quark    音标拼音: [kw'ɑrk]
n. 一种假设的素粒子

一种假设的素粒子

quark
n 1: (physics) hypothetical truly fundamental particle in mesons
and baryons; there are supposed to be six flavors of quarks
(and their antiquarks), which come in pairs; each has an
electric charge of 2/3 or -1/3; "quarks have not been
observed directly but theoretical predictions based on
their existence have been confirmed experimentally"
2: fresh unripened cheese of a smooth texture made from
pasteurized milk, a starter, and rennet [synonym: {quark cheese},
{quark}]

  • Whats inside a quark? | Questions | Naked Scientists
    Chris - So could these things be sitting in some other bizarre dimension that we see it in the dimensions that we're familiar with interacting with, but there are other dimensions that we can't see, they're hidden from us let's say And that's where actually the thing that gives the quark its existence is sitting
  • HOW DOES AN UP QUARK TURN INTO A DOWN QUARK?
    An imaginary picture of the hydrogen atom, the proton is composed of two red up quarks and one blue down quark with the electron being a yellow point What do you suppose the code is that mixes the electron with one of the red quarks turning into a blue quark and thus a neutron?
  • What do strange quarks do? | Naked Science Forum - The Naked Scientists
    A quark is a fast-moving point of energy There are several varieties of quarks Protons and neutrons are composed of two types: up quarks and down quarks Each up quark has a charge of +2 3 Each down quark has a charge of -1 3 The sum of the charges of quarks that make up a nuclear particle determines its electrical charge
  • Tetraquarks: new configurations of subatomic particles discovered
    Harry - Very simply a tetraquark is a particle made of two quarks and two antiquarks So, sort of four objects inside it basically, hence the tetra It probably requires a bit of unpacking though, because well, you might ask what's a quark? Well, every atom has a nucleus, and you probably know that the nucleus is made of protons and neutrons
  • Why do quarks, last less time, outside the composites particles they . . .
    We will also add EM force and energy The original particle composite, upon collusion, will be the original particle composites, plus relativistic mass and EM induction This may add a quark or two that may only exist under these unique lab conditions This intermediate and unstable state could explain the short life
  • How the Higgs Boson was theorised | Interviews
    Lyn - Well, the latter part of the 1960s was a mess It was more like a whole zoo of particles being discovered all the time
  • Whats the smallest particle we can detect? | Science Questions
    In that case, something like a quark, which is the constituent of a proton or a neutron - very, very very, tiny I’m going to quote John Butterworth, who’s a Professor at UCL, who said “it’s about 43 billion billionths of a centimetre ” So absolutely incredibly tiny
  • If black holes stops time does white hole accelerate time?
    It is highly unlikely that gravity is the force that would drive a white hole More likely a critical density is reached within the confines of a black hole where the electromagnetic forces overcome gravitation for some as yet unknown reason It could be an imbalance in the distribution of quark charge
  • How do we measure the energy of a photon?
    ' Define the Quark class that inherits from Particle Public Class Quark Inherits Particle Public Property Type As String Public Sub New(type As String, charge As Double, mass As Double) MyBase New(False, charge, 1 2, mass) ' Example spin value for a quark Me Type = type End Sub End Class ' Define specific quark types Public Class UpQuark
  • Structure of electrons, quarks and gluons; preon, preons
    The bonds of particles from the galactic model and higher models are probably - like quark-gluon bonds - indecomposable All particles from the galactical model are somehow related to the main particle of the model, which is related to the rotation of the galaxy where the center is a supermassive black hole (black star)
