With the development of the global economy, energy consumption continues to increase, and the discharge of acidic pollutants is increasing. The problem of acid rain is becoming increasingly serious. People have already controlled the discharge of acidic pollutants, but the phenomenon of acid rain still exists, and the harm caused to humans is also increasing day by day. Through the determination of precipitation and wind speed in the west of Jiangmen City, we have come to understand how weather influences rainfall. The wind anemometer is a scientific instrument we need to use to record changes in the air at any time. Quartz crucible Acrylic Weld BOPS heat shrinkable film Carbon fiber helmet are special material. Their grinding processing at present are manual, the force imposing on the Grinder is not consistent, most are based on technician experience or technique. Our Force Control System can flexible control the force imposing on the grinder, quick response to the surface changing, and instant adjusting the force on the grinder.

According to relevant data, the maximum acidity weakening occurred on June 19, 2006. The pH value increased by 1.10. The precipitation continued for 2 days. The wind direction changed to SW on the second day. The direction of the windward direction was underdeveloped. The 1.1-m/s SSW wind has brought clean and humid air over the South China Sea into the inland. Together with the rainfall of 83.4mm on the day, the day's sulfur dioxide concentration decreased by 0.015mg/L from the previous day. The next largest value appeared on August 22, 2005. The pH value increased by 1.08. The precipitation lasted for 7 days. It was the longest continuous precipitation period in three years. The acidity of the precipitation fluctuates greatly; the wind speed is in the 2nd to 6th. Days are close to 0, and the frequency of static wind is mainly characterized by the emission of local acidic pollutants. The temperature and pressure increase day by day, and the airflow is mainly updraft. The continuous precipitation in the first 4 days has strong scrubbing of the near-ground air, making the air clean, and the precipitation on the 5th day suddenly increases to 33.7mm. The average wind speed was 0 on the day, and there was limited supplementation of surrounding acidic materials, and the precipitation acidity was significantly reduced. However, the precipitation on the 6th day was significantly reduced to only 4.1 mm. The temperature and humidity of the S-directional wind brought acidic pollutants to add, and the near-surface air humidity was added. Large, strong chemical reactions, sudden increase in precipitation acidity 0.81, from the continuous precipitation analysis over the past three years, we can see that the wind speed of the E to SE, S and SW azimuth wind, especially the typhoon, brought about the formation of clean air near the surface of the ocean The regimen will weaken the precipitation acidity. The SSE azimuth wind with smaller wind speed transports the wind upstream to the industrial pollution air mass; the ENE azimuth wind with high wind speed transports the wind upstream to the industrial pollution air mass and chemically reacts with the near-surface air mass with high humidity along the road. Acidic pollutants are enriched, gradually increasing the acidity of precipitation. In addition, in meteorological measurements, we often use small weather stations because this instrument can measure up to 11 parameters and has comprehensiveness.
Weather is a big environment that we live in every day. For example, every day's weather forecast is cloudy, sunny, rainy, windy, etc., all of which we can feel everyday, but in the meteorological testing department, we need formal instruments. Such as field microclimate automatic observer, wind direction wind speed monitor, etc., for the specific detection of wind speed, wind direction or temperature, humidity, light intensity, dew point and other parameters.
