Studying the characteristics and driving factors of chemical fertilizer pesticide application farmers is helpful for prevention control regional non-point source pollution (NPSP). In this study, 320 in Chongqing were surveyed, main influencing applications analyzed by spatial analysis partial least squares regression (PLSR). The results can be showed that: (1) Aaverage unit area N, P2O5 6.01 kg/ha/yr, 3.78 kg/ha/yr 107.89 g/ha/yr. Among them, rates large-scale households are 8.46 kg/ha/yr/,...
Due to limitations in the fabrication technology, large aperture space optical mirror is always spliced into several small segments rather than fabricated monolithically. To guarantee imaging quality of system, each segment needs be aligned at micron-level precision with millimeter-level range. For this purpose, a PZT actuated six-axis high-precision positioning which consists three serially connected parallel mechanisms proposed article. Compared previous 6-DOF solutions, such as Stewart...
This article presents the design, control, and test of a piezo-based passive compliant micro-gripper capable combining position force control. The gripper's structure is compact due to super-large amplification ratio 52 that achieved by two-stage displacement amplifier. position/force switching control strategy utilized for regulation. Particularly, dual feedforward controller Gaussian process regression based hysteresis compensator input shape technique vibration suppressor employed...
Fenton oxidation of <italic>p</italic>-nitrophenol was accelerated 3 times using a nano-pyrite catalyst. Homogeneous rather than surface catalysis dominated the ˙OH generation. Nano-pyrite supported fast Fe<sup>2+</sup> regeneration strengthens H<sub>2</sub>O<sub>2</sub> utilization.
Abstract Sclerotinia stem rot caused by sclerotiorum is one of the most important diseases oilseed rape in world. Because absence resistant varieties and disadvantages chemical control, application antifungal microbes has become an eco-friendly effective measure to control this disease. In study, Bacillus subtilis strain RSS-1, isolated from soil samples, was identified based on morphological, physiological biochemical tests, DNA gyrase subunit A ( gyrA ), gyrB , DNA-directed RNA polymerase...
Abstract This study focuses on the sources of organic carbon (OC) in surface sediments reservoirs mountainous regions, as well their dynamics and contribution mechanisms cycle. Spatial variations carbon, n‐alkanes, δ 13 C, 15 N were analyzed, a Bayesian isotope mixing model was applied to quantify relative contributions different OC sources. The results indicate that concentration range is 0.88%–3.72%. average long‐chain n‐alkanes 3.69 μg/g, accounting for 71.4%, indicating main source...
The bridge-type mechanism is one of the most widely used displacement amplifiers in micro-scale applications. However, a with an external load always works energy-inefficient situation due to storage strain energy flexural hinges, which can be validated by analytical model established this paper. In fact, majority cases, efficiency type only about 50%. To solve problem, highly efficient based on negative stiffness proposed paper, features compact size, simple design, symmetric structure, and...
Studying the temporal and spatial relationship between water body nutrients landscape elements in agricultural watershed will be helpful revealing process of non-point source pollution (NPSP). In order to quantitatively analyze effects on nitrogen phosphorus at multiple scales, Qi River basin located tail Three Gorges Reservoir was selected as study area, various methods such t-test, one-way analysis variance, pearson correlation redundancy were used. The results showed that (N) (P)...
Multivariate statistics are commonly used to identify the factors that control dynamics of runoff or sediment yields during hydrological processes. However, one issue with use conventional statistical methods address relationships between variables and yield is multicollinearity. The main objectives this study were apply a method for effectively identifying processes case study. combines clustering approach partial least squares regression (PLSR) models. was conducted in mountainous...
