查询词典 carcinogenic substance

The antimicrobial test and researched was done on wide distillation of different solvents on Terpenoid, polarity separation of ethanol distillable substance, thin layer chromatography of different polarities and distillation of amylase. The results showed that the active substance distilled by 95% ethanol and V methanol: toluene=3:1 had stronger antimicrobial activity on Agaricus blazei Murrill. The antimicrobial activity of ethyl acetate was stronger than wide distilling substance with ethanol, but the water part has not antimicrobial effect. Two straps of ethyl acetate phase（Rf0.57、Rf0.63）(0.1g/ml)had stronger antimicrobial activity on Agaricus blazei Murrill, the antimicrobial zone on Pseudomonas was 19.3mm. The bacteriostatic activity of chromatography strap of water phase was rather weaker, the water solution (0.5g/g) of amylase had better effect on pathogenic fungus of Agaricus blazei Murrill, its antimicrobial zone on Aspergillus niger, Citrinin, Trichoderma viride were 10.8 mm, 7.9 mm, 5.3 mm.

As to the doctrine called the Real Presence,[22] the council condemns: those who, denying that Jesus Christ, God and Man, is truly, really, substantially present in the sacrament of the Holy Eucharist, hold instead that He is only present as in a sign or image or manifestation of power; those who say that the substance of the bread and the wine remains along with the body and blood of Christ, denying that marvellous and unique changing of the whole substance of the bread into the Body and the whole substance of the wine into Blood, while the appearance of bread and wine still remain--the change which the Catholic Church most suitably calls Transubstantiation; those who say that the Body and Blood of Christ is not there following upon the consecration, but only while the sacrament is in use, while it is being received, that is to say, but not before this or after this, and that in what is left over of the consecrated hosts or particles after communion has been administered, the true Body of the Lord does not remain; who say that the main fruit, or the sole fruit, of this sacrament is the forgiveness of sins; or that Christ the only begotten son of God is not to be adored in this sacrament with the externals of the reverence called latria,[23] and that those who do so adore Him in this sacrament are idolaters; that Christ is shown forth in this sacrament to be received in a spiritual manner, and not also sacramentally and really; that only faith is sufficient preparation for receiving this most holy sacrament.

至於所谓的理论的真实临在， [ 22 ]安理会谴责：这些谁，否认耶稣基督，上帝和人类，这是真正的，真的，大大目前在圣圣体圣事，持有相反，他只是本作为一个标志或形象或表现的权力；谁说，这些实质的面包和酒仍然随著身体和基督的血，不可否认，神奇和独特改变整个实质面包进入人体和整个物质的酒血，而出现的面包和葡萄酒仍然-改变了天主教会最适当的要求Transubstantiation ；谁说，那些身体和血液基督是不存在的神圣以下，但只有同时圣礼正在使用中，虽然它正在收到，这就是说，但在此之前或之后这本，在什麼是遗留下来的在神圣的主机或颗粒后共融已管理，真正的机构上帝不会留，谁说，主要水果，或唯一的水果，这种圣礼是宽恕的罪过；或基督唯一的独生子上帝是不喜欢在这圣礼与外部的崇敬所谓latria ， [ 23 ] ，这些谁做崇拜他的这一圣礼是拜偶像；基督显示本条圣礼收到在一个精神的方式，而不是还sacramentally真正；，只有信仰是足够的准备接受这个最神圣的圣体。

Again, if we remove from our empirical B6 concept of any object, corporeal or incorporeal, all properties which experience has taught us, we yet cannot take away that property through which the object is thought as substance or as inhering in a substance (although this concept of substance is more determinate than that of an object in general).

再则，如果我们从任何一个物质的或非物质的对象这个经验性的概念中除去经验所告诉我们的一切属性，我们仍然不能拿走对象通过它而被思维为实体或为依存于实体的那个属性（虽然实体这个概念比一般对象这个概念更为确定）。

Again, if we remove from our empirical concept of any object, corporeal or incorporeal, all properties which experience has taught us, we yet cannot take away that property through which the object is thought as substance or as inhering in a substance (although this concept of substance is more determinate than that of an object in general).

同样的，如果把所有经验属性从各种物质的和非物质的物体中取掉，仍然有不可拿走的属性，这种属性便是物体之所以被理解为物质并且是物质所固有的性质。

Substance dualists argue that the mind is an independently existing substance, while property dualists maintain that the mind is a jumble of independent properties that emerge from the brain and cannot be reduced to it, but that it is not a distinct substance.

In the process of building and using the mass concrete structures, because of the effect of out-side condition and themselves, some faults will form in the structure, these faults will effect the bearing capability and endurance Using nondestructive testing method to test the concrete"s quality and diagnose its healthy, which has the significant sense in assessing the safety stability and research of the administering diseasesThis dissertation mostly researched the testing methods in the mass concrete structure, discussed the principles, methods, features, sphere of application of the ultrasonic testing in the mass concrete structure with faults, used dynamic FEM to simulate the testing process, discussed when the concrete structure with cracks is under the effect of the pulse, how the elastic waves propagate and what are their changing feature, Researched the principles of the first-arriving waves" phase when the cracks" depths are not same, obtained the relation between the inversion point and the cracks" depth, which has the direction sense in the application of projects,The second part of this dissertation is CT , which used the ultrasonic wave running through the tested-substance to get arriving-time of the ultrasonic wave, then inverse the image This dissertation drawed one CT program which can well present the different little cells ultrasonic wave velocity profiles of the substance, thereby to diagnose the quality of the part of the tested-substance, CT has the better using foreground..

在混凝土结构的施工及使用过程中，由于受其自身及外界各种因素的影响，常常会产生一些缺陷，对结构物的承载能力和耐久性造成严重影响，采用无损检测技术进行质量检测和健康诊断，这对混凝土结构开展安全、稳定性评估以及病害隐患治理研究具有重要意义。本论文主要针对大体积混凝土结构缺陷的检测方法展开研究工作，重点讨论了超声波法检测混凝土结构裂缝的基本原理和方法及其特点、适用范围，运用动力有限元数值模拟其检测过程，探讨了有裂缝缺陷的混凝土结构在脉冲荷载作用下弹性波的传播及其变化特征，研究了不同裂缝深度下首波相位变化规律，得出了反转临界点与裂缝深度之间的关系，这对实际工程应用具有指导意义。声波CT是一种新的无损检测技术，它是利用声波穿透被检测体获取声波接收时间，来进行计算机反演成像的技术。本文利用直射线法编制了层析成像程序，能较好地呈现被检测物体各微小单元的声波速度分布图像，从而对检测体的质量状况作出诊断评估，具有较好的应用发展前景。
