But the electrochemical results show that complexes exhibitcompletely irreversible redox behaviour which is different from thatfound in diiron proteins. 1.3 To obtain the diiron species which are stable to elec-trochemical reduction, a series of new tetranuclear cage ironspecies containing two 〓 cores, with using hexadentatepolybenzimidazole ligands, were synthesized and characterized by vari-ous spectroscopic methods. Their physical properties have been investi-gated. The crystal structures of 〓〓tetrakis (benzimidazol-2-ylmethyl)-1, 4-diaminobutane and 〓,〓-tetrakis ( N-ethylbenzimidazol-2-ylmethyl )-1, 4-diaminobutane were determined. They contain two 〓 cores which arelinked to each other by -〓-chain in the ligands.

1.3为了获得电化学还原稳定双核氧桥联Fe化合物，使用六齿配体合成了一系列含有两个〓单元四核笼状化合物，并用各种谱学手段表征了它们，还研究了它们的物理化学性质确定了〓L=N，N，N'，N'-四(苯骈咪唑基-1，4-丁二胺和〓，〓四-1，4-丁二胺化合物的晶体结构，它们含有两个〓单元，其中两个〓单元是通过配体的〓链桥联成四核笼状结构。

We got a conclusion that only biflavonoids bearing flavan moiety existed in Daphne gemus, that biflavanones and chamaechromonoids existed in Stellera genus, and that biflavanones and biflavonoids bearing flavan moiety existed Wikstroemia species. The opinion that biflavanones only existed in Stellera genus was corrected and they were also found in Wikstroemia genus.

通过总结发现，在瑞香属的植物中仅存在含有黄烷单元的双黄酮类化合物；狼毒属植物中存在双二氢黄酮类，狼毒色原酮类以及少数含有黄烷单元的双黄酮，而且目前发现狼毒色原酮类仅存在于该属植物中；荛花属植物中存在含有黄烷单元的双黄酮类和双二氢黄酮类。

Aimed at the complexity of fluvial strata, such measures as well cyclical comparison, step control and geological analysis of reference beds have been applied. Moreover the paper has developed a set of methods the techniques to extract the parameters controlling the formation of intra-sandbody thin interbeds. The present study has examined how thin interbeds affect the frame property and heterogeneity of individual sandbodies; revealed the permeability space distribution mode of meandering distributary channel's single side lithosomic body and straight distributary channel's aggrading lithosomic body. Through applying the distributary channel sandbody structural unit classifying and identifying method achievement, some horizontal wells have been deployed to dig the residual oil in the top of hick pay zone in the xing8-9 area, which shows better effect after they have been put into production.

针对分流河流砂体沉积特点采用了旋回对比、分级控制、不同相带区别对待的单油层对比方法；利用取心井、对子井等资料研究形成了分流河道砂体内部结构单元的倾角、倾向、规模等参数的提取方法；搞清了内部结构单元对单一砂体内非均质性的控制作用，建立了分流平原相单一点坝侧积体及顺直型分流河道单一加积体层内渗透率分布模式及剩余油分布模式，应用分流河道砂体结构单元划分方法识别研究成果，在杏树岗油田杏八九区纯油区部署了水平井，投产后见到了较好的厚油层顶部剩余油挖潜效果。

The story of the quantum revolution has been told so many times that it has become as ritualized as the stations of the cross. How Max Planck, faced with some curious observations about hot glowing objects, reluctantly proposed that light is sputtered out in packets — the quanta. How Albert Einstein , seeing deeper, realized that light must also travel that way, that its waves were also particles. How Bohr brought the graininess into the atom, with electrons hopping between orbits in quantum jumps. How Heisenberg, marooning himself on the bleak isle of Helgoland, saw that there were no orbits, that what happened inside atoms was different from anything that could be pictured by a human brain.

量子革命的故事已讲述过很多遍，就象讲述耶稣受难经过的画像一样已经仪式化，诸如：马克斯·普朗克面对炽热物体一些不寻常的观测数据，如何艰难地提出辐射是一单元一单元地射出的，这种最小的单元即能量子；爱因斯坦观察得更深刻一些，如何意识到光线也是这样运行的，光波也是粒子；玻尔如何利用量子跃迁过程中电子在轨道之间来回跳跃，来揭示原子的多微粒结构；海森堡自我流放到阴冷的赫尔戈兰岛上，如何观察到原子内部并没有轨道，其内部所发生的情况不同于人脑可想象出的任何情况。

The first column is made up of units referring to overvaluing of the blood relations（Oedipus marries his mother, Jocasta, for example）; column two expresses the undervaluing of such relations（Oedipus kills his father, Laius）; column three referring to the salying of the monster; and the forth column comprises names referring to some general order of human disability（'Oedipus'translates as 'swollen foot'）or, more specially, to 'difficulties in walking straight or standing up-right'.

第一组由高估血缘关系的神话素单元组成，比如：伊狄普斯娶了母亲卓卡斯塔；第二组由低估血缘关系的神话素单元组成，比如：伊狄普斯杀了父亲莱厄斯；第三组由征服怪兽的神话素单元组成，比如：伊狄普斯杀了怪兽斯菲克斯；第四组由一些代表人类普遍存在弱点或残废的名字组成，比如：&伊狄普斯&意思为&肿胀的脚&，也即表示此人不能向前直行或直立行走。
