The invention relates to the technical field of road surface maintenance thin overlay, in particular to a surface treatment method for achieving low noise and skid resistance of a road. The surface treatment method adopts the road as a construction object and is characterized in that a construction vehicle is adopted for sequentially and synchronously spraying an interlayer interface agent, modified emulsified asphalt, a skid resistance and noise reduction material, modified emulsified asphalt and a surface protecting agent on the road surface, so that an ultrathin overlay structural layer with the thickness being 2-9 mm is formed on the road surface. The durability, water sealing performance and skid resistance are better than those of sand containing fog sealing layers and micro-surfacing, the travelling vehicle noise is lower than the micro-surfacing and a macadam sealing layer, the problems that rolling stone is likely to appear on a macadam sealing layer, so that travelling safety is affected, and sheet disengagement is likely to appear in the prior art are solved, and the surface treatment method is the ultrathin surface treatment technology with rapid construction and high cost performance.

The invention provides a device for automatically detecting the abrasion of the pantograph pan of a locomotive online. A front trigger switch and a rear trigger switch connected with a data processing and controlling device are fixed to the lateral surface of a detection shed at the height thereof being the same as the pantograph pan; a left background plate and a right background plate are respectively mounted on the left and right lateral surfaces of the detection shed; four image sensors are mounted on the detection shed; wherein a rear left image sensor and a rear right image sensor with the forward and downward viewing angle are respectively aimed at the front parts of the right background plate and the left background plate, and the rear left image sensor and the rear right image sensor are respectively aimed at the right half part and the left half part of a front plate of the pantograph pan of the locomotive when the rear trigger switch is triggered; and a front left image sensor and a front right image sensor with the backward and downward viewing angle are respectively aimed at the rear parts of the right background plate and the left background plate, and the front leftimage sensor and the front right image sensor are respectively aimed at the right half part and the left half part of the pantograph pan of the locomotive when the front trigger switch is triggered. Accordingly, the device capable of carrying out the automatic non-contact dynamic detection on the locomotive online has the advantages of high detection accuracy, safe and convenient application, high stability and reliability and long service life.

The invention discloses a rubber plate for railway level crossings and a rubber hold-down strip thereof, which are laid between two rails of the railway level crossing. The rubber plate comprises a plate main body and two concave trenches, wherein the plate main body is provided with a shoulder on each outer side of the two rails, and also is provided with at least one row of water fittings in parallel; the two concave trenches are respectively arranged on one side of each shoulder and respectively formed by the height difference between the top surface and the shoulder; and a plurality of combining holes are arranged in each concave trench. The rubber hold-down strip has the structure that the hold-down strip body is embedded in the concave trench of the rubber plate; a hollow buffer chamber is formed between the top surface and the bottom surface of the hold-down strip body; and a plurality of fixed bars are formed on the bottom surface of the hold-down strip body, and correspondingly inserted into the combining holes of the rubber plate.

The invention belongs to the technical field of using non-macromolecular organic matter as ingredients in the chemical industry. It uses lactic acid fermentation cell residues and lactic acid to prepare and extract waste liquid as main raw materials, and prepares bacterial residue waste liquids such as amino acid ammonium salts and polypeptide acid ammonium salts, and lactic acid sodium salt waste liquids. and lactate ammonium salt waste liquid, the above three waste liquids were concentrated to obtain acidolysis concentrate, sodium lactate concentrate and lactate ammonium salt concentrate, mixed according to the weight fraction ratio of 30:40:30, and obtained by spray drying. Salt-based organic acid salt environment-friendly deicing agent particles, the whole process is simple, low cost, good economic benefits, no secondary waste liquid and residue, the product can be completely degraded after snow melting, a good solution to the problem of inorganic salt snow melting The disadvantages of lactic acid fermentation can be eliminated, and the waste residue and waste liquid of lactic acid fermentation can be reused, which improves the added value of lactic acid fermentation production.

The embodiments of the invention provide a call control method, which is applied to an electronic device; the electronic device comprises a brain wave sensor, wherein the method comprises the following steps: when it is detected that the electronic device and an automobile central control system are in an interconnection state, switching the control mode of the electronic device into a brain wavecontrol mode; when a pass call request is detected, a brain wave signal of a user is acquired through the brain wave sensor; the passive call request is determined to respond according to the brain wave signal, and a call connection with an active calling party is built. According to the embodiments of the invention, the improvement of the intelligence, the security and the convenience of processing an incoming call request by an electronic device in a vehicle-mounted interconnection state is facilitated.
