Dalton wondered why the heavier and lighter gases in the atmosphere did not separate as oil and water do. He finally concluded that the constituent (61) must exist in the form of tiny particles or atoms and that these (62) be completely mixed together in the atmosphere.

He also said that the administration of President Arling was determined to increase investment in high technology industries, upgrade aging plant equipment in heavy industry, and encourage workers to increase productivity.< [判断题]操作机构用墙或金属板与该断路器隔离或装有远方操作机构的室内高压断路器可单人操作。
