The amount of cracking in glass around a bullet hole will depend on a number of factors, including the type of glass, the angle at which the bullet strikes the glass, and the velocity of the bullet.
When a bullet strikes glass, it creates a small hole and a ring of cracks around the hole, known as a spiderweb pattern. The amount of cracking around the hole will depend on the type of glass and its thickness. Tempered glass, which is a type of safety glass, is designed to shatter into small, rounded pieces when it is broken, which can help to reduce the amount of cracking. Laminated glass, which is made up of two or more layers of glass with a plastic interlayer, is also less likely to crack than regular glass.
The angle at which the bullet strikes the glass also plays a role in the amount of cracking. A bullet that strikes the glass at a right angle is more likely to create a larger spiderweb pattern than a bullet that strikes the glass at an angle.
Finally, the velocity of the bullet also plays a role in the amount of cracking. A bullet traveling at a high velocity will create more cracking than a bullet traveling at a lower velocity.
In summary, tempered glass, laminated glass, bullet striking the glass at an angle, and lower velocity bullet are less likely to cause a large crack around the bullet hole. [1评]
哈哈搞笑了，我质疑AI，然后AI道歉了，如下
I apologize, I misspoke in my previous answer. The faster the bullet, the smaller the hole will be due to the way the bullet interacts with the glass. At high velocities, the bullet will create a small, clean hole as it travels through the glass. The force of the bullet causes the glass to break cleanly, with minimal cracking around the hole. At lower velocities, the bullet will push the glass around as it travels through it, creating a larger hole and more cracking around the hole.
荷兰首都阿姆斯特丹1月25日启用一座能停放7000辆自行车的水下建筑，它临近中央车站，为骑行者接驳轨道交通提供便利。
据法新社报道，该自行车库于2019年开工建设。施工者将中央车站旁边一片湖水抽干，在湖床上建好自行车库后引回湖水，使它没在水下。这一自行车库有类似传送带的移动步道与地面相连，方便骑行者进出。
该自行车库的设计企业wUrck表示，这一建筑的外墙采用玄武岩等天然石料，质地粗糙，内壁则质轻平滑，在其内部仿佛置身于一个“蚌壳”里。
荷兰负责基建事务的副部长薇薇安妮·海宁在这一自行车库启用仪式上说，在荷兰这个国土面积很小的国家，这座自行车库极大限度利用了空间。
据英国《卫报》报道，荷兰是个自行车数量比人口多的国家，1780万人拥有约2340万辆自行车，自行车是阿姆斯特丹和其他一些城市居民的主要出行方式之一。
阿姆斯特丹现有约90万辆自行车。不少阿姆斯特丹人骑车到中央车站，在那里乘列车去往目的地。水下自行车库的建成将腾出大片地面空间，以打造宽敞整洁的环境，也使骑行者不再为找不到停车位头疼。
阿姆斯特丹IJ港旁边也在建一座大型自行车库，预计下月投入使用，可停放4000辆自行车。这座自行车库建在河中人工堆造的洲屿上。
