检测

In this paper, an improved sensorless control strategy, which is based on the detection of zero crosspoints of back-EMF, is proposed. In this method, only one feed back signal is needed to sense terminal voltages and no motor neutral line is required. The phase shifter errors in traditional methods are eliminated.

正常人血清标本中分别加入一定比例的上述样品至S／Co比值在阈值并重复检测40次作重复性实验；气泡检出试验是在样品中加入50μL气体并重复检测20次；正常人血清连续系列稀释HBsAg强阳性标本并检测线性范围试验。

Survivin protein was detected in both nucleolus and cytoplasm in the four human cell lines, whose level is consistent with that of survivin mRNA.

应用RTPCR技术检测survivin mRNA在各细胞株的表达，用免疫组化法检测survivin 蛋白的表达，流式细胞仪检测细胞周期。

By default, GameObj's implementation of this method returns NULL (which means "do not test this object for collisions"). To detect object-to-object collision, we're going to override this behavior in our classes and return a collision structure for each object.

qaf在处理碰撞检测时，需要物体拥有这个方法，如果这个物体需要得到碰撞检测，就让这个函数返回其内部的碰撞检测结构体，否则可以返回NULL。

But this means can t carry continuous real-time on-line unosculant measurement, the working intensity of workers is great, and the speed is low.
