【摘要】 在超对称理论上发展出的超弦理论假设所有的基本粒子（诸如电子、夸克及传递相互作用的玻色子）都是一维延展体——弦。用超对称的弦模型代替以往的点模型,将对涉及10^-33～10³⁰厘米尺度范围的物理理论产生深刻的影响。更多还原

【Abstract】 The superstring theory is based on the dynamics of string-like fundamental quanta rather than the pointlike quanta of more familiar relativistic "point field theories" such as Yang-Mills gauge theory or general relativity. In these theories the observed fundamental particles, such as the leptons and quarks, may arise as the ground states of a string.更多还原
