有效限制

This method is much more efficient than the bubble sort, though it has more constraints.

这种方法更有效比冒泡排序，但有更多的限制。

The external fixator was a good, economical, effective and simple method in the treatment of femoral neck fracture. The three pins used in fixation of femoral neck fracture are important. The placement of the pins should be in accordance with the compressive trabeculae and clingy to the femoral calcar.

3动力髋螺钉虽然在固定强度上优于其它各组，但却由于手术创伤大、对股骨头残存血供破坏较大等缺点而限制了其应用；自行设计的外固定支架为一种简单、有效、实用、经济的固定方法，有一定的推广价值；穿针方向应循压力骨小梁方向尽量贴近股骨距低角度倒三角形钻入才符合生物力学原理。

In modern physics research, the calculus of variations has a broad application of law. As a solid mechanics, structural mechanics and computational mechanics of the theoretical foundation, it has important value in theory and practice on the mechanics; Variation method ruled out the perturbation of the restrictions can be widely used in many state-level and the state function in the calculation in the optical; Calculus of variations can be calculated with the parameters, we can guarantee the reliability of the results, can effectively reduce the workload of calculation, It can be said that the applications of calculus of variations are very broad.

在现代的物理学研究中，变分法有着广泛的应用：在力学上，变分法作为固体力学、结构力学及计算力学的理论基础，在理论上和实践上都有重要的价值；在光学上，变分法排除了微扰法的限制，可以广泛应用于诸多定态能级和态函数的计算中；在量子力学的应用中，具有可算出系统的参数，既可以保证计算结果的可靠性，又能有效地减少计算的工作量等的优点，可以说变分法的应用领域十分广阔。

Although highly-effective at smashing through hulls and at repelling boarders, the main drawback of the carronade was still the short range of the weapon (captains were unable to use it properly until their ships had acquired a target less than half a kilometre away).

尽管在清理甲板和在敌舰上打洞有非凡的能力，卡隆炮还是因为短射程而受到限制（船长只能在500米之内才能有效的使用这种武器）。

Section 172 of the Clean Air Act , as amended in 1977, authorized postponement of the date

正如1977年修正的《洁净空气法案》中的第172条那样，如果控制的方法是"有效且实际"的话，批准延长时间到1982年，或者把对氧化剂和一氧化碳的限制延长到1987年。

Just under this condition, the international regime could effectively limit the interest conflicts and strengthen the common interest among nations, and finally achieve the best collective fruit. In the late 20th, the world situation has changed a lot. The general tendency of maintaining peace and promoting development has come into being.

正是在这种情况下，国际机制可以有效地限制国家之间的利益冲突，突出国家之间的利益趋同，取得集体最佳结果。20世纪后期，世界形势开始发生重大变化，形成了有利于维护和平、促进发展的总趋势。

Collegiality, however, did not effectively limit the supremacy of the pope.

合议，然而，没有有效地限制了至高无上的教宗。

As to the remaining parameters, two methods are developed: first, accepting that the projection function complies with a circular function within at least a part of a given field of view, constrained by the obtained object-to-image radial mapping and a constant focal length, the best-fitting point of the optical origin is tested along the optical axis; secondly, referring to the postulation of the exclusively bilateral mapping between an imaged point and its scenic sight ray, a measuring technique is developed to survey the world coordinates which will fabricate a projecting path to the imaged points located on the imageable region of the image plane in order to directly model the projection geometries involved.

而针对其余参数本文提出两种解题方法：其一是根据『在「部分视野角范围」内，鱼眼相机的投射模型符合一典型的「圆形函数」』以标靶实体与其影像尺寸为限制条件，测试光学轴上的最佳视觉参考点、鉴定最适当的投射模型、焦距、及有效的视野角度范围。其二是根据『一视野线排他性地与对应「呈影点」一一映射』参考一呈影点来搜寻空间中对应视野线的绝对座标后，据以演绎相机内部影像形成的模型。

Indicate the existence of the imbalance in the supply structure, low consumption-oriented sectors of the housing supply too small, if not to strengthen the guidance and control, there will be a structural phenomenon of subversion and affect the normal development of the real estate market.

难以形成这样一个管理系统，协调的运作和有效的互动，长期的存在不可避免地控制，管理司，并明确责任，太多的联系，提高效率不是这种现象，在一定程度上限制了快速发展房地产市场。

This paper is trying to do some counterproposal studies pointing to main outstanding issues of transpacific market, but due to limited information, it is not able to solve all current problems and needs more theoretical analysis to this particular market in the future.

本文试图对该航线的主要问题提出可行的对策和方案，但由于在信息搜集等方面的限制，本文不可能对所有问题得出有效的结论，还有待进一步的分析和研究。
