Abstract: The present invention provides a perfluorophosphate-based drag-reducing agent for gas pipelines. Raw materials for the perfluorophosphate-based drag-reducing agent for gas pipelines consist of fatty acid(s), pyridine(s), fluorophosphates(s) and haloalkane(s) in a mass ratio of 2:1:1:1 to 2:3:1:2. A method for preparing the perfluorophosphate-based drag-reducing agent for gas pipelines is also provided. The perfluorophosphate-based drag-reducing agent for gas pipelines is non-toxic and environmentally friendly, has a high drag reduction percentage, a long-lasting effect, good stability and solubility, does not affect the inner surface and coatings of natural gas pipelines or gas quality, and is suitable for on-line atomization and injection.

Abstract: The present invention is a power source machinery. The power source machinery has following functions. Firstly, a slow cyclic flow is generated in a first period, and a quick and slow cyclic flow is generated in a second period. Secondly, a first huge generator drives a cylinder to rotate slowly from beginning to end, and outputs a lot of electric energy. Thirdly, supply of rotary power to a second generator and a third generator is stopped, and the rotary power is transferred to a gas pump and a water pump, which are rotating to finish the quick cyclic flow. In every period, the quick flow raise liquid in a single water-caltrop-shaped element in a lower portion to a single water-caltrop-shaped element in a higher portion, which has a function of lever, in such a manner that the power source machinery rotates continuously for a long period.

Abstract: A four-corner cut square Chinese character input method based on excellent code comprises the steps of: assigning predesigned code table to corresponding keys of a keyboard; and inputting Chinese Character according to four-corner coding of Chinese character by using the corresponding keys on the keyboard, an inputting rule of Chinese character coding including twenty cutting rules which comprise the characteristic of the excellent code combining with cutting skill. The excellent code table and cutting skill are capable of putting an end to the amphibolous codes, with this input method, most of Chinese characters don't have overlapped codes.

Abstract: An oil-based suspension-dispersion system of drag reduction polymers and the method for preparing same, characterized in adding 0.001-0.1 wt % of ultraviolet absorber and 0.001-0.1 wt % of bactericide into 50-90 wt % of vegetable oil and then mixing the obtained mixture to be homogeneous for use as dispersant, adding 2-25 wt % of separant into 10-40% of extra-high-molecular ?-olefin-styrene polymer based drag reduction polymer and crushing them into powders at a temperature of lower than ?90° C., based on the total weight of the suspension-dispersion system, and then adding the obtained mixture into the dispersant and stirring the mixture by using a high speed emulsion machine to make the mixture homogeneous and emulsified. The system offers a low viscosity of the suspended dispersion system, a high solid content up to 35%; improved high temperature resistance performance, higher flash point, improved safety, and good stability in storage.
