Research on a new type of fly - ash particle strengthening anti - acid material 粉煤灰型粒子增強(qiáng)耐酸膠凝材料的初步研究
In carboxyl acid material vapors , the films had the highest sensitivity to the formic acid vapor 在羧酸類物質(zhì)中又以對(duì)甲酸蒸氣的響應(yīng)靈敏度最高。
The result shows that the burned fly - ash has fine capability of the anti - acid and is practicable to be used in the particles strengthening anti - acid material 實(shí)驗(yàn)結(jié)果表明:經(jīng)過(guò)處理的粉煤灰作為粒子增強(qiáng)耐酸膠凝材料中的耐酸材料具有良好的耐酸性能,用于粒子增強(qiáng)耐酸膠凝材料是完全可行的。
The interaction between sensitive coatings and formic acid vapors was the strongest in the carboxyl acid material vapors , so that the ct - c : h film containing amino - group was the most sensitive to formic acid 在梭酸類物質(zhì)中,甲酸分子的酸性氫鍵最強(qiáng)。故摻胺碳膜對(duì)甲酸蒸氣分子具有最高的響應(yīng)靈敏度。
In order to know about the utilization condition of nitrogen in wheat and rice when fertilize the new long - effect urea that process by humic acid material being used as depressor , the paper study the influence and the best proportion in lime soil that fertilize the new long - effect urea no . 4 to wheat and rice , the result indicate that jointed period is the key period that gramineous crop release the nitrogen 摘要為了了解施用新型長(zhǎng)效尿素時(shí),小麥、谷子氮素的利用狀況,通過(guò)對(duì)冬小麥、春谷子的盆栽試驗(yàn),研究了在石灰性土壤中,以腐植酸類物質(zhì)為抑制劑加工而成的長(zhǎng)效尿素四號(hào),對(duì)小麥、谷子的氮素利用狀況的影響以及最佳配比。
The pollution effects of the plant leaves treated with acid material can be detected quantitatively by means of df . the technique would likely to be applied as a practiced field application with easier operation than chlorophyll fluorescence technique . thus , we conclude that delayed fluorescence is an excellent indicator for evaluating the extent of environment stress on plant 因此,利用植物的光誘導(dǎo)延遲熒光在一定程度上可以檢測(cè)出雨水和空氣中酸性物質(zhì)對(duì)植物葉片的脅迫效應(yīng),該方法比常規(guī)的理化手段更接近于環(huán)境的真實(shí)狀況,而且比葉綠素?zé)晒饧夹g(shù)便于操作。
