摘要
用分析方法证明了曲面胀出的公式 dA/dV=1/R_1+1/R_2。在数学理论上分析了该公式在金属学中晶界增长问题上应用的条件及范围。
The formula dA/dV=1/R_1+1/R_2 of curved surface expanding has been demonstrated in the
method of analysis,and the using condition and scope of the formula of the limit to the crystal expansion
in metallography has been analyzed in mathematical theory.
