There is no cementation in marl grain.
When the inclined lower yard construction enter the place 2m far from coal conveying channel , it caused roof collapse in the left side of working face with a large number of mud gushing, leading it unable to continue construction.
Grouting holes arrange around the tunnel face, the number 12.An inspection hole is arranged in the middle of the work surface.

Introduction With the rapid development of the electronics industry, the number of passive components in electronic products gradually increased and the miniaturization of electronic devices is still one of the development trends.
And the large number of defects inside the material and at the interface cause the change of charge distribution so as to promote the charge polarization.

The fine aggregate used was a mixture of tiny grains of rock and granular materials, mainly defined by size, more refined than gravel and coarser than silt.
The vertical axis shows the compressive strength in MPa, while the horizontal axis represents the sample numbers.

The color of the grains ranges from light gray to dark gray depending on the content of impurity components (e.g., iron compounds, unburned particles) [7].
As the analysis shows in comparison with quartz sand, fly-ash as the siliceous component of aerated concrete has a number of advantages.
As known that the addition of gypsum intensify the interaction of Ca(OH)2 and silica, resulting in an increasing number of low-basic calcium hydrosilicates and increases the strength of cement stone [8].

The numerical modelling is tested by experimental work on a number of compositional variants of the newly-developed SCA425+ superalloy, which contains appreciable quantities of Cr.
In order to confirm whether the cast bar contains any grain defect, the bars were macro etched using HCl + 5~10 vol.% H2O2 solution.

Floc fractal dimension changes to better reflect the flocculation level and treatment effect for the establishment of floc fractal dimension number of changes in the coagulation control is provided for reference.
Its not only to the source water turbidity, organism has good removal efficiency, but also its elixir dosing quantity and produces a small amount of sludge, forming the flocculant body close-grained, settlement, speed, giving full play to the inorganic flocculant with organic flocculants respective advantages, it has a good application prospect.

Scrapped number by theoretical calculation could exceed 4 million, and that number will increase every year.
Finally it will obtain the closed grain and polished coating.

This method is mainly for wooden parts produced the arrange grain cracking damaged, the cracking of component is mainly due to the wet to dry state.
The approach is to use number 8 galvanized iron wire at the wood components cracks.
Currently a large number of ancient buildings is needed of reinforcement maintenance, professional and technical personnel to fill the existing severe shortage of professional and technical staff need training.

However, a large number of raw materials with rich sources and low prices cannot be regarded as feedstock for the production of fuel ethanol, such as xylose as one of the main components in lignocellulose, and lactose in whey powder which is a by-product in dairy industry.
To develop and utilize a large number of agricultural by-products such as straws and husks and forestry wastes as feed stock of fuel ethanol each year can not only reduce the production costs, but more importantly broaden the sources of raw materials and reduce grains/sugar consumption.

Corrosion target separation algorithm can be glued together, and small grain noise removal, the expansion of the neighborhood average algorithm. the basic operations was defined as
To find out the differences in the number of images, its each comparison is more complicated.
By treatment of processing of the image difference operator (This article refers to the pixel operations), the results obtained will be able to reflect the differences in a number of images exist, and then through the actual use of artificial conditions, boundaries, ultimately can get the image welding point defects.
