求翻译：由表4分析可知，在载荷一定的情况下，同一模数的齿轮随着齿宽的增加，齿根两侧的应力应变在不断降低；同一齿宽的齿轮随着模数的增加，齿根两侧的应力应变同样在不断降低，这与理论计算所得结果几乎一致。是什么意思？

Analysis we can see from Table 4, the load certain circumstances, the gears with the same modulus increase in tooth width, tooth root stress and strain on both sides continues to decrease; wide gear teeth with the same modulus increases, the tooth root stress and strain on both sides of the same, wh

It can be seen from table 4, the payload analysis of conditions, the same analog bandwidth of gear with teeth, dental roots on either side of the increased stress-strain in the declining; the same width of analog gear with the increase in stress-strain of dental roots on either side has steadily dec

Analyses may know by Table 4, in load certain situation, the identical modulus gear along with the tooth width increase, the tooth root both sides stress strain is reducing unceasingly; The identical tooth width gear along with the modulus increase, the tooth root both sides stress strain unceasingl

Table 4 analyses, load under certain conditions, the same modulus gear with gear increases, falling on either side of the tooth root stress and strain; gear of the same width as the modulus increases, falling on either side of the tooth root stress and strain of the same, which is theoretical calcul
