司法警官职业院校属于行业办学高职院校,其警察类专业之间共性要素多,专业基础相通,职业面向均为人民警察,教学资源高度共享,适合组群建设。目前,全国16所司法警官职业院校中有10所入选省级以上“双高计划”建设项目。其中,警察类专业群在省级高水平专业群中占主导地位,但存在专业群组织形式以“跨院系整合”为主、专业群课程体系不健全、服务行业水平不高等问题。加强高水平专业群建设的路径有:健全专业群组织管理机制;深化产教融合;推进科教融汇;加强专业群课程体系建设;构建专业群师资队伍建设机制。

High performance Ag-Pb-Sb-Te system thermoelectric bulk materials were fabricated by a combination of mechanical alloying (MA) and spark plasma sintering (SPS). Phase composition and microstructure of the resultant materials were investigated by X-ray diffraction (XRD) and scanning electron micros-copy (SEM) analysis. A special emphasis was paid to the effects of chemical composition, especially the Pb content on the thermoelectric properties of the Ag0.8Pb18+xSbTe20 samples, including electrical resistivity, Seebeck coefficient, power factor, thermal conductivity and dimensionless figure of merit. The present study reveals that the optimal composition of Ag0.8Pb18+xSbTe20 samples is Ag0.8Pb22.5SbTe20 and the maximum figure of merit (ZT) is 1.2 at 673 K.

Aim： To investigate the role of a novel dipeptidyl peptidase 8 transcript variant （DPP8-v3） gene in testis development and/or spermatogenesis. Methods： A human testis cDNA microarray was hybridized with mRNA of human adult and fetal testes. Differentially expressed clones were sequenced and characterized and their expression was analyzed by real-time reverse transcription polymerase chain reaction （RT-PCR） and Southern-blot analysis. Results： A new transcript variant of the human dipeptidyl peptidase （DPP8）, exhibiting a 5-fold higher expression level in human adult than that in fetal testes, was cloned and was named DPP8 variant 3 （DPP8-v3）. The full-length sequence of DPP8-v3 was 3,030 bp, encoding a protein of 898 amino acids. Conclusion： DPPS-v3 is a novel human DPP8 transcript variant highly expressed in the adult testis. Similar to DPPIV, DPP8-v3 may play a key role in the immunoregulation of testes and accordingly may influence spermatogenesis and male fertility. （Asian J Androl 2005 Sep; 7： 245-255）

川西冕宁-德昌稀土成矿带是我国重要的稀土成矿带之一,然而壳源混染与稀土成矿之间的关系尚缺乏有效制约。辉钼矿Re-Os同位素体系已发展成为示踪壳源混染作用的灵敏指示剂。为了揭示壳源混染在川西碳酸岩型稀土成矿中的作用,对牦牛坪和木落寨稀土矿床开展了辉钼矿Re-Os同位素研究。岩相学特征表明,辉钼矿在岩浆期产出于方解石间隙中,在伟晶岩期产出于石英间隙中,在热液期与热液矿物、硫化物共生。牦牛坪稀土矿床2件辉钼矿样品Re-Os模式年龄分别为25.93和26.05 Ma,Re含量(质量分数,下同)分别为44.933×10^(-6)和28.678×10^(-6);木落寨稀土矿床的辉钼矿样品Re-Os模式年龄为28.90 Ma,Re含量为38.765×10^(-6)。辉钼矿形成年龄与稀土矿床成岩成矿年龄一致,说明辉钼矿沉淀与稀土成矿同期,3件辉钼矿样品Re含量均为10-5数量级,表示其成矿物质具有壳幔混合特征。壳源混染中和了稀土成矿流体pH值,使稀土-氯化物和稀土-硫酸盐失稳,富CO 2含钼流体的混合促进了成矿流体中CO^(2-)_(3)与稀土元素结合,导致氟碳铈矿的沉淀。

The use of peat for the removal of nickel from aqueous solutions has been investigated at various pH values by means of static conditions. The present research shows that the ability of Ni to bind to peat increases as the pH value increases. The solutions reach adsorption equilibrium rapidly. A reasonable kinetic model, first-order in nickel concentration, has been developed and fitted to the adsorption of nickel （Ⅱ） onto peat. The first-order model provides a good correlation to the experimental data. The characteristic parameters of the Langmuir isotherm were determined at various temperatures. The relationship between kinetics and equilibrium isotherms was established through the forward- and backward-rate-constants, k~ and k2, and the equilibrium constant, K.
