帮看看英语作文有误病句～16
The utility model relates to a paraffin separating tank ,which belongs to chemical equipment. An upper and a lower pattern boards are welded in the tank, and tube orifices used for welding the vertical tubes are arranged on the pattern boards. Each vertical tube is welded with the orifice of the pattern board. Net boards are arranged at the middle part and the lower part of the tank body. An external heating case is welded on the outside of the tank.The tank body is provided with an upper and a lower view mirrors, material inlet and outlet ports, water inlet and outlet ports and a thermometer. The utility model has the advantages that the cost is low, the temperature difference between the center and the edge of the tank is little and the separation of the wax oil is complete. [#89205935#] The utility model relates to an intelligent on-line multi-test electric meter, mainly solving the problem of the on-line testing of printed circuit boards. The utility model comprises a monolithic system 1, a transistor testing circuit 2, an on-line resistor/voltage conversion circuit 3, an on-line electric current/voltage conversion circuit4, an AC/DC voltage conversion circuit 5, a voltage divider and buffer 6, a function button and multi-way switch 7, a range-changing switch 8, a modulo/digital converter 9, a digital display 10, an interface expander 11, a stabilized power supply 12, etc. The utility model can test the resistor or the current of the printed board directly ,and can judge accurately whether the diode and the triode which are on the board are intact.

Answer 1

The utility model relates to a temperature controlled switch, comprising a thermal dual-metal sheet, an adjusting mechanism and a set of electrical contacts. The utility model is characterized in that the electrical contacts are normally open, and the contacts convert original off-state into on-state when the temperature of the thermal dual-metal which is heated goes up to the designated value. With an acoustic device,an acousto-optical device or a corresponding acting device, the utility model can be used for temperature control alarming, dangerous alarming or security protection and energy-saving operation for the heating device, the cooker which is heated or the water and food in the cooker, under the situation of various thermal sources such as electricity, coal , firewood, gas, oil, etc. The utility model has the advantages of simple structure ,low cost, convenience use ,and high efficiency . [#89209324#] The utility model relates to a safety power saving lighting lamp for machine tool aperation, comprising a universal ball lamp socket (1), a laminated board(2), a universal ball (5), a flexible snake skin lampholder(6), electric wires (7)and(8), a lamp cap(13), a transformer B-[1], full-bridge rectifiers D-[1]～D-[4], a capacitor C-[1] and a trichromatic fluorescent lamp. Instead of a 60w bulb,a 9w trichromatic fluorescent lamp is arranged on the utility model,saving 80% power.Compared with the existing lighting lamp for machine tool aperation ,the service life of the utility model increases to 7 times , and the light is softer . With a 10w power transformer, the loss is less .
