小明家的太阳能热水器，水箱最多可装水100kg．小明进行了一次观察活动：周日早上，“温度传感器”显示水箱中的水温为20℃，然后给热水器水箱送满水，中午时“温度传感器”显示水箱中的水温为50℃．水吸收的热量是______J，如果水吸收的这些热量，由燃烧煤气来提供，而煤气灶的效率为80%，至少需要燃烧______kg煤气，这些热量如果由“220V  1000W”的电热水器来加热供给，至少要______h．[c_水=4.2×10³J/（kg•℃），煤气的热值为q=4.2×10⁷J/kg，不考虑电热水器的热损失]．

The Turing machine is an abstract (71) of computer execution and storage introduced in 1936 by Alan Turing to give a mathematically precise definition of (72) . or ’mechanical procedure’. As such it is still widely used in theoretical computer science, especially in (73) theory and the theory of computation. The thesis that states that Turing machines indeed capture the informal notion of effective or mechanical method in logic and mathematics is known as Turing’s thesis.

Every Turing machine computes a certain (74) partial function over the strings over its alphabet. In that sense it behaves like a computer with a fixed program. However, as Alan luring already described, we can encode the action table of every Turing machine in a string. Thus we might try to construct a Turing machine that expects on its tape a string describing an action table followed by a string describing the input tape, and then computes the tape that the encoded Turing machine would have computed. As Turing showed, such a luring machine is indeed possible and since it is able to simulate any other Turing machine it is called a (75) Turing machine.

A universal Turing machine is Turing complete. It can calculate any recursive function, decide any recursive language, and accept any recursively enumerable language. According to the Church-Turing thesis, the problems solvable by a universal Turing machine are exactly those problems solvable by an algorithm or an effective method of computation, for any reasonable definition of those terms.
