A distributed radar includes a control unit, a receive antenna, and N transmit antennas. The N transmit antennas include a first transmit antenna, a second transmit antenna, and a third transmit antenna. There are a first distance between the first transmit antenna and the second transmit antenna, and a second distance between the first transmit antenna and the third transmit antenna, and the first distance is shorter than the second distance. The second transmit antenna is connected to the control unit by using a first cable, the third transmit antenna is connected to the control unit by using a second cable, a ratio of the first distance to the second distance is a first ratio, a ratio of a length of the first cable to a length of the second cable is a second ratio, and the second ratio is greater than the first ratio.

A method includes configuring a preset reference pulse number, and controlling a test contact piece for testing chip leads to move toward a target chip lead, using a control signal corresponding to the preset reference pulse number. First data is continuously obtained and used to determine whether the test contact piece is in contact with the target chip lead. When the test contact piece is in contact with the target chip lead, the test contact piece is controlled to stop moving. Second data is obtained characterizing movement of the test contact piece from a time when the test contact piece initially contacts the target chip lead to a time when the test contact piece stops moving. The preset reference pulse number is adjusted based on the second data. A system and device, and a computer-readable storage medium are also provided for implementing the method.

A 3D-configured production structure of rubber products based on an intelligent manufacturing unit and a production method thereof. The structure includes a stereoscopic production warehouse used to store a mobile intelligent manufacturing unit and an ex-warehouse delivery system used to deliver the mobile intelligent manufacturing unit. The mobile intelligent manufacturing unit includes a unit functional assembly, a molding vulcanization apparatus, a blank feeder, a material-delivering apparatus, a product-collecting apparatus and a reclaimer. The molding vulcanization apparatus includes a upper heat plate, a upper mold, a lower mold, a lower heat plate and a support post. The upper mold and the lower mold are arranged on the inner sides of the upper heat plate and the lower heat plate, respectively. The upper heat plate is fixed on one end of the support post, and the lower heat plate is arranged through the support post.

The invention provides a suspension modifier directly added into fracturing fluid for real-time proppant modification during fracturing and the application thereof, relating to the field of oil and gas production technologies. The suspension modifier is a controlled release nanoemulsion and comprises surface hydrophobic modifier, surfactant, cosurfactant and water. The suspension modifier is directly added into clear-water or active-water fracturing fluid while the proppant is added into water. After stirring, the suspension modifier is capable of self-assembling and being adsorbed on the proppant surface, so that the proppant surface becomes hydrophobic and aerophilic. The invention no longer requires the proppant to be pretreated, and the bubble-suspended proppant can be obtained directly by adding the suspension modifier to the clear-water or active-water fracturing fluid, and meanwhile adding the proppant to the fracturing fluid. This technology is not only easy to operate, but also low in cost for proppant treatment.
