For the part of radiation with more than 500 eV energy of quanta, remarkable deviation from the Planckian-spectrum is observed.

It was found that the geometries of the studied materials were significantly affected by the ring size and intramolecular charge transfer. The HOMO level, LUMO level, and band gap of the studied model compounds were well controlled by the acceptor strength. However, the electronic properties of the studied polymer showed a significant different trend with the acceptor strength due to the geometrical transformation. The model compound of EDOT-TP and T-TP has the aromatic geometry but is transformed to the quinoid geometry for large intramolecular charge transfer. The small bond length alternation and large acceptor strength in the EDOT-BDP polymer also results in the smallest Eg of 0.7 eV among the studied polymers.

我们发现环的大小以及分子内电荷转移对结构有很大的影响，而小分子的HOMO、LUMO和能隙受到电子受体强度所控制，然而，高分子的电子特性与其构成分子却有明显不同的趋势，这主要是由於分子结构的转变，如小分子EDOT-TP以及T-TP因分子内电荷转移，使其高分子结构由aromatic转变成quinoid；而EDOT-BPP因其键长改变量小和良好的电子受体强度，使其能隙仅0.7个电子伏特。

At a fixed forward voltage, the current is an exponential function of reciprocal temperature,from which the effective barrier height was determined to be 0.784 eV and 0.531eV for the C70/n-GaAs and C70/p-GaAs contacts, respectively.

电学测量表明两种接触均是强整流结，在偏压为±1V时，它们的整流比分别大于106和104，以及在固定正向偏压下，它们的电流都是温度倒数的指数函数，从中确定了它们的有效势垒高度分别为0.784eV和0.531eV。

Validity of the model and its parameters were checked by experimental response curve at energy of 288 eV.

In contrast to the EV-1, the Roadster is supposed to go about 250 miles on a single charge.

目前，美国每加仑的汽油价格为3 美元，用电的成本要更低一些。

In 1901, he moved to New York City with his brother, composer John Rosamond Johnson, who put "Lift Ev'ry Voice and Sing" to music.

在1901年时，他和他的兄弟搬到纽约市，他的兄弟就是作曲家约翰罗沙蒙强森，也是把强森的歌曲「每个人都要开口大声唱」加入到音乐剧里的推手。
