A polycrystalline diamond abrasive cutting element consists generally of a layer of high grade polycrystalline diamond bonded to a cemented carbide substrate. The polycrystalline diamond layer has a working surface and an outer peripheral surface and is characterized by having an annular region or a portion thereof adjacent the peripheral surface that is lean in catalyzing material. A region adjacent the working surface is also lean in catalyzing material such that in use, as a wear scar develops, both the leading edge and the trailing edge thereof are located in a region lean in catalyzing material.

The invention discloses a method for embankment by blasting and silt squeezing on a complex soft foundation, which is characterized by: taking advantage of the characteristics of ocean tide rising and falling, using the depth of covering water instead of a resistance line in blasting, applying most energy onto the top face of the complex soft foundation, squeezing down the complex soft foundation, adopting the combined action of blasting at a dyke head or on two sides of a dyke and other various blasting modes at the same time, continuously squeezing down jackstones by using the gravity of the jackstone dyke body under the action of explosion shock to remove the silt soft foundation under the jackstones, allowing the stone layer of the dyke body to fall onto bottom to form a sea dyke cross-section meeting design requirements, allowing two sides of the dyke body to fall onto the ground completely with certain ground width, and ensuring the stability of the dyke body; and avoiding landslip frequently occurring in on-site backfill and direct random sea dyke fill, as well as increasing embankment construction speed, reducing cost by 50 to 90 percent and achieving considerable economic benefits compared with a processing method which is to first excavate soft foundation and then fill back.

A foamed stone article has a lower artificial stone layer and an upper foam layer that are a single body. A composition for the foamed stone article includes about 100 parts by weight of acrylic resin, about 10 to about 80 parts by weight of solid particles and about 0.1 to about 10 parts by weight of an initiator.

The invention provides a salt-water and fresh-water root-divided alternative irrigation method. A salt isolating layer is adopted, sequentially comprises a rubble layer, a reed layer, a fine stone layer and a mixed soil layer from bottom to top, and is laid on a planting area. The upper surface of the salt isolating layer is 100 cm to 140 cm away from the earth surface. The rubble layer is prepared fromvermiculite, ceramsite and coarse sand, the fine stone layer is prepared from powdered rock phosphate, biogas residues and wheat bran, and the mixed soil layer is prepared from Luzhao soil and Chiyu soil. The invention further provides an application of the salt-water and fresh-water root-divided alternative irrigation method to planting of tall ligustrum lucidum in saline and alkaline land. By means of the root-divided alternative irrigation method, the growing speed of plants is increased, and the medical value of plants is increased; taking tall ligustrum lucidum as an example, the content of ursolic acid in fruits of tall ligustrum lucidum is 30% to 33%; the capacity of absorbing toxic gas of plants is improved, and the environment is purified.

A conical structure of cubic Boron Nitride (cBN) is formed on a diamond layered substrate. A method of forming the cBN structure includes steps of (a) forming diamond nuclei on a substrate, (b) growing a layer of diamond film on the substrate, (c) depositing a cBN film on said diamond layer, (d) pre-depositing nanoscale etching masks on the cBN film, and (e) etching the deposited cBN film. In particular, though not exclusively, the cubic Boron Nitride structure has great potential applications in probe analytical and testing techniques including scanning probe microscopy (SPM) and nanoindentation, nanomechanics and nanomachining in progressing microelectromechanical system (MEMS) and nanoelectyromechanical system (NEMS) devices, field electron emission, vacuum microelectronic devices, sensors and different electrode systems including those used in electrochemistry.

The invention discloses a modularized ecological stagnant water revetment for conserving water and soil. The modularized ecological stagnant water revetment for conserving water and soil comprises supporting vertical plates; a row of the multiple supporting vertical plates are uniformly distributed on slopes on two sides of a river channel; rough stone layers are respectively paved on the slopes on the outer sides of the supporting vertical plates; fine stone layers are paved on the top sides of the rough stone layers; planting soil layers are paved on the top sides of the fine stone layers; the front end and the rear end of the outer sides of the outermost supporting vertical plates are fixedly and respectively connected with the inner sides of first partition plates; and the outer sidesand the bottom sides of the first partition plates are sequentially buried into slope soil and planting soil. According to the modularized ecological stagnant water revetment for conserving water andsoil, the structure is simple, the conception is ingenious, a multi-stage water storage device is arranged, so that flowing water temporarily exists on the top sides of the planting soil, the absorption of the flowing water by the planting soil is facilitated, the flowing water can permeate to underground through the planting soil, the impact of the flowing water on the planting soil can be sloweddown, meanwhile, soil carried in the flowing water is conveniently precipitated on the top sides of the planting soil, the flowing water is improved by utilizing a siphon phenomenon, the potential energy of the flowing water is improved to generate electricity, the high order position potential energy of the flowing water can be utilized, and the actual requirement can be met.

The invention relates to a stone-like colorful coating and a manufacturing method thereof. The stone-like colorful coating comprises a bottom plate, a sealing layer, a bottom color layer, a stone-likelayer and a finishing coat that are arranged successively from bottom to top. In addition, according to manufacturing method, the heating and drying processes are reduced by being compared with the existing ones; and thus the efficiency is improved. Since the stone-like colorful dry plate is used for replacing the conventional stone-like-effect coating composition, on the one hand, the heating and drying process of the stone-like-effect coating is removed; and on the other hand, with the stone-like colorful dry plate, the operating place is not easy to pollute and is convenient to clean. Because the stone-like colorful dry plate is able to absorb the moisture of a next bottom color coating, on the one hand, the time for the heating and drying process is shortened and the energy consumption is reduced; and on the other hand, no bulging is caused during the heating and drying operation, so that a technical problem that the bulging is caused easily by the water-based paint during the integrated plate processing in existing production is solved.

The invention discloses a river and lake water greening and purifying method. A groove structure formed by porous concrete is used as a main body; a vegetation pad and a water purifying material are configured in the groove structure; an aquatic plant is planted on the vegetation pad, and water treatment microorganism is applied into the groove; the groove formed by porous concrete, the vegetation pad and the water purifying layer together serve as a carrier for adding aerobic or facultative water treatment microorganism. Freestone is paved at the bottom in the groove structure; a vegetable fiber planar pad, the water purifying layer and another vegetation fiber plane pad are sequentially placed on the freestone layer. The cross section of the structure is in a U shape. The device disclosed by the invention has the advantages of simple structure, convenience in construction, low cost and the like; the device is arranged on the two sides or bridge side of a river, a lake or a landscape pool, and two major aims of water purifying and greening are achieved at the same time.
