The corrosion fatigue crack growth and near-threshold characteristcsof high tensile steel HT60 were investigated by using the compact specimens underexposure to synthetic sea water. The da/dN vs △K_ relation in air may be conser-vetivel estimated for that in sea water. In the high △K region with high stressratio, owing to the acceleration of crack growth promoted by stress-induced dissol-ution, the crack opening stress intensity factor K_ represents only the result ofcrack surface in contact with corrosion products, so as to give an overestimation ofK_ at crack tip.

对高拉力钢HT60的腐蚀疲劳裂纹扩展特性和门槛值区域特性，采用紧凑拉伸试件在人工海水中进行了实验和研究，结果表明：在空气中的da/dN与ΔK_关系可以作为在海水中的da/dN与ΔK关系的一个偏保守的预测；在高应力比的高ΔK区域，由于应力诱起溶解促进了裂纹扩展的加速；该裂纹开口应力强度因子K_仅反映了裂纹表面同腐蚀生成物接触的结果，从而导致了K_在裂纹尖端的偏大的估计结果。

In contrast, assembly of mobile hard disk, although the manufacturer can also install high-speed hard disk to your hard disk box, but due to the lack of synchronization control chip technology and can not interface with the hard drive to eliminate the bottleneck between the speed, so that assembly of a "high-speed mobile hard disk" can not truly reflect the advantages of high-speed hard drive, it is very easy because the interface with the speed difference between the hard disk, and there waiting for data transmission, data underrun issues.

反观组装移动硬盘，虽然其制造者也能将高速硬盘安装到硬盘盒中，但由于缺乏同步控制芯片技术而不能消除接口与硬盘速度之间的瓶颈，这样组装出来的"高速移动硬盘"并不能真正体现出高速硬盘的优势，倒是很容易因为接口与硬盘之间存在速度差，而出现数据传输等待、数据欠载等问题。

Results The mean sensitivity of the eyes simply with high myopia was (18.39±4.86),similar as the high myopia eyes undetached with the other eye detached (20.28±5.85),and lower than the normal eyes (26.75±4.43),compared with the high myopia eyes o...

结果 高度近视眼颞上、鼻上、鼻下、颞下象限平均光敏感度明显下降，与正常对照组有显著性差异(P =0 。0 0 0 0 )，与视网膜脱离对侧眼—高危眼对照组无统计学意义。

The status quo of high-resolution data acquisition system is discussed and by studying the character of high-resolution seismic exploration and seismic signal, the theoretical models and character of each unit are gained. This paper point out that under 1000 meter's depth where petroleum is embedded the IDR of central controlled seismic instrument and telemetricseismic instrument are lower than 70dB which can't meet the needs of high-resolution seismic exploration.

文章论述了当代高分辨率地震数据采集系统的现状，对高分辨率地震勘探及地震信号特点进行了研究，得出了高分辨率地震勘探数据采集系统的理论模型和各功能单元的理论特性，指出在石油与天然气埋藏的千米以下的地层，集中式数字地震仪和24位遥测地震仪的瞬时动态范围均不超过70dB，远远满足不了高分辨率地震勘探的需要。

Based on the experience and methods summed up by other researchers, the technique of cell culture was employed to study bovine follicular oocytes maturation, fertilization and the development of earlier embryo in vitro. The objective of this research is to upbuild and perfect a set of high-and-new-tech systems to obtain high-yield and high-quality bovine embryo, to provide technical operational regulations and ways and means to embryo engineering in practical production, to accumulate data for theoretical research.
