邱先生所提出的计算板椿接触应力的方法,无疑地较目前常用的各种近似方法,在理论上要完善得多。惜原文中似有严重错误多处,顾提出来与邱先生及各读者共同研究。 (一)关于u_1,u_2及其他原文式(5)的第一式,其右边不应冠以负号,即应为这点可以将原文所列参考文献[1]的(13)式按y在区间(—∞,+∞)积分后乘以—1来证实(该文献中以拉应力为正,故乘—1)。因而(7)式亦应改为
The method proposed by Mr. Qiu to calculate the contact stress of the plate is undoubtedly much more perfect in theory than the various commonly used approximate methods. It seems that there are many serious mistakes in the original text, and Mr. Qi proposed to jointly study with Mr. Qiu and various readers. (1) For the first formulae of u_1,u_2 and other textual formulas (5), the right hand side should not be given a negative sign, that is to say, it should be possible to press the formula (13) of the reference [1] in the original listed text. The interval (-∞, +∞) is multiplied by -1 to verify (in the literature, tensile stress is positive, so multiply by -1). Therefore, formula (7) should also be changed to
