The antifibrillationof Lyocell fibers is treated with vinyl monomer and the degree of fibrillation is estimated by singeing grade.

在实验结果的基础上，提出了碱处理纤维准晶区发生了准晶体解体和晶体再生长的理论假设，并从理论上分析了碱处理纤维聚集态结构的改变。

Almost the same energy was calculated from different residual weights suggesting the decomposition of PBO fiber in air or nitrogen was a single step process.

用热失重方法分析了聚亚苯基苯并二唑纤维在不同气氛中的热分解行为，采用O zaw a法计算了PBO纤维在氮气和空气两种气氛中的热分解活化能。

E and Sirus red in supersaturated picric acid solution;the amount of HA in serum was measured with the method of radiative immunity;the quantitative expression of fibrosis factor—TGF、PDGF was measured with the method of immunity histochemistry.Results:Myocardial collagen in model group increased obviously compared with normal group from the results of electron microscope、H.E、Sirus red in supersaturated picric acid solution.

腹腔注射柯萨奇B3病毒建立病毒性心肌炎慢性期心肌纤维化小鼠模型，随机分为模型对照组、通心络低剂量组、中剂量组、高剂量组，并设正常对照组，用药四周后处死动物通过透射电镜观察心肌细胞超微结构；HE染色、苦味酸天狼星红染色观察心肌胶原数量；放免法测定血清透明质酸的含量；免疫组化染色观察致纤维化细胞因子—转化生长因子和血小板衍生生长因子的定量表达。

Methods:Establish the model of myocardial fibrosis in chronic stage of viral myocarditis by injecting CVB3 into Balb/c rats,divide these rats into model group、Tong xin luo low dose group、Tong xin luo medium dose group、Tong xin luo high dose group and set up normal group,after four weeks of giving medicine execute the animals and observe the ultrastructure of myocardial cell with tramission electron microscope,the quantity of myocardial collagen was observed by staining with H.E and Sirus red in supersaturated picric acid solution;the amount of HA in serum was measured with the method of radiative immunity;the quantitative expression of fibrosis factor—TGF、PDGF was measured with the method of immunity histochemistry.

Firstly, the sisal fiber surface is modified by chemical method, the influence of the kinds and amounts of modified reagents are investigated.

首先，通过化学方法对天然剑麻纤维进行了表面改性处理，考察了改性用的偶联剂种类以及其对纤维改性效果的影响。

The sisal is the perennial leaf fiber crop, and also a kind of hard fiber with the largest amount of consumption and widest range in the world at present.

剑麻是多年生叶纤维作物，也是当今世界用量最大，范围最广的一种硬质纤维。

Much of the work we do these days with elite and amateur athletes is undoing the damage to their stomach muscles from sit ups and other 'core work'. Sit ups and 'core work' overuse the stomach muscles, making them sore and stiff. When this happens, the connective tissue between the muscles develops microfibers to help immobilize and repair the muscles. These microfibers bind the area together so that it can heal.

我们这些天做的工作就是和许多精英运动员和业余选手损坏他们腹肌是从仰卧起坐和"核心工作"过度滥用腹肌，让腹肌变得疼痛发炎，僵硬当这样的事情发生了，在肌肉微纤维直接连接的组织就会帮助修复肌肉，这些微纤维把整片区域盖住了来治愈。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
