2. 不持续就爆炸. 无法持续只能爆炸.
3. blast => clast: c‐开,炸开了岩石成碎屑.
4. 由b到c, 这是字母顺序关联性,因此clast可以看成是blast爆炸后的结果.            
                        
            
                        
            
                
- blast (n.)
- Old English blæst "blowing, breeze, puff of wind," from Proto-Germanic *bles- (cognates: Old Norse blastr, Old High German blast "a blowing, blast," German blasen, Gothic blesan "to blow"), from PIE *bhle- "to blow," probably a variant of root *bhel- (2) "to blow, inflate, swell" (see bole).
 
 
 Meaning "explosion" is from 1630s; that of "noisy party, good time" is from 1953, American English slang. Sense of "strong current of air for iron-smelting" (1690s) led to blast furnace and transferred sense in full blast "the extreme" (1839). Blast was the usual word for "a smoke of tobacco" c. 1600.
- blast (v.)
- Old English blæstan "to blow, belch forth," from the root of blast (n.). Since 16c., often "to breathe on balefully." Meaning "to blow up by explosion" is from 1758. Related: Blasted; blasting. Blast off (n.) is attested from 1950.
