As I said,many of us were old,and most of us were indoor men,and I was amused to see how close to the head some of us held our hats,the merest barleycorn of interval being maintained for reverence sake,wheras the sexton and the clergymanb had slipped on those black velvt skull-caps which God,in his infinite mercy,either completely overlooks,or seeing,smiles at.

我已经说过，我们之中许多人都上了年纪，大部分平时又是深居简出，这时候他们手里拿着的帽子贴着脑瓜那么近，为了对死者表示敬意才挪开一颗大麦粒那么大的距离，我看着心里不禁感到好笑，与此同时，教堂的工役和牧师却早已悄悄带上他们那黑天鹅绒的小帽，对此，无限仁慈的上帝若非一时没有瞅清，定是看了而一笑置之。

Based on the flaw of the probability reliability model in the case of small amount of information,non-probability and mixed probability/non-probability reliability models are presented. When the uncertainty of the basic random variable is described by convex, analytical and numerical methods are constructed to calculate the convex of response variable. The infinite norm index, which is the minimal infinite norm distance from original coordinate point to the surface of the limit state in the standard interval space, is presented to measure the safety of the structure.

Firstly, the existence and uniqueness of the solution for neutral stochastic functional differential equations with infinite delay under the uniformly Lipschitz condition, linear grown condition and contractive condition can be directly derived; And the moment estimate of the solution and the estimate for error between the approximate solution and the accurate solution can be both given; If the uniformly Lipschitz condition is replaced by the local Lipschitz condition, the existence and uniqueness theorem can be gained; Meanwhile, the existence and uniqueness of the global solution in the interval 0,+∞ can also be obtained; Secondly, L~p-exponential estimate of the solution for neutral stochastic functional differential equations with infinite delay can be studied; At length, the theorem of the local solution about neutral stochastic functional differential equations with infinite delay only under the local Lipschitz condition and the contractive condition can be established.
