探讨算盘中的易理证实中国珠算的独创性

“中国珠算源于古罗马”的谬说曾在世界流行——这是欧美考证学者的断言，日本一些学者、珠算界权威人士也写文章论证、推断中国算盘从罗马传入。对此．珠算泰斗华印椿老先生以自己渊博的历史知识和科学的论断，发表了《论中国算盘的独创性》，说汉代时“安息人欺骗甘英，使大秦(罗马)与汉隔绝，又限制与大秦贸易在海上进行，使汉商人不能与大秦交往，以达到垄断丝绸贸易、牟取暴利的目的。”“罗马的沟算盘怎幺会由丝绸之路传入中国呢?”“中国算盘由算珠上一下四，有槽无柱，逐步改为上二下五，有柱贯珠，它的结构是独创，而不是来自西方，同罗马沟算盘毫无联系。”     

壳聚糖对SiO2@PDA光子晶体色牢度的影响研究

本文旨在丝绸基底上获得一种结构稳定、色彩明亮的涂层结构。以单分散SiO₂@PDA微球为光子晶体的前驱体，在丝绸上构建SiO₂@PDA光子晶体，通过壳聚糖溶液对结构色丝绸进行后处理，探究不同质量分数的壳聚糖溶液对结构色丝绸色牢度的影响。利用场发射扫描电子显微镜(SEM)观察SiO₂@PDA光子晶体结构的微观形貌，能谱仪(EDS)表征SiO₂微球样品的元素组成，X射线衍射仪表征SiO₂和SiO₂@PDA微球的物相结构，并通过摩擦测试和水洗测试探究结构色丝绸的色牢度。本实验制备的SiO₂和SiO₂@PDA微球粒径大小均一、单分散性良好，SiO₂@PDA光子晶体结构呈周期性紧密排列。与未通过壳聚糖溶液处理的结构色织物相比，在质量分数为3%的壳聚糖溶液后处理下，摩擦测试和水洗测试后结构色脱落较少，仍能保持原来的颜色。实验表明，壳聚糖溶液处理可以有效提高结构色织物的色牢度。     

你是有仓叶新思维的人吗？

真丝针织浸渍工艺的研究

通过浸渍剂HV301和太古油处理后生丝的物理性能的测定，探讨分析了它们对生丝的作用原理，并提出浸渍剂HV301的优越性和可用性，通过HV301浸渍工艺的正交试验，采用计算机处理找出了最佳的工艺参数。研究结果对真丝在针织实际生产中提高效率、保证质量、降低成本有一定的参考价值。     

Mechanical properties of cocoons constructed consecutively by a single silkworm caterpillar, <Emphasis Type="Italic">Bombyx mori</Emphasis>

Most animals have the ability to adapt, to some extends and in different ways, the variation or disturbance of environment. In our experiments, we forced a silkworm caterpillar to spin two, three or four thin cocoons by taking it out from the cocoon being constructed. The mechanical properties of these cocoons were studied by static tensile tests and dynamic mechanical thermal analysis. Though external disturbances may cause the decrease in the total weight of silk spun by the silkworm, a gradual enhancement was interestingly found in the mechanical properties of these thin cocoons. Scanning electron microscopy observations of the fractured specimens of the cocoons showed that there exist several different energy dissipation mechanisms occurred simultaneously at macro-, meso-, and micro-scales, yielding a superior capacity of cocoons to adsorb the energy of possible attacks from the outside and to protect efficiently its pupa against damage. Through evolution of millions of years, therefore, the silkworm Bombyx mori seems to have gained the ability to adapt external disturbances and to redesign a new cocoon with optimized protective function when its first cocoon has been damaged for some reasons.     

丝绸摩擦过的玻璃棒一定带正电吗?

自然界中存在着正负两种电性的电荷已被大家所公认,如何得到这两种电性的电荷呢?无论是现今教材还是其他各种资料上都是采用富兰克林在1747年所提出的命名法:用丝绸摩擦过的玻璃棒带正电,丝绸带负电;毛皮摩擦过的硬橡胶棒带负电,毛皮带正电;不同物体带电性质的不同,由该物体得失电子的难易程度所决定.
