vector: n. 1.【數(shù)學(xué)】向量,矢量,動(dòng)徑。 2.【航空】飛機(jī)航線;航向指示。 3.【天文學(xué)】幅,矢徑。 4.【生物學(xué)】帶菌者[體],傳病媒介。 vt. 【航空】(對(duì)飛行中的飛機(jī))指示航向。 vi. 【航空】電(磁)波導(dǎo)航。
prior to the vector construction, the availability of gene replacement was extensively tested in streptomyces . sp . fr-008 在載體構(gòu)建之前,我們先在鏈霉菌fr-008中驗(yàn)證了基因置換方法的可行性。
the jacobian matrix of the 6-prrs parallel robot has been computed by two methods . one is differential coefficient based on symbol operation, the other is vector construction 對(duì)于6-prrs并聯(lián)機(jī)器人的雅可比矩陣,分別使用了基于符號(hào)運(yùn)算的微分構(gòu)造法和矢量構(gòu)造法進(jìn)行求解,并驗(yàn)證了兩種方法的正確性。
to interpolate the given ship offset data, the ship-hull surface is represented successfully by nurbs . the boundary conditions computation and knots vector construction are detailed in nurbs curve and surface interpolation 本文根據(jù)船體型值表的數(shù)據(jù),用nurbs曲面來描述完整船體曲面,對(duì)插值曲面邊界條件構(gòu)造及節(jié)點(diǎn)矢量計(jì)算進(jìn)行了研究,實(shí)現(xiàn)了船體曲線曲面的nurbs表達(dá)。
