In the research of prescription, through the experiments we knew the influence from the Nb_2O_5 or Y_2O_3 single donor doped on high-temperature PTC ceramic, and got the curve graph drawing the resistivity and mixing quantity. In order to restrain lead volatilize and mix the rang of donors to neutralization the harmful acceptor impurity in raw materials, adopt the prescription design of Nb_2O_5 and Y_2O_3 double donors-doped. From the result, we know that regulation proportion of Nb , Y double donors, can make high-temperature PTC ceramics semiconducting, the pottery demonstrates good electric performance.

The influence of position of the substitution, strength and number of donors and acceptors, and their coplanarity and asymmetry is discussed. The results indicate that the molecules may have larger first hyperpolarizabilities when the molecules have stronger and more donors and acceptors, large asymmetry of HOMO and LUMO, better coplanarity and higher accentricity. This work attemps at finding out the relationship between the structure and the property, thus providing theoretical basis for designing nonlinear optical molecules.

The factors such as conjugate framework withsmall conjugation energy, central asymmetry, long conjugate chain,introduction of electron donors-acceptors, strong electron-donating orelectron-withdrawing abilities, long distance between electron donors andelectron acceptors, good coplanarity and so on lead to high third-order optical nonlinearities.

Donor sends out donation à Wait for schools which have been approved for construction à EEP assigns school to donor on a first-come-first-serve basis à EEP sends out school application and brief description of school condition to donor à Approved school begins construction – on average, six months is needed to finish construction. However, if circumstances are not ideal (e.g., inclement weather, bad road conditions and etc) or if the school is located in a very remote area (workers need to carry building materials up the mountain) then a longer time is necessary à Construction completed à Spring and Fall season, EEP volunteers inspect completed schools and take pictures for completion reports à Upon return to the US, prepare pictures and completion reports for donors (Approximately 2-3 months time)à Send out school completion reports to donors
