为进一步推动虫害绿色防护技术发展，促进仓储工作高质量发展，针对浅圆仓采取下充上排式的二氧化碳气调工艺，通过考察试验仓内不同位置二氧化碳浓度变化情况、大豆品质指标变化情况和储粮害虫防治效果，研究二氧化碳气调技术对浅圆仓大豆储藏效果的影响，并与氮气气调技术进行了对比。结果表明：各检测点二氧化碳浓度维持35%以上的时间超过15 d；对锈赤扁谷盗、赤拟谷盗和玉米象等储粮害虫的防治效果显著，杀虫率达到100%；大豆粗脂肪酸值、蛋白质溶解比率和水分等指标变化较小；与氮气气调技术相比,二氧化碳气体损失的速度较氮气快，因此二氧化碳气调对仓房气密性要求更高，气调成本也更高,但二氧化碳气调技术所需密闭期较短,前期一次性投资较低。综上所述，在仓房具备良好气密性能的情况下，二氧化碳气调工艺杀虫效果显著。In order to further promote the development of green protection technology against pest and promote the high-quality development of warehousing, the carbon dioxide air conditioning process of filling low and discharging up was adopted for squat silo,and the impact of carbon dioxide air conditioning technology on the effect of the storage of soybean in squat silo by investigating the carbon dioxide concentration changes of the experimental silo in different locations, changes in soybean quality indexes and the effect of pest control in grain storage. In addition, the carbon dioxide air conditioning technology was compared with the nitrogen gas conditioning technology. The results showed that the concentration of carbon dioxide kept above 35% for more than 15 d at each detection point, and the control effect on pests such as Cryptolestes ferrugineus, Tribolium castaneum Herbst, and Sitophilus zeamais motschulsky was significant, and the killing rate reached 100%. The indexes of soybean fatty acid value, protein solubility ratio and water content changed little. The loss rate of carbon dioxide was faster than that of nitrogen, so carbon dioxide air conditioning had higher requirements for the air-tightness of warehouses, and its cost was also higher. However, carbon dioxide air conditioning technology required a shorter sealing period and a lower initial one-time investment. To sum up, under the condition that the warehouse has good air-tightness, the insecticidal effect of carbon dioxide air conditioning technology is remarkable.

The new technology of integrated prefabricated underwater push type final joint is adopted by the Shenzhen -Zhongshan Link. In order to ensure that the post welding process is in a dry environment, an "M -typed waterstop +inflatable waterstop" is installed between the push out section and the expansion section as a temporary waterstop measure during the construction period of the post welding section. M-typed waterstop is the first and most important waterstop measure. The final joint M -typed waterstop of the Shenzhen -Zhongshan Link is currently the world's largest size waterstop, with high quality requirements for installation of waterstops. Therefore, a special tooling process installation method has been developed to solve the problem of installing super large and ultra wide waterstops, ensuring installation quality. Through on -site practice of the final joint of the Shenzhen-Zhongshan Link, this process can be referenced and applied in similar projects. [ABSTRACT FROM AUTHOR]

Aiming at the problems of incomplete efficiency composition, limitation to single working condition calculation and lack of power loss analysis in the current efficiency model research of hydro-mechanical continuously variable transmission（HMT）, this study establishes a full-condition efficiency model of HMT considering the power loss of transmission components and accessories. Firstly, the general efficiency model of HMT variable pump-quantitative motor is established, and the relevant parameters are recognized according to the efficiency test data; then the efficiency models of other HMT transmission mechanisms and accessories are established, and the complete HMT efficiency model is obtained by combining the efficiency models of each part. Based on the self-developed HMT, the calculation is carried out to obtain the full working condition efficiency map and the loss power of each component mechanism, the test bench is built, and the efficiency test is carried out on the HMT to validate the accuracy of the model, and the average absolute errors of the efficiencies of the HM1 section and the HM2 section under full working condition are 0.027 3 and 0.026 1, respectively, which improve the accuracy of the HM1section and the HM2 section by 64.59% and 55.46% respectively, comparing to the accuracy of the comparative methods. Combined with the efficiency diagram and power loss situation to analyze the HMT efficiency characteristics and influencing factors, the results show that: 1) the HMT efficiency model in this paper is mainly affected by the load and the displacement ratio e of the hydraulic unit, and the influence of the input speed is not significant; 2) the main influencing factors of this paper’s HMT efficiency model are the load under the low load, and the displacement ratio under the high load; 3) the power loss of the pump motor has the greatest influence on the HMT efficiency, and the hydraulic loss power is large when e ＜ 0. The HMT efficiency is low; when e = 0, the hydraulic loss power is 0, and the HMT efficiency reaches the highest; 4) the power loss of gears and clutches does not have a negligible impact on the HMT efficiency, and the consideration of the power loss of other accessories is conducive to the improvement of the modeling accuracy. Measures to improve the efficiency of HMT:1) Try to avoid HMT working under power cycling conditions for a long time, and recommend operating at purely mechanical points and their nearby work points under the premise of prioritizing load demand and ensuring engine economy; 2) Avoid prolonged low load operation, and should be kept in high load conditions; 3) Select high-efficiency hydraulic unit or improve the transmission efficiency of the hydraulic unit by improving the parameters; 4) Improve parameters to reduce power loss under the premise of meeting the performance requirements of gears and clutches.

【Objective】The present paper aimed to study the effects of vermicompost co-applied with inorganic fertilizer on biological characteristics in rhizosphere soil of mulberry garden and mulberry leaf yield and quality for influences,to provide theoretical basis for fertilization in mulberry fields. 【Method】For the two consecutive years in a row in 2017-2018,four treatments were set up for the Nongsang 14 mulberry garden[T1 treatments for 100 % single application of fertilizer;T2 treatments for 100 % vermicompost;T3 treatments for 50 % vermicompost+50 % fertilizer;no fertilizer application as control(CK)],comparative analysis on the number of rhizosphere microbial communities,physical and chemical properties,mulberry leaf yield and leaf quality of each treatment were conducted.【Result】The number of bacteria,fungus and microorganisms in the rhizosphere soil of each fertilization treatment were significantly higher than those of CK(P<0.05,the same as below),but there was no significant difference between the number of actinomycetes in each treatment(P>0.05,the same as below). Among them,the number of bacteria(823.78×104 CFU/g),the total amount of microorganisms(1040.95×104 CFU/g) and the number of fungi(8.74×104 CFU/g) treated by T3 were the most,and the number of bacteria was significantly higher than that of T1(51.71 %),T2(14.41 %)treatment and CK(121.24 %), respectively. The total amount of microorganisms was significantly increased by 37.73 %,10.49 % and 77.49 %,respectively,compared with T1,T2 treatment and CK,but the difference in fungal number between T3 and T2 treatment was not significant. The pH of the rhizosphere soil of each fertilization treatment was significantly lower than that of CK,especially the lowest treatment with T3,while the contents of soil alkaline nitrogen,available phosphorus and available potassium were significantly higher than CK, T3 had the highest value,which was 47.05 %,62.58 % and 49.42 % higher than CK. The annual yield of mulberry leaves treated by fertilization was significantly higher than that of CK,especially the yield of T3 treatment(41 616.01 kg/hm~2),which was significantly higher than T1,T2 treatment and CK by 18.11 %,9.49 % and 41.24 %,respectively. The content of soluble sugar,crude protein and crude fat in each fertilization treatment was significantly higher than that in CK. Among them,T3 treatment had the highest soluble sugar content(13.64 %),crude protein content(24.49 %) and crude fat content(6.07 %). The soluble sugar content was significantly increased by 5.74 %,2.33 % and 24.23 %,respectively compared with T1,T2 treatment and CK. The crude protein content was significantly increased by 15.68 %,5.15 % and 26.89 %,respectively compared with T1,T2 treatment and CK,but the difference in crude fat content between T3 and T2 treatment was not significant. 【Conclusion】The combined application of 50 % vermicompost and 50 % fertilizer can significantly improve the rhizosphere environment of mulberry soil and greatly increase the yield and quality of mulberry leaves.

This study used suspended sediment concentration (SSC) data of a total of 23 stations to examine the spatial pattern of SSC in the Yangtze Estuary and Hangzhou Bay. These hourly data were collected during spring tides in both flood and dry seasons. Our results showed that there were significant spatial differences in this region. For example, the SSCs in the North Branch were much larger than that in the South Branch; the SSCs in the mouth bar area of the South Branch were larger than that in the upper reach; and the SSCs in Hangzhou Bay were larger than that in the Yangtze Estuary. It was also found that the SSCs increased first and then decreased longitudinally from the inner estuary to the open waters. Although these sediments mainly come from the Yangtze River, the SSCs in the Yangtze Estuary and Hangzhou Bay region are controlled by oceanic activity. The supplements from local bed sediments by re-suspension determine the spatial pattern of SSC in this region. Thus, the SSC levels in the Yangtze Estuary and Hangzhou Bay are primarily attributed to oceanic activity. [ABSTRACT FROM AUTHOR]
