White vinegar
The neckline of a white shirt is most prone to yellowing, and the washing powder is also not clean. Some have been placed in the closet for a long time, and have come out with an old color. At this time, it is necessary to pour a small cup of white vinegar with the laundry detergent, let it stand for 15 minutes, then wash it again, so that it will be the same as the new clothes!
2. Lemon
There are some stubborn stains, no matter how hard you try to wash, the stains are still there, what should you do? Lemon and water can help you solve it!
The lemon slices were boiled in water and the clothes were soaked in lemon water for 15 minutes. After taking it out, the clothes are not only as clean as new, but also with a burst of lemon fragrance~~~
3. Salt
In addition to seasoning, salt is a super-strong stain cleaner. Especially for the greasy meal printing, you can get it with one stroke! Cover the salt with the grease, wait for the salt to absorb the oil, then gently brush off the salt, the clothes will be completely new!
Milk
For the teacher, the student party will always encounter the situation where the clothes are painted with pens and pens. What should I do? At this time, the milk can play its role. Heat the milk and boil it, and wipe it with cotton to remove the stains on the clothes. There is also a touch of milk, with clean clothes, is there a feeling of a youth campus idol drama?
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
The last SCSI device in the SCSI chain uses a terminator, and the intermediate device does not need a terminator. Once the terminator is used by the intermediate device, the SCSI card cannot find the future SCSI device. If the last device does not use a terminator, SCSI will not work properly. Terminator is composed of resistors, located at the end of the SCSI bus, to reduce the mutual influence of the signal, maintain the constant voltage on the SCSI chain.
Most of the SCSI devices have built-in terminators and use a jumper to control on / off. The SCSI device is highly intelligent and can automatically control the terminator on / off. For example, if a hard disk is connected to a CD-ROM, the CD-ROM can work normally regardless of whether the terminator of the hard disk is on or off. However, when two hard disks are connected, the situation becomes more complicated. Before two Seagate hard disks are connected, one hard disk terminator must be off. Before a Seagate hard disk is connected to a quantum hard disk, a hard disk terminator can work normally regardless of whether it is on or off.
