For Goupitan Hydropwer Station on Wujiang River,over 1 200 anti-uplift anchor pile s are arranged in the water cushion pool to anchor the non-uniform soft rock strata composed of shale,clay rock,silty clay rock,thin layer of marlite and less medium-fine calcareous sandstones etc.

乌江构皮滩水电站水垫塘部位布置了1200多根抗浮锚桩，对页岩、粘土岩、粉砂质粘土岩，及夹薄层泥灰岩和少量中细粒钙质砂岩等不均质软岩层软岩进行锚固，原设计锚桩的间距为2.2m，为了优化设计，缩短工期，在施工前进行了4根锚桩原位抗拔试验，根据锚桩在抗拔过程中周边一定范围内岩体变形沿径向的分布规律，及破坏时裂隙的扩展形态和范围，确定了锚桩的间距，在此基础上提出了锚桩间距的优化方案，并应用于工程施工。

The signals look like noncontinuous beads on the DNA fiber,which consist of multi-copy and arrange tandemly.Fiber-FISH results with 45S rDNA probe showed that an average signal length is about 3～11μm in many tandem copy sequence(measure number,n=8),so we estimated the size of each copy to be approximately 11～30kb in cotton genome.There are dual signals on each end of the mitosis metaphase chromosomes and pachytene chromosomes hybridized with telomere DNA probe.The signals also look like non-continuous beads on the DNA fiber,the length is about 1～9μm,so we estimated the size is about 4～27kb.The signals almost covered the whole mitosis metaphase chromosomes and pachytene chromosomes of G.arboretum Shixiya 1 hybridized with gDNA probe,the euchromatin zone and heterochromatin zone were identified clearly on pachytene chromosomes,and the signals also look like non-continuous beads.Two BAC clones 150-D-24 and 182-F-9 in DNA BAC library of Pima90 were selected as probe to hybridize with mitosis metaphase chromosomes,pachytene chromosomes and DNA fiber of G.raimondii.

棉花FISH技术系统的应用研究。45S rDNA在亚洲棉石系亚1号中期和粗线期染色体上有两对大的信号，在DNA纤维上信号为非连续的念珠状，多个拷贝串联排列，每个拷贝长度大约在3～11μm，推测每个拷贝的实际长度为11～30kb；端粒序列在亚洲棉石系亚1号中期和粗线期染色体端部都有双点信号，在DNA纤维上信号也为非连续的念珠状，不同染色体上信号长度大约在1～9μm不等，推测实际长度为4～27kb；gDNA信号几乎布满整个亚洲棉石系亚1号中期和粗线期染色体，在粗线期染色体上能明显区分出常染色质区和异染色质区，DNA纤维上的信号均为非连续的念珠状。

Finally the application of the homemade ODS for MSPD and the economical availability of the product was evaluated. Results show as the following: 1. It is a simple method for the preparation of a bonded octadecyl phase which has large particle and high extent of coverage of the bonded phase.
