不同消费群体对经济增长的作用及收入政策分析

根据我国个人消费者的不同消费水平，可将其划分为四种不同类型的个人消费群体，即百元级消费群体主要是农民消费群体（I类），千元级消费群体主要是工人消费群体（Ⅱ类），万元级消费群体主要是公职人员消费群体（Ⅲ类），十万元级消费群体主工是个体经营者和私人企业主消费群体（Ⅳ类），在四种消费群体中，对经济增长起决定作用的是Ⅱ类和Ⅲ类消费群体，他们数量较大而且消费水平适中，I类消费群体虽然数量很大，但是消费水平较低，对经济增长的短期效果不明显；Ⅳ类消费群体消费水平较高，但人数较少，对经济增长可起到一定的示范作用。因此，对四类不同消费群体的个人收分配政策是：减轻农民负担，增加农民收入；扩大工人就业，完善社会保险制度；有限度地提高公职人员收入，促进其消费水平提高；调节个人经营者和私人企业主的个人收入，引导其合理消费。

关于有效刺激消费拉动经济增长的思考

长期以来,山西经济主要是靠投资、消费和进出口“三驾马车“拉动。目前金融危机全球蔓延并波及我国的情况下,短期内政府扩大投资是拉动经济增长最直接的办法,增强消费者对经济前景的信心、对政府执政能力以及经济政策实施贯彻效率的信心,是有效刺激消费、扩大内需、拉动经济增长的根本做法,调结构、促转型,保持经济平稳较快发展是长远之策。     

黑龙江省矿业产业结构对经济增长效益分析

区位商是用来分析区域产业结构中专业化部门及其专业化程度的指标。区域某一产业的区位商如果大于1，表明研究区域在某产业部门的集中程度大于较高层次区域平均水平，该产业部门的产品可以“外输”，区位商值越大，则研究区域在该产业部门的集中程度越高；如果区位商小于1，则该产业部门不是研究区域的专业化部门，且产业部门的产品需要“内进”；如果区位商等于1，则表明该产业部门产品供需平衡。

The effect of toxic sulfide exposure on oxygen consumption and oxidation products in Urechis unicinctus (Echiura: Urechidae)

To investigate sulfide detoxification in Urechis unicinctus,oxygen consumption rate and sulfide detoxification productswere analyzed during sulfide exposure under controlled laboratory conditions.The results showed that oxygen consumption rateswere elevated significantly during 3 h sulfide exposure compared to the control(P0.05).The concentration of sulfite in body walland hindgut of experimental worms increased significantly(P0.05)when exposed to 50μmolL-1sulfide,reached a maximum at24 h and then decreased.Similar result was observed in worms exposed to 150μmolL-1sulfide except that sulfite concentrationreached a maximum at 12 h.Contents of thiosulfate in body wall and hindgut of U.unicinctus exposed to sulfide were also significantly higher than that of the control without sulfide exposure.In conclusion,during short-time sulfide exposure U.unicinctus mayraise oxygen consumption to detoxify toxic sulfide into sulfite and thiosulfate.Sulfide detoxification was restrained when the expo-sure time was prolonged or sulfide concentration was increased,which was indicated by decrease of sulfite,the intermediate productof sulfide detoxification.     

多级次地下水流系统的最小能耗率原理初探

20世纪60年代初期,Tóth基于定水头上边界条件推导出解析解,得出多级次地下水流系统,是水文地质学里程碑式的突破,成功地解决了一系列理论和实际问题。但Tóth解析解存在的缺陷也长期沿袭：单纯重视数学模拟而忽视物理机制;将地形控制地下水位看成是普适性规律;忽视给定水头上边界数学模拟的失真。这些缺陷,尤其是忽视物理机制探究,不仅妨碍Tóth理论自身发展,而且导致地下水流系统理论尚未被国际水文地质界普遍接受。参照河流动力学中应用的最小能耗率原理,类比提出地下水流最小能耗率的表达式。基于已有的通量上边界地下水流模式数值模拟结果,进一步探究物理机制,归纳得出地下水流系统遵循最小能耗率原理的结论。     

取样电阻对功耗分析攻击的影响

针对目前针功耗分析攻击的影响因素研究偏少的情况,讨论和分析了取样电阻对功耗分析攻击的影响.功耗分析攻击的研究对象是功耗曲线,现有常见实验平台采集的通常是包括各种噪声的功耗综合.取样电阻作为功耗分析平台中的一部分,会在电阻噪声和功耗区分度两方面造成影响,进而影响到功耗分析攻击的正确率.因此为了提高攻击正确率,在不影响区分度的前提下可选用相对小的电阻.

The effects of recombinant eel growth hormone,methyltestosterone and L-thyroxine on the growth of red sea bream,Pagrosomus major

the effects of recombinant eel growth hormone (reGH), methyltestosterone (MT) and L-thyroxine (T4) on the growth of red sea bream,Pagrosomus major, were investigated. Administration of reGH to fry by immersion at 2 mg/1 for 2 h every 5 days resulted in significant increase in both weight and length, but the condition factor (CF) diminished relative to that of similarly treated controls over the 37 day treatment period. Immersion in 0.1 mg/l T4 also resulted in significant increase in both weight and length and higher survival rate of test fry compared to the controls. Immersion in MT had less effect on growth and high-dose resulted in high mortality. In the second study, injection of 2 μg reGH/(g·wk) caused a significant increase in the specific growth rate (SGR) of test red sea bream fingerlings relative to that of the controls during the 4—week treatment period and maintained the increasing trend over the post-treatment period (weeks 4–6). Injection of MT at a dosage of 1μg/(g·wk) resulted in a significant increase in SGR during the 4—week treatment period. Intramuscular injection of 0.1 μg T4/(g·wk) also resulted in a significant increase in weight. Injection of high-doses of MT and T4 inhibited growth and resulted in darkening skin, bulging eyes and thinning body. In muscle chemical composition, the treated groups had no significant differences compared to the controls, but the high-dose MT and T4 groups showed significant increases in lipid content. Potential practical methods for hormone application in fish culture are discussed.     

The Effect of Temperature on Growth and Energy Budget of the Polychaete,Neanthesjaponica Izuka

Growth and energy budget of the polychaete, Neanthesjaponica, at various temperatures （17, 20, 23, 26 and 29℃） were investigated in this study. The growth, as indicated by final dry weight and specific growth rate （SGR）, increased with increasing temperature, with the maximum level at 26℃, and then decreased significantly at 29℃. A similar trend was observed in feeding rate, food conversion efficiency （FCE） and apparent digestive rate （ADR）. However, no significant differences were detected in ADR among all the temperature treatments. In the pattern of energy allocation, faeces energy was only a small component of energy budget and had little influence on the proportion of food energy allocated to growth. The metabolic energy accounted for a large portion of energy intake for each temperature treatment. The nitrogen excretion was appreciable with changing temperature. The two expenditure terms （respiration energy and excretion energy） in energy budget were the major factors influencing the proportion of food energy allocated to growth. These results revealed that temperature affected the growth of N. japonica mainly by influencing feeding rate and FCE. In addition, regression equations describing the relationship between feeding rate, faecal production, SGR, FCE and temperature were obtained. The optimum temperatures for feeding rate, FCE and SGR were estimated at 25.01 ℃, 24.24℃ and 24.73 ℃, respectively, from the regression equations.
