The present invention provides a method for detecting the anti-island protection performance of an inverter. An RLC circuit is serially connected between the inverter and a grid connection switch, the resonant frequency of the RLC load is set as three different numerical values for enabling the same to present resistance, capacitance and inductance, and a time value from the disconnection of the grid connection switch to the operation stop of the inverter under detection is recorded after a fundamental current value of the grid connection switch is set to a different value each time; and weighted calculation is performed on the time value to obtain a test result and grade evaluation of the anti-island protection ability of the inverter. By adoption of the detection method provided by the present invention, the problem that the anti-island protection ability of the photovoltaic inverter is difficult to precisely evaluate is solved; the anti-island protection performance of the inverter is comprehensively and objectively reflected; and meanwhile the phenomenon that a part of inverters cannot correctly reflect the anti-island ability of the inverters with respect to characteristic load design is effectively avoided, a technical support is provided for the existing method for detecting the anti-island protection performance, and related standard systems in the field of detection of the anti-island protection performance are further enriched and perfected.

In an approach to quick browsing of content displayed on a computing device, a computer monitors a scrolling operation in a first display mode on a computing device in which a plurality of information items are displayed. The computer determines whether a speed of the scrolling operation exceeds a threshold value, and then in response to the speed of the scrolling operation exceeding a threshold value, switches the first display mode to a second display mode.

A method and pre-corrector for correcting signals in radio frequency links are provided. The method comprises: obtaining, in a time division order, a set of pre-distortion vectors for the respective radio frequency links by using one and the same set of pre-distortion vector obtaining means based on difference in arrival time of cyclic delay frames in the respective radio frequency links of a multiple input multiple output (MIMO) system; and correcting a subsequent signal in the respective radio frequency links by using the set of pre-distortion vectors corresponding to that radio frequency link. With the present invention, it is only required to scan a frame header once to generate an error vector table for the input signal across the entire dynamic range of power. The device can be reused by utilizing the cyclic delay frame structure, so as to achieve high linearity of a radio frequency header.
