    Cheque reversal means that you go directly to the payer's bank and ask for the money to be transferred to the payee's bank. In this way, it is not very convenient for you, and you have to find his opening bank, that is, someone else gives you a check, and the payee is you, and you do not deposit in your opening bank, but go to his opening bank to ask for a reverse deposit. The reverse deposit will arrive in the morning and the account in the morning, and the afternoon deposit will arrive in the afternoon, which is half a day faster than the regular deposit.

    In fact, the paying bank directly transfers the money to the beneficiary bank.

    Sending is also depositing, this kind of much, because you generally go to your nearest bank to open an account, you take the check to your bank to deposit the check, your bank needs to hand over the check to the payer's bank through a special person in the exchange place (in the People's Bank of China), and the payer's bank will transfer money to your bank, one more time to transmit the ticket, so it is half a day slow.

    There are 4 types: 1).The column position is empty, which is a global label that indicates that the data is being called from the entire database. Like what.

    2).The column position is a specific value, which means that the data is called from the column with the ID number of that value. Like what.

    3).The position of the column is the variable $catid, which means that with the different columns, the label calls the content according to the different column ID numbers.

    Like what. 4).The position of the column is the variable $cid, which means that with the different sub-columns, the label calls the content according to the ID number of different sub-columns.

The working principle of electromagnetic relaysElectromagnetic relays are generally composed of iron cores, coils, armatures, contact reeds, etc. As long as a certain voltage is added to both ends of the first circle, a certain current will flow through the coil, resulting in an electromagnetic effect, and the armature will overcome the tensile force of the return spring under the action of electromagnetic force attraction to attract the core, thereby driving the dynamic contact of the armature to engage with the static contact (normally open contact). When the coil is de-energized, the electromagnetic suction force disappears, and the armature returns to its original position under the reaction force of the spring, so that the moving contact engages with the original static contact (normally closed contact). >>>More
