This paper analyzed the content, distribution, and sedimentation mechanism of Cd in Jiaozhou Bay based on investigation data in April, July and October 1985. Results showed that the Cd contents in surface waters ranged from 0.04-0.32 g L-1, and were meeting Grade I for Cd (1.00 g L-1) in Chinese Sea...

We analyzed the horizontal distribution, vertical distribution and sedimentation process of Cd in Jiaozhou Bay based on investigation data in April, July and October 1985. Results showed that Cd contents were in order of summer > autumn > spring. For spacial scale, the seasonal variations of Cd in surface...

Based on investigation data on petroleum hydro-carbon (PHC) in April, July and October 1985 in Jiaozhou Bay, we analyzed the content, pollution level and diffusion of PHC. Results showed that PHC contents were ranging from 0.010-0.124 mg L-1, indicating that this bay had been moderate polluted by PHC,...

Change detection is an ongoing hot topic in multi-spectral imagery applications, how to exploit the available spectral information effectively for change detection is still an open question. Considering the noise interference and redundancy of multi-spectral imagery, it is important and necessary to...

Role car ESP hydraulic system is applied to the appropriate wheel hydraulic braking force, the implementation of active intervention of the vehicle, so that the car during braking, good stability, and therefore directly affect the effective control of the ESP braking car security. Thesis for the dynamic...

To determine optimum extraction process of volatile oil from flower of Scindepus aureus and analyze its chemical composition. The essential oils were extracted from S. aureus by microwave-assisted extraction (MAE), distillation time, solid-liquid ratio. Microwave Power were investigated with extraction...

Objective: The literature remains controversial on ras gene mutation prognostic significance for survival in AML and MDS. In this paper, study meta-analysis of its occurrence and prognostic relevance in acute myeloid leukemia and Myelodysplastic syndromes. Methods: The PubMed, Cochrane Library, EBSCO,...

Large particle size limestone (CaCO3) is an important raw material used in many branches of industry. For lacking of reaction parameters of large particle size limestone, numerical analysis method is used to study the decomposition reaction kinetics of limestone to understand the thermal decomposition...

In standard runoff plots with 10° and 15° slope croplands in purple soil areas, the paper studies influences of plant hedge on slope water and soil loss for slope croplands in purple soil areas under the natural rainfall conditions comprehensively and analyzes control actions of plant hedge’s intervals...

Magnesium ammonium phosphate by adding magnesium salt and phosphate to ammonia nitrogen landfill leachate,The medicament and ammonia nitrogen landfill leachate Mg2+ PO3- ions in NH4+ after chemical reaction of producing magnesium ammonium phosphate.In the whole reaction process is influenced by pH value,reaction...

The paper studied the effect of tide on the removal rate of COD, NH3-N and TP in the dosing pool in order to provide data to simulate disorderly discharged sewage in tidal rivers. Due to the dilute effect of rivers, the removal rate of COD, NH3-N and TP at the tidal state was higher than that at no tidal...

A stripe texture with diameter and spacing of 300 m was prepared on the surface of 304 steel substrate via M-DPSS-50 semiconductor laser marking machine. Then, nitriding treatment on the textured surface was conducted by using well type gas nitriding furnace. The chemical composition, surface morphology...

Electrolytic codeposition technique was adopted in the deposition of NiFe-SiC coating on the stainless substrate, using nickel alloyed with iron as the binder phase with SiC as dispersed particles. The results indicated that the deposit with SiC nanoparticles was level and compact; the crystal-planes...
