CASING SEAMLESS 7” 23LBS / FT K55 BUTTRESS RANGE 3

Q: There are several forms of energyWhat are they called? What is the use?: The primary energy is divided into renewable energy (hydro, wind and biomass) and non renewable energy sources (coal, petroleum, natural gas, oil shale, etc.). According to the production method can be divided into primary energy (natural energy) and two energy (artificial energy). Primary energy refers to the nature the natural form and without processing or conversion of energy resources, energy resources including a hydraulic renewable and non renewable coal, petroleum and natural gas resources, three kinds of energy including water, oil and gas, is the core of primary energy,

Q: How to solve the energy problem: Market economy is open, China should vigorously develop the international energy market, make full use of the international and domestic two kinds of resources, and expand the way and quantity of energy imports

Q: What is terminal energy consumption: 3 the energy used as a material refers to the use of some of the energy does not constitute a product of the entity only play a supporting role in the consumption of such as washing gasoline diesel oil kerosene lubricating oil used in various equipment4 process energy refers to the process in the production process is not used as raw materials, nor as a fuel, power use of the process of energy use, such as the production of calcium carbide power, electrolytic powerThe terminal energy consumption is equal to the energy consumption of terminal energy

Q: Can the total energy consumption (equal value) be calculated in terms of the sum of the equal value of electricity and other energy: Equal value is the amount of energy produced by another unit of energy consumed by a unit of energy.

Q: Definition of low carbon energy: Low carbon energy is an alternative to high carbon energy sources, it refers to carbon dioxide and other greenhouse gas emissions low or zero emissions of energy products, including nuclear energy and a part of renewable energy.

Q: I would like to ask you, China's electronic products have the use of energy classification, if so, what is the specific classification?: Level 2 means comparison;Level 3 indicates that the energy efficiency of the product is the average level of the Chinese market;

Q: Trademark registration of energy and environmental protection is the first category: Article 02: paint, varnish, paint, rust and wood preservatives, colorants, mordant, raw natural resins, painters, decorators, printers and artists with metal foil and powderArticle 03: laundry bleach and other materials, cleaning, polishing, scouring and abrasive preparations, soap, spices, essential oils, cosmetics, shampoo, toothpaste

Q: What is the comprehensive calculation of energy production?: Energy production [statistics] the statistics reflect energy production scale, energy production structure, main indicators of production results and development speed, for the preparation of energy production plan, check the energy production schedule, reasonable composition analysis by energy, provide an important basis for the rational development of energy. According to the origin of energy, it can be divided into primary energy output and two energy output.

Q: At present, what are the main types of new energy vehicles?: Hybrid electric vehicle:Refers to the use of conventional fuels, while with motor or engine to improve low-speed power output and fuel consumption models. In accordance with the different types of fuel, hybrid vehicles can be divided into two types of gasoline hybrid vehicles and diesel hybrid vehicles. At present, the mainstream of hybrid vehicles in China are mainly gasoline hybrid, while the international development of diesel hybrid models are relatively fast.

Q: And the world's oil futures and other energy futures prices related to China's domestic futures varieties which futures? Seek expert futures and futures experts cited. Thank you: Third: for example, methanol, linear low density polyethylene, polyvinyl chloride, sugar, purified terephthalic acid, etc.. Note: white sugar is a substitute for oil, so it is related to the rise and fall of oil
