According to the statistics,There are 28 species of the key national preserved plant,which belong to 14 families 23 genera,of which there are 3 families 7 genera 10 species of gymnosperm and 11 families 16 genera 18 species of angiosperm,of which 3 species belong to the first grade of protected of plants and 25 species belong to the second grade of protected plants.

河南省处于温带与亚热带地区，植物资源丰富。据统计，国家重点保护植物28种，隶属14科23属，其中裸子植物3科7属10种，被子植物11科16属18种，国家一级重点保护植物3种，国家二级重点保护植物25种。

Also protect circuits against loss of hall signal, low battery voltage, over current are included.

此外，还包括了霍尔传感器断线检测、电池欠压保护、过流保护等保护功能。

Moreover, The Harte Research Institute, which is committed to supporting and promoting the conservation of the natural resources in the Gulf of Mexico, the International Union for the Conservation of Nature, the Marine Geospatial Ecology Lab at Duke University, that researches the physical structures of the territory in respect of marine life in our Oceans.

另外，旨在支持倡导保护墨西哥湾自然资源的哈特研究中心、世界自然保护联盟、为保护海洋生物而研究地表物理结构的杜克大学海洋地理空间生态学实验室也参与了这项工程。

For protecting the signal transmitting fiber in downhole high temperature and pressure environment, an epoxy-free package method based on hermetical bonding of quartz ferrule and fiber is used and Polyimide coated fiber and stainless steel protecting tubing are adopted.

我们采用金属—石英管的机械压力密封和石英管—光纤的激光热熔无胶密封结构，保证了传感器导压腔和耐高温光纤不锈钢保护套管的可靠密封，提高了整个系统的可靠性和使用寿命；采用不锈钢套管保护聚酰亚胺材料涂敷的耐高温光纤传输传感信号，解决了耐高温和保护光纤的问题。

The patterns and changing of The Changbai Mountain forest ecosystem services affected by human activities were explored in this paper. The impact of human activities on Changbai Mountain forest ecosystem services include positive effects and negative effects, they were expatiated in the paper. The positive effects include protecting idioplasm resources, wildlife and natural landscape, and forest fireproofing, and so on. The negative effects contain the capacity of biodiversity, purifying environment, regulating climate, buffering disaster and supplying product etc.

摘 要：本文分析了人类活动对长白山森林生态系统服务功能影响的方式和利弊，并将其影响分为正面影响和负面影响进行阐述，其中正面影响为生物种质资源保护、野生动植物资源保护、森林防火、自然景观保护等；负面影响为生物多样性维持能力下降、影响生态系统对大气和气候的调节过程、削弱净化环境的能力、影响水文调节能力、影响灾害缓冲能力、降低生态系统产品供给能力、改变营养物质的贮存和循环过程等。

The property rights of rural land are not protected by laws. Nor are they protected by Property Rules , Liability Rules , or even Inalienability Rules.

这种制度安排使农地产权成为一种失去法律防护的权利，它既不能依据财产规则来保护，也不能以责任规则来保护，甚至不能得到"不可转让规则"的保护。

As far as the legal documents of the central government are concerned, the provisions of the constitution, organic law and the law in environmental protection field are abstract and inexplicit. While combining these documents with administrative regulations and other informal sources, we find that the boundary of power of the State Environmental Protection Administration of China is very definite. But the boundary of other environmental protection administrations is unclear.

就中央法律文件对建设项目环境影响评价文件审批权的配置而言，宪法、组织法和环境保护领域法律的规定是比较抽象而不明确的，但当结合行政法规、规章以及其他规范性文件进行考察时，就会发现，中央法律文件对于国家环境保护行政主管部门审批权力的配置并不是不清楚，而是十分明确的；但对各级地方环境保护行政主管部门的权力配置则主要是授权性的规定。

Then, considering the knowledge represented by a set of frequent patterns, we investigate the problems of preserving sensitive patterns in data sharing, hiding sensitive patterns in frequent pattern sharing, and also blocking inference channels in frequent pattern sharing. The main contributions are as follows:(1) For the problem of preserving anonymity in data sharing, we propose a clustering-based approach for implementing l-diversity.

本文首先研究了数据共享中匿名保护问题，接着以频繁模式为知识的表现形式，研究了数据共享中的敏感模式保护，频繁模式共享中的敏感模式隐藏，以及频繁模式共享中的推理控制等问题，主要的研究成果如下：(1)针对数据共享中的匿名保护问题，提出了一种基于聚类的l-多样化实现方法。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
