The main results are as follows.1. The UV-visible absorption spectra, the spin-trapping EPR measurements, and the DPA (9,10-diphenylanthracene) bleaching experiments showed that (1) HB-Net exhibits much improved light harvesting efficiency in the phototherapeutic window (600-900 nm) as the result of its remarkable absorption red shift with respect to HB;(2) HB-Net remains the generation abilities of semiquinone anion radical, superoxide anion radical, hydroxyl radical, and singlet oxygen, but with much lower efficiencies than that of HB, most likely due to its very short triplet excited state lifetime.

E. OCB mode LCD elements . Then,we added bi-functional powder and LC E7 in the bulk copolymer of Poly Acrylic Acid and EOPO,then poured the LC solution,and exposed it with 5V voltages under ultraviolet radiation. Finally,we observed the changing phenomena of the planar display of OCB cell with additional external voltage under polarized microscopy . It can be observe obviously the polymer wall in OCB cell when NO.4 LC solution having concentration of 3％ wt . At the same time,the polymer which didn't sheltered by mask will polymerize,then,lead LC into high inclined angle alignment. And it formed discontinuous structure along mask affected LC which surrounded the wall. The results measured by photoelectric instruments showed the discontinuous structure not only keeps the inner LC structure at twist mode,but also promotes the originated respond-velocity of OCB.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
