Deformation greatly promoted carbonitride isothermal precipitation and made C-curve shift leftwards. The position and shape of C-curve depended on the content of Nb and N to a great extent, C-curve shifted leftwards a little when N content increased and its nose temperature was raised with Nb content increased. 3 when cooling rate increased, start temperature and finish temperature of continuous cooling precipitation decreased, full precipitation became difficult to take place, the volume fraction of carbonitride precipitation decreased, molar fraction of Nb and C dissolved in austenite increased, and the precipitation grain was further refined. Deformation shorten precipitation start time during continuous cooling, raised precipitation start temperature, accelerated precipitation kinetics of carbonitrides.

计算表明：1在Fe—Nb—C系统中，随着温度的降低，析出相的平衡体积分数增加，溶解在奥氏体中的Nb、C的摩尔分数降低，析出相中C和Nb的原子分数的比值v增加；2变形大大促进了碳氮化物的等温析出，使C曲线左移，Nb和N的含量与C曲线的位置和形状有一定的关系，N含量的增加，使C曲线略有左移，而Nb的含量的增加使得C曲线的鼻子区上移；3随着冷却速率的增大，连续冷却析出的开始温度和结束温度均有所降低，并且析出变得越来越不充分，析出相体积分数明显减小，溶解在奥氏体中Nb和C的摩尔分数增大，析出相粒子被明显细化，变形大大缩短了CCP过程碳氮化物析出的开始时间，提高了析出的开始温度，促进了析出动力学。

Precipitation analysis sub-system . Precipitation is the ultimate origin of water resource. According to the statistics of precipitation material in the past 50years, the spatial database of precipitation was founded, it included the location of precipitation observation stations, mensal precipitation, and so on.

1降水分析子系统降水是水资源最根本的来源，根据过去50年降水观测资料，建立降水量空间数据库，包括雨量观测站位置、按月统计的降水量等。

The outcomes show that a the correlation between ELNINO and precipitation of Shandong is remarkable and the influence of ELNINO or La Nina to the amount of precipitation of coastland in Shandong is much greater than that of the inland. Shandong precipitation is in a trend of reduction during the happening year of ELNINO and the precipitation is in a trend of increase during the happening year of La Nina; b whether is ELNINO or La Nina, the influence to the precipitation of Shandong is mainly concentrated in summer and autumn, almost no influence in spring and the influence to precipitation trend in winter and whole year is just contrary and; c the dry year of Shandong Province mainly happens in the continuous ELNINO years or the next year of La Nina and floods basically happens in La Nina year or the next year of La Nina.

结果表明：①厄尔尼诺与山东省降水相关性显著，无论是厄尔尼诺还是拉尼娜，它们对山东省沿海降水量的影响远大于对内陆的影响，厄尔尼诺发生的年份，山东省降水量呈减小趋势，而拉尼娜发生的年份，降水量呈增大趋势；②无论是厄尔尼诺还是拉尼娜，对山东省降水量的影响主要集中在夏季和秋季，对春季几乎没有什么影响，对冬季降水趋势的影响与全年的影响正好相反；③山东省的干旱年份主要发生在连续性厄尔尼诺年或者厄尔尼诺的次年，而洪涝基本发生在拉尼娜年或拉尼娜的次年。

precipitation：析出

"973"的工作发展了位错驰豫(Relaxation)--析出(Precipitation)--控制(Controlling)技术,即RPC技术. 它是将热轧后具有高密度位错的组织状态,经过轧后在高温阶段适当时间保持,让高密度位错在无外力条件下适当驰豫,

precipitation：沉淀

凝集(coagulation)和沉淀(precipitation):原水也含悬浮物质(如油),必须将之去除(至1ppm以下)以防止起泡及锅炉沉积. 极小的颗粒不会沉降下来,且会穿透过滤器. 要除去这些微细颗粒(通常为胶体(colloidal)物质)须用凝集剂.

precipitation：沉淀反应

沉淀反应 (precipitation)一种血清学反应. 可溶性抗原与相应抗体结合,在有适量电介质存在下,经过一定时间,形成肉眼可见的沉淀物. 沉淀反应的抗原可以是多糖、蛋白质、类脂等. 同相应抗体比较,抗原的分子小,单位体积内含有的抗原量多,

precipitation：降水

一种相似的对于高贵的渴慕,使得"下雨"(rain)成了"降水"(precipitation),在戏剧界里"舞蹈"成了"移动"(movement),而在商界里"损失"(loss)成了"缺失"(shortfall).

precipitation hardening：析出硬化

precipitation 析出 | precipitation hardening 析出硬化 | press quenching 加压硬化
