分享一些电子工程相关英语句子。

1.Placed in parallel with a voltage source, they limit current to a device. In series with a voltage source they make up a voltage divider. 1.电阻与电源并联连接,则电阻限定流入装置的电流.电阻与电源串联,则电阻便成为电压分压器. 2.The fifth band, when present, indicates the failure rate (in percentage) per 1000 hours of service. This is sometimes called the reliability factors. 2.第五条色带,当其出现,表示每使用1000小时的故障率(用百分比表示).它有时也被称为可靠性因子。 3.Why is skew important? In high-speed systems, clock skew forms an important component of timing margin. A skew of 1 ns is a significant portion of a 15-ns cycle time. If the timing budget does not allow for skew, it is highly likely that the system will perform unreliably. 3.为什么偏移这么重要？在高速系统中，时钟偏移是时序富裕量的重要组成部分。在一个以15纳秒为周期的时间里，1纳秒的偏移都是很显著的部分。如果时序预算不允许偏移，系统很可能无法稳定运行。 4.In today's designs, with clock rates over 100 MHz and rise times commonly 1 nanosecond (ns) or less, designers cannot ignore the role interconnections play in a logic design. 4.在当今的设计中，时钟速率都超过了100MHz，并且上升沿通常只有1纳秒或者更少，设计者不能忽视在逻辑设计中互连的重要性。 5.The faster clock rates and rise times increase both capacitive and inductive coupling effects, which makes cross talk problems greater. They also mean shorter time for reflections to decay before the data is clocked and read, which decreases the maximum line length that can be used for unterminated systems. 5.更快的时钟速率和上升沿都将增加电容耦合及电感耦合效应，这使得串扰问题更加严重。这也意味着在数据被写入和读取之前的反射衰减时间更短，它减少了无终端系统中最大的可用线路长度。更多精彩内容，请继续关注本网站。
