    • 摘要: 【教学设计】教学基本信息学情分析:学生在小学已经学习过简单的几何图形,对几何的认知特点主要表现在:直观几何、经验几何、实验几何,仅仅是对一些简单图形性质的认识,局限于面积和体积的计算。学生进入初中后,首先经历了数系的扩充——从自然数、正分数到有理数,从数到式——有理数到整式,再到一元一次方程,对符号语言有了一定认知。

    • 摘要: 为了研究含油气盆地断裂发育区油气纵向分布规律,在不同方向运移油气过盖层断裂的垂向封闭机制研究的基础上,通过比较泥岩盖层断接厚度与其油源断裂或输导断裂在泥岩盖层内分段生长连接所需的最大断接厚度的相对大小,建立了一套不同方向运移油气过盖层断裂垂向封闭性的预测方法,并将其分别应用于渤海湾盆地冀中凹陷留楚地区东二、三段垂向运移油气过东一、二段泥岩盖层断裂垂向封闭性和文安斜坡沙二段侧向运移油气过沙一段底部泥岩盖层断裂垂向封闭性的预测中,结果表明:留楚地区东二、三段垂向运移油气过东一、二段泥岩盖层断裂垂向不封闭区主要分布在北部留楚背斜核部局部地区和西南广大地区,其余地区为过盖层断裂垂向封闭区.文安斜坡沙二段侧向运移油气过沙一段底部泥岩盖层断裂垂向不封闭区主要分布在东部和中部地区,其余地区为过盖层断裂垂向封闭区.与目前留楚地区东一段、馆陶组和文安斜坡区沙一段已发现油气分布相吻合,表明该方法用于预测不同方向运移油气过盖层断裂的垂向封闭性是可行的.%Objectives:In order to study the vertical distribution of oil and gas in fracture development area of petroliferous basin.Methods:on the basis of the study of vertical sealing mechanism of the migration of oil and gas over fault in different directions,by comparing the relative thickness between the fault thickness of mudstone cap rock and the maximum fracture thickness required by the oil source fault or the fracture of the transporting fault in the mudstone cap formation,a set of prediction methods for vertical sealing of fractured hydrocarbon migration in different directions has been established.They are applied to vertical migration of oil and gas in the Ed2 and Ed3 section of Jizhong depression in Jizhong sag and vertical sealing of the fault of the mudstone in Edt and Ed2 of the Bohai formation and prediction of vertical sealing of bottom mudstone caprock fracture in Es2 of Shahejie Formation in Wen 'an slope.Results:The results show that the vertical non closure area of the mudstone caprock in LiuChu area is mainly distributed in the northern part of the hang anticline core area and the vast southwest area,while the remaining area is the vertical sealing area of the cover fault.The vertical non closed area of mudstone cap rock in Wen'an slope is mainly distributed in the eastern and central parts,while the remaining areas are covered by vertical faults.Conclusions:The oil and gas distribution has been found consistent with the first member of Shahejie formation,the Guantao formation and the 1st member of Shahejie Formation in Wen'an slope area.It is proved that the method is feasible for predicting vertical sealing of faults in different directions of migration oil and gas caprock.

    • 摘要: 根据岩棉条纤维各向异性的特点,研究岩棉条不同方向(纵、横向)的剪切性能(剪切强度和剪切模量),并考虑实际应用,对岩棉条经全浸浸泡处理、高温高湿环境老化处理后的剪切性能进行了研究试验.试验结果表明,岩棉条剪切性能与纤维方向密切相关,纵向剪切强度、模量约为横向的2~3倍,且两者失效模式完全不同.浸泡、老化处理后,岩棉条纵向剪切强度和模量有所降低,横向剪切性能变化不显著.

    • 摘要: In order to study the effects of the faults on the hydrocarbon accumulation and distribution in the welldeveloped fault zone in the petroleum-bearing basin,through research the relationships among the effects for the different-direction oil-gas migration and accumulation,the differences of the hydrocarbon accumulation near the fault were figured out.The achievements show that the differences are shown as follows:for the differently migrated and accumulated petroleum near the fault,the vertically migrated oil and gas are prone to mainly accumulate in the form of the multiple horizons near the transporting fault,while the laterally migrated and accumulated hydrocarbon,the conditions are on the contrary;the different oil and gas are correspond to the different accumulated positions near the fault section,in detail,the vertical is principally accumulated on the upper wall of the transporting fauh,while the lateral is generally enriched on the lower wall of the barrier fauthe planar enriched properties are the same,the vertical is accumulated and distributed along the convex ridge of the transporting fault,while the lateral is done along the transfer zone of the barrier fault.The conducted difference researches on the accumulated characteristics for the different migrated petroleum near the fault have provided a certain guide for the hydrocarbon exploration in the well-developed fault block in the petroleum-bearing basin.%为了研究断裂在含油气盆地断裂发育区油气聚集与分布的作用,通过不同方向运移油气聚集与对油气运聚所起不同作用断裂之间关系分析,对不同方向运移油气在断裂附近聚集特征的差异性进行了研究,结果表明不同方向运移油气在断裂附近聚集特征的差异性主要表现在3个方面:不同方向运移油气在断裂附近聚集层位不同,垂向运移油气在输导断裂附近多层聚集分布,而侧向运移油气在遮挡断裂附近聚集层位相对较少;不同方向运移油气在断裂附近剖面聚集部位不同,垂向运移油气主要在输导断裂上盘聚集分布,而侧向运移油气主要在遮挡断裂下盘聚集分布;不同方向运移油气在断裂附近平面聚集部位不同,垂向运移油气在输导断裂凸面脊处聚集分布,而侧向运移油气在遮挡断裂转换带处聚集分布.开展不同方向油气在断裂附近聚集特征的差异性研究,为含油气盆地断裂发育区油气勘探提供了指导.

    • 摘要: 针对高量程加速度计在测试过程中受高冲击导致测试电路失效从而试验失败的问题,本文运用ANSYS/LS-DYNA对测试电路的焊盘受法向、纵向(与芯片管脚平行)、横向(与芯片管脚垂直)的高冲击力进行了数值模拟,分析和比较了从不同方向冲击PCB板对焊盘可靠性的影响。结果表明,不同方向相同冲击力时,抗冲击能力依次为法向、纵向、横向。研究结果对高量程加速度计的设计具有一定的参考价值。%For the high impact on high-range accelerometer in the testing process ,leading to the failure of test circuit and whole experiment ,this paper uses ANSYS/LS-DYNA to numerically simulate the high impact on the soldering pad of test circuit including normal, vertical (parallel to the chip pin) and horizontal (vertical to the chip pin) .In addition ,this paper analyzes and compares the effect on the reliability of the soldering pads with high impact from different directions. The results show that the soldering pad’s ability to resist impact is normal ,vertical and horizontal in turn. The results of the study have a certain reference value to the design of high-range accelerometer.
