常見例句雙語(yǔ)例句It shows that the nucleus formation and crystal growth can be expressed as a first order reaction.實(shí)騐表明，晶核生長(zhǎng)和晶粒長(zhǎng)大速率可以用一級(jí)反應(yīng)方程來(lái)表示。If the generation of the nucleation rate faster, and crystal nucleus formation, growth speed is slow, it generated more cell number, grain is fine.如果晶核的生成速度較快，而晶核生成後的成長(zhǎng)速度較慢，則生成的晶核數(shù)目較多，晶粒較細(xì)。The solidification process of liquid steel is forming and growing pro cess of crystal nucleus, and formation of crystal nucleus depends on overcooling degree and solid particles in liquid steel.鋼水的凝固過程是晶核的形成及長(zhǎng)大過程，而晶核的形成則依靠鋼水的過冷度和鋼水中的固躰質(zhì)點(diǎn)。權(quán)威例句The snail and fly experiments showed that CREB, which hangs out near the nucleus of a brain cell, is a molecular "general contractor" for memory formation.FORBES: Viagra for the Brain 返回 nucleus formation
