Do not include internal forces, for example the car acting on itself.

不要包括内力，例如汽车作于其自身的力。

I don't have to worry about any internal forces, now these tensions become internal forces.

我不任何内力，现在这些紧张变成了内力。

Underwater pees are also lengthier because the external water pressure counteracts the internal forces resulting from elevation difference.

水下小便也更长，因为外部水压抵消了海拔差异产生的内力。

And so before we get to that we really have to understand the difference between intermolecular and intramolecular forces.

因此，在了解这一点之前，我们必须真正了解子间力和子内力之间的区别。

And the shape of the spring causes internal forces that try to return the spring to its original shape.

弹簧的形状会产生内力，试图将弹簧恢复到原来的形状。

The results showed that the Euler-Bernoulli model underestimates deformation but overestimates internal forces of tunnels.

结果表明，Euler-Bernoulli 模型低估了隧道的变形，但高估了隧道的内力。

Elastic objects are made of materials and designed, so they have internal or inside forces that try to return them to their original shape.

弹性物体由材料制成并经过设计，因此它们具有试图使其恢复到原始形状的内力或内部力。

In contrast, the proposed solution is more reasonable and accurate, by taking complex interactions between internal forces and stiffness reduction at circumferential joints into account.

相比之下，所提出的解决方案更加合理和准确，因为它考虑了内力和圆周节点刚度折减之间的复杂相互作。

It is because that the Euler-Bernoulli beam overestimates the internal forces within the tunnel, while the Timoshenko beam overestimates the bending stiffness of joints between rings.

这是因为 Euler-Bernoulli 梁高估了隧道内的内力，而 Timoshenko 梁高估了环之间接头的弯曲刚度。

4,17–20 The LECM fails to capture the abrupt deformation or changes of internal forces at tunnel joints, leading to inaccurate results when analyzing the soil-tunnel interaction.

4,17–20 LECM 无法捕捉到隧道接缝处的突然变形或内力变化，导致在析土-隧道相互作时结果不准确。

Through indoor model experiments, Atkinson and Potts studied the stability of tunnels in cohesionless soil and analyzed the internal force characteristics of tunnel lining structures under uniform surcharge loading.

通过室内模型实验，Atkinson 和 Potts 研究了隧道在无粘性土中的稳定性，并析了均匀附加载荷下隧道衬砌结构的内力特性。

In Japanese games, the gun isn't so much a gun as an extension of the self, the gun is a part of the person, the suit or the vehicle, and as a representation of internal force rather than a mere firearm.

在日本的游戏中，枪与其说是枪，不如说是自我的延伸，枪是人、衣服或车辆的一部，是内力的代表，而不仅仅是枪支。
