查询词典 pi

According to the robust control H2 optimal performance specification, the practically desired diagonal elements of the system transfer matrix are suggested, and in view of the coupling action existing between the two closed loops, dynamic detuning factors are introduced to design the optimal double-loop controllers, and their executable PI/PID forms are derived using a mathematical rational approximation approach.

GISH analysis showed Triticale have 2 items chromosomes presented yellow and others chromosomes presented chrysoidine, because yellow chromosomes combined the Thinopyrum intermedium DNA, others chromosomes dye by PI. 4. Analysis of resistance gene: CH-9916 is the hybrid progenies of Octoploid tritielytrigia TAI-7045 X common wheat "Jinmai33".

GISH分析结果表明，小偃麦衍生系CH-9916的42条染色体中有2条外源染色体因结合有探针DNA而呈现出较强的黄色杂交信号，而没有结合上探针DNA的普通小麦染色体经过PI染色呈现出桔红色，初步推断小偃麦衍生系CH-9916为一个"小麦一中间偃麦草"的代换系。

Methods: Human leukemia cell line K562 was treated with different concentrations of WM. The proliferation of K562 cells was examined by MTT assay. DNA damage in K562 cells was examined by single cell gel electrophoresis assay, and apoptosis of K562 cells was detected by Annexin V-FITC/PI double staining. The expressions of total Akt, phosphorate Akt, and NF-κB p65 mRNA and protein were detected by RT-PCR and Western blotting, respectively.
