主　　题：terahertz generation water lines 

摘      要：To make further understanding of terahertz(THz)wave generation from liquid water,we study THz wave emission from water lines of different *** water line with a smaller diameter generates a stronger THz electric field for the diameters from 0.2 mm to 0.5 *** THz electric field strength and polarity change with the relative position between the incident laser and water ***,the THz energy has an optimal radiation angle of about 60°.A two-dimensional dipole array model is introduced to illustrate the *** observations contribute to optimizing the scheme of the liquid THz source.
