aIn Section 7.2 we presented a simple application of the cross-correlation function formulation of the S-matrix to one-dimensional barrier reflection and transmission cmfficients (Figure 7.6). Equation 7.45, which was used there, is the one-dimensional version of Eq. 18.29. In this section, we...
11、In this equation, Y represents the average cost of different quantities of units.在这个方程序中,Y代表不同数量单位(x个)的平均成本。 12、The average amount of water reported, if we were to extract it, is about a quart of water per ton.如果要提取水,每吨(表层土壤)含水量大约为一夸脱。
