The reduction of hexavalent chromium [Cr(VI)] by microbiota agents is a potential method for ecological remediation in heavily contaminated soil. This study investigated the contribution microbial community and extracellular polymeric substances (EPS) to reduce Cr(VI) using lab-cultured anaerobic granular sludge (AGS). AGS demonstrated an impressive efficiency 99.3% soil, operating within initial concentration range 500-3000 mg/kg. distribution typical electron acceptors, e.g., SO42-, NO3-,...
When carrier phase observations are applied to high-precision positioning, how handle the cycle slip is an unavoidable problem. For correction, detection combination noise and ionospheric delay two crucial factors. Specifically, drastic changes in ionosphere increased of code will increase failure probability detection. To reduce influence observation bias, a novel method for BDS-3 satellites proposed. Considering that measurement closely related satellite elevation angle, elevation-based...
A new model is presented to resolve cycle slips detection for triple-frequency observations of BeiDou navigation satellite system (BDS) in this article when pseudorange are missing or insufficiently accurate under harsh special situations. Based on the first-order time-difference geometry-free (GF) pseudorange-phase combination model, and correction method based carrier phase Doppler proposed. With analyses two common sampling intervals (30 s 1 s), it can be concluded that optimal...
The problem of multi-path jamming is encountered when the radar tracking target, especially ship-borne TT & C target at sea. In this paper, characteristics marine interference are analyzed in detail, and diversity receiver technology phase-locked frequency discrimination deeply studied. Through test, studied paper has played a good anti-multipath performance use radar, improved accuracy data, important significance for accurate orbit determination.
