Surveying and Mapping Hubei Province, the first director of the Vocational Skills Competition Organizing Committee, the Hubei Provincial Bureau of Surveying and Mapping, introduced the Secretary Jiang-Ren Chang, as China's economic construction, national defense, social development, the development of a more urgent demand for mapping, surveying and mapping work more and more important role prominent practitioners of surveying and mapping to a higher demand.

湖北省首届测绘职业技能竞赛组委会主任、湖北省测绘局局长张建仁介绍，随着我国经济建设、国防建设、社会发展的发展，对测绘的需求更加迫切，测绘工作的重要作用越来越突出，也对测绘从业人员提出了更高的要求。

To deal with the problems and present situation of field data capture by computer in geological mapping in 20 years, this paper has created PRB digital mapping techniques to standardize the digital mapping process and discussed PRB mapping technique-method system, including PRB digital mapping techniques, the model of PRB data and the related process, combinational regulations of PRB process, common mechanism and basic procedure of PRB process, data processing and dictionary of PRB, three-class PRB system,...

从近 2 0年地质填图中计算机野外数据采集技术研究的现状和存在的问题入手，在确定地质填图空间数据表达的基础上，遵循传统地质填图的规律，在不约束地质学家地质思维的前提下，既能满足计算机处理的需要，又能保证地质工作者取全、取准各项地质观测数据，在描述各类地质信息空间关系的基础上，创建了数字地质填图过程标准化和规范化的PRB数字填图技术，并对构成PRB数字填图技术、PRB数据模型、PRB基本过程、PRB基本过程组合的规则、PRB过程的公共机制、PRB过程基本程式、PRB数据操作、PRB字典、三级PRB体系、PRB数据流&栈&、PRB数据质量定量评价体系的PRB数字填图技术与方法体系进行了讨论。

The ann-injective rings start at the angle of annihilator,at the same time,the CT-injective rings start at the angle of cycle tortionless modules.

在第三章，我们引入了CT -内射维数的概念，从维数的角度来更进一步地认识CT -内射。

Moreover, we define weak principally quasi-injective modules and study Jacobson radical of endomorphism ring of weak principally quasi-injective modules.

另外我们还在主拟内射R-模的基础上定义了弱主拟内射R-模，利用零化子对弱主拟内射模上自同态环的Jacobson根的性质进行了讨论。

A ring R is called right co-semihereditary if every finitely cogenerated factor module of a finitely cogenerated injective right R-module is injective.

如果有限余生成内射右R-模的有限余生成商模是内射的，则R称为右余半遗传的。

So in chapter 2, we use P-flat and P-injective modules to characterize some important rings, like SF-rings, Von Neumann regular rings and Coherent rings, etc. In chapter 3, we introduce the homological dimension of P-flat and P-injective modules.

众所周知，正是由于研究各类模以及它们的同调维数，人们才能对环得到更深层次的性质的描述，所以在第二章中，我们就利用了P-平坦模与P-内射模来刻划几种重要的环，如SF环、Von Neumann正则环、凝聚环等。

Secondly, the equivalence proposition of right pm-injective ring is obtained, and if R is right pm-injective ring, then the Jacobson radical of R coincide with the right singular ideal.

其次，得到右pm-内射环的一个等价命题，并证明若R是右pm-内射环，则R的Jacobson根与R的右奇异理想相等。

In recently years, much progress about injective modules has been obtained, particulary about injective test sets and homological dimensions.

近年来，对内射模的研究已经取得了许多令人鼓舞的进展，特别是内射测试集和同调维数的研究。

On the base of the concept, we give the Schanual Lemma about weak injective modules and discuss the properties of the homomorphisms which can be extended in weak injective modules.

Kerβ的β∈Hom_R，都存在γ∈Hom_R使得β=γα成立，则称T为N-弱内射R-模，且称α为T与M的相伴同态。在此定义的基础上我们给出了弱内射模的Schanuel引理，讨论了弱内射模中能进行开拓的同态的性质。

The system can be widely used in belt weighing and batching process control,etc.

介绍了基于智能模糊控制的嵌入式配料系统的设计方法，对模糊PID控制过程和系统调零作了重点的讨论，同时给出了PID控制的程序流程图和系统定长调零子程序。

"I dunno," she answered,"but if you show me aroun', I'll recognize it from the lighthouse just outside the porthole."

"我不知道，"她回答说，"如果你能带我转转，我能认出来的，因为灯塔就在舷窗外。"
