The high-resolution infrared spectrum of HCF 3 was studied in the ν 6 fundamental (near 500 cm 1) and in the 2 ν 6 overtones (near 1000 cm 1) regions. The present study reports on the analysis of the hot bands in the ν 6 region, as well as the first observation and assignment...
external resistor (R X ) and an external capacitor (C X ) control the timing for the circuit. Adjustment of R X and C X provides a wide range of output pulse widths from the Q and Q terminals. The time delay from trigger input to output transition (trigger propagation delay) and ...

其中筹备期40年,实际编撰期12年,删改定稿期42年。 2、《明史》真的被篡改得一个字都不能信了? 显然大师的这种话,不仅仅是在羞辱我的智商,也是在羞辱他粉丝的智商。 前面已经说了,万斯同版的《明史稿》,在康熙三十年就已经成书了;但是其后十几年,都是在万斯同在校订、删改,但是还没有完成,万斯同就不幸去...
This factor is traditionally lower than 1 and it reduces the fatigue limit value corresponding to the material in standard conditions. This coefficient may be obtained from literature graphs and it can be identified by means of two parameters: materials ultimate tensile strength and surface finish R...
