According to the monitoring material of water pollution in lanzhou section of the yellow river in recent years and 4 important attributes for lanzhou section water resource value of the yellow river , the water resource is carried and direct - viewed by fuzzy mathematics principle , and the result might be provided the basis and the support for the basin water pollution government and the water resource conservation decision making 摘要根据近年来黄河兰州段水污染的监测资料并结合影响黄河兰州段水资源价值的4个重要因素,运用模糊数学的原理,对水资源进行价值化和直观化,其结果可为流域水污染治理和水资源保护的决策提供依据和支持。
E - learning provides a friendly contact surface , a image direct - viewing learning environment , and provides the chart , the article , the sound , the picture cyclopentadiene multiple sense organ stimulating , it is advantageous to the scene establishment and the gain and maintenance of massive knowledge , it also can organizes each kind of study information and various disciplines knowledge deferring to the text and the ultra link , this is extremely advantageous to the learners ’ knowledge structure formating and the developing , also has the advantage extremely to construct the current knowledge significance , this is other learning environments is unable to achieve E - learning能够提供界面友好,形象直观的学习环境,提供图、文、声、像并茂的多重感官综合刺激,有利于情景创设和大量知识的获取和保持,还能够按照文本、超链接的方式组织各种学习信息和各学科知识,这非常有利于学习者知识结构的形成和发展,对当前知识的意义建构非常有好处,这是其他学习环境无法做到的。
This software take full advantage of the multimedia technique , especially the three - dimensional animation , to open out the abundant meanings and scientific theories in structural chemistry by using lush graphical interfaces , lifelike animation , lifesome sound effects , alluring exhibitive technique , translate bald contents and nonobjective theories into visual , direct - viewing , lively demonstration , change static and plane teaching method into dynamic and three - dimensional teaching process with attraction and infection , realize visual and enlightened teaching 本软件充分应用计算机多媒体特别是三维动画制作技术以丰富的图形界面、逼真的视频动画、生动的音响效果、引人入胜的表现手法揭示了结构化学中包括的丰富内涵和科学原理,将原来枯燥的内容和抽象的理论转变为形象、直观、生动的演示,使以前静态的,平面式的教学变为动态的、三维立体的教学过程,具有吸引力和感染力,实现了形象化、启发式教学。
