    摘要： Embodiments of the present disclosure provide a method, a system and a computer readable storage medium for circuit simulation, comprising: partitioning circuit into a subcircuit-1 and a subcircuit-2 which are connected through at least one port; generating equivalent circuit of subcircuit-1 based on port current/port voltage, subcircuit-1 port voltage under port open-circuit condition/subcircuit-1 port current under port short-circuit condition, and impulse-response of subcircuit-1 port voltage to port current/impulse-response of subcircuit-1 port current to port voltage; simulating a simplified circuit comprising the subcircuit-2 and the equivalent circuit. Comparing with prior art, this disclosure reduces circuit scale by equivalence of linear portion of circuit. Thereby computation amount for circuit simulation is reduced and the computation time for circuit simulation is shortened.

    摘要： The invention relates to a method for measuring a distance between a coordinate indicator and a coordinate input device, which belongs to the technical field of computer peripheral equipments. The method comprises the steps of measuring an actual amplitude of an output signal of a receiving coil in the electromagnetic induction plate by a measurement circuit in the electromagnetic induction plate; determining a distance between the coordinate indicator and the coordinate input device in accordance with the actual amplitude of the output signal, a nominal amplitude of the output signal, and a preset reference amplitude of signal. In the present invention, the distance between the coordinate indicator and the coordinate input device is determined by converting an actual amplitude of the output signal of the receiving coil at one time to a nominal amplitude of the output signal normalized by a reference amplitude of signal, which overcomes the defect of the prior art which can not indicate a distance between the coordinate indicator and the coordinate input device.

    摘要： The present invention relates to a method of checking model planes entering into a dive and an anti-dive method. Operating model planes necessitates a certain kind of skills. As regards a beginner, plane crashes often occur due to improper operations. The present invention provides a method of checking planes entering into a dive, comprising steps of: installation of a first optical sensor in the upper part of the plane, with its installation angle upwardly intersecting with the forward direction of the plane as α degrees that checks light intensity and outputs a first checked optical signal; installation of a second optical sensor in the bottom part of the plane, with its installation angle downwardly intersecting with the backward direction of the plane as β degrees which checks light intensity and outputs a second checked optical signal; comparison of the first checked optical signal with the second checked optical signal, and when the difference between the light intensity represented by the first checked optical signal and that represented by the second checked optical signal is smaller than a threshold of light intensity differences, a warning signal to the effect that the plane has entered into a dive is sent out. Moreover, an anti-dive method and device for planes are also provided.
