We extend the second order elastic tensor of Husdon's and turn it to a matrix which makes the calculation of second order perturbation much more concise. Then the azimuthally phase and group velocity formulas of plane wave propagation in horizontal plane are deduced according to Christoffel equation, and the azimuthally dependent velocities in dry and water saturated cracked medium are calculated.

而后，根据Christoffel方程推导了由各向同性背景介质中含两组非正交的垂直裂隙而形成的等效单斜各向异性介质中，在水平面内随方位变化的相速度和群速度的计算公式，并对干裂隙和饱和流体填充裂隙介质两种具体情况进行了计算。

In Chapter Six,we translate the equation of the iterative step of nonsmooth Newton-type method for nonlinear SDP into the conversional linear equations by the tensor technique. By using the equivalency conditions in Chapter Five, we establish the local convergence of this method.

在第六章中，我们通过张量技术把非线性半定规划问题的非光滑牛顿型法迭代步方程转化为一般的线性方程组，并利用第五章中的等价性结论分析了这种方法的局部二次收敛性。

Diffusion tensor imaging is a kind of new technique after diffusion weighted imaging.DTI can reflect anisotropy hydrone molecular diffusion features of damaged myeloid tissue through measuring apparent diffusion coefficient and fractional anisotropy.Accordingly,we can make more precise and allround estimate about spinal compression on microscopic scale.

磁共振扩散张量成像是继扩散加权成像后发展起来的一种新技术，它通过测量表观扩散系数及部分各向异性值来反映损伤脊髓组织的各向异性水分子扩散特征，从而在微观水平对脊髓压迫症做出更精确和全面的评价。

So, give it a kiss, and then roll the crap out of your quads, hips, glute medius, tensor fascia latae, and lats.

所以让我们更加勤奋的练习大腿、臀部、髋部和背阔肌吧。

The meridionally accelerated axial-flow fans including meridian acceleration rotor, vaneless diffuser and volute was numerically simulated in the whole flow passage by Reynolds time-averaged N-S equations with tensor and k-ε turbulence model.

采用三维雷诺时均N-S方程和标准k-ε湍流模型，对包含叶轮、无叶扩压器与轴向蜗壳于一体的子午加速风机进行了整机全流道的数值模拟。

Objective To investigate the pathogenesis of the abnormal diffusion in the white matter tracts in patients with neuromyelitis optica using diffusion tensor imaging.

在视神经脊髓炎(neuromyelitis optica，NMO)患者，脑白质纤维束的扩散异常已有报道，但其分布模式及发生机制尚不清楚[1]。

Objective To investigate the presence of occult brain tissue damage in patients with relapsing neuromyelitis opticaand its possible mechanism by using diffusion tensor imaging.

目的利用扩散张量成像探讨复发性视神经脊髓炎患者是否存在隐匿性脑组织损伤及其发生机制。

The algorithm is based on the tensor expression of the second-order nondegenerate perturbation formulae of Bloch wave method of many-beam dynamically diffraction theory.

这些数据以被收录到新版《X-射线国际晶体学表》的C卷中。完善了高能电子衍射的非简并微扰理论的张量表述。

The findings also reaffirm the first mention of the connection between the tensor force and carbon-14 decay, made by Israeli physicist Igal Talmi in 1954, notes physicist Larry Zamick of Rutgers University in Piscataway , New Jersey.

新泽西州拉格斯大学的物理学家拉里·赞米克指出，这个发现再次证实了以色列物理学家艾格尔·坦尔米1954年首次提出的有关张量力跟碳14衰变之间的关系。
