查询词典 ravine stream

Under the background of digital DEM of maor mountain area, and through the program of Avenue in Arcview, the result of potential ravine highly inosculates with the real ravine. With the comparison of potential ravine and real ravine, it can reflect the developing tendency of ravine in this area. Through positioning with GPS and investigation in this area, we can divide the potential ravine of this area into three forms, that is parallel ravine area steep ripe ravine area and evenness swamp area. It can provide scientific reference for forest management and tree planting, and it is a new theory to prevent soil and water loss, and carry through the ravine controlling by people.

在数字化生成的帽儿山地区DEM基础上，通过二次开发生成的潜在沟系，具有与现实沟系高度的吻合性，并通过与现实沟系的比较，能客观的反映出该地区沟系发生、发展的趋势，借助于GPS的定位及实际踏查研究，可将帽儿山地区的潜在沟系划分为平行沟系区、陡坡显沟区和平坦沼泽区三种类型，可为合理的森林经营和植树造林提供科学的借鉴，并为防止水土流失，进行沟系治理提供了新的理论依据。

In this paper, each of single data stream that is included in data streams has same attributes set as other,the unit of single data stream is tuple,and same attributes set is included in each of these tuples.Reservoir algorithm is used to sample from these single data stream respectively,then some multiple snapshot windows are constructed,the relationship between these single data stream and multiple snapshot windows is bijective mapping,the relationship between attributes that are included in tuple and snapshot windows that are included in relative multiple snapshot windows is bijective mapping,and the relationship between basic windows that belong to same snapshot window and the attribute values that come from different single data stream is bijective mapping as well,that is,these attribute values come from same attribute that is comprised by different single data stream.

针对以元组为单位流入的具有相同属性集的多支单数据流组成的多数据流，提出了分别对每支单数据流进行蓄水池抽样，构造一一对应于各单数据流的若干个多快照窗口，即两者之间是双射关系，可以将多快照窗口串行置于主存中，将元组包含的属性与多快照窗口中的各个快照窗口一一对应，且使得同一快照窗口中的各基本窗口与取自其对应的单数据流的属性值样本一一对应，然后对这些相互独立的样本进行方差分析。

体育生态系统是一个由人—体育—环境构成的复合社会生态系统，具有整体性、层次性、开放性、目的性、有序性、动态性、耗散性以及高度人工化的特征；其能量流动不仅有能量流、物质流、信息流的传输和转化，还有价值流、知识流、能力流的富集，并不断地促进各层次体育的发展。

The symmetric algorithm is a traditional algorithm, it is easy and efficient, and so it is still being popular used. The stream cIPher and the block cIPher are two part of the symmetric algorithm. The symmetric algorithm uses the key to control the key stream generator, and then the generator produces a random stream. We can get the cIPher by xor the message and the random stream by bit. In the field of communication and code, the stream cIPher has always been the key cIPher of the military affairs and foreign affairs.

对称密码体制分为序列密码和分组密码两类，序列密码以密钥控制密钥流发生器，产生一随机序列，用这个随机序列和明文信息逐位异或，就得到密文，其加密单元为比特。

The coding device for DVD system and other record systems includes audio and video coder to convert the input audio and video data into audio and video data stream; system coder to convert the audio and video data stream into audio and video data stream of, say, MPEG format; audio and video data stream buffer before the system coder to store audio and video data stream generated during one set period by the audio and video coder; and buffer downstream the system coder with relatively low capacity and capable of performing the record operation of pre-trigger.

提供了在DVD系统等记录系统中使用的编码设备。该编码设备包括分别把输入音频和视频数据转换成音频和视频数据流的音频和视频编码器、把音频和视频数据流转换成例如MPEG格式的音频／视频数据流的系统编码器。还包括系统编码器上游的音频和视频流缓冲器，它们分别存储音频和视频编码器在一段预选的时间内产生的音频和视频数据流，从而使系统编码器下游的缓冲器的容量较小并有效地进行预触发器记录操作。

The method comprises A: separately configuring different common channel priority indication for different service data stream transmitted on same dedicated service channel; B: according to sequence from high to low of public channel priority indication for different data stream, priorly scheduling public channel high priority indication service data stream for transmitting at every moment; C: if service data stream of low common channel priority indication being not scheduled in a preset reference time period, then upgrading the service data stream common channel priority indication, then return to B.

分别为在同一专用业务信道上传输的不同业务数据流配置不同的公共信道优先级指示；B。在每一时刻，所述专用业务信道按照不同业务数据流的公共信道优先级指示由高至低的顺序，优先调度公共信道优先级指示高的业务数据流进行传输；并C。预设一参考时间段，若公共信道优先级指示低的业务数据流在所述参考时间段内总没有得到调度，则将该业务数据流的公共信道优先级指示升高，然后返回B。

The system only proceeds re-editing for the tail of one stream and the front of another stream which across the editing point in editing operation to generate single stream by combination two streams, and utilizes rest of the stream as formerly, thus to reduce the worsening of signals quality caused by re-editing for the stream to the lowest.

在合并两个流产生单个流的编辑操作中，系统只对跨越编辑点的、一个流的尾部以及另一个流的前部进行重新编码，并且照原样使用流的其余部分，从而把对流重新编码而造成的信号质量的恶化降至最低。

It took nearly three-quarters-of-an-hour to climb out of this ravine. A small path led to the Incense Mills and the rushing stream was forded for the last time near a small farm. Passing the village temple of Wen Shu Ssu, the path wound in and out through the Mill Valley. Here the stream flows round a cone-shaped hill, beyond which were the towering heights of the Ma Erh shan (马耳山, Horse-Ear Hill).
