A代表物质吸光度,透过率T=I/I0,其中I0表示入射前光的强度,I表示透过介质后的光强.这些相信楼主张大哥都已知道,你提问的重点是在于那个符号吧,这其实只是一个小的数学变换,我们定义介质的吸光度A=lg(I0/I)=-al(a为吸收系数),而T又为I/I0,经变换后A就等于-lgT.

C,稀释的时候,溶液的浓度降低,光的透过率增加,且由于物质没有变化,特征峰没变,就是最大吸收峰不移动.

lambertw是matlab的一个函数 意思是x*e^x=W;

其实你只要将这个结果再次放入Command 窗口 就可以运行处结果了

注意这句话:当“合适波长”的单色光通过某溶液并被吸收时.题中已告诉你波长已确定,即与波长有关的摩尔吸光系数就固定下来了,不再是变量.所以C是错的.其它不用解释.
所以选E.

Ben Lambert, the famous French singer, is talking a long vacation this summer!
本句为进行时态,其中 the famous French singer 是 Ben Lambert 的同位语,说明他的身份。短语 take a vacation 度假
He thought about going to Greece or Spain, but decided on Canada.
going to Greece or Spain 是动名词短语作介词 about的宾语,短语decide on 决定(先去加拿大)。

“I always take vacations in Europe,”he said. “This time I want to do something different. I heard that Canada is beautiful, and I know there are many people there who speak French.”

something different,different是something的后置定语。
I heard that Canada is beautiful, and I know there are many people there who speak French, heard 和 know 后都是宾语从句。
Ben is going to Canada’s Great Lakes. He is leaving the first week in June and staying until September.
be going 和 be leaving and staying 都表示即将要发生的事
He plans to have a very relaxing vacation.
plan to do sth. 也是表示打算的一种用法,
“I’m taking walks, going fishing, and going bike riding. I’m planning to spend time in the beautiful countryside.
上面的三个进行时态都表示计划好的将来。
I hope I can forget all my problems! At night,
I’m renting videos and sleeping a lot...

be renting and sleeping此处也是表示旅游期间的计划,是将来。
A great vacation! I can’t wait!”
I’ll be a new man when I return to paris
只有这个句子用 will 表示将来。
总结:本段中用了几种不同的方式表示将来:
1. be going 打算
2. 现在进行时表示正在着手进行的中的将来
3. will do 有可能性的将来
4. 一般现在时 plan to do 表示日程表排定的将来
