The TPU one is synthetic

.The TPU one is synthetic
  TPU can be divided into a footwork and gathered the law in advance while formating the method, because response conditions are different, greater difference appears in the performance of the polymer. Among them the best method is that a footwork uses one pair of spiral shells' pole pushing out of machine to produce TPU. TPU had to a step legal system, it is one kind that inlays a section of line type polymer basically, the basic response type is:
 2nOCN-R-NCO+nHO-R'-OH+nHO-R" -OH CONH-R-NHCOO-R'-O-CONH-R-NHCOO-R" -On

太陽光能發電元件──太陽能電池

人們早在春秋戰國時代以前,就已經發現如何利用太陽能。在史書中也曾經記載「司垣氏掌水夫燧,取火於日」和「陽燧見日,則燃而為火」。根據考證,在這當中的「夫燧」和「陽燧」,就是類似凹面鏡的聚光集熱裝置。

What is meant by the fuel cell
The fuel cell is that one kind changes into a device of the electric energy chemical energy into directly, do not need to charge, so long as supplement the fuel and oxidant in succession, can operate and generate electricity in succession. The fuel and oxidant can't be mixed, but enter in the fuel cell separately, produce and react specifically in the positive pole of the battery and negative pole.
