像素阵列的扫描方式使用多采样技术可以提高传感器动态范围2~N倍，相关二次采样技术消除了像素单元之间的固定模式噪声，使用流水线式的模数转换器可以实现好的分辨率、速度和面积等的折衷。

Chapter 3: introduces the design and realization of one part of PAMS, the PCI Communication Board, together with a brief description on PCI bus design principles.

第4章，介绍了系统组成模块&基于DAC的高谱纯度低频差分信号源&的设计与实现，讨论了Σ-Δ模-数转换器的原理和特点，并对信号源的补偿方法作了介绍。

Sparse conditions, the changes of the basal internode moment only depend on the number of stem materials to be achieved; in dense-planting conditions, the changes of the basal internode breaking moment are through the changes of section modulus and bending stress two factors together to be acheieved.

稀植条件下，基节折断弯矩的变化单靠构成茎秆材料的数量来实现；密植条件下，基节折断弯矩的变化是通过断面模数和弯曲应力两因素共同实现的。

Theoretical analysis of strip mills AGC had been processed and a three-DOF mathematical model of hydraulic screw-down system had been built,which was specified cylinder displacement and inner gap and adapt to varied control way.

对板带轧机自动厚度控制模型进行了理论分析，建立了三自由度轧机负载的液压压下系统的模型，将缸位移和内辊缝相区分，使其适用于不同的控制方式，进而对厚度计式控制模型、变形的厚度计式控制模型、动态设定控制模型进行了对比研究，指出轧机模数和轧件塑性系数分别对应于自动厚度控制系统的静态指标和动态指标，为控制过程中参数的选取提供理论依据。

The distribution of the underground rivers is consistent with the occurrence of the carbonate rocks in Chongqing.

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。

The split between the two groups can hardly be papered over.
