[求助] 帮我翻译一下,看看FR是什么意思 已有1人参与

A daily session consisted of four cycles, each  preceded by a 10-min time out period in which all lights in the chamber were off and responding had no programmed
consequences. Each cycle consisted of two components. The first component was signaled by red stimulus lights and consisted of a FR 18 schedule of food pellet delivery
(Bioserve, Frenchtown, NJ, USA) followed by a 10-s time out. The second component, signaled by green stimulus lights, consisted of the FR 18 schedule of food delivery
combined with a FR 20 schedule of foot shock delivery (1.5–3.0 mA, adjusted for each monkey based on individual performance, 0.25-s duration). Both components were
5 min in duration or ended after the monkey obtained five food pellets or received three foot shocks, whichever occurred first.
Test sessions were conducted once or twice per week. Here, i.v. injections of vehicle or drug were administered in the fifth minute of each time out. In successive cycles,
increasing doses of the test drug were administered using a cumulative dosing procedure. The dependent measure was the average rates of responding (responses/s), calculated by dividing responses by time during components 1 and 2, excluding responding during time outs or reinforcer delivery。

这是用软件直接翻译的吧?意思讲不通啊。
