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。

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。
