Numerical simulation by Matlab for the new hypocycloid energy transformation mechanisms was done by means of the four-order Runge-kutta's method. The result shows that the simple harmonic and rectilinear motion of piston in the new mechanism make the engine working more stable. The peak acceleration is around 25% lower in the new mechanism than that in the conventional slider-crank mechanism. And the output speed is much higher at the same identical mean effective pressure and same load torque. And then the output power of the engine is improved.

基于四阶Runge-Kutta法，运用MATLAB进行了仿真验证，结果表明，新型内摆线能量转换机构的活塞做完全简谐直线运动，运动更加平稳；活塞加速度峰值比传统曲柄滑块机构小25%；在相同的气缸平均等效压力和负载转矩下，具有较高的输出转速，提高了内燃机的输出功率。

The results shown that there will be great potential capacity to increase grain output in production, and the grain yield are positive related with the amount of fertilizer markedly as a whole, but there have been imbalance and inconsequence in using of fertilizer. It is essentially important to improve fertilizer use efficiency for save resources as well as increase yield. To increase grain output should to arrange fertilizer by planning as a whole rationally rather than to increase its amount.

结果表明，藁城市粮食生产还有很大的增产潜力，总体上粮食产量与化肥的投入仍然呈显著正相关关系，但是，目前实际生产中化肥施用量存在极其严重的不平衡和不合理现象，所以增施化肥已不再是增产的主要措施，而合理统筹、提高化肥的利用率至关重要，是节能增效的重要措施。

Performance index based on the error between the actual output and the predicted output is employed to generate the switching logic.

在每一采样时刻根据指标函数与实际对象最接近的模型，并将基于此模型的控制器切换为当前控制器。

This simple definition ignores the fact that amplifier output impedance usually varies considerably across the audio band, increasing with frequency as the negative feedback factor falls; this indicates that the output resistance is actually more like an inductive reactance.

这个简单的定义忽略了功放输出阻抗通常是随着音频带而变化，负反馈因素降低的时候频率也增加这一事实。这就意味着输出电阻实际上更像是一个电感电抗。

The effects of the initial values and the network approximation error using neural network model composed of feedforward neural net and delayed output feedback in the approximation of NARMAX system are studied, and a conclusion is drawn that under some weak conditions the output of the network model has little difference from that of the actual system.

研究了用带有延迟环节的前馈网组成的网络模型逼近NARMAX系统时网络逼近误差及运行初始误差对网络模型输出的影响，指出在一些弱的条件下网络模型输出与实际系统输出间相差不大。

A frequency divider, comprises: an inverting unit comprising an input, and an output; and a plurality of switch inverters in series, having at least a first switch inverter and a last switch inverter; each switch inverter comprising two inphase switches, in which the first switch inverter is connected to the output of the inverting unit, and the last switch inverter is connected to the input of the inverting unit; wherein the two inphase switches of each of the switch inverters are respectively supplied by a first voltage and a second voltage, any two of the adjacent switch inverters are respectively controlled by two inverted clocks, thereby the two inphase switches are selectively turned on synchronously and turned off synchronously.

反相单元包含输入端以及输出端；串联的多个切换反相器，具有至少一第一切换反相器以及最终切换反相器，每一切换反相器包含两个同相开关，其中第一切换反相器连接于反相单元的输出端，且最终切换反相器连接于反相单元的输入端；每一切换反相器的同相开关分别由第一电压与第二电压供电，任何两个相邻的切换反相器分别受控于两个反相时钟，因此该两个同相开关是选择性同步开启及同步关闭的。

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

输入和输出可能会超过额定电压的输入和输出，如果额定电流得到遵守。

So the growth of economic output can be directly summed up in two parts: First, the growth of input, second, the growth of output per unit input, namely the growth of productivity.

所以增长的实现直接归结为两部分：一是投入的增长，二是单位投入的产出的增长，即生产率的增长。

The forecast data of grey prediction GM (1, 1) were used as the input variable of BP neural network, the actual output were as output variable.

将GM(1，1)预测模型的预测值作为BP神经网络的输入变量，实际值作为输出变量进行神经网络训练。

In this paper, the optimal output-tracking problem of dynamic input-output system is discussed.
