同时利用地下河发育密度和多年平均径流模数，结合各地区多年平均降水量，对重庆市地下河水资源的分布规律进行了分析，得出地下河发育密集地区并不一定就是水资源量大的地区；降水量高的地区也不一定是地下河水资源量大的地区，二者在重庆市存在较大差异。

Figure 11.4 lists the sizes of 0.5 LSB at various resolutions (the values are given for 10 V fullscale since this is a classical converter range and where LSBs are given a mV value in this section of the seminar a 10 V FS is assumed unless explicitly stated otherwise - scaling to other values of FS is a trivial operation).

图11.4给出了不同分辨率条件下0.5LSB对应的变化量。（鉴于目前模数转换器典型的满量程范围是10V，所以表格中的数据都是按照满量程10V计算。本文中，如果没有特别说明，当1LSB为mV量级时，其满量程范围都是10V，满量程不等于10V的情况可以参照本例推算。
