Analyzing the thermal distribution on plane conditions objectively is difficult due to lack of enough meteorological observation stations within urban residential areas. In this paper satellite observations synchronous or quasi-synchronous with ground observations are adopted, and a teleconnection model is built between the satellite spectral and surface temperature for quantitative retrieval of temperature. Furthermore, by combining the satellite data with other multiple factors, a GIS comprehensive analysis model and a functional evaluation method for urban residential districts are established, which are used to study the relation between the air temperature and media characteristics on ground as well as the greening cooling effect in recent years in Shanghai. The results show that the air temperature in greened urban residential districts is generally lower than the average temperature and much less than the highest one. In general,the average air temperature in the greened area is at most 1.19℃ lower than the maximum temperature in the districts,which is 0.67℃ and 0.55℃ lower than that of the highest for buildings and roads respectively. The temperature is inversely proportional with greening fraction but is directly proportional with the ratio of roads and buildings. The higher the greening fraction in internal residential districts, the lower the temperature, and the higher the ratio of road and building is, the higher the temperature. 展开更多

In this experiment lung carcinoma was induced by crocidolite plus benzo(a)pyrene in rat. From the cancer models, we observcd that the incidcnce (16.0%) of lung carcinomas was lowel, and the survival time (376 days) of the first case of carcinoma and the mean survival time (758 days) of the rats with carcinoma were higher in the group of rats drinking 2% green tea extract for life than in the positive group (without drinking green tea extract). The mortality ratio (0.5047) was smaller in the cxperimental group than in the positive control group, and the survival curve of the experimental group significantly raised up, in comparison with the positive group. 展开更多

Objective: To observe the therapeutic effect of Qinglong Bai Wei Zhen Fa (Green Dragon Shaking Tail Needling) in the treatment of scapulohumeral periarthritis. Methods: A total of 231 cases of scapulohumeral periarthritis patients were randomized into treatment group (n=123) and control group (n=108). In treatment and control groups, Jianyu (LI 15), Jianqian and Jianhou were used as the main acupoints and stimulated with Green Dragon Shaking Tail Needling and conventional needling separately. Additionally, in control group, Waiguan (TE 5) and Binao (LI 14) were supplemented. The treatment was given once daily, with 10 days being a therapeutic course, 2 courses altogether. Results: After the first course of treatment, in treatment and control groups, the cured, the markedly improved, the effective and ineffective cases were 49 and 12, 61 and 33, 11 and 40, 2 and 23, with the total effective rates being 98.4% and 78.7% respectively. There was a marked difference between two groups in the therapeutic effect (P<0.05). Following 2 courses of treatment, the cured, the markedly improved, the effective and ineffective cases were 66 and 21, 47 and 41, 10 and 39, 0 and 7, with the total effective rates being 100% and 93.5% separately. No significant difference between two groups in the total effective rates, but the cure rate of treatment group was strikingly higher than that of control group. Conclusion: Green Dragon Shaking Tail Needling is significantly superior to that of conventional needling in the treatment of scapulohumeral periarthritis. 展开更多

In the context of global carbon neutrality,new energy vehicle promotion(NEVP)has become an important means of reducing carbon emissions.This paper constructs a theoretical model and uses panel data on NEVP in 21 countries from 2012 to 2018 to empirically examine the green effect of NEVP.The results indicate the following:(1)NEVP significantly reduces greenhouse gases emissions,and the green effect can be transmitted and diffused through a direct path.(2)Replacing fuel-fired vehicles and accelerating the end-of-life vehicle scrapping process significantly conducted the green effect,and aggravating traffic congestion was not statistically significant.(3)The transmission mechanism of the green effect is regulated by regional economic heterogeneity.In regions with better development of fuel-fired vehicles,the transmission of the green effect is subject to the elimination of fuel-fired vehicles and traffic congestion governance,and the transmission efficiency is low.However,regions with a relatively weak fuel-fired automobile industry foundation show a strong“advantage of backwardness”,and the green effect is more prominent.This means that global NEVP should be further accelerated to achieve the green effect and the goal of global carbon neutrality. 展开更多

In GaN-based green light-emitting diodes(LEDs) with different green quantum well numbers grown on Si(111)substrates by metal organic chemical vapor deposition are investigated. It is observed that V-shaped pits appear in the AFM images with the green quantum well number increasing from 5 to 9, and results in larger reverse-bias leakage current. Meanwhile, in the case of the sample with the number from 5 to 7 then to 9, the external quantum efficiency increases firstly, and then decreases. These phenomena may be related to the size of V-shaped pits in the active area and the distribution of electrons and holes in the active area caused by V-shaped pits. The optimal number of green quantum wells is determined to be 7. 展开更多

The present study aimed at clarifying whether Chinese green tea, coffee and levamisole (LMS) have similar Inhibitory effect on hepatocarclnogenesis induced by diethylnltrosamine (DEN) as they had been proved in our previous aflatoxin B1 (AFB1) experiments. Male Wistar rates were divided into control (A), green tea (B), coffee (C) and levamisole (D) groups. All rats received the same basic DEN treatment according to the program originally designed by Solt and Farber. During the two weeks before and one week after i. p. injection of DEN, the group B, C and D were given 2. 5% green tea, 5% coffee and 0. 1% LMS diet, respectively. The results demonstrated that coffee, LMS and , in particular,green tea showed Inhibitory effect against DEN-induced hepatocarcinogenesis, indicating that green tea can be used as chemopreventive agent for DEN-, as well as for AFB1-induced hepatocarcinogenesis. 展开更多

[Objective]The paper was to study the control effect of pheromone insect-attracting board on tea green leafhopper(Empoasca vitis Gothe)in fields. [Method]Pheromone insect-attracting board and ordinary insect-attracting board were used to trap tea green leafhopper in fields,and control efficacies were studied.[Result]The daily trapping effect of pheromone insect-attracting board on tea green leafhopper was 19.0 insect/grid,while that of ordinary insect-attracting board was 13.8 insect/grid.The highest control effect of pheromone insect-attracting board and ordinary insect-attracting board were 71.6% and 63. 6%,respectively.The distribution of tea green leafhopper in two types of boards showed the following regularities:more in upper edge and less in lower edge of boards,more on both sides and less in the middle of boards.The mean values of control effects of two insect-attracting boards were significantly different(t =5.66 展开更多
