摘要：

A search has been made for strange matter with a CR-39 track-etch detector with an array of 160 m2, exposed for 8 months at mountain altitude. The non-observation of penetrating tracks places a new stringent upper limit on the flux of strange matter, 2.2 x 10(-14) cm-2s-1sr-1 (90% confidence level) in the velocity range-beta (= v/c) > 4 x 10(-5).
