Foreword A mechanical engineer in a major domestic company was faced with the task of calculating the size of a steel tank for heating a factory hall with liquefied gas. In a chemical-physical table he came across the indication of the molar enthalpy of combustion in I / mol. The engineer was confused, because he simply wanted to know the "calorific value of a cubic meter". He was no longer familiar with the meaning of the mole as an SI unit of the amount of substance and the conversion to volume using the molar mass In almost all areas of the natural and engineering sciences the growth in knowledge and technologies is booming. In the last decade the curriculum of the over-grained courses of study has swelled to the limit of studyability. With environmental technology, mechatronics, software system technology, patent engineering, medical technology etc. are new interdisciplinary ones Courses of study emerged that demand a broad cross-sectional knowledge of future engineers. The traditional classification of knowledge in the conflict between natural and engineering sciences is obviously blurred. Principles of physics and chemistry that were previously repealed in the classical disciplines. Electrical engineering and mechanical engineering are increasingly merging into higher-level knowledge packages. This book is about the "basic knowledge of the engineer" and the industrial applications. This reference work is a collection of physical-chemical-technical formulas, tables and data collection in one. It accompanies you through the microcosm of technical forms and terms. Students, students , Teachers and practitioners, will find the relevant basic and specialist knowledge of the natural and engineering sciences quickly and reliably - be it in tests or when assessing complicated issues in an industrial environment. Around 6,000 keyword entries bridge the gap from subatomic particles to process engineering reactors The lexicon is divided into clear sections, which correspond to the sub-disciplines of the natural science and technology courses at European universities: I. Structure of the subject 2. Mechanics and mechanical engineering 3. Flow mechanics and mechanical processes 4. Vibrations and waves 5. Acoustics and soundproofing 6. Optics ics and lighting technology 7. Electrical engineering and technical informatics 8. Thermodynamics, thermal processes and energy technology 9. Analytical chemistry, occupational safety and environmental protection 10. Material transport and reaction technology II. Electrochemistry and surface technology 12. Keyword index The clear preparation of the material should be given in a lexical short ensure fast access times and a high density of facts. The focus is on the practical application of scientific and technical facts and formulas: broad derivations are therefore sparingly to be found. Nevertheless, the necessary depth is not waived selectively, especially since the students in today's university environment often find neither the time nor leisure to extract relevant information from prosaic textbooks. The extensive index of keywords leads purposefully from the question to the technical explanation in the index part of the corresponding specialist chapter. English translations of internationally standardized terms. Material data, application and calculation examples are intended to help reduce everyday communication obstacles in practice and training.

VI The work implements the new spelling. which has been binding since August 1, 1999. It runs counter to the hum anistic ideal of education, but finally the general "ph" is abolished! We now read graphics, telephones, polarography, photometry, graphite - and: Foton? No, in spite of all modernity: we do not want to use any national spelling against the international English spelling. Even if the orang to the .J "ke is hesitant in the USA, this lexicon continues in" Photo n "and" Phonon " And it stays with "D ifferential" and "Potentia l". My special thanks go to my esteemed colleague Prof. Dr. rer. Nat, M ATTHIAS MANDL. For the manuscript

carefully read through and enriched it with valuable additions - especially the chapters. Acoustics: and "Optics". The Vieweg publishing house, above all his former employee Mr. WOLFGANG SCHWARZ. I thank you for the professional assistance and the drafty printing of the work in the proven quality. The continuous improvement of the work in the future Aullagen is a particular concern of the author and publisher. We therefore look forward to every constructive letter.

The analysis solution is evaporated and ionized in the acetylene gas long burner; that arise. Plasma absorbs the radiated light from a hollow cathode lamp (for each element character, wave length), the light monitoring is proportional to the concentration (Lambert-Beer law), universal for analyzes in the ppm range; No trace analysis due to incomplete atomization and short residence time in the flame. Cannot be used below 190 nm because the oxygen in the air and flame gas break down by themselves. The following cannot be determined directly: Halogen e, Se, C. gaseous elements. The sample must be drawn up; grained metals are to be opened. Ox id ation levels are not distinguishable; hence As (V), Sb (V), Setl V). Te (IV) etc. - which absorb weakly or not at all - reduce beforehand. 2) G rafi trough AAS. For trace analysis. high detection limit n.

Atomic absorption gauges.

Solids are placed on a L 'vov plau fo rn inside the pipe, which is heated up by radiant heat from the pipe wall. Atomization takes place with a time delay, but advantageously in a thermally largely stabilized gas atmosphere.

Purge gas argon prevents the electrically heated graphite tube from burning off (approx. 10 V. 500 A. 3000 K). 3) hydride technology. For parental determinations with

volatile hydrides (As. se, Bi. s-, Te. Sn, etc.). The sample is hydrogenated (with NaBH4 or SnCl2); the metal hydride is atomized in a heated glass civette: the atomic absorption is measured.

Example: 52 (V = 3) -> 52 (V = 0). • Internal conversion (internal conversion. IC): radiationless deactivation through isoenergetic change in the electronic state = Weehsel into a deeper electron shell with a higher level of visual vibration (without energy change). Example: 52 (V = 0) -> 51 (v = 5) Otherwise visual oscillation relaxation is possible. • Inter-combination (intersystem crossing. ISC). Isoenergetic conversion from the singlet to the triplet state.

Outermost electrons with parallel spin. Paramagnetic spin moment. No ground state To for s orbitals (PAULl principle). Triplets are lower in energy than singlets and are stable for up to seconds. 2) deactivation. The following deactivation processes are competing: • Fluorescence: radiation emission with transition to a lower singular state: 5; +1 -> 5; . In the case of preceding relaxation, the wave is always longer than the absorption. Transitional prohibition: Spin reversal is prohibited (untrustworthy)! See * selection rule. • Phosphorescence: radiation emission from the triplet state (TI -> 50). Go ahead suggestion. Intersystem crossing. Visual vibration relaxation. • Luminescence: umbrella term for fluorescence and phosphorescence. • Photo reaction: the electrically excited molecule reacts to form products.

Unit cell or BRAVAIS-Gitler: smallest repeatable unit of a crystal lattice: a total of 14 different types, described by the atomic spacing of the coordinate axes and the angle between the crystal axes. • 7 primary grids: only the corner points are occupied. • 7 centered grids: in addition to the corner points, positions on the inside are occupied. The corner points e of the elementary cells in the crystal lie on a family of parallel network planes. 5. "Crystal system 6th network level = crystal lattice level: contains the crystal building blocks in a regular arrangement; defines the" founding constants as axis segments on the crystal axes; determined by three grid points that do not lie on a line n. Convention: forward, h right, C up. 7. Weijl -Jlldex: multiple s of the lattice constant en a .b .c (= axis intercept on the basis vectors). 8. Miller index: integer reciprocal values ​​h. k .l the white indices: Rauml. Location of the network levels.


Crystal lattice, reciprocal Girrer. Analogous to the vector description of the crystal lattice;: = u a + v h + we die vector. Description of the diffraction pattern. The BRAGG equation says nothing about the orientation of the bent X-ray chairs. but the vectorial network levels are probably spaced apart. Reciprocal lattice plane spacing (for II = I)
