The so-called AT-algebras are inductive limits of finite direct sums of matrices over the extension algeras of circle algebra by K, where K is the C~*— algebra of all compact operators on a separable infinite dimensional Hilbert space.

若V_*与V_*同构，且保持单位元等价类；T与T仿射同胚，且同构映射与同胚映射相容，则存在E与E′的同构导出上述同构和同胚，所谓AT-代数即为圆代数通过κ的本质酉扩张的矩阵代数的有限直和的归纳极限，这里κ为可分的无限维复Hilbert空间上的紧算子全体，不变量中的V*为三变元Abel半群，T为迹态空间，[1]为单位元所在的Murray-von Neumann等价类，r_E为连接映射。

The L929 represented the unremarkable colonies, low speed of growth and differentiation, reduced density as well as shrinking of synapsis along with time of the electromagnetic fields of HVTL exposure.

高压输电线电磁辐射暴露时间越长的L929细胞，分化速度越慢，而且个别细胞变小、变圆，单独生长，单位面积内细胞数、集落数显著减少。

The westbound along the revitalization and gradually on the flat 500 meters beyond the scope of the round, so it is not very familiar with.

沿着振兴路西行，逐渐就超出单位500米圆范围了，所以就不是很熟悉了。

Conventionally, computing the discrete Fourier transform that is equivalent to sampling of the z transform of the input sequence at equally spaced angles around the unit circle.

在以往，我们计算离算傅立叶转换相当於在z平面的单位圆上均匀的取样，然而，在某些应用上，非均匀的取样会更有效率。

A plurality of magnets and condenser units are also mounted on the inside of a circular nonmagnetic enclosure in a circumferentially spaced direction and outside an interior pipe which is coaxial with the enclosure.

磁铁的复数和冷凝器单位并且登上在圆无磁性的封入物的里面在周围地间隔的方向和外部是同轴的以封入物的内部管子。

We have investigated the conformational features of four short peptide fragments of Staphylococcal nuclease by homonuclear two-dimensional NMR and circular dichroism with a view to examining the early events in the folding process of SNase.

中文题名金黄色葡萄球菌核酸酶折叠起始位点：N-末端短肽段的NMR研究副题名外文题名 Folding initiation sites of staphylococcal nuclease：exploring the solution conformation of N-terminal fragments by nuclear magnetic resonance 论文作者戴继勋导师王金凤研究员学科专业分子生物学研究领域\研究方向学位级别博士学位授予单位中国科学院生物物理研究所学位授予日期2001 论文页码总数68页关键词金黄色葡萄球菌核酸酶蛋白质折叠核磁共振馆藏号BSLW /2001 /Q71 /89 本论文工作用四个金黄色葡萄球菌核酸酶N-末端短片段作为新生肽链折叠的模型，用同核二维核磁共振谱和远紫外圆二色谱研究了它们的溶液构象特征。

The chloroplast of the mesophyllous cells in the white part of the green-white leaf of PM3 were dissolving or had dissolved.

观察其叶片表面结构和叶肉细胞超微结构，结果表明：3个突变株系的叶片气孔密度增大，气孔面积减少，单位视野中气孔所占面积比则变化不大；叶肉细胞中叶绿体体积增大，形状变圆并移向细胞中央；PM3株系白绿相间叶片的白色部分，其叶肉细胞中叶绿体多数正在或已经消解，结构不完整。

Transmitted torque was composed of magnetic force torque and viscosity torque. Maximal diameter of the actuator disk was key size to improving torque. Torque by unit moment of inertia decreases and viscous power loss increases with maximal diameter increasing.

机构传递的力矩由磁致力矩与粘性力矩构成，圆盘外径是提高传递力矩的关键尺寸；外径的增大会减少单位转动惯量所传递的力矩，增大粘性功率损失。

With the increase of vibration frequency, the variation process of Jacobi matrix eigenvalue was calculated. According to the position of eigenvalue crossing the unit circle in the complex plane, the stability of fixed point of the map was discussed and the route from periodic motion to chaos via period-doubling bifurcation was received.

以振动频率为控制参数，计算得到映射Jacobi矩阵特征值的变化曲线，根据其穿越复平面单位圆的位置，分析了映射不动点的稳定性，获得了碰撞运动通过典型的倍周期分岔通向混沌的过程。

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。
