The spatial-temporal distribution of NPP along NECT and its response to climatic change were also analyzed. Results showed that the change tendency of NPP spatial distribution in NECT is quite similar to that of precipitation and their spatial correlation coefficient is up to 0.84 (P 0.01). The inter-annual variation of NPP in NECT is mainly affected by the change of the aestival NPP every year, which accounts for 67.6％ of the inter-annual increase in NPP and their spatial correlation coefficient is 0.95 (P 0.01). The NPP in NECT is mainly cumulated between May and September, which accounts for 89.8％ of the annual NPP. The NPP in summer accounts for 65.9％ of the annual NPP and is the lowest in winter. Recent climate changes have enhanced plant growth in NECT. The mean NPP increased 14.3％ from 1980s to 1990s. The inter-annual linear trend of NPP is 4.6 gC·m-2·a-1, and the relative trend is 1.17％, which owns mainly to the increasing temperature.

结果表明：(1)NECT样带植被NPP的空间变化趋势同降水量的空间变化十分相似，由东到西逐渐降低，二者在空间上的相关性达到了0.84(P《0.01)，说明NECT样带的植被NPP在空间分布上主要受水分趋动；(2)NECT样带植被NPP的年际变化主要是由各年份夏季NPP的变化造成的，夏季对NECT样带植被NPP的年际增长贡献率最大(67.6％)，二者之间的相关性达到了0.95(P《0.01)；(3)NECT样带的植被NPP积累期主要发生在5-9月份，这5个月的NPP占了全年NPP总量的89.8％，整个夏季(6-8月份)的NPP占了全年的65.9％，冬季(12-2月份)的NPP最低，基本为0；(4)近19年来的气候变化促进了NECT样带的植被生长，从1980年代到1990年代，NPP显著增加，年代际相对增长率为14.3％，平均年际绝对增长趋势为4.6 gCm-2(a-1，相对增长趋势为1.17％，这主要是由温度升高引起的。

Test and analysis show that, the distribution patterns of the tangent veloctiy fields in the big cone area and the small cone area, which are comprised of para-free vortex and para-forced vortex, are basically identical without a change of the radius of the boundary surface; with the increase of the angle of the small cone, the para-free vortex area decreases and the para-forced vortex area increases, and the emulsifiability of the fluid drips increases with the increase of velocity gradient; the tangent velocity increases with the increase of inlet flow, and the maximum tangent velocities of both the big cone area and the small cone area are 4.94 times of the inlet flow; and the maximum tangent velocity increases with the increase of the split ratio and with the radius of the boundary surface not changed.

试验分析表明，大锥段和小锥段切向速度分布规律基本相同，均由准自由涡和准强制涡构成，分界面半径rm没有变化；随着小锥角θ的增加，准自由涡区缩小，准强制涡区扩大，速度梯度增加会加大液滴的乳化程度；随入口流量增加，切向速度增大，经拟合得出大锥段和小锥段的最大切向速度均为入口流量的4.94倍；分流比加大，分界面半径基本不变，最大切向速度增加。

The modulation of sound properties over a wide range of time scales is one of the most obvious characters of Oscine passerine\'s vocal, whose song contains many different kinds of syllables that consist of many more multiple song phrases. In oscine passerine, ipsilateral projections of RA to NXIIts innervates the ipsilateral syringeal muscles exactly, and thus they have strong ability of vocal control with variable tones, high frequency and higher lever of quality.

鸣禽鸣啭的最大特点之一便是其单次鸣唱时间长，鸣唱所包含的音节数量和音节种类繁多，因而由这些音节所组成的句型结构也是复杂多样富于变化，且由于NXIIts严格的侧别控制(每一侧核团只支配同侧鸣肌)，使其具有更强的控声能力，其鸣声音调变化幅度大，频率高，品质因数大，音色好，因而其鸣声也悦耳动听。

Distribution of detailed flow parameters such as liquid velocity and stream function were measured by this method.

认为反应器上升段表观气速对液相水平速度和垂直速度均有影响，其中对液相垂直速度的影响更大：表观气速增大，液相最大垂直速度一般增大，但这一变化规律并不是单调的；PIV对折流区的观测反映了该区域流场在气相通入后的最初25 s内的变化历程，流场发展的快慢与进气口的气速有关，气速越大，流场发展得越快。

The critical nitrogen content in heading period was used to calculate the biggest accumulation quantity of nitrogen. The latent distribution index of leaf and stem, which was the variety heredity parameter, were used to distinguish the difference in nitrogen assignment in different varieties. The dynamic content of the nitrogen accumulation before anthesis could be described with a Richards model. The dynamic content of the nitrogen remobilization in leaf with leaf area index could be described with a power model, and the nitrogen absorption of grain from soil with dry weight could be described with a power model. The dynamic content of nitrogen density in stem and spike with physiological development time could be described with a nonlinear model.

As the spectral width (Full width half maximum: FWHM) range from 6nm to 60nm, the simulation results show that the effect of the variation of the FWHM upon the output is small. When only the Verdet constant is considered, the output increased slowly with the increase of the FWHM. The simulation results are verified by the experiment.

当光源光谱宽度在6nm到60nm之间变化时，不同谱线宽度光源对系统输出影响的仿真结果表明：光源谱宽变化对系统输出的影响相对于其单色模型来说，相对变化小于10~(-3)，因此光源谱宽变化对系统输出的影响较小；如果完全消除了线性双折射和反射相移，则系统输出随光源谱宽的增加有微弱的增加：由于Verdet常量的影响最大，所以系统输出随光源谱宽的增加有微弱的增加；实验结果验证了该结论。
