Analyses for binder phase distribution and percolative nature as well as effect of progressive substitution HAC byα-alumina on phase composition and distribution in alumina-substituted MDF composites and wet properties suggest that the contribution of the cross-linked PVA located in the interphase region to transport of moisture is limited.
通过加热MDF复合材料至不同温度点分析了其胶结相的分布和渗透特性以及掺加α—A1〓O〓对其相组成、分布和湿性能的影响,结果表明,界面相中交联PVA对湿度传递的贡献是非常有限的,而本体聚合物区域的PVA提供了湿度传递的主要途径,未反应水泥颗粒作为水的接受体,对MDF复合材料的湿抗折性能与吸湿也产生了严重的有害影响。

Results present that when the lateral-torsional coupling is considered, the responses in the lateral direction of the coupled system subjected to a initial disturbance and a harmonic excitation in the torsional direction, respectively, can be occurred in different forms, and show great effects. However the responses in torsional direction subjected to lateral disturbance and harmonic excitation are slightish.
对系统进行了非线性响应数值计算和相应的频谱分析,结果显示弯扭耦合后,在扭转方向的扰动和简谐干扰扭矩均会以不同的形式在弯曲方向表现出来,并对系统的弯曲振动产生较大的影响;而弯曲振动对扭转振动的影响则要小得多。

Geophysical characteristics of Ordovician carbonate rock were studied using drilling data. Impedance is affected mostly by material properties and reservoirs types, to a negligibly extent by lithology and flow. Compact layers and minor\|fracture reservoirs of Ordovician carbonate rock have characteristics of high density, high velocity and high impedance, and the prediction of minor fractures reservoir is difficult by the general seismic ways. Big fractures and fractured\|vuggy and vuggy and cavity reservoirs of Ordovician carbonate rock have characteristics of minor density and low velocity and low impedance in central Tarim basin, which obviously different from the surrounding rock and produce obvious characteristics in seismic data, so reservoirs can be predicted by applying general seismic data.
根据已钻井资料,对塔中地区上奥陶统良里塔格组岩石地球物理特征进行了研究,结果表明:物性、储层类型对波阻抗影响最大,岩性、流体对波阻抗影响较小;奥陶系碳酸盐岩致密层和小裂缝型储层具有密度大、速度高、波阻抗值大的特点,利用地震常规预测手段较难预测出小裂缝型储层,而塔中地区奥陶系碳酸盐岩大裂缝型、裂缝-孔洞型、孔洞型、洞穴型储层具有密度小、速度低、波阻抗值小的特点,与围岩具有较为明显的差异,在地震上可以产生明显的响应,可利用常规地震资料来预测这种类型储层。

In contrast, the postulate that the impact of sunk cost on willingness to continue a project is moderated by risk perception is supported, with results indicating that the lower degree of risk perception will cause greater effect of sunk cost on willingness to continue a project, which will lead to the sunk cost effects more easily. Therefore, the variation in willingness to continue a project as a result of variation in level of sunk cost can be significantly better explained when risk perception is introduced as a moderating factor.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
