With the rapid development of computer science, combinatorics, an ancient subject of mathematics, has shown new vitality. Therefore, related problems are often encountered in mathematics competitions. This chapter only discusses the two most basic combinatorial rules, which are the rule of sum and ...

The sum rule for the transition rates between the components of two multiplets, known for the one-photon transitions, is extended to the multiphoton transitions in hydrogen and hydrogen-like ions. As an example the transitions 3p – 2p , 4p – 3p and 4d – 3d are considered. The numerical...

The recent experimental determination of the Gottfried sum rule of deep inelastic scattering provides strong evidence that SU(2) flavor symmetry is broken by the sea quark distributions of the nucleon. Two mechanisms have been suggested to explain the data: Pauli blocking and non-perturbative contribu...
sum-of-the-digits method 数字总计法又称rule of 78,是一种计算利息退款(interest refund)的方法。在美国,是指分期付款之买方提前偿还债务;卖方计算其应还融资费用的方法。以一年期的贷款契约而言,第一个月计点数为12点,下月依11点,至最后一月为1点,12个月总计是78点,因此有rule of 78的别称。相关...
We will only prove the sum rule because the rest can be proven in a similar manner. Let f(x) and g(x) be differentiable functions. We set j(x)=f(x)+g(x). By the limit definition of derivatives, we will have $j'(x)= = \frac{j(x+h)-j(x)}{h}$ ...
We present a QCD sum rule calculation of the Isgur-Wise form factor τ1(vv′) and τ2(vv′) for the semileptonic decays BD1(2420)lν and BD2*(2460)lν in the framework of heavy quark effective theory. These two universal functions, associated with the matching of the weak currents in...
