【摘要】：將自制四端低值電阻的標(biāo)定用于開放實(shí)驗(yàn)中,不僅可提高學(xué)生綜合使用實(shí)驗(yàn)儀器及動(dòng)手的能力,還可加深學(xué)生對測量不確定度理論知識的理解。實(shí)驗(yàn)中讓學(xué)生自主選擇制作材料、實(shí)驗(yàn)器材、設(shè)計(jì)實(shí)驗(yàn)電路、確定實(shí)驗(yàn)方法。用非等精度測量法測量自制四端低值電阻。應(yīng)用測量不確定度理論,采用加權(quán)平均法,給出測量結(jié)果的不確定度。開放模式的實(shí)驗(yàn)教學(xué)設(shè)備利用率高、實(shí)驗(yàn)效果好,有利于培養(yǎng)學(xué)生的實(shí)踐和創(chuàng)新能力。
[Abstract]:The calibration of self-made four-terminal low-value resistor in open experiment can not only improve the students' comprehensive ability to use experimental instruments and practice, but also deepen the students' understanding of the theoretical knowledge of measurement uncertainty. In the experiment, students are allowed to choose the material, equipment, circuit and method. The self-made low-value resistance of four ends was measured by non-equal precision measurement method. The uncertainty of measurement results is given by using the theory of uncertainty and the weighted average method. The open mode experiment teaching equipment utilization rate is high, the experiment effect is good, is advantageous to train the student's practice and the innovation ability.
