多尺度科学:面向21世纪的挑战

MULTISCALE SCIENCE: A CHALLENGE FOR THE TWENTY-FIRST CENTURY

多尺度科学是一门研究各种不同长度尺度或时间尺度相互耦合现象的科学．多尺度科学的研究领域十分宽广，涵盖的学科之多难以一一罗列．对于诸如流体动力学、材料科学、生物学、环境科学、化学、地质学、气象学和高能物理之类的各门科学，多尺度科学是它们的核心．多尺度科学目前在国际上处于刚刚起步的阶段．正如非线性现象和随机现象被认为是属于交叉学科并得到广泛重视一样，多尺度科学因其处于当代科学的许多极富挑战性问题的核心地位，发展前途未可限量．因此，在我国有必要抓住机遇，大力开展多尺度科学及其方法的研究．

Multiscale science is the study of phenomena that couple distinct length or time scales.It would be difficult to overstate the scope of multiscale science, which is centraJ to such diverse fields as fluid dynamics, materials science, biology, environmental science, chemistry, geology, meteorology, and high-energy physics, Just as nonlinear and stochastic phenomena have been recognized as cross-catting approaches, we see that multiscale science lies at the heart of many of the most challenging problems of contemporary science. There is thus both a need and an opportunity to deveop the methods of multiscale science.
