    Bad at listening comprehension,so ask for professor HOU,Fortunately and certainly,she does very great.soon after the day ,she return me a completely  dictation frame on which help me deeper Understood the original text..


    here i corrected some professional verbs and nouns,may someday and someone have a little look,maybe i will get the more perfect translation,you know ,there is latter part of a piece of listening section.




    ...kind of front cup, which has perfect characteristics. The weight is only 1.4 kilograms and the speed rated  to 160 rpm at 36 volts. First, I trans flinches and add a lace to reduce di -misure. Then I build up adapter forest under the  real wheel sprocket.


    The issue is to avoid long chain especially for recombine some tracks. You can also call it a human power electric hybrid. Of course the efficiency is not as high as with a chain but there are some other advantages . For instance, the frame can be simpler and you can also recharge the batteries by the bike stationery or on the stop. 


    The generator under the bottom bracket are climbed by special aluminum profile. The sprocket has to be lined with a chain rein. the di-sensor of the generator set so that there is enough clearance  for the chain and the crank. The power output the generator is a three phase alternating current. By using a three phase bridge rectifier  to get a  DC output. 


    First I’ve leisured DC Out-Put voltage I can get more than 70 volts without load. Enough charge of ....battery.. is 44 volts. 

    Now I’ve connected the battery to the rectifier .I have to  pedaled fast enough to exceed the 50 volts ...battery ..that .... .......

    Here are some details of the use of my Trike (tricycle)which I built from scratch...
