我们通过卵形弹丸侵彻无约束抗压强度名义值为１４ＭＰａ、３５ＭＰａ和９７ＭＰａ的混凝土靶体试验，来研究、处理侵彻试验的侵深。根据我们的试验数据和Ｃａｎｆｉｅｌｄ与Ｃｌａｔｏｒ提供的试验数据，我们推导出了一个卵形弹丸侵彻混凝土靶（正碰）的侵深计算经验公式。公式中包括一个单独的无量纲经验常数，该常数仅取决于靶体的抚约束抗压强度。我们通过对着速在２５０￣８００ｍ／ｓ范围内的六组侵彻数据中侵深与着速的分析、

Nanostructure fabrication from block copolymers in my group normally involves polymer design, synthesis, self-assembly, selective domain crosslinking, and sometimes selective domain removal. Preparation of thin films withnanochannels was used to illustrate the strategy we took. In this particular case, a linear triblock copolymer polyisoprenc-block-poly(2-cinnamoylethyl methacrylate)-block-poly(t-butyl acrylate), PI-b-PCEMA-b-PtBA, was used. Films, 25 to50 μm thick, were prepared from casting on glass slides a toluene solution of PI-b-PCEMA-b-PtBA and PtBA homopolymer,hPtBA, where hPtBA is shorter than the PtBA block. At the hPtBA mass faction of 20% relative to the triblock or the totalPtBA (hPtBA and PtBA block) volume fraction of 0.44, hPtBA and PtBA formed a seemingly continuous phase in the matrixof PCEMA and Pl. Such a block segregation pattern was locked in by photocrosslinking the PCEMA domain. Nanochannelswere formed by extracting out hPtBA with solvent. Alternatively. larger channels were obtained from extracting out hPtBAand hydrolyzing the t-butyl groups of the PtBA block. Such membranes were not liquid permeable but had gas permeabilityconstants ～6 orders of magnitude higher than that of low-density polyethylene films.

Background: The difficulty of learning curve in different microsurgical regions is one of the most challenging factors that affect neurosurgeon’s life. Two of the delicate areas are the suprasellar intraventricular and pontocerebellar region. High level of microsurgery or endoscopic surgery requires virtuosity, which can not be learnt only by assisting. Even among the well skilled neurosurgeons who work in big centers we can often hear “in spite of centralization there are not enough operations available to keep the high level of our skills”. The situation of surgeons working at mid centers is more difficult especially on duties. Methods: Huge number of scientific articles demonstrate the importance of different types of cadaver practice, but always did not pay enough attention to the daily fast fresh cadaver exercises. Focusing on lifelong every day practice we examined the difficulties of learning curve in intraventricular and pontocerebellar region and try to give some useful advice for practicing on fresh cadavers on a daily basis. We offer a simple endovascular fresh cadaver model for practicing. Results: We have performed more than 800 quick (60 - 90 minutes long) routine practice sessions in these two regions during last 18 years. We found that implantation a modelized pathology and removing it by microscopical or endoscopic way without causing injuries to sensitive structures seems to be the most practical way of fast everyday training. Nerves and vascular bypass sutures are also excellent practical method. Conclusions: We have focused on daily fast fresh cadaver practice as a novel training method like used in professional sport and art. After 18 years experience we can state that, for mastering the microsurgery of pontocerebellar and intraventricular region, which is one of the most challenging regions minimum 100 fresh cadaver practice sessions need before performing the operation. We believe this region should be part of fast fresh cadaver microsurgical

A karyotype of Trifolium repens constructed from mitotic cells revealed 13 pairs of metacentric and 3 pairs of submetacentric chromosomes including a pair of satellites located at the end of the short arm of chromosome 16.C-bands were identified around the centromeric regions of 8 pairs of chromosomes. A 350 bp tandemly repeated DNA sequence from T. repens labelled with digoxygenin hybridized to the proximal centromeric regions of 12 chromosome pairs. Some correlation between the distribution of the repeat sequence and the distribution of C-banding was demonstrated.
