证明了在一般的紧致度量空间上，等距映射的系统，压缩映射的系统，单位圆上的自同胚映射的系统等的拓扑熵都为零，而可扩映射的系统有正的拓扑熵。

2 The package substation shall accommodate one 1500kVA 10kV/LV transformer, one 12kV 3-way RMU with extended busbar and space for adding additional way if required in future, one LV board with one incomer unit and 12 distribution units and a 30V battery and charger for motorized operation of the 12kV RMU with fault making and load break switches.

2.2.2 箱式变电站能够容纳一个1500kva 10kv/lv 变压器，一个12 kV 3路 RMU （为了以后的需要，延长母线和空间的），一个的低压板（带有一个进入单元和12个分配单元）和一个30V 的电池和充电器，这样在故障决策和负荷开关时，能机动化操作12KVRmu 。

In the third chapter, it is proved that a Minkowski plane withπ/2-property, whose unit circle is Radon curve, is an inner product space.

在第三章中，本文证明了单位圆是Radon曲线且具有π/2性质的空间是内积空间。

In this paper,it is proved that a Minkowski plane with π/2-property,whose unit circle is Radon curve,is an inner product space .

证明了单位圆是Radon曲线，且具有π/2性质的M inkowski平面，是内积空间

At present the evaluation methods of garden cities promulgated by Ministry of Construction only take hardness index to the urban green space ratio and green coverage rate,The suggestion is to establish quantized instructiveness advice for the arborous and shrub layers density of urban different function greenlands and species. It convenient for acceptance check more scientific,more normative to construction of urban greenland system. Finally it can maximum improve unit green capacity under assuring each service function.

目前建设部颁布的园林城市评审办法只对城市的绿地率和绿化率有硬性指标，建议对城市不同功能类型的绿地的乔灌木的种植密度、种类等数量值制定量化的指导性的建议，便于城市绿地系统的建设更科学，更规范，更便于验收检查，最终在能保证各自服务功能的前提下最大限度的提高单位绿地的绿量。

Such a problem need us to know whether an onto isometry between the unit spheres of Banach spaces has an linear extension to the whole space?

它是问定义在两个Banach空间单位球面到单位球面上的等距算子是否可以线性等距延拓到整个空间上？

And pH7. 5 conditions were obtained and diffract X-rays to 2. 0〓 and 1. 8〓 resolution, respectively. Both crystals are isomorphous and belong to the space group P1; only one AB-heterodimer is in the whole unit cell.

在pH 6.5和7.5两种结晶条件下，AHP IX-bp的整体结构很相似，均方差仅为0.122 〓，但在pH 6.5条件的晶体结构中，His B61具有双重构象，这种结构的变化可能与AHP IX-bp活性的pH依赖性相关。
