（朱加喜） 1、生姜抹腹部:女人在睡觉之前可以选择用生姜来涂抹小腹与肚脐的部位，并且在睡前按摩十分钟，有助于女人在经期缓解痛经的现象。
您好，三缸车普遍提速都慢，为什么？ 三缸车普遍提速慢的原因主要有以下几点： 1. 动力输出不足：三缸发动机相较于四缸发动机输出的动力较小。由于缸数减少，每个缸的排量相对较大，但每个缸的燃烧效率可能较低，导致整体动力输出不足，提速表现较差。 2. 振动和平衡问题：由于三缸发动机的工作原理与四缸不同，存在着不平衡的因素。这可能导致引擎振动和噪音增加，对车辆的提速性能带来负面影响。 3. 扭矩输出不平稳：三缸发动机的扭矩输出可能不如四缸发动机平稳。扭矩输出不平稳会导致车辆在提速时感觉到明显的抖动和不稳定，降低了整体的加速能力。 需要注意的是，不同型号和品牌的三缸发动机在提速表现上可能存在差异。一些高性能的三缸发动机可能通过采用先进的技术和调校来提升提速性能。在购买车辆时，建议和经销商咨询详细的技术参数和性能表现，以了解具体车型的提速性能。你或许或说，那把音量减小不就行了？但声音减小了，自己听起来也是费力，得让听筒紧紧贴住耳朵。 为深入贯彻市委、市政府关于数字经济全面发展的工作部署，太原市大数据应用局日前组织各县(市、区)、开发区数字经济主管部门参加数字经济核心产业常态化监测评价工作专题培训会。
(1-1/2)+(1/2-1/3)+(1/3-1/4)+···+（1/2009-1/2010 To find the sum of the given series, we need to add all the terms together. (1 - 1/2) + (1/2 - 1/3) + (1/3 - 1/4) + ... + (1/2009 - 1/2010) We can simplify each term by finding the common denominator. 1 - 1/2 = 2/2 - 1/2 = 1/2 1/2 - 1/3 = 3/6 - 2/6 = 1/6 1/3 - 1/4 = 4/12 - 3/12 = 1/12 We can observe that each term follows this pattern - the denominator of the second fraction becomes the denominator of the first fraction in the next term. So, the series can be written as: 1/2 + 1/6 + 1/12 + ... + 1/2009 To find the sum of this series, we need to find the common denominator of all the fractions. The common denominator of 2, 6, 12, ..., 2009 will be the least common multiple (LCM) of these numbers. Calculating the LCM of these numbers is a bit lengthy. Instead, we can find the LCM of 2, 3, 4, ..., 2010, and then divide by the LCM of 2, 3, 4, ..., 2009. LCM(2, 3, 4, ..., 2010) / LCM(2, 3, 4, ..., 2009) = 2010 / 2 = 1005 So, the common denominator is 1005. To add the fractions, we need to express them with the common denominator: 1/2 = (1/2) * (1005/1005) = 1005/2010 1/6 = (1/6) * (1005/1005) = 167.5/2010 1/12 = (1/12) * (1005/1005) = 83.75/2010 Now we can add: 1005/2010 + 167.5/2010 + 83.75/2010 + ... + 1/2009 We can observe that the denominators of the fractions form an arithmetic sequence, and the numerators follow the same pattern. Using the formula for the sum of an arithmetic sequence: Sum = (first term + last term) * number of terms / 2 In this case, the first term is 1005/2010, the last term is 1/2009, and the number of terms is 2010. Sum = (1005/2010 + 1/2009) * 2010/2 Sum = (1005/2010 + 1/2009) * 1005 Sum = (1005 * 2009 + 1 * 2010) / 2 Sum = (2019955 + 2010) / 2 Sum = 2021965 / 2 Sum = 1010982.5 Therefore, the sum of the given series is 1010982.5.围绕打造粮食、生猪、肉鸡3条全产业链，引进上下游产业项目16个，其中五得利面粉二期完成制粉车间和麦仓等基础建设； 法官庭后表示，合同僵局是指合同履行过程中因主客观原因的变化，导致合同难以继续履行或合同目的无法实现，违约方欲解除合同，而守约方拒绝解除合同的僵持局面。
