Metaphorically, a snowball effect is a process that starts from an initial state of small significance and builds upon itself, becoming larger (graver, more serious), and also perhaps potentially dangerous or disastrous (a vicious circle), though it might be beneficial instead (a virtuous circle). This is a cliché in cartoons and modern theatrics and it is also used in psychology.

从隐喻的角度来说，滚雪球效应是一个过程，它从最初的微不足道的状态开始，然后继续发展，变得更大(更严重，更严重) ，也可能是潜在的危险或灾难性的(恶性循环) ，尽管它可能是有益的(良性循环)。这是动画片和现代戏剧中的老生常谈，也是心理学中的常用语。

The common analogy is with the rolling of a snowball down a snow-covered hillside. As it rolls the ball will pick up more snow, gaining more mass and surface area, and picking up even more snow and momentum as it rolls along.

常见的比喻是一个滚动的雪球下雪覆盖的山坡。在滚动过程中，球会吸收更多的雪，获得更多的质量和表面积，并且在滚动过程中吸收更多的雪和动量。

In aerospace engineering, it is used to describe the multiplication effect in an original weight saving. A reduction in the weight of the fuselage will require less lift, meaning the wings can be smaller. Hence less thrust is required and therefore smaller engines, resulting in a greater weight saving than the original reduction. This iteration can be repeated several times, although the decrease in weight gives diminishing returns.

在《航空航天工业奖，它被用来描述原始减肥中的乘法效应。减少机身的重量将需要较少的升力，这意味着机翼可以更小。因此需要更少的推力，因此更小的发动机，导致更大的重量节省比原来的减少。这个迭代可以重复几次，虽然重量的减少给了报酬递减。

The startup process of a feedback electronic oscillator, when power to the circuit is switched on, is a technical application of the snowball effect. Electronic noise is amplified by the oscillator circuit and returned to its input filtered to contain primarily the selected (desired) frequency, gradually getting stronger in each cycle, until a steady-state oscillation is established, when the circuit parameters satisfy the Barkhausen stability criterion.

当电路接通电源时，反馈振盪器的启动过程就是滚雪球效应的技术应用。电子噪声被振荡器电路放大，回到其输入滤波，主要包含选择的(理想的)频率，在每个周期逐渐增强，直到建立一个稳态振荡，当电路参数满足巴克豪森稳定性准则。
