Research has shown that activation of the transverses abdominus also activates the pelvic floor, keeping these muscles strong and supple for the birthing process.

研究表明，活化的断面腹直肌还启动了盆底，这些肌肉保持强劲的生产过程和柔软。

For the cases of grillages with only one different transverse or with only one pair of different transverses symmetrically arranged, the solution can be simplified to one formula only.

对于仅有一根不同横梁或一对对称布置的不同横梁的板架，又可将该问题的解简化为一个单独的计算公式。
