secondary cracking
解釋
二次裂化-
The gas generation of low mature source rocks has been simulated in the open system and close system respectively. the models of primary cracking gas ( gas from kerogen ) and secondary cracking gas ( gas from oil ) have been established. the ro value of primary cracking gas generation peak is ranged from 1. 0 % to 1. 5 %. the ro value of secondary gas generation peak is ranged from 1. 5 % to 2. 5 %
對低成熟（部分為成熟）的烴源巖在開放和密閉體系下的生氣熱模擬實驗研究建立了熱解氣和油裂解氣的生氣模式，熱解氣的生氣高峰在ro = 1 . 0 ? 1 . 5 ，油裂解氣生氣高峰是在ro = 1 . 5 ? 2 . 5之間，從熱解氣和油裂解氣的相對含量來看熱解氣占總生氣量的21 ，油裂解氣可能佔79 ，油裂解氣產率為620m ~ 3噸 -
Tar content in the gas was influenced by the gasification conditions, such as the gasification temperature, residence time of feedstock in the gasifier and the type of feedstock, which can help us to investigate the mechanism of tar production in gasification process. catalytic cracking of tar was performed in a downstream secondary fixed - bed cracker with dolomite, limestone and alumina brick as catalysts. by comparison, thermal cracking of tar was also performed with silica carbide
在固定床二級催化裂化反應器上，實驗了白雲石、石灰石、高鋁磚等幾種催化劑作用下的焦油催化裂化過程以及炭化硅作用下的熱裂化過程，並對裂化溫度（ 650 950 ） 、氣相停留時間（ 0 . 5 1s ）和催化劑類型等過程參數對焦油轉化效果和熱解煤氣的影響進行了分析，對各種催化劑材料的性能進行了比較，力爭開發出可適用於工業化生物質氣化系統的焦油催化裂化技術。 -
For example still the arguments exist about the cracking controlling, the behavior of secondary moment and the re - distribution of internal forces, especially for the moment, of the prestressed concrete continues beam or frame
例如在對預應力混凝土連續梁和框架的裂縫控制、次彎矩以及結構的塑性內力重分佈尤其是彎矩重分佈這些問題上還存在著廣泛的爭論。 -
The beams under secondary loading ( namely the preloading was not removed ) are firstly studied in this dissertation, and the ultimate strength, stiffness, and the distribution of cracks of the beams strengthened with ferrocement have been analyzed. mid - span deflection, crack width and strains of steel were measured during the course of the test, and performances of the beams are compared and assessed with particular emphasis on cracking behavior, mid - span deflection, ultimate strength capacity, the modes of failure and so on
本文首次對二次受力（初始荷載不卸除）試件進行了加固試驗研究，試驗中測量了試件的極限荷載、混凝土應變、鋼筋應變及鋼筋網應變等，對比了加固與未加固構件的裂縫開展、跨中撓度以及極限荷載情況，並研究了用該方法加固的梁在各種受力情況下可能產生的破壞形式等。 -
The quantity of secondary cracking gas is up to 79 percentage of the total gas generated. the comprehensive correlation between gas and source rock shows that natural gas in the north, west and south part of the center gas fields mainly come from lower paleozoic source rock, the attribution ratio of lower paleozoic source rock is up to 60 - 70 %. in the other part, natural gas is mainly from upper paleozoic souce rock, its attribution ratio is up to 70 %
採用氣?烴源巖直接和動態對比的研究思路對鄂爾多斯盆地中部氣田氣源進行了多項地球化學參數綜合對比研究，進一步證明中部氣田氣源具有混源特徵，但是，在不同區塊上、下古生界天然氣混合程度不同，在中部氣田的北部、西部和南部天然氣主要以下古生界來源為主的混合氣，而中部氣田的東部則主要以上古生界來源為主的混合氣。
