The chlorine concentrations of lignin in the cell corner middle lamella and secondary wall of chlorinated spruce tracheids and birch fibers were determined by TEM-EDXA technique. 利用透射电镜-能谱(TEM-EDXA)技术定量地测定了氯化过的云杉管胞和桦木纤维的细胞角处的胞间层木素和次生壁木素的氯含量。
The purpose was to study the best printing solid density on secondary fibers newspaper, to realize the control of the image reappearance quality and improve secondary fibers newspaper's performance. 分析了实地密度与图像再现的关系,根据印刷相对反差和色彩反差与实地密度的间接关系,求出二次纤维新闻纸的最佳实地密度范围。
Sr ( NO_3)_2 additive is also beneficial to the preparation of the xonotlite. The globular secondary particles could be seen obviously and the fibers could also be seen clearly by using Sr ( NO_3)_2 as an additive. 原料中加入Sr(NO3)2添加剂后有利于生成硬硅钙石晶体,硬硅钙石二次粒子球形明显,也可以看到明显的硬硅钙石纤维;
The results showed that the HMDS treatment could reduce the Hornification of secondary fibers and enhanced the bonding properties. The strength properties of their papers were improved greatly. 发现经HMDS处理能降低二次纤维的角质化程度,增强纤维的结合力和强度,大大提高纸页的强度性能。

Study on the Ranges of Suitable Solid Densities for Secondary Fibers Newspaper 二次纤维新闻纸最佳实地密度的研究
The status of China ′ s industry including the development of pulp and paper industry based on wood raw material through the integration of forest and paper industries, non-wood raw materials and secondary fibers are introduced. 介绍了我国造纸工业发展木材制浆造纸、走林纸结合发展道路的概况以及非木材纤维原料资源利用情况和二次纤维利用的发展前景。
Hydrolysates of AM-ST Copolymer Emulsions Used for Improving Paper Strength of Secondary Fibers AM-ST共聚物乳液水解产物在再生浆纸张增强中的应用
Effect of Different Cellulase Composition on Secondary Fibers Morphology Ultrastructure 纤维素酶系组成对二次纤维超分子结构形态的影响1
According to the present and previous researches, the authors conjecture that, the secondary fibers of visceral sensation of the pelvic organs originate from the neurons of DCN, IM and lamina I and project into the PBL. 根据本文结果并结合以前的工作推断,盆腔内脏感觉经DCN、IM和Ⅰ层的神经元中继后,投射至PBL。
The origin of the secondary vestibulo-cerebellar fibers in the rabbit& a study with retrograde axonal transport of horseradish peroxidase method 家兔二级前庭小脑纤维的起核&HRP轴突逆行传送法研究
On cellulase treatment, enzymes C1 changed the crytal structure of cellulose chains and made secondary fiber swell, thus, the bonding properties of secondary fibers were improved. 纤维素酶处理时其C1酶破坏纤维素链的结晶结构,使纤维易于润胀,因此增强了二次纤维的结合性能。
In addition, after a secondary treatment the chemical structure of the fibers changed obviously. 二次处理后,纤维表面的化学结构也发生明显的变化。
Influence of Secondary Fibers Newspaper on Multicolor Newspaper Printing 二次纤维配抄新闻纸对彩报印刷质量的影响
The Characteristics of Secondary Fibers in Papermaking 二次纤维的造纸特性
However, polyester fibers are thermoplastic and flammable, when burning they tend to form molten drops, which can bring burns and other secondary damages, so the modification of polyester fibers to improve the performance of anti-dripping has become an interest of extensive research. 但涤纶纤维属于熔融性可燃纤维,燃烧时容易形成熔滴,熔滴易带来包括烫伤等在内的二次伤害,因此对涤纶纤维改性,改善其抗熔滴性能己成为研究的热点。
From above mentioned findings, it is demonstrated that the loss of oligodendrocytes and the secondary injuries cause the demyelination of spared axon in the lesioned spinal cord, which further hampers the neural function of the preserved nerve fibers. 上述研究分析表明,脊髓损后由于继发性损害和少突胶质细胞死亡而造成残留脊髓组织内轴突脱髓鞘改变,影响了存留神经纤维的功能发挥。
