The view that phosphocreatine was the direct source of energy for muscular contraction lasted only a few years . 认为磷酸肌酸作为肌肉收缩直接能源的观点，流行了不过数年。

The changing tendencies of the relative contents of phosphorous contained substances have been detected by in - vivo " p magnetic resonance spectroscopy ( in - vivo " p mrs ) during the whole hatching process . in - vivo ] p mrs proved the catabolism of adenosine 5 ' - triphosphate ( atp ) , phosphorous ester and phosphocreatine ( pcr ) when the embryo dead . the results could be used to deduce the conversion of phosphorous contained metabolites during the chicken embryo developed 用活体核磁共振定域氢谱( in - vivohmagneticresonancespectroscopy , in - vivohmrs )对胚胎发育过程中羊水和蛋白、蛋黄的成分进行了分析；用活体磷谱( in - vivo ’ ’ pmrs )的方法分析了在整个胚胎发育过程中含磷代谢物的相对含量随时间的变化，表明了磷脂类物质及三磷酸腺苷( atp ) 、磷酸肌酸( pcr )在此过程中的变化及可能的相互转化的趋势，胚胎死亡后的磷谱也证明了磷脂类物质及三磷酸腺苷( atp ) 、磷酸肌酸( pcr )在死亡过程中降解为无机磷的现象。
