For instance, at a very low level, in my case, I find it very easy to be friendly with people I talk with for a couple of minutes in the bus or in the street.
例如在很低的水准上就我个人而言，我觉得很容易与一些在公交或街上，聊了几分钟的人感到友好。
Using Schottky barrier diodes for D1 and D2 rather than common diodes reduces the low-level voltage on the bus, improving the noise margin.
使用肖特基二极管d1和D2，而不是普通二极管，为的是减少总线上低状态电压，改进噪声极限。
Almost all the power converters in use up to now are line-commutated, when the level of active power is low, and reactive power consumed is high, being very harmful for the connection bus voltage.
至今几乎所有的电力变换器为在线换向式的当有功功率较小，而消耗的无功较大时，对所联接母线的电压是非常有害的。
