Background Cor pulmonale is often associated with changes of structure and function of the right ventricle （RV） and thus further affects functional changes of the left *** study aimed to assess the left ventricular （LV） and RV function in patients with cor pulmonale using high-definition CT （HDCT）.Methods We prospectively studied 18 cor pulmonale patients determined by the pulmonary function test,clinical examination,chest radiograph,electrocardiogram,and *** subject group was compared to a control group consisting of 18 *** RV and LV functions and RV myocardial mass （MM） were obtained by HDCT in the two *** results were compared between the two groups using the independent sample t *** examination for cardiac function analysis was performed on the same *** The RV end-diastolic volume （EDV）,RV end-systolic volume （ESV） and RV myocardial mass were significantly larger in the 18 cor pulmonale patients than in the control group （P〈0.05）.The right ventricular ejection fraction （RVEF） was significantly lower in the 18 cor pulmonale patients than in controls （P〈0.01）.The left ventricular EDV （LVEDV） and LVEF were significantly lower in cor pulmonale patients than in controls （P〈0.01）.There were strong correlations between MDCT and echocardiography,rRVEF=0.839 and rLVEF=0.916,*** HDCT can accurately quantify RV and LV *** right ventricular function is impaired in patients with cor pulmonale,while at the same time the left ventricular function is also impaired.

The very peculiar spinose psyllids Togepsylla with only two species were described from China and Japan by Satoru Kuwayama (1931, 1949), R. Takahashi (1936) and Y. Miyatake (1970). Two more species discovered by the authors from China (Fujian and Tibet) are described as new, and a new genus is added. The type specimens are deposited in the insect collections of Beijing Agricultural University. Genus Togepsylla Kuwayama 1931 Type sp.: T. takahashii Kuwayama.

The genus Trichochermes Kirkaldy (1904)originally contains seven describedspecies, but since T. bicolor Kuwayama, and T. hyalina Kuwayama have beentransfered to Petalolyma Scott(1882)recently (yang & li, 1984),and theSouth African species T. insleyae Capener (1973)seems not to be a member ofthis genus, there are only five species *** type species *** (Fors-

The lerp-forming psyllids is very common in the Australian region, such as Spondy?iaspis (Signore, 1879), Cardiaspina (Crawford, 1911), Glycaspis and Hyalinaspis (Taylor, 1960), all of them with bipartite proctigers in the males. On the basis of some morphological and biological characters they should stand for a peculiar subfamily Spendyliaspinae of the Psyllidae (Heslop-Harrison, 1954). In the Palaearctic region two Japanese species were identified as Pachypsylla japonica and P. usubai by Y. Miyatake (1968, 1980) recently, and the nymph, the gall the lerp collected by F.

针对湿式离合器在接合过程中的摩擦振颤问题,通过建立四自由度动力传动系统动力学模型及推导由摩擦效应引起的综合导入阻尼,基于特征值分析,获得系统的稳定性条件.通过Matlab/Simulink仿真研究了摩擦因数、控制油压历程、转动惯量和传动轴刚度等对离合器摩擦振颤的影响.结果表明:由摩擦因数和控制油压历程决定的综合导入阻尼为负时,系统失去稳定性.同时,控制油压先快后慢的上升方式、增大离合器从动部分转动惯量及增加输出轴刚度均可不同程度地抑制摩擦振颤.
