工程化学

The law of conservation and transformation of energy is the chief basis of physical, astronomical and chemical reasoning as well as of engineering practice.

能量守恒和能量转换定律不仅是工程实践的主要基础，而且也是物理、天文以及化学等方面的主要基础。

With the modernization of scientific and technological progress and industrial development, physics, chemistry, biology, engineering, aerospace, medical, economic and financial areas of the many principles and laws can be described as an appropriate ordinary differential equations, such as Newton's laws of motion, gravity law, law of conservation of mechanical energy, energy conservation law, the law of population development, ecological population competition, disease transmission, genetic variation, the trend of the stock's up V, the floating interest rates, the market equilibrium price changes.

随着科技进步和工业现代化的发展，物理、化学、生物、工程、航空航天、医学、经济和金融领域中的许多原理和规律都可以描述成适当的常微分方程，如牛顿的运动定律、万有引力定律、机械能守恒定律，能量守恒定律、人口发展规律、生态种群竞争、疾病传染、遗传基因变异、股票的涨伏趋势、利率的浮动、市场均衡价格的变化等。

Cryostat tank / tank temperature / low temperature tank is widely used in petroleum, chemical, electronic instruments, physical, chemical, biological engineering, medicine and health, life science, light and food, materials testing and chemical analysis, research departments, universities, businesses quality control and production departments work for the user to provide a hot and cold controlled temperature constant uniform field source, the test samples or products produced by a constant temperature test or test, but also as a direct heating or cooling and auxiliary heating or cooling of heat or cold source.

低温恒温油槽/恒温油槽/低温油槽广泛用于石油、化工、电子仪表、物理、化工、生物工程、医药卫生、生命科学、轻工食品、物性测试及化学分析等研究部门，高等院校，企业质检及生产部门，为用户工作时提供一个热冷受控，温度均匀恒定的场源，对试验样品或生产的产品进行恒定温度试验或测试，也可作为直接加热或制冷和辅助加热或制冷的热源或冷源。

At last, we debugged and studied the dephosphorization by chemistry precipitation in a case of wastewater treatment project on the base of the study and get a satisfactory result.

在此基础上，我们对某工程的化学除磷进行了实际调试与研究，得到了较好的处理效果。
