| 1. | So the likelihood function of the differential phase peaks can be formed as means to identify m - ary psk
于是可利用相位突变峰值的似然函数来识别信号为哪一种进制的psk信号。 |
| 2. | By reading the returning signals , the machines can identify the molecular structure of the materials it contains
通过读取引爆后返回的信号，机器可以识别信号里所包含物质的分子结构。 |
| 3. | It was reported that sz - 21 recognized the sequence ? 3 28 - 35 which is far away from the rod ligation site on gpiiia
这说明ntegfin与fn 、 coliv的结合部位不限于rgd序列，而具有不同的识别信号。 |
| 4. | Transport captain we ' re on a top secret mission and i ' m not transmitting a valid friendly id signal to the ground - based automatic defense systems
我们正在执行一次绝密的任务，而且我们不能发送有效的友军识别信号给地面的自动防空系统。 |
| 5. | It is indicated that hermitian wavelet has the ability to sensitively recognize the transient phase of signal through comparing the advantage and shortcoming of many kinds of methods used for singularity detection of signal
通过分析对比信号奇异性检测的各种方法的优点和不足，指出复数hermitian小波具备准确识别信号瞬时相位的能力。 |
| 6. | The microsystem is small and light , which can receive the identifying result in 100 meters , and can be used widely . it can be used in many kinds of situation to distinguish the targets , and have the ability of prewarning
该系统体积小、重量轻，可以在100米之内接收到识别信号，并且应用广泛，适用于多种场合下的目标识别，可以起到预警作用。 |
| 7. | Dendritic cells ( dc ) is the most powerful apc , which can markedly increase the antigen - presentation capacity by maximizing the pepitide - mhc complexes on the cell surface and upregulating the co - stimulatory ligands b7 - 1 and b7 - 2 , adhesion moleculees such as il - 12 that promote full activation of lymphocytes . full activation of antigen - specific t cells requires two signals - one signal coming via the tcr and the other signal through engagment of co - stimulatary molecules . t cells receiving one signal via their tcr are turned off by mhc ( major histocompatibility complex ) , via t cell cd28 binding to b7 on the dc induce tlymphokine and t cell proliferatiion
T细胞介导的细胞免疫在控制肿瘤生长方面发挥着重要作用， t细胞在发挥抗瘤效应(分泌细胞因子和直接杀伤)之前必须先经过活化，体内专职抗原提呈细胞( apc )细胞并使其活化，树突状细胞( dendriticcell , dc )为t细胞的激活提供双重信号， t细胞借助tcr识别由dcmhc分子递交的抗原肽后，通过tcr - cd3复合体传递抗原特异性识别信号(第一信号) ，以cd28为主的t细胞表面辅佐分子识别dc表面b7分子，传递非特异性协同刺激信号(第二信号) ，在机体抗肿瘤免疫应答中处于核心地位。 |
| 8. | The time - scale amplitude plot and phase plot based on hermitian wavelet transform are presented to singularity detection of signal . the corresponding relation relation between singularity and amplitude plot or phase plot is created . as successful application , fault of axletree damnify is found by means of this method
