Subsequently, the tapetum cell began to disorganize, and it kept the strongest Ca^2＋ fluorescence intensity from microspore to pollen maturity until the tapetum was disappeared completely.

在花药壁组织内Ca^2＋分布也呈现规律性的变化：造孢组织时期，花药壁组织Ca^2＋荧光强度在不同壁层组织中分布均匀；小孢子母细胞时期，药壁中层细胞Ca^2＋荧光最强，绒毡层细胞次之；单核小孢子时期，绒毡层细胞呈解体状态，Ca^2＋荧光最强，并保持到二核花粉时期直至绒毡层完全消失，但此时花药纤维层发育形成，表现出较强的Ca^2＋荧光。

The anther possesses four microsparangia with its wall composed of four layers: epidermis, endothecium, middle layers and a 2\|nucleate celled tapetum.

绒毡层细胞在发育后期由单核分裂为2 核，多原位解体，为腺质型；但大约有12％小孢子囊的绒毡层在小孢子四分体释放时期进入花药室内，成为变形绒毡层。

Results In the medium and high dose F0 groups, it was observed that the atrophy and incrassation of seminiferous tubule, decrease of spermatogenesis, hyperplasia of interstitial tissue, especially in high dose groups spermatozoon abnormality and nucleolus concentration in the rats testis after DU ingestion for 14 months. The changes became more severe with the prolongation of DU ingestion. Such changes occurred in filial rats (F1) after DC ingestion for 5 months. In the medium and high dose F0 groups, it was observed that a little atrophy of kidney glomerulus, hyperplasia of interstitial tissue after DC ingestion for 14 months, and kidney glomerulus fibrosis happened after DC ingestion for 20 months, such changes occurred in filial rats (F1) after DC ingestion for 5 months In the medium and high dose F0 groups, splenic germinal center and periarterial lymphatic sheaths were hyperplasia , companies with lymphopoiesis after DC ingestion for 7 months, splenic white pulp became more small and sparse after DC ingestion for 20 months.

结果 F0代的中、高剂量组大鼠摄入贫铀14个月后可见雄性的精曲小管萎缩，管壁增厚呈空虚网状，生精细胞层次减少，间质细胞增生，但仍见有精子生成；高剂量组可见到精子呈异型性改变，细胞核浓缩深染，且随着摄入时间延长改变愈趋明显；F1代大鼠摄入贫铀5个月后就有上述改变且更为严重。F0代中、高剂量组大鼠摄入贫铀14个月后肾小球轻度萎缩，间质增生明显，20个月时肾小球萎缩纤维化；F1代大鼠摄入贫铀5个月后就有上述改变。F0代中、高剂量组摄入贫铀7个月时脾脏生发中心和淋巴鞘增生，淋巴母细胞增生活跃，20个月时脾小体减少，生发中心稀疏；F1代大鼠摄入贫铀早期和晚期有类似改变。F0和F1代高剂量组摄入贫铀早期肝脏有炎症细胞浸润，晚期骨髓有核细胞减少，脂肪细胞增加。

So, the nucleocytoplasmic ratio decreased. 10^(-5)MATRA significantly suppressed the proliferation of os732 with only 39.5% cells when compared with untreated cells. Cells in G1 phase increased significantly, and the number of S phase decreased. Expressions of cy-clinD1, cycimD2 and CDK4 mRNA declined, especially cyclinD2 and CDK However, expressions of cyclinD3 and P21WAF1 mRNA changed little.

结果 ATRA作用后，OS732细胞胞浆展开，细胞核变小，核浆比例变小；瘤细胞生长减慢，细胞计数为正常对照组的39.5%； G0/G1期细胞明显增多，S期细胞减少，细胞阻滞于G0/G1期；CyclinD1、CyclinD2、CDK4mRNA表达均下降，尤以CylinD2、CDK4下降最明显，CyclinD3、P21WAF1mRNA未见明显改变。

No primitive blood cells were observed in liver, which implies that the liver was not the hemopoietic organ in C. mydas. The development of erythrocytes includes 5 stages: primitive, early, middle, late, and mature. The body sizes of these cells increased first, then decreased, and increased in the end. The development of granulocytes includes 5 stages also: myeloblast, promyelocyte, meddle immature granulocytes, late immature granulocytes, and mature granulocytes. The body sizes of them decreased; and the sublobe of the nuclear may indicate the aging.

红血细胞的发育经历了5个阶段：原红血细胞、早幼红血细胞、中幼红细胞、晚幼红血细胞和红血细胞等阶段，其胞体体积经历了由小到大，由大到小、再到大的发育过程；粒细胞的发育经历了5个阶段：原粒细胞、早幼粒细胞、中幼白细胞、晚幼白血细胞和白细胞等阶段，胞体体积均由大到小变化，核分叶可能是粒细胞的衰老的标志；淋巴细胞和单核细胞的发育各经历了3个阶段。

In small batch bulk PP/ nucleator system, The nucleator TMB-5 was used as the impact modification for different small batch bulk PP045 and PP075 in the second part of the project.

通过XRD分析表明，β成核剂TMB—5的加入使小本体PP的结晶度提高，并对β-PP有诱导生成作用，同时发现对小本体075具有较好的增韧效果，但使其强度有所下降。

FCC-SDP is composed of multi-banks of low capacity scratchpad memory modules, equipped with a synchronization framework based on hardware signal lamps, and supports parallel accessing of multi-DSP cores and point to point events synchronization.

FCC-SDP以多体并行的小容量便笺存储器为传输媒介，采用基于硬件信号灯的同步机制，支持多个DSP核的并行访问和点对点事件同步，访问速度与一级数据Cache相当，能够快速实现DSP核间细粒度共享数据的传输。

Karyotype formula of Gossypium hirsutum L.was 2n=4s=52=30m+20m (4SAT)+2st (2SAT); and its absolute lengths of chromosomes averaged 3.40μm; arm ratio differed from 1.24 to 4.02,with the mean value of 1.77; three pairs of satellite chromosomes; the ratio of the longest to the shortest chromosomes was 2.36; and the karyotype belonged to 2B in Stebbin's classification.

陆地棉的核型公式为2n=4x=52=30m+20sm(4SAT)+2st(2SAT)；染色体绝对长度平均3.40μm；臂比值最大与最小的分别是4.02和1.14，平均1.77；随体3对，分别位于第12、19和26对同源染色体的短臂上；最长与最短染色体的比值为2.36；其核型属于Stebbin的2B类型。
