使用说明与常见问题How-to & FAQ
「LC 谐振频率」是什么？What is the LC Resonant Frequency tool?
f₀ = 1 / (2π √(L C))。本地处理。可设置「电感 H」、「电容 F」。f₀ = 1 / (2π √(L C)). Processed locally. Settings: Inductance H, Capacitance F.
如何使用「LC 谐振频率」？How do I use the LC Resonant Frequency tool?
在「LC 谐振频率」中，填写「电感 H」、「电容 F」等参数，结果会随输入实时计算并显示在下方。In the LC Resonant Frequency: Fill in "Inductance H", "Capacitance F"; results are recalculated instantly as you type.
串联和并联 LC 有区别吗？Is there a difference between series and parallel LC?
对理想的 L 和 C，串联和并联谐振频率相同：f₀ = 1 ÷ (2π√(LC))。区别在于串联谐振时阻抗最小、并联谐振时阻抗最大；有电阻损耗时并联谐振频率会略有偏移。For an ideal L and C, series and parallel resonance share f₀ = 1 ÷ (2π√(LC)). The difference is that series resonance has minimum impedance and parallel has maximum; with resistive losses the parallel frequency shifts slightly.
能举个计算实例吗？Can you show a worked example?
例如在「LC 谐振频率」中填 电感 H = 1e-3，电容 F = 1e-6，结果区显示：谐振频率 Hz：5,032.9212；kHz：5.0329For example, entering Inductance H = 1e-3, Capacitance F = 1e-6 in the LC Resonant Frequency gives: Resonant Hz: 5,032.9212; kHz: 5.0329
哪些输入会被检查？Which inputs are validated?
「LC 谐振频率」会检查这些输入——「电感 H」、「电容 F」：必须填写，须大于 0；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The LC Resonant Frequency checks its inputs — "Inductance H", "Capacitance F": required, must be greater than 0; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.
有哪些选项可以调整？What options can I adjust?
「LC 谐振频率」的设置：「电感 H」默认 1e-3；「电容 F」默认 1e-6。每次生成结果都按当前设置处理。Settings in the LC Resonant Frequency — "Inductance H" default 1e-3; "Capacitance F" default 1e-6. The result always uses the current settings.
计算结果可以用于作业或工程吗？Can I use the results for homework or engineering?
「LC 谐振频率」使用教科书标准公式（公式写在说明和常见问题中），适合学习和估算核对；涉及安全的工程设计请以规范和实测为准。The LC Resonant Frequency uses standard textbook formulas (given in the description and FAQ), which is good for learning and checking estimates; for safety-critical engineering follow codes and measured values.
