Monostable: one pulse of 1.1 × R × C after each trigger. Capacitor tolerance, often 10–20%, changes the timing by the same amount.":"无稳态：f = 1.44 ÷ ((R1 + 2·R2) × C)；输出处于高电平的时间为0.693 × (R1 + R2) × C，处于低电平的时间为0.693 × R2 × C，因此占空比始终高于50%；要将占空比降至50%以下，可在R2两端并联一个二极管。单稳态：每次触发后产生一个时长为1.1 × R × C的脉冲。电容容差通常为10–20%，会使定时发生相同比例的变化。","AWG sizes come from a formula: each step of 6 gauges halves the diameter, and 36 AWG is 0.127 mm. A smaller number is a thicker wire. How much current a wire may carry depends on its insulation, how it is installed, and the local electrical code, so look that up in the code that applies where you are rather than relying on a single table; when in doubt, choose the thicker wire.":"AWG线规源自一个公式：线规每增加6级，直径就减半；36 AWG为0.127 mm。数字越小，导线越粗。导线的载流量取决于绝缘层、安装方式和当地电气规范，因此请查阅适用于所在地区的规范，不要只依赖单一表格；如有疑问，请选择更粗的导线。","AWG to mm²":"AWG换算为mm²","C (µF)":"C（µF）","Convert":"换算","Copper resistance":"铜电阻","Copper thickness":"铜厚度","Copper weight (oz/ft²)":"铜重量（oz/ft²）","Cross-section":"截面积","Cross-section (mm²)":"截面积（mm²）","Current (A)":"电流（A）","dBm ↔ watts":"dBm↔瓦特","dBu ↔ volts":"dBu↔伏特","dBV ↔ volts":"dBV↔伏特","dBW ↔ watts":"dBW↔瓦特","Decibel calculator":"分贝计算器","Diameter":"直径","Direction":"方向","Duty cycle":"占空比","Enter a cross-section in square millimetres.":"输入以平方毫米为单位的截面积。","Enter a number.":"输入一个数字。","Enter a value above zero.":"输入大于零的值。","Enter R and C.":"输入R和C。","Enter R1, R2, and C.":"输入R1、R2和C。","Enter the current, temperature rise, and copper weight.":"输入电流、温升和铜重量。","Frequency":"频率","From decibels":"从分贝转换","Gauge (AWG)":"线规（AWG）","High time":"高电平时间","Inner layer":"内层","Layer":"层","Low time {0}":"低电平时间{0}","Minimum trace width":"最小走线宽度","mm² to AWG":"mm²换算为AWG","Mode":"模式","Monostable (one pulse)":"单稳态（单个脉冲）","Nearest AWG":"最接近的AWG","Outer layer":"外层","PCB trace width calculator":"PCB走线宽度计算器","Period":"周期","Power ratio (dB)":"功率比（dB）","Power ratios use 10 × log10, so doubling the power is +3 dB; voltage ratios use 20 × log10, because power goes with the square of voltage, so doubling the voltage is +6 dB. dBm is power against 1 milliwatt (30 dBm = 1 W), dBW against 1 watt, dBV voltage against 1 volt, and dBu against 0.775 volts, the voltage that puts 1 mW into 600 Ω.":"功率比使用10 × log10，因此功率加倍为+3 dB；电压比使用20 × log10，因为功率与电压的平方成正比，所以电压加倍为+6 dB。dBm以1毫瓦为基准功率（30 dBm = 1 W），dBW以1瓦为基准功率，dBV以1伏为基准电压，dBu以0.775伏为基准电压，即在600 Ω电阻上产生1 mW功率的电压。","Pulse length":"脉冲长度","R (kΩ)":"R（kΩ）","R1 (kΩ)":"R1（kΩ）","R2 (kΩ)":"R2（kΩ）","Ratio":"比值","Smallest AWG at least as large":"不小于该值的最小AWG","The IPC-2221 formula: current = k × ΔT^0.44 × area^0.725, with the area in square mils and k = 0.048 for outer layers, 0.024 for inner layers, which shed heat less well.
