亚太经济 2016年第4期 66-71页

作者：文富德教育部人文社会科学重点研究基地四川大学南亚研究所

印度经济增长率超过中国的原因是多方面的,一是中印经济规模差距大;二是印度经济出现新的增长点;三是外国对印度投资大幅度增加。此外,对印度官方统计数据也存在疑问。

现有医学人类学对民族医疗的研究中,患者择医行为与民族文化的互动还是一个薄弱环节。事实上,患者面对躯体苦痛和医疗的风险与不确定性,在择医决策中会从地方性习俗中寻求文化策略支持。藏族患者的择医行为就受到传统文化的深刻影响。着眼藏族传统文化,特别是宗教民俗对患者择医的重要影响,可以加深对藏族医疗文化及地方实践的理解。从藏族医疗文化及相关积淀视角去关注群体内部差异,能对藏族患者的择医与传统文化间的关系有一个更为深入的了解。通过藏族患者择医文化因素及其个体间差异表现的深入分析,对揭示西部少数民族医疗文化与疾病治疗的互动、患者的疾病认知与行动逻辑以及对民族地区医患关系的认识和改善都有较高的参考价值。

To clarify association between armyworm（Mythimna separata） damage level and the corn growth and weed occurrence, we investigated corn plant height, stem diameter and vigor as well as weed coverage and biomass. The investigations were conducted at three locations of Shaanxi Province, China which were suffered seriously from armyworm. Significant correlations were found between the parameters analyzed. At stunted corn growth and presence of plenty of weeds, the armyworm damage tended to be heavy; oppositely, when corn grew well and weed density were low, armyworm harm was the minimal. Therefore, corn growing status and weed density can significantly affect armyworm damage level. Our results imply that promoting corn growth and timely removal of weeds are conducive to reducing armyworm occurrence.

Objective: To explore the influence of probucol-assisted retinal photocoagulation therapy on the visual performance and serum biochemical indexes in patients with early proliferative diabetic retinopathy. Methods: A total of 170 patients with early proliferative DR who were treated in the hospital between december 2014 and May 2017 were retrospectively analyzed and divided into the control group (n=107) who received retinal photocoagulation therapy alone and the probucol group (n=63) who received probucol-assisted retinal photocoagulation therapy. The differences in the contents of visual performance indexes as well as serum angiogenesis indexes, inflammatory mediators and oxidative stress indexes were compared between the two groups before treatment and after 6 weeks of treatment. Results: Before treatment, the differences in the levels of visual performance indexes as well as serum contents of angiogenesis indexes, inflammatory mediators and oxidative stress indexes were not statistically significant between the two groups of patients. After 6 weeks of treatment, mean vision, 30 visual acuity and 30-60 visual acuity of probucol group were higher than those of control group;serum angiogenesis indexes HIF-1, VEGF and Ang-2 contents were lower than those of control group;serum inflammatory mediators ICAM-1, IL-2, IL-23 and TNF-α contents were lower than those of control group;serum oxidative stress index MDA content was lower than that of control group whereas TAC content was higher than that of control group. Conclusion: Probucol-assisted retinal photocoagulation therapy can effectively optimize the visual performance and promote the homeostasis recovery in patients with early proliferative diabetic retinopathy.

The dual-stream function velocity field is reduced in order to analyze two-dimensional plate broadside roll- ing in roughing. The strain rate vector inner product and integral mean value theorem, as well as coqine vector inner product are used respectively in plastic deformation power, friction losses and shear power. A theoretical solution of roll torque and separating force for the rolling is obtained and the calculated results by the solution are compared with those measured in broadside rolling on-line. It shows that both the force and torque calculated are higher than those of measured, but the maximum relative error between them is no more than 11%.

活性聚合物由于其可形变的长链构象而表现出更丰富的动力学行为.本文通过郎之万动力学模拟研究了在周期性外场调制下活性聚合物的运动行为.我们发现柔性聚合物链有4种跨区域运动模式.外场的周期性区域宽度在活性聚合物行为的调控方面起到了关键作用.比如随着区域宽度的改变活性聚合物的扩散系数可以发生高达两个数量级的改变,其余如链的统计空间密度分布、整体受力情况、特征尺寸和取向等都表现出明显的非单调变化.这些变化反映了不同区域宽度下,聚合物链的构象特征及运动模式的改变.我们的研究为设计和调控活性聚合物的动力学行为提供了新思路,有望为可形变链状或长条状活性物质在生物、医学和材料领域的潜在应用提供参考.

This paper is concerned with a new numerical method of two dimensional flow. The governing system of differential equations is transformed into an equivalent system applied over a square grid network in order to overcome the difficulties and inaccurancies associated with the determination of characteristics near the flow boundaries. The MacCormack two step explicit scheme with second order accurancy is used for the solution of the transformed system of equations. Comparison between computed and experimental data shows a satisfactory agreement.

本文采用TVD格式求解二维可压非定常Euler方程组,对二维超声速混压式进气道进行了数值计算,首先模拟了后部压力对进气道的影响过程,当进气道的后部压力与入口压力的比值逐渐增加时,进气道内的正激波逐渐往前移动,当比值达到一个临界值,进气道将不起动。其次,通过对R52.1和R54.5两种进气道模型进行计算,对它们的总压恢复进行了对比。通过计算得到了喉道处曲线弧的曲率越大,进气道的总压损失越大,进气道也越难起动。
