向下定位，就是在了解全局观的基础上，通过提问去获取更多信息，以获取更细节的东西。
Chunking down is getting more detail by probing for more information about the high-level information you already have.
这些细节信息可以很好地帮助程序员来定位程序中的锁竞争，并且清楚地理解ConcurrentHashMap中哪个片段竞争最严重。
These details help programmers to locate the lock contention in the program and clearly understand which segments of ConcurrentHashMap contend most.
采用传统图像检测方法存在目标区域定位不准确、目标细节信息丢失、目标形状变形等问题，本文提出一种基于离散分数布朗随机场模型的水下图像目标检测方法。
To overcome the shortcomings of traditional methods, a method of underwater image segmentation based on the discrete fractional Brownian random field was proposed to dispose underwater images.
