At the same time , for the large area of the r aw material field , it was n ' t convenient to exchange information with technology section of the headquarter of ih every day 由于全部用手工来完成，计算过程费时费力，且结果不够准确及时。同时由于其原料场面积大，每天和工业港总部技术科的信息交流也不方便。
The actual design ordinarily adopts the full - size experimentation means , which has the advantages that can reflect the real resistance , but its " shortage is also obviously : complex , uneconomic and mess around 这种设计方法的优点是可以比较真实的反映结构的承载力，缺点是太麻烦，每次都要做试验，不但费时费力，而且也不经济。
Considering all operating mode is difficult this paper , based on the traditional ways , proposes a new method in choosing operating mode , aided by establishing couple degree 传统选择方法考虑运行方式较少，使得整定值过于保守；而考虑所有的运行方式则费时费力。本文在传统选择方法的基础上，提出了一种基于耦合度的运行方式选择方法。
Traditional detection methods are time - consuming and laborious with low detection sensitivity . it is the advantages of dna chips that are quick , accurate and simultaneous viruses " detection with higher sensitivity 传统免疫检测方法难以检测潜伏期以及抗原表位发生突变的患者且灵敏度较低； pcr方法每次只能检测一种病毒，费时费力。
In this paper , we choose a new model of color image to value images ’ definition ; besides , the algorithm assess image quality based on the color information . thus , the result inclines to the 实验结果表明,本算法对图像质量的评价结果符合人眼实测效果,性能优于传统的客观图像质量评价方法,同时克服了主观评价方法费时费力、不可重复的缺点。
Tip # 9 : many change control systems are difficult and time - consuming to use . stakeholders often ? go around the system ? causing substantive trouble . why not make it easy t o accommodate desirable changes 技巧9 :很多变更控制系统使用起来费时费力.项目干系人常常在这些系统之间徘徊从而导致很多问题,为什么不使它变得容易与我们所期望的变更相结合
Moreover the performances of system in varying duty are not known . the cost of experiment is too high . the main work of this paper is compiling the computer aided design and simulation software of this kind of model 机组的工艺设计繁杂，还没有适用于这种机型的设计软件，人工计算费时费力，而且整个机组在变工况下的工作特性还不了解，实验成本昂贵。
It was a long , difficult business , for the coins were of all countries and sizes - doubloons , and louis - d ors , and guineas , and pieces of eight , and i know not what besides , all shaken together at random 这是个费时费力的活儿，因为这些硬币来自各个国家，模样各异西班牙金币，还有法国金路易英国基尼以及八里亚尔的西班牙银元，还有其他我不认识的，都杂乱地混在一起。
At present , there is no effective medicaments and rapid diagnosis method available . the main prevention methods of the disease depend on classical vaccination and diagnosis that is based mainly on serological and virology methods , but they are all time consuming and laborious 目前尚无治疗该病的特效药物，主要通过传统疫苗进行预防；该病的确诊主要依赖病毒的分离鉴定和血清学方法，这些传统方法多费时费力。
Traditionally , artificial regionalization expends much manpower and money , and the proposed gis method is more easy and effective . ' in regions lack of data directly concerning distribution of debris flows , this method is suitably to evaluate debris - flow ' s activity 以往人工进行泥石流危险度区划费时费力，用gis来做区划，简便、合理和细化。在泥石流资料较缺乏的地区，用间接指标进行泥石流危险度区划，对评价泥石流活动性有重要意义。
