The invention relates to a method for measuring the phasor frequency of an electric system, which comprises the following steps of: performing low-pass filtering on the original fixed time interval discrete sampling value sequence by using a limited shock response digital low-pass filter to eliminate the interference of second and more harmonic components in the original input signal; respectively calculating a real part and an imaginary part of a sampling value sequence in previous 2T0 time starting from an ith sampling value, and calculating a phase according to a formula; and calculating the corrected current high-accuracy frequency value according to a formula. The method is not interfered by the reference level fluctuation of a power supply, is also applicable when the frequencies ofmultipath phasors of the electric system, which are connected to the same analog/digital (A/D) converter, are inconsistent, and cannot be continuously influenced by a previous calculated value; meanwhile, accuracy meets the actual requirement of engineering.

The invention provides a reconfiguration processing method for the OLT (optical line terminal) end to ONU (optical network unit) end parameter configuration failure. The method comprises the following steps of: firstly planning the parameter configuration of ONUs; then polling the parameter configuration states of all ONUs once at fixed time intervals; if a parameter of configuration failure exists in one or more ONUs, reconfiguring the parameter of the corresponding ONU; if the reconfiguration is successful, ending the flow; and if the reconfiguration still fails after multiple times, turning to a parameter configuration failure processing flow. The method can solve the problem of individual parameter configuration failure in OLT end to ONU end parameter configuration in time.

The invention discloses a method for testing optical attenuation of an LED light source, which comprises the following steps of fixing the LED light source at one end inside a hollow cylinder with a black inner surface, mounting an illuminometer probe corresponding to the LED light source in a corresponding position of the cylinder, reading an illuminance value; immobilizing the LED light source, reading an illuminance value at fixed intervals, reading for many times and recording each illuminance value; calculating optical attenuation according to data read in many times. The invention has the advantages that the illuminometer can read directly, thereby avoiding incorrectness of test result caused by the test instrument; the illuminometer can be read when lights are available, thereby solving the problem of metering distance; and the cylinder with the black inner surface avoids influence of parasitic lights; after mounting, the LED light source is not moved until result is tested, thereby reducing influences of the position and the angle of the light source, the artificial reading difference as well as improving the accuracy of test.

A device (100) for storing items under vacuum in flexible and non-flexible containers. The device comprises a cover (102) adapted to define a vacuum chamber when it is moved into a closed position relative to a groove (in base 104) of the device. The device is also suitable for connection with vacuum-tight attachments for various containers whereby the containers can be hermetically evacuated. The device includes a heat sealing mechanism for sealing the flexible container and a cutting mechanism for cutting the flexible container to a desired size. The device includes a control panel for selectively operating the evacuation process and the sealing process.

The invention discloses a fixing device of a free-sliding safety wire for an inclined well and a mine car and relates to the technical field of mine equipment. The fixing device is designed for preventing the free-sliding safety wire from falling off. The free-sliding safety wire for the inclined well comprises a base, a first fixing module and a second fixing module. The first fixing module is fixed to the base and comprises a first pressing surface. The second fixing module comprises a second pressing surface, and the second fixing module is slidably connected to the base to enable the second pressing surface to abut against the first pressing surface for fixing. When the mine car is connected, through the first fixing module and the second fixing module, the safety wire is tightly clamped between the first pressing surface and the second pressing surface, the safety wire can be effectively prevented from falling off in mine car operation, and thus the accidences, such as mine car falling road and rollover, caused due to the fact that the safety rope falls off are avoided; and the fixing device is simple in structure and convenient to operate, the time for fixing can be shortened, and working efficiency is improved.

The invention provides a brewing process for Baijiu. The brewing process for the Baijiu comprises the steps of raw material selection, soaking, steaming and boiling, spreading for cooling, yeast mixing, fermentation, distillation, waste residue treatment and waste water treatment.
