Significant digit error (± number for digital reads): If the reading is 100.0V and the digit is ± 2, the error is 0.2V. The minimum division on an analog scale is half (± 1/2 small division on an analog scale): If the minimum division on the scale is 1V, the error is 0.5V. A conservative error estimate is to take the sum of all types of errors. In summary, the reading error is ± 0.01, and FS is 0.07

(2) R0=ρ t2N1lNcAi1, where ρ t is the resistivity of the winding material at t ℃, and the resistivity of copper at 20 ℃ is ρ 20=1.75 × 10 − 8 Ω· m, with a temperature coefficient of α 20=0.0041 ∘ C − 1; N1 is the number of turns in series for each phase, Nc is the number of parallel conductors, l is the average half turn length of the winding, A is the cross-sectional area of the conductor, and a1 is the number of parallel branches. (2) For flat copper wire windings, due to the large cross-sectional area of the conductor, the AC loss of the flat copper wire winding...
3. PCIe (III) - PCIe protocol stack, transaction layer, and data link
Finally, the data link layer also supports Scaled Flow Control, which means that the number of credit limits can be a power of 2, so that larger credit limits can be managed. To help understand, lets give an example: Note: If viewing the original packet, when calculating, it should be noted that HdrFC and DataFC did not include it in bytes, so remember to do bit operations well. Firstly, the PCIe Endpoint will send the following three messages to the Switch for flow initialization: What are ventricular wall tension and ventricular wall stress? -Zhihu

3.4.2. Length and weight growth over the seawater period during the first period in the sea caves, both FTS and RAS groups showed similar body weight and length (Fig. 3). However, significant growth differences between the two groups were observed for 4 months after seawater transfer (Fig. 3,...
6. "Lucky Three Lives: Three Time Scales of Happiness Psychology") In this book, the selection of two words mainly follows the cited literature. In terms of evaluation details, emotions have two dimensions: arousal intensity (Activation) - positive and negative valence (Valence); Emotions are mainly evaluated using subjective well-being tools, focusing on frequency rather than intensity. Minor differences can be referred to: Ekkekakis, P. (2013). The measurement of affect, mood, and emotion: A guide for health-behavioral research. Cambridge ...7.
