active material

基本解釋

Conducting tubes are used in wires and electrodes but semiconducting tubes are the active material for transistors or solar cells.
導(dǎo)電管用于電線和電極中，用于晶體管或太陽(yáng)能電池中的半導(dǎo)體管采用了活性材料。
Once the lithium ions are free, they move only in and out of the active material, and the inactive material continues to play its stabilizing role.
一旦鋰離子是免費(fèi)的，他們只移動(dòng)進(jìn)出的活性物質(zhì)，不活躍的物質(zhì)繼續(xù)發(fā)揮穩(wěn)定作用。
The material has both active components, through which lithium ions move when the battery is charged or discharged, and inactive ones that help stabilize the active material and extend battery life.
該材料具有兩種有效成分，通過(guò)它移動(dòng)時(shí)的鋰離子電池充電或放電，這有助于穩(wěn)定活性物質(zhì)，延長(zhǎng)不活躍的電池壽命。

Conveyor belts carried long, wafer-thin strips of metal into printing-press-like rollers, which coated them with electrode-active material.

It focused narrowly on areas in and around active genes, ignoring the 98.5% of genomic material known as "junk DNA." This process pinpointed 25, 000 genetic landmarks called SNPS (single nucleotide polymorphisms, or "snips"), places where a single dna letter varies from one person to the next.

活性物質(zhì)
The utilization of lead acid battery active material is universally very low though its technology has reached the maturation. Especially, the utilization of positive active material is much worse.
雖然鉛酸電池的技術(shù)已經(jīng)比較成熟，但普遍存在活性物質(zhì)利用率比較低的問(wèn)題，特別是正極活性物質(zhì)的利用率更是不理想，正極的性能決定著整個(gè)電池的性能。
