positive cam 中文意思是什麼
positive cam
解釋
確動凸輪-
As both the meshing point and ball ' s center are on the given cylinder, a general method for developing the cam ' s profile is studied. it is proved that the profile of positive and negative transmission is unique if the face gear, the difference between face tooth number and ball number and the diameter of ball are the same. the concrete expression of meshing cam on given spatial cycloid profile, and the characteristics of the profiles are discussed
論文的主要工作包括： 1 、根據嚙合點和鋼球中心軌跡均在同一圓柱面上的特點，研究了給定端齒齒廓條件下求解凸輪齒廓的一般方法；論證了在給定端齒、齒差數和鋼球直徑相同的條件下，正負齒差嚙合齒廓的唯一性；討論了端齒為球面擺線時，凸輪齒廓的具體表達式，並研究了該齒廓的性質。 -
We also found an angiostatin - like protein and the detection of its activity on chick embryo chorioallantoic membrane model ( cam ) shows a sign of inhibition of the positive effect of lung cancer cell culture supernatant on cam. conclusion : development of proteomics brings out highly efficient approach for apr research, which overcomes the drawbacks of traditional methods including low efficiency and difficulty in detecting new apr - related proteins and the intrinsic false positive reaction of recently developed ssh technology
結論：蛋白質組學為apr領域帶來高效率高通量的研究方法，改變了傳統的elisa方法需要事先確定靶蛋白的低效的，而且難以發現新蛋白的狀況，也克服了suppressionsubtractivehybridizaition （ ssh ）技術固有的假陽性，實現了對app候選蛋白快速的鑒定。 -
