<P align=center class=MsoNormal style="TEXT-ALIGN: center">C题 饮酒驾车<p></p></P>
<P >据报载,2003年全国道路交通事故死亡人数为10.4372万,其中因饮酒驾车造成的占有相当的比例。</P>
<P >针对这种严重的道路交通情况,国家质量监督检验检疫局2004年5月31日发布了新的《车辆驾驶人员血液、呼气酒精含量阈值与检验》国家标准,新标准规定,车辆驾驶人员血液中的<B>酒精含量大于或等于</B><B>20</B><B>毫克/百毫升,小于</B><B>80</B><B>毫克/百毫升为饮酒驾车</B>(原标准是小于100毫克/百毫升),血液中的酒精含量<B>大于或等于</B><B>80</B><B>毫克/百毫升为醉酒驾车</B>(原标准是大于或等于100毫克/百毫升)。<p></p></P>
<P >大李在<B>中午</B><B>12</B><B>点</B>喝了<B>一瓶啤酒</B>,<B>下午</B><B>6</B><B>点</B>检查时<B>符合新的驾车标准</B>,紧接着他在吃<B>晚饭时又喝了一瓶啤酒</B>,为了保险起见他呆到<B>凌晨</B><B>2</B><B>点</B>才驾车回家,又一次遭遇检查时却被定为<B>饮酒驾车</B>,这让他既懊恼又困惑,为什么<B>喝同样多的酒,</B>两次检查结果会不一样呢?<p></p></P>
<P >请你参考下面给出的数据(或自己收集资料)建立饮酒后血液中酒精含量的数学模型,并讨论以下问题:<p></p></P>
<P >1. 对大李碰到的情况做出解释;<p></p></P>
<P >2. 在喝了3瓶啤酒或者半斤低度白酒后多长时间内驾车就会违反上述标准,在以下情况下回答:<p></p></P>
<P >1)  酒是在很短时间内喝的;<p></p></P>
<P >2)  酒是在较长一段时间(比如2小时)内喝的。</P>
<P >3. 怎样估计血液中的酒精含量在什么时间最高。</P>
<P >4. 根据你的模型论证:如果天天喝酒,是否还能开车?<p></p></P>
<P>    5. 根据你做的模型并结合新的国家标准写一篇短文,给想喝一点酒的司机如何驾车提出忠告。</P>
<P> <p></p></P>
<P><B >参考数据</B><B ><p></p></B></P>
<P >1. 人的体液占人的体重的65%至70%,其中血液只占体重的7%左右;而药物(包括酒精)在血液中的含量与在体液中的含量大体是一样的。<p></p></P>
<P >2. 体重约70kg的某人在短时间内喝下2瓶啤酒后,隔一定时间测量他的血液中酒精含量(毫克/百毫升),得到数据如下:<p></p></P>
