一.引子说不清楚,为了何种原因,很小的时候,萨尔瓦就非常喜欢流浪这两个字。他总觉得流浪是一种洒脱和不拘,直到很久以后,萨尔瓦才明白,流浪是一种无奈和沉重。二.相识认识凯丽也许是萨尔瓦一生中最狼狈的时候,因为那时侯他正遭遇到十个骷髅兵的围攻,对于喜欢流浪的他来说,是没有击败它们的实力的。当他以为这个地下城将成为他生命终点的时候,凯丽正好出现了。那种声音是萨尔瓦一生所无法忘怀的,他从来没有想到过,一个娇柔的女孩能发出那样充满斗志,狂放的声音来,他总觉得这样的一个女孩是应该成为一个牧师的,而 相似文献

If H is a bialgebra, B is a left H-module algebra and a left H-comodule coalgebra, the smash product algebra structure and the smash coproduct coalgebra [1]structure over BH can form a bialgebra in certain conditions [2],called biproduct and denoted by BH.We present the formulas of quasitrangular structure of biproduct if it contains a quasitrangular structure.We obtain the necessary and sufficient conditions for such that it becomes a quasitriangular bialgebra. 相似文献

Based on some 40 billion cosmic ray events collected from 1997 to 2005 by the Tibet Air Shower Array experiment (a major scientific collaboration between China and Japan) operating at the YangBaJing Cosmic Ray Observatory (90.522 E, 30. 102 N; 4300 m above sea level) near Lhasa in Tibet, a two-dimensiondl cosmic-ray intensity map in the sky was obtained with very high directional granularity and unprecedented precision in intensity at a level of 10-4. 相似文献

Fig. The absorption 《科学通报(英文版)》2000,45(10):914-920
Histidine coordinated to Chi a is a distinct characteristic of Chl ain vivo. By using histidine analogue of 1-methylimidazole (C4H6N22) and measuring the UV/vis absorption, CD and MCD spectra of the interaction between C4H6N2 and Chl a in CCI4, we have obtained that: (i) In pure CCl4 solvent, Chl a molecule is in five-coordinate state, and two Chl a molecules form an asymmetric compact-dimer with strong
coupling interaction. We propose that the two Chl a molecules are connected by two unequally coordinated Mg-O bonds (the two
oxygen atoms come from the C=O of C131 keto and C17 ester, respectively); (ii) when the molar ratio of C4H6N2/Chl a is 0.5 or 1 (corresponding to 2Chl a · 1C4H6N2 and 2Chl a · 2C4H6N2, respectively), significant changes have been observed in the absorption, CD and MCD spectra, which indicate that the Chl
a remains in dimer form, but the coupling interaction between them reduces greatly. We postulate that C4H6N2 replaces the ligation of C=O of C17 ester and C131 keto to Mg atoms sequentially. The two Chl a molecules linked by two weakly interacted Mg…O bonds form a relaxed-dimer. The
structure of the model is essentially similar to that of the primary electronic donor, P680, of photosystem II in high plants and algae. 相似文献
