苎麻织物毛羽刺痒感的力学评价 总被引：2，自引：0，他引：2
织物表面硬质毛羽是导致皮肤刺痒的主要因素，本文依据毛羽与皮肤的刺扎作用，建立单纤维轴向弯曲压缩基本模型，并利用改装后的单纤维强力仪，对苎麻纤维刷进行刺扎弯曲实验，验证了纤维束最大压缩强力与纤维形态参数间的基本关系。 相似文献

The goal of this study is to establish a link between fabric fiber features responsible for prickle and peripheral nervous
responses. According to the anatomical mapping of nociceptors and their physiological property, a neuromechanical model coupling
fiber-skin-nociceptor property is developed to stimulate the process of coarse fibers prickling human forearm skin. This model
focuses on the content of coarse edge of fiber ends protruding from fabric surfaces, and the spatial distribution of these
fibers is random. For fiber ends, their diameter and length are assumed to be normally distributed. By systematically changing
the fibers ends per unit fabric surface area, or the distribution of their diameter or their length, we turn to three variables
to measure the resulting neural activity of nociceptors. The results firstly confirmed the highly correction between firing
rates of nociceptors and density of coarse fiber ends. Meanwhile, the firing rates of populations of nociceptors fluctuate
with the density of fiber ends, as implies the probability of coarse fibers triggering nociceptors. Furthermore, the summation
of firing rates over active nociceptors changes with the features of fiber ends in a power law, and closely correlates the
subjective estimate. In theory, therefore, the firing rates of populations of Aδ nociceptors at periphery encode fiber-ends
features responsible for prickle sensation by the spatial and probability integration. 相似文献

Summary For the induction and selection of double mutants with altered starch composition, a uniform (homohistont) amylose-free (amf) monoploid as basic plant is of vital importance. Therefore, newamf monoploids had to be developed via prickle pollination. And 26 monoploids were obtained which were screened in vitro for
vigour, leaf size and for the percentage of monoploid cells. The number of monoploid cells was underestimated at about 28%.
Seven vigorous monoploids were tested in vitro for tuberization capacity, which varied from 0 to 100%. After regeneration
in vitro, 0 to 3.7 adventitious shoots per leaf explant were formed. The tuberization capacity of these shoots varied from
0 to 48. Twoamf monoploids were selected which were vigorous and tuberized well in vitro. They are the basis for the application of an in
vitro mutation breeding protocol that should lead to the induction and selection of new starch mutants in potato. 相似文献

AC Peregrine Red is a maincrop cultivar that produces very uniform attractive tubers with a deep red skin color. Marketable yields and skin color retention in storage are superior to Norland in Canadian and some U.S.A. locations. The cultivar provides the fresh market industry with a high-yielding red-skinned potato, with good storage capacity and resistance to fusarium dry rot. 相似文献

Summary The time-course of wound-induced activity of polyphenol oxidase and its isoenzyme patterns were determined to elucidate a
possible correlation between enzyme profiles and the suberization process. Thin-layer isoelectric focusing of polyphenol oxidase
of suberizing tissues showed a basic similarity of the isoelectric patterns to those of resting tubers, although two new isoenzymes
with low activity appeared and quantitative differences were noted for some of the isoenzymes. Gamma irradiation at a sprout
inhibition does of 100 Gy** did not affect the isoenzyme profiles of suberizing tissues. Skin and cortex tissues showed identical isoenzyme patterns.
Enzyme preparations from skin tissues showed more diphenolase activity than those from the cortex or pith, the last two exhibiting
more monophenolase activity than the skin. No correlation seems to exist between polyphenol oxidase profiles and suberization. 相似文献

Summary A standardised test of skin set (scuff meter) has been used to demonstrate the increase in skin adhesion of six varieties
following haulm destruction. Increases in skin adhesion were characteristically linear in the six varieties but increased
at different rates. At 49 days after haulm destruction, skin adhesion strengths were similar in all varieties except cv. Record
which had a much greater skin adhesion strength. Differences in skin adhesion strength were poorly related to skin morphological
characteristics such as skin thickness, cell size and suberin content. The method of haulm destruction affected skin adhesion
strength with skins adhering more rapidly and more strongly to the tuber following haulm pulling compared with either desiccation
with diquat or mechanical flailing. The method of haulm destruction did not influence skin morphological characteristics. 相似文献
