Metaphysics can be distinguished for abstract and concrete metaphysics. The origin 、resource、whole and world prospect of language are different kinds of metaphysics. Their same character lies in different understanding about existence. The concrete understanding about existence requires that the concern on existence relates to the existence of man, overcome the separation between essence and appearance, facilitate time and existence、existence and existencer. The concrete understanding on existence consists concrete metaphysics.

回顾形而上学的历史不难发现,存在着抽象的形而上学与具体的形而上学,从追求存在的始基,到以观念为存在的本源,从预设终极的大全,到建构语言层面的世界图景,构成了抽象的形而上学的不同类型,它们共同的特征在于对存在的抽象理解;对存在的具体理解要求将存在的关注与人的存在联系起来,扬弃形上与形下的分离,克服本质与现象、体与用、一与多之间的悬隔,沟通时间与存在、存在与存在者,对存在的具体理解,构成了形而上学的具体形态。

During the calculation the results got by quintic spline kernel was the best so it was chosen as the proper kernel for the SPH simulation. By comparison of the simulation results got by SPH and finite volume method, it was proved that the buffer cells method proposed in the SPH simulation to implement the Dirichlet boundary conditions was accurate, and this is of great importance for the simulation of flows pass a pipe. At last, the SPH method was improved to simulate the liquid-solid two phase flows and the results show that this method was appropriate for the simulation of flows containing viscous fluid and macroscopic solid components. Now the two methods are both able to predict the continuum flows and rarefied flows severally, but the hybrid program still has some aspects to be improved.

Based on the previous literatures, the following major innovation works were carried out in this dissertation:(1) The derivatization reaction conditions of ephedrine and pseudoephedrine with sensitive derivation reagent in aqueous system were studied and two new methods were developed for the assay of them by microemulsion electrokinetic chromatography and micellar electrokinetic chromatography with LIF detection. The sensitivity and analysis times were greatly improved compared with the previous reports;(2) A new method of CZE with indirect LIF detection was developed for the simultaneous determination of six coumarin compounds (esculin, esculetin, isofraxidin, genistein, naringin and sophoricoside) with fluorescein as the probe.

The function mechanism among the minerals and floatation drugs had been studied with the way of IR and academic calculation, which pointed out that absorption of G-4 on the surface of phosphorite belonged to physical and chemical types, but the chemical one was in the highest flight. Absorption of amine collector named GE-609 on the surface of quartz belonged to electrostatic and physical type. Distilled water could hardly wash the GE-609 down from the surface of quartz. Leading component of S-721 was the concentrated compound of naphthol sulfonic acid and formaldehyde. The compound had a stronger affinity to the Mg~(2+) on surface of dolomite than the Ca2+ on surface of phosphorite, which is the essential reason in the separation of phosphorite and dolomite. The leading components of soluble glass in function were HSiO3 hydronium and F^SiC^ colloid granule.
