摘要翻译：
本文提供了Di Nunno等人条件的新版本。(2003)，Ankirchner和Imkeller(2005)和Biagini和ksendal(2005)证明了一类连续随机过程的半鞅性质。与我们的前人不同，我们的建模框架建立在投资组合比例的概念上，它给出了主要定理的一个简短的独立证明，以及一个反例，表明我们的结果的类似物在不连续的环境中不成立。

英文摘要：
  This paper provides a new version of the condition of Di Nunno et al. (2003), Ankirchner and Imkeller (2005) and Biagini and \{O}ksendal (2005) ensuring the semimartingale property for a large class of continuous stochastic processes. Unlike our predecessors, we base our modeling framework on the concept of portfolio proportions which yields a short self-contained proof of the main theorem, as well as a counterexample, showing that analogues of our results do not hold in the discontinuous setting.
