英语翻译
in fig .1-7c all voltages are marked in the -to+sense
in going clockwise around the loop.the voltmeters are
connected as shown in fig.1-7d to measure voltages u'1,u'2
and u'3.nothing that the voltmeter readings are the same
as the variable values,we find that fig.1-7 fundamental
property of voltages around a loop Thus the sum of voltages
taken in the -to+sense around the loop adds up to zero.having
eq.(1-3a),we could have obtained eq.(1-3b)by recognizing that
in fig.1-7e u1 and u2 are designated in the + to
-sense,whereas u'3is designated in the -to+sense in going
clockwise around the loop.as show in fig.1-7f,the voltmeers
are connected so that they measure the vaeible values(not
their negatives).the result is.
which indicates that,around the loop,the sum of voltages
taken in the +to-sense equals the voltage taken in the -to
+sense,or the sum of voltages in one sense minus those in
the other sense is zero.by recognizing that u'3=-u3,we see
that eq.(1-3c) reduces to eq .(1-3a).alternatively,by using
u1=-u'1and u2=-u'2,eq.(1-3c) can be made the same as eq.(1-3).

在图.1-7C所有电压被标记为+感
顺时针方向围绕loop.the电压表去
连接所示图7D来衡量的电压u'1,u'2
和u'3.没有电压表的读数
作为变量的值是相同的,我们发现,图1-7基本
属性围绕一个循环的电压,因此,
+环路周围的感电压的总和加起来到zero.having
当量(1-3a)的,我们已获得式(1-3b)中,通过认识到
,图1-7e的u1和u2被指定在+
检测,而u'3is的指定在+感在
顺时针方向绕图1408米的的loop.as显示,voltmeers
连接,使他们测量vaeible的值(不是
他们的底片),其结果是,
这表明,围绕循环,电压的总和
在+检测的电压等于
+感的总和,或在一种意义上的电压减去
其他意义上的zero.by认识是u'3 =-U3中,我们看到
,方程( 1-3c)的简化式(1-3a)的可替代地,通过使用
U1 =-u'1and U2 = u'2时,方程(1-3c)的可制成式相同(1-3. ).
