1. Yingtai tb250-btc is a B250 chipset, which can only use DDR4 memory, and does not support ddr31600
to play CF underground city, you'd better change to a better CPU. You can use g4560, because the performance of g4400 is too poor
2. First of all, untie all the wechat cards. Second, take out or transfer all the wechat change to relatives (parents, wife, parents), First of all, wechat payment requires a password. Secondly, there is no trojan virus that can bypass the password lock of wechat. That's big prime. The difficulty of dismantling big prime is no less than that of digging
bitcoin with
mining machine, Moreover, bitcoin is limited, and wechat password is unlimited. In principle, if you want to dect your money without entering a password, you must turn on automatic renewal. First, check yourself from this perspective, and then consider whether it is stolen or something else. Because the possibility of number theft is too low. First of all, although wechat can log in more frequently on the computer through technical means, one thing you can't avoid is login verification. Secondly, when wechat locks the machine code of the mobile phone, in principle, if you don't log in on the computer, a single mobile phone can only log in to the current account, Mobile phones can also be opened more, but the nature is different. I won't discuss it here. Therefore, the difficulty of number theft is no less than solving Goldbach's conjecture. You first check whether you have misoperation, and then check whether the automatic renewal in the management has opened anything strange. Finally, if you check yourself and find nothing... I suggest you call the police to deal with it. At least you can find out who the phone numbers are through the police
3. Installation of ant protection board app, only support Android protection board calibration:
1. Unit voltage calibration: by adjusting the "system reference voltage" (about 3.0 by default), slowly increase and decrease the amplitude of 0.001, the unit voltage value can be changed until it is accurate! 2. Total voltage calibration: by adjusting the "total voltage ad value into the actual voltage of the parameters" (default about 3330), slowly adjust the size of this value, you can change the total voltage until accurate! 3. Current calibration: by adjusting the "current sensor range", slowly adjust the value, you can change the current until it is accurate
note: please do not change the item of "power starting current" in parameter setting, too large may lead to MOS tube burning and discharging!!!

8. On August 15, 1945, after the unconditional surrender of the Japanese aggressors, the Soviet army arrived in Anshan on August 26. From late September to early November 1945, in just over 40 days, the Soviet Red Army detained tens of thousands of Japanese prisoners of war and dismantled and transported more than 70000 tons of Angang's mechanical equipment and other materials. Especially after some key equipment was stolen, the entire instrial proction capacity dropped to zero, and the damage was extremely serious. In addition, after the withdrawal of the Soviet army from Anshan, the social order was chaotic. Some residents took the opportunity to dismantle and take away part of the transport belts, balls, grease, small motors and wires of Angang, which also caused some losses
according to the investigation report of the KMT Resources Committee, most of the intact parts of the original equipment of Angang were relocated to the steel plants in Magnitogorsk and Chelyabinsk of the Soviet Union. Some defective equipment damaged ring demolition is missing, and it is estimated that it has been recycled or scrapped. 1、 Mining equipment:
70% of the crushing equipment, all the air compressors, all the cone crushers, all the locomotives, 60% of the freight cars and all the trucks in Gongchangling mine
Dagushan mine has all the mining equipment with an annual capacity of 7 million tons, all the German Sherman electric prospecting machinery, all the locomotives and all the freight cars< Second, mineral processing equipment:
all mineral processing equipment with an annual output of 850000 tons, all ball mills, 50% tube mills, all magnetic concentrators, all sintering equipment
Third, granular iron equipment:
all machinery and equipment of granular iron plant with an annual output of 180000 tons of sponge iron
Fourth, ironmaking equipment:
all detachable parts of No Cooling equipment, charging car, balance car, bell hoist, raise crane, st collector, casting crane, coke crane, hot blast stove. All of them are imported from Germany, Japan and the United States. In addition, 6 gantry cranes and 3 cast iron machines were dismantled< 5. Coking equipment:
all auxiliary equipment and machinery of No.11 to No.18 coke ovens; (6) coal washing equipment:
70% of 150 ton coal washing equipment and all of 200 ton coal washing equipment; (7) chemical equipment:
all of benzene refining plant, naphthalene plant, sulfuric acid plant and ammonium sulfate plant; (8) steel making equipment:
all of mechanical equipment of No.2 steel making plant with an annual output of 750000 tons; 9. Ferroalloy equipment:
one 15 ton electric furnace, two 6-ton electric furnaces and all supporting mechanical equipment
10. Steel rolling equipment:
a complete set of equipment for the second blooming mill with an annual output of 500000 tons; 200000 tons of large-scale plant all equipment; 150000 tons of medium plate plant equipment; All equipment of the second small plant with 100000 tons; 11. Power equipment:
a set of 25000kw and 18000kw generator sets respectively; Six high-pressure boilers and eight high-pressure forced draft fans
12. Machine tools:
64% of main machine tools
13. Research machinery and equipment:
all research machinery and equipment
other machinery:
total weight 45000 tons
manufacturing and processing machinery:
all equipment of Sumitomo Metal Instry Association and Kubota cast iron pipe Association
in general, The loss of each plant is more than half, while the loss of mineral processing, steelmaking and rolling is more than 70%. Because a large number of mechanical equipment was removed, the power equipment stopped completely, and the proction operation of Angang was completely paralyzed. In terms of steel rolling, only the medium-sized plant of Anshan Steel Association and the medium and heavy plate plant of Dagu heavy instry association are less damaged and can be used reluctantly. Other factories, such as Manchuria wire netting plant and Manchuria zinc plating plant, were not fatally damaged, but they were unable to proce because the second small factory was completely demolished and had no raw materials. The large-scale factories procing heavy rail and the factories procing seamless steel pipes and thin plates have all been dismantled. Therefore, at that time, such a large iron and steel complex could not even proce iron wire and nails. Resial capacity of original capacity decreased%
