摘要翻译：
金融市场中的两相行为实际上是指条件概率由单峰分布向双峰分布转变的分叉现象。本文对恒生指数中的分叉现象进行了细致的考察。观察到财务指标中的分叉现象不是普遍存在的，而是在一定条件下的特异现象。当绝对增量分布的幂律指数在1~2之间，适当的周期时，这种现象才出现。对随机生成的时间序列的模拟表明，分叉现象本身服从绝对增量的统计，因而不能反映本质的金融行为。但即使在绝对增量相同的分布下，分叉现象发生的范围从真实市场到人为数据也相差甚远，可能反映了一定的市场信息。

英文摘要：
  The two phase behavior in financial markets actually means the bifurcation phenomenon, which represents the change of the conditional probability from an unimodal to a bimodal distribution. In this paper, the bifurcation phenomenon in Hang-Seng index is carefully investigated. It is observed that the bifurcation phenomenon in financial index is not universal, but specific under certain conditions. The phenomenon just emerges when the power-law exponent of absolute increment distribution is between 1 and 2 with appropriate period. Simulations on a randomly generated time series suggest the bifurcation phenomenon itself is subject to the statistics of absolute increment, thus it may not be able to reflect the essential financial behaviors. However, even under the same distribution of absolute increment, the range where bifurcation phenomenon occurs is far different from real market to artificial data, which may reflect certain market information.
