无特征的

It is also the rise of modern chorus. It breaks from the tradition, showing modern techniques and styles such as polytonality and atonality.

Malignant melanoma can occur from skin, or any internal organs, among which skin melanoma is more frequently seen, especially in the skin of legs, cunnus, and crissum. However they have been rarely reported. Malignant melanomas of the internal organs can be easily diagnosed with its specitic MRI features, while the non-melanin contained melanoma which has no imageological specific feature are more difficult to be diagnosed. Because CT examination has no specific feature, MRI should be the first choice, for the suspect patient of malignant melanoma.

恶性黑色素瘤多发生于皮肤、内脏各种组织器官，其中皮肤恶性黑色素瘤多见，以下肢、外阴、肛周最多，鲜有影像报道；发生于内脏的恶性黑色素瘤多因具备特征性的MRI信号得以诊断，而不含黑色素的恶性黑色素瘤影像表现无特征性，诊断困难；CT检查不具备特征性，对于怀疑恶性黑色素瘤的患者，应首选MRI检查。

Methods An unsupervised local and global features extraction method was adopted for the localization of facial features of frontal view face image. First, a threshold was used to segment the image into foreground and background, and the nose was localized by considering the symmetry of the face. Second, Harris operator was adopted to detect interest points in a rectangular area covering all the facial features, and then local maximum of the interest points were detected. And finally, Kmeans clustering method was used to cluster the points and obtain the facial features localization.

针对红外正面脸部图像，采用一种无监督的局部和全局的特征提取方法，首先通过阈值法区分出前景和背景，并根据面部特征对称性在前景中确定鼻区；然后在面部确定一个包含所有特征的矩形区域，利用Harris算子在该区域检测出角点，并找出这些点的局部最大值点；最后用Kmeans方法对这些点进行聚类。

The system utilizes the semanteme characteristic and structure characteristic of the text to make the states with certain characteristics.

该系统基于文本分块，利用文本的语义特征和结构特征，抽取具有特征的状态，在此基础上，利用反向动态规划和正向A*算法，抽取剩余的无特征状态。

It is often used to describe problems in dynamics, control theory, bionomics and economics, epidemiology and many other fields either about its experimental or applied aspects, because it can reflect facts more veraciously using the delay differential equations to solute the above problems considering the influence of time and lag sufficiently.

在时滞微分方程的研究方面，从一般的特征方程到超越特征方程，从无参数的微分方程到有参数的微分方程，从无时滞的微分方程到有一个时滞的微分方程直至两个甚至多个时滞的微分方程为题的研究，经历了一个发展相当快的过程。

There are no distinct differences between ancestral character state and descendant character state in some characters. 4. Only one outgroup can't give enough information to tell what the ancestor looks like. It make us not to understand how a lot of charactors evolved. 5. The matsutake group is polyphyletic. 6. The character coding is not precise enough. 7. Some characters are not homology. The result of molecular systematic study on the matstuake group shows the group is not monophyletic. The matsutake group is more closed to Tricholoma than Armillaria. ITS sequence of Catathelasma ventricosum is nearly identical to that of the matsutake group, although apparently they are very different from each other in morphological characters.

对松口蘑群通过形态学特征进行系统发育关系分析造成很大的干扰的原因有：松口蘑的种类大多形态特征比较简单，可提供进行分析的特征不多；某些性状在一些状态之间的反复转化，造成分析上的误差；在进化过程中某些性状无明显的祖征和衍征，在分析过程中很难确定进化极性；选择外群时应该用一个特定类群进行整体理解后，确定各个性状的极性，不要只用单种作为外群；松口蘑群是一个多系群；进行比较的性状不一定是同源的；数量性状编码过于粗放，反映不出真实的情况。

In the end ,it comes to the conclusion that the phase behavior of gas condensate considering effect of reservoir deformation,capillary force,capillary condensation and interfacial adsorption is not only notably different from phase behavior in PVT cell but also remarkably different from phase behavior in indeformable and porous media. therefore,it is

最后得出结论，储层变形、界面吸附、毛细凝聚、毛细管力对凝析气藏油气体系相态特征有重要的影响，其相态特征显著不同于常规不考虑介质影响时的情形，也显著不同于前人研究的无变形多孔介质中的相态特征；因而建议在工程应用中，考虑介质变形和界面现象对凝析油气体系相态特征的影响。

The act of Accepting money afterwards entrusted or agreed on beforehand carries the characteristic of the rights-money-deal,which should be undoubtedly regarded as a crime of accepting bribes.But on the other hand,the problem as to whether the act of Accepting money afterwards unentrusted or unagreed on beforehand totally accords with the essence of a...

事前有请托或者有约定的&事后受财&行为具备权钱交易的本质特征，应以受贿罪论处没有争议；但事前既无请托又无约定的&事后受财&行为是否完全符合受贿罪的本质特征，应根据刑法的规定，依照罪刑法定原则，具体情况具体分析。

ANP and CX43 began to express at 2nd week after induction and increased gradually,about 60% of the resulting myogenic cells were positive at 4th week after induction ,they were negative for uninduced cells.hMSCs'surface antigen profiles obtained by Flow Cytometry were negative for CD31\CD34\CD45 before and after induction,but CD90 expressed higher after induction while was weak positive before induction(P.05). Apotosis index was correlated with the cultural time after induction,The apoptosis rate of induced hMSCs was remarkably higher than control group(P.01),and the variation between groups was notable(P.05),the cell cycle analysis showed that the percentages of G_0/G_1phases were reduced significantly after induction. The expresstion levels ofβ-MHC and CTNT mRNA were undetectable before induction,began to increase at 1st、4th week after induction,reached the peak at 6th week and decreased after that,the expression of Bcl-2 and Bax mRNA varied regularly after treated with 5-azacytidine. hMSCs'resting membrane potential、range and rate of depolarization were heightened gradually after being induced.

结果：hMSCs诱导前为纺锤形，诱导后第2天部分细胞即开始发生形变，呈球形或短棒状，1周后胞浆中颗粒增多，约20～30%细胞边缘呈毛刷样变化；hMSCs表面抗原CD31、CD34、CD45在诱导前后差异无统计学意义，CD90未诱导时表达呈弱阳性，诱导后明显增高(P.05)；ANP和CX43在诱导前无表达，诱导后第2周开始表达且表达随时间逐渐增强，但CX43在诱导后第5周表达量开始降低。hMSCs诱导后凋亡指数随诱导后培养时间增加，低浓度诱导组低于标准浓度诱导组，组间差异有统计学意义(P.05)，G_0/G_1期细胞比例诱导后较对照组显著减少(P.05)；β-MHC和CTNT基因分别在诱导后第1周和第4周时表达开始增强，在第6周时均达到高峰，第8周时表达开始衰减，Bcl-2、Bax基因表达呈时间依赖性变化，hMSCs经诱导后随心肌样细胞特征的表达膜静息电位、去极化幅值和去极化速率逐渐增高。
