不固定的

Picker-wheel support structure was used in strip label papers of tobacco industry, but it had appeared some problems : picker-wheel vibrates easily, label paper was picked insecurely, and double-shafts generated deformation and linear bearings wear easily. The ultimate cause was founded by analyzing linear bearings stress from statics and dynam-c- teplaced by two-side support with one fixed end and one free end.

针对FOCKE350S条盒商标纸拾取轮总成支撑结构拾取轮易振动、商标纸拾取不可靠、双轴易弯曲变形、直线轴承磨损快的情况，从静力学和动力学的角度分析了直线轴承磨损快的根本原因；并将原来双轴单侧支撑结构改为双轴双侧支撑，采用一端固定，一端游动的支撑方式。

As shown in the cycle-stiffness curve, the stiffness was significantly higher for Krag and caudad method than for Magerl method (P.01). Conclusion In osteoporotic lumbar vertebrae, the placement of pedicle screws should not paralled superior endplate and polyaxial pedicle screws should be chosen.

对于骨质疏松患者的腰椎后路椎弓根螺钉内固定手术，常用的螺钉平行上终板的技术不能提供最好的生物力学稳定性。

In particular, because of their low mass and their tendency to interact with one another over great distances, they cannot be "pinned down" to any one location.

特别地，由于它们的质量很小而且有与远距离的离子进行相互作用的倾向，它们不会被固定在任何一个位置。

In the seismic analysis of hydraulic engineering before, the traditional model of fixed boundary with massless foundation were often adapted, and the radiation damping of foundation and the inhomogeneity input of wave-motion could not be took into account.

以往大多数水利工程的抗震分析中，多采用传统的固定边界无质量地基模型，该模型未能考虑地基辐射阻尼的影响和地震波动的不均匀输入等问题。

In this type of exercise your foot is planted on the floor and it is not free to move about.

这阶段的练习中，你的脚在地板上被固定而不是自由的移动。

On the one hand, because of the short action time, it is impossible to get enough time to circumvolve instruments or to circumvolve the physical fields being measured so as to scan in all directions, so the physical fields can only be measured through several instruments; on the other hand, because the physical fields are partly screened or the operator domain is too limited, the measurement directions are limited, too.

一方面，因为作用时间短，不可能有充足的时间使仪器旋转或使被测物场旋转来全方位扫描，只能固定几个方位的探头同时进行测量；另一方面，由于物体被部分遮挡或作用域小，使观测方位受到限制，也只能在测量中用少量的探头。

The artistic approach of Liu Yan's works lie between abstraction and expressionism. All of her paintings should be viewed as a whole, in which the composition are showed in alternation between imagery and abstractness, and never regularized in any pattern pictorially.

刘艳的画介于抽象与表现之间，她的作品应该是一个整体，表现的意象与抽象的构成总是相互穿插，不是固定在哪一个画面上。

A plane curve formed by the locusof points equidistant from a fixed line and a fixed point not on the line.

抛物线到一固定直线和不在直线上某一固定点等距的点的轨迹所形成的平面曲线。

A posteriorly wired contoured rod is less likely to provide a good fusion environment because of less stabilizing potential and a greater likelihood of loosening with fatigue.

而后路钢丝轮廓棒固定则不太可能提供一个很好的融合环境，因为较低的稳定潜力和更大的在疲惫负荷后的松动可能性。
