2. Can someone explain the English abbreviations and their Chinese meanings. Its like MHz, GHz, and so on!

MHz: Megahertz, is a unit for measuring the frequency of electromagnetic waves, which can oscillate 3.4 million times per second. GHz: Gigahertz, also a unit for measuring the frequency of electromagnetic waves, capable of producing 1 billion oscillations per second. Other abbreviations include: GB: Gigabyte, which represents the unit of computer storage capacity. MB: Megabytes, also a unit that represents the storage capacity of a computer. TB: Gigabyte, representing a computer storage unit with larger storage capacity. LCD: Liquid Crystal Display LED: Light Emitting Diode HDMI: High Definition Chu Du Multimedia Interface USB: Universal Serial Bus VGA: Video Graphics Array CPU: Central Processing Unit RAM: Random Access Memory

3. PESA English Introduction

PESA is a unique radar system and also a water treatment chemical. The following is its English introduction: As a radar system: Definition: PESA stands for Passive Electronically Scanned Array radar, which features a single central transmitter and a receiver. Operation Principle: Unlike Active Electronically Scanned Array radars, PESA distributes highfrequency energy to each radiator of the antenna array automatically by a computer. The reflected signals from targets are amplified uniformly by the receiver, similar to the operation of conventional radars. As a water treatment chemical: Characteristics: PESA exhibits multivariate scale inhibition and corrosion inhibition properties. It is phosphorus and nitrogenfree, effectively inhibiting and dispersing scaleforming substance

s such as calcium carbonate, calcium sulfate, calcium fluoride, and silicates. When coexisting with common organic phosphates, it demonstrates significant synergistic effects. Biodegradability: PESA possesses good biodegradability and is suitable for use in highalkalinity, highhardness, and highpH circulating cooling water systems. It performs well even under highconcentration conditions. Synergy with Other Chemicals: PESA has synergistic properties with chlorine and other water treatment chemicals. Specifications: PESA appears as a colorless or translucent liquid with a solid content of at least 40.0%. Its density at 20 ° C is 1.28g/cm3, and the pH value of a 1% aqueous solution ranges from 9.0 to 12.0. Applications: PESA is widely used in oilfield water injection, crude oil dehydration, boilers, and circulating cooling water systems in industries such as steel, petrochemicals, power, and pharmaceuticals. It is also suitable for boiler water, circulating cooling water, seawater desalination, membrane separation systems, and detergent applications under conditions of high alkalinity, hardness, pH value, and concentration index. Packaging and Storage: PESA is typically packaged in plastic drums with a net weight of 250kg per drum, or IBC drums can be used as needed. It should be stored in a cool, dry room and has a shelf life of up to 10 months. Safety Precautions: Avoid contact with eyes and skin. If contact occurs, rinse immediately with water.Please note that the above introduction combines the definitions and applications of PESA in both radar systems and water treatment chemicals. In specific contexts, the relevant information should be selected and presented accordingly.
