4極永磁無刷直流電機仿真結(jié)果英文翻譯word資料8頁(共8頁)

1、4極永磁無刷直流電機仿真結(jié)果課本、報刊雜志中的成語、名言警句等俯首皆是,但學生寫作文運用到文章中的甚少,即使運用也很難做到恰如其分。為什么?還是沒有徹底“記死”的緣故。要解決這個問題,方法很簡單,每天花3-5分鐘左右的時間記一條成語、一則名言警句即可。可以寫在后黑板的“積累專欄”上每日一換,可以在每天課前的3分鐘讓學生輪流講解,也可讓學生個人搜集,每天往筆記本上抄寫,教師定期檢查等等。這樣,一年就可記300多條成語、300多則名言警句,日積月累,終究會成為一筆不小的財富。這些成語典故“貯藏”在學生腦中,自然會出口成章,寫作時便會隨心所欲地“提取”出來,使文章增色添輝。 BRUSHLESS PE

2、RMANENT MAGNET DC MOTOR DESIGN觀察內(nèi)容的選擇，我本著先靜后動，由近及遠的原則，有目的、有計劃的先安排與幼兒生活接近的，能理解的觀察內(nèi)容。隨機觀察也是不可少的，是相當有趣的，如蜻蜓、蚯蚓、毛毛蟲等，孩子一邊觀察，一邊提問，興趣很濃。我提供的觀察對象，注意形象逼真，色彩鮮明，大小適中，引導幼兒多角度多層面地進行觀察，保證每個幼兒看得到，看得清。看得清才能說得正確。在觀察過程中指導。我注意幫助幼兒學習正確的觀察方法，即按順序觀察和抓住事物的不同特征重點觀察，觀察與說話相結(jié)合，在觀察中積累詞匯，理解詞匯，如一次我抓住時機，引導幼兒觀察雷雨，雷雨前天空急劇變化，烏云密布，我

3、問幼兒烏云是什么樣子的，有的孩子說：烏云像大海的波浪。有的孩子說“烏云跑得飛快。”我加以肯定說“這是烏云滾滾?！碑斢變嚎吹介W電時，我告訴他“這叫電光閃閃?！苯又變郝牭嚼茁曮@叫起來，我抓住時機說：“這就是雷聲隆隆?！币粫合缕鹆舜笥?，我問：“雨下得怎樣?”幼兒說大極了，我就舀一盆水往下一倒，作比較觀察，讓幼兒掌握“傾盆大雨”這個詞。雨后，我又帶幼兒觀察晴朗的天空，朗誦自編的一首兒歌：“藍天高，白云飄，鳥兒飛，樹兒搖，太陽公公咪咪笑。”這樣抓住特征見景生情，幼兒不僅印象深刻，對雷雨前后氣象變化的詞語學得快，記得牢，而且會應(yīng)用。我還在觀察的基礎(chǔ)上，引導幼兒聯(lián)想，讓他們與以往學的詞語、生活經(jīng)驗聯(lián)系起

4、來，在發(fā)展想象力中發(fā)展語言。如啄木鳥的嘴是長長的，尖尖的，硬硬的，像醫(yī)生用的手術(shù)刀樣，給大樹開刀治病。通過聯(lián)想，幼兒能夠生動形象地描述觀察對象。 File: Setup1.res死記硬背是一種傳統(tǒng)的教學方式,在我國有悠久的歷史。但隨著素質(zhì)教育的開展,死記硬背被作為一種僵化的、阻礙學生能力發(fā)展的教學方式,漸漸為人們所摒棄;而另一方面,老師們又為提高學生的語文素養(yǎng)煞費苦心。其實,只要應(yīng)用得當,“死記硬背”與提高學生素質(zhì)并不矛盾。相反,它恰是提高學生語文水平的重要前提和基礎(chǔ)。 GENERAL DATARated Output Power (kW):0.55 額定輸出功率Rated Voltage (
