Finally, the corresponding stress distributions of the slipper are gained by finite element calculation, and the calculation results are shown in Fig.3.
35 MPa 25 MPa
15 MPa 5 MPa
Fig. 3 Stress distribution diagram of the slipper in different working conditions
(35 MPa, 25 MPa, 15 MPa, 5 MPa)
It can be seen from Fig.3 that the stress of the slipper increases with the increase of working pressure of the axial piston pump, when the working pressure of the pump is up to limit pressure of 35 MPa, the maximum stress of the slipper is 155.23 MPa, and it doesn’t exceed the permissible stress of bronze material that is used to make the slipper.

They are used to manufacture chemicals such as solvents
in syntheses, in pulp processing, as preservatives for woods, textiles and leathers and as starting
materials in polymer and pesticide production [1-2].
Adequate anode materials for electrolyses are essential, because the efficiencies of the degradation of organic materials depend on the nature of the anode materials [12].
However, Title of Publication (to be inserted by the publisher) these materials would not be acceptable for wastewater treatment due to their toxicity and limited lifetime, while the notably less toxic noble metal oxides are expensive.
Moreover, for the high treatment efficiency, anode materials having a high current efficiency should be used for the electrochemical treatment.
The standard materials for the HPLC (Supelco, USA) were oxalic acid, succinic acid, malic acid, hydroquinone, phenol and 2- chlorophenol.

Because the 4.6 billion years earth is the source of all life, stratigraphy, rock and its weathered material soil are dominated by geological systems and geological environment, therefore, really known and protected Geological Heritage is protected natural environment, other ecological diversity, ecological structure and ecological environment are also protected.

The sintered material was examined by
XRD and TEM.
Among the most widely studied systems, melt spun Al-Ln-Tm (Ln = lanthanides like Y, and Ce; Tm = transition metals like Ni, V, Cr) are known to develop nanocrystalline/glassy materials having very high strength [6-8].
However, mechanical alloying yields only powders that need to be consolidated into bulk materials before they can have useful mechanical properties.

Research in high temperature materials science including the study of corrosion and
protection behaviour of materials in aggressive environments is widely stimulated by the aim
to increase efficiency of clean electric-power generation plants.
