The engineering and research group is concerned with product and material research and product engineering . 设计与研究部门负有产品和材料的研究及产品设计的责任。
Often they were very far from being defined, in so far as the attributes of the plant materials were concerned . 就植物材料的属性来说，它们往往与已规定的还差得很远。
The material fracture toughness was adequate to ensure development of the full fatigue resistance of the weld detail . 材料的断裂韧性可充分满足焊缝细节疲劳抗力的发挥。
The ratio of stress to strain, or the stress per unit strain, is called an elastic modulus of the material . 应力与应变之比，即每单位应变的应力，叫做该材料的弹性模量。
Somewhat related to the condition of the surface are the effects of objects and material picked up by the blast wave . 被爆震波掀起的物体和材料的效应与表面条件有些关系。
By using an incremental approach, the problems involving material or geometric nonlinearity have been solved . 借应用一种增量方法，已经解决了包括材料的或几何的非线性问题。
I would play nasty to arthur's nice, and tell blunt i had serious doubts about the veracity of his confession . 我唱红脸，让阿瑟唱白脸，并且告诉布伦特我对他的交待材料的真实性很有怀疑。
The smaller component does not appreciably affect the larger component's behavior if the volume ratio is large . 只要两者的体积相差很大，则较小部分的材料不会显著影响较大部分的材料的特性。
The major sources of the material in this work can generally be identified despite our slim knowledge of the classical period . 书中材料的主要来源一般都能查到，尽管我们对古典时期所知甚少。
Since that time an effort has been made to catalog the characteristics of each introduction and maintain viable seed . 从那时以后，对编录每个引入材料的特性和保持有生活力的种子作了一定努力。
