There were no nick infection, chorioamnionitis and other complications. Eight/sixteen fetal lambs were undergone intro-utero cardiac intervention. The values of body weight and Hct of lambs which were executed. pre-term and full-term delived were (1.77±0.14) kg vs.(2.15±0.23) kg vs.(2.41±0.19) kg and 29%-33% vs. 27%-35% vs. 37%-41%. In autopsy, hydropericardium was found in 4/8 with 1-2.5 mL and 1/8 with 5 mL. Besides 1/8 with interventricular septum centesis injury, there was no centesis damage to endocardium, valve, chordae tendineae, papillary muscles and aortic tunica intima.

Characteristic bands of the resistance gene to powdery mildew Pm21 and Pml3 were found, which could be used in the identification of the disease resistance genes and near isogenic lines.

5发现抗白粉病基因Pm21供体亲本及其近等基因系的特征条带，以及Pm13供体亲本及其近等基因系的特征条带，可用于抗白粉病基因及近等基因系的鉴定。

The fluorescent bands formed in both mesial and distal cementum.Conclusion The results don't support the point that transseptal fibre or force of molar eruption makes teeth migrate mesially; the mesial migration of teeth is related with the reconstruction of alveolar bones and the stress distribution in the bones.

实验结果不支持越隔纤维作用或磨牙萌出力作用引起牙齿近中移动的观点；牙齿近中移动与颌骨内应力分布有关，牙槽骨改建的量与牙齿近中移动量呈正相关。

Both upper and lower dental study models were collected from 30 boys (12 years old) and 30 girls (12 years old) with acceptable normal occlusion to understand the characteristics of the crown size, dental arch width and length such as (1) mesiodistal diameters of crown size from central incisor to first molar,(2) the width and length of dental arch and basal arch and (3) the morphology of dental arch form. After statistical analysis, data were compared with Japanese, Central and South American Indians and North American Caucasians from papers. The results were:(1) There was no statistical difference in teeth size between males and females, except the upper first molar of males was larger than that of females, lower central incisor of males was smaller than that of females.(2) The dimensions of dental arch of males were larger than that of females in general, especially such items as width and length of basal arch.(3) The crown size of Chinese male was in generally smaller than that of four other races, especially the upper canine, lower central incisor and first molar.

为了解住在台湾的中国人其牙齿的大小，齿列弓幅径及形态，为齿科人类学上的特微，以期能对儿童牙科，齿颚矫正科之临床及齿科基础医学能有所贡献，抽取12岁学童男女各30名共60名，可接受为正常咬合之上下颚齿列模型，测量其上下颚(1)左侧正中门牙到第一大臼齿共计12颗恒牙之牙冠近远心径，(2)齿列弓宽径、长径及齿槽基底宽径、长径，(3)齿列弓之形态，以上资料经统计分析作t-test检定，并与诸学者对日本人、北美白人、中美及南美印第安人人种的研究结果作检讨得知；(1)男女性恒牙的近远心径无明显差异，但男性上颚第大臼齿比女性者大，下颚正中门牙比女性者小；(2)男性的齿列弓幅径比女性者为大，尤以齿槽基底宽径及长径最显著；(3)国人男子的牙齿近远心径比其他四人种者为小，特别是国人的上颚犬齿，下颚正中门牙及第一大臼齿最小。

The Fresnel lens in the optical receptor spotlights the headlamp beams to form their image at the 1-meter distance between the optical receptor and headlamps. CMOS camera as an image sensor, takes the photos of their images, which are captured by VG-M201, The application of some digital image processing techniques to these images, such as edge-picking up、 least-square fitting-curve algorithm, is to calculate the offset position/angle of optical axis of the high beams and the nodical offset of the unsymmetrical facular light and shade cut-off line of the low beams.

系统的图像采集工作是利用受光箱中的菲涅耳透镜在1米的测量距离上聚合前照灯灯光，由CMOS摄像头作为图像传感器件，照入灯光远光光斑和非对称近光图像，由嵌入式处理器对捕获的图像运用边缘提取、最小二乘法拟合曲线等数字图像处理技术计算出远光主光轴偏移角度以及非对称近光光斑明暗截止线拐点的偏移，实现了前照灯近光非对称光斑的自动测量。

Bio-Ba/Ti, bio-Ba /Al were chosen as the sensitive markers to show the variation of the biogenic/terrigenous suspended particles in MNLS through the correlation analysis of 12 major elements of the suspended particles. Comparing with the overlain waters, the content of terrigenous particles in the BNL was increased significantly, but was lower than that in the surface sediment.

与上覆水体相比，近底雾状层内陆源组分显著增加，但较底质沉积物为低；生源组分则明显降低，但比底质沉积物为高，这一规律说明底质沉积物再悬浮对近底雾状层有显著的影响，表明Ba_/Ti和Ba_/Al值可以作为近底雾状层颗粒物的高精度示踪指标，其中Ba_/Al值尤为敏感。

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.
