父母教养方式与儿童依赖性的关系探析

为探求父母教养方式和儿童依赖性的关系以及何种教养方式下儿童的依赖性水平相对较低,特进行了此次研究。此次研究以380名学生为研究对象,运用父母教养方式评价量表（EMBU）和依赖性量表对父母教养方式和儿童依赖性进行了系统的测量,运用SPSS软件对数据结果进行处理分析。研究发现,父母教养方式与儿童依赖性存在一定的相关。     

Impact of individual acid flue gas components on mercury capture by heat-treated activated carbon

Elemental mercury capture on heat-treated activated carbon (TAC) was studied using a laboratory-scale fixed bed reactor. The capability of TAC to perform Hg⁰ capture under both N₂ and baseline gas atmospheres was studied and the effects of common acid gas constituents were evaluated individually to avoid complications resulting from the coexistence of multiple components. The results suggest that surface functional groups (SFGs) on activated carbon (AC) are vital to Hg⁰ capture in the absence of acid gases. Meanwhile, the presence of acid gas components coupled with defective graphitic lattices on TAC plays an important role in effective Hg⁰ capture. The presence of HCl, NO₂, and NO individually in basic gases markedly enhances Hg⁰ capture on TAC due to the heterogeneous oxidation of Hg⁰ on acidic sites created on the carbon surface and catalysis by the defective graphitic lattices on TAC. Similarly, the presence of SO₂ improves Hg⁰ capture by about 20%. This improvement likely results from the deposition of sulfur groups on the AC surface and oxidation of the elemental mercury by SO₂ due to catalysis on the carbon surface. Furthermore, O₂ exhibits a synergistic effect on Hg⁰ oxidation and capture when acid gases are present in the flue gases.     

Optimal design of the separate type heat pipe heat exchanger

Separate type heat pipe heat exchangers are often used for large-scale heat exchanging. The arrangement of such a heat exchanger conveniently allows heat input to and output from the heat exchanger at remote locations. The traditional method of designing an ordinary HPHE （heat pipe heat exchanger） is commonly applied in the separate type exchanger design, but the calculations have to be carried out separately, which makes it very complicated. In this work, the ε-NTU （effectiveness-Number of Transfer Units） method was applied for optimization analysis of single- or multi-level separate type heat pipe heat exchangers. An optimizing formula for single-level separate type heat pipe heat exchangers was obtained. The optimizing principles of effectiveness-NTU and heat transfer rate by the equal distribution method for multi-level separate type heat pipe heat exchanger are presented. The design of separate type heat pipe heat exchangers by the optimizing method is more convenient and faster than by the traditional method.     

来自煤炭行业的呼声

煤炭是我国重要的基础能源和原料,在国民经济发展中具有重要的战略地位.据预测,2005年全国煤炭需求总量为20亿吨,2010年为24亿吨左右,在我国一次能源消费结构中,煤炭的比重一直占到70%左右,在今后相当长的时期内,我国以煤炭为主的一次能源结构不会发生根本性变化.

Scale-up of rifamycin B fermentation with Amycolatoposis mediterranei

Study of the effect of dissolved oxygen and shear stress on rifamycin B fermentation with A. mediterranei XC 9–25 showed that rifamycin B fermentation with Amycolatoposis mediterranei XC 9–25 needs high dissolved oxygen and is not very sensitive to shearing stress. The scale-up of rifamycin B fermentation with A. mediterranei XC 9–25 from a shaking flask to a 15 L fermentor was realized by controlling the dissolved oxygen to above 25% of saturation in the fermentation process, and the potency of rifamycin B fermentation in the 15 L fermentor reached 10 g/L after 6-day batch fermentation. By continuously feeding glucose and ammonia in the fermentation process, the potency of rifamycin B fermentation in the 15 L fermentor reached 18.67 g/L, which was 86.65% higher than that of batch fermentation. Based on the scale-up principle of constantly aerated agitation power per unit volume, the scale-up of rifamycin B fed-batch fermentation with continuous feed from a 15 L fermentor to a 7 m³ fermentor and further to a 60 m³ fermentor was realized successfully. The potency of rifamycin B fermentation in the 7 m³ fermentor and in the 60 m³ fermentor reached 17.25 g/L and 19.11 g/L, respectively.
