On the basis of studying recognition method for image of electret condenser microphone, this paper presents an improved BP learning algorithm for recognizing the image features using neural network, and the method for adjusting momentum vector and learning rate is discussed.

在研究对驻极体麦克图像识别方法的基础上，本文提出了一种用改进的BP神经网络进行图像特征的识别和学习算法，并给出了动量系数和学习率的调整方法。

An analytical model was built up on the jet deflection in the crossflow by applying the theorem of momentum, which takes full account of mixing between the upstream fluid and burner jet, and of the total pressure difference between the two sides of the jets. Through analysis of this model, experimental study and numerical simulation, effects of the nozzle spacing ratio, width of the furnace corner, width of the nozzle and imaginary circle diameter on the aerodynamic field in the furnace were obtained.

本文综合考虑了炉内旋转气流与燃烧器射流的混合和燃烧器射流向火侧与背火侧的全压差等因素，应用动量定理建立了横向气流中射流偏转的分析模型，并结合冷态模化试验和数值模拟计算，得到了燃烧器间隙率、炉膛切角、喷口宽度和假想切圆直径等因素对炉内空气动力场影响的规律。

Once we fall, however slightly, into immoderation, momentum gathers and we can be lost to whim.

一旦我们失去节制，不管多么轻微，惯性便形成了，我们就有可能在奇想中迷失。
