Bonny說(shuō):“我非常了解熱成像。
作為滅蜂人的經(jīng)驗告訴我,拆除蜂窩時(shí),我們感覺(jué)到蜂窩里散發(fā)出一定的熱量。
于是,我想如果這些馬蜂窩是暖和的,那就一定能用熱成像儀發(fā)現它們。
”傳統方法耗時(shí)耗力昆蟲(chóng)是冷血動(dòng)物的,但它們確實(shí)會(huì )產(chǎn)生熱量。
作為具有社會(huì )性特征的昆蟲(chóng),它們常常會(huì )聚集在一起,將它們的熱量結合起來(lái),使發(fā)育中的幼蟲(chóng)保持溫暖。
通過(guò)熱像儀可以清楚地看到這種熱現象,業(yè)人員可以找到屋頂區域、拱腹或墻洞里的蜂窩。
RaytekMMMT測溫儀巧妙避免火焰測溫過(guò)程中可能會(huì )產(chǎn)生的測量偏差,限度節省成本并提高生產(chǎn)效率。
(屬退火與淬火應用)結構鋼和屬形狀被制造出來(lái)以后,屬的特定部分需要進(jìn)行退火或回火處理。
,工字鋼的兩端必須經(jīng)過(guò)退火處理以防止在施工現場(chǎng)一個(gè)工字鋼與另一個(gè)連接時(shí)發(fā)生損壞。
另一個(gè)例子是摩托車(chē)的啟動(dòng)踏板,啟動(dòng)踏板的中心位置需要經(jīng)過(guò)回火處理,以承受當有人試圖啟動(dòng)摩托車(chē)時(shí)產(chǎn)生的過(guò)矩。
