CMOS（互补金属氧化物半导体）是构建集成电路的主流技术。它使用互补的p型和n型MOSFET对来构建逻辑门。其主要优势是静态功耗极低，因为在稳定状态下，互补对中的一个晶体管始终处于关闭状态，因此除了开关转换期间外，电流流动极小。

The discovery that europium-doped yttrium vanadate ([latex]YVO_4:Eu^{3+}[/latex]) could act as a brilliant red phosphor was a critical breakthrough for color television. Before this, red phosphors were weak, resulting in dull colors. The intense, narrow-band red emission from the [latex]Eu^{3+}[/latex] ion allowed for bright, vibrant color displays, dramatically improving the quality of color TV and setting the standard for display technology.

UNISURF 由法国工程师皮埃尔·贝塞尔 (Pierre Bézier) 于 20 世纪 60 年代为雷诺 (Renault) 开发，是首批真正的 3D CAD/CAM 系统之一。其核心创新在于使用了如今被称为贝塞尔曲线和曲面的技术。这些曲线和曲面是由一组控制点定义的参数曲线，能够直观地以数学方式创建复杂的车身自由形状。

Superconducting Magnetic Energy Storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil. The energy can be stored indefinitely as long as the coil is kept at superconducting temperatures, as there is virtually no energy loss due to electrical resistance. The stored energy is given by [latex]E = \frac{1}{2} L I^2[/latex].

The Ganz-Griesser whiteness index is a linear formula widely used, particularly in the textile industry. It is derived from CIE tristimulus values and is defined as [latex]W_{GG} = Y - Px - Qy + C[/latex], where P, Q, and C are constants specific to the illuminant and observer. For the D65/10° condition, the formula is [latex]W_{GG} = Y - 1868.322x - 3695.690y + 1809.441[/latex].

Lithium-ion batteries function via an intercalation mechanism, a reversible insertion of ions into a layered host material. During discharge, lithium ions ([latex]Li^+[/latex]) de-intercalate from a negative electrode (anode), typically graphite, and move through a non-aqueous electrolyte to intercalate into a positive electrode (cathode), typically a metal oxide. Electrons travel through the external circuit, creating current.

Q开关是一种产生高强度、短脉冲激光的技术。其工作原理是暂时抑制激光活动，使增益介质通过粒子数反转储存大量能量。然后，激光器的品质因子（Q值）迅速切换到高值，从而将储存的能量以单个强大的纳秒脉冲的形式释放出来。

CIE D系列光源是一套标准光谱功率分布（SPD），代表自然日光的不同阶段。最常用的是D65，其相关色温约为6504 K，代表平均正午日光。D50（5003 K）是另一个关键标准，常用于图形艺术。这些标准能够确保色彩还原的一致性。

Mode-locking is a technique for producing extremely short laser pulses, on the order of picoseconds ([latex]10^{-12}[/latex] s) to femtoseconds ([latex]10^{-15}[/latex] s). It works by forcing the many longitudinal modes of the laser cavity to oscillate with a fixed phase relationship. This causes the modes to interfere constructively, creating a single, intense, ultrashort pulse circulating in the cavity.

自上而下的合成是指从较大的块体材料开始，将其分解或图案化至纳米尺度，从而创建纳米材料。关键技术包括球磨等机械方法和光刻方法，例如光刻、电子束光刻和纳米压印光刻。这些方法通常用于创建结构化表面和集成电路，但可能会受到表面缺陷的影响。

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational kinetic energy. The energy stored is proportional to the square of the rotational speed. When energy is extracted, the flywheel's rotation slows down. The formula for stored energy is [latex]E = \frac{1}{2} I \omega^2[/latex], where I is the moment of inertia and ω is the angular velocity.

分子电子学探索利用单个分子或纳米级分子集合作为基本电子元件。该方法旨在构建微型化极限的电路，远远超越传统的硅基技术。关键元件包括分子线、开关和整流器，它们利用电子隧穿分子轨道等量子力学特性来实现功能。

失效物理学（PoF）是一种可靠性工程方法，它利用材料科学和物理学的知识来理解和模拟失效的根本原因机制。它并非仅仅依赖于以往失效的统计数据，而是通过分析导致性能退化和失效的物理过程（例如疲劳、腐蚀、蠕变）来预测失效。

The Quantum Size Effect describes the phenomenon where the electronic and optical properties of a material change as its size approaches the nanoscale. When the dimensions of a material become comparable to the electron's de Broglie wavelength, quantum confinement occurs. This quantizes the electron energy levels, leading to a size-dependent band gap, [latex]E_g(R) \approx E_{g,\b\u\lk} + \frac{\hbar^2\pi^2}{2R^2}(\frac{1}{m_e^*} + \frac{1}{m_h^*})[/latex].
