Based on our experiences, we conclude that: 1 rhabdomyoma is the most common primary cardiac tumor in children; 2 most pediatric tumors are associated with tuberous sclerosis; 3 clinical presentation is determined by the tumor size and number of tumors, and whether expansion of the malignancy has resulted in cardiac blood-flow obstruction; 4 there is a strong possibility of regression of the primary cardiac tumor, with surgery recommended only when cardiac symptoms are severe; and, 5 unless there is a significant obstruction of blood flow, chemotherapy is still the treatment of choice for secondary cardiac tumors.

根据我们的经验，我们认为(1)横纹肌瘤是儿童最常见的心臓肿瘤，(2)临床表现的严重度取决於肿瘤的大小，数目以及是否占满了心臓腔室而有血流阻塞的现象，(4)在原发性肿瘤中是有机会自发性的变小，而且除非有严重的心臓症状，否则并不建议开刀，(5)在次发性肿瘤中化学治疗仍然是治疗上的首选，除非有血流阻塞的现象。

Based on the rigorous analysis of the kinetic process of both primary and secondary electrons, the related surface charges were analyzed, and the energy gain of emitted electrons was proportional to the square of the ratio between the tangential and normal component of electric field. In this process, the image force of mirror charges would result in an energy loss. Meanwhile, the effect of field alternation of power frequency ac voltage on electron movement could be ignored.

在前人工作的基础上，进一步严格推导了场致一次发射电子和二次电子的运动方程，分析了电子发射引起的绝缘材料表面带电，表明电子发射后的能量增益正比于场强的切向与法向分量比值 F /// F ^的二次方；同时考虑了在电子发射和运动过程中电荷镜像力的作用，并探讨了交流电压下表面带电的情形，认为当考虑电荷镜像力的作用时，电子的能量增益可能变小，而工频交流电压下电场交变对电子运动的影响可以忽略。

Studied the solid particles cyclone separation under structural parameters and operating parameters of different hydrocyclone, the results showed that major factor influence split ratio is in the ratio of entrance to exit pressure of hydrocyclone. Exit pressure has a certain influence on the split ratio, the various of the diameter and cone angle of hydrocyclone (in the ratio of entrance to exit pressure is constant) have no influence on split ratio; With diameter and cone angle increase, the separation granularity gradually increasing and recovery ratio decreasing; With entrance pressure increase, the separation granularity of hydrocyclone decrease, the split ratio of underset will increase slowly; With the diameter of overflow pipe increase, the separation granularity of hydrocyclone increasing and recovery ratio decreasing; With the diameter of underset pipe increasing, the separation granularity of hydrocyclone decreasing and recovery ratio increasing.

在不同的水力旋流器结构参数和操作参数下，对固体颗粒的旋流分离进行了分析研究，结果表明：旋流器的排出口比是影响分流比的主要因素，进口压力对分流比有一定影响，水力旋流器的直径变化和锥段角度变化对分流比基本上没有影响；随着直径、锥段角度的增大，分离粒度逐渐增大，回收率降低；随着入口压力增大，水力旋流器的分离粒度变小，底流的分流比会缓慢增加；随着溢流管管径的增加，分离粒度增大，分流比明显减小，回收率降低；随着底流管直径的增加，分离粒度减小，分级效果明显下降，回收率会增加。

In a transportation network supported by the Advanced Traveler Information Systems,the drivers equipped with ATIS are directed by a control center to select their routes so as to minimize the total network travel time,while the unequipped ones make the route choice decisions on the base of minimizing their individual travel times.

考虑一个被路径诱导系统支持的交通网络，装有ATIS的出行者接受交通中心的指挥、按照系统最优的原则选择路径，没有该装置的出行者根据个人成本最小的原则择路，建立了刻画这种混合交通行为的变分不等式模型，推导了混合交通行为网络的效率损失上界，并以多项式路段成本函数为例给出了一些上界的特殊值。

From the tests,we have obtained some structural variant features related with salt resistance and demonstrated the successful introduction of Rhizophora apicularta DNA into tomato.This thesis contains two parts. In the first part,the morphological and anatomical structures of the leaves were investigated. As to the morphology,some difference between control and transformed tomato were found. The leaf dimensions of the transformed tomato with unextended leaves were smaller than that of control. These structure changes should help to decrease the evaporation of water effectively and release the physiological drought resulted from saline.

本实验分两部分：第一部分、对转化番茄的形态及细胞显微结构进行观察与分析，实验表明转化番茄形态与对照相比有明显的变化，其叶面积变小，叶形收拢，这种结构可有效地减少水分的蒸发，缓解由盐胁产生的生理干旱；组织解剖结构结果显示，耐盐番茄在细胞结构上发生了明显的变异：其气孔器倾向下陷，表皮毛增多，叶脉微管组织不发达，微管束周围出现增多的贮水细胞，叶缘及其它部位表面分化出大型的多细胞分泌型结构，这些结构与转化番茄后代较强的耐盐能力有关。

Experiment shows that both the dry plate pressure drop and the wet plate pressure drop increase with the increase of the kinetic energy factor in plate hole but have no influence of the height of cap. The wet plate pressure drop linearly ascends as the clear liquid height increases. Liquid lift-up increases at first then decreases with the increasing of the kinetic energy factor in plate hole, increases with the clear liquid height increasing and the height of cap decreasing, but as the kinetic energy factor in plate hole increased, the influence of height of cap will gradually decreased.

实验表明干板压降、湿板压降均随板孔动能因子的增大而增大，不受罩体高度变化的影响，湿板压降随清液层高度的增大而增大，成正比关系；液体提升量随板孔动能因子的增大先增大后减小，随清液层高度的增大而增大，随罩体高度的增大而减小，但随板孔动能因子的增加，罩体高度的影响逐渐变小；漏液量随板孔动能因子的增大迅速减小，随清液层高度的增大而增大，但接近漏液点时清液层高度的影响不明显。

Factual Baidu also is being done so, you analyse Baidu to be done so is well-founded, one can go up the website of independent server, the machine that is rubbish station leads decrescent, the resource of independent server is OK to the top of one's bent let Baidu spider to the top of one's bent it is above the website creeping, baidu spider crawls here for certain all the more comfortable, comfortable place lets Baidu spider not only not be willing to part with or use goes, and often still want to come.

事实百度也是在这样做的，你分析一下百度这样做是有理由的，一个可以上独立服务器的网站，是垃圾站的机率变小，独立服务器的资源可以尽情的让百度蜘蛛尽情的在网站上面爬行，百度蜘蛛肯定在这里爬行的格外的舒服，舒服的地方不仅让百度蜘蛛不舍得走，而且还常想来。

The morphologic change of muscle fibers: At the early stage of denervation, the area of cross sections decreased, some muscle fibers turned into angular fibers, nuclei congregated around the center of the fibers. After 8 weeks of denervation, atrophic and hypertrophic fibers coexist. Collagen increases under the endomysium and between the fibers.

The capacity of single pile will enhance when the length and diameter of pile increases, but effect of pile diameter is more obvious. While pile diameter increases 20、40 and 60 percents, the capacity of pile will enhance 20.4、53.7 and 78.1 percents. And with the effect of mud-cake, the capacity of single bored pile will fall down nearly 20 percents, and pile-side resistance will also reduce 15 — 35 percents. In the centrifuge tests, when the relative displacement between pile and soil was 45 —85mm, which is much more than the criterions, the pile-side resistance will become most. Meanwhile the intenerated value of utmost resistance is close to the resistance in situ. In the pile group tests, the capacity of pile group , which the space among piles increases from 2D to 3D、 4D and 5D , will enhance 6.1、9.6、18 percents .
