Abstract：
Inclusive distributions of longitudinal momentum and energy ((S/β) (dσ/dx_p⁾and (S/β) (dσ/dx_E⁾) in a quark jat for e⁺ e^- collidiny is calculated (√S～7GeV), fased onrandomly producing wee quarks and phase-space eonsideration. Excellent fits areobtained. In addition, a two-particle correlation dσ/(dx_IEdx_2E⁾ is also given, which ex-pects experimental tests.
