选择食管癌前状态转归过程的动态研究作为切入点和突破口，提出了一项为期５年的试验研究设计纲要，旨在有效解决食管癌综合防治研究中，现阶段需要深入研究的重点和难点问题。应用时只需依据实际条件，具体选定状态变量向量和伴随变量向量的分量，即可按设计规定的程序予以实施。
The dynamic research on the process of pre-esophageal cancer outcomes was selected as the entry point and breakthrough point. A five-year experimental study design outline was proposed to effectively address the key issues and difficulties in the comprehensive prevention and treatment of esophageal cancer at this stage. problem. When the application is based on the actual conditions, the components of the state variable vector and the concomitant variable vector are specifically selected, and can be implemented according to a design-defined procedure.
