The author creates the AutomaticallyDiscriminational Model for the Classification of Sandstones System, thatis to say, people can complete the vastly sample s classification of sandstonesaccurately and swiftly, meantime, diminish the possibility of mortal mistake. Based on the study of the basic sandstone component before embedding, the typeof authigenic mineral, and the forming mechanism of porosity in Upper Paleozoicreservoirs in Ordos basin, the author selects the reasonable experiment objects forWater-Rock Interaction modeling study, designs the relatively reactant and resultantduring the diagenesis period, builds the solid-liquid thermodynamics model with theprinciple of thermodynamic phase equilibrium for kinds of primary minerals (potashfeldspar, albite, anorthite, and pyroxene, hornblende) which dissolve in acidic media,and forms the corresponding thermodynamics test database.

As a result, the author discusses the thermodynamics habitus for the minerals either. With the calculation of the thermodynamics modeling, we run the dissolutionmodeling experiments for primary minerals (potash feldspar, albite, anorthite, andpyroxene, hornblende), which is under the conditions of organic acidic and 20 varietytemperature and pressure. The dissolution modeling experiments include 4 anorthitedissolution experiments, 8 pyroxene dissolution experiments, 8 hornblendedissolution experiments.

An investigation to the microstructure of worn sample of dry vibratable materials for tundish working lining after using 40 hours shows that the materials changes the properties of slag by the chemical filter, increases the viscosity of slag, forms a dense layer at slag/refactories interface, then blocks the more slag penetrate in it. The complex phase formed at the interface, such as magnesiowusite and complex spinel et al, would absorb in more low-melting point minerals, then degrade its melting point and dissolve into slag, which forms low-melting point silicate phase, penetrates into dry vibratable materials along with Monticellite and Merwinite bonding phase by diffusion.

On the basis of a study and elaboration of data, some important conclusions are presented:(1) ruby deposits in marbles occur in the plutonic metamorphic zones of orogens where deep fault structure is developed;(2) ruby-bearing rocks are calcic crystalline marbles, rather than magnesian marbles;(3) amphiboles in ruby-bearing rocks are not tremolites, but silica-poor, alumina-rich and chrome-bearing calcic amphiboles, such as chrome-bearing magnesio-sadanagaites; and (4) the deposits are genetically of thermodynamical metamorphism type, rather than of pneumatolito-hydrothermal type or skarn type.

The results show that in the applied load range of 10250 N, the mass loss rate of coated AZ91D alloy can be identified to three stages, which are related with whether the coating is worn out. Abrasion is the main mechanism for the coated alloy. The friction coefficient of the coated alloy during sliding wear appears oscillation before it reaches a constant value, which is close to the μ value of the matrix alloy. The mass loss rate of coated alloy increases slightly with increasing applied load when the applied load is more than 150 N because of high plastic deformation accommodation on the matrix alloy surface.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
