So the data transferred in the network can be classified into multi-data (real-time service) and general-data.

这些数据分为有实时性要求的多媒体数据和时间不受限的常规数据。

The CO2 uptake rate of plants is affected by the plant species and environmental conditions such as photosynthetically active radiation, temperature, water and nutrient contents. PAR is the most immediate environmental control on photosynthesis while air temperature affects both photorespiration and dark respiration. In the natural condition, PAR and temperature play an important role in net CO2 uptake. The effects of PAR and air temperature on the CO2 uptake of Pterocarpus macrocarpus grown in a natural habitat were studied in the present work. Due to many uncontrollable factors, a simple rectangular hyperbola could not represent the measured data. The data were divided into groups of 2℃ intervals; CO2 uptake in each group may then be related to PAR by a rectangular hyperbola function. Using the obtained functions, the effect of PAR was removed from the original data.

用涡度相关法对亚热带红壤丘陵区人工针叶林的二氧化碳、水、热通量进行了观测，重点分析了23m、39m两层高度的观测结果，同时把观测期分为春季和冬季两个不同时间段作了对比：结果表明，不管冬季还是春季，39m高度所测的总通量值和夜间通量值都要小于23m的观测值，这种通量差别表明：23m高度的观测结果更接近当地生态系统与大气之间的通量交换值，在此种生态类型条件下用涡度相关法测碳通量时，在23m、39m两层高度之间仍然存在大气平流现象；该试验区植被在冬季仍然可以进行光合作用，而且光合作用所吸收的CO2大于呼吸作用所排放的CO2，因此该种生态系统在冬季仍表现为碳汇；春季的碳通量值为冬季的2倍以上。

By using the fauna of digital television broadcasting channel, sue as mass data transmission, less resource occupied than Internet, and QoS guarantee, this system is de signed base on the Redbud DTV front-end sys tem developed by Shenzhen institute of Tsinghua university.

If want the data of built-in in HTML page of the static state trends, and these dynamic data are the word that will offer by the program such as ASP, PHP, so every time a person visits your website, the server is about to carry out and handle Tongji.asp document, from the data with draw-out and relevant database, reexport shows to the webpage, if tens of thousands of person is visited at the same time, be about to be carried out tens of thousands of times, consequence cans be imagined.

假如要在静态的HTML页面里嵌入动态的数据，而这些动态的数据是由ASP、PHP等程序来提供的话，这样每次有一个人访问你的网站，服务器就要执行并处理一次tongji.asp文件，从数据库抽取相应的数据，再输出给网页显示，假如有几万个人同时访问，就要执行几万次，后果就可想而知。

The method includes the following steps: firstly, a spherical neighborhood of present sample points is established by using the geometric spherical-modelling theory and all the sample points contained in the spherical neighborhood are adopted as candidate neighbor points, thus not only preserving the effectivity of the dimension reduction capability when data sets are sparse but also getting the advantages of low-sensitivity to isolated points and good stability of the preserved topological structure; then a data relevance matrix more matching semantics can be obtained by relevance measurement based on route clusters to update the candidate neighbor points in the spherical neighborhood and optimize the regular neighborhood space of the present sample points, thus improving the phenomenon that the dimension reduction of sample sets provided with folded curved faces is apt to suffer the integrated-structure distortion in case of heterogeneous data distribution.

首先利用几何开球原理建立当前样本点的球状邻域，将包含在球状邻域内的所有样本点作为候选近邻点，不但能够保持在数据集稀疏情况下的降维性能的有效性，而且具有对孤立点敏感性不高、保留拓扑结构稳定性好的优点。然后利用基于路径聚类的相关性度量得到更符合语义的数据相关性矩阵，用来对球状邻域内的候选近邻点进行更新，优化当前样本点的规则邻域空间，改善了当数据不均匀分布时在带有折叠弯曲面的样本集上降维容易出现整体结构扭曲的现象。
