Q:What is the cable for the YJV33 cable?
If there is a mutation in the target fragment, all the dideoxy-terminated fragments that are larger than a certain size corresponding to the mutant position have no wild-type system, and the rate of detection of mutations is improved for each occurrence of multiple changes in the mobility The ddF method overcomes the difficulty of SSCP analysis due to the effect of DNA length on SSCP, and produces a specific single stranded DNA by a dideoxycyclic acid to show that the DNA fragments with suitable length indicate SSCP changes
Q:What is the interface between the power interface and the hard disk?
Who have seen such a large 1000A estimate is almost 560 * 1.73 = 980A, the peak is almost the same
Q:How to determine whether the square of the cable is standard
Horizontal laying of the cable within the cable, generally do not need fixed, natural laying can be. Vertical laying section of the cable within the bridge, with the need to match the line card, the use of tied rope (multi-purpose single insulated wire) one by one fixed cable, fixed spacing should meet the requirements. According to the control cable and the power of the different layers of laying, if the power cable to be multi-layer need to have 300mm spacing (or load capacity is large enough), if it is control cable, casually laying, if the laying of power cable laying below Layer, above the laying of control cable, but not too much affect the power cable cooling. If the high-voltage cable and low-voltage cable in principle do not allow common laying.
Q:Wire and cable manufacturing process (to be detailed)?
Tell you an electrician commonly used "empirical formula": as long as the copper wire, cross-sectional area per square millimeter can be safely through the 4 - 5A rated current; in 220V single-phase circuit, the power per 1KW, the current For the 4.5A or so, in the 380V three-phase balanced circuit, the power per 1KW, the current is about 2A, the above values can be calculated using the physical formula is very close to the results, so the electrician at work, in order to Do not remember those "cumbersome" formula, remember that these can. Then according to this algorithm to know: every 1 mm square cross-sectional area of the copper wire, if used in 220V single-phase circuit, you can safely carry 1KW load through the current, if used in three-phase balanced load (such as motor) Circuit, you can safely carry 2.5KW load through the current
Q:Wire yellow and green, respectively, that line of fire or zero line
Insulated piercing clamp is mainly composed of reinforced shell, puncture blade, gasket, waterproof grease, high strength bolts, torque nut and cable terminal cap. When the cable needs to be branched or connected, the cable branch line terminal is inserted into the waterproof terminal Cap sets, to determine the main line branch position, with a socket wrench screw clamp on the torque nut, the process of contact with the blade will pierce the cable insulation, contact with the conductor, the sealing ring ring around the cable puncture position, the shell Grease overflow, when the torque reaches the set value, the nut torque mechanism off, the main line and branch line is connected, and waterproof performance and electrical effects to meet the standard requirements of the parameters. T-shaped terminal is composed of insulation base, wiring frame, fire shield composed of three parts, wiring box by the wire clip, screws, nuts and variable frame and other components, wiring clip and wire contact surface was wrapped in the shape of the dentoid staggered structure, With a large area of ​​spinous process, pressure line reliable features. Through the different shapes of the wire combination of each other, can form a double connection, the lower access to the main line, the upper access to the branch line, the formation of continuous "T" -shaped connection, the product is a protective cover, especially suitable for cable trays and cable And other small places to use, can effectively prevent the suffering of the mouse on the line.
Q:How to convert the computer's audio and video to cable TV signals. Through the cable television transmission to the 40 TV (hurry)
In general, a 42U cabinet to 200 information points within the appropriate
Q:The UV lamp is fitted with ozone and no ozone difference
Clean the copper wire to be welded, and dip a little solder paste or rosin before welding.
Q:What is the difference between a shielded cable and a control cable?
If there is a number of casing is the number of lines marked, if the line before the iron circle is a small nose, line nose in addition to a small circle and fork, and fork almost look.
Q:How long is the service life of the cable?
cable bridge and other pipes and other facilities shall not share a column (bracket)
Q:What is the difference between VV22 and VV62?
Copper core conductor PVC insulated PVC sheathed double steel tape wrapped armored type power cable copper conductor PVC insulated PVC sheathed non-magnetic metal armored power cable difference is the type of armor material
