The invention discloses a liquid crystal injection method, comprising the following steps of: step a, closing the cabin door of a liquid crystal injection machine when a liquid crystal container is filled with liquid crystal, and then implementing step b, wherein the liquid crystal container is arranged on a base within a cavity of the liquid crystal injection machine, the liquid crystal container is equipped, in an insertion manner, with a liquid crystal heater controlled by an electric control system and a liquid crystal temperature controller which is used for feeding back liquid crystal temperature collected in real time to the electric control system to form a closed loop control; step b, removing air from the liquid crystal, then opening the cabin door and implementing step c; and step c, placing a roasted display panel on a bracket which is arranged within the cavity, and then closing the cabin door to complete the steps for injecting liquid crystal into the display panel. The liquid crystal injection method provided by the invention has the advantages that the heating structure of the liquid crystal container is simple and practical, the temperature of the liquid crystal can be accurately monitored, the viscosity of the liquid crystal is reduced to the largest extent while preventing the volatilization of low-boiling point component in the liquid crystal, and the consumption of the liquid crystal and the rejection rate of the product are reduced.

The invention provides a die temperature control system and method, belongs to the technical field of dies, and solves the problem of non-uniform temperature field of the conventional die. The die temperature control system is arranged on heating circuit of heating pipes and comprises a power supply for supplying power, a plurality of temperature detection devices for detecting the temperature, one or more than one temperature acquirer connected with the temperature detection devices, and a multi-channel temperature controller which is connected with each temperature acquirer and a plurality of heating pipes and is used for controlling the heating temperature of the heating pipes, wherein each heating pipe corresponds to at least two temperature detection devices. According to the control method, the average temperature of the heating pipes is compared with standard temperature, and then single-point temperature of a die cavity is compared with the standard temperature. By the die temperature control system and method, the die can be quickly and uniformly heated.

The invention provides an in-situ solar thermal desorption repair system for polluted soil, which belongs to the technical field of polluted soil repair, and includes a support frame, a heat collecting tube, a heat collecting cover, a reflector, an air supply part, an air injection pipe and an air extraction pipe; The heat collecting tube is rotatably installed on the support frame, and the outer side of the heat collecting tube is provided with a spiral piece; the heat collecting cover is installed on the support frame and sleeved on the outside of the heat collecting tube; the waste gas for the passage of exhaust gas is formed between the heat collecting tube and the heat collecting cover channel; the reflector is used to reflect sunlight to the collector tube. The in-situ solar thermal desorption repair system for contaminated soil provided by the present invention uses solar energy to heat the gas, reducing energy consumption; when the waste gas generated by thermal desorption passes through the waste gas channel, it exchanges heat with the gas in the heat collecting tube, and utilizes the waste gas The heat in the heat collecting tube reheats the gas in the heat collecting tube, which not only improves the utilization rate of energy, reduces energy loss, but also improves the heating efficiency of the gas in the heat collecting tube.

The invention discloses an energy saving and consumption reduction adjuster capable of achieving fine watering adjustment and well washing control and relates to the field of oilfield water injectionvalves. The adjuster comprises a valve body and two valve components, wherein the valve components are mounted on the valve body and comprise valve rods, valve plugs and valve seats; the valve plugs are driven by the valve rods to be close to or far away from the valve seats to achieve opening and closing of the valve components; an outer profile of the valve body is in a cubic structure; a waterinlet pipe and a water outlet pipe are arranged on the outer side of the valve body; the two valve components have the same structure but are different in size; and the two valve components are mounted in two mounting holes in the valve body. According to the adjuster, a main channel and an auxiliary channel are arranged in the valve body; the coarse adjustment valve component arranged on the mainchannel can coarsely adjust watering quantity; the fine adjustment valve component arranged on the auxiliary channel can perform fine adjustment on the watering quantity; step-by-step coarse and fineadjustment is achieved; and therefore, the adjustment accuracy of a watering valve is further improved.

The invention relates to a method of testing the no volatilized residuum and the relative carbon amount in the solid test specimen, puts the test specimen into the heat-resisting vessel and under the isolation air condition after separately heats the certain time with the heater in the 750-850 deg,950-1050 deg, 1050-1150 deg three temperature areas weighing and computing the no volatilized residuum and the relative carbon amount according to the following formula; the method has good isolation effect with air and the long heat time, can fully drive out the volatile matter but not to affect the residuum character, the three temperature areas tubular heat up structure is simple, operation simple bright and is easy to make the processing, the observation data reduction mathematical formula simply, is easy to grasp, the test entire process and the atmosphere even more approach the stove return original state process of the electric heating to smelt the aluminum silicon alloy, the obtainedresult has a better instruction.
