replace, substitute这一类表示替换的词， for 后面表示的是‘被替换者’边际替代率是指增加一个数量的某产品时必须放弃的另一种产品的数量，这里的边际替代率是2，应该是用1个a换2个b
边际替代率，A对B的边际替代率是2，说明一个A可以替代两个B，自然是为了一个A可以放弃两个B。The rate or ratio at which goods X and Y are to be exchanged is known as the marginal rate of substitution (MRS). In the words of Hicks:“The marginal rate of substitution of X for ...
The lattice thermal conductivity of the Bi analog is, however, higher than the Sb analog, and this correlates with the decrease in the degree of mass fluctuation between the nanostructures and the matrix (for the Bi analog). As a result the dimensionless figure of merit ZT of Ag1-xPb18...
