电化学势和热力学平衡

雷诺平均纳维-斯托克斯 (RANS) 方程是湍流的时间平均运动方程。这种方法称为雷诺分解，将流动变量分解为平均分量和波动分量。平均过程引入了一个附加项，即雷诺应力张量，它表示湍流的影响，必须对其进行建模才能实现闭合，从而使模拟在计算上易于处理。

The Curie temperature ([latex]T_c[/latex]), or Curie point, is the critical temperature above which certain materials lose their permanent magnetic properties. For ferromagnetic materials, they become paramagnetic above [latex]T_c[/latex]. This transition is a phase transition where thermal energy becomes strong enough to overcome the quantum mechanical exchange interactions that cause spontaneous magnetic ordering of atomic moments.

塞曼效应是指在施加外部静磁场时，原子谱线分裂成多个分量的现象。这种分裂的发生是因为磁场与原子轨道和自旋角动量相关的磁偶极矩相互作用，从而改变了电子的能级，这一现象对于探测原子结构至关重要。

铝热剂具有极高的活化能，使其在室温下稳定且难以点燃。点火需要达到约 1,300 °C (2,400 °F) 的温度。这通常不是通过直接火焰来实现的，而是借助中间高温引发剂（例如燃烧的镁带或专门设计的烟火引信）来实现的，这些引发剂可提供引发反应所需的局部能量。

The distribution ratio (D) is a key equilibrium parameter in Liquid-Liquid Extraction (LLE), defined as the total analytical concentration of a solute in the organic phase divided by its total concentration in the aqueous phase. [latex]D = \frac{[S]_{org,total}}{[S]_{aq,total}}[/latex]. Unlike the partition coefficient (K_D), D accounts for all species of the solute, including dissociated or complexed forms, making it pH-dependent.

汉普森-林德循环利用焦耳-汤姆逊效应和再生冷却技术，将空气等气体液化。高压气体在逆流式热交换器中被从膨胀阀返回的低温低压气体冷却。这逐渐降低阀门处的温度，直至降至临界点以下，开始液化，这构成了现代气体液化工业的基础。

The Lorentz force law describes the total force experienced by a point charge moving through a combined electric and magnetic field. It is the sum of the electrostatic force and the magnetic force. The governing vector equation is [latex]\mathbf{F} = q(\mathbf{E} + \mathbf{v} \times \mathbf{B})[/latex], where [latex]q[/latex] is the charge, [latex]\mathbf{v}[/latex] is its velocity, [latex]\mathbf{E}[/latex] is the electric field, and [latex]\mathbf{B}[/latex] is the magnetic field.

镍镉电池由瓦尔德马尔·荣格纳（Waldemar Jungner）于1899年发明，以氢氧化镍（NiO(OH)）为正极，以金属镉（Cd）为负极，并使用氢氧化钾（KOH）等碱性电解质。镍镉电池以其较长的循环寿命和良好的低温性能而闻名，但也存在记忆效应和镉的毒性问题。

The absolute electrochemical potential of a single electrode cannot be measured. Instead, potentials are measured relative to a universally accepted reference. The Standard Hydrogen Electrode (SHE) is the primary reference, assigned a potential of exactly 0 volts under standard conditions (1 M [latex]H^+[/latex] concentration, 1 bar [latex]H_2[/latex] gas, 298 K). All other standard electrode potentials are reported relative to this zero point.

升华是一种用于纯化化合物（尤其是挥发性固体）的实验室技术。将不纯的固体缓慢加热（通常在减压条件下），使其直接升华为气体。然后，该气体以纯固体的形式沉积在冷却的表面上（称为冷指），而非挥发性杂质则留在原始容器中。

色温是可见光的一种特性，用于测量其色调，范围从暖色（淡黄色）到冷色（淡蓝色）。色温定义为理想黑体辐射体（其辐射光的色调与光源的色调相似）的温度。其测量单位为开尔文 (K)。
