The multimode waveguide area is one multimode interferencearea provided with two refractive index variable regions.
多模波导区是一个多模干涉区，其上设有两个折射率可改变的区域。

The viewpoint that the interferencearea of the stress - strength interference model in reliability design is the probability of failure is discussed in this paper.
本文对可靠性设计中应力—强度干涉模型的干涉面积就是失效概率的观点，提出商榷。

Numerical results also show that the interferencearea is not equal to the probability of failure, and the relationship between them can not be expressed by simple mathematical expressions.
