A wildfire suppression system is shown that includes a detector that can identify a wildfire threat from an approaching wildfire. When a wildfire is detected, a fire suppression system is activated to pump a fire retardant product, such as water or foam, through a fire retardant distribution system to supply the fire retardant to a series of water dispersion devices that are positioned to protect a structure and a set of landscape elements such as trees, flowers, bushes, and shrubs. Various embodiments can include automatic notification to local fire and police authorities of the presence of the wildfire, and can also include local electrical power generating units that can provide the electrical power needed to operate and control the wildfire suppression system.

The invention is a conversion catalyzer of half-synthetical hydrocarbon, containing denaturing nano alumina. It disperses synthetic molecular screen and denaturing nano alumina containing Ce, Zr and Mg to inorganic oxide clay and natural aluminium silicate clay, mixes into serum, and makes jet-drying shaping, washing and drying to get the conversion catalyzer.

The treatment method comprises the following steps that S1, surveying and setting out are carried out, and the position of a secondary excavation foundation pit is determined; S2, supporting piles and a waterproof curtain are constructed; S3, a foundation pit is excavated; S4, the soil surface is excavated to a preset elevation and flattened, and a submersible pump is placed to pump and drain accumulated water; S5, water and sand gushing points on the soil surface of the substrate are found out, and a water flowing pipeline is built by using bricks, so that water flowing out of the water gushing points is collected to a middle dewatering well to be discharged; S6, a formwork and plastic cloth are laid on the top faces of the bricks; S7, a water stop steel shaft is installed in the dewatering well, and a cushion layer is poured;S8 a waterproof layer is laid, and concrete is poured; and S9, the dewatering well is plugged. According to the substrate water gushing and sand gushing treatment method, the bottom surface of the foundation pit can be rapidly and effectively sealed, the harmful effect of water gushing and sand gushing of the substrate on the foundation pit is restrained to a large extent, and safe and smooth construction of a main body reinforced concrete structure is guaranteed; and the construction method is simple, low in cost and remarkable in effect.

The invention relates to a ready-to-eat large yellow croaker vacuum deep-fried food. The raw materials of the ready-to-eat large yellow croaker vacuum fried food comprise the following components in parts by weight: 120-150 parts of fish meat of large yellow croakers, 20-35 parts of bone glue, 10-25 parts of pomelo peel, 3-5 parts of olive oil, 4-7 parts of corn oil, 5-15 parts of seasonings, 20-35 parts of black bean powder, 10-20 parts of honeycombs, 25-45 parts of nori and sesame seed powder, 2-5 parts of lemons, 5-9 parts of an additive, 5-10 parts of okra, 5-10 parts of ginseng fruits and 5-10 parts of arctium lappa. According to the ready-to-eat large yellow croaker vacuum deep-fried food disclosed by the invention, a vacuum deep-frying manner is used for replacing a conventional high-temperature deep-frying technology, so that the loss of nutrient substances is greatly reduced, the detrimental effects of microbes and enzymes are restrained, and the original fragrance and the original nutrition are sufficiently reserved. The ready-to-eat large yellow croakers prepared by the production technology disclosed by the invention are good in mouth feel, long in storage period, free from preservatives, convenient to eat and carry and simple in production method and technology, and industrialized production is easy to realize.

The invention belongs to the field of processing of aquatic products, and relates to a processing method of crangon affinis meat. The processing method comprises the following steps of performing vacuum deep-frying on pretreated crangon affinis meat, wherein the vacuum deep-frying temperature is 80-120 DEG C, the deep-frying time is 6-10min, the negative pressure of vacuum degree is 0.098-0.08MPa,and the pretreatment of the crangon affinis meat comprises the following steps of sequentially performing low-temperature rinsing on crangon affinis, removing heads, shells and intestinal glands, cutting apart backs, keeping tails, performing low-temperature rinsing, performing soaking in salt water, performing pre-cooking, performing powder pre-wrapping, performing pulp wrapping, performing bread crumb wrapping and performing cold storage. In the pulp pre-wrapping process of the crangon affinis meat, ingredients are in reasonable compatibility, so that pre-wrapped pulp is rich in high cellulose, multivitamins and trace elements, the pre-wrapped pulp is better matched with the crangon affinis meat to obtain more nutrition, and the nutritive structure of deep-fried foods can be improved; and then through pre-cooking, powder pre-wrapping, pulp wrapping, cold storage and deep-frying, the running off of nutrient substances can be greatly reduced, detrimental effects of microorganisms andenzymes can also be restrained, and the original fragrance, the original nutrition and the original meat quality are sufficiently maintained.

The invention discloses a high-toughness and high-red-hardness high-speed tool steel which is characterized by comprising the following components by weight percent: 1.2-1.5% of C, 0.2-0.6% of Si, 4.5-5.5% of Cr, 3.5-4.0% of Mo, 0.8-1.5% of V, 1.5-4.5% of W, 0.2-0.8% of Mn, 0.08-1.0% of Zr, 0.1-0.7% of Al, 0.15-1.5% of Re, 0.02-0.1% of N, less than 0.015% of S, less than 0.03% of P and the balance of Fe and trace impurity elements. The high-toughness and high-red-hardness high-speed tool steel has the red hardness and toughness reaching M42 index and does not contain noble element Co; the cost of the high-toughness and high-red-hardness high-speed tool steel is close to that of M2 high-speed steel, but the performances of the high-toughness and high-red-hardness high-speed tool steel are superior to those of the M2 high-speed steel, so that the high-toughness and high-red-hardness high-speed tool steel can be used for replacing M2 and M42 high-speed steel to manufacture high-precision tools and moulds.

The invention discloses a catalytic conversion method for producing high-octane petrol from crude oil. The catalytic conversion method comprises the following step of: blending and reacting pretreated crude oil serving as raw material oil and a large pore zeolite-containing catalyst in a catalytic conversion reactor, wherein a reaction temperature, an oil gas retention time and a weight ratio of the catalyst to the raw material oil are enough to obtain a reaction product which contains catalytic wax oil which accounts for 15 percent to 60 percent of the raw material oil; the weight houly space velocity is 25 to 100 hour <-1>; the reaction temperature is between 450 and 600 DEG C; and the weight ratio of the catalyst to the raw material oil is 1 to 30. While inferior crude oil is conversed into high-octane petrol by the method, the production rate of dry gas and coke is highly reduced, so that highly effective utilization of an oil resource is achieved.
