The result showed that the plant of Maicao No. 9 was tall, with good fecundity, fully filled grain and vigorous growth. The chromosome number of the root cells was 2n=56, through the observation of pollen mother cells meiosis, there were a certain amount of univalents, ring bivalents and bar bivalents in PMCM. Different numbers of lagging chromosomes, chromosome bridges and micronucleus were found in anaphaseⅠ, anaphaseⅡ and tetraspore.

结果表明：麦草9号植株高大，结实性较好，籽粒饱满，生长旺盛；根尖细胞染色体数目为2n=56，对其进行花粉母细胞减数分裂观察，中期Ⅰ具有一定数量的单价体、环状二价体、棒状二价体；后期Ⅰ、后期Ⅱ与四分体时期都出现不同数量的落后染色体、染色体桥、微核等现象。

It is shown that fracture anisotropy results in splitting of converted shear wave and brings wave in transverse component record.

这种转换横波的分裂和快渡偏振方向的定向性难以用各向同性和水平横向各向同性传播来模拟。

Their reliabilities in Chinese subjects were tested. Result: It was found that obsessive-compulsive, avoidant (IPDE: anxious/avoidant), deppendent, histrionic, borderline (IPDE: emotionally unstable), antisocial (IPDE: dissocial), schizoid, paranoid personality disorders had better test-retest reliability, inter-rater reliability, split-half reliability, inter-item consistency.

结果：信度检验显示，强迫型、回避型（IPDE中为焦虑/回避型）、依赖型、表演型、边缘型（IPDE中为情绪不稳定型）、反社会型（IPDE中为社交紊乱型）、分裂样型和偏执型等8个人格障碍分量表的重测信度、评定者信度、分半信度和同质性信度较好；在四个人格障碍检测工具中，IPDE的信度较其它人格障碍工具更好。

The results showed that all of them could detect the presence of ZFY DNA sequences except a 46 XX"male"and a 46 XX hermaphrodite, our findings confirmed that Ferguson-Smith〔1966〕 forwarded the hypothesis that the X-Y intercharge model for XX maleness can be regarded as an abnormal exchange initaited in a region proximal to TDF and extending to the telomere,and,also strongly suggested that ZFY gene palyed an important role in sex determining of human.

结果除一例46XX两性畸形，一例46XX&男性&外，余均能检测到ZFY DNA序列(ZFY DNA序列存在于46XX真两性畸形和45XO Turner's综合症，在国内外尚未见报道)。证实了1966年，Ferguson-Smith提出的理论：在父源减数分裂期间，X-Y发生不等交换，导致Y染色体DNA插入性易位。XX男性是由于Y染色体上的TDF基因转移至X染色体上所致。

Methods:Immunohistochemical technique was used to detect the p21 WAF1/CIP1and P53 protein expressions in:20 usual leiomyoma,70 borderline leiomyoma:including 40 cellular leiomyoma,13 bizarre leiomyoma,4 mitotically active leiomyoma,10 atypical leiomyoma, 3 smooth muscle tumors of uncertain malignant potential and 18 leiomyosarcoma...

应用免疫组织化学法检测 2 0例普通型子宫平滑肌瘤，18例子宫平滑肌肉瘤及 70例交界性子宫平滑肌瘤：包括 4 0例富于细胞型子宫平滑肌瘤、13例奇异型子宫平滑肌瘤、4例核分裂活跃型子宫平滑肌瘤、10例不典型子宫平滑肌瘤及 3例恶性潜能未定型子宫平滑肌瘤的p2 1WAF1/CIP1和P5 3蛋白的表达。

This article reviews and comments on important issues of whether focal attention can be allocated to noncontiguous locations in space, and its relationship with the debates on space-based and object-based attention.

本文整理回顾视觉空间注意力统整与分裂的相关研究文献，并综合评论注意力统整性议题与其选择基础之间的关系。

On low-magnification light microscopy, the specimen had a patternless tissue culture-like appearance with increased mitotic actiity, randomly oriented spindle cells, and extraasated red blood cells (Figure 2B ).

低倍光学显微镜下，标本显示无图案的&组织培养样&表现，伴有有丝分裂活性增高、未定性的梭形细胞和红细胞外渗（图2b），组织病理学所见符合结节性筋膜炎。

The embryogenic cell first divided into multicellular proembryos,then globular embryoid,pearshaped embryoid,long embryoid,scutiform embryoid and mature embryoid.

胚性细胞继续分裂形成多细胞原胚，经球形胚、梨形胚、长形胚、子叶分化期到成熟胚，其发生的胚状体与单子叶合子胚形成具有相似的过程。

VEGF can encourage vascular endothelial cell to divise、propagate、migrate, and add vasopermeability, facilitate producing vascellum sustentaculum, to profit blood supply in ischemic region.

血管内皮生长因子能促进微血管内皮细胞分裂、增殖、迁移，增加血管通透性，促进血管支持物的生成，有利于缺血区血液的供应。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
