为了切割和连接极细的金属丝，考虑了丝中的焦耳加热问题。通过直流电源使直径约800 nm的细Pt线的一部分的中间局部熔化，并且通过施加力以剪切线的熔化部分而在预定点处切断线。此外，将恒定电流施加到其中两个Pt线的自由端接触的系统，并且将线连接在一起。提出了一个参数，它管辖的熔化现象在接触点的非常细的电线，。经验证，连接细导线所需的条件能够由取决于所施加的电流、导线的长度和横截面积的参数以及用于校准热条件的几何量的函数来确定。(C)2009年美国物理学会。[DOI：10.1063/1.3058643]
For cutting and joining extremely thin metallic wires, the issue of Joule heating in the wires is considered. The middle of a section of a thin Pt wire with a diameter of about 800 nm was melted locally by a direct current supply, and the wire was cut at a predetermined point by applying a force to shear the molten part of the wire. Furthermore, a constant current was applied to a system in which the free ends of two Pt wires were contacted, and the wires were joined together. A parameter, which governs the melting phenomenon at the point of contact of very thin wires, is proposed. It was verified that the conditions required for joining thin wires were able to be determined by the parameter that depends on the applied current, the length and cross sectional area of the wires, and a function of the geometrical quantities for calibrating the thermal conditions.
