E . e . enochs put forword the concepts of injective ( projective or flat ) ( pre ) cover and ( pre ) envelope in the early 1980s " , a lot of articles have studied existence and uniqueness of such ( pre ) covers and ( pre ) envelopes , the property of their kernels or cokernels , and character many special rings . moreover , if such kind of ( pre ) covers or ( pre ) envelopes exist , we can construct a complete injective ( projective or flat ) resolvent ( called resolution when exact ) and a partial injective ( projective or flat ) resolvent , and if r is a ring , we can study the relationship of its left global dimension l . d ( r ) ( or its weak dimension w ( r ) ) and the properties of syzygies ( or cosyzygies ) of a resolvent ( or resolution ) , and the relationship of its left global dimension l . d ( r ) ( or its weak dimension ) and the exactness of a resolvent ( or resolution ) 自八十年代初e . e . enochs首次提出并研究内射(投射、平坦) (预)盖及内射(投射、平坦) (预)包这些概念以来，大批论文研究此类包、盖的存在性、唯一性问题以及它们的核、上核的性质，并据此刻画了一些常见的特殊环；更进一步地，当此类包、盖存在时，我们可构造相应的完全投射(平坦、内射)预解式(当正合时称为完全分解式)以及单边投射(平坦、内射)预解式，研究了环的左(右)总体维数、弱维数与此类分解式的合冲模(或上合冲模)的性质、复形正合性之间的关系。
In section 3 , we show that when i is a squarefree stable ideal , shiftij ( i ) and i have the same graded betti numbers , projective dimension and regularity , then ic and i have the same graded betti numbers , projective dimension and regularity . at last we apply the results we obtained to simplicial complexes 在第三节中证明了当i为无平方稳定理想时， shiftij ( i )与i的分次betti数、投射维数和正则度相同，从而i ~ c与i的分次betti数、投射维数和正则度相同，最后将所得结论推广到单纯复形上。
The reference values of strength parameters of the grounds and rock - fillers of the high rock - filled embankment on liuzhai - shuien highway in guangxi are obtained in this paper by synthetically analyzing the construction technology at home and abroad and indoor rock tests . by comparing the analysis method of settlement laws and thoroughly analyzing the datum of the embankment settlements of liuzhai - shuiren highway from the whole cons truction period , a new method generated from expectation technology to analyze the embankment settlement laws , " compete " growth curve , is presented in this paper and the result tallies with the observation data . for there are shortcomings in indoor rock tests , in this paper by combining finite element method with duncan - chang nonlinear constitutive model and composite method , a method for back analysis of the strength parameters of rock fillers is presented with a corresponding program , which has been successfully applied 通过对国内外已有高填石路堤修筑资料的综合分析及室内岩石试验，获得了寨任二级公路高填石路堤地基及填料强度参数的参考值；通过对路堤沉降发展规律现有分析方法的比较及对广西寨任二级公路高填石路堤修筑工程中的沉降全过程观测资料深入分析，运用预测技术，提出了路基及路堤沉降发展规律分析的“龚帕斯”成长曲线分析方法；针对室内岩石试验的局限，运用有限元技术，结合邓肯一张非线性本构模型和复形调优法，提出了高填石路堤填石料强度参数的反演方法，开发了相应的反演分析程序，并成功地反演了广西寨任二级公路高路堤填石料的强度参数值。
