needle-shaped
3.shrub with pungent rigid needle-shaped leaves and white flowers; eastern Australia.
4.A white mineral, NaCaB5O9?H2O, that forms rounded masses of very fine needle-shaped crystals.
5.Destruction of living tissue, especially of hair roots, by means of an electric current applied with a needle-shaped electrode.
6.any shrub or small tree of the genus Tamarix having small scalelike or needle-shaped leaves and feathery racemes of small white or pinkish flowers; of mostly coastal areas with saline soil.
7.The microstructure,microstructural parameter value,tensile properties and tensile fracture surface of the alloy were observed and analyzed. The results shown the needle-shaped Mg2Si particles with length of about 2μm and width of 100 nm or several nanometers,and elliptical-shaped Al8Si6Mg3Fe intermetallic particles were observed in the cast A356-T6 aluminum alloy.
8.Nanometer titania needle-shaped agglomeration was directly prepared by aging TiOCl2 aqueous solution from room temperature to 60°C. The effect of reaction temperature and stirring on TiO2 crystalline size and morphology were discussed. The results show the morphology of product is pseudo-sphere in the stirring condition.
9.Any of various evergreen trees of the genus Pinus, having fascicles of needle-shaped leaves and producing woody, seed-bearing cones. These trees are widely cultivated for ornament and shade and for their timber and resinous sap, which yields turpentine and pine tar.
10.1. The microstructure of 35CrMnSi steel EBW joints on two kinds of thickness were studied, the results show that the microstructure of the EBW welds is coarse needle martensite and a small amount of residual austenite; the main structures of heat affected zones are lath-shaped martensite and a small amount of residual autenite; the microstructures of base metal are ferrite and pearlite.
