To increase the open-circuit photovoltage (Voc) of a cell, several research groups attempted to improve the properties of the electrodes by adapting the structure of TiO2.

In this paper, the evolution of surface structure and wettability of Ti3SiC2 under short-term LBE corrosion were studied experimentally.

It takes several researching methods, such as XRD，SEM，EDS and UV-vis, etc, to study the structure, composition and spectral features of the product.
Fig. 3 a) Low (a), high (b) magnification SEM images, EDS spectrum , (c) and corresponding HRTEM image (d) of Cu2O-2 sample For comparison, the surface features of samples are analysed, Figure 3a and 3b are SEM spectrogram of Cu2O-2 which are prepared by coprecipitation method, as can be seen from the graph, the obtained product has no specific appearance, at the same time there appears to be products in polyhedral structure as well as a large number of spindle structure nanoparticles.
Figure 2d is a partial high resolution spectrogram of spindle-shaped structure Cu2O, crystal plane spacing is 0.25nM, which is the crystal plane of Cu2O ( 111) .The differences of the appearance of the products obtained by two methods is formed because of following reasons.

For Rhombohedral structure, the calcium insertion on the A site presents a random variation on the structure parameters, mainly taking in account the lower phase amount found in these samples.
The R factor reveals the structure concordance with the structure model adopted.

The failure form is mainly caused by facture, torsion and abrasion. 1.2 Analysis on structure characteristics and manufacture difficulties The crankshaft structure of a large discharge and high pressure emulsification pump is usually determined as three-support and five-crankpins, as is shown in fig 1.
Regarding its structure, the crankshaft is a kind of multi-rotary-axis and slim part.
