To date, Ashford Formula has been specified and used to densify, seal and harden over 2 1/2 billion square feet (2,500,000,000) of industrial concrete surfaces, an area equivalent to a 3-foot wide concrete band circling the earth 6 times.

迄今为止，A/F被指定用于固化、密封和硬化工业混凝土表面超过2.5亿平方英尺，相当于一块3英尺宽的混凝土样快绕地球6圈。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc., under the action of which pyrogenic rocks, volcanic complex, aqueous rocks, sedimentary rocks etc., come into being, some of which exist in a stage of symbiosis, the main cause of the absence of pure rocks in nature, wherein lies the reason for the need of separation technology and apparatus, namely, ore-dressing devices and equipment, so far impotent to meet the requirements of metallurgical industry the scientists make every endeavor to elevate to a new high by laser separation.

矿石中天然固有的杂质严重影响其后来的质量。矿石的形成是地质变迁的结果，包括地壳运动，火山爆发，沉积作用，冰河作用和风化等等，在这些作用下，生成了火成岩，火山杂岩，水成岩和沉积岩等，一些矿石是由于这些作用共同形成的，这就是自然界中没有纯净矿石的原因。由于这些原因的存在，需要用分离技术和器械，也就是矿石加工设备对矿石进行的分割，迄今为止这些矿石加工设备已经不能够满足冶金工业的需要，科学家们力图用激光把冶金工业提高到一个新的水平。

没有什么比矿石形成之前就存在的杂质对矿石品质的影响更为重大。矿石是火成岩、火山群、水成岩、沉积岩等成形时，在包括地壳运动、火山爆发、沉积、冰蚀、风化等地质变化的作用下而形成的。而有些地质变化在一个发展阶段中存在共生现象。自然界无杂质岩石缺乏的主要原因在于需要分离技术和设备来完成，即：需要选矿设备和装置。而迄今为止，这些设备还难以适应冶金业的需要，虽然科学家们尽一切努力用激光分离技术将冶金业提高到一个新的高度。

Dimeric structure and several signaling pathways have thus far been proved to be closely correlated with the activation of c-Kit.

迄今为止，二聚化结构及磷酯酰肌醇3′-激酶（PI3K）、JAK-STAT等十几条激酶介导的信号通路被陆续证实与c-Kit的活化密切相关，而针对抑制c-Kit活化设计的靶向药物也陆续投入应用，与特异性的单克隆抗体一起在临床相关肿瘤的诊断及治疗等方面起到了关键性的作用。

The first half of the chapter begins with the introduction of three common viewpoints over the two kinds of theories, followed by deep investigation and description of some biased nature in them, then comes up with the conclusion that we must draw a clear distinction between what was said by Marx himself and what has long been accepted as dogmatical statements. The later half of chapter introduces various understandings to the theory of three social orders evoked by the discussion of economic social formation, points out the drawbacks of and the author"s disproval to the idea that economic social formation only exists in a definite historical period. This chapter is to deepen the understanding of Marx" theory of three social orders through the discussion of the other two important theories related to it.

首先介绍了迄今为止在&三形态说&和&五形态说&的讨论中出现的三种基本观点，并分别对这些观点加以反思，通过反思指出了这几种观点中存在的一些偏颇之处，提出了在讨论三大社会形态理论和五种社会形态理论的相互关系时要对马克思本人的&五形态说&和传统的教条化的&五形态说&加以明确的区分；接着介绍了在讨论&经济的社会形态&这一范畴时所引发的对三大社会形态理论的不同理解，指出了把&经济的社会形态&理解为一种特定历史阶段的社会形态类型所产生的问题，反对把&经济的社会形态&理解为一种特定历史阶段的社会形态类型。

From this point of view, the writings about the history of aesthetics might be put into two disrelated categories: one is the'intangible or metaphysical'history of aesthetic ideas, such as Chinese Aesthetic History and the Outline of Chinese Aesthetic History in many different versions and another is the'tangible or physical'history of aesthetic artifacts, such as Chinese porcelain, Chinese calligraphy and brush drawings and Chinese bronze utensils in various versions.

以此观之，国内迄今为止的美学史著作，似呈&道&、&器&分流的两种形态：一种是&形而上&的审美思想史，如诸种版本的《中国美学史》、《中国美学史大纲》等；另一种是&形而下&的审美物态史，像诸多版本的《中国陶瓷》、《中国书画》、《中国青铜器》等。

The results showed that 1,5-naphthalene disulfonic acid could be degradated effectively by the catalytic supercritical water oxidation process,the removal rate of COD reached 98% or even above;the removal rate of COD increased with the increasing of temperature and residence time,the orders of catalytic oxidation degradation reaction of 1,5-naphthalene disulfonic acid to COD and oxygen in supereritieal water were 0.89 and 0.28 respectively,and the activation energy was 56.8 kJ/mol.

Ding等[3]研究了NH3在MnO2/CeO2催化剂作用下在超临界水中的降解情况；Savage[4]简述了在超临界水中以CARULIFE 150、TiO2、MnO2、CuO为催化剂，对苯酚进行了超临界水氧化机理研究情况，但迄今为止涉及催化超临界水氧化的反应动力学的研究还不多。萘系有机污染物是印染

Gh:生长激素: Dori, I' trialling Superspeed and it is faultless so far.

吉通，我试用超这是迄今为止无懈可击。

However, when using this method, the interlamellar region is easily stuffed with the metal oxides, leading to a dramatical decrease in surface area and pore volume.

但迄今为止此方面的研究并不多见，主要原因是在金属负载过程中容易堵塞层柱材料的孔道。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
