中国医药制造业企业政府创新补贴绩效研究

政府创新补贴逐渐成为企业研发资金的主要外部来源,但其对企业绩效的作用机制仍然模糊。根据医药制造业企业研发周期长、风险大的特点,在考虑时滞效应的基础上运用STATA12. 0构建静态回归模型,从微观角度分析政府创新补贴的创新绩效和财务绩效,以及在不同地区、不同企业性质和不同规模企业中的差异。研究表明:政府创新补贴会显著促进当期的研发投入,并且这一作用在东部地区、国企和小规模企业中表现更显著;政府创新补贴对未来一期的创新产出呈正U型关系,这种关系在东部地区、不同性质和不同规模企业中均显著;政府创新补贴对未来一期的财务绩效产生显著促进作用,这种促进作用在东部地区、小规模和非国有企业中表现更显著。研究结论对我国政府合理制定政府创新补贴政策和医药制造业提高创新能力提供了决策依据。     

Oogenesis in summer females of the rice water weevil, Lissorhoptrus oryzophilus Kuschel （Coleoptera： Curculionidae）, in southern Zhejiang, China

The rice water weevil, Lissorhoptrus oryzophilus Kuschel, has two generations in southern Zhejiang, China. To determine oogenesis in first-generation females （summer females） and its relations to temperature, females were collected from a rice field in early and mid-July and reared on young rice plants at 28, 31 and 34 ℃ in the laboratory. Percentage of females having oocytes, number of oocytes of different stages （stage-Ⅰ, from early previtellogenesis to middle vitellogenesis; stage-Ⅱ, late vitellogenesis; and matute-oocyte stage）, and length of ovarioles were determined every 10 d of feeding. At each temperature, oogenesis took place in over 40% of females after 20-40 d of feeding, but only 0.0-3.3 stage-Ⅰ, 0.0-0.8 stage-Ⅱ and 0.0-1.1 mature oocytes were observed at each observation date. Temperature had significant effect on number of stage-Ⅰ oocytes but not on number of stage-Ⅱ and mature oocytes in early July females; temperature had no significant effect on number of oocytes of either stage in mid-July females. Conclusively, in southern Zhejiang, summer L. oryzophilus females have great potential to become reproductive on rice, but their oogenesis activity is very low, with the overall procedures little affected by temperature.     

谈历法在历史教学中的作用

中国古籍浩若烟海。我们阅读、整理和研究这些古籍时,总要遇到有关时间的概念,即纪年、纪日等历法问题。古今历法不同,且古籍中纪年、纪日等常用天干、地支表示,或用别名代替,这就给后学者欲弄清某一历史现象的确切时间造成很大困难。必须将之换算成公历年、月、日,方可读懂古籍,加深对历史现象的认识,有利于学习与研究。所以,历法在历史及相关学科的教学中具有重要作用,掌握有关历法知识及干支公元换算等运用是学习与研究历史的一把钥匙。同时要破除迷信,树立科学的历史观。     

Calculation of the Phase Equilibrium of CO_2–Hydrocarbon Binary Mixtures by PR-BM EOS and PR EOS

The phase equilibrium data of CO_2 –hydrocarbon binary mixtures are important for the design and operation of CO_2 flooding, coal liquefaction, and supercritical extraction processes. Numerous pieces of binary phase equilibrium data have been obtained. Thus, models for the accurate calculation of binary and multicomponent mixtures must be developed on the basis of existing data. In this work, 3578 vapor–liquid phase equilibrium data points for 10 CO_2 –hydrocarbon binary mixtures, including CO_2 –butane, CO_2 –pentane, CO_2 –isopentane, CO_2 –hexane, CO_2 –benzene, CO_2 –heptane, CO_2 –octane, CO_2 –nonane, CO_2 –decane, and CO_2 –undecane, were collected. The PR and PR-BM equations of state(EOS) in combination with relevant mixing rules were used to calculate the phase equilibrium data of the CO_2 –hydrocarbon binary mixtures. The binary interaction parameter k ij in the PR EOS was temperature independent, whereas parameters in the PR-BM EOS were functions of temperature. Thus, the phase equilibrium data and other thermodynamic properties of the binary and multicomponent mixtures at different temperatures and pressures can be calculated by using the parameters obtained in this work. The PR-BM EOS performed better than the PR EOS, and the average absolute deviations over the temperature range of 255.98–408.15 K calculated by the PR EOS and PR-BM EOS were less than 5.74% and 3.36%, respectively. The results calculated by the two EOS were compared with those calculated by other models, such as PPR78, PR + LCVM + UNIFAC, KIE + PR EOS + HV, and PSRK. The phase equilibrium data of CO_2 –butane–decane, CO_2 –hexane–decane, and CO_2 –octane–decane ternary mixtures were calculated by the two EOS. The average overall deviations for the CO_2 mole fractions calculated by the two EOS were less than 7.66%.

Prenatal diagnosis of congenital fetal heart abnormalities and clinical analysis

INTRODUCTION Congenital heart disease (CHD) is the most common congenital disorder resulting in significant prenatal and postnatal morbidity and mortality (Gil- lum, 1994; Gembruch, 1997) and is believed to be a multifactorial disorder arising from the combined effect of genetic predisposition and environmental factors. Prenatal diagnosis of CHD is very important for both fetal prognosis and decreasing economic burden of family and society. It was demonstratedt t - l t recently that fe…

西方女权主义家庭心理治疗发展概况

随着系统论、信息论和控制论的发展 ,个体心理治疗被家庭整体治疗的方式所代替 ,家庭治疗是指以家庭为对象而施行的心理治疗方法 ,始于 1962年。 2 0世纪 70年代 ,随着女权主义的发展 ,女权主义者从性别角度入手 ,以对父权制的批判作为手段 ,以女性的眼光重新审视了传统的系统论的家庭治疗理论 ,在以上工作的基础上 ,女权主义者从各自的具体的领域提出了自己的家庭治疗观点。虽然女权主义者对传统家庭治疗的批判和重建的体系繁杂 ,尚未形成统一的理论和方法 ,但女权主义家庭治疗的观点已经成为了家庭治疗领域的新发展之一。
