However, the characteristics that the multiple constraints and sequences in the auto-body assembly make the error stack-up very complex and it is difficult to search dimension-loop by utilizing the traditional dimension loop model in the 3-D variation analysis and synthesis in auto-body. Meanwhile, for the auto-body composed by great mounts of parts, the traditional Monte Carlo Simulation is time-consuming.

然而，车身装配过程中零件间的多约束特征和多装配顺序影响，使得车身装配偏差累积规律十分复杂，传统尺寸链分析方法需要建立尺寸链方程，难以适应车身三维偏差分析；同时，传统的蒙特卡洛求解方法计算效率低下，难以应用于这种复杂车身产品的公差综合。

By the theoretical analysis of the subminiature breakdown of full flow during the test of the variable pump of constant voltage,we can find the reason of the breakdown and take measure to fix it.

通过对恒压式变量泵在试验中出现全流量超小故障的理论分析，找出了故障原因，并有针对性地采取了排除措施，即(1)减小弹簧刚度，(2)弹簧材料改为高温稳定性较好的材料，并经48小时加载荷压缩处理，(3)在试验中严格控制零流量压力公差，使故障有效排除，从而从根本上解决了生产中的疑难问题。

In this paper, a theoretical analysis on the effect of the form tolerance on tensile strain measnrement was made.

就形状公差对拉伸应变测定的影响做了理论分析。
