降温速度 meaning in Chinese
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
