n. 肺气肿

肺气肿

emphysema
n 1: an abnormal condition of the lungs marked by decreased
respiratory function; associated with smoking or chronic
bronchitis or old age [synonym: {emphysema}, {pulmonary
emphysema}]

Emphysema \Em`phy*se"ma\, n. [NL., from Gr. ? inflation, fr. ?
to inflate; ? in ? to blow: cf. F. emphys[`e]me.] (Med.)
A swelling produced by gas or air diffused in the cellular
tissue.
[1913 Webster]

{Emphysema of the lungs}, {Pulmonary emphysema} (Med.), a
common disease of the lungs in which the air cells are
distended and their partition walls ruptured by an
abnormal pressure of the air contained in them.
[1913 Webster]

  • Speed of Light - BYJUS
    Speed of Light The velocity of the light in the vacuum or air: The speed of light c = 299792458 m s ≅ 3 × 108 m s The velocity of light can be expressed in terms of mph or km s That is- The speed of light in mph 186,000 miles per hour The speed of light in air is 299792 km s
  • How Fast is the Speed of Light? | Facts, Information, Anything Faster?
    In water, the speed of light is slower, at 225,000 km 139,808 mi per second, and 200,000 km 124,274 mi per second in glass It seems that nothing can be faster than the speed of light
  • Speed of Light | Facts, Information, History Definition
    The speed of light’s exact value is defined as 299 792 458 meters per second or approximately 300 000 km 186 000 mi per second in a vacuum
  • What are the Properties of Light? - BYJUS
    Following are the important properties of light – Light travels in a straight line The speed of light is faster than sound Light travels at a speed of 3 x 10 8 m s Reflection of light Reflection is the phenomenon in which light travelling in one medium, incident on the surface of another returns to the first medium, obeying the laws of
  • What Is Wavelength? - BYJUS
    What Is Wavelength? The wavelength of light is defined as “The distance between the two successive crests or troughs of the light wave” It is denoted by the Greek letter lambda (λ) Therefore, the distance between either one crest or trough of one wave and the next wave is known as wavelength
  • What Is Refractive Index? - BYJUS
    The ratio between the speed of light in medium to speed in a vacuum is the refractive index When light travels in a medium other than the vacuum, the atoms of that medium continually absorb and re-emit the particles of light, slowing down the speed light In this article, let us discuss the r efractive index of water and various mediums
  • What Is Refraction? - BYJUS
    What Is Refraction? Refraction of Light is a phenomenon wherein light bends and travels from one transparent substance to another Let’s understand this concept in-depth with an illustration So, have you ever observed the bottom of a thick glass slab when a printed paper is kept below it? You will find that the printed matter seems to be raised Similarly, when a pencil is partly immersed in water in a glass tumbler, it appears to be displaced from its original position at the surface
  • What is Frequency? - BYJUS
    The wave speed is equal to the product of its frequency and wavelength, and this implies the relationship between frequency and wavelength Learn the relationship between velocity and wavelength and the relationship between amplitude and frequency by clicking on the links below:
  • What Are Electromagnetic Waves? - BYJUS
    What is the wavelength of the photon of infrared light with the frequency 2 5 x 10 14 Hz? Since infrared light is a part of electromagnetic spectrum, the relation between the wavelength, frequency, and velocity is given by the formula: \ (\begin {array} {l}c=f\lambda\end {array} \) Consider c = 3 x 10 8 m s -1
  • What is a Light Year? - BYJUS
    Light travels at 186,000 miles or 300,000 kilometres per second in an empty space To give you a simple idea of how fast this is, light can travel around the Earth seven times in just one second! Astronomers use the speed of light to determine how far away objects are in space The distance that light can travel in one year is measured in light-years (ly)
