| 1. | Annual mean densities of total phytoplankton in the nine water control zones wczs , 1991 - 2005
一九九一至二零零五年九个不同水质管制区内浮游植物的年平均数pdf |
| 2. | On the other hand , if the mean density of mass - energy is too low , the universe will keep on expanding forever , resulting in an open universe
相反，若质量能量的平均密度太低的话，宇宙会无休止地膨胀下去，成为一个开放的宇宙。 |
| 3. | This effect is seen as a deviation from the uniform hubble expansion of the galaxies and provides a measure of the mean density within the virgo supercluster
这作用被视为背离银河哈勃膨胀的统一而提供对室女座超星系团内平均密度的测量。 |
| 4. | The variation with the time of the mean density of all particles , electron temperature and their space distributions in the discharge cell are calculated in this paper
使用eme模型模拟计算新型荫罩式结构和传统的表面放电式结构，对这两种结构的模拟结果进行比较分析。 |
| 5. | Results did not reveal any significant difference between the two groups of regenerated nerves with respect to the total number , mean density and mean size of myelinated nerve fibers
结果显示：两组的再生有髓神经纤维在总数量，平均密度以及平均直径方面无显著性差异。 |
| 6. | How the universe evolves is affected by three factors , namely the mean density of mass - energy , the space - time curvature and a mysterious factor , the cosmological constant
宇宙尺度的变化受三个因素影响：宇宙中质量-能量的平均密度宇宙的时空曲率与及一个神秘因素宇宙常数。 |
| 7. | The future of the universe is mainly determined by the mean density of mass - energy and the space - time curvature , while cosmological constant does not carry any weight among popular cosmological theories
现在流行的宇宙论都不考虑宇宙常数，宇宙的未来完全由质量能量的平均密度及宇宙的时空曲率来决定。 |
| 8. | Hence , if the mean density of mass - energy is too high , it will ultimately stop the expansion and lead to a closed universe . contraction will follow until the whole universe is squeezed into an infinitely small region
所以，如果质量能量的平均密度太高的话，宇宙是封闭的，膨胀最终会停止下来，然后收缩，最后塌缩成一没有大小的点。 |
| 9. | In the second trial , this modified discontinuous percoll gradient centrifugation method was introduced to isolate spermatids from the semen of fifteen male infertile patients . then the effect was identified by wright - giemsa stain , flow cytometry analysis , immunocytochemistry and fluorescence in situ hybridization ( fish ) . similary , the 22 % percoll fraction contained mostly haploid cells [ ( 91 . 85 ? 5 . 18 ) % ] ( p < 0 . 005 ) and the mean density in this fraction was ( 1 . 010 ? 0 . 786 ) x 105 / ml
C法，对15例各种类型不育患者的精液细胞进行分离，并利用瑞姬染色法、流式细胞术、免疫细胞化学和荧光原位杂交oisffi等方法，从细胞形态特征、 dna倍体、细胞表面标i己与分化抗原，以及原位杂交信号的数目和位置结合细胞核特有的形态等方面加以鉴定。 |
