4-(4-chlorobenzylideneamino)-3-(1H-1,2,4-triazol-1-ylmethyl)-1H-1,2,4-triazole-5(4H)-thione

In the title compound, C12H10ClN7S, the dihedral angles made by the plane of the thione-substituted triazole ring with the planes of the other triazole ring and the benzene ring are 73.57 (3) and 46.65 (2)degrees, respectively. Inter-and intramolcular hydrogen bonds and pi-pi stacking interactions stabilize the structure.

5-[(1H-1,2,4-yriazol-1-yl)methyl]-4-(4-fluorobenzylideneamino)-2H-1,2,4-triazole-3(4H)-thione

In the title compound, C12H10FN7S, the dihedral angles made by the plane of the thione-substituted triazole ring with the planes of the other triazole ring and the benzene ring are 71.94 (3) and 40.10 (2)degrees, respectively. Inter- and intramolecular hydrogen-bond and pi-pi stacking interactions stabilize the structure.

智能化工程机械发展战略研究

The intelligent level of construction machinery abroad is described in the article. In association with automation level of domestic construction machinery, developing targets are pointed out. Some plans and schemes in national technical 863 projects are introduced, which may be of reference to domestic enterprises when making developing schedule for organization.
