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。

Until the airstrip was operational, aerial evacuation of the most serious cases had been limited to those that could be flown out by the nine helicopters and 10 light aircraft of Major Gottschalk's VMO-6, which also had many other missions to perform.

在简易机场投入使用之前，重伤员的空运撤离只能很有限地由高特斯科克少校VMO-6飞行中队的9架直升机和10架轻型飞机进行，而这个飞行中队同时还担负着其它的飞行任务。

The same procedure can be used to remove the graininess of highly enlarged photographs, which is of value e.g. in aerial photo reconnaissance

同样的步骤可以用来去掉放大很多倍的照片上的颗粒特性，这在航空摄影侦察中是有价值的。

The shotguns were also used for aerial gunnery training.

The US source further pointed out that Harpy unmanned aerial vehicles obtained by China from Israel in 2001 are now operational.

美国同时指出，2001年从以色列得到的"哈皮"无人机已经在中国服役。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
