The signals look like noncontinuous beads on the DNA fiber,which consist of multi-copy and arrange tandemly.Fiber-FISH results with 45S rDNA probe showed that an average signal length is about 3～11μm in many tandem copy sequence(measure number,n=8),so we estimated the size of each copy to be approximately 11～30kb in cotton genome.There are dual signals on each end of the mitosis metaphase chromosomes and pachytene chromosomes hybridized with telomere DNA probe.The signals also look like non-continuous beads on the DNA fiber,the length is about 1～9μm,so we estimated the size is about 4～27kb.The signals almost covered the whole mitosis metaphase chromosomes and pachytene chromosomes of G.arboretum Shixiya 1 hybridized with gDNA probe,the euchromatin zone and heterochromatin zone were identified clearly on pachytene chromosomes,and the signals also look like non-continuous beads.Two BAC clones 150-D-24 and 182-F-9 in DNA BAC library of Pima90 were selected as probe to hybridize with mitosis metaphase chromosomes,pachytene chromosomes and DNA fiber of G.raimondii.

In this thesis, several problems of time-dependent systems in various branches of physics are investigated by making use of the generalized invariant theory and the invariant-related unitary transformation formulation. The problems are given as follows:(1) Spin model and geometric phase factor in the fiber We investigate the fiber experiment performed by Chiao-Tomita and the Chiao-Wu theory concerning the geometric phase factor in the optical fiber, and then show that the investigation of the propagation of photons inside the noncoplanar optical fiber can be regarded as that of a second-quantization spin model.

While the agglutinated nucleus, transfer vesicles, plasma membrane and plasmodesmata still presented.

There was a significant inverse correlation between sarcomere length and A/I (r=-0.686, P.05). 4 Relations of the skeletal muscle histological characteristics and meat quality The muscle fibre and the myofibrils diameter were thinner, the muscle fiber density was denser, the sarcomere length was longer and the meat color was redder. The A/I was bigger, the meat color was whiter, contrarily was redder. The right amount of fat content may improve the meat brightness. The muscle fiber diameter and the myofibrils diameter were the biggest factors to influence the skeletal muscle shearing force, their assumed the obvious linear correlation. The muscle fiber density influence on the shearing force was only inferior to the muscle fiber and myofibrils diameter. Mensurate the IFA from tectology angle may reflect in intramuscular fat content. However intramuscular fat was not enough to carry weight on the shearing force, it may mostly affected on the smack, but not the tenderness expression.

猪骨骼肌组织学特性与肉质性状的关系肌纤维和肌原纤维直径越小、肌纤维密度越大、肌节长度越长，肉色鲜红；肌节中暗带比例越大，肉色偏白，而明带比例大，肉色偏红；适量的脂肪含量可以改善肉的亮度；肌纤维直径和肌原纤维直径对骨骼肌剪切力的贡献率最大，呈明显的线性相关，肌纤维密度对剪切力的贡献率仅次与肌纤维和肌原纤维直径；从组织形态学角度测定肌内脂肪面积比一定程度上可以反映肌肉内的脂肪含量，而肌内脂肪对肌肉剪切力的贡献率比较微弱，对肉食用品质的影响可能更多表现在改善肉的风味，而不是嫩度的表达。
