During the generation of markup or during the execution of an action , it is often necessary to access a slow backend or perform some type of time consuming calculation 在标记生成期间或操作执行期间，经常有必要访问慢速后端或执行一些较为费时的计算。
Time could be managed more efficiently and this would give schools more time to complete their own tasks instead of spending it in meetings and negotiations 必须要能更有效地管理时间，使学校有更多的时间完成他们的工作，而不是召开一些旷日费时的会议。
This can be implemented as a hardware facility or uart relieving processor ( and applications programmer ) of this low - level , time - consuming , detail 这种工作可以使用硬件或者uart来实现，可以将处理器或者应用程序从这种底层的、费时的和琐碎的工作解脱出来。
The best they can do is to find a manufacturing process that works ? as proved through a series of expensive , time - consuming clinical trials ? and then stick with it 他们能做的就是找到一种有效的制程，然后就再也不改了这靠的是一连串昂贵又费时的临床实验。
Whitman says it takes time to analyze the seismic data , conduct atmospheric tests and do other work he cannot discuss to determine what caused the explosion 怀特曼说依靠分析地震数据，进行大气监测和其他不能在此讨论的工作来来检测是什么引发了这次爆炸是十分费时的。
Adaptive page caching and portlet caching provide powerful means for reducing the rendering time by avoiding the potentially time - consuming markup generation of portlets 自适应页面缓存和portlet缓存提供了强大的方法，用以通过避免可能很费时的portlet标记生成过程来缩短呈现时间。
You could go to each machine and manually check all of these issues , but when the machines are dispersed over a wide area , this can be a very time - consuming process 您可以走到每台机器前手工检查核对所有这些问题，但是当机器分散在一个广阔的区域内，这样做会是一个非常费时的过程。
A standard practice to minimize the impact of the model systematic error is to calculate the anomaly from " model climate " rather than from the observed climate 计算模式气候是相当费时的工作。现时天文台是以1998至2001年间rcm的输出来运算模式气候，并假设模式气候是接近常态分布。
In the research of modern genetics eugenics and clinical diagnosis , the analysis of chromosome karyotype is inconvenient and time consuming , for it is always performed manually 现代遗传学、优生学、临床检验等都需要进行染色体的核型分类,但是这项工作是繁琐、费时的、一直以来都依靠目视、手贴完成。
Generally , edges in some specified directions can be only detected by most of edges detectors , and detecting edges in many different orientations using usual convolution means is very costly computationally 通常的边缘检测器只能有效检测几个特定方向的边缘，如果需要检测图像中各个不同方向的边缘，使用通常的卷积方法在计算上是十分费时的。
