A. CVT變速箱比傳統AT變速箱省油嗎為什麼
從自動變速箱的類型來看油耗,CVT變速箱確實相對是比較省油的,還有雙離合變速箱也是如此,而AT變速箱的油耗高不高得看是幾AT,比如以前的4AT和現在主流的6AT,在油耗上比CVT確實要高一些,但是8AT、9AT實際上和CVT的油耗已經差不多了,這是由於變速箱的結構以及工作原理造成的。
綜上所述,CVT變速箱之所以省油是因為可以做到無級變速,總能用最佳的擋位來行駛,由於現在8AT、10AT對應的擋位也不少了,所以同樣會起到省油的作用,而CVT省油主要是與6AT、4AT相比,與8AT、10AT相比省油的優勢就不明顯了。
B. 英語中的had,was,were分別用在什麼情況下
had是have的過去式就用在一般過去式的句子中eg:Ihadabeautifulwatch.
was是be動詞is的過去式be動詞一般都構成系表結構後面可以加形容詞或者副詞還可以加動詞ing表示進行等等具體要看時態eg:Iwasalittlegirltenyearsago.十年前我是個小女孩。
were是are的過去式be動詞分別是amisare第一人稱單數後面接am第二人稱單數,復數第三人稱復數都用are(you是你,你們的意思)第三人稱單數就用iseg:。
She had her portrait painted.
她讓人給自己畫了像。
He was fined 200 dollars.
他被罰款200美元。
He is, as it were, a walking dictionary.
他可說是個活字典。

四. 語法知識
特殊疑問句通常以「what」、「who」、「which」、「when」、「where」、「how」、「how old」、「how many」等開頭,對某一具體問題進行提問。
特殊疑問句的基本構成有兩種情況:
1. 疑問句+一般疑問句結構。這是最常見的情況。例如:
What』s your grandfather』s telephone number? 你爺爺的電話號碼是多少?
Who is that boy with big eyes? 那個大眼睛的男孩是誰?
Which season do you like best? 你最喜歡哪個季節?
When is he going to play the piano? 他什麼時候彈鋼琴?
Where does he live? 他住在哪兒?
How are you? 你好嗎?
How old are you? 你多大了?

2. 疑問句+陳述句結構。這時疑問詞作主語或修飾主語。例如:
Who is on ty today?
今天誰值日?
Which man is your teacher?
哪位男士是你的老師?
我們學過的What/How about+名詞/代詞+其他?也是特殊疑問句,它是一種省略結構。
例如:
I like English. What/How about you? 我喜歡英語。你呢?
What about playing basketball? 打籃球怎麼樣?

① What + is / are + sb?
② What + does/ do + sb + do?
③ What + is/ are + 名詞所有格/ 形容詞性物主代詞 + job?
2 People give me their money or get their money from me.

D. 前端開發的基本方法
CSS部分
盒子邊傾斜
clip-path: polygon(12% 0, 100% 0, 100% 100%, 0 100%);
禁止點擊事件/滑鼠事件「穿透」
div * { pointer-events: none; /*鏈接啊,點擊事件啊,都沒有效果了*/ }
用來控制元素在移動設備上使用滾動回彈效果
.main{
-webkit-overflow-scrolling: touch;
}
可解決在IOS中使用overflow:auto 形成的滾動條,滾動不流暢的情況
文字漸變效果
.text-gradient{ background-image: linear-gradient(135deg, deeppink, deepskyblue);
-webkit-background-clip: text; color: transparent;
}
css三角形
#triangle-up { width: 0; height: 0; border-left: 50px solid transparent; border-right: 50px solid transparent; border-bottom: 100px solid red;
}
實現圓弧
clip-path: ellipse(80%60% at50%40%);
JS部分
JavaScript中檢測數組的方法
(1)、typeof操作符
這種方法對一些常用的類型檢查沒有問題,但對array和null 都判斷為object
(2)、instanceof操作符
這個操作符是檢測對象的原型鏈是否指向構造函數的prototype對象的
(3)、對象的constructor屬性
const arr = []
console.log(arr.constructor === Array) // true
(4)、Object.prototype.toString
constarr=[]console.log(Object.prototype.toString.call(arr)==='[objectArray]')//true
(5)、Array.isArray()
常用的字元串操作
字元串轉化toString()
字元串分隔split()
字元串替換replace()
獲取長度length
查詢子字元串 indexOf
返回指定位置的字元串或字元串編碼 charAt charCodeAt
字元串匹配 match
字元串拼接concat
字元串的切割或提取slice() substring() substr()
字元串大小寫轉化 toLowerCase toUpperCase
字元串去空格 trim() 用來刪除字元串前後的空格
- const str = '11122223333'const uniqueStr = [...new Set(str)].join('')
- arr.rece(callback,[initialValue])
- 跳過第一個索引。如果提供initialValue,從索引0開始。
- const arr = [1, 2, 3, 1, 2, 3]const uniqueArr = [...new Set(arr)]
- var a = {};Object.defineProperty(a, 'name', { value : 'kong', enumerable : true //該屬性是否可枚舉})
- function a(){}
- var b = new a();console.log(a.prototype.isPrototypeOf(b));//true
- if (/Android/gi.test(navigator.userAgent)) { window.addEventListener('resize', function () { if (document.activeElement.tagName === 'INPUT' || document.activeElement.tagName === 'TEXTAREA') { window.setTimeout(function () { document.activeElement.scrollIntoViewIfNeeded();
- }, 0);
- }
- });
- };
- /**
- * 向URL追加參數
- * @function stringifyUrlArgs
- * @param {string} url - URL路徑
- * @param {object} params - 參數對象
- * @return {string}
- const stringifyUrlArgs = (url, params) => {
- url += (/?/).test(url) ? '&' : '?'
- url += Object.keys(params).map(key => `${key}=${params[key]}`).join('&') return url
- }
- /**
- * 解析URL參數
- * @function parseUrlArgs
- * @param {string} url - 字元串
- * @return {object}export const parseUrlArgs = url => { const arr = url.match(/([^?=&]+)(=([^&]*))/g) || [] const args = arr.rece((a, v) => {
- a[v.slice(0, v.indexOf('='))] = v.slice(v.indexOf('=') + 1) return a
- }, {}) return args
- }
- NP.strip(num) // strip a number to nearest right numberNP.plus(num1, num2, num3, ...) // addition, num + num2 + num3, two numbers is required at least.NP.minus(num1, num2, num3, ...) // subtraction, num1 - num2 - num3NP.times(num1, num2, num3, ...) // multiplication, num1 * num2 * num3NP.divide(num1, num2, num3, ...) // division, num1 / num2 / num3NP.round(num, ratio) // round a number based on ratio
其中第9中三者的區別如下:
(1)slice(), 參數可以是負數,負數表示從字元串最後一個位置開始切割到對應結束位置
(2)substring(),參數不可為負數,切割第一個位置到第二個位置的字元串
(3)substr(), 參數可以是負數,第一個參數是開始位置,第二個參數為切割的長度
字元串去重
常用的數組操作
1、Array.map()
此方法是將數組中的每個元素調用一個提供的函數,結果作為一個新的數組返回,並沒有改變原來的數組
2、Array.forEach()
此方法是將數組中的每個元素執行傳進提供的函數,沒有返回值,注意和map方法區分
3、Array.filter()
此方法是將滿足條件的元素作為一個新數組返回
4、Array.every()
此方法將數組所有元素進行判斷返回一個布爾值,如果所有元素都符合判斷條件,則返回true,否則返回false
5、Array.some()
此方法將數組所有元素進行判斷返回一個布爾值,如果有一個元素滿足判斷條件,則返回true,所有元素都不滿足則返回false
6、Array.rece()
此方法為所有元素調用返回函數
7、Array.push()
在數組最後面添加新元素
8、Array.shift()
刪除數組第一個元素
9、Array.pop()
刪除數組最後一個元素
10、Array.unshift()
在數組最前面增加元素
11、Array.isArray()
判斷是否為一個數組
12、Array.concat()
數組拼接
13、Array.toString()
數組轉化為字元串
14、Array.join()
數組轉化為字元串,並用第一個參數作為連接符
15、Array.splice(開始位置,刪除個數,元素)
其中rece使用方法為:
callback (執行數組中每個值的函數,包含四個參數)
1、previousValue (上一次調用回調返回的值,或者是提供的初始值(initialValue))
2、currentValue (數組中當前被處理的元素)
3、index (當前元素在數組中的索引)
4、array (調用 rece 的數組) initialValue (作為第一次調用 callback 的第一個參數。)
如果沒有提供initialValue,rece 會從索引1的地方開始執行 callback 方法,
數組去重:
常用對象方法
1、Object.assign()
用於克隆,兩個參數,將第二個對象分配到第一個中
2、Object.is()
用於判斷兩個值是否相同
//注意,該函數與==運算符不同,不會強制轉換任何類型, 應該更加類似於===,但值得注意的是它會將+0和-0視作不同值
3、Object.keys()
用於返回對象可枚舉的屬性和方法的名稱,返回一個屬性或方法名稱的字元串數組。
4、Object.defineProperty()
劫持變數的set和get方法,將屬性添加到對象,或修改現有屬性的特性
5、Object.defineProperties()
可添加多個屬性,與Object.defineProperty()對應,
6、isPrototypeOf
安卓監聽可視區域變化,讓輸入框移動至可視區域
vue中平滑滾動到某個位置
this.$refs.rule.scrollIntoView({ block: 'start', behavior: 'smooth' })
向URL追加參數
解析URL參數
好用的JavaSrcipt庫與模塊(包)
日期時間處理庫
1、monent.js
2、day.js
day相對於monent要輕量許多
高精度數學運算
number-precision
實用工具庫
Lodash
lodash 是一個 JavaScript 實用工具庫,提供一致性,及模塊化、性能和配件等功能。
Lodash 消除了處理數組的麻煩,從而簡化了 JavaScript、 數字、對象、字元串等

四. 語法知識
特殊疑問句通常以「what」、「who」、「which」、「when」、「where」、「how」、「how old」、「how many」等開頭,對某一具體問題進行提問。
特殊疑問句的基本構成有兩種情況:
1. 疑問句+一般疑問句結構。這是最常見的情況。例如:
What』s your grandfather』s telephone number? 你爺爺的電話號碼是多少?
Who is that boy with big eyes? 那個大眼睛的男孩是誰?
Which season do you like best? 你最喜歡哪個季節?
When is he going to play the piano? 他什麼時候彈鋼琴?
Where does he live? 他住在哪兒?
How are you? 你好嗎?
How old are you? 你多大了?
How many brothers and sisters do you have? 你有幾個兄弟姐妹?
2. 疑問句+陳述句結構。這時疑問詞作主語或修飾主語。例如:
Who is on ty today?
今天誰值日?
Which man is your teacher?
哪位男士是你的老師?
我們學過的What/How about+名詞/代詞+其他?也是特殊疑問句,它是一種省略結構。
例如:
I like English. What/How about you? 我喜歡英語。你呢?
What about playing basketball? 打籃球怎麼樣?

J. cvt變速箱和at變速箱哪個可靠耐用
沒有完美的變速箱,cvt和at原則上走了兩條完全不同的路!但是,從可靠性和耐久性的角度來看,at仍然被認為是最好和最穩定的,cvt在特殊速度范圍內具有更好的燃油經濟性。當然,從製造成本來看,cvt遠勝於at,這一點可以從cvt在過分強調成本的日系車中被廣泛使用這一事實中體現出來。
cvt變速箱的原理
從簡單的結構來看,cvt變速箱可以看作液力變矩器+錐輪和鋼帶兩部分,其中液力變矩器主要起到緩沖動力傳遞的作用,而錐輪和鋼帶結構則起到改變傳動比的作用。
液力變矩器是一個空充滿變速箱油的腔體,主要由泵輪、渦輪、導向輪、單向鎖止離合器等組成。其中,泵輪與發動機的輸出軸連接並與發動機同步轉動,渦輪與變速箱的輸入軸連接,導向輪位於泵輪和渦輪之間。發動機的旋轉帶動泵輪高速旋轉,在離心力的作用下,變速箱油攪動渦輪高速旋轉,變速箱油帶動渦輪被動旋轉,實現動力傳遞。導向輪的作用是將變速箱油的旋轉方向導向渦輪葉片,從而增加扭矩。
液力變矩器泵輪與渦輪耦合時,轉速趨於同步。此時單向鎖止離合器被鎖住,發動機和變速箱通過剛性連接直接傳遞動力。此時汽車速度穩定,動力傳遞相對穩定,傳遞損耗最小。
cvt變速箱後段為錐輪鋼帶(鏈)結構。這種結構的原理很簡單。當動力傳遞到cvt變速箱後段,即錐輪和鋼帶(鏈)結構時,液壓系統控制主動錐輪和從動錐輪改變內徑和傳動比。
cvt變速箱的油耗
Cvt變速器利用摩擦傳遞動力,傳動效率相對較低,只有78%左右。由於變矩器啟停時單向鎖止離合器會分離,動力傳遞效率更低。但由於cvt天生沒有物理擋位,在改變傳動比的過程中發動機轉速波動很小,發動機始終可以工作在最佳燃燒效率轉速區間,從而降低了油耗。此外,當cvt改變傳動比時,動力不會一直中斷,這也將降低油耗。當然,cvt只是在一定轉速下相對省油,當cvt變速箱的傳動比達到最高(最大模擬檔位)時,油耗並不低,因為pcm需要控制油壓來保持相對較高的壓力,以保持動力傳動在超高速下不打滑,此時傳動摩擦損失大,油耗高。
cvt的耐用度
很多人對cvt的耐久性持懷疑態度。事實上,沒有證據證明cvt的耐久性差。目前cvt的裝車量已經遠遠超過了1000萬台,在路上跑幾十萬公里的雅閣依然很常見。豐田打算用cvt取代下一代普拉多。你認為這種想法是開放的嗎?在結構上,液力變矩器可以形成一道天然屏障,防止瞬時大扭矩傳遞到變速箱後部。由於液力變矩器最初是由變速箱油傳遞的,發動機的動力只有經過「緩沖」後才能傳遞,因此可以防止瞬間的大扭矩傳遞破壞錐輪與鋼帶之間的「靜摩擦力」,從而避免打滑。但液力變矩器單向鎖止離合器鎖止後,速度穩定。但由於cvt變速箱使用的傳動油會增加摩擦,所以現代cvt整體上不存在所謂的打滑。只要發生打滑,液壓控制肯定有問題。雖然cvt是用摩擦來傳遞動力,但這種摩擦是「靜摩擦」,在耐用性上沒有問題。
日系為什麼青睞cvt?
總的來說還是成本和利潤。cvt結構簡單,只有200個備件,而at隨著檔位的增加需要500多個備件和300個雙離合器。備件數量少,可顯著減少生產工序,降低生產成本,增加利潤。
at變速箱的原理
At變速箱和cvt變速箱有著相似的結構,也就是說,它們都有液力變矩器。在結構上,at變速箱可以分為兩部分:液力變矩器+行星齒輪組,其中液力變矩器在緩沖和傳動方面起到與cvt變速箱相同的作用。
at變速箱後段採用串聯行星齒輪組。通常,隨著齒輪數量的增加,串聯的行星齒輪組的數量也會增加。理論上,一組行星齒輪可以實現兩個速比,兩組可以實現四個速比,三組可以實現八個速比,四組可以實現十六個速比。但是考慮到齒輪速比的有效性,這些速比不能全部有效利用,必須有怠速。變速箱的tcu用不同的電控控制多片離合器的壓緊,控制行星齒輪組的行星架和齒圈的自由度,達到改變傳動比的目的。
在結構上,變速箱中必須有一個固定的物理齒輪。換擋時,發動機轉速會明顯波動。此外,物理檔位還會限制發動機在最佳效率轉速范圍內工作。這時,為了保持發動機的輸出功率,發動機只能通過多次噴油來實現,從而增加了油耗。但是隨著變速箱技術的進步,隨著AT變速箱檔位的增加,檔位之間的速度差會逐漸減小。換擋波動越來越小,越來越接近cvt的無限擋。此外,由於at採用機械齒輪傳動,傳動效率遠高於cvt。因此,目前的8at理論上可以達到與cvt相當的油耗。當然,考慮到價格因素,at變速箱,尤其是高端at變速箱,還是不能完全普及。
at變速箱的耐用度
從結構原理來看,at變速箱前端由液力變矩器保護,後端由機械齒輪傳動,所以理論上磨損很小。因此,相對來說,at變速箱的使用壽命仍然是世界三大自動變速箱中最高的。當然,並不是所有at的故障率和耐用性都很好。因為at變速箱不可避免地使用多離合器來控制行星齒輪組的自由度,如果閥體堵塞,導致液壓系統出現問題,多離合器就會鎖死不良,此時也會出現嚴重的磨損。
