Cluster analysis based on its pcr - rflp suggested that seven groups were distinguishable for pleurotus on 93 % similairity coefficient , i . e . p . oslrealus complex ( including p . ostreatus , p . florida , p . sapidus , p . corticalus , p . cornucopias , p . columbinus , p . spodoleucus , p . ferulae , p . nebrodensis and p . sp . ) , p . eryngii , p . pulmonarius - p Itspcr一rflp聚类分析结果表明， 52个侧耳菌株在93 %的相似系数水平可分为七类，第一类包括糙皮侧耳、佛罗以达侧耳、美味侧耳、裂皮侧耳、黄白侧耳、哥伦比亚侧耳、灰自侧耳、阿魏蘑、白阿魏蘑;第二类为刺芹侧耳;第三类包括月
We discussed the main characteristic parameters of seismic kinesiology and dynamics of mine engineering fracture zone , including relative amplitude , phase time of wave crest , similarity factor , principal frequency band energy , 3 - d space time gradient and coherent coefficient et al . , and puts forward the processing method of 3 - d seismic characteristic parameters about denoise - smoothing , generalization , correlation analysis , characteristic transformation ; and presents the method of pattern recognition of mine engineering fracture zone 摘要本文从时间域、频率域、三维空间域介绍了矿山工程裂隙破碎带主要的地震运动学、动力学属性参数，包括相对振幅、波峰相位时间、相似系数、主频带能量、二维空间时间梯度和相干系数等，提出了矿山工程裂隙破碎带三维地震属性的去噪平滑、归一化、相关分析、特征变换的处理方法以及裂隙破碎带的模式识别原理与方法，并用实例说明了该方法的应用效果。
In the paper , the esd stressing tests for n - channel mosfets are performed , and main electrical parameters , 1 / f noise spectrum and its time series are monitored during the test . it is found that the 1 / f noise changes much more sensitive to the esd latent damage than the electrical parameters , at the same time , similarity coefficient also changes more quickly especially for smaller w / l devices 通过对mos器件的静电应力试验，同时监测试验过程中器件的电参数、 1 / f噪声功率谱密度以及由1 / f噪声的时间序列提取的相似系数变化，发现1 / f噪声对于静电应力引起的损伤要比电参数的变化敏感得多。
To quite some degree , we can say that the conflicts of regional economic development process of our country display primarily in two aspects : one is the question of development gap and respect building among regions , the other is an unmoral appearance of economics connection among regions 摘要通过变异系数分析和结构相似系数的分析，可以在相当的程度上说明，我国目前在区域经济发展过程中存在的冲突主要体现在两个方面：区域间的发展差距问题和重复建设与区域间经济联系的不正常现象。
With respect to genetic similarity , genetic distance and cluster analysis among samples of f1 generation , it showed that the most genetic identity is between jfp and jmp , ( i = 0 . 9934 , dnei = 0 . 0066 ) , the next was between jp and jmp ( i = 0 . 9873 , dnei = 0 . 0128 ) , the third was jp and jfp , with i = 0 . 9681 , dnei = 0 . 0325 ; the fourth was jp and cp , with i = 0 . 9035 , dnei = 0 . 1015 ; the fifth was cp and jmp , with i = 0 . 8862 , dnei = 0 . 1208 , and the furthest was between cp and jfp , with i = 0 . 8648 , dnei = 0 . 1452 由此可以看出在此四组中，杂交组的遗传变异明显高于自交组的，杂种优势已初步显示出来。而在两杂交组中，日雄中雌杂交组又优于日雌中雄组中自交组。群体间遗传相似系数和遗传距离及聚类分析结果表明：两杂交组间的遗传相似系数最大，遗传距离最小，仅为0 . 0066 ，而中自交组群体与日雌中雄杂交组群体的遗传距离最大为0 . 1452 ，两自交组群体间的遗传相似系数为0 . 9035 ，遗传距离为0 . 1015 。
So it was enlightened that t . jackii still had a high level of genetic diversity . the similar index between the t . jackii populations from jiangshi nature reserve and xufan reservoir was higher than that between the populations from jiangshi nature reserve and xufanggeng . it was determined by geographical factors 聚类分析表明将石自然保护区的长叶榧居群与许坊水库的相似系数较大，而和许坊埂的相似系数较小，这和地理上将石自然保护区和许坊水库邻近，而许坊埂距前两者较远的事实相符。
This paper compares and analyzes the associated situation of the several input and output forms of china since the innovation , protracts the chart of the association of industries . this paper presents the following innovation : 1 . this paper analyzes and compares the similarities and differences of the three industries of china and the developed countries and the countries with the similar level of economy of the static state and the developing state 本文的主要创新点有: 1 .采用产业结构相似系数等方法对照分析改革开放以来各个发展时点以及各时点之间我国产业结构与典型发达国家、经济发展水平相当的代表国家的产业结构,从水平状态与动态演变两个角度揭示我国产业结构与典型发达国家之间的异同之处。
Elevation , features of slope , vegetation , tree and shrub coverage , height , panda traces ( droppings , dens , individuals , gnawing bamboo stems ) in each plot were recorded to characterize the population size of the giant panda , their habitats and impacts of human disturbance on pandas at wanglang 种群数量估计中，以每块粪便中bsf的平均长度作为它的bsf平均长度，采用多重比较和相似系数方法对bsf平均长度进行分析和比较，识别粪便是来自同一个体还是不同个体，从而估计保护区的大熊猫种群数量。
It may suggest that h . patula had different genomes from leymus , psathyrostachys and the other three species of hystrix in this study . 6 . comparison between the results from rapd and those from issr , it is concluded that : ( 1 ) 40 random primers were screened for rapd fragments , 20 primers produced polymorphic rapd products （ 2 ）结果分析的比较：通过两种不同dna分于标记得出的伽tris 、 lcymus和psathmptachys三个属间的jaccard遗传相似系数及遗传聚类图具有极显著的相关性，表明研究中所用的rapd和issr标记数量可以检测到这些遗传变异。
The rapd - pcr analyses were conducted with different colour basidiocarps from different origin pleurotus mushrooms . the results showed that there are same dna fingerpringing patterns among the mycelial isolates , pileus ( including lamellae ) and stipe from one basidiocarps , but the similarity coefficients between different origin and colour basidiocarps vary from 0 . 779 to 0 . 976 试验结果还表明：人工栽培产生的子实体及其组织分离菌丝体，与所用栽培菌种茵丝体及其种源子实体，都具有一致的rapd指纹图谱：而不同来源的子实体之间的dna相似系数在0 . 886 0 . 986之间。
