Thermal sensitive MnZn ferrite is a kind of soft magnetic ferrite material with lower Curie temperature (Tc) and can be used to make many kinds of magnetic thermal sensitive sensors with high sensitivity. In this paper, the relation between the composition of thermal sensitive ferrite and TC was studied. It was found that TC changes linearly with ZnO extent when the content of Fe2O3 is fixed. Based on lots of experiments, an experimential formula to determine was given out.

It has been reported that attending to stimuli in visual modality can spread to task-irrelevant but synchronously presented stimuli in auditory modality,a phenomenon termed the cross-modal spread of attention,which could be either stimulus-driven or representation-driven depending on whether the visual constituent of an audiovisual object is further selected based on the object *** stimulus-driven spread of attention occurs whenever a task-irrelevant sound synchronizes with an attended visual stimulus,regardless of the cross-modal semantic *** present study recorded event-related potentials(ERPs) to investigate whether the stimulus-driven cross-modal spread of attention could be modulated by audio-visual emotional congruency in a visual oddball task where emotion(positive/negative) was *** results first demonstrated a prominent stimulus-driven spread of attention regardless of audio-visual emotional congruency by showing that for all audiovisual pairs,the extracted ERPs to the auditory constituents of audiovisual stimuli within the time window of 200–300 ms were significantly larger than ERPs to the same auditory stimuli delivered ***,the amplitude of this stimulus-driven auditory Nd component during 200–300 ms was significantly larger for emotionally incongruent than congruent audiovisual stimuli when their visual constituents’ emotional valences were ***,the Nd was sustained during 300–400 ms only for the incongruent audiovisual stimuli with emotionally negative visual *** findings suggest that although the occurrence of the stimulus-driven cross-modal spread of attention is independent of audio-visual emotional congruency,its magnitude is nevertheless modulated even when emotion is task-irrelevant.

This study analyzes and gives advice on the relevant folk culture of Lingnan from the perspective of digital protection and inheritance, through the implementation of multimedia interaction scenarios and interaction processes, the historical and cultural implications of the Lingnan heritage, the stories of local folklore and the simulation interaction of the production process are realized. This paper proposes a visual and realistic concept of Lingnan culture, and uses the multimedia design method of image animation, audio and other multimedia design methods to sense the virtual reality design, aiming at the historical background, folk culture, craft culture, business culture and so on. The core is vividly communicated to the public. Bringing the Lingnan people a more immersive and authentic cultural experience.
