(2014 德·州高一期末 )将边长为 a 的正方形 ABCD 沿对角线 AC 折起,使得 BD= a,则三棱锥 D -ABC 的体积为 ()23a3A. 12aB.122 3a3C. 4 aD. 6分析:取 AC 的中点 O,如图,则 BO=DO=22 a,又 BD =a,因此 BO ⊥DO ,又 DO ⊥AC,因此 DO ⊥平面 ACB,V D -=1 △ABC3S ABC·DO=1×1× a2×2a=2a3.应选 A. 32212答案:A二、填空题 (本大题共 4 小题,每题 4 分,共 16 分.请把正确答案填在题中横线上 ) 13.以下列图所示, Rt△ A′B′ C′为水平搁置的△ ABC 的直观图,此中 A′C′⊥ B′ C′,B′ O′= O′ C′= 1,则△ ABC 的面积为 ________.分析:由直观图画法例则将△A′ B′ C′复原为△ABC,以下图,则有 BO= OC= 1, AO= 2△11× 2× 2 2=2 2.2.故 S ABC=BC·AO=22答案:2214.已知 A(0,8),B(- 4,0), C(m,- 4) 三点共线,则实数m 的值是 ________.8- 00+ 4分析:k AB== 2,k BC=0+ 4- 4- m∵k AB= k BC,∴m=- 6.答案:- 615.直线 y= 2x+ 3 被圆 x2+ y2- 6x- 8y= 0 所截得的弦长等于________.分析:先求弦心距,再求弦长.圆的方程可化为 (x- 3)2+ (y-4) 2= 25,故圆心为 (3,4),半径 r =5.又直线方程为2x- y+ 3=0,|2× 3- 4+ 3|5,因此圆心到直线的距离为d=4+1=因此弦长为 2r 2- d2= 2× 25- 5= 220= 4 5.答案:4516.已知正四棱锥 O- ABCD 的体积为32,底面边长为3,则以 O 为球心, OA 为半2径的球的表面积为________.分析:此题先求出正四棱锥的高h,而后求出侧棱的长,再运用球的表面积公式求解.V 四棱锥O-ABCD=1× 3×3h=32,得 h=32,32222AC 2186∴OA = h + 2 =4+4= 6.∴S 球= 4πOA2= 24π.答案:24π三、解答题 (本大题共 6 小题,共 74 分.解答时应写出必需的文字说明、证明过程或演算步骤 )17.(本小题满分12 分 )(2015 河·源市高二 (上 )期中 )轴截面为正三角形的圆锥内有一个内切球,若圆锥的底面半径为2,求球的体积.分析:以下图,作出轴截面,由于△ABC 是正三角形,1因此 CD =2AC= 2,因此 AC= 4, AD=23× 4= 23,由于 Rt△AOE∽Rt△ACD,OE CD因此AO=AC.设 OE=R,则 AO= 2 3- R,R1R=23因此=2,因此 3 .2 3-R因此 V球4342 3 3323π=πR =π·3=27. 33323π因此球的体积等于.2718. (本小题满分12 分 )(2015 福·建八县一中联考)已知直线 l : kx- y+ 1- 2k=0(k∈R).(1)证明:直线 l过定点;(2)若直线 l 交 x 轴正半轴于点A,交 y 轴正半轴于点 B, O 为坐标原点,且 |OA |= |OB|,求 k 的值.分析: (1)证明:法一:直线 l 的方程可化为y- 1=k( x-2),故不论 k 取何值,直线l 总过定点 (2,1) .法二:设直线过定点0,y0),(x则kx0-y0+1-2k=0 对随意k∈R恒建立,即 (x0- 2)k- y0+ 1= 0 恒建立,x0- 2= 0,因此-y0+ 1= 0解得 x0=2, y0= 1,故直线 l 总过定点 (2,1).(2)由于直线l 的方程为y= kx- 2k+ 1,1则直线 l 在 y 轴上的截距为1- 2k,在 x 轴上的截距为2-k,依题意 1- 2k= 2-1> 0,解得 k=- 1 或 k=1k2( 经查验,不合题意 )因此所求 k=- 1.19. (本小题满分 12分 )(2015 西·安一中期末 )已知正方体ABCD - A1B1C1D1, O 是底面ABCD 对角线的交点.求证: (1)C1O∥平面 AB1D 1;(2)A1C⊥平面 AB1D 1.证明:(1)连结 A1C1,设 A1C1∩ B1D1=O1,连结 AO1,由于 ABCD -A1B1C1D1是正方体,因此 A1ACC1是平行四边形,D1 B1∩ AB1= B1,因此 A1C1∥AC,且 A1C1=AC ,又 O1, O 分别是 A1C1, AC 的中点,因此 O1C1∥AO 且 O1C1= AO,因此 AOC1O1是平行四边形,因此 C1O∥AO1, AO1? 平面 AB1D 1,C1O?平面 AB1D 1,因此 C1O∥平面AB1D1,(2)由于 CC1⊥平面 A1B1C1D1,因此 CC 1⊥B1D 1,又由于 A1C1⊥B1D 1,因此 B1D 1⊥平面 A1C1C,即 A1C⊥B1D1,同理可证 A1C⊥AB1,又 D1B1∩ AB1=B1,因此 A1C⊥平面 AB1D 1.20. (本小题满分12 分 )求圆心在直线y=- 2x 上,而且经过点A(0,1) ,与直线x+ y=1相切的圆的标准方程.分析:由于圆心在直线y=- 2x 上,设圆心坐标为( a,- 2a),则圆的方程为(x- a)2+(y+ 2a)2= r2,圆经过点 A(0,1)且和直线x+y= 1 相切,2+ 2a+122a=r ,因此有|a- 2a- 1|= r ,212解得 a=-3,r=3,12222因此圆的方程为x+3+ y-3=9.21.(本小题满分13 分 )以下图,在四棱锥V- ABCD 中,底面 ABCD 是正方形,侧面VAD 是正三角形,平面VAD⊥底面 ABCD .(1)求证: AB⊥平面 VAD;(2)求平面 VAD 与平面 VDB 所成的二面角的大小.分析:(1) 证明:∵底面 ABCD 是正方形,∴AB⊥ AD .∵平面 VAD⊥底面 ABCD ,平面 VAD∩底面 ABCD = AD, AB⊥ AD, AB? 底面 ABCD ,∴AB⊥平面 VAD.(2)取 VD 的中点 E ,连结 AE , BE.∵△ VAD 是正三角形,∴ AE ⊥ VD , AE = 3AD.2∵ AB ⊥平面 VAD ,VD ? 平面 VAD ,∴ AB ⊥ VD .又 AB ∩ AE = A ,∴ VD ⊥平面 ABE.∵ BE? 底面 ABE ,∴ VD ⊥ BE.∴∠ ABE 就是平面 VAD 与平面 VDB 所成的二面角的平面角.在 Rt △BAE 中, tan ∠ BEA =BA= AD=2 3.AE332 AD∴平面 VAD 与平面 VDB 所成的二面角的正切值为233.22.(本小题满分 132 2上的动点,点 D 是 P分)如图,设 P 是圆 x + y = 25 在 x 轴上的投影, M 为 PD 上一点,且 |MD |= 4|PD |.5(1)当 P 在圆上运动时,求点 M 的轨迹 C 的方程;(2)求过点 (3,0) 且斜率为 4的直线被 C 所截线段的长度.5分析: (1)设 M 的坐标为 (x , y), P 的坐标为 (x p , y p )p = xx由已知得, y p =5y4252∵P 在圆上,∴ x + 4y= 25,即 C 的方程为 x 2 + y 2= 1.25 164 4(2)过点 (3,0)且斜率为 5的直线方程为 y = 5(x - 3),设直线与 C 的交点为 A(x 1, y 1) , B(x 2 ,y 2)4将直线方程 y = 5(x -3) 代入 C 的方程,得 x 2+ x - 3 2= 1 整理得 x 2- 3x - 8= 025253- 413+ 41∴x 1=,x 2=22∴线段 AB 的长度为|AB|=x1- x22+ y1- y22162=1+25x1- x24141=25× 41=5 .。

装配式建筑施工中的模块质量检测与验收标准概述随着建筑业的发展,装配式建筑施工方式成为一种快速、高效且环保的选择。

然而,在装配式建筑项目中,模块质量的检测与验收显得尤为重要。

本文将介绍装配式建筑施工中常见的模块质量检测与验收标准。

一、设计前的准备工作在进行模块质量检测与验收之前,需要进行相关准备工作。

首先,编制详细的施工方案和设计方案,明确装配式建筑的具体要求和技术指标。

其次,订购合格的施工材料,并确保供应商提供符合国家标准的证明文件。

二、加强生产过程控制1. 材料检测在开始生产之前,对所有使用到的材料进行严格检测是必要的。

例如,钢结构模块需要进行金属材料化学成分分析、力学性能测试等,以确保其满足设计要求。

2. 制造过程监控制造过程中需要加强监控,包括对连接部位焊接强度、防水层施工等进行质量检查。

同时,应制定严格的质量控制方案,并确保每道工序符合相关标准和要求。

三、模块装配前的质量检测1. 尺寸检测在模块装配前,需要对关键尺寸进行精确测量。

包括板材长度、宽度和厚度等参数的测量,以及墙体或楼层之间连接方式的准确度检验。

2. 焊接连接强度测试对于焊接结构部分,需要进行焊缝检测以验证其强度是否满足标准要求。

常用的测试方法包括超声波探伤和磁粉探伤。

3. 材料性能测试不同类型的模块需要进行不同的材料性能测试。

例如,板材可以通过弯曲试验、冲击试验等来评估其力学性能;防水层可通过水密性测试和耐候性测试来评估其质量。

四、模块装配后的验收标准1. 外观检查模块安装完成后,首先进行外观检查。

包括模块表面是否有划痕、裂纹、氧化等问题,以及颜色是否一致。

工业自动化模块的质量控制和检测技术

工业自动化模块的质量控制和检测技术

工业自动化模块的质量控制和检测技术随着企业的迅速发展,自动化技术已经成为工业生产的重要组成部分。

自动化生产线的模块化设计不仅使工艺流程更加高效,同时也让设备维护更加简便。

工业自动化模块的质量控制和检测技术已经成为生产线稳定运行的关键因素之一。

本文将从模块质量控制和检测技术两方面进行分析。

一、模块质量控制技术在工业自动化生产线中,模块质量对于整个生产线的稳定性和可靠性影响非常大。

因此,质量控制技术也变得至关重要。

1.质量监管标准首先,企业需要制定自己的质量监管标准,并遵循相关的质量控制规程进行质量检查。

模块生产的过程中,需要建立统一的质量监管机制,包括对原材料、过程、成品等各环节的严格控制和检查,保证每个环节的质量都符合企业的标准。

2.检测技术模块质量的检测是质量控制的重要环节。

检测技术既包含对外观的检查,也包含对电气电子性能的检验。

对于模块的外观,应该根据企业的标准进行检查,判断是否存在缺陷、异物、变形、渗漏等问题。

对于电子电气性能,需要进行电气参数测试、抗干扰性能测试、耐压测试等,判断模块的性能是否符合要求。

二、模块检测技术自动化模块的检测技术也非常重要。

在生产线运行过程中,模块的故障会影响整个生产线的正常运行,对企业造成不同程度的损失。

因此,采用有效的检测技术对模块进行严格的检测,可以帮助企业及时发现问题,缩短故障排查的时间,提高生产效率。

1.可视化检测可视化检测技术是通过图像处理技术来对模块进行自动检测。

通过对模块零部件的图像进行处理与比对,分析图像中部件的位置、颜色、形状等,并与标准图像进行比对,从而判断模块的装配是否合格。

可视化检测技术可以大幅度提高检测效率和准确性,缩短检测周期,同时还能够避免人为因素对检测结果的影响。

2.电子设备检测技术采用电子设备检测技术可以有效地检测模块的电气电子性能是否正常。

电子设备检测技术主要包括电气参数测试、电子元器件功能测试、耐压测试、抗干扰性测试等。

通过对模块进行全方位、多角度的检测,能够有效地预防模块故障的发生,提高生产效率和质量。

装配式建筑施工中模块化装配质量检测与验收准则

装配式建筑施工中模块化装配质量检测与验收准则

装配式建筑施工中模块化装配质量检测与验收准则随着技术的进步和人们对于建筑的需求不断提高,装配式建筑逐渐得到了广泛应用。

在装配式建筑施工过程中,模块化装配是其中一个重要环节。

然而,由于其特殊性和复杂性,模块化装配质量检测与验收显得尤为重要。

本文将就这一话题展开讨论。

一、模块化装配质量检测1.1 结构强度检测在模块化装配过程中,结构的稳定性和强度是首要考虑因素。

因此,在进行质量检测时应注重以下几个方面:1.1.1 材料强度测试包括钢结构、混凝土等材料的抗压、抗拉等强度测试。

1.1.2 连接件质量测试包括螺栓连接、焊接等连接方式的牢固性测试。

1.1.3 功能零部件测试对于各功能零部件(例如门窗、水电设备)都需要进行相应的功能性能及可靠性测试。

1.2 模块一致性检测为确保模块化装配后的建筑整体性和外观效果,对于各组件之间的尺寸、色彩等方面应进行一致性检测。

这包括但不限于以下内容:1.2.1 尺寸精度检测包括模块化装配的各组件的尺寸精度测试,确保其相互之间符合设计要求。

1.2.2 色彩一致性检测如需颜色统一,应进行颜色差异测试和色差控制。

1.3 防水及隔热性能测试模块化装配建筑中,防水和隔热是关键因素。

因此,在质量检测中需要注重以下方面:1.3.1 防水性能测试包括墙体、屋顶等部位的防水效果测试,确保装配后的建筑具备良好的防水性能。

1.3.2 隔热性能测试包括墙体、窗户等部位的保温效果测试,确保装配后的建筑具备良好的隔热性能。

二、模块化装配质量验收准则2.1 结构完整性验收模块化装配后,需要对整个建筑结构进行整体验收,确保其完整性和稳定性。

验证以下几个方面:2.1.1 模块连接验收对各模块之间的连接方式、连接牢固度等进行验收。

2.1.2 主体结构验收对主体结构的拆装便利性、耐久性等进行验收。

2.1.3 功能零部件验收包括门窗、水电设备等功能零部件的安装效果和质量。

2.2 灾害抵御能力验收根据建筑所在地的气候条件及设计要求,对装配式建筑具备的抵御自然灾害能力进行检测和评估。

产品质量检测中的可靠度和精确度要求

产品质量检测中的可靠度和精确度要求

产品质量检测中的可靠度和精确度要求在如今竞争日益激烈的市场上,产品质量成为了各个行业中最为关注的问题之一。

而为了保证产品的质量,产品质量检测就显得尤为重要。

在进行产品质量检测时,可靠度和精确度则成为了两个非常重要的要求。

可靠度是指在特定环境下,产品的期望性能能够长时间稳定地保持下去。

可靠度是产品在正常使用环境中连续运行的概率。

例如,当我们购买一台电视时,我们希望它能够长时间使用而不出现故障。

因此,在对电视进行质量检测时,我们需要测试其中的各个功能模块的可靠性,如画面质量、音效等。

如果产品在测试中得出的可靠度很高,那么我们就可以认为这款电视是值得购买的。

另一方面,精确度则是指产品质量检测结果与真实情况的接近程度。

在进行质量检测时,我们需要确保测试数据的准确性。

如果测试结果无法准确反映产品的真实质量情况,那么就会给消费者带来误导和不良的购买体验。

以食品质量检测为例,为了保证食品的安全,在检测中要求对其中的重金属、农药残留等有害物质进行测试。

如果食品检测结果显示有害物质含量在国家规定的标准范围内,那么我们就可以认为该食品是精确无误的。

要保证产品质量检测中的可靠度和精确度,我们需要依靠合适的检测方法和先进的设备。

例如,在电子产品质量检测中,我们可以使用专业的测试仪器和设备来进行各个功能模块的测试。

而在食品质量检测中,可以采用现代化的分析方法,如质谱仪和色谱仪等仪器进行含量的分析检测。

这些设备具有高度的自动化和精确度,能够大大提高检测的可靠度和精确度。

此外,对于产品质量检测人员来说,专业的知识和技术也是不可或缺的。

只有具备专业知识和丰富经验的检测人员,才能够准确判断测试结果,并提供正确的产品质量评估。

因此,加强培训和提高专业素质,对于保证产品质量检测中的可靠度和精确度是至关重要的。

总结起来,产品质量检测中的可靠度和精确度要求是保障产品质量的基础。

只有在可靠度高且精确的检测结果下,消费者才能放心购买并信赖产品。

2022_2023学年新教材高中语文模块综合质量检测部编版选择性必修下册

2022_2023学年新教材高中语文模块综合质量检测部编版选择性必修下册

模块综合质量检测(时间150分钟 满分150分)一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,19分)阅读下面的文字,完成1~5题。

材料一:古代文学上,“文学自觉”指的是文学创作主体意识到文学的独立性和价值性,自觉地对文学的本质和发展规律等进行探讨和认识,促进文学按其自身的规律向前发展。

根据当代学者胡旭的研究,中国文学自觉有以下标志:标志之一是张衡《归田赋》的出现。

张衡曾用十年时间写成《二京赋》。

该赋的主旨是讽谏帝王公侯节俭,但这篇花费巨大精力所作的大赋,于政教却丝毫无补。

面对着朝政日非、江河日下的局面,其道家思想开始抬头。

《归田赋》中表现了隐居生活的恬淡情趣。

赋中分明已有一个抒情主人公在,自我意识加强了,个人价值得到了关注。

此后,抒情小赋不断出现,辞赋成了文人抒情写意的工具,实现了文学的自觉。

标志之二是“古诗十九首”的出现。

大约在桓、灵之世,出现了一批文人五言诗,其代表就是选录于《昭明文选》的“古诗十九首”。

古诗在内容上表现了“人的自觉”。

“十九首”的内容不外游子之歌和思妇之词两个方面,诗人们慨叹人生的短促和前途的渺茫,抒写了羁旅愁怀和离别相思,情调是悲哀而深沉的,这些慨叹正是对人生的执着与重视。

“古诗十九首”的抒情十分真实强烈,作者们对自己的种种情感,毫不掩饰,一寄之于诗。

这说明古诗的作者们不再把文学作政教的附庸,而是为满足自己的抒情需要进行创作;人的主题鲜明了,文学成了表现人生、人的命运、人的心灵的文学。

标志之三是散文创作方面新面貌的出现。

首先是各体散文的长足发展。

以文体而言,碑、铭、诔、箴、书、笺、檄、策、令、议、记、嘲、谒文、连珠等,种类繁多。

其次,东汉中后期散文逐渐趋向整齐华美。

一是在句式、音节、辞藻、用典等方面做文章,着力创造出一种形式美;二是讲究散文风神的飘逸与灵动。

(摘编自“百度百科”,有删改)材料二:鲁迅先生在《魏晋风度及文章与药及酒之关系》的演讲中指出“用近代的文学眼光来看,曹丕的一个时代可说是‘文学的自觉时代’”,其本意为嘲讽新月派与创造社“为艺术而艺术”的文学主张,孰料这一讽喻时事、有感而发的观点竟在传播中异化,“魏晋文学自觉说”在学界影响愈加广泛。
