种差异

Leaf epidermis of 35 species of Ormosia in China was examined under light microscope andscanning electron microscope. The epidermal cells of both upper and lower leaf surfaces are polygonal or irregular in shape, anticlinal walls are straight, arched, sinuolate or sinuate, and stomata are elliptic or ovate.

用光学显微镜和扫描电子显微镜观察了红豆属35种的叶表皮形态，这些植物的叶上下表皮细胞为不规则形或多边形，垂周壁有平直、弓形、浅波状或深波状，表皮细胞形状和垂周壁在种间有一些差异。

Our results show that there were no significant difference in insect species and abundance between the massion pine forest and the slash pine forest.

通过对6种不同林分结构下的马尾松林和湿地松林内昆虫群落调查与多样性指数分析，表明2种松树内的昆虫种类和数量无显著差异，混交林中的昆虫群落的种类和数量比纯林多，尤其以捕食天敌类群的种类和数量更为明显。

Accordingto the difference of HA gene,which is separated 15 stype from H1 to H15;according to difference ofNA gene,which is separated 9 stype from N1 to N9.It is no cross-reaction between different HA orNA,so it is diffcult to detective.

根据流感病毒的血凝素和神经氨酸酶的抗原性差异，可将A型流感病毒分为不同的亚型，A型禽流感病毒的HA已发现16种，NA有9种，不同的H抗原或N抗原之间无交叉反应，给该病的防制带来了极大的困难。

Especially,the subbranch of enterobacteriaceace made again four small branches as genus taxon.This tree also shows that bacilliform bacterium is distinct from each other in the NJ and MP trees.After all species on the tree are merged,the topological configuration of the unrooted tree of 16S gene is closed to that of the host range unrooted tree.However,the position of bacillus is greatly changed on both the unrooted trees.

将16S DNA的NJ树隐去所有的种，以属为单位所得到的以分枝形式的无根树在拓扑结构上与菌群分布含量所构建的无根树相近，但芽孢杆菌在两种无根树的位置中有较大的差异。

IL-1βmRNA expression in the developmental brain in Wistar rat: IL-1β mRNA in hippocampus, cerebral cortex and subcortex was detected by postnatal day 1 and gradually increased with development, reached a peak at postnatal day 21, and then gradually decreased to lower level at adult; In P77PMC rat, IL-1β mRNA expression was similar to Wistar rat before postnatal day 14, then gradually increased and surpassed Wistar rat at postnatal day 28, reached a peak in adult.

原位杂交显示谷氨酸诱导Wistar大鼠惊厥和P77PMC大鼠听源性惊厥后脑内IL-1βmRNA表达情况。结果发现，两种不同惊厥模型大鼠惊厥后脑内IL-1βmRNA表达存在明显的差异。谷氨酸引起惊厥诱导脑内皮层、海马和丘脑IL-1βmRNA表达增高的程度远较P77PMC大鼠听源性惊厥为低，而且惊厥后IL-1βmRNA表达增加较慢，于4-8h达高峰，而听源性惊厥可于惊厥后2h迅速达高峰。但两种形式惊厥诱导脑内IL-1βmRNA表达最高的部位均是海马。

The species of green and brown algae found in the intertidal were mainly warm t emperate , those of red algae were more varied, however, including warm temperate , temperate and subtropic as well as cold temperate species. There existed signi ficant difference in species dominance among the four seasonal communities.

绿藻和褐藻类群主要为暖温性种类，而红藻类群比较复杂，即有暖温带性的、温带和暖水性种类，也有寒温带的冷水性种类。4个季节群落的物种优势度序列存在明显的差异，海黍子在春季和冬季为群落的第1优势种，而孔石莼在夏季和秋季为第1优势种。

However, Most vector-based algorithms of computing the Voronoi diagrams have difficulty while dealing with complex generators , and so author first discusses the properties of Voronoi diagram based on the Manhattan distance or supremum distance, the experimental result shows that Voronoi diagram based on the Manhattan distance or supremum distance or alternatively using these two distances is a rough approximation of Euclidean-metric Voronoi diagram.

鉴于构建Voronoi图的矢量方法存在一些问题及不足，首先分析了基于曼哈顿距离和上限距离的Voronoi图性质，进行了相应的实验，实验结果表明基于这两种距离或交替使用这两种距离所产生的Voronoi图与基于欧氏距离产生的Voronoi图之间存在较大的差异，属于精度较差的逼近方法。

The results showed that both CDV strains could induce apoptosis of infected cells. However, there was significant difference in the percentage of apoptotic cells between the two strains (P＜0.01). The strain resulted in the CPE type of cell-rounding induced much higher ratio of apoptotic cells than the strain resulted in the CPE type of syncytium.

结果发现，2种毒株感染引起的细胞病变类型不同，分为圆缩型与合胞体型；2种毒株均可诱导感染细胞凋亡，但毒株间的凋亡细胞比例存在差异，即产生合胞体型细胞病变的毒株凋亡出现较晚，凋亡细胞比例显著低于产生圆缩型细胞病变的毒株(P＜0.01)。

比较是把两种或两种以上的事物进行比较，以辨别出它们的相似之处；对比是将这些事物进行对照，辨别其差异而指出各自的特征和本质。

So when we felt another kind of tetra-dimensional, extreme, music-like art made up of colors and lines in Malevich and Tatlin's experiment in the early of last century, people had to get used to the visional format from Kandinsky, Pollock, Mondrian and Roscoe. The brand-new artistic experiment is further rooted into experience of our religion, music, philosophy, life and other staffs not only from format to content, but also from theory to techniques. And the traditional plane paintings are used to annotate the art meaning of non-representation. But Chinese are unwilling. It is only the format product of powerful culture in expanding, rather that there are lots of differences between the western abstract and oriental "image".

所以当我们从上个世纪初在马列维奇、塔特林的实验中，体验到一种被称为四度的、极致的、音乐似的、或者说将色彩和线编制成为另一种艺术自由的端倪时，人们就不得不习惯由康定斯基、波洛克、蒙德里安和罗斯科所带给我们的视觉图式，它们从形式到内容、从理论到技巧，无不变本加厉地把这种全新的艺术实验根植于我们对宗教、音乐、哲学、生活以及诸多问题的体验中，并用传统的二维平面绘画来诠释出非具象的艺术意义，不过这些对中国人来说，很可能是不情愿的，它只是强势文化在扩张中的样式产物，更何况这些西方式的抽象与东方式的"意象"仍然有着极大的差异。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
