在netlogo模型库中有一个virus on a network，里面有一个代码to spread-virus
W e1 d2 n) S. O ask turtles with [infected?]
4 n8 Z% Q, N: O+ U [ ask link-neighbors with [not resistant?]( _$ ~; }6 W. G5 G0 b, q9 X
[ if random-float 100 < virus-spread-chance2 p! J+ }' I! a8 Q9 _6 O2 w
[ become-infected ] ] ]
& @7 ]0 P' Y; S; Q5 l( oend
1 o7 x/ W# h; k! h% R这里为什么virus-spread-chance大于random-float 100,就可以判断出become-infected呢？
* l) O( z! L& ]/ Xto do-virus-checks- h; l! T9 T- S5 W6 j6 o. }+ ~# C& I
ask turtles with [infected? and virus-check-timer = 0]! y: C+ I6 s8 p+ v+ ^2 I

下面同样这个问题不明白
