英文簡介
Polyepoxysuccinic Acid (PESA)
Molecular Formula: HO(C4H2O5M2)n Molecular weight: 400-1500
Properties:
PESA is a multivariate scale and corrosion inhibitor with non-phosphor and non-nitrogen, it has good scale inhibition and dispersion for calcium carbonate, calcium sulfate, calcium fluoride and silica scale, with effects better than that of ordinary organophosphines. When built with organophosphates, the synergism effects are obvious.
PESA has good biodegradation properties, it can be widely used in circulating cool water system in situation of high alkaline, high hardness and high pH value. PESA can be operated under high concentration index. PESA has good synergism with chlorine and other Water Treatment Chemicals.

簡稱介紹
PESA（無源相控陣雷達的簡稱）
PESA：Passive Electronically Scanned Array，無源相控陣雷達（又稱被動相控陣雷達）的簡稱，區別於有源相控陣雷達（AESA：Active Electronically Scanned Array），它僅有一個中央發射機和一個接收機，發射機產生的高頻能量經計算機自動分配給天線陣的各個輻射器，目標反射信號經接收機統一放大（這一點與普通雷達區別不大）。
