pull stretch 中文意思是什麼
pull stretch
解釋
扳伸-
The machine is applicable to the plasticity material to inhibit the craft, such as hurtles to press, curve, turn over the side, lamella to pull to stretch etc. craft, also can used for correct, pressing to pack, the emery wheel model, the cold crowded metals spare parts model, the plastics product and the powder product of inhibit and model craft
本機器適用於可塑性材料的壓制工藝，如沖壓、彎曲、翻邊、薄板拉伸等工藝，也可用於校正、壓裝、砂輪成型，冷擠金屬零件成型、塑料製品及粉末製品的壓製成型工藝。 -
For rotor steel ( 30crlmolv steel ), the tests of low - cycle fatigue property are done under different temperatures. the fatigue life under different temperatures is researched to make up for the defects of the testing for foreign similar materials. when pull - stretch data is attempted to evaluate low - cycle fatigue data, the result shows that four - point associated method in middle - low life zone is done well under room temperature, but there are large errors of four - point associated method and general - slope method under other temperatures
在本文中，通過與國外同類材料的性能進行比較，國產材料與國外材料共有的材料特徵基本相同；對轉子鋼（ 30crlmolv鋼）進行了不同溫度下的低周疲勞性能實驗，研究其在不同溫度下疲勞壽命，以彌補國外對同類鋼材測試的不足；採用拉伸數據預測低周疲勞壽命時發現，室溫條件下用四點關聯法在中低壽命區預測較好，在高溫條件下四點關聯法和通用斜率法都有較大誤差，需要進行改進。 -
But because of concrete ability of anti - pull to stretch very weak, a mass concrete const ruction cause cracking will be unavoidable
另外，由於混凝土的抗拉伸能力很弱，所以，大體積混凝土結構出現開裂就很難避免。 -
At present experiment on the test the pull and press intensity test to rubber is usually curried out on the stretch experiment machine. most of the testing systems for homemade stretch experiment machines are based on single chip and others are based on pc systems
目前對橡膠產品進行拉壓強度檢測實驗一般是在拉伸試驗機上進行，國產拉伸試驗機大部分是以單片機為主的測試系統，也有部分拉伸試驗機是以pc機系統為核心的測試系統。 -
Therefore, increase concrete anti - pull to stretch ability and reduce concrete control is very necessary. base on above reason, for research of measure of anti - crack of mass concrete in not carry have very of important meaning
為了提高混凝土的抗拉伸能力和減少混凝土的內、外部約束，研究大體積混凝土在非荷載應力作用下的施工系統控制具有十分的重要意義。
