桉树扦插育苗正交试验设计分析

根据扦插育苗试验表明，影响泰国赤桉苗高、根长及发根数的主要因素各不相同。综合分析表明：其主要因素是ＢＡ浓度，插条浸泡药液的时间和蔗糖浓度，其较优的插条处理方法是将插条在０．６％蔗糖＋３００ＰＰｍＩＢＡ溶液中浸泡２小时     

A continuum theory of dense suspensions

A continuum theory is introduced for viscous fluids carrying dense suspensions (such as blood) or emulsions of arbitrary shape and inertia. Suspended particles possess microinertia that make the mixture an anisotropic fluid whose viscosity changes with motion and orientation of suspensions. The microinertia balance law coupled with the equations of motion of an anisotropic fluid govern the ultimate outcome. By means of the second law of thermodynamics, constitutive equations are obtained in terms of the frame-independent tensors. In a special case, a theory of bar-like suspensions is obtained. The field equations, boundary and initial conditions are given for both the arbitrarily-shaped suspensions and the bar-like suspensions. The theory is demonstrated with the solution of the channel flow problem. The mean viscosity of the fluid with suspensions is determined. The motions of suspensions down flow are demonstrated.     

Morphometric model of lymphocyte as applied to scanning flow cytometry

The peripheral blood lymphocytes of normal individuals are investigated by methods of specialized light microscopy. Lymphocytes as a whole and T-cell subpopulation are considered. Lymphocyte structure is characterized with reference to polarizing scanning flow cytometry. The lymphocyte and lymphocyte nucleus shapes are analyzed. Linear correlation dependence between sizes of lymphocyte and its nucleus is indicated. A morphometric model of a lymphocyte is constructed using the obtained data. The findings can be used, for instance, as input parameters to solve the direct and inverse light-scattering problems of turbidimetry, nephelometry, and flow cytometry.     

Application of Chimera grid to modelling cell motion and aggregation in a narrow tube

A computational scheme using the Chimera grid method is presented for simulation of three‐dimensional motion and aggregation of two red blood cells (RBCs) in a narrow tube. The cells are modelled as rigid ellipsoidal particles; the computational scheme is applicable to deformable fluid‐filled particles. Attractive energy between two RBCs is modelled by a depletion interaction theory and used for simulating aggregation of two cells. Through the simulation, we show that the Chimera grid method is applicable to the simulation of three‐dimensional motion and aggregation of multiple RBCs in a microvessel and microvascular network.

肝硬化合并低氧血症31例临床研究

为探讨肝硬化患者的血氧变化与临床关系，以肝炎后肝硬化患者31例为观察组（A组），采用血气分析仪测定其动脉血氧分压（PaO2)及动脉血氧饱和度（SaO2)，并以正常人15例作对照组（B组）进行比较结果表明，A组的低氧血症发生率为41％，B组为0。肝硬化患者低氧血症的发生率高，其严重程度与Child-Pugh分级有关。早期发现低氧血症并予以治疗有助于改善肝硬化患者的预后。

采用静脉内弱激光照射血液疗法（ILIB）治疗32例帕金森氏病患者，总有效率达87．6％。作者推测，ILIB可能通过改善脑微循环，纠正脑内多巴胺代谢紊乱从而防治帕金森氏病。     

Optimizing inputs for diagnosis of diabetes. I. Fitting a minimal model to data

A glucose tolerance test was performed on dogs by injecting glucose intravenously and measuring the plasma glucose and insulin concentrations versus time. Various analytical and computational techniques were utilized to fit the data to a minimal model and to estimate the parameters of the blood glucose regulation process. A relatively good fit was obtained in spite of the rather simple model.Animal experiments were funded by the National Institute of Health Grant No. AM-17236 awarded to Dr. R. N. Bergman at U.S.C.
