量子力学

In the quantum mechanical approach, injected electron with definite spin direction in nearly free electron gas is assumed.

量子力学方法中，我们假设具有明确方向自旋的电子被注入到自由电子气。

Also, in quantum mechanics, the use of the term particle refers to an elementary or subatomic particle.

同样在量子力学里，使用术语粒子指的是一基本或亚原子粒子。

But just changing the understanding about nature, we can know photon as the elementary particle of matter.

物质世界：按照爱因斯坦对光子的理解，以及量子力学对光子的研究，光子不可能是现代物质模型下的基本粒子，如果光子是物质的基本粒子，任何物体在相对静止的情况下都没有质量，物质没有静止质量的意义太可怕了，我们摸不到物体，看不见对方，不能利用任何物质，这是我们现实生活中不可能存在的物理模型。

Quantum entanglement is one of the most profound features of quantum mechanics.

量子纠缠是量子力学最显著的特征之一。

In 1928, he was appointed Professor of Theoretical Physics at ETH Zürich in Switzerland where he made significant scientific progress.

1924年为了解决观测到的分子光谱与正在发展的量子力学之间的矛盾泡利提出了一个新的自由度。

Secondly, based on the decomposition of gauge potential and the φ-mapping theory,φ-topological field theory of vector and spinor field is established and the Euler class is quantized by nodal indices of vector field.

作为它在量子力学中的应用，分别给出了自旋为零和自旋为1／2粒子的整数及半整数量子化条件，发现它们仅取决于物理系统的内部对称性。

By using the ansatz method, we get an exact quantum solution of the system.

通过试探解方法，得到系统的量子力学精确解。

Van Fraassen's interpretative theory of quantum measurement is not only the core of his philosophy of quantum mechanics,but also the theoretical foundation in his philosophy of science,constructive experimentalism.

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
