NEWTON-LIK E METNODS IN PARTIALLY ORDERED BANACH SPACES

We provide convergence results and error estimates for Newton-like methods in generalized Banachspaces.The idea of a generalized norm is used whichis defined to be a map from a linear space into a partiallyordered Banach space.Convergence results and error estimates are improved compared with the real normtheory.

On the behaviour of artificial head transfer system applied to acoustic evaluation researches for halls

The author has made tests for an artificial head transfer system whichis modelled on a Chinese male on its main physical behaviour such as frequencyresponses,frequency response differences between the front and the rear inci-dences,as will as on its important hearing behaviour such as localization,theperception of distance and room dimensions.The results verify that this kind ofartificial head transfer system can be used as one of effective tools of acousticevaluation researches for halls.     

CO和H_2在沉淀铁催化剂上的化学吸附和程序升温脱附

铁催化剂是一种重要的F-T 合成催化剂。本文的目的是通过CO 和H_2在浆态相F-T合成采用的无载体沉淀铁催化剂上的化学吸附和程序升温脱附(TPD)的实验结果,考察钾的加入对催化剂性能的影响。实验采用共沉淀法制备的Fe-Cu(Fe65w%;Cu 0.6w%,其余为平衡氧)和Fe-Cu-K(Fe,Cu 含量同上,K0.1w%,其余为平衡氧)两种催化剂。程序升温脱附实验在装有四极质谱仪的吸附-解吸系统内进行。化学吸附用Chemisorb 2800装置测
