The internal model control method is introduced based on the dynamic model of asynchronous motor in d-q reference frame. And the design of stator current controller is proposed in detail based on rotor flux oriented vector control.

在同步速d-q坐标系下异步感应电机动态模型和解耦控制原理的基础上引入了内模控制方法，详细设计了基于转子磁链定向和内模控制的定子电流调节器。

There is no perch , sealed cushion and orientation seat in the valve .The septa velum is only exercise in the routeway. So there couldn't be rustily, but more stability.

阀门没有阀杆、密封垫、定向座等，通道中运动的唯一部件就是隔膜，所以不存在锈蚀及抱死现象，具有更高的稳定性。

METHODS: MyoD cDNA fragments were extracted from plasmids pEMSV-MyoD with polymerase chain reaction, and PCR was used to clone the whole-length gene of MyoD. After adding CACC sequence at 5' end, MyoD gene was cloned by orient topology into transfer ventor, pENTR/D-TOPO. Objective gene was transferred into adenoviral expression vector DNA via pENTR/D-TOPO vector. The recombinant adenoviral vectors transfected into HEK293A cells by using lipofectamine were packaged and amplified.

从pEMSV-MyoD质粒上用聚合酶链反应法扩增出MyoD cDNA片段，再通过聚合酶链反应使MyoD基因加上CACC序列接头，经过定向拓扑克隆使目的基因连接到转移载体上，再通过LR酶促反应，将目的基因转移到腺病毒表达载体DNA上，获得MyoD基因重组的腺病毒DNA，用脂质体转染法转染HEK293A细胞，包装扩增出MyoD基因重组的腺病毒。

We think that the mechanism of directed forgetting should be rehearsal and retrieval by way of word method.

我们认为，在单字呈现的方式下，定向遗忘的机制应该是复述和提取抑制。

In addition, we have developed a simple and efficient computational method for design of zeolite frameworks with specified pore structures.

此外，我们还开发了一种简单、高效的计算机方法来定向设计具有指定孔道结构的分子筛骨架。

In this paper, two high temperature gradient directional solidification apparatus with liquid metal cooling and electron-beam floating zone melting were used.

本文采用LMC和电子束区熔两种高温度梯度定向凝固装置，研究合金成分及工艺参数对初生相析出行为的影响，优化了自生复合材料的制备工艺。

We show that degree-correlated scale-free networks are robust to random stimuli as well as the uncorrelated scale-free networks, while assortative scale-free networks are more sensitive to directed stimuli than uncorrelated networks.

我们的研究表明：度关联无标度网络过对随机刺激鲁棒，这一点与度无关网络一样；但是匹配无标度网络对定向刺激的敏感性比度无关网络更强。

Besides, the key biosynthetic genes were cloned and then expressed for directional breeding in molecular level .

Combination TGF-β3 with IGF-I can induce the MSCs capsulated in alginate microspheres to differentiate into chondrocytes, and chitosan-based scaffold is biocompatible with the induced chondrocytes.

转化生长因子β3和胰岛素样生长因子Ⅰ能诱导藻酸钠微球中的骨髓间充质干细胞定向分化成软骨细胞，并与壳聚糖复合支架表现出良好的组织相容性。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
