An Electroacoustic Investigation of Concentrated Aqueous Suspensions of Calcium Pyrophosphate

The zeta potential of concentrated suspensions of calcium pyrophosphate were investigated using electroacoustics. The particles were negatively charged over the entire pH range studied. It proved impossible to reduce the pH of the suspension below 1.8, but the iso electric point could be estimated to occur at approximately pH 1. Two commercially available dispersants (one cationic and one anionic) were then added in small increments to the suspension in order to follow the change in zeta potential as the dispersants adsorbed onto the particles. From the shape of the curve it was possible to estimate the optimum adsorbed amount of dispersant required to fully coat the particles. The cationic dispersant adsorbed strongly and the optimum dosage was estimated at 2.5 ml of active polymer/kg of powder. Anionic dispersants are known to adsorb onto negatively charged ceramic oxide particles, but the anionic dispersant used in this study did not adsorb onto the negatively charged calcium pyrophosphate particles.

以汤川核力场为例，说明用有效势方法讨论有心力场中圆形轨道的稳定性，数学处理比较简明，物理图象也比较清晰。进而指出非径向微扰引起的速度矩变化对稳定圆轨道半径ｒ＿０的影响，导出两者变化的数量关系，说明在汤川核力场中维持稳定圆运动对微扰量所加的限制。     

心肌动作电位对心脏节律的影响

采用数值方法分析心肌动作电位对心脏节律的影响。心肌动作电位用Noble模型来描述，心脏节律用Bernardo-Signorint模型来模拟。数值分析结果表明，心肌动作电位形成的靶环波和螺旋波对心脏节律影响较大。当心肌动作电位表现为噪声时，心脏节律可完全破坏。

On new forms of motive differential equations of a mechanical system relative to non-inertial frame

Based on D'Alembert's principle of a mechanical system relative to non-inertial frame and by introducing the concept of the generalized inertial potential, new forms of differential equations of motion of a mechanical system with holonomic and the non-holonomic constraints relative to the non-inertial frame are obtained. The merits and demerits between our method and the Newtonian dynamic method as well as the analytic dynamic method are discussed comparatively. Finally, two examples are given to illustrate the application of the motive differential equations in the new forms.
