Based on the plane- wave pseudo- potential and generalized gradient approximation，the structure，electric property and optical property of poly- para -phenylene vinylene（PPV）were studied.Analyzed the relationship between the distribution and structure of electronic states. Gave out the density of states and the band structure of system before and after doping of PPV. Under the standard conditions，the atom in PPV cell are in the same plane，the structure constants such as bond lengths and bond angles are consistent between experiment and theory. Replaced the C atom with N atom in PPV，formed poly ppyridyl vinyline（PPyV），after calculating，found out the energy band has slight difference with PPV materials，and the wave form of absorption spectrum are nearly the same，however，obvious blue shift occurs in absorption peak. The results comply with the existing literature.

Because of the asynchronous characteristic of I/O，Node.js is quite suitable for developing server-side JavaScript applications. To implement concurrent asynchronous I/O control，developers have to write tedious code manually，it becomes a barrier to developers. Based on the concurrent counter，a concurrent flow- control framework can be constructed. The framework achieved concurrent control between multiple asynchronous I/O in a direct viewing way. Thus，it benefits server- side JavaScript developments and also promotes the efficiency of development.
