Phanerochaete chrysosporium降解碳质金矿中元素碳高关联度变量的筛选

采用Plackett-Burman设计法对Phanerochaete chrysosporium降解碳质金矿中元素碳的高关联度变量进行筛选。通过前期的单因素试验确定影响真菌降解碳质物的8个变量,分别为愈创木酚浓度、糊精浓度、吐温-80浓度、草酸浓度、过氧化氢浓度、矿浆浓度、真菌浓度和作用时间。通过两水平的Plackett-Burman设计法确定影响真菌降解元素碳的高关联度变量,分别为愈创木酚浓度、草酸浓度和矿浆浓度。愈创木酚是一种诱导剂。低浓度时,愈创木酚通过提高酶活性和诱导一些酶产生,促进元素碳的降解。高浓度时,酶产生和酶活性受抑制,不利于元素碳的降解。草酸通过调节降解体系的p H值影响菌体生长及酶活性。矿浆浓度会影响元素碳和真菌的有效接触面积以及降解体系的剪切力和传质效率。

Investigation of Cross-Correlation Characteristics for Multi-Link Channels in High-Speed Railway Scenarios

This paper investigates the cross-correlation characteristics of large-scale parameters(LSPs) and small-scale fading(SSF) for high-speed railway(HSR) multilink propagation scenarios, based on realistic measurements conducted on Beijing to Tianjin HSR line in China. A long-term evolution-based channel sounding system is utilized in the measurements to obtain the channel data. By applying a proposed time-delay based dynamic partition method, multi-link channel impulse responses are extracted from the raw channel data. Then, the statistical results of LSPs, including shadow fading, K-factor, and root-mean-square delay spread are derived and the cross-correlation coefficients of these LPSs are calculated. Moreover, the SSF spatial correlation and cross-correlation of SSF are analyzed. These results can be used to exploit multi-link channel model and to optimize the next-generation HSR communication system.

ANALYSIS OF THE INFLUENCE OF TROPICAL CYCLONES AND ASSOCIATED SYNOPTIC SYSTEMS ON STRONG MEIYU IN SHANGHAI

With the methods of correlation and composite analyses, Ju et al. discussed the relationship between low-frequency oscillation in the summer monsoon region in East Asia and droughts/floods in the middle and lower reaches of the Yangtze River and found that strong monsoon years usually cause more rain in the region. Studying the interdecadal variation of precipitation in three rain zones over south China, the valley of Yangtze River and north China, Tan et al. showed that mid- and higher- latitude circulation and SST have important effect on the precipitation associated with summer monsoon in east China. With data of north Pacific SST and characteristic subtropical high, Cai et al.discovered that the anomalies of precipitation distribution in rainy seasons were directly affected by the activity of the subtropical high. As shown in an observational study, anti-correlation was found between the rainfall in the middle and lower reaches of the Yangtze River during the Mei-yu season and the frequency of TCs in northwest Pacific, including the South China Sea, in the prime of summer . The less active maritime TCs are, the more southward the westerly zone is over the Asian mid- latitudes. It is favorable for the Southwest Monsoon to transport moisture towards the region the Yangtze and Huaihe Rivers and for frontal rains to stagnate over the middle and lower reaches of the Yangtze, increasing the rainfall during Mei-yu. Otherwise, the mid-latitude westerly is located more northward, frontal rains develop north of the Yangtze River, the Mei-yu season shortens and rainfall decreases. Statistically studying the effect of South China Sea TCs and directionturning TCs on the Mei-yu season from 1980 to 1991, Kang et al.showed that 85% of the TCs had significant effect on Mei-yu and 35% of them would cause it to end. In addition, the Chinese meteorologists have long noted the cut-off role of TCs in the transportation of moisture by Southwest Monsoon to the Mei-yu fronts in the Yangtze and Huaihe Rivers. They found that TCs active offshore China would usually take moisture from the Bay of Bengal and cut off the transportation of moisture and transformation of energy for the frontal areas of Mei-yu, weakening, or even break and end the precipitation （like TC 9106, or Zeke）, but there were few TCs over offshore waters or even the west Pacific when Mei-yu was active. As shown in a numerical study, the disturbance of Zeke triggered a horizontal flow field at lower troposphere that weakened the Southwest Monsoon and further decreased its moisture transportation to the region of Yangtze and Huaihe Rivers and the convergence of moisture flux there. At the same time, the typhoon had indirect impact on the Mei-yu through its effect on the subtropical high.

Deformation mechanism of high-stress and broken-expansion surrounding rock and supporting optimization based on the gray correlation theory

Aiming at the large deformation and support problems of high-stress and broken-expansion surrounding rock, and taking 1 000 m level roadway of Mine II in Jinchuan as the research object, an investigation on the deformation and damage of roadway surrounding rock and an analysis of its mechanism were carried out. The gray correlation theory was used in support scheme optimization design. First, causes and mechanism of deformation of the 1 000 m horizontal transport channel were analyzed through field investigation, laboratory test and data processing methods. We arguued that poor engineering geological conditions and deep pressure increases were the main factors, and the deformation mechanism was mainly the ground deformation pressure. Second, the gray correlation theory was used to construct supporting optimization decision method in the deep roadway. This method more comprehensively considers various factors, including construction, costs, and supporting material functions. The combined support with pre-stressed anchor cables, shotcrete layer, bolt and metal net was put forward according to the actual roadway engineering characteristics. Finally, 4 support schemes were put forward for new roadways. The gray relational theory was applied to optimizing the supporting method, undertaking technical and economic comparison to obtain the correlation degree, and accordingly the schemes were evaluated. It was concluded as follows： the best was the flexible retaining scheme using the steel strand anchor; the second best was the one using plate anchors on the top and rigid common screw steel bolt on the two sides; the ttiird was; the rigid common screw steel bolt in full section of roadway; and the worst is the planished steel rigid support. The optimized scheme was applied to the 1000 m level of new excavation roadway. The results show that the roadway surrounding rock can reach a stable state after 5 to 6 months monitoring, with a convergence rate less than 1 mm/d.

Circulation anomalies associated with interannual variation of early- and late-summer precipitation in Northeast China

Summer rainfall is vital for crops in Northeast China. In this study, we investigated large-scale circulation anomalies related to monthly summer rainfall in Northeast China using European Center for Medium-Range Weather Forecast ERA-40 reanalysis data and monthly rainfall data from 79 stations in Northeast China. The results show that the interannual variation in rainfall over Northeast China is mainly dominated by a cold vortex in early summer (May-June) and by the East Asian summer monsoon in late summer (July-August). In early summer, corresponding to increased rainfall in Northeast China, an anomalous cyclonic anomaly tilted westward with height appears to the northwest and cold vortices occur frequently. In late summer, the rainfall anomaly is mainly controlled by a northward shift of the local East Asian jet stream in the upper troposphere and the northwest extension of the western Pacific subtropical high (WPSH) in the lower troposphere. The enhanced southwesterly anomaly in the west of the WPSH transports more moisture into Northeast China and results in more rainfall. In addition, compared with that in July, the rainfall in Northeast China in August is also influenced by a mid- and high-latitude blocking high over Northeast Asia.
