CHARACTERSTICS OF EST-2

1、 1. It is evident that a well lubricated bearing turns more easily than a dry one. 2. It seems that these two branches of science are mutually dependent and interacting. 3. It has been proved that there is water on Mars. 4. It was not until the 19th century that heat was considered as a form of ener

2、gy. 5. Computers may be classified as analog and digital. 6. This steel alloy is believed to be the best available here. 7. Electromagnetic waves travels at the same speed as light. 8. Microcomputers are very small in size, as is shown in Fig. 5. 9. In water sound travels nearly five times as fast a

3、s in air. 10. Compared with hydrogen, oxygen is nearly 16 times as heavy. 11. The resistance being very high, the current in the circuit was low. 12. Ice keeps the same temperature while melting. 13. An object, once in motion, will keep on moving because of its inertia. 14. All substances, whether g

4、aseous, liquid or solid, are made of atoms. 1显然，润滑得好的轴承比不润滑的轴承容易转动。 2看来这两个学科分支是相互依存、相互作用的。 3已经证明，火星上有水。 4直到十九世纪人们才认识到热是能量的一种形式。 5 计算机分为模拟计算机和数字计算机二种。 6 人们认为这种合金钢是这里能提供的最好的合金钢。 7 电磁波传送的速度和光速相同。 8 如图5所示，微型计算机体积很小。 9 声音在水中的传播速度几乎是在空气中传播速度的五倍。 10氧与氢比较，重量大约是它的十六倍。 11 由于电阻很大，电路中通过的电流就小。 12 冰在溶化时，其温度保持不变。

5、13 物体一旦运动，就会因惯性而持续运动。 14 一切物质，不论是气态、液态，还是固态，都由原子组成。 Work Area Noise Limits The sound pressure level shall not exceed 115dB(A) measured with an instrument set to “SLOW” response, at any time and at any place which is accessible to personnel, with start-up, shut-down, regeneration, maintenance operati
