令r = 01 | 10, 则R = 0r*, 令所求的正规文法为G [S]则有: S → 0M ,M → r*, 由上述结论可直接得 M → rM | ε 将r = 01 | 10回代到M中,得M → (01 | 10)M | ε, 展开后得M → 01M | 10M | 01 | 10, 将0、1开头的产生式分别合并,得M → 0 (1M | 1) | 1 (0M | 0)
Basic reproduction number - Wikipedia
In epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate), denoted (pronounced R nought or R zero), [1] of an infection is the expected number of cases directly generated by one case in a population where all individuals are susceptible to infection. [2]

The basic reproduction number (R - PubMed
The basic reproduction number, R nought (R 0), is defined as the average number of secondary cases of an infectious disease arising from a typical case in a totally susceptible population, and can be estimated in populations if pre-existing immunity can be accounted for in the calculation.

Solve r (r-10)=0 | Microsoft Math Solver
How to calculate circumference of circle in Lp? If p= 1, then the "circle" is a square with corners (r,0), (0,r), (−r,0), and (0,−r). To see this, note for example that the line through (r,0) and (0,r) has equation x+y = r. For ... Let f (x)= C (x)− 21rs(x). Then f ′(x)= C ′(x)− 21rs′(x)= 0 for all x.
Find the Equation of the Circle (0,0) , r=10 | Mathway
The standard form of a circle is x2 x 2 plus y2 y 2 equals the radius squared r2 r 2. The horizontal h h and vertical k k translations represent the center of the circle. The formula is derived from the distance formula where the distance between the center and every point on the circle is equal to the length of the radius.
