【正文】 satile curve is time, the ordinate is constriction power. Take notes for the pulsatile curve of toad heart that exposed can know the rhythmic pulsatile cycle of the toad heart is from fig 1 which show the cardiac rhythmic pulsatile curve of the toad which was exposed the heart just now. There are two waves in each cycle, one is atria wave, the other is ventricle wave. The atria wave is and the ventricle wave is . The constriction power of atria is less than that of ventricle. The amplitude of constriction power of ventricle is the 2 times of the atria. Fig. . It is rhythmic pulsatile curve of the toad without magic stimulation. The constriction power of toad heart would bee weaker after the toad heart was exposed for a while. At the same time,atrium wave and ventricle wave can not be already distinguished. Heart contracting amplitude were reduced obviously, do not go to the half of original atrium wave. The rhythmic pulsatile cycle of the toad heart is still . Fig. . It is the weak pulsatile curve of toad without magic stimulation. But we can distinguish the atria wave and the ventricle wave again after giving the toad heart a magic stimulation on following picture. And the amplitude of ventricle waves is more than that of the single wave. The rhythmic pulsatile cycle of the toad heart is still . There were six toads as experiment animal in our exposing heart a time, the rhythmic pulsatile curve all became single peak curve. Stimulate them when the single amplitude was . Noted the data and analyze them. Following is the pulsatile curve of the six toads recorded which were stimulated by magic field. Fig. . It is the pulsatile curve of the fist toad which heart was stimulated by magic field. Fig. . It is the pulsatile curve of the second toad which heart was stimulated by magic field. Fig. . It is the pulsatile curve of the third toad which heart was stimulated by magic field. Fig. . It is the pulsatile curve of the fourth toad which heart was stimulated by magic field. Fig. . It is the pulsatile curve of the fifth toad which heart was stimulated by magic field. Fig. . It is the pulsatile curve of the six toads which heart was stimulated by magic field. V. COMPARISIION Record ventricle wave amplitude and atrium wave amplitude of the six toads after magic stimulation. Table. . From Toad1to Toad6 expressed the six toads which was stimulated by magic field. The Toad0 expressed the toad which was not stimulated by magic field. Toad7 expressed the toad which pulsated weakly. amplitudes of atria wave amplitudes of ventricle wave Toad0 Toad1 Toad2 Toad3 Toad4 Toad5 Toad6 Toad7 Express the toad which was not stimulated by magic withToad 0, and express the toad which pulsate weakly withToad 7. Make histogram to contrast by these data. The first histogram was made by the data of the pulsatile amplitudes of when toad was not gets stimulate and pulsate weakly, as well as the pulsatile amplitude of the fist stimulated toad. After magic stimulation, amplitudes of atria wave and ventricle wave were higher than single wave of weak heart. But it is more low than the amplitudes of heart when just exposes obviously. Fig. . The histogram was make by the amplitudes of the toad exposed heart justly and the toad which stimulated by magic field, the toad which pulsate weakly. The Toad 0 expressed the toad which was not stimulated by magic field. The Toad 1 expressed the fist toad which was stimulated by magic field. The Toad 7 expressed the toad which pulsated weakly. Make histogram respectively with the data of amplitude of each toad stimulated by magic field and the amplitude of single wave. Make histogram with the data of amplitudes of six toads stimulated by magic field, and pare them. Fig. . The histogram was made by the amplitudes of the first toad which was sti
