    摘要： A continuous trawl fishing method includes: by dragging a fishing net in water through a vessel, carrying out trawling operation so that catches to be fished enter a cod-end of a fishing net tail; then tractioning and moving the cod-end so that a sucking fish tube of a vacuum sucking fish pump reaches into the cod-end; and a tube mouth of the sucking fish tube contacting the catches in the cod-end to run the vacuum sucking fish pump to suck the catches from the cod-end into the collection tank through the sucking fish tube, and the catches in the collection tank being then transferred and frozen or directly processed. The fished catches of the present invention are obviously improved in indicators such as the stiffness time and the number of the first-grade fresh fish and so on. The histamine content is obviously reduced and the catch quality is improved.

    摘要： A device and a process for producing undecylenic acid methyl ester using methyl ricinoleate as raw material are provided. The device comprises a feed pump, a raw material pre-heater, a microwave catalytic reactor, a microwave generator, a temperature controller and an infrared sensor, a condenser, a product tank and a discharge pump. The feed pump is connected with the raw material pre-heater, which is connected with the inlet of the microwave catalytic reactor. The outlet of the microwave catalytic reactor is connected with the condenser, which is connected to the product tank and the discharge pump. The microwave catalytic reactor is located in the microwave generator, which is connected with the temperature controller and the infrared sensor. The process is as follows: high-purity methyl ricinoleate, used as the raw material, is converted to methyl undecene and heptaldehyde by microwave-assisted pyrolysis process, followed by isolation and purification to produce methyl undecene.
