社会发展到今天，能源危机开始困扰人类，人们正在寻找各种可能的未来能源，以维持人类社会的持续发展．热核聚变是在上亿摄氏度的高温条件下利用氢的同位素氘、氚在可控情况下发生的核聚变．聚变反应中释放出来的核能提供了大量的热量，就像造出一个“人造太阳”．反应后的生成物是无放射性污染的氦，预期于2010年建成的实验反应堆，可以在16 min产生1.44×10¹² J的热量，据媒体报道：1L海水提取的氢的同位素，在完全聚变反应中释放的能量，相当于300L汽油完全燃烧所释放的热量。请根据所提供的数据进行计算，并回答以下问题：

（1）若汽油的密度约为0.7×10³ kg/m³，300 L汽油的质量是多少？（1L=1×10^-3 m³）

（2）若汽油的热值为4.6×10⁷ J/kg，300 L汽油完全燃烧能释放多少热量？

（3）从1.49×10²L海水中提取氢的同位素，在发生聚变时可以产生1.44×10¹²J的热量，若这些热量转化为电能的效率为50%，则它可以供给一台功率是200 W的电视机正常工作多少小时？

（4）你知道吗，在安徽省合肥市科学岛上也有一台“人造太阳”，它名为托卡马克．阅读了上述材料和数据后，你一定会有很多感受，谈谈你对“人造太阳”的认识。

肾阳不足之泄泻特点为

A．大便时溏时泻，水谷不化，面黄肢倦
B．腹痛肠鸣，粪便臭如败卵
C．泄泻，胸胁胀闷，因情志增剧
D．腹痛肠鸣即泻，泻后则安，形寒肢冷，腰膝酸软
E．泄泻如水样，伴恶寒发热，肢体酸痛

For many centuries，countless scholars have asked the question：What is beauty? As designers update the latest fashions and artists create their masterpieces, what is considered beautiful changes at an alarming pace.

Fifty years ago，the full-figured Marilyn Monroe was a symbol of the American aesthetic(美学的)value；today，many Hollywood actresses different in appearance from Marilyn’s have taken her place. However，aesthetic values not only differ from generation to generation，but do so along cultural lines as well. Often, what is considered disgusting to one civilization is just the aesthetic appeal in another. Thus it is difficult to give an absolute definition(定义)of beauty.

As fundamental(基础的)physicists，my colleagues and I like to believe that we are involved in a search for a beauty that affects definition. The beauty that we search for is not what is set up through the work of people and subject to the tastes, but rather what has been laid down by nature Physics allows its students to look past outer appearances，into a deeper beauty. As a human being，I am attracted by the visual appeal of a wave crashing on the beach. As a physicist, however I am able to see the deeper beauty of the physical laws that govern such a phenomenon.

In truth，since Albert Einstein put forward the idea that there might be one main physical theory that governs the universe，aesthetics have become a driving force in modern physics. Einstein and other later physicists have discovered that：Nature, as its most fundamental level，is beautifully constructed. The extraordinary simplicity of the laws that govern the universe is really breathtaking . As Einstein said, it would seem more likely that we should find ourselves living in a“chaotic(无秩序曲)world，in no way graspable through thinking”. Yet we are now closer than ever to a full understanding of the universe’s beautiful clockwork. As new discoveries and technologies allow us to examine the physical world on deeper and deeper levels，we find that the beauty itself becomes much deeper.
