Abstract: A method and kit for the immunotyping of T lymphocyte development subgroups. The method for the immunotyping of T lymphocyte development subgroups comprises: taking antibodies with different fluorescence labels, mixing same with a to-be-detected sample, performing incubating, and then performing detection by means of flow cytometry to obtain detection data, wherein the antibodies comprise: an anti-CD45 antibody, an anti-CD3 antibody, an anti-CD4 antibody, an anti-CD8 antibody, an anti-CD25 antibody, an anti-CD127 antibody, an anti-CD45RO antibody, an anti-CD28 antibody, an anti-CD197 antibody and an anti-CD95 antibody. According to the present invention, more comprehensive immunotyping of T lymphocyte development subgroups is achieved, few to-be-detected samples are required, operation is easy, the required time is shorted, and the accuracy is high.

Abstract: A differential power amplifier includes an input matching network, a first-stage amplification circuit, a first inter-stage matching network, a second-stage amplification circuit, a second inter-stage matching network, a third-stage amplification circuit, and an output matching network. The first-stage amplification circuit and the second-stage amplification circuit are single-ended input single-ended output circuits. The third-stage amplification circuit is a dual input dual output circuit. The second inter-stage matching network includes a first transformer T1, a first capacitor C1, a second capacitor C2, a first inductor L1, and a second inductor L2. The output matching network includes a second transformer T2. The inter-stage matching networks and the output matching network are realized by the first transformer T1 and the second transformer T2, which reduces an inter-stage matching difficulty, optimizes input return loss and gain, and improves output power.

Abstract: Disclosed are a vehicle power transmission system and a vehicle power system. The vehicle power transmission system includes two motor output shafts, two power output shafts and two transmission mechanisms respectively connected between the two motor output shafts and the two power output shafts correspondingly. Each transmission mechanism includes a motor output gear, a power output gear and a middle transmission gear structure.
