稀疏

Finland's glacial, yet pastoral winters form the perfect backdrop for these moody, electro-jazz recordings, from the sparse electronic hum of "Intro" to the sultry, cinematic horns and strings sweeping across "The Way I Play." Koivisto's late-night, come-fuck-me coos on the sexy, soulful groover "Quest For Love" will get anyone laid and will certainly do in a pinch if you've lost your "Barry White's Greatest Hits" CD.

芬兰的冰川，然而牧冬天穆迪这些形式的完美背景、电爵士乐唱片，由稀疏电子嗡"内含"的闷热、犀角、弦乐电影席卷"我扮演"罗的深夜，来到-他妈的--我的库斯性感，顾盼开槽"追求爱情"打下一定会有人做了捏若你失去你的"白色巴里的最大点击"光盘。

Gynoecium in female flowers 1.5-2 mm, in male flowers 0.2-0.5 mm; ovary sparsely hirsutulous.

Gynoecium在雌花1.5-2毫米，在雄花0.2-0.5毫米；子房毛发稀疏。

This is not an issue in heavily populated areas with high cell density, but may become an issue in sparsely populated/rural areas.

这在和高的细胞密度的人口稠密的区域中不是一个议题，但是可能在稀疏地居住/乡下的区域变成一个议题。

In the method, the symmetric positive semidefinite matrices are updated to approximate the Hessian matrices of the elemental objective functions and their sum to approximate the Hessian matrix of the objective function.

算法用对称半正定矩阵作为元素目标函数的Hessian阵的近似，使得其和仍然保持目标函数的Hessian阵的某种稀疏性。

Recently, it is a hot research at home and abroad in portioning groups of the matrix to iteration which is based on the structure of the Hessian.

近年来，结合稀疏Hesse阵的结构，按照分划组的思想将矩阵列分划进行迭代是国内外研究的一个热点。

A strict proof of the hyperbolicity of the multi-class LWR (LighthillWhitham-Richards) traffic flow model, as well as the descriptions on those nonlinear waves characterized in the traffic flow problems were given. They were mainly about the monotonicity of densities across shocks and in rarefactions.

证明了交通流多等级LWR(Lighthill-Whitham-Richards)模型的双曲性质，并根据交通流的特征给出关于其非线性波的描述，主要包括车流通过激波和稀疏波时密度和速度的单调性变化。

The usual travel time tomography method is based on geometrical ray theory,however,it assumes that the seismic wave has very high frequency,which often makes the tomographic inversion have ill posed problem because of the sparse ray distribution in the model space and finally affects the reliability and resolution of the tomographic results.

基于几何射线理论的旅行时层析方法假设地震波频率足够高，这样往往由于射线存模型空间的稀疏分布，使层析反演问题具有严重的不适定性，从而极大地影响层析成像结果的可靠性和分辨率。

The PSD-PCG algorithm is effective to sovle ill-conditioned linear system of equations whose coefficient matrix is symmetric and positive definite and sparse.

本章提出的PSD—PCG法是解对称正定的稀疏病态线性方程组的有效算法。

In the third chapter, a measure of frequency estimation based on signal sparse decomposition is introduced.

在第三章中，介绍了基于信号稀疏分解的频率估计方法。

Trees, monoecious or dioecious; indumentum of simple or T-shaped hairs, often sparse.

乔木，雌雄同株或异株；具单毛或丁字毛，通常稀疏。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
