First, the snow on the sunrise hillside is melting, and slowly revealing the yellow and black earth. The snow water moistens the soil and moistens the grass of last year. The grass roots that had been hibernating under the cover of snow came to life, and gradually pushed away the old grass and rotten leaves stubbornly and vigorously, and struggled to growGet up. At the same time, the seeds of plants and trees shaken down by the wind in previous autumn are also wrapped in wet soil, growing roots in the grass and fighting for their life.
The doors and Windows and wooden bed are really beautiful, flowers open on it, birds cry on it, butterflies dance on it, fish swim on it, and vegetables and crops and poultry, all fly and grow vividly on it, perhaps their whole life is for a good house and a good bed, so they have taken pains to carve wisdom, glory and lifelong dreams on it. Left to posterity.
Like to see the beautiful south bank of the grass green river, the cold winter in their laughter to escapeShun, is how tender a stem stem new green oh, in the stone cracks, on the soil, bravely straighten their thin waist, in the cold wind and rain, inch by inch to grow, a little bit of the embankment slope, the earth was buried, the blue sky breeze weaving people excited spring clothes.The prose poem "Jiangnan" is a beautiful article: the beauty is in the beautiful mood of poetry; The beauty lies in its beautiful and timeless words. The beauty of emotion and the beauty of language merge into the special style of this article. "South of the Yangtze River" is a beautiful picture of the south of the river, which is fascinating to read. With the title of "South of the Yangtze River", it is difficult to write up: so large south of the Yangtze River, can write sceneryToo much style, how to write, how to choose the Angle is quite a lot of consideration.
Love around us are single children, there is too much love but we ignore it, we sometimes sigh how unfair fate is, no parents as happy freedom, no parents childhood a group of small partners, no, too much do not, only too much nagging, too much preaching, suddenly when they are gone, I didn't know I was ready.
>500 words: Snow warm country rain, has never changed the cold hard brilliant snow. Knowledgeable people find him monotonousHe thinks he's unlucky too, doesn't he? Jiangnan snow, but moist beautiful to the; It was the still looming message of youth, the skin of a virile virgin. In the snow, there are red pearl camellia, white hidden green single petal plum blossom, dark yellow qing waxy plum blossom; There are cold green weeds under the snow.
1. The answer is yes! It's just not very likely, say a few missiles with a high probability of meeting a bird, and also say protectionThe measures of... The anti-air missile, which strikes the air target from the ground, will meet the bird obstacle when it is launched from the ground, so it uses the radio proximity warhead, which is triggered according to the magnetic field, sound field, static pressure field and electromagnetic field characteristics of the target, and the bird does not meet the trigger conditions.
2, if it is a cruise missile, because of long-term ultra-low flight, is taking into account the bird impact problem, the warhead is not in a column in the cruise stage, the target area is unlocked, there is a strict target optical matching identification system to ensure that it is exploded in the place of the explosion, airborne ground-to-ground guided weapons belong to the integrated use of the above two types.
3, It is the birds that inspired mankind and helped mankind realize the dream of flight. Hawk-eye and Missile tracking system The eagle can accurately identify animals on the ground at an altitude of thousands of meters, because of its special eye structure. Every human eye has a notch in the retina called the fovea. 4. Therefore, the warhead of the cruise missile is locked during flight, and it will not be unlocked until it is close to the attack target. In addition, the detonation method used by cruise missiles is generally not collision detonation, but radio or electromagnetic detonation. Which is to use the attack target to reflect electromagneticThe wave frequency is high or low to detonate.
5. The electronic frog eye can identify objects of certain shapes with the same accuracy as the real frog eye. The anti-jamming ability of radar is greatly improved after the electronic frog eye is installed in radar system. This radar system can quickly and accurately identify specific shapes of aircraft, ships and missiles. In particular, it can distinguish between real and fake missiles to prevent fake from being real. Electronic frog eyes are also widely used in airports and traffic arteries.
6, according to the principle that the cheek nest of the rattlesnake can feel the temperature change of 0.001 ° C, mankind invented the tracking and pursuit of the rattlesnake missile. HumansThey also designed frog rammers using the frog jumping principle. The "electronic police dog" has been made by humans to imitate the high sensitive sense of smell of police dogs. Scientists have created the world's first gas masks based on a wild boar's unique ability to detect poison through its nose.
I think that, at least with current technology, it is impossible to achieve this. Water can carry the boat, can also overturn the boat, in order to make money, the conscience of the people, but the people are good? I don't think so. The deceiver deceives himself.
We all know that the principle of wireless charging, wireless energy seems to be a new concept
