Compared with plant density of 150×10^4 planta/hm^2, photosynthesis attenuation rate of traditional plant density of 450×10^4 plants/hm^2 increased by 25.2~43.5 percent point, photosynthesis yield and relative electron transport rate of them decreased 2.95%~20.68% and 10.66%~18.32%, respectively, and the proportion of the reception of photosynthesis active radiation increased upper the layer of flag leaf, and decreased the proportion received lower the layer of flag leaf.

播量为450万株／hm^2处理比150万株／hm^2处理旗叶的光合衰减率提高25.2~43.5个百分点，光合量子产量和相对电子传递速率分别降低2.95%~20.68%和10.66%~18.32%，群体上层的光截获量增加，中下部受光条件较差。

Spikelets plumply elliptic, 1.5–1.7(–2.2) mm, pale or purple tinged; flo-rets similar; glumes equal to spikelet, 5–7-veined, glabrous or sparsely setose, with broad incurving margins, subacute, lower glume elliptic, upper glume broader; lemmas smooth, glabrous or puberulous above the middle, minutely ciliolate along upper margins.

微染的小穗plumply椭圆形，1.5-1.7(-2.2)毫米，浅的或紫色； flo 渍于水中相似；等于的颖片小穗，5-7－脉，无毛的或稀疏刚毛，具宽incurving边缘，近尖，下部椭圆形，宽的上面颖片；外稃平滑，无毛或高于上面边缘的具短缘毛的那些中间，微小的。

So the polydisperse coefficient changes with depth.

总的来说，在水体上部多分散系数偏大，水体下部偏小。

Because the rotational characteristic of the device has a certain property of time varying and non-stationary, there is still no satisfactory development that can solve some complicated and polygenetic faults diagnosis produced in the practice.

回转支承装置是许多大型工程设备的关键部件，是正在发展使用中的一种新的结构形式，它联结了设备上部旋转结构和下部固定结构，因此，它的工作状态常常制约了整机的工作状态，对它的故障诊断具有重要的实践意义。

Results Cerebellopontine angale region the lower neurovascular complex included glossopharyngeal nerve, vagus nerves, accessory nerve and hypoglossal nerves, and interrelated to posteroinferior cerebellar artery, bulbus medulla, cerebellar peduncle, bulbus fissurae cerebelli and cerebello-napex.

结果 桥小脑角区下血管神经复合体主要包括舌咽神经、迷走神经、副神经及舌下神经和相关的小脑后下动脉及延髓、小脑下脚、延髓小脑沟及小脑枕下部等。

The cells of proembryo had strong division ability, and there were distinct difference in shape and obvious boundary between them/it and the surrounding tissues.

原胚细胞分生能力强，与周围的母体组织之间形态差异显著，界限明显，其下部形成一个类似胚柄的结构。

In the seedlings time, the content of chlorophyll decreased by the deficiency of B, but the content of chlorophyll in the high efficiency cultivar decreased slowly than that of the low efficiency cultivar. This suggested that the leaves of the high efficiency cultivar can capture more light energy and the photosynthetic rate of the high efficiency cultivar decreased slowly. In the bolting time and blooming time, after two weeks of B deficiency treatment, the content of chlorophyll in the top leaves of the high efficiency cultivar decreased, and in the late time, the content of chlorophyll decreased slowly. But, the content of chlorophyll in the bellow leaves of the two cultivars had little changes. The reason may be that B in the high efficiency cultivar distributed to the propagative organ in the late growth, and the leaves were short of B.

苗期，缺硼导致甘蓝型油菜色素含量降低，且高效品种色素含量下降的幅度小于低效品种，表明营养生长阶段，同等程度的缺硼条件下，高效品种叶片对光能的收集能力以及光合速率下降的程度相对较小；苔期和花期，在两周的缺硼处理后，高效品种上部叶色素含量依然呈下降趋势，但随着生育期的推移，其下降幅度减小；而高效品种下部叶和低效品种叶片含量变化不大，可能是甘蓝型油菜进入生殖生长阶段后，高效品种将硼更多地分配到繁殖器官，而其叶片却承受了相对较大的缺硼胁迫。
