| 请问:In the broadest sense, an instrument for chemical analysis converts a signal that is usually not directly detectable and understandable by man to a form that is.这句话有没有语法错误?最后的that is后面是不是省略了内容?如果是,省略了什么?如果没有省略怎么翻译?that is那儿搞不懂。 |

This text deals with most of the instrumental methods listed in Table 1-1, as well as with many of the most widely employed separation procedures. Little space is devoted to the classical methods, since their use is normally treated in elementary analytical courses. Table I-I suggests that the chemist faced with an analytical problem may have a bewildering array of methods from which to choose. The amount of time spent on the analytical work and the quality of the results are critically dependent on this choice. In arriving at a decision as to which method to choose, the chemist must take into account the complexity of the materi~ to be analyzed, the concentration of the species of interest, the number of samples to be analyzed, and the accuracy required. His choice will then depend upon a knowledge of the basic principles underlying the various methods available to him, and thus their strengths and limitations.(前) 一段的开头 In the broadest sense, an instrument for chemical analysis converts a signal that is usually not directly detectable and understandable by man to a form that is. Thus, an instrument can be viewed as a communication device between the system under study and the scientist.(求助段) 后面是另一部分内容。 Components of Instruments(后) Regardless of its complexity, an instrument generally contains nO more than four fundamental components. As shown schematically in Figure 1-1,these components are a signal generator, an input transducer or detector, a signal processor, and an output transducer or readout. A general description of these components follows. |
