Using nickel added X70 steel as a sample material, we demonstrate that electron work function (EWF), which largely reflects the electron behavior of materials, could be used as a guide parameter for material modification or design. Adding Ni having a higher electron work function to X70 steel brings more "free" electrons to the steel, leading to increased(More)
In order to adapt to high accuracy test requirement of dynamic balancing of Electric spindle. According to the harmonic wavelet phase locked, narrow-band analysis and the clear expression in time-domain, the method and algorithm of adaptive filtering based on harmonic wavelet was given. This method in accordance with the signal correlation, the dynamic(More)
The RNA guided CRISPR/Cas9 nucleases have been proven to be effective for gene disruption in various animal models including Xenopus tropicalis. The neural crest (NC) is a transient cell population during embryonic development and contributes to a large variety of tissues. Currently, loss-of-function studies on NC development in X. tropicalis are largely(More)
