The BP neural network used in the temperature characteristic of the boundary film on the screw-nut pairs surface in the wear-self-compensation system was established.

本文用双隐层BP人工神经网络建立了丝杆螺母副表面边界膜温度特性的磨损自补偿数学模型。

The network could predict the effects of the temperature on the boundary film strength. the network trained with the L-M rule were quick in convergence and small in error.

该模型可用于准确地预测温度对边界膜强度的影响。并采用L - M规则进行神经网络学习训练可使网络收敛快，误差小。

This model takes into account both the diffusion resistance of the membrane phase in non-steady state and the diffusion resistance of the external phase boundary film and the membrane leakage.

该模型不仅考虑了非稳态下膜相扩散阻力，而且还考虑了外相边界层的扩散阻力及膜破裂。

if that's something you're familiar with - in which the interaction of real people with what are called "Toons" in that film is part of the film's pleasure. The boundary between different levels of reality is crossed.

如果你们对这个比较熟悉的话,在电影里一个被称为“Toons“的卡通形象和真人互动“,这是那部电影的好玩之处,在那里不同层面现实的边界交叉了。
