由于這種復(fù)雜度，一個(gè)溶劑分子通常由一個(gè)稱為探針的球來近似;探針的大小由溶劑分子的大小決定。 - The chelation ability made ac - hac act as a protection layer on the surface of cds nanoparticles , which reduced surface states and improved the band edge emission . 3
這是因?yàn)榫郾┧?丙烯酸羥丙酯在一定程度上能夠修飾cds納米粒子表面，減少表面缺陷，提高納米粒子的帶隙發(fā)光。 - The effects of meor include as follows : being favorable to oil - gas percolation , changing wettability of rocks , improving hydrocarbon migration , reducing surface tension of emulsified oil , decreasing crude viscosity and improving sweep efficiency , etc
采油微生物具有自身的優(yōu)勢，有利于油氣滲流及提高采收率，尤其是微生物能改變巖石潤濕性、改善油氣運(yùn)移、乳化原油降低表面張力，微生物及代謝產(chǎn)物還對原油具有降粘作用，對地層水產(chǎn)生有利影響，提高波及系數(shù)。 - It's difficult to find reducing surface in a sentence. 用reducing surface造句挺難的
- Based on the theory of shrinkage , capillary force theory , the influence of road concrete additives in common use on surface tension of water is studied , and the results show that the influence of water reducer is very small whereas shrinkage - reducing agent and air entrainer can reduce surface tension of solution significantly . the relation between surface tension and additive dosage are non - linear relation . each additive has an obvious critical micelle concentration ( cmc )
從混凝土收縮的基本理論? ?毛細(xì)管張力理論出發(fā),通過道路混凝土外加劑對水的表面張力的影響研究發(fā)現(xiàn),減水劑對水的表面張力的影響很小,而減縮劑和引氣劑可以大幅度降低溶液的表面張力,溶液的表面張力隨外加劑的摻量呈非線性形式降低,而且都存在臨界膠束濃度。 - Typical temperature is 800 - 1000 in cvd diamond process , while the high temperature limits its application in optical window and coating such as gaas , zns etc . low temperature can not only make diamond crystal nucleus finer , reduce surface roughness of diamond films and lessen light dispersion , but also eliminate thermal stress
化學(xué)氣相沉積金剛石膜過程中，襯底的典型溫度為800 1000 ，這么高的溫度限制了其作為gaas 、 zns等低熔點(diǎn)光學(xué)材料窗口和涂層的應(yīng)用。低溫沉積金剛石膜不僅可以使晶粒細(xì)化，降低表面粗糙度，減小光的散射作用，而且可以消除熱應(yīng)力。 - Construction of flat tunnel of large span at extra - shallow depth must be conducted on the principle that advance grouting should be strictly performed before excavation and length of pull at one time should be short , together with reinforced support , immediate closing and constant monitoring and surveying . that preceding pilot tunnels , large - volume excavation divided into small ones , excavation of flank before that of center , upper before lower , arch before wall etc is a good method which could effectively reduce surface subsidence and its adverse effect on adjacent buildings , in addition , some other measures are also taken to lessen blast - induced vibration in the ground and surrounding structures . in a word , all means and steps mentioned above have already proved effective and practicable in practice
軟弱大跨超淺埋扁平隧道必須按“管超前，嚴(yán)注漿，多分部、短開挖、強(qiáng)支護(hù)、快封閉，勤量測”的施工原則進(jìn)行施工，采用“眼鏡超前，化大為小，先側(cè)后中，先上后下，先拱后墻”的施工方法控制地表沉降和對周邊建筑物的影響；采用“多分部，化大為小，短進(jìn)尺，密布眼，弱裝藥，設(shè)減振槽” ，控制爆破振動(dòng)，經(jīng)過實(shí)踐證明，這些方法都是行之有效的。 - Take removes in the water to have the slight pollutant as the goal activated charcoal surface modified direction is : the reduced surface lactone base and the carboxyl group and so on contain the oxygen functional group the content , increase activated charcoal surface sparse river characterthe modified activated charcoal in has a drink together in the water used adsorption treating processes , a weak basicity environment is good
我們研究了以濃硝酸、次氯酸和氨水去除水中三氯甲烷為主要目標(biāo)表面改性活性炭吸附處理技術(shù)。立意方向?yàn)?減少表面內(nèi)酯基及羧基等含氧官能團(tuán)的含量,增加活性炭表面的疏水性。
