＜正＞Recently,various features for content-based image retrieval（CBIR） have been proposed,such as texture, color,shape,and spatial *** this paper we propose a new feature,called orientation-distance histogram for CBIR. Firstly,we transform the RGB color model of a given image to the hSI color model and detect edge points by using the h-vector ***,we evaluate the orientation-distance histogram from the edge points to form a feature *** normalization of feature,our proposed method can cope with most problems of variations in image. Finally,we show some results of query for real life images with the precision and recall rates to measure the *** experimental results show that the proposed retrieval method is efficient and effective.

Dear Editor, In plants, the transport of sugars from the site of biosynthesis to the site of utilization or storage relies on sugar transporters located in different subcellular compartments and different vascular cell types. The SWEET sugar transporter family is one such class and is represented by 17 members in Arabidopsis. AtSWEET1 was the first plant SWEET transporter to be characterized; it acts as a glucose uniporter in multiple systems （Chen et al., 2010）.

ta and C ions extracted from a MEVVA ion source were implanted into Cr12 steel, with an implantation dose of (1-5)ｘ1017cm-2, extraction acceleration 42kV, and average ion beam flux about 20-50μA·cm-2. Rutherford backscattering spectrum (RBS) was used to measure the surface composition after ta and ta+C implantation. Analysis of phase formed by ta and C implantation was carried out by X-ray diffraction analysis (XRD). Experiment results showed that the wear rate of the implanted layer dropped 40% for ta ion implantation and by a factor of 2.7 for ta+C dual ion implantation. ta+C dual ion implantation was found to reduce the friction coefficient of Cr12 steel. The wear mechanisms of the implanted layer were discussed.

Ensuring complex pre-operative patient preparation before planned surgery is an essential preventive measure of SSIs （surgical site infections）. The aim of this study was to evaluate the difference in the effectiveness of the use of common soap and a tested product to reduce the occurrence of bacterial microorganisms on the skin surface in the area of the assumed surgical incision. Two hypotheses have been identified： h0： the tested product can be considered as beneficial for common pre-operative patient preparation in the incision area in order to significantly reduce the microbial load （decrease in CFU on a defined area of the blood agar by half of the original number and less）. h1： the tested product exceeds common soap by at least 20% when reducing the microbial load in the incision area. There were 80 microbiological prints examined on filter paper using the cultivation method on culture medium. The statistical method of the classic hypothesis test on the binomial distribution parameter versus the one-sided alternative has been used to process the results for the occurrence of microorganisms. The statistical processing of the results obtained by microbiological examination of prints allows for the confirmation of h0 and rejection of the h1 hypothesis. The results have shown the importance of proper pre-operative hygiene of the patient’s skin, regardless of the detergent base.

扶绥铝土矿是近年来在桂西南地区探获的一个典型喀斯特型铝土矿床。在野外地质工作的基础上,通过显微镜观察、X射线衍射、氢氧同位素测试等手段,对矿床中矿物组合及一水硬铝石、高岭石的氢氧同位素进行分析,探讨成矿环境的变化及硬水铝石的成因。结果表明:硬水铝石、高岭石是铝土矿石中的主要矿物,其次为勃姆石、赤铁矿、锐钛矿,沉积期矿石中还含有绿泥石和黄铁矿等,沉积期后矿石中含叶腊石、伊利石等,堆积矿石中均不含勃姆石。氢氧同位素测试表明:一水硬铝石的δ^(18)O值为0.95%~1.98%,δD值为-6.5%^-7.94%;高岭石δ^(18)O值为1.3%~1.89%,δD值为-7.04%^-8.97%。矿物组合指示,铝土矿沉积于缺氧环境中,沉积期后转变为富氧环境,且经历了干湿交替的气候变化。一水硬铝石氢氧同位素组成与钙红土三水铝石有较好的协调性,且兼具"风化壳"及"红土"的特征,反映其由钙红土风化壳演化而来。高岭石氢氧同位素组成推算沉积阶段温度为33℃,沉积期后为18℃,与二叠纪末期—中三叠世海水温度相似。扶绥沉积铝土矿的形成是对二叠—三叠纪全球气候变化的响应,且沉积阶段三水铝石或勃姆石向硬水铝石的转换与古特提洋俯冲作用有关的火山活动有密切关系;堆积铝土矿的形成则与印支运动及后来的表生喀斯特化作用密切相关。
