长期存在的

Both DO and ORP are used as fuzzy control parameters of SBR1 aerobic duration, which can maintain heterotrophs for organics removal and Nitrosomonas in different reactors and make TSSBR system operate stably and reliably.

将DO和ORP联合作为SBR1阶段好氧反应时间的模糊控制参数，可使去除有机物的异养菌和硝化菌存在于不同的反应器内，保证两段SBR系统长期稳定运行。

Based on current references about periclase expansion, it is considered that MgO con- tent limitation stipulated in the present national cement standard should be replaced by examining cement soundness with autoclave expansion test in order to guarantee quality of concrete engineering and to make full use of limestone resources.

所以直至今日仍有很多学者在为保证混凝土长期安定和合理使用资源两者之间探索新的路子。我国水泥标准在1977年修订时放宽了MgO规定，但它并不完全是建立在科学的，合理的基础上，其规定本身在实践中尚存在矛盾现象。

In the long history of the devolopment of Orientalism, there are always two apparently different attitudes towards Orient: one is contempt and enmity,that is uglify and demonize Orient;the other is appreciation and aspiration,that is beautify and poeticize Orient.

在东方学的长期发展过程中，始终存在着两种对东方表面上截然相反的态度：一种是对东方的轻蔑和仇视态度，表现为将东方丑化和妖魔化；另一种是欣赏和向往东方，表现为将其美化和诗意化。

Synchronizer in automobile is made up of carbon fiber strip, tach and adhesive, which is used at 180 in loog peried. Powerful torsinal strength in synchronizer operation request that the adhesive is heat-resisted structural.

汽车同步器由圆锥环与制动带粘接组成，要求可在180℃环境下长期使用，同步器在运转时存在强大的圆锥同步扭矩以及苛刻的温度环境均要求用于粘接制动带的胶粘剂必须是耐高温结构胶粘剂。

Visual responses of 80% tectal cells were reversibly blocked by NMDA antagonist CPP, and those of 20% cells by muscarinic antagonist atropine, suggesting that retinotectal pathway in toads may contain two groups of optic fibers that use glutamate and acetylcholine as transmitters, respectively.

视网膜-顶盖是视觉信息进入脑的第一站，但是对两栖类视网膜-顶盖投射所用递质却长期含混不清；另一方面，峡核是次级视觉中枢，与顶盖间存在着密切的神经联系，虽有实验对峡核-顶盖投射的突触连接性质进行了研究，但却未见峡核-顶盖投射所用递质方面的报道。

Different variabiles in economic system interact with each other. The long-term stability is analyzed on the basis of Gansu Province's GDP, total sum of expenditure, total sum of investment, and total sum of exports, and the thort=term fluctutation is analyzed on the basis of variables in ECM. Thus, the reality of Gansu Province's economy is revealed and corresponding countermeasures are put forward in a broad sense.

经济系统各变量之间相互制约、相互促进，以甘肃GDP、消费总额、投资总额和出口总额作为一个系统，检验该系统各变量之间是否存在协整关系，即研究系统各变量之间的&长期&稳定关系，进而基于ECM模型研究系统各变量的&短期&波动，揭示甘肃经济的本质特征，并提出相应的宏观经济政策建议。

It is clear that he rejected Transubstantiation; but what sort of presence he admitted would seem to have varied at different periods of his long career.
