研究星团的天文学家已经注意到质量一定的行星(通过追踪表面阴暗冷却斑点来测量)，其旋转速度随着其星龄呈现可预测性的变化。
Astronomers who study star clusters have noticed that the speed at which a star of a given mass spins (measured by tracking cool, dark spots on the surface) also seems to vary predictably with age.
如何相对于同步提供可伸缩性优势，以及构造通过伪随机数生成器模拟旋转骰子的简单、高竞争示例基准。
Class offered a scalability benefit over synchronization, and constructed a simple, high-contention example benchmark that simulated rolling dice with a pseudorandom number generator.
实验数据表明，该算法可抗任意角度旋转、匹配速度较快、正确率较高，而且对噪声小的尺度变化具有良好的鲁棒性。
The experimental, results show that the algorithm can against arbitrary rotation with a rather high speed and a rather high matching rate, and it is robust to scale transform with low noise.
