The length of certain bond and the number of conjugate double-bond affected OWF〓 greatly, OWF〓 changed linearly with the change of bond length (for planar azobenzene derivatives and cyanine derivatives) and the change of conjugate double-bond number (for conjugate alkene,β-carotene and lycopene).

3键长和共轭双键数对OWF〓有较大的影响，OWF〓随键长（如平面型的偶氮苯衍生物、菁类和氧杂菁类等）和双键数（如共轭烯烃类、β—胡萝卜素和番茄红素等）的变化而线性变化。

The length of certain bond and the number of conjugate double-bond affected OWFπ-π greatly, OWFπ-π changed linearly with the change of bond length (for planar azobenzene derivatives and cyanine derivatives) and the change of conjugate double-bond number (for conjugate alkene, p-carotene and lycopene).

3键长和共轭双键数对OWF_有较大的影响，OWF_随键长(如平面型的偶氮苯衍生物、菁类和氧杂菁类等)和双键数(如共轭烯烃类、β—胡萝卜素和番茄红素等)的变化而线性变化。

Because of embedded option, the cash flow of callable bond is not certain. Fortunately, it has the same future cash flow as the portfolio of one long noncallable bond and one short call option on the callable payments. So under a nonarbitrage condition, the value of callable bond equals the difference of the value of noncallable bond and call option.

由于内嵌看涨期权的存在，可赎回债券的预期现金流事先并非确定，但因其未来的现金流表现与持有可比普通债券和卖空看涨期权的投资组合相同，故而可赎回债券的价格在无套利条件下应等于可比普通债券减去看涨期权的差值，也就是说用于普通债券的一般定价和度量方法并不适用于此种特殊的选择权债券。

The paper prices bond and bond option, analyzing dynamic interest rate, regime-switching and option pricing. According to the affection of regime-switching to interest rate derivative pricing, the paper deduces the partial differential equation of bond pricing with Ito lemma, and obtains characteristic function and recursion equation of bond option.

从利率动态变化、结构转换和期权定价三个方面进行分析，对结构转换下的债券和债券期权进行定价，考虑了结构转换对利率衍生物定价的影响，利用Ito引理获得债券定价的偏微分方程，并得到债券期权定价的特征函数与递归等式。

Mature markets, the bond market and the stock market is often a seesaw, the stock market disaster must achievements bond hot, and now into the rate cut cycle, the relative rise in bond yields, and therefore more and more hedge funds seek to enter the bond market.

成熟的市场，债券市场和股市往往是跷跷板，股市灾害必须取得债券热，进入降息周期，债券收益率相对增加，因此越来越多的对冲基金现在试图进入债券市场。

This paper prepares to probe into the characteristic and regularity of Convertible Bond running in our capital market, to pull Convertible Bond into successful practice by virtue of the link of the theories of Convertible Bond, such as Convertible Bonds factors-planning, the choice of issuing time, the influence to financial structure, pricing-model, etc, and the running situations of the issued Convertible Bond.

本文拟就可转换债券的重要理论，如可转换债券的股性和债性、可转换债券的要素设计、发行时机的选择、对财务结构的影响、定价模型、价值构成、投融资风险等，再结合我国已发行的可转换债券的运行情况，以探讨可转换债券在我国资本市场运行的特点和规律，以推进可转换债券在我国的成功实践。

The results show that the major contribution to DOS of Mg and Pb are the 2p orbit of Mg and the 5d orbit of Pb, followed by the 3s orbit of Mg and the 6p orbit of Pb, the 6s orbit of Pb is the smallest one. There are a large number of charges around Mg, it has the characteristics of typical metal bond. Mg and Pb share some charges to form covalent bond, but the distortion of the charge at the junction is little; the proportion of covalent bond is less than the metal bond, Mg2Pb is semimetal. The elastic modulus and shear modulus of Mg2Pb are 68.6 and 27.9 GPa, respectively. Based on Pugh empirical criterions and Poisson's ratio, Mg2Pb is brittle in nature.

结果表明：Mg和Pb对态密度的贡献主要是Mg的2p轨道和Pb的5d轨道，其次为Mg的3s轨道和Pb的6p轨道，Pb的6s轨道贡献最小；在Mg原子周围有大量的电荷存在，呈典型的金属键特征，Mg、Pb之间存在共用的电荷，有较强的离域性，以共价键形式存在，但交界电荷的畸变不大，故共价键所占比例较少，金属键所占比例较大，Mg2Pb化合物呈半金属性；Mg2Pb的弹性模量和切变模量分别为68.6和27.9 GPa，Pugh经验判据和泊松比均表明Mg2Pb具有脆性。
