The basal diameter, height of aerial stem, leaf length at middle stem, leaf width at middle stem, internode length at middle stem, internodes number and panicle length of 30 plants from every population were recorded. The statistics of morphological characters showed that the distribution trends of the averages of morphological characters are similar among populations. However, the coefficients of variation within population of 7 morphological characters were very different. The CV of internodes was largest and the CV of height was smallest within population. F-statistics showed that the differences of all morphological characters among populations were significant (P.01). But the differences among populations were different between different groups. The cluster analysis proved that all populations could be divided into three types: salty reed, freshwater reed and giant reed.

对来自每个种群的30个个体的基径、株高、中部叶长、中部叶宽、中部节间长、节间数、穗长7个形态特征的统计分析表明:各形态特征平均值在种群间的分布趋势相似,但变化幅度不同,株高、叶长等营养特征变化较大大,生殖特征穗长的变化较小;7个形态指标在种群内的平均变异度从大到小依次为中部节间长、中部叶宽、穗长、中部叶长、基径、节间数、株高,种群内的平均形态变异度与生境异质性有关;7个形态指标在种群间均差异显著,但多重比较分析显示显著差异主要存在于BZH、淡水生境种群和盐渍化生境种群之间,在相似生境种群间的形态差异不显著;以形态特征为依据的聚类分析支持将15个种群分为三类:盐生芦苇、淡水芦苇和巨型芦苇。

2Spatial learning and memory:In the cued condition, the avoidance latency in the colzapine-exposed group was significantly shorter than the control group in the block 2(p.05),however there is no difference on block 3 between two groups;In the place condition,the clozapine-exposed group prrferred to finding the submerged platform in the serial blocks(P.01);in reversal condition,the filial rats exposed the clozapine had no advantage on finding out the submerged platform in block2,3,4 except of the block l(p.01),the further statistic analysis reminded that it is just the first trial that the filial rats in clozapine-exposed group had the advantage to find out the submerged platform in reversal condition (F=4.86, PO.01).it isimplicated that the clozapine exposed in the gestation lead to the improvement on the acquiry and consolidation.however the acquired memory seems not to be maintained.

OI;提示用药组大鼠的子代记忆巩固能力较对照组好;固定平台再认定位实验中,用药组大鼠的子代首轮寻找平台的潜伏期较对照组明显缩短(F一巧。04,P 。01),以后数轮成绩没有差别。进一步的统计显示,氯氮平孕期使用组大鼠在再认阶段仅仅是首个方向更快的发现平台(F二486,P.01),提示氯氮平孕期使用提高了记忆的获取,但这种已经获取的记忆优势并没有得到保持。

Evidence suggests that 1 under more stable stratification, the basic flow, if moving faster at low and high levels (particularly in the presence of jets there), allows a resulting meso-β unsteady wave to propagate eastward with respect to basic flow and even at greater velocity compared with it; 2 vertical windspeed shear of basic flow causes instabilities of the TWT perturbation; 3 considering the second derivative of basic-flow wind with respect to z (denoted by zz≠ 0 which is simply given as β* hereafter) the expression for the phase velocity of vortex Rossby wave is obtained, which is unidirectional in propagation with respect to basic flow; 4 VRoW has its physical origin from β*, i.e., from z-varying heterogeneities of y-direction averaged vorticity of the basic flow field; 5 VRoW phase velocity is associated with zonal wave number k, its energy is dispersive and the group velocity exists in the x direction; 6 when windspeed meets the condition of β*, TWT disturbance instability may be that of mixed VRoW and gravity wave; 7 if basic flow is subject to linear shear but does not meet the condition of β*, the TWT instability is that of inertia-gravity wave.

在大气层结比较稳定的情况下,如果基本气流在低层和高层较大(有可能存在低空急流和高空急流),此时产生的β中尺度不稳定扰动相对于基流向东传播,甚至于快速向东传播。基本气流在垂直方向上的风速切变对于中尺度横波型的扰动起着不稳定的作用。如果考虑基流的二次切变,可以得到涡旋Rossby波的相速度表达式,涡旋Rossby波相对于基本气流是单向传播的。涡旋Rossby波产生的物理根源是基本流场的风速二次切变,亦即基本流场y方向的平均涡度在空间z方向上的不均匀所致。涡旋Rossby波的相速度与纬向波数也有关,它的能量是频散的,其在纬向x方向也存在群速度。在基本流场的风速存在二次切变时,横波型不稳定可能是混合的涡旋Rossby重力波的不稳定;而在基本流场的风速仅仅存在线性切变,不存在二次切变时,横波型扰动的不稳定则是重力惯性波的不稳定。

研究结果表明:硬麦加工后淀粉破损率高,而软麦则相对较低,硬麦粉的淀粉破损率较软麦粉高出 2 0 %左右;面粉越细则淀粉破损率越高;研磨道数越多,研磨强度越大,淀粉破损越严重;齿辊所造成的淀粉破损程度要比光辊为重,但差距不是很大;撞击机在正常生产时对淀粉破损影响较小,如反复撞击也会使破损淀粉增加,但其影响程度较研磨强度缓和。
