problematic 成问题的
e.g. Microseismic denoising is mostly performed using a simple bandpass filter, which can be problematic when signal and noise share the same frequency band.
Contrary to 相反的
e.g. Contrary to the fixed-basis transforms, the proposed method belongs to the adaptive-basis transforms.
state-of-the-art 当前最先进的
e.g. Most state-of-the-art seismic denoising methods are multi-channel techniques and are only applicable to microseismic data with a dense spatial sampling.
