| 摘 要： | ２１世纪的生命科学有两大前沿领域：分子生物学和神经生物学，前者研究人体生命过程的基因调控机制，而神经生物学则以探索人脑思维的奥秘为主要目标，正电子层析成像（ＰＥＴ）是研究人体内部分子相互作用动力学的和最有力的方法，并可研究脑的功能定位，ＰＥＴ的化学精度已达到ｐ ｍｏｌ水平，其空间分辨率为毫米数量级。ＰＥＴ将对２１世纪生命科学的巨大进展，起决定性的推动作用。

| Abstract: | There are two major frontiers of life science in 21 century, the molecular biology and the neural biology. Molecular biology investigates the mechanism of genetic regulation of life process within the human body, while the aim of neural biology is to explore the secret of mind in the brain. Positron emission tomography (PET ) is the most effective and powerful method to investigate the kinetic mechanism of molecular interaction in the human body and the fUnctional localization of the brain. The chemical accuracy of PET reaches the level of pico molar and its spatial resolution is the order of milimeter. The PET may give a definite impact to the great progress of life science in 21 century. |
