假定 1.(姑且认定) suppose; assume; grant; presume; fiction; let; on the supposition (of); on the supposition that 假定 a等于b。 suppose a equals b. 让我们假定另外有一个具有和地球上相似条件的行星。 let us suppose another planet with conditions similar to those on the earth. 假定这是真的 ...。 assuming this to be true ...; 在未听到对他不利的证言之前, 你假定他是无罪的。 you assume his innocence before hearing the evidence against him.2.(科学上的假设, 从前也叫假定) hypothesis 新的发现已证明那个假定是无根据的。 the new discoveries have falsified that hypothesis.3.[数学] assumption; postulation; presumption; 假定成本 assumed cost; hypothetical cost; 假定负债 nominal liability; 假定利息 assumed interest; hypothetical interest; 假定载荷 assumed load; 假定值 assumed value; assumption value; 假定指令 presumptive instruction
Chapter 4 time - dependent computational simulation of the response of cable - suspension feed system in gusty wind based on the time - independent structure finite element method , and with consideration of the movement laws of cabin , a 3 - d time - dependent structure finite element model formulated by a new method named iss method ( instantaneous structure supposition method ) to deal with the vibration response of cable - suspension feed system in gusty wind is presented . in the model , all sources of geometric non - linearity , cable sag and changes of cable geometry due to large displacement , are fully considered 基于时不变结构的有限单元法,在综合考虑馈源舱运动规律的基础上,提出了时变系统的瞬时结构假定法,通过将悬索离散为索杆单元,建立了系统的时变有限元模型,该模型充分考虑了悬索的垂度和大变形等几何非线性因素,应用ne 。
This paper founds mathematical model of twin - floater ocean wave generate electricity device , and analyzes primary parameters on the base of mathematical model for searching the optimal solution during designing this electricity device . it presents the method calculating the ocean wave forces on the several ideal floaters such as cube , vertical cylinder , horizontal cylinder , sphere by the theory that froude - krylow presupposition calculates a big diving body 在研究浮子几何形状与浮子所受波浪力的关系的过程中,本文利用弗汝德-克雷洛夫假定法计算大尺度潜体上的波浪力的思想理论来推导作用在几种常见理想浮体:长方体、垂直圆柱体、水平圆柱体和球体上的垂直波浪力。
