Test method for time of setting of concrete mixtures by penetration resistance 用耐滲透性測(cè)試混凝土混合物固結(jié)時(shí)間的試驗(yàn)方法
Standard test method for time of setting of concrete mixtures by penetration resistance 由抗穿透性測(cè)定混凝土混合料凝固時(shí)間的標(biāo)準(zhǔn)試驗(yàn)方法
Abnormal setting of concrete and improper control of curing condition is two important factors affecting the quality of concrete 混凝土不正常凝結(jié)和養(yǎng)護(hù)條件控制不力是影響混凝土工程質(zhì)量的兩個(gè)重要方面。
Plan to probe out a set of concrete tactics of expressing metaphor thinking of architecture design , detaily explained the architecture metaphor tactics combining instance 擬從中探索出一套表達(dá)建筑隱喻思維的具體手法,并結(jié)合實(shí)例對(duì)建筑創(chuàng)作中的隱喻手法進(jìn)行了詳細(xì)地闡述。
Most of the timed automata reachability analysis algorithms in the literature explore the state spaces by enumeration of symbolic states , which use time constraints to represent a set of concrete states 但是,隨著系統(tǒng)規(guī)模的擴(kuò)展,狀態(tài)空間的大小呈現(xiàn)爆炸性的增長(zhǎng),往往超出了當(dāng)前計(jì)算機(jī)的能力極限。這被稱為“狀態(tài)空間爆炸問題” 。
