the gravity center model

基本解释

The blog idea served as the center of gravity for the new model, and other audience channels were connected to create an experimental new "ecosystem."
创建博客的想法成为了这一新模式的重心，此外，我们还将其他受众渠道连接起来，建立了一个实验性的新"生态系统"。
The novel toy is simple durable, having easy installation. The wing position and a model gravity center can be adjusted to obtain more perfect flying state.
本新型玩具简单耐用，易于安装，并且可调节机翼位置及模型重心，以获得更完美的飞行状态。
