The present invention relates to a method for testing of a plate-shaped body (1) consists of a fiber composite plastic by means of a partial comprises in a front face (2) of the test specimen (1), in which the test piece cannot cause in its test position is mounted at the edge, ...
The characteristic point of a one-parameter family of surfaces corresponding to the valueu0of the parameter is the limit of the point of intersection of the surfaces corresponding to the valuesu0,u1, andu2of the parameter asu1andu2approachu0independently. ...
1) Characteristic mixed length 特征混合长度2) mixed feature 混合特征 1. Face recognition based on mixed feature of ICA in PCA residual face space; 基于PCA余像空间的ICA混合特征人脸识别方法 2. Aiming at the characteristic in feature extraction of cold steel strip surface defect images,a mixed ...
For flow in a pipe, the inlet flow velocity is taken to be the characteristic velocity and the characteristic length is the diameter of the pipe. Another example is flow over a blunt body (for example, a truck moving on a highway) where the front-view height of the truck is usually ...
the structural length of the stop valve is longer than that of the gate valve, and the fluid resistance is large. during long-term operation, the sealing reliability is not strong. 进口自密封截止阀principle: when in use, the connecting rod is driven to rotate by rotating the hand wheel, ...
aThere are a lot of differences among the LP conception,importance,range and characteristic features within Europe and also among the names of LP..or example there is a.reight Village in Great Britain,a Plate. 有在LP构想,重要性,范围中的很多区别,并且性能特征在欧洲之内并且在那里LP。.or例子之...
development (Tang et al.2008). Through establishing knock-in mice expressing full length PDGFRβ or PDGFRβ with mutations to allow its constitutive activation, a comparable postnatal adipose tissue generation was seen, showing that pericytes are not the only origin of adipocytes. Although elevated ...
We first describe the importance of reasonable design of vane plate by the analysis of static properties and inner force computation on the steady flow variable vane pump,and then design a kind of valve plate. 通过时稳流式变量叶片泵的静态特性分析,调节内力计算,论述了配油盘合理设计的重要性,设...
Strain Distribution Analysis during Tensile Deformation of Silicon Nanowire with 4D-STEM Deformation in materials is a multiscale problem, which is usually identified by three characteristic length scales: atomic scale, micrometer scale, and macroscale [1]. The atomistic deformation, including lattice di...
