1. But during the rotation, accelerometers bias error could also be modulated as an installation error, so it needs to build a model of accelerometer rotation error for compensating. 针对平台惯导台体绕方位轴旋转时加速度计误差补偿的实际需要，建立加速度计由初始安装误差角引起的旋转误差模型。
2. Then system error contains angle measurement error, structure error, assembly error, bearing play etc. is discussed, and the compensation equations are given. 然后研究了综合转角测量误差、结构误差、安装误差、轴承窜动等在内的系统误差，通过计算给出了补偿公式。
3. Big and small of residual error and rule of sign change was observed with inspection method of residual error, and if it had system error or rough error and so on was identified. 采用残余误差观察法观察残差图中各个残余误差大小和符号变化规律，可直接判断有无系统误差。
4. Detailed introduction is made into the soleplate installation scheme, the installation specifications and the installation procedures, etc. 本文主要就造纸机的基础板安装方案、基础板安装规范和安装实施等过程作详细介绍。
5. It introduces the installation method of this welder in detail and the difference between semi-automatic welder about installation, including installation of welding jig and welding carriage. 详细介绍了自动焊机的安装方法，区别于半自动焊机安装的地方，包括焊接夹具的安装以及焊接小车的安装。
