多形态的

Rice agriculture becamethe main subsistence strategy in this phase, the inhabitants were grouped into multi-leveled organizations based on clan unit in the settlement community.

这一时期各聚落都是以农业为主、自给自足的自然经济形态，聚落的社会组织是以氏族为核心的多层次组织结构，聚落内部有分化但并未突破氏族制度，是新石器时代聚落发展的典型形态，因而可称作本地区新石器时代聚落变迁的成熟期。

In this paper, Attacus ricini nuclear polyhedrosis virus was studied. The molecular weight and pi of polyhedrin and structural polypeptides were determined by vertical slab SDS-PAGE and thin-layer isoelectrofocusing electrophoresis. The restriction pattern of ArNPV DNA was assayed by 5 restriction endonucleases.

本文较为系统的研究了蓖麻蚕核型多角体病毒(Attacus ricini nuclear polyhedrosis virus，简称ArNPV)形态特征和生化特性，并预测了多角体蛋白的二级结构，为开发利用蓖麻蚕核型多角体病毒这一生物资源提供了理论参考。

Compared to solvates and salts which are limited to small numbers of nontoxic solvents and ionizable drugs, cocrystals represent a very promising designable solid form of active pharmaceutical ingredients, due to their extensive species and wide application scope.

常见的固体形态如溶剂化物、盐，因为种类少或适用的药物少而在应用上受到一定的限制。所以种类多、适用范围广的共晶作为可设计的药物固体形态近年来逐渐受到关注。

In this work, trially1 isocyanurate and trimethylolpropane trimethaerylate were used as a polyfunetional monomer of PP/PE blends, and the effects of radiation dosage, the kind and amount of polyfunetional monomer on the morphology and mechanical properties were studied.

本研究中采用三烯丙基异腈脲酸酯和三羟甲基丙烷三甲基丙烯酸酯为PP/PE共混体系的多官能团单体。研究了辐照剂量，多官能团单体种类和多官能团单体用量对共混物形态结构及力学性能的影响。

MAIN OUTCOME MEASURES: Morphologic changes of differentiated ventral mesencephalic precursors; Expression of DN-related common marker genes before and after the induced differentiation.

主要观察指标：①多巴胺能前体细胞诱导分化后形态变化。②常见多巴胺能神经元标记基因在诱导分化前后过程中的表达。

Results Myoid/myofibroblastic differentiation occurred most commonly in fibrosarcomatous DFSP. It was recognized histologically as peripherally distributed or randomly scattered small eosinophilic nodules or short bundles, which were composed of bland spindle cells, closely resembling smooth muscle cells or myofibroblasts.

结果 肌样／肌纤维母细胞性分化多出现在纤维肉瘤型DFSP中，表现为肿瘤周边部或肿瘤内散在性分布的深嗜伊红色小结节或短条束，由梭形细胞组成，细胞多无异型性，核分裂象也罕见，形态上似平滑肌细胞或肌纤维母细胞。

The birds of Passeriformes are the group which are the largest number, the most species, the highest station of evolvement and the broadest adaptive radiation of existent aves. The traditional taxonomy were onlyaccording to morphologic and behavioral characters, however their morphologic and behavioral characters are so complicated that we could not differentiate some species easily. Therefore we had some taxonomic research by molecular means in order to supply traditional taxonomy.

雀形目是现存鸟类中种类最多、数量最大的、演化地位最高、适应辐射最广的类群，传统的分类方法仅依据形态和行为特征来划分，但由于该类群的形态及行为特征复杂使得部分种类不易区分，因此有必要依据分子手段研究其系统发生关系、以盼能对经典的分类方法给予补充。

In the present study, the autotetraploid rice IR36-4X was treated with ion implantation technique by nitrogen ion beams and a polyembryonic seedling mutant (named as the IR36-Shuang) was identified in M2 generation. The mutant line was systematically investigated about the location of seedling in polyembryonic seedling, and the cytological initiation of the additional embryo in the 1R36-Shuang was observed and determined.

以低能氮离子束为诱变源，通过对同源四倍体水稻品系&IR36-4X&进行离子注入后在其第2代群体内筛选得到了1株具有多胚苗性状特征的突变株（IR36-双），对该突变株后代的多胚苗形态特征及其多胚来源进行了研究。

The function of bone resorption by MGC was examined with coculture of bone slice and MGC. The resorption lacunae were examined with a scanning electron microscope. The activity of acid phosphatase in MGC was observed by Gomori stain. Results: MGCs showed multinuclei (more than 20 nuclei), irriegular peripheral cytoplasm with pseudopodial projections, vacuoles were seen in the cytoplasm.

用倒置相差显微镜观察体外培养的多核巨细胞的一般形态及降钙素对它的影响；用骨片与多核巨细胞共同培养法观察多核巨细胞的体外骨吸收功能，用扫描电镜观察骨吸收陷窝，Gomori染色观察多核巨细胞的酸性磷酸酶活性。

RESULTS: Olfactory bulb-derived olfactory ensheathing cells adhered to the wall at 24 hours. Olfactory mucosa-derived olfactory ensheathing cells adhered to the wall at 4-5 days. The morphology of the two kinds of cells was similar. Most of them were bipolar and spindle-shaped, and few were tripolar and flat.

结果：体外培养24 h嗅球源性嗅鞘细胞即可贴壁，而嗅黏膜源性嗅鞘细胞多在培养四五天后贴壁，两种来源的嗅鞘细胞形态相似，以双极或梭形细胞为主，少量为3极及多突起形多级细胞，同时夹杂扁平、煎鸡蛋形细胞。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.
