Using the approximated differential equation of deflection curve of constant section beam, this paper establishes the analyzing equations of rotating angle and deflection curve under common loads expressed by deflection curve increment (Thus the deflection curve increment of any section of the beam is just the load).
本文应用等直梁挠曲线近似微分方程建立常用载荷作用下梁的转角方程与挠曲线方程用挠曲线增量表示的解析式,其中各段梁的挠曲线增量可用作用于交界面处的载荷表示,初挠度、初转角由梁的支承条件确定。
It is proven by many projects that the predicted settlement using normal hyperbolic method that is incremental hyperbolic method is often less than real final settlement.
工程实践表明,常规双曲线法即增量双曲线法推算沉降往往小于实际沉降,且需要较长时间的沉降资料。
After setting up and comparing the gene capture curves and gene increasing curves,the best sampling proportion of C.
针对濒危植物明党参ISSR数据以及八角莲和夏蜡梅的等位酶数据,以多态位点数(A)、多态位点百分数(PPB)、居群内基因多样度(Hs)、群体总的基因多样度(Ht)、基因分化系数(Gst)以及捕获的基因位点数为主要遗传多样性指标,利用蒙特卡罗模拟抽样法在各抽样比例下重复抽样1000次,并构建了3个植物群体的基因捕获曲线与基因增量曲线。
This paper discusses a method of characterizing the gain of the laser pulse amplifier using its gain fluence curves,and studies gain fluence curves of a single amplifier.
