1, Ois is the operator interface station, which is the man-machine interface. An operating system. Through data collection, storage, transmission, management and processing, office information system provides information services for office workers, improves office efficiency and office quality, and thus obtains economic and social benefits.

2.OIS (Organic Internet System) is an organic Internet ecosystem, which is different from the traditional internet plus. It is no longer a simple interconnection between the Internet and entities, but an organic Internet ecosystem based on a strong trust mechanism and security system, which organically integrates the Internet and entities and makes people's needs and supplies interdependent.

3.ois is the abbreviation of optical image stabilizer, namely optical image stabilizer. Its function is to correct the "optical axis deviation" through the floating lens of the lens.

The principle is that the tiny movement is detected by the gyroscope in the lens, and then the signal is transmitted to the microprocessor, and the processor immediately calculates the displacement to be compensated, and then compensates according to the shaking direction and displacement of the lens through the compensation lens group; So as to effectively overcome the image blur caused by camera vibration.

4. OIS (Obstacle Recognition Surface)

Obstacle discrimination surface is a group of inclined planes built around the airport, which are used to identify obstacles. The slope of the inclined planes is 2.5%. When an obstacle passes through the OIS plane, it is necessary to specify a flight path in the departure procedure in order to avoid the obstacle safely. Or specify the minimum net ascending gradient (Gr) to provide appropriate redundancy when flying over these obstacles.

5. OIS (overnight index swap)

Overnight Index Swap (OIS) is an interest rate swap that converts overnight rate into several fixed interest rates.
