1. Information on the storage and transportation of light hydrocarbons in natural gas
Natural gas is a gaseous fossil fuel mainly composed of methane. It mainly exists in oil fields and natural gas fields, with a small amount also found in coal seams. When non fossil organic matter undergoes anaerobic decay, it produces methane rich gas, which is called biogas. The sources of biogas include swamps between forests and grasslands, landfills, sludge in sewers, and manure, which are produced by anaerobic decomposition of bacteria. Biogas also includes gastrointestinal distension (such as farts), which most commonly comes from livestock such as cows and sheep. When methane escapes into the atmosphere, it will be a greenhouse gas that directly contributes to the worsening of global warming. This scattered methane will be regarded as a pollutant rather than a useful energy source. However, once methane in the atmosphere oxidizes with ozone, it becomes carbon dioxide and water, so the greenhouse effect caused by methane emissions is relatively short-lived. And in terms of combustion, natural gas produces much less carbon dioxide than coal and other Carboniferous fuels. The important biological sources of methane are termites, ruminants (such as cows and sheep), and human cultivation of land. It is estimated that the annual emissions of these three are 1
5, 75, and 100 million tons respectively (the total annual emissions are about 100 million tons).

3. Translate a paragraph: Gene gun experimental process (1)
All parameters should be calibrated settledprior, such as pressure, appropriate target spacer, and sample volume material for optimallloading. GDS-80 low-pressure gene delivery system, 99.999% nitrogen or helium gas cylinder, secure chain, safety issues, target spacing of 3 cm and 6 cm, 3mm filter paper, Coomassie Brilliant Blue (CBB) staining solution (0.1% Coomassie Brilliant Blue R-250 dissolved ratio of distilled water/methanol/acetic acid=45/45/10). The program requires selecting the correct bucket and assembling the whole system according to the instructions. Perform leakage test GDS-80 manually as shown. Check the pressure regulating handle by loosening it counterclockwise first. Also, ensure that the needle valve is open and the flow meter is closed by turning it counterclockwise. Open the gas cylinder valve and adjust the pressure control handle to indicate the desired pressure on the secondary pressure gauge. Loosen the differential needle valve completely and tighten it again to the valve with recommended settings (as shown in Table 1). If the pressure setting is not recommended (Table 1), please find the pressure setting area and gradually increase the thrust needle valve by adjusting the difference. F
