0 the part of a nut that is inside the shell and can be eaten -- （堅果可食用的）仁，核
1 the most important part of something, although it might not always be easy to find -- 核心，中心，要點
There is often a kernel of truth in what they say. 他們的話裡常包含些真理。
Then we review kernels in modern learning algorithms, but we can keep this section short because there are good books on the subject.
To detect edges, we utilize a general family of edge detectors based on concentration kernels.
Furthermore, kernels occur in all three, and this is another reason why kernels are a central tool in meshless methods.
Since we want to stay on the numerical analysis side, we only present the most important connection to approximation by kernels.
However, the higher order kernels are not necessarily small compared with the lower order kernels.
The starch granules were more angular in the dry kernels than in the imbibed kernels, in which the starch granules were rounder and more turgid.
Although the kernels were hand-harvested and handthreshed, almost 85% of the kernels had an internal crack of some sort, as judged by visual inspection.
I propose to use the numerically evaluated kernels in the general situation.
