They answered the basic questions of socialist value standpoint, and therefore, are the three indispensable fulcrums of Deng Xiaoping"s value viewpoint The people"s interests criterion, which brings to light the aim of socialist basic value, is the finest value criterion of socialism; the productive forces criterion, which reveals the means of socialist basic value, is the basic one ; the practice criterion, which tells us the basic approach to exploring and achieving socialist value, is the absolute judging criterion of socialist value .

其中，人民利益标准揭示了社会主义基本价值目标，是社会主义最高价值标准；生产力标准揭示了社会主义根本价值手段，是社会主义根本价值标准；实践标准揭示了探索和实现社会主义价值的根本途径，是社会主义价值的终极评价标准。

The experimental results indicates that the optimum pH range was 1.60~2.20, and the optimum H2O2 concentration was 10.0 mmol/L. The degradation ratio increased with the increasing concentration of ammonium ferric oxalate in the range from 0.1 to 1.0 mmol/L, but no significant increase in degradation ratio was observed when the concentration was above 1.0 mmol/L. When the concentration of fuchsin basic increased, the degradation ratio dropped, while the concentration of degraded fuchsin basic rised. When the concentration of fuchsin basic was low, the degradation followed first-order kinetics, but when it was high, the degradation could be fitted by zero-order kinetics. The absorbtion of fuchsin basic at 543 nm disappeared quickly, while the absorbtion of intermediates formed during the course of fuchsin basic dagradation at 298 nm vanished slowly.

试验结果表明：碱性品红降解的最佳初始pH为1.60~2.20，最佳初始H2O2浓度为10.0mmol/L；草酸高铁铵的浓度在0.1~1.0mmol/L时，碱性品红的降解率随浓度的增大而增大；高于1.0mmol/L时，则降解率相差不大；碱性品红的初始浓度增大，降解率减小，而实际降解的浓度则增加；碱性品红的浓度在低和高时，降解动力学过程不一致；随降解的进行，碱性品红在可见光区的吸收峰迅速消失，而降解过程中形成的中间产物吸收峰却消失很慢。

The "Basic" part refers to the BASIC (Beginners All-Purpose Symbolic Instruction Code) language,a language used by more programmers than any other language,Visual Basic has evolved from the original BASIC language,Now it contains several hundred statements,functions,and keywords,many of which relate directly to the Windows GUI,Beginners can create useful applications by learning just a few of the keywords,yet the power of the language allows professionals to accomplish anything that can be accomplished using any other Windows programming language.

Basic是指BASIC语言，这种语言的使用比其他任何语言都多。Visual Basic源于原来的Basic语言，现在已经有好几百条语句、函数、关键词，其中好多都是直接与Windows的图形用户界面有关。初学者通过学习少量的关键词就能创建有用的应用程序，而该语言的强大功能可以让专业人员实现任何用其他Windows编程语言所实现的功能。

Rule-based and reusebased method is adapted in our system to develop applications. Rules are used to define geometric representation of geographic objects, spatial relationships among geographic objects and map design rules. Reusability is realized through object's inheritance and encapsulation. The basic function related to GIS has been implemented in OOGDB's basic class base. Application related function can be implemented in sub-classes of basic classes and some of basic class' function can even be overloaded.

GIS应用系统的开发采用基于规则和基于重用的方法进行，规则用于定义地理对象的几何表示和空间关系以及地图构造的规则等，重用是通过面向对象的继承和封装机制实现的，GIS实现了一个基本的类库，它完成基本的空间处理和操作，用户通过定义这些类的子类重用类库提供的功能，并增加与应用系统有关的特殊功能，用户甚至可以通过重载修改某些类库的功能。
