expansion is called The simple continued fraction of x . It is customarily written x = [ a 0 ,a 1 , . . . ,a n , . ]. We call convergents of x the reduced fractions difined by: p 0 q 0 = a 0 , $$\frac{{{p}_{0}}}{{{q}_{0}}}={{a}_{0}},$$ p 1 q 1 = a 0 + 1 a 1 , …       , p n q n = a 0 + 1 a 1 + 1 a 2 + 1 a 3 + ⋯ 1 a n , ⋯ . $$\begin{align}& \frac{{{p}_{1}}}{{{q}_{1}}}={{a}_{0}}+\frac{1}{{{a}_{1}}}, \\ & \ldots \,\,\,, \\ & \frac{{{p}_{n}}}{{{q}_{n}}}={{a}_{0}}+\frac{1}{{{a}_{1}}+}\frac{1}{{{a}_{2}}+}\frac{1}{{{a}_{3}}+}\cdots \frac{1}{{{a

Simple Continued Fractions and Their Convergents

The article introduces simple continued fractions. They are defined as an infinite sequence of integers. The characterization of rational numbers in terms of simple continued fractions is shown. We also give definitions of convergents of continued fractions, and several important properties of simple continued fractions and their convergents.

Effect of cementite precipitation on the extend of bainite transformation in fe-cr-c steel

Analytical calculations and experimental measurements of volume fraction of bainitic ferrite and volume of the untransformed austenite indicate that there is a necessity of carbides precipitation. A consequence of the precipitation of cementite during austempering is that the growth of bainitic ferrite can continue to larger extent and that the resulting microstructure is not an ausferrite but it is a mixture of bainitic ferrite, retained austenite and carbides.
