: The development experience of major developed countries in the world shows that there is an inverted U-shaped relationship between economic growth and environmental pollution, namely the environmental Kuznets curve. China has entered the stage of middle-income development, and in order to achieve sustainable development, China attaches great importance to environmental issues. As China effectively combines industrial structure transformation with ecological environment protection, changes in industrial structure will play an important role in improving the environment. In order to explore the relationship between the industrial structure and China's environmental level, this paper constructs environmental level indicators to measure the degree of comprehensive environmental pollution, and uses industrial structure rationalization and upgrading to express the level of industrial structure optimization. Based on the provincial Panel data of 30 provinces in China from 2011 to 2017, this paper studies the relationship between industrial structure changes and environmental level by constructing a regression model. The results indicate that the optimization of industrial structure plays a positive role in promoting environmental levels. Therefore, each province should adjust measures to local conditions and optimize industrial structure to reduce adverse factors of environmental pollution, in order to achieve the goal of effectively integrating innovation and green.

There is a certain production and sales difference in the urban gas transmission and distribution system, which is composed of many factors. Part of the reason is that the gas meter takes the volume under standard conditions as the measurement unit, but the gas temperature and pressure in the meter change with the environment of the gas supply pipelines, resulting in the measurement error of the domestic gas meter without temperature and pressure compensation. By analyzing the change of annual gas temperature and local atmospheric pressure when outdoor courtyard pipelines are overhead and buried in a city, the influence of temperature and pressure change on gas volume is discussed by using gas state equation, the production and sales difference caused by metering error is calculated, and the corresponding correction coefficient is put forward, which is of certain significance to reduce the production and sales difference. It is concluded that when temperature of the gas is lower than 20°C, the measurement error of the gas meter is negative, which has caused the loss of the gas company. For domestic gas meters without temperature compensation, the product of measured gas consumption and temperature correction coefficient can be taken as the actual gas consumption to correct the measurement error of gas meters.

The influence and control of time and temperature on coalification are comprehensive. In order to quantitatively analyze the thermal kinetics of coal metamorphosis process by temperature and time, the qualitative analysis of coal metamorphosis thermodynamic equation (CMTE) based on Wu Chonglong was further verified from the mathematical point of view. Wu Chong Long's Coal Metamorphism Thermodynamics Equation (CMTE) is a ternary equation containing coal forming period or metamorphic age (time), metamorphic temperature (temperature) and metamorphic degree (reflectivity). The temperature calculated by fixing time and reflectivity is the lowest theoretical metamorphic temperature. The reflectivity calculated by fixing time and temperature is the maximum theoretical metamorphic degree. The “time-temperature ratio” is defined as the equivalent of extending million years to increasing 1°C temperature regarding coal metamorphism. This ratio is used to compare the impact of extending time or increasing temperature on improving the metamorphic degree and its significance. The results showed that in the same coal forming period, the ratio is decreased with the reflectivity increasing; at the same reflectivity, the ratio decreased with younger coal forming period. At Ro=6.1%, the calculated ratio is 3.67, which means, at Ro=6.1%, increasing 1°C is equaled extending 3.67 million.
