使弯曲

That will force back to be arch-shape, then cause slenderest ligament and muscular of low back to strain, and expand abdomen muscle. Body will benefit few.

这种动作，将迫使背部弯曲成拱形，而使背部下方最狭部分的韧带和肌肉紧张，并扩张腹部肌肉，对于身体弊多益少。

Only go as low as you feel pain-free and stable.

During the pipe pushing construction of the parallel steel water pipeline of Beidu-Yanger pipeline project in Ningbo, the pushing force in main pushing power station appeared unusual increasing and the construction had to be interrupted. Through the analytical comparison between theoretical and practical pushing curves as well as the analytical comparison between the tool pipe track and the form map of pipeline resting in soil, it was found that the excessive pushing force in main pushing power station was caused by excessive deviation adjustment angle which enabled the pipeline to over bend in a short distance.

在宁波市北渡－雅戈尔原水D1800mm钢管复线工程顶管施工中，出现主顶动力站顶力异常增大的现象，影响继续顶进施工，文章针对这一情况进行分析研究，通过理论顶力曲线与实际顶力曲线以及工具管所经轨迹与管道在土层中静止时的形态图的分析比较，得出主顶动力站顶力过大是因为在纠偏过程中纠偏角度过大，使管道在短距离内过度弯曲引起的。

In contrast, the new technology used in the new Zeta OEM sensors eliminates any pivots, pullers

相比之下，新技术采用了新的ZetaOEM传感器，从而减少任何枢轴、张力辊、弯曲或轴承的使

Test tasks: to check whether the loose connector; hand plate coupling the rotor to move a few laps to see whether rotation and flexible unit, whether there is uneven sound and light and heavy feeling, to determine whether pump or foreign body axis is curved seals, such as the installation is correct; inspection seal on the 20th cavity clean lubricants are added 1 / 2 cavity space; pump unit surface is clean; unit no-load test shift.

For canvases over 40", it is best to brace the back or corners, if not using heavy duty stretchers. A major brand for stretcher bars is Fredrix, and these are sold in art stores and some office supply stores. If you are handy with saws, you can make your own stretchers with wood from the lumber yard, a piece of curved molding, and a mitre saw. Me, I'd rather spend my time painting, so I buy pre-made stretchers. You also will need "keys for the stretchers, small wooden angled chips, which are used to make the stretched canvas more snug in the corners. These are free, and are usually found near the stretcher bars, in a box. You need 8 of them; just grab a small handful when you buy your stretcher bars.
