The results showed that the coverage of paspalum wetsfeteini and Dolichos lablab were 100% and 93%, which increased by 3.70 and 3.44 times compared with Lolium perenne, respectively; their relative crowding coefficient with E. adenophorum were 7.09 and 22.78, which increased by 2.43 and 7.80 times compared with L perenroe, respectively. Using excavation method, the control efficacies of replacement plants were 99.3 % and 96.9%, respectively, while the control efficacy of replacement plants using mowing method was lower than 66.4%. The overwintering rate of P. wetsfeteini in the following year was 95% ; its coverage was still 100% and its control efficacy against E. adenophorum remained over 99%. D. lablab was difficult to survive the winter in the north region beyond 26.2°N, so it could only be applied as annual replacement plant. The coverage of Setaria anceps, Cajanus cajan and other test plants were less than 90%, with poor control efficacy against E. adenophorum.展开更多

[ Method] Five high quality forages including Lolium perenne, Dactylis glomerata, Setaria anceps, Trifolium repens and Medicago sativa were planted in the fields invaded by E. adenophorum, and their ecological adaptability and control effect against E. adenophorum were studied. [Result] Five kinds of forages could nor- mally grow at the local land. The indexes such as coverage, plant height, fresh weight of stems and leaves of S. anceps were the highest, and it showed very strong ecological adaptability as well as the best control effect on E. adenophorum, up to 97.85% and 93.81% at the first and second year, respectively, indicating good sustainable control effect. D. glomerata ranked the second place, of which the coverage after one year was 86% and the control effect on E. adenophorum was 89.68%. The other species showed poor control effect on E. adenophorum because of slow growth rate and heavily damage from companion weeds even they could establish dominant communities. [ Condusion] The paper provided reference for ecological control against E. adenophorum in local land and ecological restoration of invasive land.展开更多

Methods: the data of 80 patients with mixed hemorrhoids collected from May 2019 to March 2021 in Suzhou Xiangcheng District Hospital of Traditional Chinese Medicine were collected and sorted out. The patients who had incomplete data, were participating in other researchers and did not meet the standard were divided into two groups according to the order of admission (control group and observation group, 40 patients in each group). The control group used fluid replacement control methods, including control of fluid replacement volume (intravenous fluid infusion volume and oral intake) and adjustment of infusion speed 2 h after operation. The observation group used the method of auricular point pressing beans and fluid infusion control, and compared the urination of the two groups after operation. Results: in the observation group, the scores of voiding smoothness (1.90±0.32, 1.40±0.29) at 4 h and 5-6 h after operation were lower than those of the control group (2.45±0.41, 1.88±0.31), the time of first urination (2.02±0.98) h was shorter than that of the control group (3.04±1.11) h, the volume of voiding (480.00±20.56)mL was higher than that of the control group (400.00±33.00)mL at 2 h after operation, and the incidence rate of urinary retention (2.5%) was lower than that of the control group (20.0%) Conclusion: auricular acupressure combined with controlled fluid infusion has significant effect in preventing urinary retention after mixed hemorrhoid operation.展开更多

At first,lag synchronization scheme for identical master-slave Lur‘ e systems by replacing variables control and the relevant error system are given, and the relations between absolute stability of the error system and the chaotic lag synchronization are described. Then, based on a quadratic Lyapunov function, two new Lur‘ e criteria for the above chaotic lag synchronization are proved. Four corresponding frequency domain criteria are further derived by means of Meyer-Kalman-Yacubovia Lemma. These frequency domain criteria are applied to analyze the lag synchronization of general master-slave Chua's circuits so that some ranges of the parameters in which the master-slave Chua's circuits achieve chaotic lag synchronization by replacing single-variable control are attained. Finally, some examples are given to verify the theoretical results.展开更多
