He teliospore morphology of TCK and TCT is so siminar that it is difficult to distinguish, and then accurate identification methodology of the TCK and TCT is high priority for desease quarantine.

CK与TCT的孢子形态学上非常相似，极难分辨。因此能否精确鉴定这两种腥黑穗病菌对于顺利完成检疫工作都是至关重要的。

Software and results were saved in EXCEL for consequent statistic operation and obtaining chromosome patterns. 4 indexes were chose, such as chromosome karyotype, C-band pattern, chromosome behavior and B chromosome for comparative analyses, and adopted SPSS to reconstruct dendrogram. Combined with studies on insect morphology and insect geography, we made a detailed analysis and speculation on the relationship of taxa concerned. Finally we got the conclusions as follows: 1. The number of chromosomes in grasshoppers of Oedipodiae is 2n 〓=23=22+XO. All chromosomes are telocentric chromosomes. Most of the genome formulas are 3L+6M+2S+X and 3

论文选取染色体核型、C-带带型、染色体行为和B染色体这4个方面的指标进行比较分析，运用SPSS系统分析软件建立表达各属和各种之间亲缘关系的系统树，并结合昆虫形态学和昆虫地理学等方面的研究成果，对其亲缘关系进行了比较详细的分析和推测，得出以下结论：一、斑翅蝗科蝗虫的染色体数目都稳定在2n〓=23条，性别决定机制是XO型，染色体均为端部着丝粒，染色体组式以3L+6M+2S+X和3L+7M+1S+X这两种类型为主，即3对大型染色体，6～7对中型染色体和2～3对小型染色体，X染色体以中型为主，在染色体组中主要排列为4～7位。

METHODS 1、Rat Tenon's capsule fibroblasts were cultured from tissue plants.

1。采用植块培养法培养大鼠Tenon's囊成纤维细胞，并对其进行形态学及免疫组化鉴定。

Finally, combining PDE with Differential Geometry, parametrically representing the surface, tensor based image processing techniques have been proposed, such as edge detection , morphological operation? implicitly representing the surface as the level-set of the higher dimensional function, the variational problems and partial differential equations that define maps onto the given generic surface have been discussed.

本文结合微分几何学，基于曲线坐标系下的微分算子将平面上的图像处理框架推广到曲面上，得到了参数化曲面上的图像处理框架，并给出了边缘检测和形态学运算的算例；在已知给定曲面的隐式表达时，探讨了定义在任意曲面上的偏微分方程，解决了任意曲面上数据场的扩散问题。

Agarose gel electro- phoresis showed typical DNA ladders. These findings suggest that CP-induced apoptosis and/or cell death be involved in teratogenesis.

电镜观察所显示的细胞凋亡的形态学变化及DNA琼脂糖凝胶电泳的结果均提示CP致畸作用可能与其诱导的细胞凋亡有关。

We studied the optimum medium and hormone combination of callus induction from cotyledons, subculture of callus, shoot regeneration from callus, shoot-extension induction, root induction and identified the chromosome number of the plantlet. The results showed that: MS+2,4-D 2.0mg/L+KT 0.5mg/L, MS＋2,4-D 2.5mg/L＋KT 0.5mg/L, MS+2,4-D 0+KT 1.0mg/L, MS+KT 0.5 mg/L and basal MS medium. One plantlet among twenty two was determined as a tetraploidy based on the plant morphology, observation of the leaf stoma and chromosome number of the root, other two plantlets represented morphological variation.

结果表明，诱导章丘大葱子叶产生愈伤组织、愈伤组织的继代培养、愈伤组织芽分化、芽点的伸长及诱导生根的最佳培养基及激素配比分别为：MS+2，4-D 2.0mg/L+KT 0.5mg/L、MS＋2，4-D 2.5mg/L＋KT 0.5mg/L、MS+2，4-D 0+KT 1.0mg/L、MS+KT 0.5mg/L和MS基本培养基；试管苗经驯化移栽后，共有22株成活，成活率为92%，对成活的再生植株进行形态学、叶片气孔及根尖染色体鉴定表明，共有3株发生变异，其中2株为外部形态上的变异，而另一株为染色体的加倍变异。

The cell phenotype was observed at 6,12,24 and 48h and the cellular proliferation was examined by methyl thiazolyl tetrazolium method.

将幽门螺杆菌野生株与cagA基因缺失突变株与BGC823细胞共培养，分别在6，12，24和48h观察细胞形态学变化，采用四甲基偶氮噻唑蓝比色法检测细胞增殖活性，流式细胞仪检测细胞凋亡情况。

Thereinafter, I will introduce on the road movie as an independent morphology to discuss its characteristic better and more roundly, and to make it break away from its embarrass status in such a long period.

本文试图将"在路上"电影作为一个独立的形态学的概念提出，更全面、更准确地探讨其形态特征，从而使其摆脱长期处于边缘地位的尴尬立场。

Recently, with the development of imaging technology, three-dimensional reconstruction has been applied in the study of tooth anatomy, especially, root canal morphology.

近年来，随着影像学技术的发展，三维影像重建技术已开始应用于牙齿解剖形态的研究，尤其是根管形态学研究。

AIM To explore the effects of infrasound on auditory thresh old and morphology of cochlear hair cells in guinea pigs.

目的 观察慢性次声暴露对豚鼠听阈及耳蜗毛细胞形态学的影响和作用特点。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
