降温速度 meaning in English
cooling rate
Examples
- The cooling in gradient method was applied , the uneven cooling speed was avoided
通过工艺改进，采用自上而下的梯度式降温方式，避免了降温速度不均匀的问题。 - Under the condition that the variance of temperature in the furnace was lower than 2 . 5oc , the accuracy of temperature control was higher than 0 . 2oc and the speed of temperature drop was 0 . 2oc ~ 2oc , we grew doped - ktp crystals without obvious defects by immerged - seeded solution method
在晶体生长炉温场均匀性高于2 . 5oc 、控温精度高于0 . 2oc 、降温速度为0 . 2oc ~ 2oc的条件下，采用浸没籽晶缓慢降温法生长出宏观无明显缺陷的掺质ktp晶体。 - Pulse electric current heat treatment ( pecht ) developed by sodick , ltd . , of japan , is a recently developed material processing method which consists of spark plasma sintering and welding , plasma activated sintering and welding , big pulse electric current ( bpec ) diffusion welding etc . the following are basic merits of pecht : rapid heating and cooling ; short sintering or welding time ; lowering sintering or welding temperature
脉冲电流热加工( pulseelectriccurrentheattreatment ，比如烧结，焊接等)是九十年代发展起来的一种材料快速制备新技术，它包括放电等离子烧结与焊接、等离子活化烧结与焊接、脉冲大电流扩散焊接等。它具有升温、降温速度快、能在较低的温度下烧结或焊接以及时间短的特点。 - Then , the effect of heavily doped boron on ig of czochralski silicon was also investigated . it is found that no dz ( denuded zones ) were observed in the hb samples subjected to high one - step temperature , ramping annealing respectively . for conventional high - low - high three - step ig annealing , the dz becomes narrower and bmd density is higher in hb samples than that in lb samples , as a result of hb enhancing oxygen precipitation
结果显示，单步高温热处理时重掺硼样品不能形成洁净区；降温退火中，降温速度较为缓慢( 3 / min )时能生成一定量的氧沉淀，但没有洁净区形成；普通高?低?高三步热处理过程中，形成明显的洁净区，但相对轻掺样品而言，洁净区较窄，氧沉淀密度明显偏高，说明重掺硼样品吸杂能力强。 - The process of growing ktp crystal of high quality and low conductivity was studied . it was pointed out that many factors such as the uniformity of temperature distribution in the furnace , the accuracy of temperature control , the quality and direction of seed crystal and the speed of temperature drop all had an important influence on the quality of ktp crystal
研究了生长高光学质量、低电导率ktp晶体的工艺过程，指出晶体生长炉温度场的均匀性、控温精度、籽晶的质量和定向以及降温速度的快慢对晶体的光学质量有着重要的影响。
