Keeping the user either involved in the development or-at the very least-using the earliest prototypes and alpha releases to get their feedback will hopefully keep the project on the right track.
使用户参与到开发当中，或者至少使用最早的原型和alpha版本获得用户的反馈，这样有望使项目步入正确的轨道。
A single alpha particle generates a track of from 30,000 to 70,000 positive and negative ions per cm, which may be polarized and moved about by ambient electric fields.
一个单个的阿尔法粒子能够产生每厘米30000到70000个正、负离子的踪迹，这些粒子可能受到周围电场的作用而极化或运动。
In the paper a personnel neutron dosimeter based on a CR-39 plastic track detector registering heavy recoils and alpha particles is described.
