let M be (x,y)

then H = (0,y)

OM =(x,y)

PM,HM在OM方向上的投影相等

=> PM.OM/|OM| = HM.OM/|OM|

(OM-OP).OM = (OM-OH).OM

(x-2,y).(x,y) = (x,0).(x,y)

x(x-2)+y^2 = x^2

y^2 =2x

--- Which of the following words has the same sound as the “ed” in the word “danced”?--- Let m

A 试题分析:ed的发音规则是浊辅音和元音后读/d/;清辅音后读/t/ ;d和t后读/id/。Danced中的ed的发音是/t/,而passed中ed的发音也是/t/。所以本题选A。点评:对于ed的发音,既要需要记住发音规则,又要弄清英语字母中哪些是清辅音,哪些是浊辅音的问题。

在计算器中算十位小数点的,结果里会出现e 怎样清除

在计算器中算十位小数点的,结果里会出现e 怎样清除 如果显示只有 E ,说明计算超出范围(也就是溢出)错误。按 C 或 AC 就可以了。如果显示如 2.343256257e-12,则表示 0.000000000002343256257 。 平板电脑有没有使用三十位小数点的计算器 我感觉你用的是float吧,double应该位数会多一点。 但也不会达到30位。因为一个是4字节,一个是8八字节(当然8八字节的64位中不全不都是用来表示精度的,这个意思吧),不是能不能算到30位,而是你接收结果的变量根本装不下30位。 你可以自己实现sin算法,以字符串表示输出结果,这样你要多少位都可以了(只有你愿意等计算的时间) 老实说,如果你真的有必要要这么多位,你或许找专门的数学类工具或语言会比较好。 有没有一种计算器能除开小数点的 手机软件吗?搜索双行计算器。 计算器的话,卡西欧fx-82es即可。 弹弹堂高抛计算器下载能精确小数点的 估算就可以了,没必要那么精准,差距能在0.1到0.4距之间都能打到 为什么计算结果里会出现1.29319E-12 这是科学计数法,意思是1.29319×10^(-12),也就是1.29319×0.000000000001 Unix expr 命令怎么进行小数点计算,返回有小数点的结果 1:使用 expr 外部程式 加法 r=`expr 4 + 5` echo $r 注意! "4" "+" "5" 这三者之间要有空白 r=`expr 4 * 5` #错误 乘法 r=`expr 4 * 5` 带括号的 expr ( 5 - 3 ) * 3 + 1 2:使用 $(( )) r=$(( 4 + 5 )) echo $r 3:使用 $[ ] r=$[ 4 + 5 ] echo $r 乘法 r=`expr 4 * 5` r=$(( 4 * 5 )) r=$[ 4 * 5 ] echo $r 除法 r=`expr 40 / 5` r=$(( 40 / 5 )) r=$[ 40 / 5 ] echo $r 减法 r=`expr 40 - 5` r=$(( 40 - 5 )) r=$[ 40 - 5 ] echo $r 求余数 r=$[ 100 % 43 ] echo $r 乘幂 (如 2 的 3 次方) r=$(( 2 ** 3 )) r=$[ 2 ** 3 ] echo $r 注:expr 没有乘幂 4:使用let 命令 加法: n=10 let n=n+1 echo $n #n=11 乘法: let m=n*10 echo $m 除法: let r=m/10 echo $r 求余数: let r=m%7 echo $r 乘幂: let r=m**2 echo $r 虽然Bash shell 有四种算术运算方法,但并不是每一种都是跨的,建议使用expr。 另外,我们在 script 中经常有加1操作,以下四法皆可: m=$[ m + 1] m=`expr $m + 1` m=$(($m + 1)) let m=m+1 另外,还可以使用bc m=`echo "( $a - 1 )*$b +1" |bc` sql server 计算相除时怎么得到包含小数点的结果 除数或被除数有一个不是整型数据就可以。 如果是常数计算,直接加上小数点和0即可 执行一下,体会一下吧: declare @a decimal(12,4),@b int,@c decimal(12,4) select @a=10,@b=3,@c=3 select @a/@b,@a/@c,@a/3,@b/2.0,@b/2,@c/2,3/2,3.0/2 7÷9十3÷11的计算结果中,小数点的右面100位上的数字是几? 7÷9=0.777…… 商的小数点的右边第100位上的数字是7; 3÷11=0.2727…… 商的小数点的右边第100位上的数字是7。 4020除以六百小数点的题怎么计算 解: 4020÷600 =40.2÷6 =6.7 4020除以六百=6.7 手机计算器两位以上整数相乘为啥出现小数点 1楼错了,1楼只是设置了显示的问题,而没有消除 三种方法、楼主按你想要的取一种: 1、向上取整,即:1.51、1.52、1.53、1.58都取为1.6 F6=ROUNDUP(D6*E6,1) 2、向下取整,即:1.51、1.52、1.53、1.58都取为1.5 F6=ROUNDDOWN(D6*E6,1) 3、四舍五入,即:1.51取为1.5;1.56取为1.6 F6=ROUND(D6*E6,1)

如何去除富文本中的html标签及vue、react、微信小程序中的过滤器

在获取富文本后,又只要显示部分内容,需要去除富文本标签,然后再截取其中一部分内容;然后就是过滤器,在微信小程序中使用还是挺多次的,在vue及react中也遇到过1.富文本去除html标签去除html标签及 空格let richText = " <p style="font-size: 25px;color: white">sdaflsjf的丰富及饿哦塞尔</p><span>dsfjlie</span>";/* 去除富文本中的html标签 *//* *、+限定符都是贪婪的,因为它们会尽可能多的匹配文字,只有在它们的后面加上一个?就可以实现非贪婪或最小匹配。*/let content = richText.replace(/<.+?>/g, "");console.log(content);/* 去除 */content = content.replace(//ig, "");console.log(content);/* 去除空格 */content = content.replace(/s/ig, "");console.log(content);截取字符串content = formatRichText(content);console.log(content);/* 使用substring来截取字符串 */if (content.length > 10) { content = content.substring(0, 10) + "...";}console.log(content);/* 限制字数后添加省略号 */function formatRichText(richText) { let temporaryText = ""; /* 设置多长后添加省略号 */ const len = 142; if (richText.length * 2 <= len) { return richText; } /* 用于记录文字内容的总长度 */ let strLength = 0; for (let i = 0; i < richText.length; i++) { temporaryText = temporaryText + richText.charAt(i); /* charCodeAt()返回指定位置的字符的Unicode编码,值为128以下时一个字符占一位,当值在128以上是一个字符占两位 */ if (richText.charCodeAt(i) > 128) { strLength = strLength + 2; if (strLength >= len) { return temporaryText.substring(0, temporaryText.length - 1) + "..."; } } else { strLength = strLength + 1; if (strLength >= len) { return temporaryText.substring(0, temporaryText.length - 2) + "..."; } } } return temporaryText;}2.vue中使用过滤器filters: { localData(value) { let date = new Date(value * 1000); let Month = date.getMonth() + 1; let Day = date.getDate(); let Y = date.getFullYear() + "年"; let M = Month < 10 ? "0" + Month + "月" : Month + "月"; let D = Day + 1 < 10 ? "0" + Day + "日" : Day + "日"; let hours = date.getHours(); let minutes = date.getMinutes(); let hour = hours < 10 ? "0" + hours + ":" : hours + ":"; let minute = minutes < 10 ? "0" + minutes : minutes; return Y + M + D + " " + hour + minute; }}/* 使用,直接在div中添加就可以了,| 前面的是参数,后面的是过滤器 */<div class="time">{{data.etime | localData}}</div>3.微信小程序中使用过滤器新建.wxs文件var localData = function (value) { var date = getDate(value * 1000); var Month = date.getMonth() + 1; var Day = date.getDate(); var hours = date.getHours(); //计算剩余的小时 var minutes = date.getMinutes(); //计算剩余的分钟 var Y = date.getFullYear() + "-"; var M = Month < 10 ? "0" + Month + "-" : Month + "-"; var D = Day + 1 < 10 ? "0" + Day + "" : Day + ""; var H = hours < 10 ? "0" + hours + ":" : hours + ":" var m = minutes < 10 ? "0" + minutes : minutes; return Y+M + D + " " + H + m;}module.exports = { localData: localData}使用,用<wxs />标签来引入,src为路径,module为引入的文件模块名<wxs src="./filters.wxs" module="tool" /><text class="scoreText">{{tool.filterScore(item.shop.score)}}分</text>直接在.wxml文件中用<wxs></wxs>包裹<wxs module="foo">var some_msg = "hello world";module.exports = { msg : some_msg,}</wxs><view> {{foo.msg}} </view>4.react中使用react中使用,其实就是定义一个方法import noBanner from "@/assets/storeDetail/no-banner.jpg"const filterImg = item => { let bgImg; if (item.shopimages == null) { bgImg = noBanner; } else { bgImg = item.shopimages[0]; } return bgImg;};/* 使用 */ <img src={filterImg(storeitem)} className={style.topImg} alt="" />总结以上所述是小编给大家介绍的如何去除富文本中的html标签及vue、react、微信小程序中的过滤器,希望对大家有所帮助,如果大家有任何疑问请给我留言,小编会及时回复大家的。在此也非常感谢大家对脚本之家网站的支持!

let属于情态动词吗

let不是情态动词,是使役动词。Let,英语单词,及物动词、不及物动词、名词,作及物动词时意为“允许,让;出租;假设;妨碍”,作不及物动词时意为“出租;被承包”,作名词时意为“障碍;出租屋,人名;(缅)莱;(俄)莱特”。单词发音:英式发音[let],美式发音[let]。要点详解:1.let的基本意思是允许对方照其意思而行,引申可表示“出租”“放掉,松掉”等。用于数学中通常表示“假设”。2.let可用作不及物动词,也可用作及物动词。用作及物动词作“出租”解时,可接名词或代词作宾语,也可接双宾语。其间接宾语可以转化为介词to的宾语;作“让、使”解时,通常接以形容词或不带to的动词不定式充当补足语的复合宾语;接动词不定式作宾语补足语时,如用于被动结构, to须保留。let还可接不带to的动词不定式作宾语,这时主要用于某些固定搭配中。3.let用作不及物动词时主要表示“出租”,主语通常为物(如房子等),其主动形式含有被动意义。4.在口语中,let常用于祈使句中表示建议、请求、命令、警告等;在书面语中,可用allow代替let。双语例句:1.I"m blowed if I"m going to let him treat you like that.我绝不会允许他那么对待你。2.Let me just go back to the point I was making.请允许我再回到我刚才所提的观点。3.Let"s take the problems in a different order.咱们换一个顺序来处理这些问题吧。4.Let"s be practical and work out the cost first.咱们实际一点儿,先计算一下成本费用。5.Let"s attack one problem at a time.咱们一次全力处理一个问题。6.I"m not going to let them get one over on me!我决不让他们胜过我!7.It is important not to let things get out of perspective.重要的是不要把事情轻重倒置。8.Let us approach the subject from a different direction.咱们从一个不同的角度来探讨这个题目吧。

let网络是什么

其实很简单!只需要一瓶衣物柔软剂! 操作方法演示 1.准备一桶清水和一块干净抹布; 2.在清水中加入七、八滴衣物柔软剂; 3.将抹布浸入混入衣物柔软剂的水中,拧干后擦拭家具即可。 原理解释 揭秘:平常擦桌子时,因为磨擦会发生静电,吸附空气中的灰尘构成尘土。而柔软剂能够去除静电,就不容易沾染灰尘了。用柔软剂擦洗后,最少能够保持一周左右不沾灰尘。 觉得有用的不要吝啬,多多点赞啦! 来源:健康养生小知识 望采纳谢谢

LET-CAT M1的英文全称是什么?尤其是M1中的那个M

LTE-CAT M1解释:LET-CAT M1,全名LTEUE-Category,拆开来解释:LTE指的是4GLTE网络、UE是指用户设备、Category翻译为等级。通顺解释就是用户设备能够支持的4GLTE网络传输速率的等级,也可以说成是4G网络速度的一个技术标准。M,是Mbps的简写,指最大上行/下行速度。M1,指Downlink(下行)峰值数据速率:1 Mbps,Uplink(上行)峰值数据速率:1 Mbps。LTE-CAT M1用途:LTE Cat M1是专为物联网(IoT)和机器对机器(M2M)通信而专门设计的新型低功率广域(LPWA,low-power wide area)蜂窝技术。它已被开发用于支持低于1Mbps的上传/下载数据速率的低到中等数据速率应用,并且可以在半双工或全双工模式中使用。LTE Cat M1技术能够与2G,3G和4G移动网络共存,因此它具有移动网络的所有安全和隐私功能的优点,例如支持用户身份保密性,实体认证,机密性,数据完整性以及对移动设备鉴定的功能等。

高LET射线中的“LET”是什么意思?

传能线密度(linear energy transfer,LET)常译为线性能量传递,它是描写射线质的一种物理量,单位为J/m,常用keV/μm 表示。高线性能量传递射线简称为高LET (High Linearenergy transfer)射线,系指快中子、质子、...快中子、负π介子、重粒子的LET值高,一般大于10keV/μ,称之为高LET射线

辐射化学里LET是什么意思

  LET全称是Linear Eenergy Transfer,即线性能量传递,是指在单位长度的能量转递。LET是评价射线质的一个参数。在单位长度上电离密度大的LET高,称为高LET射线,反之则称低LET射线。  各种各样的放射线可分为高LET射线和低LET射线。在生物学和肿瘤治疗学上,高LET射线以直接作用为主,是射线直接作用于组织和细胞中的生物大分子,使之发生损伤。其物理特点是具有Bragg峰,生物特点是相对生物效应高,氧增强比低。高LET有各种各样的放射源,其不同源有不同特点,主要有快中子、质子等。低LET射线以间接作用为主,由于机体是处于一个含水很高的环境,射线与生物组织内水分子作用产生自由基,这些自由基再与生物大分子作用使其损伤。低LET射线如X射线、伽玛射线。

自行车倒刹的原理是什么?

倒刹原理:1、普遍的倒刹的后轴比较粗,内部有涨闸 ,飞轮倒转时和后轴有相对运动,内部的机构会顶起闸皮起到刹车作用,飞轮不转动时和向前转动时,刹车机构不会起作用有点像棘轮。2、自行车内部有一个叫做飞轮的结构,它可以使链条逆转时不会带动后轮,从而正常骑行时可以不必一直踩,链条不动时相对正常前进的后轮是逆转的。它是在花鼓内部的,在外面看不到,刹车时候就好比自行车后轮是转动的你用手掌去摸自行车后轮的轮胎,用力越大就好比手掌给它更大的力把后轮磨停下来。3、倒刹花鼓的内部结构就是这么一个简单的道理,它就是类似于就是一块铁片把正在转动的轴心抱死,用力越大就等于给它表面施加压力。扩展资料:在南方人眼里倒刹俗称倒蹬闸,分活飞倒刹,死飞倒刹两种。活飞最初是由德国钻石自行车首创。国产有:青岛金鹿自行车,采用这种刹车方式。平时骑行向前顺时针骑行。需要刹车逆时针踩动脚踏半圈即可刹车。刹车力度取决于采纳力度。它是一种特殊结构的花鼓。目前这种技术及自行车,早就没有了。参考资料来源:百度百科-死飞

空调为什么停电后自己打开呢?怎么解决?

因为空调是带有“记忆”功能的。空调在正常使用过程中如果遇到突然的断电,那么等下次来电的时候,空调的“记忆”功能就会发挥作用,使得空调自动按照断电之前的运转模式继续运转。解决办法:在使用空调中,当出现这种突然断电时,最好的是能够在断电之后把空调的电源插头拔掉,以免出现这种人不在家突然来电空调自启动的问题,费电还可能出现危险;另外,突然断电后再拔掉电源插头,还可以防止雷击天气出现因为雷击导致空调出现故障、或者是突然来电之后一定时间段内电压不稳导致空调电控部件出现的损坏。
