The invention discloses a method for producing hot rolled ribbed bars by controlling austenite strain accumulation after finished rolling. The method is characterized in that: deformation and recrystallization behaviors of the austenite are controlled in the rolling process, so that the deformation accumulation of the austenite after finished rolling is controlled in 80 to 99 percent of an austenite dynamic recrystallization critical strain range, and the cooling strength of spray cooling after rolling is controlled to inhibit the static recrystallization of the austenite. By controlling the deformation temperature, strain speed and rolling reduction of a finished rolling pass, strain accumulation required by strain induced transformation is obtained, and is matched with cooling time from the finished rolling to spray cooling and the spray cooling strength to refine ferrite grains on the surfaces to be 4-7 micrometers; and the method is an advanced process for producing high strength tempered martensite-free hot rolled bars, and has obvious technical innovation.

The invention discloses a northeast colored pheasant and native chicken hybridization and improvement method, and relates to cultivation method for poultry new species. The northeast colored pheasantand native chicken hybridization and improvement method comprises the following steps: selecting a female native chicken and a male northeast colored pheasant, carrying out mixed culture to lay eggs naturally, and hatching fertile eggs to obtain first F1-generation hybrid chickens; selecting a male native chicken and female northeast colored pheasant, carrying out mixed culture to lay eggs naturally, and hatching fertile eggs to obtain second F1-generation hybrid chickens; hybridizing by using the first F1-generation hybrid chickens as female parents and male northeast colored pheasants as male parents to obtain F2-generation hybrid chicken; and hybridizing by using the F2-generation hybrid chickens as female parents and taking the second F1-generaton hybrid chickens as male parents to obtain hybrid pheasant new species. The production performance of the obtained hybrid pheasant new species can be greatly improved, the hybrid pheasant new species are high in disease resistance, wide inadaptation, is heavily gamey and nutrient-rich, and has rich texture, and thus, the northeast colored pheasant and native chicken hybridization and improvement method has the characteristics of low feeding cost, large market sales volume and high profit.

The invention discloses a water heating machine system of a heat recovery multi-gang heat pump air conditioner, which comprises a compressor, a three-way valve, an outdoor heat exchanger, an indoor heat exchanger, and a plurality of electronic expansion valves, branch pipes and electromagnetic valves. One end of the three-way valve is communicated with a high-pressure air pipe of the compressor; the other end of the three-way valve is communicated with the outdoor heat exchanger, the electronic expansion valves, the branch pipes and the indoor heat exchanger in sequence; and the high-pressure air pipe and a high-pressure liquid pipe of the compressor are respectively connected with a water heating tank through the branch pipes and the electronic expansion valves. By using the water heating machine system, the breakover or the turning off of the electromagnetic valves is controlled through an electric control device to switch the communication of a low-pressure air pipe, the high-pressure air pipe and the indoor heat exchanger, so that the indoor heat exchanger can carry out refrigeration or heating, and the breakover or the turning off of the electromagnetic valves is controlled through the electric control device, so that the high-pressure air pipe and the water heating tank are subjected to the breakover or are turned off and the water heating tank can heat water. By adopting the way, through the whole system, the running of three basic modes, namely, air conditioner refrigeration, air conditioner heating and water heating, can be achieved simultaneously.

The invention relates to a multiple heat pump air-conditioning water heater which comprises a compressor, three-way valves, an outdoor heat exchanger, an indoor heat exchanger, a plurality of electronic expansion valves, a branch pipe and an electromagnetic valve; one end of each three-way valve is communicated with a high-pressure air pipe of the compressor, and the other end of the three-way valve is communicated with the outdoor heat exchanger, the electronic expansion valves, the branch pipe and the indoor heat exchanger in sequence; the high-pressure air pipe and a high-pressure liquid pipe of the compressor are respectively connected with the branch pipe, the electronic expansion valves, the electromagnetic valve and a water-fluoride heat exchanger; the water-fluoride heat exchangeris connected with a water storage tank through a water pump; the three-way valves are two in quantity, and the two three-way valves are connected mutually in parallel and form a connecting loop together with the compressor. In the invention, an electric control device controls on or off switch of the electromagnetic valve and the communication of a low-pressure air pipe, the high-pressure air pipeand the indoor heat exchanger so that the indoor heat exchanger can refrigerate or heat; the electric control device controls the electromagnetic valve to be powered on or off so that the high-pressure air pipe and the water-fluoride heat exchanger are powered on or off and the water-fluoride heat exchanger can heat water, thereby realizing the simultaneous operation of three basic modes: namely,air-conditioning refrigeration, air-conditioning heating and hot water production.

The invention discloses a noble concubine chicken and Guizhou mountain colorful chicken hybrid breeding method. A chicken of a noble concubine chicken and Guizhou mountain colorful chicken hybrid variety bred by the method has the characteristics that the chicken is easy to feed, is moderate in lively character, does not jump or fly around chaotically, is extensive in food range, can eat coarse fodders and also likes to eat insects in fields, a process from hatching an egg to breeding a chick into the edible chicken takes only three months, and the duration of the process is shortened as compared with an original noble concubine chicken and an original Guizhou mountain colorful chicken.
