After reviewing the previous dissertation on quantitative characteristic trait of recalcitrant seeds, three aspects of quantitative characteristic trait of seed recalcitrant were defined, which are interspecific aspect, intraspecific aspect and individual developmental aspect. And it was supposed that seed recalcitrance was a compound characteristic, with its core composed of desiccation tolerance, low-temperature tolerance and storage tolerance at least, and its concomitants composed of seed size, 1000-seed weight, moisture content at shedding, non-dormancy, systemic taxonomy, ecological and biochemical aspects. Because these core and concomitants are all gradual, transitional and quantitative, it was inferred that seed recalcitrance was a compound quantitative trait.

文章简要概述了从顽拗型种子到顽拗性种子这样一个对顽拗性种子认识提高的过程，在综述了前人关于顽拗性种子数量性状特征论述的基础上，把种子顽拗性的数量性状特征划分为种间、种内和个体发育三个层面，提出种子顽拗性是一种复合性状，其核心至少包括脱水耐性、低温耐性和贮藏耐性三方面的内容，其伴随性状包括种子尺度、千粒重、初始含水量、休眠特性、分类地位、地理分布和保护性物质含量等多方面的内容，而且这些核心内容和伴随性状的每一个方面都具有渐变的、过渡的、数量型的特征，从而阐明种子顽拗性是一种复合数量性状。

In this paper,we studied the tolerance of Haliotis diversicolor Reeve to high temperature or low salinity .

So chirped fiber gratings have broad reflection bandwidth. The group delay in chirped fiber grating reflection bandwidth changes gradually. These properties are what other type fiber gratings do not have.

所以chirped光纤光栅具有宽的反射带宽，在反射带宽内具有渐变的群时延等其它类型的光纤光栅所不具备的特点。

By employing such a method, 5 series of elastomers, including natural rubbers, elastomeric polyester fibers and ethylene-octene, ethylene-methyl acrylate as well as SIS triblock copolymers, were investigated with the purpose of studying elongation induced phase structure and mobility changes of the samples. For NR samples, it was demonstrated that there exists a small amount of crystals at RT even for unelongated samples. For both NR and the soft segment of PEE, with the increase of elongation ratio, the elongation-induced crystallinity increases almost linearly in a certain region of R, in accord with the increase of the lamellar thickness of the crystals; The behavior of ethylene copolymers, in terms of elongation induced morphorpholgy changes, are quite different from NR and PEE. The crystals are found to be gradually destroyed with the increase of R, with accord with the decrease of the lamellar thickness; The motional behavior of the soft segment of SIS, changes from "liquid" to "solid", in terms of 13C NMR spin-lattice relaxation.For many of the aformented samples, the dependence of 13C spin-lattice relaxtion time T1 on R are different for different groups, indicating that the changes of mobility at MHz frequency region with elongation are different for different groups.

通过对天然橡胶、聚醚酯嵌段共聚物、乙烯-辛烯共聚物、乙烯-丙烯酸甲酯共聚物、SIS等高分子弹性体样品聚集态结构和分子运动的研究，获得了一些新的实验结果，如：给出了确切的实验证据，证明了室温下未拉伸的天然橡胶样品中存在着微量的结晶；发现随着拉伸比增加，天然橡胶及聚醚酯样品的软段部分会出现拉伸诱导的结晶，且结晶度在一定范围内呈现近似线性的增加，所形成晶片的厚度也随之逐渐增加；而乙烯共聚物随着拉伸比的增加，原有的结晶会被逐渐破坏，晶片厚度逐渐变薄，结晶中的缺陷逐渐增加；随着拉伸比的增加，SIS中PI软段部分的核磁共振弛豫行为会出现从液态到固态的转变等；在对上述多个体系的研究中，还发现不同基团的自旋-晶格弛豫时间随着拉伸比呈现不同的变化趋势，表明不同基团的高频运动随拉伸比增加有不同的变化规律。

This would produce a large impact restoring force to straighten well-bore gradually.

A flexible, imaginative performance requires a minute but continuous modification of the metric values printed in the music; it includes color gradation and variety in the use of dynamics, pedaling, and rubato, elements that are indicated in the score only rudimentarily.

灵活的、富于想象力的演奏只是一瞬间，但印刷在乐谱里的音量长度却是在不断地修改；它包括音色的渐变，以及使用力度强弱、踏板和自由节奏时的多样性，乐谱中所标明的基本动作是最初步的。

Then I used a ruler to draw my tapered line on the warped end.
