The criterion is similar to hyperbolic strength criterion including uniaxial compression strength and uniaxial tensile strength, which is an extended form of Griffith-Murrell criterion essentially under the condition of polyaxial stress when hydrostatic pressure is lower, and it represents the first failure type. However, the criterion is similar to generalized Mises criterion when hydrostatic pressure is higher, and it represents the second failure type. The transition part between the two criteria represents the third failure type when hydrostatic pressure is high.

该准则包含单轴抗压和抗拉强度，在静水压力较低时，实质上它是Griffith-Murrell准则在多轴应力状态下的一种扩展形式，反映脆性岩石破坏类型1；在很高静水压力下该准则可转化为广义Mises准则，反映脆性岩石破坏类型2；而当静水压力较高时，该准则处于上述两种准则的过渡阶段，反映脆性岩石破坏类型3。

According to the degrees of PSC they have,Shanghai-accented Mandarin interlanguage are classified into four stages as elementary ,intermediate ,intermediate-advanced and advanced.Then the phonologies of Standard Mandarin and Shanghai-accented Mandarin interlanguage are compared in order to find out the phonological differences between these two dialects. Based on the statistical results, the writer chooses ten typical kinds of pronunciation errors of finals according to the rates of pronunciation errors of finals on stages.Then, the phonetic level analysis is made on them for the four stages respectively. Furthermore, acoustic features of vowels, diphthongs, triphthongs and vowels with nasal endings are analysized and compared by plotting vowel charts and formant patterns for them. Finally, the writer gets some preliminary results of the typical pronunciation errors of finals during the whole process of Shanghai-accented Mandarin interlanguage and on the stages of it respectively.

本文结合当前这种实际研究和应用的需要，以上海地区普通话过渡语为考察对象，从韵母发音偏误入手，借鉴第二语言习得研究中偏误分析和中介语研究的相关理论，采用实验语音学的方法，随机选取了80位上海地区不同普通话水平等级的应试人的应试录音和试卷作为本研究使用的语料，并将其分别对应于上海地区普通话过渡语的四个阶段，重点考察这80位处于不同阶段的应试人在测试的读单字部分的韵母发音偏误现象，通过对各阶段所有应试人的各类韵母发音偏误出现率的统计分析，展示出上海地区普通话学习者在韵母习得方面产生的偏误在过渡语各个阶段上的分布特点及趋势；再根据各阶段各韵母发音偏误率的统计结果，选取各阶段共同具有的十类主要的韵母发音偏误，分别绘制过渡语各阶段的偏误音声学元音舌位图或共振峰模式图，并与标准普通话中相应韵母的声学元音舌位图或共振峰模式图进行比较，从而展示出上海地区普通话学习者的主要韵母偏误类型在过渡语不同阶段上各自的声学特征、偏离标准音的程度和相关趋势，并从一定程度上反映了这一地区普通话学习者在韵母习得方面的能力发展轨迹，为普通话教学及培训中如何提高教学效率问题提供一定的参考依据，也为普通话水平测试各等级标准声学特征的建立，乃至为将来测试的计算机化提供了可靠的声学参数。

The cluster result revealed the evolution tendency of Rosa plants. Original character was white and simple petal. Modern character of Rosa cultivars was Larger and double flower. The Rosa of pink semi-double petal was the transition from wild species to modern cultivars.

聚类结果显示出了蔷薇的演化趋势：白色、单瓣是蔷薇较为原始的一个性状，花径大、重瓣性高是现代蔷薇栽培品种的性状，而部分粉红色半重瓣蔷薇则是从野生种到现代栽培品种的中间过渡类型。

Consulting the genetic identity it was shown that six-rowed wild close barley is closer to cultivated barley than two-rowed wild close barley. This result supported the viewpoint that the six-rowed wild close barley was the intermediate type in the evolutionary route from the tow-rowed wild close barley to the cultivated bar-ley.
