It applied to aerospace control engineering widely now.
According to the above ideas, when sneaking passage analysis to a thermal system, the key is to establish the equivalent rules between thermodynamic system and circuit system.
That might affect the closing of valves and cause damage. 7) Mechanical parts and pipe wear may affect the system runs normally 8) It is possible that corroded components in thermodynamic system maybe undergo chemical reaction with some certain fluids catalyzed by certain material 9) Several different kinds of fluid flowed over the same pipe may occur fluid mixed and happen some chemical reactions in some cases. 10) Scrap emitted from pipes may feedback into other pipelines 11) Each branch of various loops may not prevent sneak backflow 12) If valves in a system can realize different functions when they are in different operating mode, valves at the process of closing will produce unexpected actions. 13) Different operating mode has different pressure level, it may exceed predetermined range in some cases. 14) Each valve of system opens in the wrong order. 15) Multiple valves when they are opened or closed at the same time may cause undesirable effect. 16) The opening status of

Removal of organic matters in pesticide wastewater by supercritical water oxidation Donghai Xu 1, a *, Shuzhong Wang 1, b, Chuanbao Huang, Xingying Tang, Yang Guo, Lili, Qian 1 Key Laboratory of Thermo-Fluid Science & Engineering, Ministry of Education, Xi’an Jiaotong University, Xi’an, Shaanxi Province 710049, China a haidongxu93346423@aliyun.com, b szwang@aliyun.com Keywords: Supercritical water, Oxidation, Pesticide wastewater, Removal efficiency.
Because when energy is self-sufficient, the mass concentration of the organic matters is at least in the range of 3%–4%.[33,34] However, previous studies mentioned that organic compounds at high concentration were easy to produce tarry materials such as char in supercritical water, resulting in the reduction of conversion efficiency[35,36].
However, tarry materials such as char and tar, are not detected in our tests, and this may be due to unique properties of feedstock.

As a method to research into the material resource metabolic action of nature-economy-society three-dimensional ecosystem, the basic thought of emergy analysis is to transfer different types, incomparable energy and materials fluid or stored in the ecology economic system into solar emergy of the same standard, which is count by sej.
What’s more, the emergy analysis is assisted by a specific set of standard system to perform comprehensive quantitative study on a certain district population flow, material flow, energy flow and information flow objectively.
Ever since the emergy analysis was established, it has been extensively employed in different layers of ecology economic system analysis, environmental value of resources evaluation, ecological engineering evaluation, development orientation of regional sustainable development evaluation, and so on.
Renewable resource emergy includes renewable natural environment emergy and organic emergy, they are key factors of Hubei agriculture sustainable development.
