摘要影響高錳酸鹽指數測定準確性的主要因素有樣品酸度、蒸餾水水質、高錳酸鉀溶液濃度、水浴加熱溫度和滴定時間。Under the direction of chinese soil taxonomy, part purple soils developed on the purplish standstones of j2 # j3 in sichuan basin were systematically studiedaccording to natural landscape, profile modality and quick - test, applying to methods statistic analysis and system integration, main affecting factors, indexs of soil series taxonomy and retrieval orders were systematically discussed. the results showed : 1 ) organic substance, total nityogen, total phosphate, total potassium and particle size composition were distinctly related with many soil characters. organic substance, calcium carbonate, available phosphate # size composition were much different in all swatches. besides, soil structure and the depth had profound affection to it. 2 ) affecting factors : soil structure, texture style and organic substance phosphorous
本文以土壤系統分類理論為指導,以四川盆地侏羅系蓬萊鎮組、沙溪廟組和遂寧組紫色巖上發育形成的部分紫色土為研究對象,利用spss統計軟體相關功能,結合供試土壤的自然景觀、剖面形態和室內測定的理化性質,對土系分化的影響因子、土系劃分指標和檢索順序進行了系統的探討,結論如下: ( 1 ) 、供試紫色土中有機質、全氮、全磷、全鉀和顆粒組成與多個土壤性質均呈顯著或極顯著相關;有機質、碳酸鈣、有效磷、顆粒組成等性質在供試土壤方差分析中變異系數均較大;土體構型及土體的深度對土壤性質也有深刻影響。The unconfined compressive strength, shearing strength and permeabi lity of stabilized soils were tested in laboratory, the strength of contaminated composite soils sampled with different ph and soaped in corresponding ph were compared. the results from experiments indicate that there exists a certain relationship between the soft soil properties and the unconfined compressive of grouted soil. with the increase of water content, porosity ratio, degree of porosity, plasticity limit, liquid limit and liquid index, the compressive strength of cement - sodium silicate - stabilized soil decreases, while increases as the bulk weight and compressibility modulus
通過對水泥?水玻璃加固土的無側限抗壓強度試驗,以及用不同酸堿性水製成與養護的固結土所進行強度對比試驗,得出軟土的物理力學性質指標與加固土的抗壓強度之間存在一定的相關關系,即隨著含水量、孔隙比、孔隙度、液塑限及液性指數的增加,水泥?水玻璃加固土的抗壓強度相應地降低;而隨著原狀土的容重、壓縮模量的增加,水泥土的抗壓強度也隨之增加。Through the tests of standard samples, the degree of affecting permanganate index by these 5 factors are investigated
通過環境標準樣品的分析試驗,考察這5個因素對高錳酸鹽指數的影響程度。The parameters used for calculating wqo compliance include ph, suspended solids, dissolved oxygen, 5 - day biochemical oxygen demand, and chemical oxygen demand
用於計算水質指標的參數包括酸鹼度懸浮固體量溶解氧五天生化需氧量及化學需氧量。It was indicated that all of the quality indexes aforementioned were changed with the microwave parameters, and the influence of microwave is directly relevant with the unsarurated fatty acids in the vegetable oils
