In order to reduce the erosion of water-wall,large furnace sectional area should be selected by boiler works,and the power plant should select the coal caloricity close to the designed for use.

对于循环流化床锅炉，炉膛截面积选择的大小影响炉内循环物料的速度，即水冷壁的磨损速度，燃料的发热量影响炉内循环物料的浓度。

The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.

利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

The results showed that people who drank black tea arterial wall contractility markedly improved, but adding milk a group of people is very clear that the impact of.

结果显示，喝红茶的人的动脉血管壁的收缩能力有了明显提高，但加入牛奶的一组人的这一影响很不明显。

The fabrication processes for nano-silicon-tips using a (100) single crystal silicon wafer by the anisotropic wet etching in the KOH etchant were designed. Based on the experiment and the model of {411} crystal planes, the crystal planes of silicon tips were analyzed. Through discussing the effect of the mask direction on tip shapes, the process parameters to get high aspect ratio nano-silicon-tips were achieved.

设计了硅尖制备的工艺流程，采用KOH溶液湿法各向异性腐蚀(100)单晶硅的方法制备硅尖，根据实验结果和{411}晶面模型，分析了硅尖侧壁的组成晶面，讨论了掩模偏转方向对硅尖形状的影响，得到了制备高纵横比纳米硅尖的工艺参数。

Little mouse is put into a box in the wall somewhere in the box has a button, the button is connected to a supply of food equipment, rattling around a small mouse in the case of an accidental hit the button, so the box out out of food, access to food many times, the little mouse seems to love the button, click the icon it is always time to time, even if not hungry.

二 小老鼠被装进一只箱子中，在箱壁的某处有一个按钮，按钮连接着某个供给食物的装置，到处乱撞的小老鼠在一次偶然的情况下碰到了按钮，于是箱子里掉出了食物，多次获得食物后，小老鼠似乎爱上了这个按钮，总要时不时地按一按它，即使并不饥饿。

On the basis of structural features and heat transfer characteristics of a spiral-grooved tube heat exchanger,a three-dimensional geometric model was established for the flow and heat transfer in a heat exchanger with water serving as its working medium.

根据螺旋槽管换热器结构特点及传热特性，建立了以水为工质的换热器流动与传热的三维几何模型。运用有限元分析软件ANSYS模拟出换热器在换热过程中速度场与温度场的状况，分别得到了螺旋槽管内壁与外壁的对流换热系数。

In order to be fit for the calculation of wave transformation in harbor basin with irregular solid boundary, the governing equations and the boundary conditions of the present model are transformed by a non--orthogonal coordinate. Comparisons with the theoretical solutions indicate that the transformation is correct.
