  concept of number
Arithmetic, on the other hand, initially focuses on the action of counting and later changes focus to the use of symbols for both the process of counting and the concept of number.
      
It takes the deliberate naming of concepts to help crystallize and secure those observations and intuitions as abstract concepts, and to begin separating the concept of number from specific instances of objects.
      
So it is necessary to analyse the concept of number inthe system of Neoplatonic thought.
      
The aim of this paper is to present the Nyāya concept of number in the light of contemporary philosophy and to show that the Frege-Russell concept of number does not contradict the Nyāya concept of number but rather supplements it.

By extending the concept of isospin and Strangeness' to leptons, We have determined the isospin T and Strangeness S for leptons from the generalized Gell-Mann -Nishijiraa formula. Then, With the aid of the selection rule of the total Strangeness , We obtain a Lang-rangian of weak interactions with the "current and current" coupled form of weak currents in place of the "(total current)X (total current)" coupled form, which is Suggested by Fcynman and Gell-Mann. This model has the following Properties for the...

By extending the concept of isospin and Strangeness' to leptons, We have determined the isospin T and Strangeness S for leptons from the generalized Gell-Mann -Nishijiraa formula. Then, With the aid of the selection rule of the total Strangeness , We obtain a Lang-rangian of weak interactions with the "current and current" coupled form of weak currents in place of the "(total current)X (total current)" coupled form, which is Suggested by Fcynman and Gell-Mann. This model has the following Properties for the weak interactions: (i) Whirh Produces AS=+AQ processes for the leptonic decay of Strangeparticles; (ii) Which forbids AS >1 processes; (in) Which obeysapproximately the 1/2 rule for the nonleptonic weak process ofStrange particles; (iv) absence of the neutral leptonic weak currents; (v) absence of the neutrino flip processes; (vi) which is consistent with the intermediate vector boson theory.

将同位旋与奇异数的概念推广到轻子,借助推广了的Gell-Mann-Ni-shijima公式,确定轻子的同位旋T与奇异数S。然后,从总奇异数的选择规则|△S|≤1出发,代替Feynman与Gell-Mann的“(总流)×(总流)”耦合形式的弱相互作用拉格朗日函数,我们得到一个由“流与流”耦合表征的弱相互作用拉格朗日函数。本模型具有以下一些主要性质:(i)能引起△S=±△Q的奇异粒子的轻子衰变;(ii)将禁戒|△S|>1的过程;(iii)奇异粒子的非轻子衰变近似地遵从|△(?)|=1/2定则;(iV)不存在中性轻子弱流;(Vi)能与传递弱相互作用的蹭矢量玻色子理论相容。

A series of Pt-Al2O3 catalysts were investigated by the CS2 poisoning method. For characterizing the nature of active site, a new expression was suggested: the activity frequency was used to relate the strength of active site and the concept of number of multiplet active atoms was introduced for describing the mode of active site forming, based upon which the calculating formulas and the method of measurement were proposed.

本文对金属催化剂活性中心性质提出了新的表征方法,即用活性频率量度活性中心的强度,用原子组合数的概念描述原子组成活性中心的方式,在此基础上提出了活性频率和活性中心原子组合数的计算公式与新的测定方法。 从测出的活性频率和活性中心原于组合数的数据,发现了Pt-Al_2O_3催化剂具有两种活性中心即α和β中心。α中心CS_2的吸附能力比β中心强,但β中心对环己烷的脱氢活性比α中心强。同时证明了不管在α中心或在β中心上环己烷的脱氢反应都是在双位中心上进行的。 本文还考察了锡和铼对铂催化剂性能的影响,实验表明锡和铼都能从结构效应和电子效应方面影响铂的催化性能。
