吸收了大量能量。这些能量足以分解蛋白质的分子结构，导致了通常情况下不会发生的分子异变。结果许多新的奇怪的分子出现了。问题就在这里， 食物的分子结构发生了改变， 产生了人体不能识别的分子。这些奇怪的新分子是人体不能接受的，有些有毒性，还可能致癌。因此，经常吃微波食品的人或动物，体内会发生一定的生理变化。瑞士皇家科技协会的汉斯?赫尔

24、特博士和博尔纳德博士发现，微波加热破坏了食物的营养万分。 他们测量了吃微波食品志愿者血液中的病理变化。令人震惊的是， 这些人血液中的红细胞减少了， 这意味着血液携带的氧减少，人体组织无法得到所需的氧。相反， 白细胞和胆固醇增加了。 白细胞增加会引起人体的压力和紧张，通常只有当人体感染急性疾病、细菌感染或细胞受损坏时，白细胞才会上升。此外，淋巴细胞和白细胞对产生抗体有重要作用。俄罗斯的研究表明，遭受微波辐射不仅有损健康，而且食用微波食品同样会造成严重的健康问题。 在美国， 俄利根波特兰的科学家也曾发表过俄罗斯的研究发现。无论何种食物一旦经过微波加热都会产生已知的致癌物。肉类、奶类、谷物、水果和蔬

25、菜都会产生引起癌症的化学物。 吃微波食品的人消化系统紊乱，淋巴系统发生障碍，血液中癌细胞增加。经常吃微波食品的人更容易患胃肠癌，消化系统也会逐渐出现问题。科学家还发现， 每台微波炉都会泄漏辐射， 微波烹饪的食物会产生有毒和致癌的附加物，微波食品的营养价值减少了60%至 90%，包括矿物质和生化酶，维生素B、C 和 E 等物质， 甚至连蛋白质的营养万分也减少了。荷尔蒙也会发生异常情况，特别是男性和女性荷尔蒙的分泌和平衡出现异常。长期食用微波食品会导致永久性的脑损伤，造成记忆力下降，注意力难以集中， 情绪波动， 智力下降。17认真阅读全文，为本文拟写一个标题。（3 分）_ 18结合文章内容，谈谈最

48、们的运动似乎恰恰遵循着严格的规律。科学家们通过大量的观察和试验，发现飞行动物和游水动物的运动过程中存在着一个神秘的常数，那就是它们的翅膀或尾巴的振动频率、振幅以及运动速度三者之间的关系 振动频率乘以振幅再除以运动速度，计算得到的数值总是落在0.20.4 之间。比如，世界上最小的鸟类 蜂鸟，其双翅展开仅有10 厘米左右，飞翔时振幅大约是 20 厘米。蜂鸟的飞行速度非常快，大约能达到50 米/秒。而科学家们以往观察到的蜂鸟飞行时双翅振动频率在5070 赫兹之间，根据上述公式计算出来的蜂鸟的运动常数就落在0.20.4 之间。与蜂鸟体形相差悬殊的海豚也是科学家们观察的一个对象。成年海豚的体长一般在3米

49、左右，在大海里游动时，海豚尾巴振动的振幅大约是1 米，频率是每分钟30 次左右，游泳速度是每小时100 公里，根据公式计算出来的海豚的运动常数是0.3，也落在0.20.4 之间。这不仅仅是巧合。研究者们作了大量的试验，发现几乎所有的飞行动物和游水动物的运动机制中都存在这个神奇的常数，事实上，只有当这一运动常数的值处于O.20.4 之间时，动物们才能达到最佳的运动状态。虽然目前科学家们还不清楚为什么会存在这个运动常数，它的值又为什么恰恰落在0.20.4 之间，但这一神奇的常数似乎像物理学中著名的光速不变原理那样放之四海而皆准，也像光速一样神秘。 它能够帮助生物学家们根据动物化石的身体构造判断出那

50、些早已灭绝了的动物曾经具有怎样的运动速度。甚至不能排除，这一常数很可能对外星生物也同样适用。很多科学家都表示：“ 如果在其他星球上真的存在游水生物或飞行生物的话，我们相信，它们的运动也遵循着同样的规律。”此外，这一常数还能帮助军方研制出各种高性能的飞行器。比如说，一个翼长15 厘米、翼振振幅为10 厘米的机械间谍如果要做最有效飞行的话，其最佳翼振频率应该是30次/秒左右。目前，美国军方已经着手研制类似于飞鸟的有翼飞行器，在配备上微型摄像机之后， 这样的机械鸟将可能深入敌方的任何机密要塞进行刺探。当然， 他们最感兴趣的还是能够研制出体积更小，无孔不入的机械昆虫，相信这一天的到来也为时不远。（选自
