运行结果示例
模拟足球比赛门前抢点射门数据统计
本场比赛共产生 40 次门前抢点射门
=============================================
足球比赛门前抢点射门统计报告
=============================================
一、总体统计对比：
-------------------------------------------
队伍 | 总射门 | 射正 | 进球
-------------------------------------------
主队 | 18 | 7 | 3
客队 | 22 | 9 | 4
二、详细统计对比：
-------------------------------------------
主队 | 射门: 18 | 射正: 7 | 进球: 3 | 被封堵: 5 | 射偏: 6 | 转化率: 16.7%
客队 | 射门: 22 | 射正: 9 | 进球: 4 | 被封堵: 6 | 射偏: 7 | 转化率: 18.2%
三、门前抢点区域分布：
-------------------------------------------
区域 | 主队 | 客队
-------------------------------------------
小禁区 | 5 | 7
点球点附近 | 6 | 8
6码区 | 4 | 3
禁区内 | 3 | 4
四、数据分析结论：
-------------------------------------------
客队在门前抢点方面表现更出色！
客队创造的机会更多，射门更具威胁性
客队抢点效率更高（18.2% vs 16.7%）
五、射门时间分布（每15分钟）：
-------------------------------------------
时间段 | 主队射门 | 客队射门
-------------------------------------------
1-15分钟 | 3 | 4
16-30分钟 | 2 | 3
31-45分钟 | 4 | 5
46-60分钟 | 3 | 4
61-75分钟 | 3 | 3
76-90分钟 | 3 | 3 核心功能说明
- 数据模拟：随机生成两队的前门抢点射门数据
- 区域分类：区分小禁区、点球点附近、6码区等门前区域
- 统计指标：总射门、射正、进球、封堵、射偏和转化率
- 时间维度：按15分钟区间统计射门频率
- 数据分析：自动生成战术分析结论
这个案例可以用于足球比赛数据分析和战术研究。
