Traditional machine translation based on RNN has two major defects: (1)it can only process word-by-word and result in slow training speed; (2)when the sentence is too long, gradient disappearance explosion reduce accuracy of translation. To solve this problem, paper designs a Transformer implemented by PyTorch. Compared with traditional translation, uses attention mechanism to redesign defects effectively solves problems efficiency forgetting. The French-English designed achieves rate 80%...
Elemental phosphorus nanostructures are notorious for a large number of allotropes, which limits their usefulness as semiconductors. To limit this structural diversity, we synthesize selectively quasi-1D inside carbon nanotubes (CNTs) that act both stable templates and nanoreactors. Whereas zigzag nanoribbons form preferably in CNTs with an inner diameter exceeding 1.4 nm, previously unknown square columnar structure is observed to narrower nanotubes.
