峰平谷三个时段的电费,度数各不同,三种单价,如何求平均单价

As a member of the company,I have gone on business trips to Shenyang,Beijing and Shanxi.I have been to Pinggu and Yizhuan in Beijing.
"BOE" is the largest company I have worked for,the work assigned by which is of the most stress.But fortunatiely there are you.I can feel your cuteness and I am fond of kidding with you.Although we have returned to our company,we sometimes mention about you,especially a girl with white teeth and big eyes.
That's all.Best wishes for your job!

A Baocheng order to Shenlong heroes follow the kung fu master and the Furious Five with the protection of the Valley, living a quiet life

各地区在用电上因地域、产业、气候等条件不同,其尖、峰、平、谷的时间也不同.在夏季,尖都在上午工作和下午工作时间,因为此时既有工厂机器又有空调运转.峰值应该在中午、晚餐时段.早晨和睡觉前应该是平.用电谷时应该在人和机器都休息的时段.

是的,新闻已经公布了：当晚地震,是唐山余震,反复期十多年啊.
唐山距离平谷很近,要注意.

Valley of Peace
官网上这么说的.

Po the Panda was a waiter in a small noodle restaurant who was popularly known as the laziest animal in the Peace Valley.Although he dreamt about being a Kungfu Master everyday,his character had decided his fate:Po was an useless nobody.When strong enemies attacked,animals in the valley held a competition to choose a Kungfu Master who would lead everyone to fight.Out of the blue,Po accidentally intruded into the competition field and Master Ooguay chose this lazy panda as the saviour who would take on the responsibilities of saving the Peace Valley!Kungfu Masters in the valley were now worried,as it was really,extremely uneasy to train Po into an outstanding Kungfu Master.
自己翻译的哟,还好看过功夫熊猫所以比较容易.

A中在滑动变阻器滑片向左移动的过程中,电流表示数变大,灯泡分的电压增大,电源电压不变,则电压表示数减小.B中电路的总功率最大值为电流最大时,即小灯泡的额定电流0.5A,最大功率为p=18v*0.5A=9W.C中小灯泡的电功率最小值是电压表示数是15V时,灯泡电压3V,功率是0.75W,D中滑动变阻器允许调节的最小值是电流最大时,此时灯泡正常发光,电压时6V,电流是0.5A,滑变电压是12V,电阻是24欧姆,滑动变阻器允许调节的范围是24-60.所以C正确
