Abstract: A hybrid power drive system, including a power battery device, a range extender system, and a motor drive system. The power battery device is configured to supply power to the motor drive system. The range extender system includes an engine and a generator. The generator is able to generate power under the driving of the engine to supply the power to the motor drive system and/or charge the power battery device. The hybrid power drive system further includes a vehicle control unit configured to control the engine and/or generator of the range extender system to generate a driving force. The range extender system is mechanically connected to a main coupling mechanism to transmit the generated driving force to a main drive axle of a vehicle by means of the main coupling mechanism to drive wheels on both sides of the axle to rotate. Also provided is a vehicle having the hybrid power drive system.

Abstract: The present invention relates to a method for fertilizing corn in a semi-humid region for one time, and belongs to the field of agricultural fertilization. The method adopts a corn seeding and fertilizing combined machine to sow and fertilize for one time in a semi-humid region. The method realizes nutrient supply throughout the growth of corn without performing top dressing in a later stage. The method improves fertilizer utilization, saves labor cost and improves production and income. The present invention effectively improves ventilation and light transmission conditions in the corn field, eliminates the effect of a stubble of a preceding crop on the emergence of corn, improves uniformity, and reduces nutrient loss.

Abstract: The invention allows the inclusion of cross-talk coupling and other noise in circuit simulation by considering a resultant glitch in more detail than just its peak value. A set of parameters represents the noise, with an exemplary embodiment using a triangle approximation to a glitch based on a set of three parameters: the peak voltage value, the leading edge slope and the trailing edge slope. These values are then used as the input stimulus to a given cell instance in the network in which the resulting propagated noise values, also in a triangle approximation, are determined by a simulation. The results can be stored as a library so that, given the parameters of the input noise and the particular cell, a simulation can determine the propagated noise through a look-up process. To reduce the space requirements of the library, the dimensionality of the look-up tables can be reduced through the introduction of a set of auxiliary functions to offset error from this reduction.

Abstract: The present invention presents techniques for considering whether the effects of cross-talk coupling and other noise exceed the noise tolerance of a circuit. One aspect of the present invention uses a set of parameters to represent this noise. An exemplary embodiment uses a triangle or trapezoidal approximation to a glitch based on a set of parameters: the peak voltage value, the width, the leading edge slope and the trailing edge slope. These values are then used as the input of a library to look up the corresponding noise tolerance parameter set values. In a variation, a set of formulae can provide the noise tolerance parameter set values. In an exemplary embodiment, the noise tolerance parameter set is taken to include the minimum peak value for the noise to be possibly harmful and the minimum width value for the noise to be possibly harmful.
