中间相

The non-continuously moving state lies on the vehicle's structural characteristic. This air-cushion vehicle has two platforms, which are connected by two hydraulic cylinders. When it moves, one platform is fixed on ground as the base platform, and takes the other one as moving platform, then the vehicle can go forward by alternate movement of these two platforms. So the push-pull air-cushion vehicle is a self-propelled vehicle.

它的非连续运动形态取决于其结构特点，该气垫车由两个对称的子平台组成，中间通过液压油缸相铰接，运动时总是固定其中一个平台作为基础平台，而将另一个平台作为运动平台，基础平台通过液压缸推出或拉进运动平台交替动作，实现运动，因此推拉式气垫车是一种自走式气垫车。

Therefore the dispersion curves obtained in the field are primarily consisted of the first mode. For a heterogeneous elastic solid consisting of three homogeneous layers whose interlayer has low velocity, the phase velocity V〓 of the first mode will also close up to the Rayleigh wave velocity of the bottom layer when frequency f→OHz, but V〓 of the first mode will close up to the shear wave velocity of the interlayer when f→∞, and there is a cut-off frequency at high frequency region for the first mode and V〓 close up to the compressional velocity of interlayer when interlayer is liquid.

当三层固体介质中存在软夹层时，若f→OHz，则其基阶模式的相速度V〓→V〓（V〓为最底层介质的瑞利波速度）；若f→∞，其基阶模式V〓→V〓（V〓为中间层介质的横波速度）；若三层介质中存在液体夹层，当f→OHz时，基阶模式V〓→V〓，而基阶模式在高频段存在一个截止频率，截止频率处的瑞利波速度V〓→V〓；由此可判定，野外实测的相速度频散曲线不仅有基阶导波模式，同时还应有高阶导波模式波的存在，接收信号中存在模式间的跳跃，因此频散曲线会产生"之"字形现象。

A reversed-phase high performance liquid chromatographic method was used to detect resorcinol and m-chlorophenol .

采用高效液相色谱法测定间二氯苯水解产物中间苯二酚、间氯苯酚的含量，以C18为固定相，V∶V=80∶20为流动相，检测波长为273 nm。

The PS-b-PNIPAM-b-PDMA and PS-b-PDMA-b- PNIPAM triblock copolymers can self-assemble into PS-core micelles, which possess a three layer \'onion-like\' structure, with PDMA and PNIPAM blocks forming the inner layers or outer coronas. Using above measurements, we can concluded that PS-b-PNIPAM-b-PDMA triblock copolymer micelles have the double phase transition behavior, while PS-b-PDMA-b-PNIPAM have only one phase transition behavior.2. We synthesized poly(ethylene glycol-b-methacrylic acid)diblock copolymers with three different polymerization degree of PMAA blocks.

但是对于PS-b-PDMA-b-PNIPAM胶束，由于中间亲水嵌段的作用，使PNIPAM的相转变温度提高，且PDMA由于靠近PS内核以及随着外壳PNIPAM的水溶性变差其相转变点降低，因此我们只能看到一个转变过程。2、通过原子转移自由基聚合，我们合成了三种不同PtBMA长度的PEG-b-PtBMA二嵌段聚合物，将叔丁基水解后得到了三种PEG-b-PMAA二嵌段聚合物。
