| 2 | 评估内燃机隔振系统功率流传递的一种新模型(英文)显示文摘为准确评估弹性复杂隔振基础条件下振动内燃机的功率流传递水平,采用Mindlin板替代传统的Kirchihoff薄板,建立了一种涵盖多种隔振基础形式的普适模型。运用子结构技术和变分理论,推导了隔振系统的控制方程以及传递到较厚甚至不同配置方式的各向异性复杂梁式基础的功率流。与基于各向同性薄板基础的传统模型相比较,研究了普适隔振系统功率流的传递特性。仿真研究表明,所提模型是有效的,可得到比传统模型更加准确的结果。 | 牛军川 葛培琪 林志华 梁以德 宋孔杰 LIM C W LEUNG A Y T | 2009 | 内燃机学报2009，27，1： | 3 |
| 3 | Prevalence of advanced liver fibrosis and steatosis in type-2 diabetics with normal transaminases:A prospective cohort study显示文摘BACKGROUND Nonalcoholic fatty liver disease(NAFLD)and type-2 diabetes mellitus(T2DM)have an intricate bidirectional relationship.Individuals with T2DM,not only have a higher prevalence of non-alcoholic steatosis,but also carry a higher risk of progression to nonalcoholic steatohepatitis.Experts still differ in their recommendations of screening for NAFLD among patients with T2DM.AIM To study the prevalence of NAFLD and advanced fibrosis among our patient population with T2DM.METHODS During the study period(November 2018 to January 2020),59 adult patients with T2DM and 26 non-diabetic control group individuals were recruited prospectively.Patients with known significant liver disease and alcohol use were excluded.Demographic data and lab parameters were recorded.Liver elastography was performed in all patients.RESULTS In the study group comprised of patients with T2DM and normal alanine aminotransferase levels(mean 17.8±7 U/L),81%had hepatic steatosis as diagnosed by elastography.Advanced hepatic fibrosis(stage F3 or F4)was present in 12%of patients with T2DM as compared to none in the control group.Patients with T2DM also had higher number of individuals with grade 3 steatosis[45.8%vs 11.5%,(P<0.00001)and metabolic syndrome(84.7%vs 11.5%,P<0.00001)].CONCLUSION A significant number of patients with T2DM,despite having normal transaminase levels,have NAFLD,grade 3 steatosis and advanced hepatic fibrosis as measured by liver elastography. | Jasbir Makker Hassan Tariq Kishore Kumar Madhavi Ravi Danial Haris Shaikh Vivien Leung Umar Hayat Muhammad T Hassan Harish Patel Suresh Nayudu Sridhar Chilimuri | 2021 | World Journal of Gastroenterology2021，27，6： | 2 |

| 6 | Solution procedure of residue harmonic balance method and its applications显示文摘This paper presents a simple and rigorous solution procedure of residue harmonic balance for predicting the accurate approximation of certain autonomous ordinary differential systems.In this solution procedure,no small parameter is assumed.The harmonic residue of balance equation is separated in two parts at each step.The first part has the same number of Fourier terms as the present order of approximation and the remaining part is used in the subsequent improvement.The corrections are governed by linear ordinary differential equation so that they can be solved easily by means of harmonic balance method again.Three kinds of different differential equations involving general,fractional and delay ordinary differential systems are given as numerical examples respectively.Highly accurate limited cycle frequency and amplitude are captured.The results match well with the exact solutions or numerical solutions for a wide range of control parameters.Comparison with those available shows that the residue harmonic balance solution procedure is very effective for these autonomous differential systems.Moreover,the present method works not only in predicting the amplitude but also the frequency of bifurcated period solution for delay ordinary differential equation. | GUO ZhongJin LEUNG A Y T MA XiaoYan | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，8： | 2 |
