在netlogo模型库中有一个virus on a network，里面有一个代码to spread-virus+ f% r2 y3 \' J+ H; T- h
ask turtles with [infected?]4 y9 ]% P/ e+ o! g9 A7 _# C
[ ask link-neighbors with [not resistant?]
6 T6 L, h6 I+ L [ if random-float 100 < virus-spread-chance k4 J% r9 z0 |: Y
[ become-infected ] ] ]
9 z+ v1 C3 U4 X \3 q5 Y+ Q8 hend) x8 Y2 p7 y5 f7 O% m* o5 T
这里为什么virus-spread-chance大于random-float 100,就可以判断出become-infected呢？
