The invention discloses a method for travelling of motor vehicles at an intersection in a mode of going straight or turning right firstly and then turning left. The motor vehicles travel on a motor vehicle lane in the first direction can go straight without a limit to pass the intersection 0; the motor vehicles travel on a motor vehicle lane in the second direction cannot straightly go through the intersection 0 but can turn right to pass the intersection 0 and then turns left so that any motor vehicle J can directly go straight, or indirectly turn left, or indirectly turn round or indirectly go straight to pass the intersection 0 without a limit, and accordingly the motor vehicles J can easily go through the intersection 0 smoothly. The invention further discloses a specific lane for helping the motor vehicles J to go through the intersection 0 smoothly. The specific lane E comprises the intersection 0, the motor vehicle lane F in the first direction, a forward lane of the motor vehicle lane F, and G'; the G' comprises the motor vehicle lane G in the second direction; and the specific lane E comprises signs for determining the motor vehicle lane F and the motor vehicle lane G.

The invention discloses biomass coal-water slurry prepared by waste leachate and domestic sludge and a preparation process thereof, aiming to provide biomass coal-water slurry with low cost which combines the energy-saving and emission-reducing with environment management and a preparation method thereof. The invention adopts coal, domestic sludge, waste leachate and additives as raw materials toprepare the biomass coal-water slurry which can replace fuel for use by mixing, grinding, homogenizing and filtrating the raw materials, thus saving energy effectively, reducing cost greatly, realizing good management function on the urban environment and reaching the aims of promoting the economic and environmental health and sustainable development. The invention can be widely used in the fields of fuel replace burning for industrial boilers, power station boilers and industrial furnace, the field of urban environmental management and the like.

A high-barrier composite film for a vacuum thermal insulation panel and manufacturing method therefor, characterized in that attached to the outer-most side of the high-barrier film by means of an adhesive agent is a layer of glass fiber cloth. The advantages of the present invention are that: a layer of glass fiber cloth is attached to the outer-most side of the existing high-barrier composite film of the vacuum thermal insulation panel; the glass fiber cloth is scratch resistant and has good affinity with cement, thereby effectively solving the problem of high-barrier films of regular vacuum thermal insulation panels being vulnerable to scratching, stabbing, and aging, and having bad bonding with cement and mortar, and solving the long-standing difficulties of vacuum thermal insulation panels in construction.

The invention relates to a method for fast predicting the grinding quantity of a support roller of a hot rolled plate strip rolling mill, belongs to the technical field of a rolling roller maintenance process and is used for predicating the grinding quantity of the support roller during the roller maintenance by a calculation formula. The method has the technical scheme that a support roller grinding quantity predicating formula is adopted, the constants and the coefficients corresponding to a rolling roller material and a machine frame of the support roller to be ground are substituted into the support roller grinding quantity predicating formula, and the required grinding quantity of the support roller can be obtained. The method can overcome the defects of the grinding method adopted during the support roller maintenance in the prior art, the effect of fast and accurately predicting the reasonable grinding quantity of the support roller to be maintained is realized, the goals of high speed, accuracy and high efficiency in the maintenance process are achieved, after the method is adopted, the consumption quantity of the support roller is obviously changed and is averagely reduced by about 0.03 kg / t. The method has the advantages that the problem of restricting difficulty of the support roller maintenance is solved, the production of the rolling mill is ensured, the maintenance time and the cost are also greatly reduced, and the production cost is reduced.

A high-barrier composite film for a vacuum thermal insulation panel and manufacturing method therefor, characterized in that attached to the outer-most side of the high-barrier film by means of casting is a layer of glass fiber cloth, thereby forming a glass fiber cloth casting composite film. The advantages of the present invention are that: a layer of glass fiber cloth is attached to the outer-most side of the existing high-barrier film of the vacuum thermal insulation panel; the glass fiber cloth is scratch resistant and has good affinity with cement, thereby effectively solving the problem of high-barrier films of regular vacuum thermal insulation panels being vulnerable to scratching, stabbing, and aging, and having bad bonding with cement and mortar, and solving the long-standing difficulties of vacuum thermal insulation panels in construction.

A high-barrier composite film for a vacuum thermal insulation panel and manufacturing method therefor. Both internal and external sides of the high-barrier film is attached with two layers of glass fiber cloth by means of heat sealing, thereby forming a glass fiber cloth composite film. Two layers of glass fiber cloth are attached to the outer-most sides of the existing high-barrier film of the vacuum thermal insulation panel; the glass fiber cloth is scratch resistant and has good affinity with cement, thereby effectively solving the problem of high-barrier films of regular vacuum thermal insulation panels being vulnerable to scratching, stabbing, and aging, and having bad bonding with cement and mortar.

Disclosed are a high-barrier composite membrane for a vacuum insulated panel and a method for manufacturing the high-barrier composite membrane. The high-barrier composite membrane is characterized in that a glass fiber cloth layer is composited on the outermost side of an original high-barrier membrane for the vacuum insulated panel in a heat-sealing mode. The high-barrier composite membrane has the advantages that by the aid of excellent affinity and scratch resistance of glass fiber cloth and cement, the problem that a high-barrier membrane for a conventional vacuum insulated panel is subject to scratch and puncture, is not firmly adhered with cement mortar and is not anti-aging can be effectively solved, and long-standing, big and difficult problems of an existing vacuum insulated panel for building are solved.

The invention relates to a squeezing and rubbing dual high window reciprocal drum washing machine. The biggest and most obvious feature of the machine lies in that a reciprocal rotary conjoined dual drum assembly used is parallely arranged in the horizontal direction at the upper middle part of a machine body, stably hoisted on two sides of a central supported cable-stayed bridge type hanger fixedto a transverse center position of a mounting platform by the hanger, and hinged to and positioned on the mounting platform through plunger damping rods on left and right sides of the bottom of the conjoined dual drum assembly. The main features and advantages of the machine that can best reflect the advantages of the product are: efficient high-quality washing principle and washing method of 'centrifugal squeezing, rubbing and washing for dirt removal, rinsing and dehydration' completely different from 'squeezing and rubbing' of high imitated artificial washing of washing methods of varioustraditional washing machines are used, and left and right 'small-diameter, large-depth, easy-balance and weak vibrating drums' are used for reciprocal rotation, so that partial vibration of a low vibrational energy level can be further offset or greatly reduced; with the use of a brand-new original center-supported conjoined dual drum hanging and hoisting method, the moving parts in the body are completely contactless with the vertical surface and the top surface of an outer case body, thereby ensuring zero vibration of a machine case. The machine also has the advantages of high cleanliness, minimal wear rate, light weight, convenient and safe operation, health care, long service life and the like.
