3results about How to "Reduce testing workload" patented technology

The application discloses an operating mechanism data acquisition system and a driving loop module and method thereof, and the module comprises a high-voltage direct-current power supply HM, a high-voltage direct-current power supply KM, a power adapter DP, an embedded control module QK, a control switching plug HT, a supply and discharge circuit, a closing and opening knob KK and a rotary switch ZH2; the high-voltage direct-current power supply HM provides an energy storage power supply and a closing power supply for a measured operating mechanism, the high-voltage direct-current power supply KM provides an opening power supply for the measured operating mechanism, the power adapter DP provides a working power supply for the embedded control module QK, and the required operating power supply voltage for testing can be met; the embedded control module QK can realize program control of driving, the rotary switch ZH2 can realize mode conversion between manual control and program control of driving, and the closing and opening knob KK can realize manual control of driving, so that the problem that traditional operating mechanism research experiments cannot simultaneously integrate automatic control of multiple characteristic parameters is solved.

This disclosure relates to a flat-panel satellite, including a cabin. The cabin is generally a flat rectangular body. The cabin includes a first, second, third, fourth, fifth, and sixth cabin panel that are detachably arranged to form a compartment. Different functional systems are respectively installed on the first, second, third, fourth, fifth, and sixth cabin panels. These functional systems include: a payload antenna system, with the payload antenna integrated on the outer side of the first cabin panel; and a platform control system, located inside the cabin and integrated on the inner side of the second cabin panel. This disclosure eliminates the complex support structure of traditional flat-panel satellite payload antennas by making the cabin panels detachably connected and integrating the payload antenna onto one of the cabin panels. The modular design reduces the integration difficulty of the flat-panel satellite, shortens the production cycle, and reduces testing workload and costs.

The method for simultaneously determining multiple nitrophenol compounds in different food matrices according to the present invention involves preparing a series of mixed solutions with different concentrations of 2,4-dinitrophenol, 2,5-dinitrophenol, 2,6-dinitrophenol, 3,4-dinitrophenol, and 3,5-dinitrophenol using acetonitrile-acetic acid solution as standard samples; the food matrices to be tested are then subjected to extraction and purification treatment. The sample was obtained through a process; then, high-performance liquid chromatography-tandem mass spectrometry was used to detect the sample and standard to obtain the concentrations of 2,4-dinitrophenol, 2,5-dinitrophenol, 2,6-dinitrophenol, 3,4-dinitrophenol, and 3,5-dinitrophenol in the sample. The content of each nitrophenol compound in the food matrix was then calculated based on the concentrations of 2,4-dinitrophenol, 2,5-dinitrophenol, 2,6-dinitrophenol, 3,4-dinitrophenol, and 3,5-dinitrophenol in the sample.
