| 例句 | A white dwarf is supported by the exclusion principle repulsion between the electrons in its matter. A Brief History of Time: And Other Essays 1988-01-01T00:00:00Z Discovered in the mid-1920s by German physicist Wolfgang Pauli, the exclusion principle states, roughly, that no two things can be in the same place at the same time. Zero: The Biography of a Dangerous Idea 2000-02-07T00:00:00Z A quantum-mechanical law called the Pauli exclusion principle keeps matter from squishing itself into a point. Zero: The Biography of a Dangerous Idea 2000-02-07T00:00:00Z The idea was this: when the star becomes small, the matter particles get very near each other, and so according to the Pauli exclusion principle, they must have very different velocities. A Brief History of Time: And Other Essays 1988-01-01T00:00:00Z Pauli’s exclusion principle says that two similar particles cannot exist in the same state; that is, they cannot have both the same position and the same velocity, within the limits given by the uncertainty principle. A Brief History of Time: And Other Essays 1988-01-01T00:00:00Z The matter particles obey what is called Pauli’s exclusion principle. A Brief History of Time: And Other Essays 1988-01-01T00:00:00Z As pressure in the star increases, the exclusion principle states that electrons inside must move faster and faster to avoid one another. Zero: The Biography of a Dangerous Idea 2000-02-07T00:00:00Z If the world had been created without the exclusion principle, quarks would not form separate, well-defined protons and neutrons. A Brief History of Time: And Other Essays 1988-01-01T00:00:00Z Chandrasekhar realized, however, that there is a limit to the repulsion that the exclusion principle can provide. A Brief History of Time: And Other Essays 1988-01-01T00:00:00Z It is an important property of the force-carrying particles that they do not obey the exclusion principle. A Brief History of Time: And Other Essays 1988-01-01T00:00:00Z Chandrasekhar showed that a collapsing star that has about 1.4 times the mass of our sun will have enough gravity to overwhelm the Pauli exclusion principle. Zero: The Biography of a Dangerous Idea 2000-02-07T00:00:00Z This means that when the star got sufficiently dense, the repulsion caused by the exclusion principle would be less than the attraction of gravity. A Brief History of Time: And Other Essays 1988-01-01T00:00:00Z These stars would be supported by the exclusion principle repulsion between neutrons and protons, rather than between electrons. A Brief History of Time: And Other Essays 1988-01-01T00:00:00Z Describe the competitive exclusion principle and its effects on competing species. Concepts of Biology 2013-04-25T00:00:00Z In the same paper where he had suggested his new two-valued number, Pauli had also suggested an “exclusion principle,” the notion that no two electrons could occupy the exact same state. Quantum Particles Aren’t Spinning. So Where Does Their Spin Come From? 2022-11-22T05:00:00Z The Pauli exclusion principle is extremely powerful and very broadly applicable. College Physics for AP Courses 2015-08-12T00:00:00Z The Pauli exclusion principle can be formulated as follows: No two electrons in the same atom can have exactly the same set of all the four quantum numbers. Chemistry 2019-02-14T00:00:00Z The competitive exclusion principle states that two species cannot occupy the same niche in a habitat. Biology for AP Courses 2022-06-09T00:00:00Z The competitive exclusion principle states that two species cannot occupy the same niche in a habitat: in other words, different species cannot coexist in a community if they are competing for all the same resources. Concepts of Biology 2013-04-25T00:00:00Z Understanding the origin of Pauli’s exclusion principle would unlock explanations for all of these deep facts of quotidian life. Quantum Particles Aren’t Spinning. So Where Does Their Spin Come From? 2022-11-22T05:00:00Z Counting the number of possible combinations of quantum numbers allowed by the exclusion principle, we can determine how many electrons it takes to fill each subshell and shell. College Physics for AP Courses 2015-08-12T00:00:00Z The competitive exclusion principle states that no two species can occupy exactly the same niche in exactly the same habitat at exactly the same time. Miller & Levine Biology 2018-01-01T00:00:00Z Explain how two different species can coexist in the same habitat according to the competitive exclusion principle. Biology for AP Courses 2022-06-09T00:00:00Z The competitive exclusion principle states that two species cannot occupy the exact same niche in a habitat. Environmental Biology 2018-09-06T00:00:00Z Pauli’s exclusion principle was merely a special case of this spin-statistics theorem, as it came to be known. Quantum Particles Aren’t Spinning. So Where Does Their Spin Come From? 2022-11-22T05:00:00Z We shall see in this section that the exclusion principle is key to the underlying explanations, and that it applies far beyond the realm of atomic physics. College Physics for AP Courses 2015-08-12T00:00:00Z Because of the competitive exclusion principle, species inhabiting the same niche within the same habitat can find success by dividing resources. Miller & Levine Biology 2018-01-01T00:00:00Z Explain what would happen if the competitive exclusion principle were violated. Biology for AP Courses 2022-06-09T00:00:00Z The competitive exclusion principle works because if there is competition between two species for the same resources, then natural selection will favor traits that lessen reliance on the shared resource, thus reducing competition. Environmental Biology 2018-09-06T00:00:00Z To avoid some inconsistencies associated with the exclusion principle, it already had been suggested that quarks might come in three “colors.” Remembering Murray Gell-Mann 2019-06-06T04:00:00Z This statement is known as the Pauli exclusion principle, because it excludes electrons from being in the same state. College Physics for AP Courses 2015-08-12T00:00:00Z Figure 30.59 The Pauli exclusion principle explains why some configurations of electrons are allowed while others are not. College Physics for AP Courses 2015-08-12T00:00:00Z Explain how the competitive exclusion principle relates to this example. Biology for AP Courses 2022-06-09T00:00:00Z The Pauli exclusion principle determines the maximum number of electrons allowed in each shell and subshell.
