Abstract: This invention is about an editable intelligent 2-dimensional bar code which allows vacant code assignment and allows the users to modify the content for certain purposes at any time; It also has video, audio, image and character functions; The editing interface is clear and simple. The intelligent 2-dimensional bar code has an independent editing and operating platform and background so that it easy to edit and operate. Moreover, it has two editing modes, modular mode and free mode. This invention is the first intelligent 2-dimensional bar code that is editable for users. People who are allowed to acquire the information can acquire the latest information by scanning the code.

Abstract: A control method and a control device of an engine are introduced. During the process of the engine controlling, the control unit does the adaptive learning for the actual target value of the feedback of different aims, and following the dynamic spectrogram generation strategy optimizing compares the adaptively learning parameter of the same working status and the same time with the basic spectrogram parameter. If the compared result doesn't meet the condition, then keep the basic spectrogram parameter. And if it meets the condition, then the engine generates the dynamic spectrogram parameter. Based on the dynamic spectrogram combination strategy, the engine combines the basic spectrogram parameter and the dynamic spectrogram parameter generated to the combined spectrogram parameter instead of the basic spectrogram parameter.
