纤维形成

Such that ,how to utilize normal dyeing and finishing equipment and detect dyeing and finishing processes of Tencel fabric for local enterprise is very urgent for dyeing and finishing industry of Henan Province.Tencel fiber molecule crack easily to form fibrilla for its special spinning process . In this way, the surface of Tencel fabric will appear a layer of fine staple by the function of wet and mechanical friction.

由于Tencel纤维的特殊纺丝制造工艺，其纤维素分子容易裂开而形成原纤，进而在湿态及机械摩擦作用下，织物表面就会浮出一层极细的短纤毛，其状如"霜白"。

Just little fibrocartilage with on hyaline one was detected in the control group.

Results The tissue engineered tissue from 1 week group is more like fibrocartilage. From 2 week group,the tissue gradually transfer into hyaline cartilage and form more mature hyaline like cartilage in 4 weeks group.

结果：经组织学染色发现：在诱导的初期组织更偏向于纤维软骨，而从第二周开始组织逐渐向透明软骨转化，至第4周逐渐形成成熟的透明软骨样组织。

In this study, we demonstrated that murine BMMSCs, after numerous passages, obtained unlimited population doublings and proceeded to a malignant transformation state, resulting in fibrosarcoma formation in io.

在此研究中我们发现鼠的BMMSCs在多次传代后会具有无限扩增的能力并进入一种恶性转化的状态，导致体内纤维肉瘤的形成。

The purpose was to investigate the effects of metalloproteinases on the development of pulmonary fibrosis.

目的 进一步评价基质金属蛋白酶在肺间质纤维化形成过程中的作用。

Compared with the graphite, the coefficients of friction of the RL-C/C are lower under the same load of about 0.08-0.12, and the increasing range of the volume losses are still lower than those of the graphite. Compared with the SL pyrocarbon material, the COF and the volume loss of the SL-C/C are about 0.02-0.05 and 0.2 mm^3, lower than those under the same load. The COFs of most RL-C/C and SL-C/C specimens remain stable or decrease slightly with time, while those of the graphite and pyrocarbon specimens increase. The thickness of the integrated friction film of the RL-C/C decreases with load, but the wear surface of the SL-C/C is rough. Tough the wear surface of the graphite is integrated, the serious abrasive wear make the debris move easily and accumulate on the edge of the wear trace to form a restacked morphology. On the wear surface of the pyrocarbon material, some loosed debris, circular worn holes and flake worn out pyrocarbon has been found.

结果表明：PAN炭纤维改善C/C复合材料的摩擦磨损行为；在实验载荷范围内，与高强度石墨材料相比，含RL炭C/C复合材料的摩擦因数降低0.08~0.12；体积磨损量增幅降低；与热解炭试样相比，具有SL炭C/C复合材料的摩擦因数降低0.02~0.05，体积磨损量低0.2立方公厘左右；随着时间的延长，大部分C/C复合材料的摩擦因数基本相对稳定或呈小幅下降，而石墨、热解炭块的摩擦因数均呈不同幅度的上升；具有RL炭的C/C复合材料摩擦表面膜厚度随载荷增加而降低，具有SL炭的C/C复合材料摩擦表面较粗糙；高强石墨能形成较完整致密的摩擦膜，但磨粒磨损严重，磨屑易在摩擦膜边缘形成层状堆积；热解炭块摩擦表面磨屑堆积松散，有较多的孔洞以及热解炭层整体剥落的形貌。
