As well as用作并列连词，在科技英语中是很常见的。普遍流行的一种见解认为："as well as用作并列连词时，着重的不是as well as之后的词，而是它之前的词。所以 但是，笔者在如：It is to be noted that Thevenin 's theorem applies to AC as well as to DC circuits. 要注意，代文宁定理不仅适用于直流电路，也适用于交流电路。 在这句话中，作者所强调的是as well as前面的部分。上述定理和定律不但对直流电路而言是正确的，对交流电路而言也同样是正确的。 显然，这句话所强调的恰好是as well as 后面的部分。值得注意的是，强调后面部分的情况并非个别。下面这些句子都是从近年出版的英文原著中摘抄下来的： 1. The term IMPEDANCE is applicable only to AC circuits. Its unit of measurement is the ohm. It has a magnitude as well as phase angle. It is a complex quantity. "感抗"这个术语只适用于交流电路，其测量单位为欧姆。感抗不但有幅值，而且有相角，它是一个复数量。 2. Note that Ohm's law holds true for DC as well as for AC circuits. However, when analyzing AC circuit, it is important to consider the magnitude as well as the direction of phasor quantities. 要注意，欧姆定律不仅适用于直流电路，对交流电路也同样适用。不过，在分析交流电路时，重要的是不仅要考虑相量的幅值，还要考虑相量的方向。 3. The electrical power supplied by the source to the circuit is given by P=VI(watts). The equation is applicable to a circuit as well as to a component in a circuit. |
