From Dr. R. S. Scorer of Britain’s Imperial College of Science comes the latest theory about the cause of lightening flashes. Dr. Scorer believes the cause is hail falling through super - cooled clouds, lee particles bouncing off the falling hail acquire a positive charge and rise to the top of the cloud while the hail carries a negative charge to the bottom of the cloud.

There are many problems in our modern world. One very()serious problem is energy. We get a great () of energy we need from coal, gas, and oil. However, the () of energy which we use is () every year, and we only have enough coal, gas, and oil for the next twenty or thirty years. How will we live () the energy which these things give us？ Scientists are looking for () to this problem. They are looking for new () to produce energy. For example, they are working with new ways to () energy from the light and heat of the sun. They are also working with plans which produce energy from () of the oceans. All of the new methods () scientists are finding are still very expensive, but perhaps they will help solve our energy problems () the future.

气体的粘度随压力增高而增高。在低压时，气体粘度随温度升高而增加，随着压力的增加，温度升高对粘度增大的影响越来越小，当压力很高时（100×105Pa以上），气体粘度随温度升高而降低，明显表现出类似于液体的性质。Table 1-13 shows the dynamic viscosity of methane at different pressures and temperatures. It can be seen from the table that the viscosity of gas increases with the increase of pressure. At low pressure, the gas viscosity increases with the increase of temperature. With the increase of pressure, the influence of temperature increase on the inc
