AN INVESTIGATION OF THE RELATION BETWEEN COTTON FIBRE PROPERTIES AND YARN QUALITY BY USING HIGH VOLUME INSTRUMENT(HVI)SYSTEM

The objective of this paper is to establish reliable prediction equations relating cotton fibreproperties measured by HVI system and yarn quality,A useful statistical method is adopted for de-veloping a multiple regression model interpreting the relation between the data of Spinlab HVIfibre properties and quality parameters of yarn STQ (Strength Tex Quotient).The percent relativecontribution of a fibre property with respect of STQ is also assessed.The results show that the totalcontribution of the HVI measured fibre properties can account for 77.4% of known variation ofyarn STQ.The main feature of the approach is its flexibility in accommodating all fibre properties.The examination of regression equation showed that it could be well applied to predict STQ ofyarns spun from the same spinning system,but,for different spinning systems and also for yarns ofdifferent linear density,modification of the equation would be needed.     

多元超立方体交换结构信元丢失率仿真分析

研究了多元超立方体交换结构(MHSF)的信元丢失率性能。分析表明，当各交换节点的流量均匀地发送到各个目的节点时，MHSF的信元丢失率d与MHSF的元数k、链路加速因子s、链路缓冲大小m以及节点内部端口数M等因素有关；同时仿真结果显示，在可应用参数范围内，d明显有随着s、m或k(通常M固定)的增加呈指数规律下降的趋势，并且在较小参数条件下MHSF就具有较低的信元丢失率。

中国西周以前织物素材、结构和织具的研究

对西周以前的织物工艺的研究已经不少,但大多比较零散,而且主要着眼于丝绸。本文以迄今为止在中国出土的西周以前典型纺织文物的文献为基础,系统地研究这个时期的织造工艺,包括原料、织物结构、织具。对浙江河姆渡遗址出土的织具零件,结合甲骨文、金文中提示织具的文字,进行了研究。结果显示,所有主要天然纤维已经用上;所有简单和复合的织物组织,除缎纹外,已经出现;所用的织具除已知的原始腰机外可能还有3点或4点支持的地织机。     

不同品种棉花对立枯丝核菌抗性的测定

通过盆栽试验和田间试验证明,棉花不同品种对立枯丝核菌的抗性存在明显差异.新陆早10号、夏9和150-1这3个品种或材料对立枯病的抗性较差,中35、中36、新陆早12号、新陆早9号、新陆早13号等品种对立枯丝核菌的抗性较强.故前者早播若遇持续低温常造成较大面积烂籽、烂芽和死苗,而后者适时早播一般所受损失较小.     

石河子地区棉蚜越冬规律及防治

棉蚜多以孤雌胎生蚜在室内花卉寄主上越冬,冬季窖藏石榴上的棉蚜卵能正常孵化,1月搭起的蔬菜大棚棉蚜末见发生;秋季至冬前,次生寄主棉田棉杆上的有翅孤雌蚜始终保持一定比例,棉田翻田耕后棉杆上棉蚜越冬卵未见存活,而立于地面棉杆上的越冬卵可孵化。下雪丧,原生寄主黄金树上有翅弧雌蚜基本消失,春季原生寄主与次生寄主上棉蚜卵的饱满率及其孵化率均较低。     

Magnetic fabrics in fault-related fold and its relation with finite strain: an example from Mingjiang thrust structures in Western Sichuan

The anisotropy of magnetic susceptibility (AMS) is a quick, effective and sensitive technique used to measure the weakly deformed sedimentary rocks, and also a reliable method to reveal the deforming mechanisms of fault-related folds. In Longmenshan front belt, a typical cross-section of fault-related folds is chosen to study the AMS. A total of 224 oriented specimens have been drilled at 23 different sampling sites which were distributed at the key structural positions of this structural section developed in the Xujiahe formation of the upper Triassic. Six elementary types of magnetic fabrics are recognized and established through this AMS study: 1) a sedimentary fabric; 2) an initial deformation fabric; 3) a pencil structure fabric; 4) a weak cleavage fabric; 5) a strong cleavage fabric; 6) a stretching lineation fabric. It has been found that most of magnetic fabrics are characterized by fabrics of weak deformation which belong to the pure-shear results of a pre-folding layer parallel shortening (LPS). In the fault-bend fold, almost all magnetic fabrics are the initial deformation fabrics of weak deformation, and denote that the deformation in the forelimb is stronger than that in the backlimb and no finite strain is shown in the footwall. While in the fault-propagation fold， finite strains are concentrated in the trishear zone where magnetic fabric results are approximately consistent with the estimated consequences of the kinematic model. The tectonic stress field indicated by the magnetic fabrics is basically the same along the whole structural section and shows a NW to SE compression and shortening which is accordant with the regional compressive stress field of the Longmenshan fold-thrust belt.
