查询词典 pulps

By infrared spectra and ultraviolet spectra, mechanism of bio-bleaching was studied preliminarily. The result showed that the content of chromophoric group and lignin in bleached pulps was decreased by enzyme process.

通过红外光谱和紫外光谱研究了生物预处理的漂白机理，结果表明：酶处理可减少漂后纸浆中发色基团和木素的相对含量。

A part of the flat fibers remained on the sheet surface and the interspace among the fibers became narrow after chlorine dioxide bleaching. The fibers of bagasse and bamboo unbleached pulps were rough, the fiber surface was smooth, and the fiber structure was dense. After oxygen delignification and chlorine dioxide bleaching, the fibers became much more thin, the fiber surface was slightly fibrillated, and the fiber structure was loosen.

经氧脱木素后，纸页表面细小纤维明显减少，纤维间空隙较多，而经二氧化氯漂白后的纸页表面保留了一部分形态扁平的纤维，纤维间空隙相对较少；蔗渣和竹子未漂浆纤维较粗，纤维表面光滑，结构密实，而经氧脱木素和二氧化氯漂白后，纤维明显变细，纤维表面轻微帚化，结构较疏松。

After beating, the breaking lengths are 11.9km and 11.5km, and the tear indexes are 5.12 mN·m2/g and 6.56 mN·m2/g for the kraft pulps of Albizia falcataria and Gmelina arborea respectively.

采用硫酸盐法制浆，打浆后南洋楹与石梓浆的裂断长分别为 11.9 km 和 11.5 km；撕裂指数分别为 5.12 mN·m2/g 和 6.56 mN·m2/g。

Comparing Melaleuca leucadendron with Gmelina arborea of the same age, the former has shorter fibers, but the 2 have similar single-fiber strengths. The unbleaehed pulps of the 2 species have comparable composite strength indices.

比较相同二年生速生树种白千层及云南石梓，前者漂白浆纤维较短，但单纤维强度二者相近，且未漂白浆之综合强度指数与同龄级之速生云南石梓材者相若。

The depression of ZLS middlings pyrite has been proved to be successful by way of conditioning PH value of the coal pulps.

通过矿浆PH值的调节，对中梁山中煤中黄铁矿的抑制达到了较好的结果。

Methods: 80 primary molars with deep caries close to the pulps were selected. They were divided into two groups, and operated pulpotomy using formocresol and ferric sulfate respectively. The children were followed up after 6 months and 1 year. Successful rates of pulpotomy were summarized statistically.

选择3~5岁儿童的第一乳磨牙、4~6岁儿童的第二乳磨牙共45人，80颗乳磨牙深龋近髓的病例，随机分为两组，分别行甲醛甲酚和硫酸铁溶液牙髓切断，术后6个月及1年复查，分别统计两组成功率，比较两组的疗效差异。

Abstract］objective: to assess the feasibility of ferric sulfate as a pulpotomy agent in primary teeth.methods: 80 primary molars with deep caries close to the pulps were selected.

摘要］ 目的：探讨硫酸铁溶液作为儿童磨牙牙髓切断术药物的可行性。

These include: a natural rubber liner with brush electrodes for highly abrasive rocky slurry, a polyurethane liner with tungsten carbide-coated electrodes for fine slurries, a high-temperature PFA lining with duplex electrodes for concentrated black liquors, and a hygienic PFA liner with bow electrodes for fruit mashes and pulps.

包括：为磨粉浆所设计的原始橡皮衬里和带刷电极组合；为泥浆设计的聚亚安酯衬里和钨制碳化物表层电极组合；为浓液设计的高温PFA衬里和复式电极组合；以及为水果捣碎和果浆而设计的清洁PFA衬里和弓形电极组合。

而具有较高纤维素酶活力的A10粗酶液处理则导致了纸浆强度性能的降低。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
