Furthermore, at the magnification of 10,000, the cementation phenomenon and even tabular grains appeared at the surface of soil.
The further exploration shown, the free iron oxide, silicon, aluminum and other cements, which didn’t stick together with the framework grain but formed a stacked structure having a certain structure of connection power.

This maximum grain size was chosen because it is the most common one in pavement base courses.

Introduction There are also niobium and rare earth rare etc.elements in addition to containing a large number of hematite in Baotou Bayan Obo ore.
Three kind of hematite with different iron grade(No.1 ore with TFe of 42%, No.2 ore with TFe of 30%, No.3 ore with TFe of 17%) from Concentrating Mill of Baotou Iron and Steel Company, grain of -74μm accounts for more than 90% of ores, composition was showed in Table 1; activated carbon, analar , specific surface area of 1033m2/g, a fixed carbon content of 98%, from Shandong Zibo Huaguang Chemical Plant.
The three types of roasting ores were prepared under the above- mentioned best reduction conditions, then ground into powders of 74μm in grain size and made magnetic separation under the magnetic field strength of 80kA/m(the first magnetic separation), the iron grade of concentrate and the recovery were given in Figure 3.
The results showed that iron grade of roasting ores(about 50%) was low after the first magnetic separation, but the iron recovery was very high(reaching over 90%), indirectly reflecting the good effect of microwave reduction roasting, that most of the weak magnetic hematite changed into a strong magnetic magnetite.Then the concentrate after first magnetic separation were ground into powders of -33μm of grain size and made magnetic separation under the magnetic field strength of 32kA/m (the second magnetic separation), the iron grade of concentrate reached about 60%, which met the requirement of iron-making.The results of the second magnetic separation given in Table2.

The walls of the pores were analyzed with energy diffraction spectrum (EDS), and a large number of compounds containing K, F and Mg elements were detected in the wall of large pores (the diameter above 100um).
The grain diameter of welding bead much smaller than that of base metal is equivalent under three different velocities, as proved that the equal solidification rate was produced.
TiB2, distributing in the grain or along the grain boundary, did not vary in comparison with Fig.5.

PVA grains were fully dissolved in water by stirring at 95℃.
A small number of bead-like irregularities appear in the nanofibers spun from solutions with 10 wt% MWNTs concentration.
It was observed that the absorption peak at about 3406 cm-1 concerned with –OH stretching vibrations shifted to a higher wave number with the increase of MWNT content in the blends.

Results and discussion Measurement of recovery stress Recovery stress of Ni47Ti44Nb9 alloy in forging state After different pre-strain in low temperature range (-60℃ ±5℃) for Ni47Ti44Nb9 alloy, the evolution of recovery stress in heating process (increase to 473K) was measured and the result of the samples which were named number 1, 2 and 3 respectively, was shown in Fig1.
As shown in Fig1, when the temperature increase to 423K, the recovery stress of the three samples reached the peak values, which is 212MPa, 215MPa and 210MPa for number 1, 2 and 3 samples respectively.

Among them, a number of studies demonstrated the fabrication of scaffolds with a gradient of mineral content for mimicking the composition and mechanical function of the interface between soft tissue to hard tissue (i.e., tendon-to-bone, ligament-to-bone, and cartilage-to-bone) [3,4].
Our more recent study demonstrated the presence of dopamine in mineralizd solution can tailor the grain size and morphology of minerals deposited to the electrospun fibers [7].

Shrinkage of castings will be increased if the temperature is too high, and the grain will become larger

The number of yellow silicon carbide particles attached to the susceptor surface decreased after exposure at 250 oC, as shown in Figs. 3 (a) and (b).
By the additional etching at 270 oC, most of the silicon carbide particles were detached, but a small number of particles remained, as shown in Fig. 3 (c).
The susceptor surface had ambiguous-shaped shallow hills, which might be related to the grains of the silicon carbide coating film.

After a long research for building " big " high purity Ge spectrometers, we have recorded, starting from 30 years ago, strong efforts for materials like CdTe, which only now is really commercial; 10 years ago, epitaxial GaAs and even more recently SiC came into play for other kinds of application, since for gamma ray spectroscopy their atomic numbers were too low.
Polycrystalline materials like CVD diamond displayed in the past non-uniform cce maps, in which it was easy to notice the appearance of single grains.
Moreover, the presence of traps in the defective regions around the grain boundaries caused strong polarization effects which in practice impeded in many cases to get reasonable cce maps.
Even after a priming of 10 Gy of X-rays the sample showed polarization effects in times of the order of few minutes: cce distribution was quite non-uniform, displaying the morphology of grains according to their local values of cce and, moreover, energy resolution was extremely bad, since the multichannel pulse spectrum - displayed at bottom right - showed a very broad band.
The number of events above the threshold also decays from 573 to 506, i. e. of about 11 %.
