The average ADC was lower in the primarily focus of nasopharyngeal non cornification anaplastic carcinoma and metastatic lymph nodes than normal control group.

结果 鼻咽非角化型未分化癌不同中医证型的平均ADC值的差异有显著统计学意义(x2=15.987,P=0.000),火毒困结型的平均ADC值明显高于痰浊结聚型、气血凝结型,且差异有显著统计学意义(P<0.01);鼻咽非角化型未分化癌原发灶及其转移性颈部、咽后淋巴结的平均ADC值均低于对照组,且差异有显著统计学意义(P<0.01)。

So the proposed method in this dissertation not only meet the requirements for fossil-fuel unit set in GB/T 12145-1999, but also can effectively restrain condensate and feed water system corrosion. Thereby the proposed method can reduce the loss by corrosion's leading accident, lower Fe content in boiler feed water, slow the boiler's scaling speed, delay boiler's chemical cleaning interval, effectively enhance unit's reliability, usability and using life and solve the problem of poisonous chemical deoxidant. So the proposed method can economize substantial expense for power plant.

所以,本文所提出的汽包炉有限氧化性水化学工况不但能满足GB/T12145-1999中对火力发电机组及蒸汽动力设备的要求,而且可有效抑制凝结水和给水系统的腐蚀,减少因这些部位腐蚀损坏而引发的事故停机损失,降低锅炉给水中的金属含量,减轻炉内的结垢速度,延长锅炉的酸洗间隔,有效提高机组的可靠性、可用率和使用寿命,同时也解决了有毒化学除氧剂的使用问题,为电厂节省大笔运行费用。

模拟的 运动场和云微物理量场的时空演变表明,垂直运动场与水汽场的耦合是水汽凝结和冻结成雪的运动学条件;气旋性涡柱和上升运动及深厚湿舌的耦合是暴雪形成的一种重要动力机制。

The development of saprolite is realized by the progressive propagation of the weathering front of low permeable rock blocks, and the condensate from the moisture and the unsaturated seepage flow are the key agents of the propagation process.

腐岩发育是通过低渗透岩石结构体风化前锋的渐进性扩展实现的,非饱和带高湿度空气形成的凝结水和降水入渗形成的非饱和渗流是该过程的核心动力。

The results show that REEs oxide have little effect on the decomposition of carbonate and they improve the sinterability of the raw meal;they also promote the formation of alite and growth of clinker minerals,and have beneficial effect on the uniformity of crystal size and well-distributed minerals. But some REEs result in the corrosion of alite when they are excessive,which may influence the hydration reactivity of alite.When clinker is well sintered, REEs oxide and its tailing improve the strength of cement clinker, and have little effect on setting time of cement.

研究结果表明,稀土氧化物对碳酸盐的分解影响不大,对生料的易烧性有改善作用;稀土氧化物能促进熟料中A矿的形成和矿物的发育,有利于熟料中矿物结晶尺寸和分布均匀,但部分稀土在掺量过量时可能造成矿物的熔蚀,影响矿物的水化活性;在煅烧良好的条件下,稀土氧化物和尾矿对熟料强度有增进作用,对水泥凝结时间影响较小。

Study of the causes of MCS intensification and rainstorm shows that( 1) just before the heavy rains occur, there are high temperature, considerably wetness and unsteady convective stratification in the air over the rainstorm-hit area, in addition to significant increase in convectively efficient potential energy, condensation height and decrease in the height of free convection – all these favor the happening of the heavy rain,(2) the mergence of meso-βcloud clusters leads to the MCS such fast growth as to produce rainstorm,( 3) the two lines of cumuli in the north and west correspond, separately, to two convergences on the surface wind field, with stronger convergence at their meeting point responsible for such intense development of meso-βcloud cluster as to bring about torrential rains.

分析MCS加强和产生暴雨的原因表明,首先,暴雨发生前夕暴雨区域具有高温、高湿和对流性不稳定层结,并存在明显的对流有效位能增加、抬升凝结高度及自由对流高度降低的现象,有利于暴雨发生。第二,β中尺度云团之间的合并,使MCS迅速增长,产生暴雨。第三,北、西两条积云线分别与地面风场中的两条辐合线相对应,在它们交汇处的较强辐合导致β中尺度云团强烈发展产生暴雨。
