In the historical evolution of mathematic thought, content and method, m athematic truth has assumed some postmodern characteristics.The targets of the pursuit of mathematic truth have changed from the objectives and valu es of metaphysics to the relative and varied theoretical constructions.Mat hematic truth is an open system with different levels and frameworks. It h as transcended the scope of natural truth and has generated a new dimensio n,i.e.,selectivity.Both formalization and non-formalization are effec

在数学思想、内容与方法的历史性变革过程中，数学真理的观代性开始发生转向，逐步表现出一些后现代特征：数学真理从追求形而上学的目标与价值转向追求相对的、多样化的理论构建；数学真理是一个具有不同层次性和等级结构的开放体系；数学真理超越了自然真理的范畴，开始生长出一种新维度——可选择性；形式化与非形式化都是获得数学真理的有效手段。

It was found that these as-prepared MgO materials replicated the biomorph of pinewood, and their frameworks were constructed by plenty of claviform nanoparticles with a similar sectional area, which were different from those of MgO prepared by directly thermal decomposition of MgO precursor.

结果表明，用该方法制备出来的MgO样品具有松木的生物形态，由横截面积比较均一的棒状纳米颗粒构成，不同于乙酸镁直接焙烧得到的MgO样品。

After this research work, we know that: HMCM-22 is a better catalyst of selecting naphthalene alkylation; Surface modification of zeolite Y is effective, but the effect of zeolite 3 is not evident and surface modification doesn"t suits mordenite; Surface modification doesn"t affect the frameworks and inner environments of zeolites, but only reduces diameter of orifice and overlays surface acidities; t-butanol is not suitable for alkylating agent of the reaction using modified zeolites as catalyst; Solvents with smaller molecular size are advantageous for naphthalene alkylation reaction using modified zeolites as catalyst, such as cyclohexane is better than decalin.

通过本论文的研究，我们知道：HMCM-22是萘择形烷基化反应较好的沸石之一；Y沸石的外表面改性效果较好，β沸石则效果不明显，而丝光沸石则不适于外表面改性；外表面改性不改变沸石的骨架结构和孔道内部环境，仅减小孔口直径和覆盖外表面酸性位；叔丁醇不适于作外表面改性沸石催化的反应的烷基化试剂，其反应活性很低，且选择性无明显提升；分子较小的溶剂更适于外表面改性沸石催化的反应，环己烷就明显好于十氢萘。

In other words a national government will have particular social and economic policy imperatives which determine the interpretation of definitional frameworks which may vary when interpreted at state or regional or local levels.

换句话说，国民政府有具体的社会和经济政策规则，来解释这些概念性框架，而国家、地区和地方部门对这些概念性框架的解释可能会有所不同。

This paper summarizes various structural models, structural belts, Cenozoic deformation frameworks and tectonic evolution concerning intraplate deformation in the West Kunlun - Pamir Cenozoic erogenic belt and Southwest Tarim foreland basin and suggests that the Cenozoic intraplate deformation be characterized by segmentation and stage evolution.
