It indicated that not only can Spirulina cells grow photoautotrophically and photomixtrotrophically, but also can grow heterotroph ically under some specific conditions. light intensity, light quality, temperature, species and concentration of metals, rare

认为螺旋藻细胞不但能进行光合自养和混合营养生长，而且在某些特定的环境条件下，还能进行异养生长；光照强度、光质、温度、金属元素、稀土元素、盐度、藻体细胞浓度、溶氧水平、维生素、激素和磁场等环境因素对螺旋藻细胞的光合性能和细胞产率都有显著影响。

The experimental results revealed that 60% of cell decay in a nitrifying system was caused by activity decrease and 40% was caused by cell death. In a heterotrophic system, however, activity decrease was responsible for 80% of cell decay, and the other cell decay for 20% was caused by cell death.

结果表明，硝化系统细菌在衰减过程中由细胞活性降低引起的衰减约占60%，由细胞死亡引起的衰减约占40%；而在异养系统中由活性降低引起的衰减和由细胞死亡引起的衰减分别为80%和20%。

Results There were characteristic changes in cartilaginous tissue in OA, such as rough cartilaginous surface, irregular arrangement, decrease in number, degeneration and necrosis of chondrocyte, and cell cluster existed. The thickness and groundsubstance of cartilage in OA was thinning and uneven, and metachromatism could be seen.

结果 OA软骨组织表面粗糙不平，软骨细胞排列紊乱，数目减少，有细胞成簇现象，可见软骨细胞变性、坏死，软骨厚度变薄，基质染色不均匀，有异染性。

F1 hybrid has the morphological feature which is between the male and female parents and shoed strong heterosis, exuberant vitality, late ripe period and low rate of self-fertility. The average chromosome configuration of F1 in PMC MI was 18.58Ⅰ+18.59Ⅱ+0.085Ⅲ+0.028Ⅳ. At anphase Ⅰ in PMC, some laggard chromosomes arranged in equatorial plate. Micronucleus and a lot of abnormal cells can be observed at dyad, tetrad and microspore.

杂种F1形态特征介于双亲之间，具有较强的杂种优势，生长旺盛，熟期晚，自交结实率较低。F1花粉母细胞减数分裂中期Ⅰ平均染色体构型为18.58Ⅰ+18.59Ⅱ+0.085Ⅲ+0.028Ⅳ，PMC后期Ⅰ观察到部分落后染色体排列在赤道板上；二分体、四分体和小孢子时期，细胞内普遍观察到微核，且出现大量异形细胞。

FUNGI Fungi are almost entirely multicellular, heterotrophic (deriving their energy from another organism, whether alive or dead), and usually having some cells with two nuclei multinucleate, as opposed to the more common one, or uninucleate per cell.

FUNGI Fungi是几乎完全地多细胞性，异养(获得他们的能量从另一个有机体，是否活或死)和通常有与二个中坚力量的有些细胞多核，与更加共同一个相对或者单核每个细胞。

Self-pollination was brought as the essential reason for causing emptied seeds by former researchers. Based on those studies, potassium antimonate and electron microscopy were used to study the calcium distribution of pollens in the micropylar canal of self-pollinated and cross-pollinated ovules and morphological changes in certain cells undergoing programmed cell death from pollination to fertilization, and observation of histo-chemical changes during microgametopyte development was performed by paraffin section.

前人研究认为自交是华北落叶松产生空粒的主要原因，本论文在此基础，运用焦锑酸钾沉淀法配合电镜观察研究了传粉后到受精前异交控制和自交辅助授粉胚珠珠孔道内花粉的钙分布情况，及此过程中细胞程序化死亡超微结构的变化，并通过石蜡切片研究了华北落叶松传粉后到受精前雌配子体发育过程及细胞内含物的变化，以研究在受精前胚珠内是否存在花粉识别与选择系统，探讨钙信号传导和花粉与胚珠相互作用及细胞程序化死亡的关系。

The results show:the above two species of Flos lonicerae's palisade parenchyma are composed of 1 layer of cylindrical cells.But in karst areas variety palisade parenchyma is cylindrical cells .Palisade and spongy tissue have distinctly differentiation.,are both bifacial leaf.

研究结果表明：以上2种金银花栅栏组织的层数均为一层，有栅栏组织和海绵组织的分化，均为异面叶；但岩溶地区的栅栏细胞为圆柱形，非岩溶地区的栅栏细胞为长柱形；岩溶地区品种的上下表皮细胞明显比非岩溶地区的品种大，并且其栅栏组织和海绵组织的排列较非岩溶地区品种紧密；气孔都仅分布在下表皮，气孔类型为肾形，岩溶地区气孔密度大。

Morphology of sexual reproduction abortion in'High Noon', a distant hybridization cultivar of tree peonies(P.delavayi var. lutea×P. suffruticasa), was systematically investigated with light microscopy and cross. The results indicated that:(1)The stamens matured earlier than the gynoecia and pollens dispersed at the early stage of anthesis but the rate of normal 2-celled pollens were merely 2.41%.

采用光镜和杂交等方法对牡丹远缘杂交一代品种'正午'有性生殖败育进行系统形态学观察发现：(1)雄蕊较雌蕊先成熟，初花期即散粉，正常2-细胞花粉仅占2·41%，且花粉在多种培养液中、在自身和其它两种柱头上均不萌发；柱头在谢花期大量分泌粘液，进入最佳授粉状态；(2)同一胚珠中多个大孢子母细胞减数分裂高度不同步，胚囊发育与受精延迟，部分胚乳游离核在细胞化时期分裂异常；(3)自花及品种内异花授粉不结实，天然授粉结实率为0·053‰~0·130‰。

The shortage of this way was that feeder cells could be passaged together with hESCConclusion HAFi could replace MEF as feeder layer to support the long-term culture oftwo Chinese human embryonic stem cell lines. This could remove the cells of animal originand heterogenetic pollution in the culture system. It also reduced the culture of primarycells and solved the instability caused by different batches of primary cells.

结论HAFi细胞可以用做两株中国人胚胎干细胞培养的饲养层，取代MEF后解决了动物源性细胞混杂和异源污染问题，省却了饲养层原代细胞的培养步骤同时解决了由不同批次饲养层差异带来的培养体系的不稳定。
