查询词典 corrasive

Calcium carbonate and soluble glass and so on were confected as alkaline antifouling agent. The Infrared Spectrometry results showed that 2275-2250 cm~(-1) diagnostic absorb wave crest in part A and 3390-3200 cm~(-1) in part B and 1730 cm~(-1) in coating film strongly proved polymers reacted just as the reacting mechanism, that means polysiloxane which offer low-surface-energy property linked Polyurethane system by —OH groups reacting with —NCO groups. Relative molar mass of part A and part B was determined by Gel Permeation Chromatography and the results were appropriate. Surface-energy was determined and results were between 33.6-47.17 mN/m and it increased when alkaline antifouling agent was put into the coating. Alkaline antifouling agent was releasing steadily when the coating film was dipped in seawater. As time gone, the pH value of seawater was increasing. Solubility parameter and results showed that there was no corrasive phenomenon between the polyethylene strand and the coating.

红外光谱分析结果表明，出现在A组分中的2275～2250cm~(-1)处的异氰酸酯特征吸收峰、B组分中的3390～3200cm~(-1)处硅羟基的特征吸收峰及出现在固化后涂膜中的1730cm~(-1)处氨基甲酸酯基团的特征吸收峰证明了涂料成膜物质交联固化符合本文的设计要求，即赋予涂膜低表面能特性的有机硅组分通过—OH基团与—NCO基团的反应已经链接到聚氨酯体系中；凝胶渗透色谱结果表明，成膜物质的A、B组分均为低分子量，符合预聚物的要求；涂膜表面能的测算结果表明，涂膜的表面能在33.6～47.17mN／m之间；加入碱式防污剂后涂膜的表面能略有升高；碱式防污剂的释放平稳，随着涂膜在海水中浸泡时间的增长，pH值有增加的趋势；用溶解度参数原则来评价涂料与网绳的涂装，结果表明，本试验研制的防污涂料对聚乙烯网绳无溶蚀作用。

Corrasive evaluation of groundwater by chemical thermodynamics has developed the technique of corrasive evaluation, which has the guidance significance to engineering practice.

本文在方法上为地下水侵蚀性评价作了有益的探索，并对工程实践具有一定指导意义。

Ccording to the restoration plan of each province in the corrasive region in Loess Plateau, the effect of ecological restoration on grain production in the corrasive region of loess plateau is analyzed.

bstract 根据黄土高原水土流失区有关各省区制定的退耕规划，分析了生态退耕对粮食生产产生的可能影响。

The 147.92×10^4t grain production will decrease in the corrasive region because of the conversion from sloping farming land to forest or grassland.

1生态退耕将直接减少粮食147.92×10^4t，由此退耕还林还草可能会带来粮食产量的暂时下降。

The prediction shows that the total yield in the corrasive region of Loess Plateau in 2010 will reach 1400.71×10^4t. The demand of grain based on the three levels (400kg, 425kg or 450kg/person) will be respectively 1389.34×10^4t, 1470.37×10^4t and 1563.01×10^4t.

3粮食需求预测表明，2010年黄土高原水土流失区粮食总量将达1400.71×10^4t，在人均400kg×10^4t，在人均400kg， 425k和450kg水平下粮食需求分别为1389.34×10^4t， 470.37×10^4t和1563.01×10^4t。

In Project A, grain shortage will not appear in the corrasive region of Loess Plateau on the whole. But in order to achieve an equilibrium of demand and supply, loess hill regions must import grain from the Loess Platform region.

从A方案看，就黄土高原水土流失区整体而言将不会出现粮食短缺；但具体到分区而言，黄土丘陵区必须通过粮食调入才能满足本区需求，而黄土台塬区则有一定盈余。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
