First,I would like to congratulate the authors,Huang LL,Xia HH and Zhu SL,on the overall great work done in preparing the review article'Ascitic Fluid Analysis in the Differential Diagnosis of Ascites:Focus on Cirrhotic Ascites'.1 However,there seems to be an error in the description of diagnosis of spontaneous bacterial peritonitis(SBP).The authors state"SBP is defined by the presence of neutrophil cells greater than or equal to 250/mL or a positive bacterial culture in the ascitic fluid without evidence of an abdominal source."The issue here is the fact that the authors make the presence of neutrophil cells greater than or equal to 250/mL for diagnoses of SBP an option(by using the conjunction term'or')and not a condition,whereas it is proven by evidence in the literature that it is a prerequisite.

Prediction of Vibration Characteristics in Beam Structure Using Sub-Scale Modeling with Experimental Validation

引用

Chinese Journal of Mechanical Engineering 2015年第5期28卷 928-934页

Geometric or sub-scale modeling techniques are used for the evaluation of large and complex dynamic structures to ensure accurate reproduction of load path and thus leading to true dynamic characteristics of such structures. The sub-scale modeling technique is very effective in the prediction of vibration characteristics of original large structure when the experimental testing is not feasible due to the absence of a large testing facility. Previous researches were more focused on free and harmonic vibration case with little or no consideration for readily encountered random vibration. A sub-scale modeling technique is proposed for estimating the vibration characteristics of any large scale structure such as Launch vehicles, Mega structures, etc., under various vibration load cases by utilizing precise scaled-down model of that dynamic structure. In order to establish an analytical correlation between the original structure and its scaled models, different scale models of isotropic cantilever beam are selected and analyzed under various vibration conditions（ i.e. free, harmonic and random） using finite element package ANSYS. The developed correlations are also validated through experimental testing The prediction made from the vibratory response of the scaled-down beam through the established sets of correlation are found similar to the response measured from the testing of original beam structure. The established correlations are equally applicable in the prediction of dynamic characteristics of any complex structure through its scaled-down models. This paper presents modified sub-scale modeling technique that enables accurate prediction of vibration characteristics of large and complex structure under not only sinusoidal but also for random vibrations.
