现在,我们可以使用玻尔原子来演示能量量化。更简单的方法是考虑一个一维问题,即一个电子被限制在一个盒子里。当我们研究量子力学本身时(即通过求解所谓的薛定谔方程),我们会发现盒子里的电子问题在数学上等同于弦上的波问题。在波动图中,这种对应关系是显而易见的,因为电子是波,而盒子是边界条件。然后,电子的(非相对论)能量由其动能给出:
微型计算机有三种基本类型: 台式系统单元:包含系统的电子元件和选定的辅助存储器。鼠标、键盘、显示器等输入和输出设备位于系统单元外部。它可以水平或垂直放置。垂直单元称为“塔式模型”。 笔记本系统单元:便携且小得多。它们包含电子元件、选定的辅助存储器和输入设备(键盘和指点设备)。显示器位于系统单元外部,通过铰链与其相连。 个人数字助理 (PDA) 系统单元:最小,设计为一只手掌大小。它包含整个计算机系统,包括电子元件、辅助存储器和输入和输出设备

18B.1 Iowa smart planning principles. State agencies, local governments, and other public entities shall consider and may apply the following principles during deliberation of all appropriate planning, zoning, development, and resource management decisions, except that nothing in this section shall be construed to expand the eminent domain authority of a state agency, local government, or other public entity beyond that which is authorized under chapter 6A or 6B : 1. Collaboration. Governmental, community, and individual stakeholders, including those outside the jurisdiction of the entity, are encouraged to be involved and provide comment during deliberation of planning, zoning, development, and resource management decisions and during implementation of such decisions. The state agency, local government, or other public entity is encouraged to develop and implement a strategy to facilitate such participation. 2. Efficiency, transparency, and consistency. Planning, zoning, development, and resource management should be undertaken to provide efficient, transparent, and consistent outcomes. Individuals, communities, regions, and governmental entities should share in the responsibility to promote the equitable distribution of development benefits and costs. 3. Clean, renewable, and efficient energy. Planning, zoning, development, and resource management should be undertaken to promote clean and renewable energy use and increased energy efficiency. 4. Occupational diversity. Planning, zoning, development, and resource management should promote increased diversity of employment and business opportunities, promote access to education and training, expand entrepreneurial opportunities, and promote the establishment of businesses in locations near existing housing, infrastructure, and transportation. 5. Revitalization. Planning, zoning, development, and resource management should facilitate the revitalization of established town centers and neighborhoods by promoting development that conserves land, protects historic resources, promotes pedestrian accessibility, and integrates different uses of property. Remediation and reuse of existing sites, structures, and infrastructure is preferred over new construction in undeveloped areas. 6. Housing diversity. Planning, zoning, development, and resource management should encourage diversity in the types of available housing, support the rehabilitation of existing housing, and promote the location of housing near public transportation and employment centers. 7. Community character. Planning, zoning, development, and resource management should promote activities and development that are consistent with the character and architectural style of the community and should respond to local values regarding the physical character of the community. 8. Natural resources and agricultural protection. Planning, zoning, development, and resource management should emphasize protection, preservation, and restoration of natural resources, agricultural land, and cultural and historic landscapes, and should increase the availability of open spaces and recreational facilities. 9. Sustainable design. Planning, zoning, development, and resource management should promote developments, buildings, and infrastructure that utilize sustainable design and construction standards and conserve natural resources by reducing waste and pollution through efficient use of land, energy, water, air, and materials. 10. Transportation diversity. Planning, zoning, development, and resource management should promote expanded transportation options for residents of the community.
