Like any other Gramineous crop, hybrid rice keeps 80% of totally removed K in its shoots after ripening, only about 20% of K uptake is transported to grain, grain K content was more stable, usually around 0.5%.

同其它禾本科作物一样，成熟后杂交水稻保存总移出钾的80%在其茎杆中，只有20%吸收的钾转移到籽粒中，籽粒含钾量更为稳定，一般约为0.5%（表6）。

In this paper, the baroclinic pole in baroclinic theory is supposed to be membrane-element subjected to shearing stress and normal stress in plain section. With the help of truss model, it meets the equation of two-dimension stress, Moire's strain corresponding equation and double-axis intenerate strain-stress relationship of concrete. It describes the load-behavior and working property of reinforced concrete combined torsion members in the whole load-deformation process.

本文将斜压场理论中的斜压杆表达成在平面内承受剪应力和正应力的钢筋混凝土薄膜元，借助桁架模型，满足二维应力平衡条件、莫尔应变协调条件和混凝土的双轴软化本构关系，揭示钢筋混凝土复合受力构件在受力-变形全过程中受力行为和工作性能，为研究复合受扭构件的变形行为打下了坚实的基础。

One would approach at first warily through the shrub oaks, running over the snow-crust by fits and starts like a leaf blown by the wind, now a few paces this way, with wonderful speed and waste of energy, making inconceivable haste with his "trotters," as if it were for a wager,and now as many paces that way, but never getting on more than half a rod at a time; and then suddenly pausing with a ludicrous expression and a gratuitous somerset, as if all the eyes in the universe were eyed on him —— for all the motions of a squirrel, even in the most solitary recesses of the forest, imply spectators as much as those of a dancing girl —— wasting more time in delay and circumspection than would have sufficed to walk the whole distance—— I never saw one walk —— and then suddenly, before you could say Jack Robinson, he would be in the top of a young pitch pine, winding up his clock and chiding all imaginary spectators, soliloquizing and talking to all the universe at the same time —— for no reason that I could ever detect, or he himself was aware of, I suspect.

有一只赤松鼠开始谨慎地穿过矮橡树丛，跑跑停停地在雪地奔驰，像一张叶子给风的溜溜地吹了过来；一忽儿它向这个方向跑了几步，速度惊人，精力也消耗得过了份，它用&跑步&的姿态急跑，快得不可想象，似乎它是来作孤注一掷的，一忽儿它向那个方向也跑那么几步，但每一次总不超出半杆之遥；于是突然间做了一个滑稽的表情停了步，无缘无故地翻一个觔斗，仿佛全宇宙的眼睛都在看着它，——因为一只松鼠的行动，即使在森林最深最寂寞的地方，也好像舞女一样，似乎总是有观众在场的，——它在拖宕，兜圈子中，浪费了更多的时间，如果直线进行，早毕全程，——我却从没有看见过一只松鼠能泰然步行过，——然后，突然，刹那之间，它已经在一个小苍松的顶上，开足了它的发条，责骂一切假想中的观众，又像是在独白，同时又像是在向全宇宙说话，一我丝毫猜不出这是什么理由，我想，它自己也未必说得出理由来。

This paper introduces four kinds of method for increasing devolatilizing efficiency in cold feeding vented extruder s These methods are:(1)reducing the filled degree of rubber compounds in the vented section of screw;(2)increasing the mean residence time in the vented zone;(3)enhancing the effect of renewing the evaporating surface;and (4)improving the ingredients and operating variable

介绍了 4种提高橡胶冷喂料排气挤出机除气效率的途径：减少胶料在螺杆排气段中的进料度，增加胶料在排气段中的平均停留时间，增强胶料&自由&表面积的更新作用，改进配方设计和操作工艺条件等。

Results①The tunica intima and tunica media of the BVs were thin, the tunica adventitia was thick. No complete layer of smooth muscle was found in the tunica intima, the SMC with single elliptical or rod-shape nuclear, fusiform in shape and different in length, ran longitudinally and distributed unequally in the wall of BVs, intercrossed with each other, endothenial cell wasn't covered fully sometimes.

中膜未见完整平滑肌层，SMC呈梭形，大多呈纵切面，有的呈斜切面，不均匀地分布于管壁中；平滑肌纤维长短不一，相互交错排列，有时并不完全覆盖内皮细胞，细胞核单个，椭圆形或长杆状。

Polymer properties, morphology,processing condition, and processing equipment are the key links which interplayed in polymer extruding process.

单螺杆挤出过程中聚合物的形态结构、加工工艺、加工设备和制品性能是聚合物挤出加工过程中相互影响、密切联系的四个重要环节。

Finally, through the instance of engineering, we can see that the steel dosage in steel honeycomb plank is smaller and the self-weight of the whole structure is lighter comparing with pyramided grid structure, and the steel dosage in portal strut with honeycomb laminated beam-column system is still smaller and the self-weight is still smaller comparing with steel I-beam,they will have a wide applied foreground.

最后，通过工程实例分析表明，在大跨度屋盖结构中，金属蜂窝板-杆空间结构体系比常规的四角锥网架结构具有用钢量低，结构整体自重轻等优点；在轻钢结构厂房中，采用金属蜂窝纯板片箱梁体系比一般H型钢结构用钢量更低，自重更轻，具有广泛的应用前景。
