The results indicate that the ANN structure and the training sample have some impact on the prediction precision. The real time measured power as input will improve the precision of 30 min ahead prediction, however will decrease the precision of 1h ahead prediction. The results which using the atmospheric data at all different heights as input have a higher accuracy when compared with the results using hub height data only. The designed ANN can forecast the error band.

研究结果表明，神经网络的结构和输入样本对预测结果有一定的影响；实测功率数据作为输入可以提高提前量为30 min的预测精度，而对提前量为1 h的预测精度会降低；把不同高度的数据都作为神经网络的输入比只采用轮毂高度数据的预测精度高；设计的神经网络能够对误差带进行预测。

All kinds of errors that influence load sharing characteristics of gear system have been given, mainly including manufacturing and assembly error of each gear component's axis and each bearing's axis, tooth thickness error. The formulas of equivalent mesh error have been derived.

确定了影响行星齿轮传动系统均载特性的各类误差，主要包括：各个齿轮构件的中心轴线制造和安装误差、轴承中心轴线的制造和安装误差、行星架的制造误差、齿轮的齿厚偏差。

Magflow meters have found application in the process control industries (chemical, food-and-beverage, pulp and paper, water treatment) because they have low measurement error (0.2% of reading attainable) over a broad range (typically 30:1) and they require no moving parts (unlike turbine meters or paddlewheel technology) or flow restriction (unlike differential pressure meters) to operate.

因其在一宽广范围（通常为30：1）内具有低的测量误差（可达到读数的0.2％）且其在工作时不需要使用运动部件（不同于汽轮计或桨轮技术）或流量限制，磁性流量计已在过程控制行业（化学、食品及饮料、纸浆及造纸、水处理行业）中得到应用。

" Yes , I have to admit I have been in error about that."

是的，我得承认在这点上我弄错了。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
