The substance of thinking quality is the difference expression of the individual thinking ability , and also is the character difference that puts up during the time when activity of thinking occurs and develops 思維品質(zhì)的實(shí)質(zhì)是個(gè)體思維能力的差異性表現(xiàn),是在思維活動發(fā)生和發(fā)展的過程中表現(xiàn)出來的個(gè)性差異。
In accordance with the water tunnel that liner have cooling pipe , thermal insulation temperature rise model adopt difference expression during its through or not water phase , and optimization back analysis of parameters is carried out 針對本工程引水洞襯砌內(nèi)布置有冷卻水管,對絕熱溫升模型在通水前后采用了不同的表達(dá)式,并分別對其進(jìn)行了優(yōu)化反演分析。
When discreting the sonic and elastic analytic equation , the paper shows different finite - difference forms of sonic and center finite - difference form of elastic by detailed deriving in different situation . at the same time , the paper discusses the finite - difference ' s stability and the boundary conditon of gridding region , then lists the final sonic and elastic finite - difference expression which can realize forward modeling and inverse in computer by programming 在對聲波與彈性波解析表達(dá)式進(jìn)行離散時(shí),論文按不同情況進(jìn)行了詳細(xì)的推導(dǎo),由此得到聲波方程各種不同的差分格式和彈性波的中心差分格式,在此基礎(chǔ)上還對差分方程穩(wěn)定性條件與網(wǎng)格區(qū)域邊界處理進(jìn)行了討論,最后得到完整的能在計(jì)算機(jī)上進(jìn)行正反演編程運(yùn)算的聲波與彈性波有限差分格式。
