Реферат: DESRIPTION AND DEFINITIONS

The Materials and Methods section describes your experimental procedures. It is a straightforward recounting of your approach.This section should not be too lengthy; some information may be of lesser interest and can be de-emphasized by using smaller print.

Experimental conditions are briefly but precisely described. Novel methods should be described in detail, but published methods should merely be cited byappropriate references to both the original and any published modifications.

Thus, this section should deal with four main topics:

1. Equipment and materials used

2. Experimental design

3. Observations made

4. Methods of analysis used, statistical (and chemical if required) data

Verbs in this section are generally written in the past tense. Use of the passive voice is also acceptable, especially as a means of placing emphasis. For instance,

Enzyme Awas purchased from Sigma

isbetter than

We purchased enzyme Afrom Sigma

because emphasis here should be on the material, not the authors.
