This invention discloses a method for suppressing pressure pulsation in hydraulic turbines based on synergistic jet water supply, relating to the field of hydraulic machinery flow control and operational stability technology. The invention first modifies the target turbine by adding a top cover water supply channel and a main shaft center hole water supply channel. Then, it conducts operating condition tests on the target turbine to analyze and obtain the target load operating range. Based on this target load operating range, synergistic water supply tests are performed on the target turbine to further analyze and obtain the optimal combination of synergistic water supply parameters within the target load operating range. Finally, water is supplied to the target turbine based on the target load operating conditions and the optimal combination of synergistic water supply parameters. The synergistic water supply proposed in this invention comprehensively suppresses pressure pulsation from the bladeless region, runner region to the draft tube region without significantly reducing turbine output and efficiency.

The embodiment of the invention discloses a display panel, a driving method thereof and a display device.The display panel comprises N types of display areas, the N types of display areas comprise the ith type of display area and the jth type of display area, the display panel comprises M display parts, the M display parts comprise the first display part and the second display part, the first display part comprises at least one ith type of display area, and the second display part comprises at least one jth type of display area. The first display part comprises at least one ith display area, the second display part comprises at least one ith display area, at least one jth display area is arranged between the ith display area included in the first display part and the ith display area included in the second display part, and the luminous time periods of the ith display area and the jth display area are at least partially not overlapped so as to reduce the same time period. The number of the sub-pixels driven by the power supply voltage line in the display panel is reduced, so that when the sub-pixels emitting light in the same time period emit light with the same brightness, the rising amplitude of instantaneous current on the power supply voltage line is reduced, the voltage drop on the power supply voltage line is reduced, and the uniformity of a display picture is improved.

The present disclosure relates to the technical field of chloroacetic acid tail gas treatment, and one embodiment of the present disclosure provides a processing device for monochloroacetic acid synthesis tail gas, which comprises a first acetic acid absorption tower, a second acetic acid absorption tower, a third acetic acid absorption tower and a gas inlet pipeline, and further comprises heat preservation covers, sun protection covers, fixing mechanisms, heat preservation and sun protection mechanisms and connecting mechanisms, two heat preservation covers are movably sleeved on the first acetic acid absorption tower, the second acetic acid absorption tower and the third acetic acid absorption tower, and the sun protection covers are installed on the outer sides of the heat preservation covers. Through the above technical solution, the technical problem that the tail gas inlet pipeline and the acetic acid recovery tower in the processing device for monochloroacetic acid synthesis tail gas lack effective heat preservation and sun protection structures in the prior art, so that the temperature inside the tail gas inlet pipeline and the acetic acid recovery tower is affected by the outside world and rises, the tail gas is greatly lost when the air temperature is high, and the tail gas is easily greatly lost, thereby affecting the recovery efficiency of acetic acid is solved.
