What does Daikin mean?

Question 1: What do you mean by rushing to the east when rushing to the rabbit? Rushing rabbits: affecting people who belong to rabbits. Dongsha: It's not good to go to the East. Rabbit: Four or five in the morning is not good. Xun Kong: The combination of trunk and branch in Richen is ten days' trunk and ten earth branches, so there must be two earth branches without trunk to match within ten days. So it's called iFLYTEK (the answer comes from Baidu). Dajin: Literally means great progress and increase. Tang Ming: Feng Shui master said that the atmosphere in front of the cave was gathered from his own place. Jin Lu: Pay increase.

Question 2: What do you mean by "Shi Mao Daikin"? Shi Mao Duckin: I moved in between 5 and 7 in the morning.

Shi Mao, sunrise, also known as the beginning of the day, dawn, sunrise, etc. Refers to the time when the sun just appeared and Ran Ran first rose. (5 am to 7 am). The moon, also known as the Jade Rabbit, is still in the sky during this time.

Question 3: What does Lunar New Year mean? Nearly 30 days long, 29 days short.

Question 4: What do you mean if you make great progress, you won't see the sun? Baidu (the world's largest Chinese search engine)

Question 5: What do you mean? Luck means happiness.

Question 6: What does it mean to be tall? The exact "height" of Mount Everest will not be announced until August this year.

The so-called height is actually relative. The height of Mount Everest is relative to the sea level. In China, the average sea level of the Yellow Sea measured by Qingdao Tide Station is zero, because the surveyors already know the precise elevation of Lasi County relative to this point, so the height of Mount Everest only needs to be measured from Lasi. In the first half of the survey, the traditional accurate leveling method is still used, that is, a datum point is erected every tens of meters, the height difference is measured with a level, and the height difference is accumulated station by station to calculate the accurate figure, so that it is counted until the foot of Mount Everest.

Since the foot of Mount Everest, the surveyors have changed the measurement method. They chose six relatively flat measuring points between 5200 meters and 6300 meters above sea level, which is convenient for setting up instruments and seeing the summit of Mount Everest.

After the summit team successfully erected the beacon at the summit, the surveyors of these six measuring points used laser rangefinders to send lasers to the summit. After being reflected by the prism on the summit beacon, the straight-line distance and horizontal elevation angle between the measuring points and the summit can be measured, and then the height difference between the summit of Mount Everest and these points can be calculated by using the pythagorean theorem in geometry and other basic principles. This survey method is called "trigonometric leveling", and the height of Mount Everest in China 1975 is 8848. 13m, which is the adopted method. This is the most widely used one in the world at present.

In order to make the height of Mount Everest measured this year more accurate, while using this method, the surveyors also adopted the modern GPS satellite measurement method.

Chen Xianjun, senior engineer of Geodesy Department of National Basic Geographic Information Center, said: "GPS antenna can directly measure the coordinates of the summit by receiving satellite data. At the same time, this coordinate itself contains the amount of elevation. This accuracy is compared with the classical method as a new technical means to ensure the accuracy of our measurement of the altitude of Mount Everest. "

Both of these methods can calculate the distance from the summit of Mount Everest to the zero altitude of China, but the thick snow on the summit of Mount Everest is countless. Accurate measurement of snow depth is an important part to improve the measurement accuracy this time. 1975, the altimeter used a pole inserted in the fragrant snow to measure the depth of ice and snow. This method is prone to errors due to strength, angle, frozen layer and other reasons. This year, China took radar detectors to measure the depth of snow and ice at the peak for the first time, and the obtained data was more accurate.

No matter which measurement method is adopted, there will always be errors in the measured height due to temperature, air pressure, gravity and other reasons, and it is necessary to eliminate the errors through complicated calculations. This calculation process will probably take more than a month, and then the data will be reviewed, so the exact "height" of Mount Everest will not be announced until August this year at the earliest.

Relevant research shows that Mount Qomolangma, the world's highest peak, is still full of vitality, moving tens of millimeters horizontally to the north every year and "growing up" by nearly 10 mm.

1975, the high activity of Mount Everest was measured for the first time in China, and the result was 85438+03m.

Question 7: What does "big import and big export" mean in processing trade? "Big import and export" is the most prominent feature of traditional processing trade, that is, the big export of processing trade is based on big import. From 199 1 to 1997, the total import of processing trade accounts for more than 70% of the total export of processing trade, and even reaches more than 80% in some years.

Question 8: What do you mean by a book that has made great progress? The meaning of calligraphy.

Calligraphy has made great progress.

Question 9: What do you mean by the treasury, special fortune and great progress in eight-character fortune telling? The ugliness of Chen Xu is not the national treasury, and those who win gold think that wood is not the national treasury. Sitting in an official position is a special job, such as Jain and Yi Mao.

Question 10: What does three-in-one mean? It means trinity, and the three attributes in the five elements mean merging into one attribute. When you meet something you like in the five elements, you will be smooth.
