A constant magnetic flux voltage regulating structure of ultrahigh voltage self-coupling power transformer, comprising a main transformer body and a voltage regulating transformer body, the main transformer body comprising a series winding (HV), a common winding (MV), an excitation voltage regulating winding (JTV) and a third winding (LV) sleeved on the same iron core, the voltage regulating transformer body comprising a voltage regulating winding (TV) and an excitation winding (JV) sleeved on the same iron core; the series winding is in serial connection with the voltage regulating winding, and is subsequently in serial connection with the common winding; the excitation voltage regulating winding is in parallel connection with the excitation winding; the excitation voltage regulating winding is provided with a voltage regulating switch (K). The self-coupling transformer can connect two ultrahigh power grids, and by utilizing a constant magnetic flux voltage regulating method does not cause a third winding voltage fluctuation and iron over-excitation, reduces the level of insulation of a voltage regulating winding, and reduces cost and difficulty in manufacturing a voltage regulating switch.

It is an object of the present invention to provide a lens before edging and a method for manufacturing the edging lens in which the cell thickness of the liquid crystal lens structure can be kept constant without substantially containing a spacer inside the edging lens. It is characterized in that it has: a first transparent substrate; a second transparent substrate; a first sealing material without gaskets; a liquid crystal layer sealed between the first transparent substrate, the second transparent substrate and the first sealing material; And the second sealing material mixed with the spacer is arranged outside the first sealing material between the first transparent substrate and the second transparent substrate and is cut off after edging.

The invention discloses a laser flasher with big diameter for measuring the structure constant of atmospheric refractivity as well as the method for that. The laser flasher comprises two opposite-arranged reflecting telescopes and lasers on the lens cones. The incident lights reach to the secondary plane mirror after being reflected by a main parabolic mirror in the lens cones, pass the openings,attenuating pieces and narrow-band interference filters on the lens cones, and then are converged on a photoelectric detector. At transmission test, two arrangements are placed at the two ends of thetransmission path; the emitting system at one end of the path gives out modulated laser signals, after being transmitted by a turbulent atmosphere, the light signals are collected by the telescope atanther end, and go through photoelectric conversion by the photoelectric multiplier near to the focus; then the electric signals enter into a built-in control system for demodulation, sampling, processing, saving and displaying. The invention is of high accuracy and improves the accuracy in the measurements.

The invention discloses a method for measuring the vertical transport flux of atmospheric aerosol mass, comprising: calculating the real part of the effective refractive index of the atmosphere according to the measured average temperature and average pressure of the atmosphere, and calculating the real part of the effective refractive index of the atmosphere and the real part of the effective refractive index of the atmosphere Calculate the imaginary part of the effective refractive index of the atmosphere according to the atmospheric visibility, and then calculate the ratio of the mass concentration of the atmospheric aerosol to the imaginary part of the effective refractive index of the atmosphere according to the change of the mass concentration of aerosol particles and the imaginary part of the effective refractive index of the atmosphere; The ratio of the real part of the atmospheric effective refractive index to the real part of the atmospheric effective refractive index, the ratio of the atmospheric aerosol mass concentration to the imaginary part of the atmospheric effective refractive index, and the structural constant of the atmospheric effective refractive index calculated by the preset method are used to calculate the vertical transport flux of the atmospheric aerosol mass. This method can realize the objective and accurate measurement of the vertical transport flux of atmospheric aerosol mass, and has good temporal and spatial representation.
