  1. The longer the period, the brighter the star is. thus, by measuring the period of a cepheid variable, we know its absolute magnitude, hence, we can tell how far it is away by comparing with its apparent magnitude

    所以,只要知道某一造父變星的周期,我們便可得知它的絕對星等,只要和它的視星等作比較,便可以求得它和我們的距離。
  2. Using this method to dispose interference of output signal of sensing elements, the interference caused by fixed position heat source of constant and adagio variable temperature can be effectively eliminated in exterior

    用這種方法對敏感元件的輸出信號進行處理可以十分有效地消除位置固定(或移動速度很慢)的熱源所產生的干擾。
  3. In view of this situation and the characteristic of qualitative variable as well as quantitative variable of the geological factors affecting coal seam affusion, put forward the application of numerical theory on the basis of optimization study of orthogonal design to confirm the optimal combination of the technical parameters of coal seam affusion when geological factors is in precarious state and then proceed optimization study with instances

    針對這種情況及影響煤層注水的地質因素既有定性變量,又有定量變量的特徵,本文在利用正交設計優化研究的基礎上,提出利用數量化理論確定地質因素為不穩定狀態下的煤層注水工藝參數的最優組合,並結合實例進行了優化研究。
  4. When measuring the magneto performance parameter , we find that the instrument which use to measure voltage and current is still the simple voltmeter and amperemeter in the national standard , and the form of wave that we observed is anomaly. based on the measure principles, it obviously ca n ' t be used to do quantitative analysis ; because the discharge process of ignition system is quite complex, accompanies with very strong electromagnetism interference, and the ignition current and voltage are variable , it make the measure of ignition energy become a difficult thing of ignition system performance detection

    在磁電機常規測量時,發現在國家標準中用於測量電壓、電流的儀器仍然是普通的電壓、電流表,而觀測到的波形多為不規則的形狀,根據測量原理,顯然不能用其來做定量的分析;由於點火系統的放電過程比較復雜,伴隨著很強的電磁干擾,點火電流、點火電壓都是變量,使得點火能量的測量成為點火系統性能測試的一個難點。
  5. The operand is an 8 - bit integer containing the ordinal of a local variable or an argumenta

    該操作數為包含局部變量或參數的序號的8位整數。
