他指出，政府债券供应量持续增加，以及央行回购计划（这使政府债券收益率维持在较低水平）的终结，是该公司收缩在美国和英国的投资敞口的主要原因。

Whilst this is a negative as it implies greater bond supply, we believe that the over riding weak economic growth picture as well as the need to keep official interest rates low will be the key driver of bonds and that until growth recovers bond yields are unlikely to rise.

虽然有提高债券供应量的可能，但我们相信经济增长疲弱的背景以及维持较低官方利率的需要将会成为债券价格的主要驱动力。并且，在增长恢复之前，债券收益率不太可能上升。

At the same time, pro-active fiscal policy, regulatory bodies pushing development of the bond market's intentions quite clear, convertible bonds, medium-term notes, corporate bonds, such as New detachable emerging debt; 4 trillion economic stimulus package Added The fiscal deficit will continue to increase market supply of bonds, the bond market has undoubtedly provide more investment opportunities.

他指出，政府债券供应量持续增加，以及央行回购计划（这使政府债券收益率维持在较低水平）的终结，是该公司收缩在美国和英国的投资敞口的主要原因。

The lack of variation in the term structure of government bond results in the short of bond supply function, while the market mechanism will result in compensation for the lack of novelty features, such as central bank bills and the black market.

国债发行品种期限结构不全，必然要导致国债功能供给缺失，这时市场机制将催生新生事物补偿缺失功能，如央行票据和国债黑市的出现等。

Studied linear demand function respectively (the otherness that catenary bond supplies to design below Linear) and hypothesis of stretch demand function, use price rebate strategy to design supply mechanism of catenary cooperation bond.

分别研究了线性需求函数与弹性需求函数假设下供应链契约设计的差异性，并利用价格折扣策略来设计供应链协作契约机制。

The results show that the torsion energy and van der Waals interaction energy are the main types of energy and the substitution group has a great effect on the total energy of molecular. The aliphatic substitution would lead to the increase of total energy, while the aromatic substitution would lead to the decrease of total energy. The calculated results of bond length show that the bond length of aliphatic C—C is longer than that of aromatic C—C, which indicates that the rupture of aliphatic C—C is easier than that of aromatic C—C on heating.

研究结果表明，扭转能和范德华能是分子中的主要作用力，取代基对体系能量有明显影响，烷基取代基使体系能量增加，而苯基取代基使体系能量降低；脂肪C—C键长比芳香C—C键长长，说明脂肪C—C在受热过程中比芳香C—C更容易断裂分解。

The regularities of the substitution effects of the electron-pushing group and the electron- withdrawing group on the electronic structures and the related properties of the complexes, e.g. the energies and the compositions of some frontier molecular orbitals, the spectroscopy properties, the atomic net charge populations on main ligands, the coordination-bond lengths and the coordination-bond angles of the complexes, etc. have been investigated.
