The precipitates on austenite grain boundaries in an Nb-V-Ti microalloyed steel have been investigated by transmission electron microscope （TEM） examination of carbon extraction replica. The replica was prepared from specimen etched with saturated picric solution rather than Nital which is conventionally used. Then particles on both grain boundaries and triple point of grain [aoundaries were clearly observed and identified as （Nb,Ti）（C, N） parti- cles. In case of conventional way, it is difficult to determine the location of particles with respect to austenite grain boundaries. The number of particles observed in new way developed was greatly reduced compared with that found in replica prepared by the conventional way, which may be caused by the dissolution of partial precipitates during the etching with longer time and at higher temperature involved in new way. Despite this, the new way developed pro- vides an effective way to determine the precipitate particles on austenite urain boundaries_

In the presence of external forces depending only on the time and space variables, the Boltzmann-Enskog equation formally conserves only the mass of the . system, and its entropy functional is also nonincreasing. Corresponding to this type of equation, we first give some hypotheses of its bicharacteristic equations and then get some results about the stablity of its global solution with the help of two new Lyapunov functionals： one is to describe interactions between particles with different velocities and the other is to measure the L1 distance between two mild solutions. The former Lyapunov functional yields the time-asymptotic convergence of global classical solutions to the collision free motion while the latter is applied into the veri-fication of the L1 stability of global mild solutions to the Boltzmann-Enskog equation for a moderately or highly dense gas in the influence of external forces.

Objective: To evaluate the effect of comprehensive therapy based on Chinese medicine(CM) patterns on self-efficacy and satisfaction with its effectiveness in patients with chronic obstructive pulmonary disease(COPD). Methods: A total of 216 patients were randomly divided into the trial group(n=108) and the control group(n=108) based on the stratified and block randomization design. Patients in the trial group were treated with conventional Western medicine combined with Bufei Jianpi Granules(补肺健脾颗粒), Bufei Yishen Granules(补肺益肾颗粒), and Yiqi Zishen Granules(益气滋肾颗粒) according to the CM patterns respectively, and patients in the control group were treated with conventional Western medicine. The COPD Self-Efficacy Scale(CSES) and the Effectiveness Satisfaction Questionnaire for COPD(ESQ-COPD) were employed in a 6-month treatment and in further 6 month follow-up visit. Results: Among the 216 patients, 191 patients(97 in the trial group and 94 in the control group) fully completed the study. After 12-month treatment and follow-up, the mean scores of the trial group all continued to increase over time, which were significantly higher than those of the control group(Pmain: negative affect domain(12.13%), intense emotional arousal domain(12.21%), physical exertion domain(11.72%), weather/environmental domain(13.77%), behavioral risk domain(7.67%) and total score(10.65%). The trial group also exhibited significantly higher mean scores in the ESQ-COPD(Pmain: capacity for life and work domain(30.59%), clinical symptoms domain(53.52%), effect of therapy domain(35.95%), convenience of therapy domain(35.54%), and whole effect domain(52.47%). Conclusions: Bufei Jianpi Granules, Bufei Yishen Granules and Yiqi Zishen Granules can improve the self-efficacy and satisfaction of COPD patients.

In the era of the digital economy, great changes have taken place in the production and trading of enterprises. The emergence of digital technology has brought new impetus to optimize the layout of industrial structures and transform the old and new kinetic energy. Combined with the 14th Five-Year Plan and the requirements of domestic and international dual-cycle development, we construct an evaluation index system for the efficiency of industrial supply-side structural reform from the five dimensions of benefit improvement, innovation-driven, structural optimization, ECO development, and people’s liveli-hood benefit. Based on the data of Guizhou and Sichuan province from 2010 to 2019, the efficiency of industrial supply-side structural reform in Guizhou from the horizontal and vertical perspectives is evaluated by using the entropy weight TOPSISI model, and policy suggestions for industrial development in Guizhou are put forward. Results show that:(1) the level of industrial supply-side structural reform in Guizhou was on the rise since 2015, but the development rate had slowed in the past two years, and the gap was obvious with Sichuan;(2) there is a problem of insufficient development imbalance in Guizhou, which is lagging in four aspects, including benefit improvement, innovation-driven, ECO development, and people’s livelihood benefit.

Green development is the keynote of Yangtze River Economic Belt. It must insist on ecology preferential and green development which is not only respectation of natural laws but also the economic laws and social laws. The article uses SWOT analytic method to analyze the internal and external surroundings of the green development of Yangtze River Economic Belt on the basis of getting a clear understanding of its present developing status. Based on this the article puts forward the strategy pattern and path selection of green development of Yangtze River Economic Belt.

Wetlands provide many important services to human society, but are at the same time ecologically sensitive and adaptive systems, and are under heavy pressure. As a wetland city, Shanghai city has various types of natural wetlands (chiefly, includes coastal, riverine, lacustrine, and reservoir and pond wetlands), which account for 23.5% of total areas. Meanwhile, Shanghai is a metropolitan city, being confronted with the pressure of port expansion and urban and industrial sprawl, just like the other megalopolises in the world. Based on our earlier study on estimating the ecological service values of wetlands in Shanghai, this paper analyzed the ecological functions of the wetland city, such as nutrient cycling, water regulation and supply, food supply, disturbance control, water treatment, habitats and refugia, aesthetic, education and culture, tidal flats and potential land resources. Unfortunately, the wetland function was being degraded and the ecosystem service was discounted accordingly because of over-reclamation, over-fishing, water pollution, and rapid urbanization in the city. It’s therefore recommended that, to improve the environment of Shanghai ciry, and make the ecosystems sustainable function appropriately, the effective wetland management strategies should be taken.
