请教一个go指针问题

type field struct { name string } func (p *field) print() { fmt.Println(p.name) } func main1() { data := []field{{"one"}, {"two"}, {"three"}} for _, v := range data { go v.print() } time.Sleep(3 * time.Second) } func main2() { data := []*field{{"one"}, {"two"}, {"three"}} for _, v := range data { go v.print() } time.Sleep(3 * time.Second) } // main1输出 three three three // main2输出 one two three 感觉像理解了，但是还是没彻底弄懂，有人能再解释下吗？
