Characteristics and principles of time clustering and frequency with a seismic sequence of more 380 years (1615 —1998) are performed using fractal theory and rescaling range analysis theory. It is concluded that the fiactal dimensions of seismic subset are similar to each other, the mean value is about 0.405, and interval of scale invariance can change 1-2 magnitude order. It is also found that the Hurst index ranges from 0.5412 to 0.5580. The results show that there is of statistical self-similar among different magnitude earthquakes in the area of bridge site.

应用分形理论和R/S分析原理，编写了程序，分析和研究了桥址区的380多年（1615～1998）地震序列的地震时间从集和地震频度特征及规律，得出桥址区不同震级范围的子集合具有近似相等的分维值，约为0.405，子集合无标度区可跨1～2数量级；不同震级层次的地震频度Hurst指数为0.5412～0.5580，都表明了桥址区不同震级层次的地震之间具有统计自相似性。

We found that neither the fusioned nor the non-fusioned forms of Hu-P68 cDNA open reading frame could express efficiently in the E. coli cells; in different prokaryotic expression vectors and under various promotors resulted in no distinctive variations. Deletion of 5'UTR by synthesis adaptors, deletion of 3'UTR or signal peptide sequence by PCR gained no gross improvement. Only the truncated API-I proteins were observed to be highly expressed when the 3'ORF fragment of the Hu-P68 cDNA was fusioned at the 3'end of PAI-I gene.

结果发现无论是以融合形式存在，还是以非融合形式存在，人的P68 cDNA基因在E.coli细胞中都未能获得高效表达：在不同表达载体中，不同启动子对P68 cDNA基因的表达没有显著差异；利用合成Adapter的方法删除5'UTR，及利用PCR技术删除3'UTR和信号肽序列对表达没有明显改善；分别表达被分割的P68 cDNA5'端编码区、中央编码区和3'端编码区均未见有明显表达；当P68 3'端编码区与高效表达蛋白PAI-Ⅰ基因3'末端融合时，仅见有PAI-Ⅰ以截断形式高效表达出来。

The gene-expressionprofile might help to further understand the molecular basis of tube worm physiology.It will also lay a good foundation for functional studies on the adaptation to extremeenvironments and help to make use of them. MicroRNAsare a class of small noncoding RNA that are 20-22nucleotidesand function as regulators of gene expression.

其中，几丁质结合蛋白最具多样性，不仅几丁质酶水解区和几丁质结合区相互独立，而且几丁质结合区也显示丰富的多样性，由不同的几丁质结合区共组成了23种不同的几丁质结合蛋白；EST测序分析中还发现两个溶菌酶基因带有双功能区，可能具有双重功能；此外，肌红蛋白基因也显示了序列的多样性。

Analysis indicates that there is little difference in the displacement of tunnel and well control of stratum displacement by both methods. Plastic zone develops more obviously above the tunnel side by CRD method and is larger by CRD method than by dual sidewall guide pit method. It is comparatively obvious that the plasticity district develops in the side direction of the tunnel by dual sidewall guide pit method and the leading influence distance is also longer than that by CRD method. The development speed of plasticity district is comparatively fast in the range of the leading 3~6 m in CRD tunnel and 0~3 m in sidewall guide pit tunnel. There are different advantages by both methods for passing through sand layer.

结果表明，采用这2种工法时引起的隧道变形相差不是很大，都能较好地控制地层的变形；采用CRD法时产生的塑性区较双侧壁法大，且向隧道侧上方发展较为明显；采用双侧壁法时产生的塑性区在隧道侧向发展较为明显，超前影响的距离也大于CRD法；采用CRD法时的塑性区在超前3~6m的范围内发展速度较快；采用双侧壁法时的塑性区在超前0~3 m的范围内发展速度较快；对于隧道穿越砂层而言，2种工法各有优势。

Busparallel expansion and pipeline technique are adopted to improve the average inputand output speed of recorder based on FLASH memory. 2 A concept of 'cluster' isintroduced. The using state message of each cluster is loaded in the spare area,following the target datum, to keep the pipeline sequence of multiple clusters' loading, which guarantee the average input speed of system. 3 Based on the using statemessage of every cluster, the Cluster Allocation Table established in memory enablethe system to manage the recorder flexibly in high speed, similar to a file managementsystem. 4 PowerPC 8245 based embedded system, along with Vxworks real-timeoperating system is introduced to make the system more easier to be applied to theprojects in the future.

Pure water and acidrain could transform the partial slip regime of steels (45# steel, GCr15 steel and 0Cr18Ni9 stainless steel) to small displacement amplitude, resulting in a wide mixed regime and gross slip regime.

纯净水和酸雨介质改变了三种钢的微动运行区域，使部分滑移区向小位移方向移动，混合区和滑移区变宽：海水使0Cr18Ni9钢的部分滑移区向小位移方向移动，但对45~#和GCr15钢的微动运行区域无明显影响。

At same heights but on different latitude areas, the density of the lower thermosphere is more intense at low latitude than that at high latitude.

在高度相同情况下，中低纬区热层底部的大气密度比高纬区大，卫星受阻也就更大，从而卫星近地点的高度在中低纬区比高纬区要低、白天比夜间低。

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。
