现代建筑的趋势是采用大面积玻璃甚至玻璃墙体,但玻璃是建筑外墙中最薄、最易传热的材料。为了节能与环保,可采用中空玻璃。中空玻璃是在两层玻璃之间的空隙内密封了干燥的空气,所以隔温性能极好。小明同学想:干燥的空气和一般空气的区别就是含水量的不同,那么空气和水的导热性是否一样呢?为此,他进行了如下的探究:用两个相同的盐水瓶,都装入热水,一个放在温度与室温相同的水中,另一个就放在空气中,为了尽量减少其他因素的影响,他把两个瓶都用木块垫起来,放在同一个桌面上,如图所示,实验时他每隔一定的时间记录一次甲、乙两温度计的示数,得到的数据如下表:

(1)对甲、乙两个瓶中的水,小明要控制它们哪些量相同?____________ 、 ___________

(2)当他们实验时的室内温度是_______℃,经过18分钟后,甲盐水瓶温度降低了37℃,乙盐水瓶温度降低了______℃,由此可以得出结论是:_________________________________________________。

(3)除了采用相同的时间内观察水温降低温度来比较空气和水的导热性能外,根据上述数据,你还可以采用______________________________________方法来比较它们的导热性能。

(4)进一步研究表明,空气的导热性也是变化的,它受到诸多因素的影响,请你写出一个影响空气导热性的因素:________________________________________________。

For years pediatricians didn’t worry much about treating hypertension in their patients. After all, kids grow so fast, it’s hard keeping up with their shoes size, let alone their blood pressure. Sure, hypertension in adults places them at greater risk of heart attack and stroke. But nobody likes the idea of starting youngsters on blood-pressure medicine they could wind up taking the rest of their lives. Who knows what previously unheard-of side effects could crop up after five or six decades of daily use

The rationale has been: kids grow out of so many things; maybe they’ll grow out of this too.

41.Now, though, comes word that high blood pressure can be destructive even in childhood.

42.Who is most at risk

Boys are more than girls, especially boys who are overweight. Their heart works so hard to force blood through extra layers of fat that its walls grow denser. Then, after decades of straining, it grows too big to pump blood very well.

43.How can you tell if yours are like the 670,000 American children ages 10 to 18 with high blood pressure

It’s not the sort of thing you can catch by putting your child’s arm in a cuff at the free monitoring station in your local grocery. You should have a test done by a doctor, who will consult special tables that indicate the normal range of blood pressure for a particular child’s age, height and sex.

44.About half the cases of hypertension stem directly from kids being overweight.

45.How can you do

You can keep your children from joining their ranks by clearing the junk food from your pantry and hooking you kids — the earlier the better — on healthy, attractive snakes like fruits (try freezing some grapes/or carrot sticks with salsa. ) Not only will they lower your children’s blood pressure: These foods will also boost their immune system and unclog their plumbing.

[A] And the problem is likely to grow. Over the past 30 years the proportion of children in the U. S. who are overweight has doubled, from 5% to 11% or 4.7 million kids.

[B] According to a recent report in the journal Circulation, 19 of 30 children with high blood pressure developed a dangerous thickening of the heart muscle that, in adults at least, has been linked to heart failure. “No one knows if this pattern holds true for younger patients as well, ” says Dr. Stephen Daniels, a pediatric cardiologist who led the study at Children’s Hospital Medical Center in Cincinnati, Ohio. “But it’s worrisome. ”

[C] Feed your children nutritious foods three times a day to keep his immune system healthy. Make sure the meals include all the food groups to ensure they are getting plenty of vitamins.

[D] Fortunately the abnormal thickening can be spotted by ultrasound. And in most case, getting that blood pressure under control — through weight loss and exercise or, as a last resort, drug treatment — allows the overworked muscle to shrink to normal size.

[E] If the doctor finds an abnormal result he will repeat the test over a period of months to make sure the reading isn’t a fake. He’ll also check, whether other conditions, like kidney disease, could be the source of the trouble, because hypertension is hard to be detected. The National Heart, Lung and Blood Institute recommends annual blood-pressure checks for every child over age 3.

[F] High blood pressure isn’t just an issue for adults; keeping kids blood pressure levels in a healthy range is also important. In a new study reported in Hypertension, researchers found that increased exercise duration among kids leads to lower blood pressure levels, however the same cannot be said for increased intensity.

[G] Meanwhile, make sure your kids spend more time on the playground than with their PlayStation. Even if they don’t shed a pound, vigorous exercise will help keep their blood vessels nice and wide, lowering their blood pressure. And of course, they’ll be more likely to eat light and, exercise if you set a good example.
