In this design, hardware circuit adopts liquid crystal screen and program sensor keyboard as interactive interface, 96 single-chip as chief controller, analog multi-circuit switch as transmission signal. To improve conversion accuracy, I also bond an analog to digital converter%26mdash;AD1674, so the programs mainly contain the display program design of the LCD module, the key-board control program and cyclical monitoring of various parameters and so on.

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。

The stiffness is k=EI/L where E is the modulus of elasticity, I is the crosssectional moment of inertia, and L is the length of the flexure.

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。

Electron Spectroscopy for Chemical Analyzer and Attenuated Total Reflectance – Fourier-Transform Infrared Spectrometer were employed for determining elements' functionabilities and chemical compounds. Charge Coupled Device camera and Scanning Electron Microscope were employed for macroscopic and microscopic morphologies and structural observation.
