Background technology

Along with the development of environmental protection, incity, city ecotope is improved.The trend of showed increased has all appearred in birds, fish, insect etc. in city and suburb.On the other hand, good ecotope also makes more hornet's nest appear at densely populated area.Hornet formal name used at school wasp is commonly called as hornet, wasp, in to large-scale, the body surface majority is smooth, and piebald of all kinds is arranged.Hornet toxicity is very big, and the venom of its sting contains phosphatidase, hyaluronidase and a kind of albumen that is called asantigen 5, and being bitten the back wound by hornet can be red and swollen at once, and feels burning pain, can the causing death when serious.Hornet has simple social organization, honeybee arranged after, drone and worker bee, he usually builds hanging of papery honeycomb bell or stratiform, in the above collective livelihood.Hornet belongs to Hymenoptera Vespoidea class insect, and is very responsive to air quality, makes a living with the insect that eats on the flowers, plants and trees.Because the green plants of city constantly increases, damage by disease and insect is also increasing, and hornet just begins from the rural area to migrate toward the city, seeks food in the city.Temperature is higher, and air ratio humidity also is the key factor of hornet breeding growth.People have a kind of fear to hornet, and are less to catching and killing of hornet, also are one of reasons of increasing of hornet.

News report is constantly arranged in the recent period, and hornet has begun to have disturbed some people's operate as normal and life, even report is arranged because hornet attack/revenge causing death.Hornet has very strong toxicity, in a single day the people has made it angry because of carelessness, and its can colony attack the mankind, so danger close.Wherein ink chest wasp toxicity is very strong, and its toxicity is equivalent to more than ten honeybee.And different with common honeybee, after ink chest wasp was bitten the people, telson did not fall, can be not dead yet, can also continue to attack.If violent the attack, its toxicity can be poisoned a head of cattle with poison fully.Hornet is very clever, and major part is made on the cliffside tall trees branch point when doing nest, or city house two or three building canopy central authorities, and the mankind want to remove its just unusual difficulty like this.Once there was report fire brigade to set out to destroy hornet's nest again and again, even employed the strength of PLA.Because the restriction of hornet's nest position, only can be destroyed by fire brigade less than 30% hornet's nest.

The main method and the facility that destroy hornet's nest at present comprise:

1, giant.Fire brigade uses the giant of fire extinguishing usefulness, utilizes current at a high speed to destroy hornet's nest.

2, flame thrower.The flame that utilizes flame thrower to eject, high temperature burns hornet's nest.

3, directly extract.Directly extract hornet's nest by the personnel that worn the protection clothes.

4, sootiness.Utilize dense smoke that hornet is smoked away or smoked dead, remove the threat of hornet's nest.

5, medicine.By spraying medicine, poison hornet with poison, thereby destroy harmful hornet's nest.

There are a lot of drawbacks in the method for the destruction hornet's nest that these are traditional, and for example: limited to suitable environment, there have a lot of local people to be difficult to be approaching, perhaps can not use flame or High-Pressure Water, perhaps brings environmental pollution when destroying hornet's nest.And incorrect destruction method may cause the active attack of hornet to people, brings how unnecessary economic loss and personnel injury.Manual removal's honeycomb, the outer honeybee of nest still exists, and can not thoroughly kill the peak worm.

Microwave is meant that frequency is the electromagnetic wave of 300MHz to 300GHz.Microwave has a lot of application as a kind of carrier that transmits signal in the communications field, especially is widely used in wireless communication technology.In addition, microwave also can be used as a kind of energy carrier, in industry such as chemical industry, pharmacy, food more application is arranged also.Household microwave oven is the example that microwave heating technique is used.
