NTC負溫度系數熱敏電阻歷史NTC熱敏電阻器的發展經歷了漫長的階段.1834年，科學家發現了硫化銀有負溫度系數的特性.193年，科學家發現氧化亞銅-氧化銅也具有負溫度系數的性能，并將之成功地運用在儀器的溫度補償電路中.隨后，由于晶體管技術的不斷發展，熱敏電阻器的研究取得重大進展.196年研制出了NTC熱敏電阻器.NTC負溫度系數熱敏電阻溫度范圍它的測量范圍一般為-1～+3℃，也可做到-2～+1℃，甚至可用于+3～+12℃環境中作測溫用.負溫度系數熱敏電阻器溫度計的精度可以達到.1℃，感溫時間可少至1s以下.它不僅適用于糧倉測溫儀，同時也可應用于食品儲存、醫藥衛生、科學種田、海洋、深井、高空、冰川等方面的溫度測量
一般情況下，塑料擠出機生產產品模溫過低時容易產生應力，應適當提高溫度。但當注射速度較高時，即使模溫低一些，也可減低應力的產生。注射和保壓時間過長也會產生應力，將其適當縮短或進行Th次保壓切換效果較好。非結晶性樹脂，如AS樹脂、ABS樹脂、PMMA樹脂等較結晶性樹脂如聚乙烯、聚甲醛等容易產生殘余應力，應予以注意。脫模推出時，由于脫模斜度小、模具型膠及凸模粗糙，使推出力過大，產生應力，有時甚至在推出桿周圍產生白化或破裂現象。
FBH系列閉式冷卻塔（橫流、復合流）工作原理工作流體（水、油或其他液體）在盤管中流動，盤管外壁被噴淋水包裹，流體的熱量通過管壁傳遞，與水和空氣形成飽和濕熱蒸汽，熱量由風機排入大氣，水分被擋回集水槽循環噴淋，噴淋水在循環的過程中通過PVC散熱片降低水溫，與新鮮入風形成風水同向流動，盤管主要依靠顯熱熱傳導方式，這樣的運行原理的重要特點就是大可能盤管外壁的水垢生成。特別適用于高溫流體（8以上）或冷卻溫差較大（6-35）的流體冷卻。
WA-1B電液式數顯試驗機操作規程在使用前必須進行油、電、機等各項檢查并合格后，按以下步驟操作：使總電源開關接通電源。根據試樣形狀及尺寸把相應的夾頭裝入上、下鉗口座內。開動油泵電機（M1），開啟送油閥，使試驗臺上升5-1mm，然后關閉送油閥，如果試臺已在升起位置時，則不必先開動油泵送油，僅將送油閥關好即可。裝夾試樣。作拉伸試驗時，先啟動油泵，再打開送油閥，使工作活塞升起一段后關閉送油閥，分別操作上、下鉗口夾緊、松開裝置，將一端夾于上鉗口，再調整下鉗口，開動下鉗口（移動橫梁）電動機（M2），將下鉗口升降到適合高度，將試樣另一端夾在下鉗口中，必須注意使試樣鉛垂，并夾在夾頭的全長上，對準中間位置。
