求翻译：为了施加不同的材料模型，对弹簧的残余应力进行了检测，检测位置如图1所示。表1是某试件残余应力的检测结果，根据表1的残余应力检测结果，设计不同小的区域的材料模型参数。由于喷丸与强压处理，材料在各个区域的残余应力的形式以及大小有较大的差别。根据表1的检测结果可知，残余应力基本上都是压应力。考虑弹簧变形过程中，材料若为单向应力，则总应力为变形产生的应力与残余应力的合成，其应力与应变关系如式（3）所示。是什么意思？

To impose different material models, the residual stress of the spring testing, to detect the location shown in Figure 1. Table 1 is a specimen test results of the residual stress and residual stress test results in Table 1, the design of different small area of ​​the material model parameters. Due

In order to exert different kinds of material models in the spring, the residual stress tests that position as shown in Figure 1. Table 1 is a test specimen of residual stress test results, according to Table 1 of the residual stress test results, the design of different small areas of the material

In order to exert the different material model, has carried on the examination to the spring residual stress, examines position as shown in Figure 1.Table 1 is some test sample residual stress examination result, according to Table 1 residual stress examination result, design different small region

In order to impose a different material models, on residual stress measurement of spring, testing location as shown in Figure 1. Table 1 is a specimen of residual stress test results, according to table 1 of residual stress measurement results, design materials models parameters in different regions
