查询词典 freshwater mussel

It was found that 15-g mussel could be completely saponified in 2 min in 30mL of 1mol·L〓 KOH-methanol solution under the optimized microwave heating conditions.

微波皂化迅速彻底，在选定的条件下只需2min即可进行完全。

Experimental results indicated that the contaminants generally existed in mussel, such as α-HCH,β-HCH,γ-HCH,δ-HCH, o·p-DDT, p·p-DDT, p·p-DDD, were degraded completely under the above conditions, whereas DDE, aldrin and dieldrin were partly degraded. No detectable degradation of PCB 1242 and PCB 1248 were observed. Thus the conventional preparation of the contaminants using the columns packed with Florisil or SiO〓 could be left out.

测定贻贝中的PCBs时，以KOH甲醇溶液处理试样，在微波能作用下，试样的微波皂化与有机氯农药的微波碱解同时进行；测定土壤和沉积物中的PCBs时，以KOH甲醇溶液处理试样，在微波能作用下，PCBs的微波萃取与有机氯农药的微波碱解同时进行，1M KOH甲醇溶液对PCBs的微波萃取能力与纯甲醇溶剂相当。

Results show that water in which palm strings are soaked is detrimental to the growth and survival of mussel larvae and that the use of thinner palm strings 3.5-4mm in diameter to weave mattings as collectors instead of thicker ones 6-9mm in diameter previously used can, in terms of decrease in weight of the strings, reduce the adverse effect while at the same time maintaining sufficie

经1972—1973年的研究，我们与烟台地区海水养殖试验场等提出了一套育苗工艺，育苗水体最高单产量达到137万/m~3。又经数年研究，最高单产量即达360万/m~3，平均单产量稳定在150—200万/m~3。再后几年的实验结果，使我们意识到：用原方法育苗要进一步大幅度提高单产量会有困难，特别是近几年来海水水质条件的恶化，有时会给育苗带来一些干

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
