We find that, i the diagrams withthe annihilation topology have a suppression factor 〓 relative to those withspectator topology; ii our results are much different from other model predic-tions for some decays modes; iii the pure W-exchange process 〓with a branching ratio 〓 can be found even before the B-factory era;iv for B →ππ,πK and KK decays, our results are well below the experimen-tal upper limits, but they are about one order of magnitude below the BSWpredictions.

Because Lambert W function is defined as the solution of a transcendental equation,and it works only if some mathematical softwares such as Maple,Matlab or Mathematica are available,so the stability criteria based on Lambert W functions are not easy for understanding in applications.

但由于Lambert W函数是一个超越方程的解，而且它的求解需要借助数学软件 Maple，Matlab 或Mathematica才能完成，因此在理解和应用上都有一定困难。

The conventional method of preparing fine cemented carbide is to reduce and carburize fine W and WC powder at low temperature, then inhibitors,such as TaC, Cr3C2 and VC, are usually added into the powder to prevent the WC grains from coarsening during sintering.

制取这种微晶硬质合金通常的方法是，用还原和碳化方法，首先得到细W粉和WC粉，然后加入TaC、Cr3C2和VC等晶粒长大抑制剂，并且通常是将这些抑制剂加入到W粉或WC粉中，防止WC晶粒在烧结时长大变大变粗。

The heterogeneous W-HMS catalyst was in-situ prepared by immobilization of tungstic acid on hexagonal mesoporous silica. It was used to synthesize glutaraldehyde from cyclopentene.
