Major gold occurs as fine-and microfine-grained nature gold encapsulated in limonite, quartz and chlorite.
Gold encapsulated in limonite occurs mainly in the shape of fissure gold, interparticle gold are taken the second place, their size relatively coarse, generally for 10~30µm. a small number of inclusion gold with size under 5µm.

It can be seen, in Fig. 3, that there were no obvious difference, such as the position, height, width and number of the peaks, for the XRD spectra of the ceramics with the addition of Sm2O3 or not.
The microstructure of the specimens were presented in Fig. 4, which revealed that grains in the ceramics demonstrate plate-like shape and randomly distributed with size of 2 to 6 µm.

The XRD pattern indicates that the grain size decreases and the crystalline becomes well with the increasing of reaction time.
If the nucleation rate is higher, the number of particles generated will be larger while the size of the final particles will be relatively smaller.

Visually, the surfaces after experimentation and SEM sample preparation for imaging are coarser, have an increased surface roughness, and have more defined grain boundaries.
Characteristically, white deposits are visible on the surface of these alloys, with pronounced grain boundaries after the 72-hour period.
Thus, the 85% extract concentration increased the number of fibroblast cells by 57% because it contained a higher concentration of copper, as compared to the 65% extract concentration which only increased the number of fibroblast cells by 17%.

Oil shale is belongs to sapropelic coal, which is composed with Fine-grained and sedimentary rock containing solid flammable organic, meanwhile, which is the natural mineral formed by the animal remains through corruption and coalification [3,4].
It is probably because that the roughness degree of the sample‘s surface was high, and the area and the number of holes in the surface of oil shale char was bigger than oil shale after the same modification, it is benefit for the H2S’s absorption to modification ash.
The number of surface area and the pore volume are supposed to play an important role.

Introduction Many recent studies in materials science have focused on ivestigation of materials with a structure containing a large number of individual objects.
The principle of it was generating a large number of spheres with chosen diameter with Gaussian distribution.

The seed fell into grain tube from the feed tongue tube and then were imported into the opener.
The number of seed of every turn is basically stable, which has a linear relationship with working length. 1-feed cup 2- block set 3- feed tongue 4- feed end ring  5-seeding shaft 6- feed roller Fig.2 Structure of outer-fluted feed Rotary Knife Roller Structure [4].

In order to improve the grain production and ensure food security, it is necessary to focus on the study of upland rice high-yield cultivation techniques[1].
Data collections include cultivated area, type of land, crop yield, number of machine, labor input, pesticide quantity, fertilizer use, etc. 2.3 Status of upland rice cultivation As Table 1 shows the state of art of the upland rice cultivation in Lancang.
With the second highest yield is group D, large arable land in the plain or flat area is more suitable for the implement of mechanization, although the number of machines are smaller than that of group A which might be caused by the usage of large-sized machine.
