It indicates that the different parts of the cattle-egg stone samples in different colours all mainly compose of pyrophyllite, coexisted by two kinds of polytype of monoclinic and triclinic pyrophyllite, and the average crystal structural formula is Al4.04 Si7.89 Al0.11O204. The aggregation of pyrophyllite arranges with no direction, and the crystal size of the single pyrophyllite crystal in the weathering skin is a little bigger than that in the basal part.

The survival rates of CEM cells cultured with cis-diamminedichicloroplatinum added 24 h later were higher than that cultured with hTERT ASODN and DDP added 24 h later. The survival rates of CEM cells cultured with DDP were similar with that cultured with hTERT SOND and DDP. In morphological observation of apoptotic cells using Giemsa staining, cells treated with DDP or DDP combined with hTERT ASODN ro SODN at 48 h, displayed classic apoptotic changes. Apoptosis rates of CEM cells treated with DDP for 48 h after 24 h of exposure to ASODN significantly increased. There was significant difference in the percentage of apoptotic cells of CEM cells between hTERT ASODN plus DDP and SODN plus DDP or DDP alone, respectively.

The aortic diameter change rates were (-0.2±1.4) mm/year and (-0.18±0.98) mm/year in aortic diameter0 mm group and≥40 mm group, respectively. There was no significant difference between the two groups. The ascending aortic diameter change rates were (0.8±1.6) mm/year in BAV group, and (-0.3±1.5) mm/year in TAV group. The ascending aortic diameter of patients in BAV group enlarged continuously following AVR.

The experimental and numerical results show that secondary flow can be restrained by endwall boundary layer suction and the restraining mechanisms of endwall suctions in different locations are different from each other.

同时建立了可研究端壁边界层抽吸对叶栅气动特性影响的实验系统，分别对无抽吸工况和存在抽吸工况的叶栅出口流场和气动特性进行测量，并采用流动可视化技术显示叶栅壁面附近的流动图谱。

Compared with progenies of inter-tree-pollinated E.urophyllaagain,progenies of self-pollinated E.urophylla showsignificant inbreeding depression in height,DBH and volume;theyshow no significant inbreeding depression in water content ofgreen wood,basic density and bark thickness;their content of1%NaOH extractives increases significantly,and their maturefiber length decreases significantly.

与尾叶桉株间杂交子代比较，尾叶桉自交子代的树高、胸径和材积具有显著至极显著的近交退化，生材含水率、木材基本密度和树皮厚度无近交退化现象，1％NaOH抽提物含量呈略显著性提高，成熟材纤维长度呈显著性减短；尾叶桉自由授粉子代的近交退化规律大致与自交子代相同，但其退化程度远不及自交子代。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
