在治理黄河的过程中，通过研究，科学家们根据自然界中的原型黄河构建了数字黄河、模型黄河。数字黄河是对原型黄河的数字虚拟，模拟黄河即在实验室建造原型黄河的模型。通过虚拟和模型实验一定程度上揭示了原型黄河的规律，为我国治理黄河的科学决策提供了有力的支持。借助虚拟与模型方式认识对象，是现代科学认识的重要方法，深化了关于认识过程的哲学思考，表明 ①理性认识是感性认识的深刻再现和反映  ②理性认识可以通过感性形Marlin Perkins’ keen interest in animals, especially snakes, brought him a lot of trouble when he was young. His landlady never excused him for keeping snakes in his closet. After two years of college, he left school and found a job in a zoo, sweeping the sidewalks for $3.50 a day. He was very happy about it because he could now watch animals and study them all day long. He soon became an official in charge of reptiles (爬行动物)and then director of the Buffalo Zoo.Through his snake-hunting expeditions, Perkins won his fame as a snake expert. His love for snakes is such that he thinks of them in terms of (根据) personalities. However, snakes do not have the universal appeal as he wishes. Even Perkins’ most favorite animal Bushman, the 550-pound toughest African ape, was frightened by snakes. Bushman once escaped from his cage. Nothing could draw him back. Finally a keeper went to the reptile house, got three little snakes, and dangled (摇晃) them toward Bushman. The great ape nearly tore the place apart getting back to the safety of his cage.Perkins likes all animals and takes more interest in them than many parents take in their own children. He keeps daily records on all the baby animals, takes their temperature and watches their diet strictly.
