可闭算子

At last,we apply Tikhonov reg-ularization method with closed operators to solvc nonlinear ill-posed problems,undercertain conditions,we obtain optimal convergence rates of regularized solutions.At thesame time,we also discuss the case when the"attainability"condition is not satisfied.

最后我们应用带闭算子的Tikhonov正则化方法研究非线性的不适定问题，在一定的条件下得到了最优的收敛率，并讨论了当"可达性"条件不满足的情况下的正则化。

Different from the former study,the value region of projective operator in the neural network which they study was a general closed convex subset of n demensional Euclidean space and it wasn't a compact convex set in general,that is,the value region of projective operator was probably unbounded.

与以前研究投影算子的值域一般是n维欧氏空间中的紧凸子集不同，而是n维欧氏空间中未必有界的闭凸子集，同时目标函数也是一般的连续可微函数，未必为凸函数。

The well-known spectrum assignment problem are discuussed and a general proofs for it and its generalization are gived. 3. The general conditions of invertible completions of operator pairs are acquired.

作为研究基础，引入了算子对可控性与可容许性指标及算子ε-限制，并利用算子闭值域特性、值域逼近及空间的不同分解，获得了算子谱配置问题及广义的算子谱配置问题一般性证明。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
