The kinase catalytic domain is 264 amino acids in length and contains all of 11 conserved subdomains and 15 invariant amino acid residues essential fo r eukaryotic serine / threonine protein kinases
激酶區長264個氨基酸殘基，具有所有11個保守的亞結構域和15個對于真核生物絲氨酸蘇氨酸蛋白激酶所必需的保守的氨基酸殘基。 -
Hence this method can improve accuracy and efficiency of the calculation. c. based on these work upwards, an adaptively wavelet precise time - invariant integration method was proposed in this paper. in this method, an adaptive multilevel interpolation wavelet collocation method for partial difference equations ( pdes ) was conducted, in which the time complexity is less than oleg v ' s method, and then the adaptive precise integration method was combined with, so that in this method the adaptively discretes both in time domain and physical domain were realized
該方法將外推法引入求解結構動力方程的精細時程積分法中，從而使該方法在求解非線性動力方程中可以自適應選取時間步長；需要指出的是，由於考慮了矩陣指數精細演算法和外推法演算法在時間離散方法上的一致性，在外推過程中，計算工作量基本沒有增加；因此，兩種方法的結合有效提高了演算法的效率和精度。 -
The current control approaches are based on frequency domain methods such as pid control which assumes linear time invariant system dynamics. the advantages of these approaches are simplicity and ease of stability and robustness analysis. however, the decrease in performanc e and poor efficiency translates to additional payload and cannot meet the demand of current spacecraft control
當前飛行器主要的控制方法是基於近似時不變線性系統的頻域分析法（如pid控制） ，這種方法的優點是簡單且易於穩定性和魯棒性分析，但它所達到的低性能和低效率卻轉化成了飛行器控制過程的附加載荷，還遠不夠滿足當前飛行器控制的要求。 -
Therefore, based on the ann correlation signal post - processing technique, we designed a kind of sdf performed in spatial domain, and a two - step recognition technique was introduced to perform real - time distortion - invariant recognition by combining frequency domain filtering of sdf with spatial domain filtering of sdf
為此，本文在ann相關信號后處理技術的基礎上引入了二次識別技術，設計製作了一種空域執行的sdf濾波器，採用頻域sdf濾波與空域sdf濾波相結合的方法，對目標進行實時畸變不變識別。 -
Note that in fractal encoding, each range block is to compare with domain blocks after some grey - level affine map. hence we first put forward a kind of image quadrature invariant of affine maps above, which can be thought of a generalization of mario feature
由於在分形編碼時值域塊實際上是與經過灰度仿射變換之後的定義域塊進行比較，因此我們首先提出了一種在灰度仿射變換下保持不變的圖像矩不變量，它可看作是mario特徵的推廣。 -
