It can work well when fluid ' s flowrate is above 0 . 1 - 0 . 2m / s , but when it works below the range , great error will be occurred . so the application of electromagnetic flowmeter has been narrowed 2m / s以上的流速时能良好地工作，但在这一下限之下时，因为误差太大而无法使用，很大程度上限制了电磁流量计的应用。
However , the existing waterfront north of hong kong island has been occupied by developments and waterfront facilities that restrict , if not totally deprive , the public of access . providing convenient harbour access 不过，港岛北面海旁多年来一直被各式各样的发展和设施所占用，很大程度上限制了市民前往和享用海旁其中有很多部分的海旁，市民已无法抵达。
Yet stochastic reliability method is strongly depends upon the available information , but in engineering , often only limited information is available , which greatly restricts the applications of stochastic reliability method in engineering 但随机可靠性方法对已知数据的较强依赖性，和实际工程中可得数据的有限性，在一定程度上限制了随机可靠性方法在实际工程中的应用。
However , the magnetic field produced by common magnet can keep the gradient unchanged only in a small area . so , if we use common magnet and hore component to measure the movement of the object , we can only measure in a small area 然而，一般磁场只可能在极小的范围内保持均匀梯度，若要求在大范围内保持均匀梯度，其磁场结构复杂、体积庞大，在很大程度上限制了霍尔元件测量位移的应用。
In the present rapid prototyping technologies , however , the stl file based data processing method and the staircase effect , which is inevitable during rapid prototyping process , restricts the further improvement of the part precision 然而在快速成形技术中，目前普遍采用基于stl文件的数据处理方式，再加上在成形过程中难以克服的阶梯效应，这就在一定程度上限制了制件精度的进一步提高。
These guidelines are not mandatory , but many countries in asia do use these guidelines , along with the scientific data determined by the national regulatory agencies to establish limits on use and also acceptable residue levels at point of sale 这些指南并不是强制的，但是许多的亚洲国家确实在使用这些指南，还有与由全国管理机构确定建立在用途上限制，和可接受的卖点时残余水平的科学数据。

It is important to seek effective reduction algorithm in rough sets because of less efficiency of the complete algorithm of attributes reduction based on the discernibility function and incomplete of heuristic reduction algorithm 现有的基于区分矩阵和区分函数的属性约简完备算法的低效性和启发式算法的不完备性在一定程度上限制了粗糙集理论的广泛应用,因此寻求高效的粗糙集算法具有重要的意义。
From a revenue point of view the policy restricting the use of opium in formosa is no doubt unfavorable , for it means the state a serious loss of income on the one side , and increased expenses for administration and the surveillance of opium smokers on the other side 从收入的观点上看，这个在福尔摩沙岛上限制鸦片的政策无疑的是不受欢迎的，因为它一方面对国家是收入上的损失，另一方面在对吸食监管上增加了支出。
With trademark protection focusing on the deceitful sale or the palming off of goods , courts were forced into the laborious practice of finding injury in the form of consumer confusion when there was no diversion of customers or sales but the plaintiff had suffered harm 到目前为止,美国法院还是通过运用较为零散的个案处理方式来限制能够获得驰名商标反淡化保护的驰名商标的数量,并没有在本质上限制驰名商标保护的形式。
