The results showed that : the rate of food consumption and growth , and ecological conversion efficiency tended to decrease with the body weight increase ; with comparison among three diets such as themisto gracilipes , artemia nauplii and fish mud , the result showed that artemia nauplii was very applicable to the ammodytes personatus laboratory experiment ; the experiment of different food size showed that mature artemia nauplii was fitter than larva 在饵料实验中,分别投喂细长脚(虫戎) 、卤虫和鱼糜三种饵料,实验的结果表明:仅管投喂细长脚(虫戎)的生态转化效率比较高,但从玉筋鱼的摄食、生长及与野生的生长相比较来看,卤虫还是室内实验选择的最佳饵料。
Plastic strain first starts from ambient of the porphyroblast , and then develops to rims of porphyroblast and gradually transfers to the centers of porphyroblasts . the brittle remains in the central parts of porphyroblasts come to be decreased through the plastic deformation development , which is accordance with the banding of intensity in many mylonitization zones on wild occurrences and observation in the fabrics of mylonitization rocks under microscope 长石眼球构造的形成主要是由长石与石英的韧性差决定的,塑性变形首先从斑晶的周围部分开始,逐渐向斑晶发展,脆性残斑核不断减小,这与剪切带内糜棱岩化强度分带相一致。
