Experiments were carried out to verify the static model. Experimental results show that the experimental curve matched well with the simulated curve, and there was certain error between them (maximal static error is 0.035 rad). The error cause was analyzed. Then the experiments were carried out to measure the dynamic performances of the side-sway joint. Experimental results show that the step response time of the joint was about 2 s steady value's tolerance zone ?

车体装焊的复杂性决定了误差产生的多因素性，车体制造过程中产生误差的工位和主要因素是不断变化的，采用相关性分析方法从众多的误差根源中准确地发现最主要的误差源；结合工程实践，论述了车体尺寸波动的相关性分析方法的原理，根据测量点的相关性分析和车体焊接工艺的层次结构，可准确地找到产生车体尺寸误差的工位；讨论了如何利用相关系数矩阵的特征值和相应的特征向量判断尺寸波动的模式，指出测量数据的波动主要按最大特征值所对应的特征向量方式波动，引起这种波动的原因是车体误差产生的主要原因，应重点采取措施加以控制；提出了应用计算机进行相关性分析的解决方案。

Firstly, we test that the error data are not normal distribution, and even the expectation is not zero. Then we analyze the possible type distribution of these error data. Finally, we use the stepwise method to fit the error data and obtain a function for some parameters of the SAIL model. As prior knowledge, the fitting function will be used to inverse these parameters ofthe SAIL model soon.

首先检验了误差数据不服从正态分布，甚至均值不为零；然后对误差数据可能服从的分布类型给予了解析，得到了指数分布和混合正态分布两种不同类型的可能分布；最后拟合了误差关于SAIL模型部分参数的函数表达式，以作为先验知识应用于反演之中。

All teachings in the great-vehicle Buddhism and its sutras regard the personal realization of Tathagatagarbha as the kernel; the personal realization of the two-vehicle Buddhism, according to the historic facts in The Four Agama Sutras, has the central thought of believing in the permanent existence of Tathagatagarbha so that the state of the remainderless nirvana becomes real, permanent and unchangeable, and does not fall into the nihilistic state. It is not just us who claim Tathagatagarbha as the kernel of Buddhism; it has been so since the very beginning when Buddha established Buddhism.

因此，大乘佛教及经典中的种种所说，都是以如来藏的实证为核心；二乘佛教的实证，依四阿含所显示的史实，则是以相信有如来藏常住不灭，使无余涅槃成为真实、常住不变，而不落入断灭境界，作为中心思想；并不是只有我们有此主张，而是佛教从释迦牟尼佛创教以来就一直都是以如来藏为核心，初转法轮时就已经如是，故在《阿含经》中仍然处处记载著这样的实例，平实已在《阿含正义》共七辑书中明确的举证《阿含经》中是如何一再开示这个正理了；此外，不仅止北传的大乘佛教与四大部阿含如此记载，南传的小乘佛教经典也是如此记载，才会有爱阿赖耶、乐阿赖耶、欣阿赖耶、喜阿赖耶、穷生死蕴等记载。
