In flask shaking culture, the output of CDEP-1 increased in parallel with the accumulation of biomass during the logarithmic growth phase and reached the peak value in stationary growth phase, then fleetly decreased in decay period.

摇瓶发酵结果表明，在对数生长期，随着菌体生物量的增加，CDEP-1产量上升，二者呈一定的平行关系；当菌体生长到稳定期，CDEP-1产量继续上升，并达到产酶高峰；此后，随着菌体生长的衰退，CDEP-1产量出现快速下降趋势。

It was supposed that the dynamic moving process of the stock price and the return was driven by Geometry Brownian Motion and the lognormal distribution respectively. Takinginto account the riskneutral environment, we got a closedform analytical formula for deferred arithmetic asian options by the method of Taylor expansion of the stochastic integral formula within the terminal payoff. Furthermore, with the series definition of the definite integral, we transferred the continuous problem into a discrete one which is simpleenough to figure out. Meanwhile we tested the accuracy of the formula with the Monte Carlo simulation as a benchmark and the result shows that the formula can be utilized to price the related financial derivatives.

在标的价格服从几何布朗运动、收益服从对数正态分布的前提下，通过风险中性定价原理，对到期损益中的随机积分进行任意次Taylor近似，并由级数定义将此连续问题离散化，给出了延期算术平均亚式期权封闭形式的解析定价公式，并与Monte Carlo模拟得到的价格作为标尺对得到的公式进行精确性检验，结果表明，所得公式可以应用到金融实务中对此类衍生品定价中。
