Here we see the two side-by-side.
我们现在看到它们两个并排放置。
On the left is the 'aa' as in 'bat' pure vowel sound being spoken on its own.
左边的“aa”是独立发音，“bat”中纯元音“aa”。
On the right is the word pan being spoken.
右边是正在读的“pan”字。
So you can see again that the corners of the mouth do not come back and up as much in the word pan as they do in the pure vowel sound,
所以，你可以再次看到，嘴角在pan这个词中不会像在纯元音中那样来回上扬，
and the jaw does not drop quite as much.
下巴也不会下垂的很多。
However, as you can see, the tongue position is the same.
但是，正如你所看到的，舌头的位置一样。
The other thing to note is that it is not a single sound, it is more of a diphthong sound
另一件要注意的是，它不是一个单一的音，更多的是一个双元音
– pan – of this modified aa going into a schwa before the N sound.
—pan—这个调整后的aa成为N音之前的schwa。
Paa-uh-nn, paauhn, pan.
Paa-uh-nn、paauhn、pan。
A few other words that have this 'aa' as in 'bat' followed by the nn consonant sound: animal, tan, and, pan.
其他几个有“bat” 中“aa”音，后跟nn辅音的单词，如：animal、tan和pan。
This modified aa vowel is the same when it is followed by the M consonant sound within the same syllable.
这个经过调整的aa元音在同一音节中后跟M辅音时相同。
For example, the word Pam. This is the same sound as in case 1 when the 'aa' as in 'bat' was followed by an N.
例如，Pam这个词。这与实例1里“bat”中的“aa”后面跟着N时的发音相同。
It is this modified 'aa' sound followed by a schwa.
这是经过调整的“aa”音，后面跟一个schwa音。
Pam.
Pam。
Other example words: dam, am, ambiguous.
其他示例词：dam、am、ambiguous。
The third case: when it is followed by an NG ng sound.
第三种情况：紧接着是一个NG音。
Now in IPA, when these are in the same syllable, again, the 'aa' vowel sound is written followed directly by the ng consonant sound.
在IPA中，它们在同一个音节中时，同样地，“aa”元音后面紧跟着ng辅音。
It is not, however, a pure aa sound. In this case,
然而，这不是一个纯aa音。
however, the sound is not the same as it is in the previous two cases where it was the modified aa followed by a schwa.
然而，在这种情况下，发音与前两种情况下不同，前两种情况下的发音是经过调整的aa，后接schwa音。
In this case, when it is followed by the NG sound, it is actually like the 'ay' as in 'say' diphthong.
在这种情况下，当它后跟NG音时，它实际上就像say双元音中的“ay”。
Let's take, for example, the word 'anger' and the word 'danger'.
举个例子，“anger”和“danger”两个词。
