摘要: When Dunnoyer (1911) produced the first molecular beam and showed that atoms inside a sufficiently evacuated chamber move along straight lines, he created one of most important research instruments for 20th century physics chemistry. An unusually long extremely fruitful period experimental investigations, choosing new angles attack again again, led to an important, wide-reaching ground-breaking knowledge base.
