This article chooses different methods of representative scholars which used to study the modulus of elasticity about the periodontal ligament to review 本文就近年来具有代表性的研究牙周膜弹性模量的各种方法作一综述。
The milling cutting tool path creative method of representative part is studied in this paper . we optimized several cutting tool paths of the representative part aiming at little fluctuation of cutting force and high precision of superficial quality 本文针对典型零件的铣削加工,以切削力波动小,表面质量精度高为优化目标对几种刀具运动轨迹进行优选。
With the method of representative investigation and site-specific observation, the effects of different vegetations on water and soil conservation in mengshan mountain were investigated on three aspects : soil melioration, entironment improvement and water and soil conservation 摘要采用典型调查和定位观测的方法,分别从改良土壤、改善环境和保特水土3方面,对蒙山不同植被下水土保持效果进行了调查。
From the angle of uncertainty of inflow and water consumption, the risk of water dispatching on the lower reaches of the yellow river is analyzed . inflow series are generated by use of the method of representative disaggregation . water consumption series are generated according to rainfall probability distribution . a model for risk analysis of water dispatching is established with the technique of stochastic simulation, and a quantitative description of risk is presented, thus, making the water dispatching decision-making more scientific 从来水和用水不确定性角度分析黄河下游水量调度风险.对来水采用典型解集方法生成来水系列,对用水根据降雨概率分布生成用水系列,利用随机模拟技术建立了水量调度风险分析模型,给出风险的定量描述,从而使水量调度决策更加符合实际
