二氧化碳是植物光合作用的主要碳源，可以用作植物溫室的氣體肥料和水草缸水族箱的肥料。
Aerodynamics is connected to the movement of air about a projectile, which can influence the velocity and route of the item. For objects in water, it is known as hydrodynamics.
二氧化碳可控制pH值，游泳池加入二氧化碳以控制pH值，加入二氧化碳從而保持pH值不上升。
These signs may well issue to lung dysfunction involving the Trade between oxygen and carbon dioxide.
The narrow-system efforts led towards the launch on the A320 in 1987, which was and proceeds to be a major commercial success. The A320 was the very first professional jet to use a electronic fly-by-wire Manage program. All Airbus aircraft produced considering the fact that then have cockpit methods similar to the A320, which makes it simpler to coach crew.

By the time the audio barrier was damaged, aerodynamicists' understanding of the subsonic and low supersonic stream had matured. The Cold War prompted the look of an ever-evolving line of superior-effectiveness aircraft. Computational fluid dynamics began as an exertion to unravel for circulation Attributes close to elaborate objects and it has quickly developed to The purpose where by overall aircraft is usually developed employing computer program, with wind-tunnel exams followed by flight exams to confirm the computer predictions. Comprehension of supersonic and aerodynamicss hypersonic aerodynamics has matured Considering that the nineteen sixties, plus the goals of aerodynamicists have shifted from your behaviour of fluid flow into the engineering of the auto these types of that it interacts predictably With all the fluid flow.
or log in to an existing account Have the FlightAware Application for the most beneficial flight tracking encounter in your gadget.
The word emanates from two Greek words and phrases: aerios, concerning the air, and dynamis, meaning force. Aerodynamics is definitely the review of forces as well as the ensuing motion of objects from the air.
Subsonic (or minimal-speed) aerodynamics describes fluid motion in flows that happen to be A great deal reduce compared to velocity of seem everywhere you go in the flow. There are lots of branches of subsonic stream but a person Distinctive circumstance occurs if the flow is inviscid, incompressible and irrotational.
