This algorithm not only solves the problem that nonlinear and time - variety plant is difficulty to build model , but also decreases the controller calculative burden . it benefits its application to real - time system 该算法不仅解决了非线性时变对象难以建模的问题,而且还减少了控制器的计算工作量,有利于系统的实时应用。
Because mechanic design is a hard and painstaking work , so the traditional mechanic design have many problems , such as the low efficiency , the big calculative error , the waste of manpower and material resources 由于机械设计本身是一项艰苦细致的工作,传统的人工方法进行机械设计存在着设计效率低、计算误差大、浪费人力物力等问题。
In this article , the fisheries management main dimension , such as length , breadth , depth of ship , was analyzed through that have been chosen for morn than ten fisheries management ships , obtaining calculative formulas that related to main dimention 摘要选择十余艘性能优良的渔政船,对其船长、船宽、型深等主尺度做以分析,得出相应的计算公式。
When analyzing the intensity of the drum with the simple numeration and the analogism or the shell theory , the calculative result is not very precise and it " s difficult to describe the nice change of the stress distinctly 采用粗略的简化计算法及类比法或者用板壳理论等方法对滚筒进行强度分析,计算结果不是很精确,应力的细微变化也很难描述清楚。
A three layered magneto - electro - elastic half - space subjected to vertical mechanical loads , charge or magnetomotive force is analyzed as the numerical example , and the calculative results of two different stacking sequences are compared 以在垂直机械载荷或电载荷或磁感应强度作用下三层半无限压电压磁弹性体为算例,并比较了两种不同材料叠放顺序的计算结果。
