By introducing the set theory and basic methods of the solid geometry and adopting the Verman three-dimensional structure ideology innovatively, the standards system of Hainan National Breeding and Multiplication (HNBM) was studied with the four-dimensional structure and integration by combining with the time dimension. The four-dimensional structure standards system will be useful for guiding the construction of the HNBM standards system, carrying on the division of labor and realizing the dynamic development of the standards system. The standards set of HNBM helps to computer programming and information management.展开更多

Based on the constitutions in 193 countries, this paper aims to examine the fundamental situation of incorporating environmental rights into a constitution. It has been concluded that environmental protection as a right is written into a constitution in three aspects, namely, as a constitutional right, a civic duty, and a national policy, principle or social goal. Through summarizing these, this paper argues that including environmental rights in a country’s constitution is the means by which all citizens shall enjoy a good, healthy, sustainable and harmonious environment suitable for their development, have timely and comprehensive access to reliable information about environment, participate in making public decisions related to the environment, and ask for legal remedies and compensation for any infringement on their environmental rights, or injury or damage to their environmental property. But even after environmental rights are incorporated into a constitution, there may be theoretical and practical difficulties in their implementation.展开更多
