Both networks have a strong degree-strength correlation but neither of them has a significant assortative or disassortative property.

结果发现两种网络均有很强的度和强度相关性，但是同配异配性质并不明显。

Furthermore, there exists a minimum congestion with adaptive greed extent. Proposing the concept of congestion flexibility to represent what extent the congestion could be reduced, we also find that congestion in assortative network is less flexible than its disasss...

我们提出采用拥塞弹性的概念来表征网络拥塞可以降低的程度，进而发现相比于同配网络，异配网络更具拥塞弹性，而就幂率网络而言，幂率系数约为2.4时呈现拥塞弹性最大值。

The results showed that precursor feeding (phenylanine, sodium acetate and benzamide) and mixed sugar as production medium resulted in significant increase of taxol production not only in the one-liquid-phase cultures of Taxus chinensis var. mairei but also in the two-liquid-phase cultures. And the integrated function of precursor feeding and mixed sugar in the two-liquid-phase cultures gave more significant increase of taxol production significant increase of taxol production, which was four times more than that of the control (the one-liquid-phase culture without precursors and mixed sugar).

结果表明前体饲喂（苯丙氨酸，醋酸钠和苯甲酰胺）和蔗糖与麦芽糖配伍作为生产培养基糖源不仅对红豆杉细胞悬浮培养，而且对其两液相培养的紫杉醇产量提高均有明显的促进作用，与对照组相比，在南方红豆杉细胞两液相培养中，采用前体饲喂和蔗糖与麦芽糖配伍作为生产培养基糖源，紫杉醇产量提高4倍多。

Based on studies of RCM reaction of 50 and CM reaction ofacrylonitrile with 1-octene or 1-decene catalyzed by pyridine derivative-coordinatedruthenium benzylidene complexes, it can be concluded that ruthenium benzylidene complexwith the more labile dissociating ligand exhibits the higher initial activity and better catalyticperformance.

New ruthenium benzylidene complexes benzylidene[1,3-bis(2,6-dimethylphenyl)-4,5-dihydroimidazol-2-ylidene] [k~2-diphenylphosphinoacetato] monochlororuthenium (46), benzylidene[1,3-bis(2,6-dimethylphenyl)-4,5-dihydroimidazol-2-ylidene][k~2-3-propionato]monochlororuthenium (47), benzylidene[1,3-bis(2,6-dimethylphenyl)-4,5-dihydroimidazol-2-ylidene] [k~2-2-benzonato]monochlororuthenium (48) featured five-membered, flexible six-membered and rigidsix-membered chelating rings respectively are prepared by reactions of complex 41 withcorresponding sodium phosphino-carboxylates. It is confirmed by X-ray crystallographicanalysis that the coordination geometries of complexes 46 and 47 are distorted squarepyramids with phosphino-carboxylate ligands chelating to ruthenium, and the coordinationbetween ruthenium and benzylidene ligands are strengthened.
