Results (1) 6 cases of Tuberous Sclerosis. Diffused subependymal nodular calcification lesions were found in all cases on unenhenced CT. 4 patients are 2 pairs of mother/child relationship. Both of the two mothers are found to suffer from renal angiomyolipoma.(2)1 case of neurofibromatosis showed abnormal spinal canal: scoliosis of thoracic and lumbar spine, concave change of vertebral posterior border. Bilateral renal hypogenesis was found in this patient. Diffused hyper-density lesions were found in kidney and fatty accumulation was found in back skin.(3)6 cases of Sturge-Weber syndrome. On unenhenced CT, curving and strip-shaped calcifications were found along the parietal and occipital gyrus.

His argument, known as the Hockney-Falco thesis, is that great artists of the past, such as Ingres, Van Eyck, and Caravaggio did not work freehand, but were guided by optical devices, specifically an arrangement using a concave mirror to project real images.

在那部著述中，他暗示过去最伟大的艺术家们，譬如安格尔、范·爱克，和卡拉瓦乔不是空手工作的，而是采用了光学设备的导引，特别是采用一面凹镜的一种安排，用以投影实像。

On the other hand,Raymond considered systemsgoverned by linear elliptic and parabolic differential equations with the integrand in costfunctional has to be concave in the state variable.

在那里，指标泛函中的被积函数关于状态变量必须是凹的。因而，那里所给的条件和Cesari条件是互不包含的。

It is considered that shaping the concave canopy structure by aitificial measures such as chemical control at intervals and belt-shape intercrop of tall and short cultivars can be an important way to further improve maize population yield.

研究认为，通过人为措施(如隔带化控和高矮品种带状间作)塑造凹形群体结构是进一步提高玉米群体生产力的重要途径。

Furthermore, it not only has better interpretability to the concave data sets than the existing depth functions, but also has a relative simple computation, which ensures its practicality.

相比现有数据深度而言，它对凹形结构的数据具有更好的深度解释。更为重要的是它的计算比较简单，从而保证了它的实用性。

Deep structure in the mantle concave or convex edge of mantle, Moho-discontinuity isobath or local turning control the regional metallogenic belt in distribution; major fault zones and their recombination region control the metallogenic zone; great fault depression, that is, overall depression in the context of uplift, that is, or local uplift in the background of overall fault depression, or the local stronger depression in the background of overall fault depression, all of these special structures are often the enriched areas of ore-forming elements and potential prospects.

深部构造，在幔凹或幔凸的边缘、莫霍面等深线密集或局部突出地段、扭曲端等控制区域成矿带的展布；大断裂带及其复合部位控制矿集区和大型矿床的产出；大断裂断陷构造，即隆中坳，或总体坳陷背景下的局部隆起，即坳中隆，或总体坳陷的背景下的局部更为强烈的坳陷，即坳中坳，所有这些特殊的构造部位，往往也是成矿元素的富集区和成矿远景区。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
