TBM地区低孔渗高产气储层预测

 本文从TBM地区目的层的地质和地球物理特征分析出发，以三维地震资料为基础，综合利用人工和神经网络波形分类等定性储层预测方法和利用反演及敏感地震属性分析，对TBM地区低孔渗砂岩分布区开展了砂体展布特征分析和天然气高产区预测研究。根据研究结果部署了10口钻井，已完钻的4口井中有3口获得高产气流（其中DK27井日产天然气36.8×10⁴m³）。值得指出的是，目前所用的预测方法还不能预测厚度小于6m的单砂层或砂层组构成的储层。     

低贫铁矿熔融还原炼铁的熔渣用于微晶玻璃制备

以河北司家营铁矿的低贫难选铁矿石为主要原料,研究了采用熔融还原法炼铁和浇铸工艺制备微晶玻璃的可行性,获得了可用于炼钢的生铁原料和建筑装饰用微晶玻璃.利用正交试验设计方法,探讨了不同原料配比组成条件下渣铁分离和熔渣晶化的效果,确定了可用于工业试验的最佳原料配比:铁矿石62%(质量分数,下同),氧化铝粉5%,生石灰15%,萤石3.3%,纯碱8.4%,焦炭6.2%.通过光学显微分析、X射线衍射分析、物理化学性能测试等手段确定了微晶玻璃的物相组成及性能特征.结果表明:在最佳条件下制备的微晶玻璃由硅灰石晶体和玻璃相组成,抗压强度为827MPa,Mohs硬度为6,体积密度2.69 g/cm3,吸水率为0.016%,耐酸性0.08%,耐碱性0.05%.

Scanning electron microscope electron detector with a radial type discrete dynode electron multiplier

A discrete dynode electron multiplier with radial flux of electrons was built and tested in the range of low‐voltage scanning electron microscopy as a backscattered electron detector of topographic contrast. The multiplier collects backscattered electron emitted in a specific range of take‐off angles and over the whole azimuth angular range enabling large solid collection angle. Multipliers with different dynode shapes were studied theoretically with the use of the software for particle optics and three assemblies were built and tested experimentally. The gain estimation, assessment of the type of detected electrons (secondary electron or backscattered electron), imaging the spatial collection efficiency and signal‐to‐noise measurements were performed.     

Surface Hardening of High-Strength Low Alloy Steels (HSLA) Dual-Phase Steels by Ball Burnishing Using Factorial Design

Burnishing is used increasingly as a finishing operation which gives additional advantages such as increased hardness, fatigue strength, and wear resistance. Experimental work based on 3⁴ factorial design was carried out to establish the effects of ball burnishing parameters on the surface hardness of high-strength low alloy steels (HSLA) dual-phase (DP) steel specimens. Statistical analysis of the results shows that the speed, feed, lubricant and ball diameter have significant effect on surface hardness.

低渗透油气藏岩石物性测试方法研究

本文是在已研制的瞬时脉冲岩石物性测试装置与改进的渗透率常规稳流测试装置基础上，分别利用瞬时脉冲方法和稳流测试方法对大量的致密油藏岩们作了渗透率测试实验。相同测试条件下通过对两种方法的对比与统计分析，对低渗透油气藏岩石物性测试的实验方法给予了充分的论证。经大量实验研究表明：在模拟地层压力条件下，瞬时脉冲测试方法与常规稳流测试方法测得的渗透率相对误差极小，通常小于10％，证明这两种方法用于低渗透油气藏岩石物性测试具有较强的合理性。

Peer responses to a team's weakest link: A test and extension of LePine and Van Dyne's model.

This article reports research intended to assess and extend a recent theory of peer responses to low-performing team members (J. A. LePine & L. Van Dyne, 2001a). An instrument that assesses 4 types of peer responses to low performers (compensating for, training, motivating, and rejecting) was developed and then cross-validated in a subsequent study. Results of the study supported the validity of the peer responses measure and were generally consistent with the attributional theory of peer responses. Low-performer characteristics influenced the peer responses. These effects were mediated in part by peer attributions, affect, and cognitions, which explained variance in the peer responses over and above the variance explained by respondents' personality characteristics (i.e., The Big Five).
