器官形成

The primary cambium is found in the stem and root between the phloem and xylem cells, and by division gives rise to the secondary phloem and xylem in woody dicotyledonous plants.

它纵贯于根，茎等器官的木质部和韧皮部之间，是具有分生能力的组织。通过形成层的分裂可以在木本的双子叶植物中形成次生木质部和次生韧皮部。

Results: All flaps survived with primary healing postoperatively. With a follow up ranging from 1-40 months, scars were camouflaged into natural skin tension line. No visible dog-ear, distortion of surrounding skin, or displacement of the anatomical landmarks were observed.

结果：皮瓣全部成活，切口Ⅰ期愈合，随访时间1~40个月，面部形态满意；局邵平整，没有"猫耳朵"形成；切口瘢痕隐藏于鼻唇沟皱褶内而不显；面部各器官没有扭曲和移位畸形。

So the variety of L21 andLainong9217 should be planted in dry land of high yield,and the variety ofLainong8834 and YD27 in dry land of middle yield,and gaining high yieldand high efficiency.2 The researches on the flag leaf and root system senescence after anthesisand yield were studied in dry land wheat of high yield,the activity of super-oxide dismatase and catalase、and the soluble protein content、Cytokinincontent in wheat flag leaf and root system after anthesisand Cytokinincontent in grain decreased slowly,and the content ofmalondiadehydeand the Abscisic Acidcontent in wheat flagleaf and root system and the Abscisic Acidcontent in grain increasedslowly,meanwhile keep higher root vigor and the root vigor decreased slow-ly,the result would be benefit to delay the senescence and gain high yield.3 The effects of soil thickness on the senescence of flag leaf and root sys-tem、nitrogen distribution and utilization and water consumption law andyield in dry land wheat had been studied in soil column and field.

通过大田条件下旱地高产小麦耗水规律及产量变化的研究表明，4个品种耗水量、产量、水分生产率、籽粒产量中来自花后光合器官输送的比例及综合效益评判结果均以鲁麦21和莱农9217为高，而莱农8834和烟D27则与此相反，因而在旱地高产麦田应以种植鲁麦21和莱农9217为主，中产麦田以莱农8834和烟D27为主，以获得高产高效。2在旱地高产大田对鲁麦21与烟D27两品种花后旗叶、根系衰老及产量变化进行了研究，认为花后旗叶与根系SOD、CAT活性、可溶性蛋白质含量、i-PAs含量及籽粒iPAs含量降低缓慢，MDA含量、ABA含量及籽粒ABA含量增加缓慢，同时保持较高的根系活力且下降缓慢，有利于延缓衰老，形成高产。3土层厚度对旱地小麦花后衰老、氮素分配利用及产量的影响进行了研究，随土层厚度加深，根系活力、根系与旗叶SOD、CAT活性及可溶性蛋白质含量增加，MDA含量减少，土层愈薄，其根系与旗叶衰老愈快。

Between the ectoderm and endoderm is mesoderm, which forms the muscles, reproductive organs, blood vessels and excretory organs.

在外胚层和内胚层之间是中胚层，它形成肌肉、生殖腺、血管和排泄器官。

The ampullae join the ducts of two other saclike organs, the seminal vesicles, to form short and straight tubes called ejaculatory ducts.

两侧壶腹分别汇合另外的两个囊状器官——精囊腺的管道，形成短而直的小管，是为射精管。

Type A band was detected in nearly all the organs and tissues,when coat color chimerism was over 85%, indicated the ES cellhas a fairly high potential to differentiate into cells of endoderm, mesoderm and ectoderm,In addition, only type A band was observed in the muscles of 6 mice which coat color chimerism is over 85%,the results indicated that these muscles were differentiated only from ES cells.

当毛色嵌合率大于85%时，几乎所有的器官组织都检测到A型条带，显示了ES细胞在发育形成内、中、外胚层的细胞方面具有很高的分化潜能。另外，在毛色嵌合率大于85%的其中的6只嵌合鼠的肌肉中，只观察到A型的条带，表明这些肌肉只单独来源于ES细胞。

All the organs of his body were working --bowels digesting food, skin renewing itself, nails growing, tissues forming--all toiling away in solemn foolery.

他身上的所有器官都在工作：肠道在消化食物、皮肤在新陈代谢、指甲在生长、各类组织在形成——所有这一切的劳碌此刻仍在进行，即便等着它们的是场一本正经的愚蠢仪式。

This study clearly showed that mosaic variation was caused by chlorophyll deficiency mutation of shoot tip histogen layer-Ⅱ;tissue and organs originated from the layer-Ⅱ couldn't synthetize chlorophyll,thus induced albino; the albino variation appeared yellow green mosaic because layer-Ⅱ was displaced by layer-Ⅲ partly.

研究表明，其变异原因是由于茎尖分生组织的L -Ⅱ组织原层发生失绿突变，致使其衍生的组织和器官不能合成叶绿素，从而形成白化现象；又由于L -Ⅱ与L -Ⅲ组织原层层间发生部分代换，致使白化突变呈黄绿镶嵌的花斑。

The heart is one of first structures to form during organogenesis invertebrate.

心脏是脊椎动物器官发生过程中最早形成的结构之一。

While knowledge is usually considered invisible and abstract, McCulloch realized that knowledge is formed in a physical organ of the body, the brain.

而知识通常被认为是不可见的，是抽象的， Warren McCulloch认识到知识是在人体的一个物理器官中形成的，即大脑。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
