Seven years later, in 1675, the three volumes for April appeared, preceded by preliminary treatises, the subjects of which were respective: in the first volume, the two most ancient collections of notices on the popes (catalogues of Liberius, and Felix) and the date of St. Ambrose's death, both by Henschen; in the second, the attempt at a diplomatical treatise by Papebroch,"whose chief merit", as the author himself was fond of saying with as much sincerity as modesty,"was that it inspired Mabillon to write his excellent work:"De re diplomatica"; in the third, a new revised edition of the new revised edition of the "Diatribi de tribus Dagobertis, which had made the name of Henschen celebrated twenty years previously.

七年之后，在1675年，共三册，为4月出现，在此之前的初步论文，课题，其中分别有：首先是体积，这两个最古老的收藏告示教宗（目录的利比里奥，和Felix ）当日圣刘汉铨之死，无论是由亨申，在二，图谋在diplomatical伤寒由papebroch &，其主要好处&，如作者自己喜欢说的，与作为有多少诚意，因为谦虚，&就是它灵感mabillon写他出色的工作：&去重新diplomatica &，在第三，一个新的修订版的新修订版的& diatribi德tribus dagobertis ，其中已作出的名义亨申庆祝二十年以前。

The Greek translator states in his preface that he was the grandson of the author, and that he came to Egypt in the thirty-eighth year of the reign of Euergetes, an epithet borne by only two of the Lagi, Ptolemy III.

希腊翻译国在他的前言，他的孙子的作者，他来到埃及在第三十八年在位Euergetes ，所承担的形容词只有两个搜索，托勒密三。

Introduced in the third chapter with 区间套 theprinciple, the true principle, the fluxionary calculus proved threemethods have carried on the proof to a zero theorem; Then introduces azero theorem the promotion; Finally introduced the zero theorem twoapplications.

在第三章中介绍了用区间套原理、确界原理、微积分证明三种方法对零点定理进行了证明；接着介绍零点定理的推广；最后介绍了零点定理的两个应用。

At present, all the P-Y curve methods recommended by the referring code demand using geotechnic parameters C_u (three-axle undrained shear strength) and ε_50(the strain value that is equal to a half of the difference stress in the undrained triaxial compressing test). Moreover, we must do the complex and expensive triaxial geotechnic experiment to get those two geotechnic parameters, so they restrain the P-Y curve method from using comprehensively.

但目前国内外有关规范推荐的P-Y曲线均需用到土工参数C_u和ε_(50)(三轴不排水压缩试验中最大主应力差一半时的应变值)，而获得这两个参数需要进行比较复杂且费用较高的土工三轴试验，限制了P-Y曲线法的广泛应用。

Our previous studies have shown that ubiquitous overexpression of HmgD caused hemocytes proliferation and the formation of melanotic tumors in the Drosophila larvae. To clarify the mechanism of melanotic tumors appearance,we also generated RT-PCR analysis to test the transcriptional changes of PPAE and Spn27A,which encode the key factors in the phenoloxidasecascade pathway from larvae samples of mid-third instar,late-third instar and prior to pupation relative to wild type flies.Our result showed that in the HmgD overexpression mid-third instar larvae,the expression level.of Spn27A was lower than wild type,otherwise the expression level of PPAE was higher than wild type.It suggests that overexpression of HmgD affects the PO cascade pathway.

本研究组前期工作发现，过量表达HmgD引起果蝇幼虫体内血细胞增生，并出现黑色素瘤，为探讨HmgD过量表达导致了血细胞增生即形成黑色素瘤的分子机制，本研究分别提取三龄中期、后期和相对于野生型化蛹前时刻的幼虫的RNA，首先检测了编码酚氧化酶级联反应途径中的两个关键基因PPAE，Spn27A在突变体中的转录发生变化，结果发现，Spn27A在三龄中期的表达量低于野生型，而PPAE的表达高于野生型，表明过量表达HmgD影响了酚氧化酶级联反应途径，低水平的Spn27A不足以抑制PPAE的活性，活化的PPAE催化了PPO的活性，使其转变成有活性的PO，从而促进黑色素的生成，使果蝇体内产生黑色素瘤。

In Chapter 3,we derive the second-order-derivative-free iterations with two parameters from the third-order iterations with one parameter to approximate the roots of nondifferentiable equations in Banach space.

第三章，从带一个参数的三阶迭代族出发，构造了一族免二阶导数计值带两个参数的迭代族，用其去逼近Banach空间中非线性算子方程的解。
