Primary atrial tumor has obvious characteristic on RT-3DE: All the atrial tumor display the same size of stereoimages as the tumor themselves. There is a clear boundary between the stereoimage of the myxoma and the atrial wall and there exists a short pedicle connecting the atrial myxoma to the atrial wall or the interatrial septum. The body of the atrial myxoma moves to and fro through the atrium and the atrioventricular valve with the contraction and relaxation of the heart with a fixative pedicle. Atrial myxoma leads to relative atrioventricular valve incompetence during systolic phase and relative atrioventricular valve stenosis during diastolic phase, but doesn't result in pathological changes of atrioventricular valve which restore to normal after exsection of the atrial myxoma. Malignant atrial tumor closely and extensively contact with atrial wall without obvious boundary, pedicle and movement with the contraction and relaxation of the heart.

所有心房肿瘤RT-3DE均实时显示与肿瘤大小相同的立体形态图像；心房黏液瘤立体形态图像与心房壁界限明显，都通过一短蒂与房间隔或心房壁相连，瘤体以蒂为固定点随心脏收缩、舒张在心房与房室瓣口之间往返运动；心房黏液瘤收缩期瘤体导致房室瓣相对关闭不全，舒张期瘤体导致房室瓣相对狭窄，但瘤体不引起房室瓣器质性病变，瘤体摘除后房室瓣功能即恢复正常；恶性心房肺瘤立体形态图像与心房壁关系密切，界限不明显，接触范围广泛，无蒂，瘤体不随心脏收缩、舒张运动。

Under the scanning electron microscope , for the first time we compare and study both the coalified tracheids through chemical maceration and permineralized tracheid lumen casts. This method reveals the microstructures of wall and perforations of G-type tracheids: 1 The lignified layer of secondary wall is composed of uneven material and further divided into S〓, S〓, S〓 layers; with the smooth enclosing wall, the perforation is internally dumbbell-shaped; 2 In Huia gracilis, the enclosing wall of tracheidal perforation contracts and possesses secondary perforations. The perforation has thickened border facing the tracheid lumen.

The numerical results show that, surface temperature gradient in the pool heated from inner wall is 10% higher than that heated from outer wall with a fixed temperature difference between the outer and inner walls. Meanwhile, the critical Marangoni number for the incipience of hydrothermal wave (Ma_{c}=3.06\times 10^{5}) in the pool heated from inner wall is smaller than that (Ma_{c}=3.34\times 10^{5}) heated from outer wall.

主要内容及结论：1充氡后利用计算机连续进行电离电流累积测量，得到了精细的电流随时间的变化曲线，可清楚看出氡及其子体的生成衰变造成的电离电流的生长—稳定—衰减过程，与理论计算值进行了比较，由电离电流衰减速度的变化得出氡吸附作用的影响，并测量到电离室冲洗后氡的反扩散现象；2由已知活度的标准源定出相对测量的刻度系数K值，K=24.62 Bq／pA，对同一个监测源以半年为周期进行多次测量后得出稳定性符合要求；3通过测量电离电流和气压的关系曲线以及不同气压下的饱和曲线，确定了常规的工作条件；4测量了盐酸清洗电离室内表面降低本底的效果；5不确定度分析表明相对测氡的扩展不确定度(k=2)小于5％，由本底涨落得出探测下限为0.5 Bq；6理论上对壁损失修正进行了计算，实验上保持电离室工作在饱和区的情况下，测量了不同气压下电离电流的变化，从中得出了壁损失随气压变化的规律，可以看出，电离电流的实测值和计算值随气压变化规律基本一致；当气压大于125 kPa时，端效应等其它因素造成的影响不大于2％，因而在此工作条件下，测量电离电流后通过计算修正壁损失可以实现近似的绝对测氡，提出了进一步提高绝对测量准确度的方法。

结果表明，随着煤气热值的增加，导致烟气平均温度的升高，当粗锌熔液流量没有随之升高时，塔盘外壁与内壁温度也随着升高，这造成了烟气向塔盘外壁的传热量有较大的波动，此外，烟气热量均未充分利用，塔盘内壁温度均远高于锌蒸气的沸点，而煤气掺混天然气后，塔盘内壁温度更高，烟气向塔盘外壁的传热量增加比较显著，这是所供粗锌熔液流量太小，使得塔盘内粗锌熔液不能充分带走烟气热量而造成的。
