Normally a headphone amplifiers has a very low output impedance which gives the amp tight control over the headphone action. 翻一下:一般情况下耳机放大器为了对耳机控制有很低的输出阻抗。
Disulfide-stabilized Fv antibody ( disulfide stabilized Fv fragments, dsFv ) is more stable than single-chain antibody, but the antibodies also have very low output and high efficiency recovery of the defects. 二硫键稳定Fv抗体(disulfidestabilizedFvfragments,dsFv)比单链抗体更加稳定,但是该种抗体也具有产量很低且复性效率不高的缺陷。
The phenomena of high salinity content, violent salt return, soil salinity changed frequently in vertical direction, which made the soil have very low output and agricultural benefit. 盐碱地普遍存在盐碱重,返盐强烈,盐分垂直变化明显等问题,造成土壤产出率低且不稳,农业经济效益不高。
But the nonlinearity of RF power amplifier induced distortion of digital multi-level modulated signal which have high peak-to-average power ratio. Amplifier can only work on very low operating point, with lower output power and efficiency. 但是射频功率放大器的非线性特性使得峰均比很高的数字多阶调制信号产生了很大的失真,放大器只能工作在很低的工作点,输出功率和效率都非常低。
To reduce torque ripple and achieve higher performance in very low speed range, indirect torque control method is realized in a dual-DSP control platform and improved by considering the influence of the stator resistance variation on the voltage vector output. 为了减少异步电机低速时转矩脉动并达到较高的性能,一种考虑了定子电阻变化对输出电压影响的改进间接转矩控制方法在双DSP平台上实现了。
