The power supply comprises a voltage source and at least one current source which are connected in parallel; the control ends of the voltage source and the current source are simultaneously connected with the processor, and the processor receives a control signal; and the output ends of the voltage source and the current source are simultaneously connected with two ends of the silicon controlled switch circuit. The invention adopts a multistage parallel power supply mode when supplying power for a load requiring large current power supply by arranging the controllable parallel circuit of the voltage source and the current source, and can arbitrarily control the output power of any path. And each path of the voltage source and the current source which are connected in parallel is provided with an independent output interface, and when necessary, any path of voltage source and current source is merged into the total output port by controlling the silicon controlled switch circuit to increase power output, or the number of the parallel branches of the total output port is disconnected to reduce power output.

摘要：【中文】本申请实施例提供了一种非均质油层的堵水工艺及其应用，属于油田封堵技术领域。本申请实施例提供的非均质油层的堵水工艺，通过将油管下至目标采油井射孔段的上部，向目标采油井注入第一堵剂和第二堵剂，通过第一堵剂封堵目标采油井的远井地带，通过第二堵剂封堵目标采油井的近井地带，待第一堵剂和第二堵剂凝固后，在目标采油井油层顶部射孔，穿透近井地带的封堵带，开采目标采油井油层中的剩余油。其中，所述第一堵剂和所述第二堵剂均为自固结材料。该工艺中使用的第一堵剂和第二堵剂均为自固结材料，封堵强度高，有效期长，封堵效率高，从而封堵非均质厚油层底部的水层，降低油井的含水率，提高产油量，进一步提高经济效益。 【EN】The embodiment of the application provides a water plugging process of a heterogeneous oil layer and application thereof, belonging to the technical field of oil field plugging. According to the water plugging process of the heterogeneous oil layer, the oil pipe is lowered to the upper portion of the perforation section of the target oil production well, the first plugging agent and the second plugging agent are injected into the target oil production well, the far wellbore zone of the target oil production well is plugged through the first plugging agent, the near wellbore zone of the target oil production well is plugged through the second plugging agent, after the first plugging agent and the second plugging agent are solidified, perforation is conducted at the top of the oil layer of the target oil production well, the plugging zone of the near wellbore zone is penetrated, and residual oil in the oil layer of the target oil production well is exploited. Wherein the first plugging agent and the second plugging agent are both self-consolidation materials. The first plugging agent and the second plugging agent used in the process are self-solidifying materials, so that the plugging strength is high, the effective period is long, and the plugging efficiency is high, thereby plugging the water layer at the bottom of the heterogeneous thick oil layer, reducing the water content of the oil well, improving the oil yield and further improving the economic benefit.

摘要：【中文】本发明公开了一种北方旱地马铃薯艺机一体化栽培方法，其在播种前20天，将切割有若干个V形切口的种薯置于添加有月光花素和高锰酸钾的浸种剂内浸泡后，捞出，用纱布包裹，置于散射光暖房内催芽，催芽完成后，采用经经高锰酸钾溶液浸泡后的刀具将种薯切分成若干薯块，在薯块表面喷涂一层10%苯醚甲环唑1000倍液，阴干；选用集开沟、施肥、播种、镇压、覆膜、覆土作业为一体的双行马铃薯种植机进行播种，播种时将种薯种块和化肥颗粒同时播种在不同深度的土壤内，并使得化肥颗粒播在种薯薯块的左侧方、右侧方、前侧方和后侧方一定的距离处，且相邻两个种薯薯块四个侧面的化肥颗粒错开设置。本发明实现了马铃薯的稳产、丰产。 【EN】The invention discloses an integrated cultivation method of potatoes in northern dry land by an art machine, which comprises the steps of soaking seed potatoes cut with a plurality of V-shaped cuts in a seed soaking agent added with moonlight essence and potassium permanganate 20 days before sowing, fishing out, wrapping with gauze, placing in a scattered light greenhouse for accelerating germination, cutting the seed potatoes into a plurality of potato blocks by a cutter soaked by potassium permanganate solution after accelerating germination, spraying a layer of 10% difenoconazole 1000 times solution on the surfaces of the potato blocks, and drying in the shade; choose for use and collect ditching, fertilization, seeding, suppression, tectorial membrane, earthing operation double-row potato planter as an organic whole to sow, sow seed potato seed block and chemical fertilizer granule simultaneously in the soil of the different degree of depth during the seeding to make the chemical fertilizer granule broadcast in the left side of seed potato piece, right side, front side and certain distance department of posterolateral, and the setting of staggering of chemical fertilizer granule of four sides of two adjacent seed potato pieces. The invention realizes the stable and high yield of the potatoes.
