The invention discloses a green plant windbreaking plate structure based on wind power generation, and relates to the technical field of natural disaster protection. The green plant windbreaking platestructure based on wind power generation comprises a windbreaking plate frame, a windbreaking plate, functional side columns and a connection blocking frame, wherein side rotating frames are arrangedon the top of the windbreaking plate frame, two sides of the windbreaking plate frame are arranged to correspond to the functional side columns, the connection blocking frame is installed between thefunctional side columns, the functional side columns and the connection blocking frame can be continuously arranged, a wind power rotating shaft is installed on the connection blocking frame, and wind power fan blades are arranged on the top of the wind power rotating shaft. The green plant windbreaking plate structure based on wind power generation is provided, the problem that for existing large-area green plant cultivation, there are no structure devices capable of automatically protecting a whole park against strong wind on a large scale when the strong wind comes is solved, the device can be automatically started in windy weather, and can be controlled through remote commands, and no external power supplies or wires are needed, so that installation positions are unlimited.

The invention relates to an oil field construction technology by means of a biological surfactant. The construction technology comprises the steps that on the condition that 20-22 Mpa pressure is applied to a ground well hole, after it is guaranteed that piecing and leaking do not occur, prepad fluid of which the concentration is 2.5-3.0 wt.% is injected into an oil well, and the usage amount is 5-7 cubic meters; then treating fluid of which the concentration is 2.0-2.2 wt.% is injected into the oil well, the usage amount is calculated by the formula Q=pi(r^2).h.phi, wherein Q is the total liquid amount, r represents the treating radius, h represents the effective thickness of the oil well, and phi represents the porosity; finally, waste water is adopted to replace the fluid, and the usage amount is 5-10 cubic meters; after the well is shut down for at least 72 h, a construction tubular column is put out, and well completion is achieved after an original production tubular column is put down. The biological surfactant used in the construction technology has the advantages that the extremely high capacity of releasing all solid surface hydrocarbon (oil) is achieved, secondary pollution cannot be caused to the stratum, disorder cannot be caused to a crude oil dehydration and sewage treatment system, and the oil production can be greatly improved; in addition, the construction technology is convenient to operate, safe and reliable, and suitable for wide-range usage.

The invention provides a compound, a preparation method thereof and a purpose of the compound in preparing a drug. The compound is a compound shown in a formula (I) or a stereoisomer, a geometric isomer, a tautomer, a nitrogen oxide, a hydrate, a solvate, a metabolite or a pharmaceutically acceptable salt of the compound shown in the formula (I). The compound provided by the invention can transform peramivir in an injection dosage form into an inhalant dosage form, improves the medication compliance of the peramivir and enables the peramivir to have the characteristics of convenience in use and suitability for use in a wide range; and in addition, the drug directly acts on a respiratory tract and a lung infected with an influenza virus after being inhaled, so that single administration is hopefully realized, and the drug can effectively have double actions of prevention and treatment to the influenza. A chemical formula is described in the description.
