realistic scale
Examples
- The experimental result shows stability , liability and compatibility of the system which has reached utilitarian level
实验结果表明，该系统具有较强的稳定性、可靠性和适应性，已基本达到实用水平。 - The boundary of the seal imprints is allowed to be imperfect . experimental results confirm that the proposed scheme might be feasible for practical applications
实验结果表明，该方法具有较强的稳定性、可靠性和适应性，已基本达到实用水平。 - Centering at soft x - ray multilayer uniformity technology , we introduce general situation of multilayer , design of multilayer structure , simulation calculation , ion - beam sputtering deposition and evaluation of samples . above all , we carry out study of improving uniformity of period thickness spatial distribution , and develop correction mask for controlling period thickness . as a result , we improve uniformity from 4 . 5 % to 2 . 0 % , the error of period thickness on ( 130nm field is controlled within 0 . 18nm , and the reflectivity reach 35 % at center wavelength 17 . 1nm
特别地，我们设计并应用膜厚挡板补偿技术控制多层膜的膜厚分布，将膜厚分布非均匀性从4 . 5减小到2 ，周期厚度绝对差值控制在0 . 18nm以内，并且制备得实际多层膜样品在中心波长17 . 1nm处实测反射率达到35 ,达到实用水平。 - Different from mammals , the early embryos of fish can not be preserved for the long period at the very low temperature ( - 196 ) . therefore , three methods were usually applied to cryogenic preservation of the fine and rare species of fish : 1 ) perserving fish spermatozoon in cryogenic condition . researchers have had systematically studied on this technique for many years , and this technique has been utilized in application and made a lot of effects ; 2 ) combining with the techniques of cell engineering ( nuclear transplantation and electric fusion etc . ) , and through the process of culturing histiocyte of fish , cryopreservation and re - culture after thawing , carrying out somatic cell breeding of fish . the past studies showed that the nucleolus of somatic cells of fish have totipotency
多年来，国内外学者对各种鱼类精液的冷冻保存进行了大量的系统研究，目前这项技术已达到实用水平，并日益发挥作用；二是对鱼类培养的组织细胞冷冻保存，通过鱼类细胞的培养、超低温冻存、解冻后再培养过程，结合细胞工程技术(如核移植、电融合等)进行体细胞育种；大量的研究结果表明鱼类体细胞核具有发育的全能性，随着细胞培养技术、细胞工程技术日益发展成熟，完全具备实现鱼类物种种质长期保存的理论基础和技术条件。 - There are many face recognition techniques have been proposed and shown significant promise , and many commercial systems are available for various applications under well - controlled environment in return for the long time research effort , but robust face recognition is still difficult as many unresolved challenges , such as illumination and pose variation problems , expression problem and so on
经过几十年的发展,人脸识别研究取得很大成就,在条件可控或者理想情况下基本达到实用水平。但是目前的人脸识别技术水平在非理想情况下与实用要求有很大距离,仍有许多关键性难题需要解决,特别是光照问题、姿态问题、表情问题等。
