Ever before, clay is often taken as the material of the core of earth rockfill dam.
More and more construction experiences in China and abroad show that it is a trend to use gravelly soil as core material in high earth rockfill dam [1].
Although many scholars and engineers paid attention to the gravelly soil as core material recently [2,3,4,5], few of them were on the behavior for soils with different percentages of gravel by triaxial test.
Test materials and methods The tested material in this paper is a cohesive soil mixing with gravel, and the cohesive soil and gravel were taken from the site of Shuangjiangkou earth rockfill dam to be constructed in western China.

However, each approach also has limitations either in capability for higher aspect ratio features, material compatibility or cost.
Advanced polymer materials that are effective in preventing pattern collapse during wafer cleaning, suitable for removal by dry ashing processes, both plasma and thermal, are presented.
The ability to remove sacrificial polymer fill material from the wafer pattern without using dry plasma ashing is advantageous when surface damage or material compatibility is a concern.
A key property of thermally activated materials considered for pattern collapse prevention include phase change properties that allow the polymer to be cured and stable within one temperature range while completely degradable in a second temperature range.

Mechanism of Diamond Wire Saw Slicing SiCp-Al Composites
SiCp/Al composites are a kind of two-phase materials with Al matrix and SiC reinforced particles.
The machining way of diamond wire saw slicing SiCp-Al composites is different from that of diamond wire saw slicing ordinary single elastic-plastic material.
This is because that workpiece feed speed increases, the material removal rate increases.

For the basis of the NASICON structure, researchers have substituted other elements to replace Zr, P or Si., the other research creates replacement materials to produce divalent and trivalent ions, such as Al3+ or Mg2+ [9].
The raw materials were ball-milled for 2 hours, dried at 80°C for 12 hours, then calcined in air at 1125°C for 12h with heating rate of 2°C.min-1.

Cluster I composed of all materials that came from the USA, Canada, LanZhou and 4 materials that came from Russia.
The materials which had close relationship were located near.
It mainly showed in that the all materials which came from Kazakhstan and the materials which came from the Russia except 3 materials from Sakhalin and 1 material from Samarra were clustered in the same group when the GS was 0.7.
Finally,the materials from the same place had the similar genetypes.
This study showed that there was the abundant genetic background in Phalaris arundinacea Linn materials and there was a further genetic distance between the materials.

Gunn (1972) [3] first grouped destination image into two factors: (1) organic image, which indicated tourists’ impression of a destination without physically having visited the place; (2) induced image, which is formed through promotional materials or actual visitation.
