This happens in a so called reaction center inPhotosystemⅡ, where a tetrameric chlorophylls (P680) absorb the solar light andinitiate photoinduced electron transfer reaction to the acceptors, quinone A and B. Thephoto-oxidized P680 retrieves the electron from a Mn4Ca cluster via a tyrosine, thelatter components are also called oxygen evolving center. After 4 photo-processes, twomolecular water are oxidized to a molecular oxygen.

在光系统二的活性中心，叶绿素P_(680吸收太阳光，将电子传递给电子受体、醌A和醌B，同时光氧化的P_(680)~+从释氧中心中得回电子(通过Tyr_z氧化Mn4Ca簇)，经过四次光诱导电子转移，两分子水最终被氧化生成一分子氧气。

Is a tetranuclear lanthanum complex.

化合物 16 是一个四核镧簇。

Part 6 explores the reaction system containing O-phthalate, Mn〓 and α,α'-diimine, and yields six novel complexes 16～20 possessing binuclear and tetranuclear matello-crown aether as well as 1-D linear structures, indicating that O-phthalate is a potentially useful ligand to give manganese species in a discrete form.

研究了邻苯二甲酸/锰/双齿亚胺（2，2'-联吡啶和1，10-邻二氮杂菲）的反应体系，合成出6个新颖的双核、四金属冠醚和一维线性结构的化合物16至20，表明邻苯二甲酸是合成有限核数锰簇的有用配体。

The paint makes me feel encouraging because it is newly painted on, just like celebrating spring festival in a new room, you feel quiet, clean, and thriftily.

油漆的气味，因为簇崭新，所以是积极奋发的，仿佛在新房子里过新年，清冷，干净，兴旺。

Seventh place: Shirley Owens from Michigan State University captured the hair-like trichomes on Thunbergia alata (Black-eyed Susan vine) with 450X zoom.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
