THE CONTROL VALUE OF THE DEFLECTION OF THE EMBEDDED CYLINDRICAL STRUCTURE, WHICH IS THE MAXIMUM DEFLECTION ALLOWED FOR STABILITY OF THE CYLINDER, IS A VITAL QUANTITY OF STABILITY CALCULATION. THE DEFLECTION AND THE SOIL PRESSURE ON THE EMBEDDED CYLINDER WERE INVESTIGATED BY MODEL EXPERIMENT. WHEN THE INCLINED ANGLE OF CYLINDER IS LESS THAN OR EQUAL TO 0. 25°, THE EFFECTIVE ANTI-OVERTURNING RATIO INCREASES GRADUALLY AND REACHES THE MAXIMUM. WHEN THE INCLINED ANGLE OF CYLINDER IS MORE THAN 0.25°, THE EFFECTIVE ANTI-OVERTURNING RATIO DECREASES GRADUALLY. THE CONTROL VALUE OF INSTABILITY OF THE CYLINDRICAL STRUCTURE APPROXIMATES 0. 2°, AND THE BEARING STRESS AT THE BACK EDGE OF THE CYLINDER IS EQUAL TO ZERO. 相似文献

Exploring the Relationship Between Policy and Media: A Case Study of Road Pricing in the Netherlands
THE ROLE AND INFLUENCE OF MASS MEDIA IN PEOPLE’S LIVES HAVE ALWAYS BEEN A TOPIC OF CONCERN TO EVERYONE.IN THE FIELD OF MEDIA RESEARCH,THE RELATIONSHIP BETWEEN THE MEDIA AND POLITICS HAS ALWAYS BEEN THE SUBJECT OF DISCUSSION AND RESEARCH BY SCHOLARS.THIS STUDY MAINLY USES THE NETHERLANDS ROAD PRICING POLICY AS A CASE TO EXPLORE THE RELATIONSHIP BETWEEN MEDIA AND POLITICS IN POLITICAL ACTIVITIES BY RESEARCHING THE CHANGES AND INFLUENCES OF THE MEDIA IN THIS POLITICAL ACTIVITY.THIS PAPER MAINLY SELECTS THE CHANGES AND INFLUENCES OF THE DUTCH MEDIA IN TWO MAJOR ROAD PRICING POLICY ACTIVITIES DURING THE 12 YEARS FROM 1998 TO 2010 THROUGH LITERATURE RESEARCH AND OTHER METHODS.IN THIS WAY,IT CAN EXPLORE THE RELATIONSHIP BETWEEN MEDIA AND POLITICS. 相似文献

BY USING THE OUTPUT INDUCTORS AND BODY CAPACITANCES WITHOUT ADDING ANY COMPONENT COMPARED WITH HARD SWITCHING SYNCHRONOUS RECTIFIER,THE TOPOLOGY OF A SOFT SWITCHED SYNCHRONOUS RECTIFIER WITH PHASE-SHIFTED FULL BRIDGE ZERO VOLTAGE SWITCHING DC/DC CONVERTER IS PROPOSED. THE CONVERTER EFFICIENCY IS MAXIMIZED DUE TO SOFT SWITCHING OF THE FULL BRIDGE MOSFETS AND THE SYNCHRONOUS MOS-FETS, AND ALSO THE LOW CONDUCTION LOSS OF SYNCHRONOUS MOSFET. THE OPERATION PRINCIPLES OF THE CIRCUIT ARE ANALYZED IN DETAIL AND THE SMALL-SIGNAL MODEL IS DERIVED, ALSO THE CONVERTER DYNAMIC CHARACTERISTICS ARE ANALYZED. FREQUENCY RESPONSES OF TRANSFER FUNCTIONS UNDER DIFFERENT VALUES OF TRANSFORMER PRIMARY LEAKAGE INDUCTANCE ARE DISCUSSED. THE EXPERIMENTAL RESULTS WERE OBTAINED FROM A 400 V INPUT AND 100 A/12 V OUTPUT DC/DC CONVERTER OPERATING AT 100 KHZ. THE RESULTS SHOW THAT THE CONVERTER EFFICIENCY IS 2% HIGHER IN RATED POWER THAN TRADITIONAL DIODE RECTIFIER. 相似文献

Natural and Treated FeS2 in Li/FeS2 Coin Cell 总被引：1，自引：0，他引：1
TREATED FES, SAMPLES WERE PREPARED BY NATURAL FES, SAMPLES WHICH WERE GROUND FIRST, HEATED IN NITROGEN AND THEN WASHED IN ACID. THE LEVELS OF IMPURITY ELEMENTS, PRIMARILY PRESENT AS METALLIC OXIDES AND SULFIDES, ARE HIGHER IN THE NATURAL FES, THAN THOSE IN THE TREATED SAMPLE. SCANNING ELECTRON MICROSCOPY SHOWS THAT THE GRAIN SIZES OF TREATED FES, PARTICLES ARE SMALLER THAN THOSE OF NATURAL FES, PARTICLES. THE ELECTROCHEMICAL PERFORMANCE OF LI/TREATED FES, CELLS IS ATTRIBUTED TO THE SMALLER GRAIN SIZES AND HIGHER PURITY OF TREATED FES, PARTICLES IN COMPARISON TO THE NATURAL FES, SAMPLE. 相似文献

Torsional Oscillation Characteristics of Rotary Shafts Based on Torsion and Bending Coupled Vibration 总被引：1，自引：0，他引：1
THE TORSIONAL OSCILLATION CHARACTERISTICS ON THE BENDING AND TORSION COUPLED VIBRATION OF ROTARY SHAFT SYSTEM WERE INVESTIGATED USING THE ELASTO-DYNAMIC THEORY AND OTHER MATHEMATIC METHODS, SUCH AS DIFFERENCE APPROACH, FOURIER TRANSFORM, AND WAVELET TRANSFORM. IT IS CONCLUDED THAT MASS ECCENTRICITY AND OTHER EXCITING MODALITIES AFFECT THE BENDING AND TORSION COUPLED VIBRATION OF ROTARY SHAFTS. TORSIONAL VIBRATION CAUSED BY BENDING VIBRATION FEATURES LINEARITY ALONG WITH THE CHANGE OF AMPLITUDE OF BENDING VIBRATION. MEANWHILE, ENERGY SPECTRUM CONCENTRATES ON HIGH FREQUENCY ARE-A WITH THE WAVELET ANALYSIS. 相似文献

STABILIZED ZNTIO, WAS PREPARED BY DOPING MAGNESIUM OXIDE THROUGH TRADITIONAL SOLID-STATE REACTION. THE EXPERIMENTAL RESULTS INDICATE THAT ZINC TITANATE CRYSTALS DOPED WITH MAGNESIUM OXIDE GROW WELL AND THE DECOMPOSITION INTO ZN2TIO4 AND TIO2 IS RESTRAINED THROUGH TRADITIONAL SOLID STATE REACTION. BY ADJUSTING MOLAR RATIO OF MGO, BETTER PROPERTIES CAN BE OBTAINED. THE DIELECTRIC PROPERTIES OF THE CERAMICS DOPED WITH 30% MGO( MOLAR PERCENTAGE) SINTERED AT 1 060 ℃ ARE AS FOLLOWS:THE VALUE OF QUALITY FACTOR IS GREATER THAN 20 000(6. 5 GHZ), THE TEMPERATURE COEFFICIENT OF RESONANCE FREQUENCY IS ABOUT 2 × 10-6/℃, THE DIELECTRIC CONSTANT RANGES FROM 18 TO 22. BESIDES, IT IS PROVED THAT HEAT TREATMENT CAN OPTIMIZE MICROSTRUCTURE AND THE VALUE OF QUALITY FACTOR, WHICH INCREASES FROM 23 833.93 TO 47 584.00 AFTER 2 H OF HEAT TREATMENT AT 1 040 ℃. 相似文献

TRANSLATION OF BRAND NAMES IS A KIND OF INTERCULTURAL COMMUNICATION,WHICH INVOLVES REGIONAL CULTURES,CONSUMER PSYCHOLOGY ,AESTHETIC INTEREST AND SOME OTHER FACTORS.IT IS IMPORTANT TO ACHIEVE THE PRAGMATIC EQUIVALENCE IN THE BRAND NAME TRANSLATION. THIS PAPER FIRST BRIEFLY GOES OVER EQUIVALENT -EFFECT PRINCIPLES AND THE FEATURES OF BRAND AND BRAND NAMES.THEN IT ANALYSES THE CHARACTERISTICS OF ENGLISH AND CHINESE BRAND NAMES AND DISCUSSES FIVE APPROACHES TO THE TRANSLATION OF BRAND NAMES--LITERAL TRANSLATION; TRANSLITERATION; MIXED TRANSLATION; FLEXIBLE TRANSLATION AND ZERO TRANSLATION. 相似文献

MN2 DOPED ZN2SIO4 PHOSPHORS WERE SYNTHESIZED BY SOL-GEL METHOD, AND THE INFLUENCE OF ZINC SOURCE. MN2 DOPANT CONCENTRATION AND ANNEALING TEMPERATURE WERE INVESTIGATED. RESULTS SHOW THAT ZINC NITRATE BASED PRECURSOR WITH STRONG GREEN EMISSION INTENSITIES IS BETTER THAN ZINC ACETATE BASED PRECURSOR. THE INTENSITY OF GREEN LIGHT EMISSION REACHES A PEAK AT 254 NM WHEN THE MN2 DOPANT CONCENTRATION IS ABOUT 5%( MOLAR PERCENTAGE). STRUCTURAL DETAILS OF THE PHOSPHORS WERE EXAMINED THROUGH X-RAY DIFFRACTOMETRY. THERMOGRAVIMETRIC AND DIFFERENTIAL THERMAL ANALYSIS. THE RESULT INDICATES THAT THEY ARE BOTH RHOMBOHEDRAL STRUCTURES, WHICH REMAIN AMORPHOUS BELOW 700 ℃ AND CRYSTALLIZE COMPLETELY AROUND 1 000 ℃. THE LUMINESCENT PROPERTIES OF ZN:SIO4/MN2 PHOSPHORS WERE CHARACTERIZED BY EXCITATION AND EMISSION SPECTRA. 相似文献

AMERICAN EATING IS FUNNY. THEY EAT ALMOST EVERYTHING WITH A FORK, AND IT APPEARS THAT HOLDING A KNIFE IN ONE’S RIGHT HAND LONGER THAN A FEW SECONDS IS CONSIDERED TO BE AGAINST GOOD TABLE MANNERS. THE SYSTEM IS THAT IF IT IS ABSOLUTELY NECESSARY TO USE A KNIFE, PEOPLE TAKE THE FORK IN THEIR LEFT HAND, AND CUT OFF A PIECE OF MEAT OR WHATEVER IT IS IN THE NORMAL MANNER. THEN THEY… 相似文献
