| 1 | Acoustic radiation field of the truncated parametric source generated by a piston radiator:model and experiment显示文摘A theoretical model is presented to describe the parametric acoustic field generated by a piston radiator. In the model, the high-frequency primary wave interaction region that is truncated by a low-pass acoustic filter can be viewed as a cylindrical source within the Rayleigh distance of the piston. When the radius of the piston is much smaller than the length of the parametric region, this model is reduced to the Berketey’s End-Fire Line Army model. Comparison between numerical calculations and experimental measurement show that the generated parametric sound field (especially near the axis) agrees well with the experiment results. | ZHAO Xiaoliang,ZHU Zhemin,DU Gonghuan (Institute of Acoustics and State Key Laboratory of Modern Acoustics, Nanjing University Nanjing 210093) TANG Haiqing,LI Shui,MIAO Rongxing (Hangzhou Applied Acoustics Institute Fuyang, Hangzhou 311400) | 2001 | Chinese Journal of Acoustics2001，20，1： | 8 |
| 2 | Effect of temperature on anoxic metabolism of nitrites to nitrous oxide by polyphosphate accumulating organisms显示文摘Temperature is an important physical factor, which strongly influences biomass and metabolic activity. In this study, the effects of temperature on the anoxic metabolism of nitrite(NO-2) to nitrous oxide(N2O) by polyphosphate accumulating organisms, and the process of the accumulation of N2O(during nitrite reduction), which acts as an electron acceptor, were investigated using 91% ± 4% Candidatus Accumulibacter phosphatis sludge. The results showed that N2O is accumulated when Accumulibacter first utilize nitrite instead of oxygen as the sole electron acceptor during the denitrifying phosphorus removal process. Properties such as nitrite reduction rate, phosphorus uptake rate, N2O reduction rate, and polyhydroxyalkanoate degradation rate were all influenced by temperature variation(over the range from 10 to 30°C reaching maximum values at 25°C). The reduction rate of N2O by N2O reductase was more sensitive to temperature when N2O was utilized as the sole electron acceptor instead of NO2, and the N2O reduction rates, ranging from 0.48 to 3.53 N2O-N/(hr·g VSS), increased to 1.45 to 8.60 mg N2O-N/(hr·g VSS). The kinetics processes for temperature variation of 10 to 30°C were(θ1 = 1.140–1.216 and θ2= 1.139–1.167). In the range of 10°C to 30°C, almost all of the anoxic stoichiometry was sensitive to temperature changes. In addition, a rise in N2O reduction activity leading to a decrease in N2O accumulation in long term operations at the optimal temperature(27°C calculated by the Arrhenius model). | Zhijia Miao Wei Zeng Shuying Wang Yongzhen Peng Guihua Cao Dongchen Weng Guisong Xue Qing Yang | 2014 | Journal of Environmental Sciences2014，26，2： | 7 |
| 3 | Examining the Relationship Between Spatial Configurations of Urban Impervious Surfaces and Land Surface Temperature显示文摘The urban heat island(UHI) effect has significant effects on the quality of life and public health. Numerous studies have addressed the relationship between UHI and the increase in urban impervious surface area(ISA), but few of them have considered the impact of the spatial configuration of ISA on UHI. Land surface temperature(LST) may be affected not only by urban land cover, but also by neighboring land cover. The aim of this research was to investigate the effects of the abundance and spatial association of ISAs on LST. Taking Harbin City, China as an example, the impact of ISA spatial association on LST measurements was examined. The abundance of ISAs and the LST measurements were derived from Landsat Thematic Mapper(TM) imagery of 2000 and 2010, and the spatial association patterns of ISAs were calculated using the local Moran’s I index. The impacts of ISA abundance and spatial association on LST were examined using correlation analysis. The results suggested that LST has significant positive associations with both ISA abundance and the Moran’s I index of ISAs, indicating that both the abundance and spatial clustering of ISAs contribute to elevated values of LST. It was also found that LST is positively associated with clustering of high-ISA-percentage areas(i.e.,>50%) and negatively associated with clustering of low-ISA-percentage areas(i.e.,<25%). The results suggest that, in addition to the abundance of ISAs,their spatial association has a significant effect on UHIs. | WU Xiangli LI Binxia LI Miao GUO Meixin ZANG Shuying ZHANG Shouzhi | 2019 | Chinese Geographical Science2019，29，4： | 3 |
| 4 | Method based on broadband compressed pulse superposition to measure properties of underwater acoustic materials显示文摘A method is proposed for the measurements of the performances of underwater acoustic finite sized large area material samples in a free field by using broadband pulse compression technique. As the result of which, the low-frequency cutoff of the standard tests is obviously reduced, and the broadband measurements are also realized. The experimental system provides measurements of complex reflection and transmission coefficients at continuous frequency points. From the data one can obtain the following acoustic parameters: echo reduction and insertion loss, absorption and attenuation coefficients, etc. The measurements are performed for two actual panels with the size 1 m x 1 m in the frequency range from 2-20 kHz. | LI Shui,MIAO Rongxing (National Defence Underwater Acoustic Metrology Center Fuyang Zhejiang 311400) | 2001 | Chinese Journal of Acoustics2001，20，1： | 2 |

| 8 | Plant metabolomics for studying the effect of two insecticides on comprehensive constituents of Lonicerae Japonicae Flos显示文摘Pesticides'overuse and misuse have been reported to induce ingredient variations in herbal medicine,which is now gaining attention in the medicinal field as a form of alternative medicine.To date,available studies on pesticide-induced ingredient variations of herbal medicine are limited only on a few compounds and remain most others unexamined.In this study,a plant metabolomics-based strategy was performed to systematically explore the effects of two frequently used insecticides on the comprehensive constituents of Lonicerae Japonicae Flos(LJF),the flower buds of Lonicera japonica Thunb..Field trials were designed on a cultivating plot of L.japonica with controls and treatments of imidacloprid(IMI)and compound flonicamid and acetamiprid(CFA).Unbiased metabolite profiling was conducted by ultra-high performance liquid chromatography/quadrupole-Orbitrap mass spectrometer.After data pretreatment by automatic extraction and screening,a data matrix of metabolite features was submitted for statistical analyses.Consequently,29 metabolic markers,including chlorogenic acids,iridoids and organic acid-glucosides were obtained and characterized.The relative quantitative assay was subsequently performed to monitor their variations across flowering developments.This is the first study that systematically explored the insecticide-induced metabolite variations of LJF while taking into account the inherent variability of flowering development.The results were beneficial for holistic quality assessment of LJF and significant for guiding scientific use of pesticides in the large-scale cultivation. | PAN Hui-Qin ZHOU Heng MIAO Shui GUO De-An ZHANG Xiao-Li HU Qing MAO Xiu-Hong JI Shen | 2021 | Chinese Journal of Natural Medicines2021，19，1： | 1 |
