基于BP人工神经网络的膜下滴灌作物水分响应及农田墒情预报模型研究

First , on the basis of production function theory and under CRW hypothesis and CRTS hypothesis , this paper puts forward the method of measuring technical progress bias of Chinese industry .

首先，本文以生产函数理论为基础，在固定规模报酬和固定实际工资率的假定下，给出了技术进步偏向的测定方法。

By this method , the characteristics of CRW flowfield in hover and forward flight are investigated . Also , preliminary investigations are conducted to simulate the flowfield of CRW at transition state .

应用该方法研究了悬停及前飞状态下该飞行器的流场特性，并对过渡状态下的旋翼非定常流场进行了初步的数值分析。

Our previous study showed that recombinant plasmid carrying with human hepatocyte growth factor ( pHGF ) can promote CRW healing , however , the mechanism of promoting CRW healing by pHGF has not completely elucidated .

目的：本实验室前期研究表明，携带人肝细胞生长因子的重组质粒（pHGF）对放创复合伤具有很好的促愈作用，但其促愈机理尚未完全阐明。

At present , however , the researches about the healing mechanism of the combined radiation-wound injury ( CRW ) were limited to the processes of wound healing . The effect of radiation-induced immunomodulation function damage on wound healing is still indefinite .

然而，目前对放创复合伤难愈机制的研究仅限于创伤愈合过程的研究，而辐射所致机体免疫调节功能损伤对创伤愈合的影响尚不明确。

In this thesis , the Canard Rotor / Wing ( CRW ) Aircraft is selected as the object of study . In response to the complicated characteristics of its flowfield , a CFD numerical simulation method for the CRW flowfield is established based on the momentum source model .

以鸭式旋翼/机翼飞行器（CRW）为研究对象，针对CRW复杂流场结构的特点，建立了一套基于动量源模型的鸭式旋翼/机翼飞行器流场及气动特性的CFD分析方法。

With increase of infiltration temperature , the amount of CrW solute increases , which leads to the increase in hardness and breakdown voltage , but the decrease of electrical conductivity and chopping current on the condition of the same Cr content in the CrW / Cu composites .

CrW/Cu复合材料中，对Cr含量相同的配比，随着熔渗温度的升高，基体中CrW固溶体增多，材料的硬度、耐电压强度升高，电导率、截流水平则降低。
