A method for fabricating the three-dimensional comb-tooth-shaped groove array surface, the surface of the bearing is first etched with grooves having a certain depth by means of femtosecond lase, then a PTFE film is impressed and attached to the surface of the inner ring of the bearing, the position of a laser focus is adjusted to focus on the lower surface of the PTFE film, the same pit is scanned repeatedly, ripple characteristic stripes occur on the surface of the inner ring of the bearing while the film gasifies instantly under the action of laser ablation heating, a part of polymer material in the gasified part is adsorbed to a mechanical surface in each pit under the action of mechanical interlocking, and a super-oleophobic PTFE surface is obtained in each groove.

Three-dimensional parallel-triangular-shaped groove array surface for bearing and fabricating method thereof

The invention relates to the technical field of agricultural planting, in particular to a special controlled-release microbial fertilizer for peanuts in a continuous cropping field and a preparation method thereof. The fabric comprises an outer layer, a middle layer and an inner layer. Through a three-layer structure, the controlled-release fertilizer prepared by the disclosure can realize the fertilizer efficiency period of 50-60 days, and achieves the purpose of twice releases.

Special controlled-release microbial fertilizer for peanuts in continuous cropping field and preparation method thereof

The invention relates to the technical field of agricultural planting, in particular to a controlled-release bacterial fertilizer for peanuts and a preparation method of the special controlled-release bacterial fertilizer. The special controlled-release bacterial fertilizer is composed of an inner layer and an outer layer; after the outer layer is released completely, the inner-layer network structure gradually absorbs water and preserves moisture, and has good slow release and controlled release properties, thereby achieving the gradual release of the inner layer, high fertilizer utilization rate, exerting the efficacy of the microbial agent and facilitating the large-area promotion.

A device measures a frictional force and a film thickness of a lubricating oil film in different surface velocity directions. The device includes an experiment bench. A translation stage is mounted to the experiment bench, and is linearly movable. A main shaft system is mounted to the experiment bench. A glass disc is mounted to the main shaft system and is rotatable. An arcuate guide rail is disposed on the translation stage. A rotary base is mounted to the arcuate guide rail and is movable along the arcuate guide rail. A loading system is mounted to the rotary base. A steel ball of the loading system and the glass disc are movable relative to each other. A rotary bearing in the rotary base is configured to convert a frictional force generated from the relative movement to a pressure allowed to be collected by a pressure sensor on the rotary base.

A special film-coated controlled release calcium fertilizer for peanut includes a three-layer structure. Raw materials in an inner layer include calcium nitrate, humic acid, seaweed extract and adhesive. Raw materials in an intermediate layer include calcium nitrate, urea formaldehyde powder and chitosan oligosaccharide. Raw materials in an outer layer include urea formaldehyde powder and fermented livestock and poultry manure. The special controlled release calcium fertilizer for peanut releases Ca since the pod-bearing stage after the basal application. The coating film is a biodegradable film, releases calcium since about 50 days after application into soil.
