We investigate a deterministic,conservative,undirected,and critical height sandpile model with dissipation of an energy at boundaries that can simulate avalanche dynamics.

通过研究如何用沙堆模型来描述电力系统的自组织临界性，提出了先建立各网省局等规模稍小电网的实时动态沙堆模型从而形成一个沙堆群的模型来模拟整个全国电网的设想。

Scandalously clad girl group and then by the cute but seriously off key little girl.

先是一群穿着暴露低俗的女子，然后是一个严重走音的小女孩。

Unfortunately they butchered the jasmine song, first with the scandalously clad girl group and then by the cute but seriously off key little girl.

很遗憾她们****了那首茉莉歌。先是一群穿着暴露低俗的女子，然后是一个严重走音的小女孩。

Methods Porcine bile duct and ureter were treated using detergent sodium dodecylsulphate and 1% Triton X-100 to prepare the acellular lumens matrix. The toxic effects of different concentrations of acellular lumens matrix extract were tested by MTT to assess the proliferation of human scarfskin fibroblasts. The cytotoxicity of the target biomaterial was graded according to the national standards. The growth manner of the human intrahepatic bile duct endothelial cells seeded on the acellular lumens matrix was studied after 20 d under scanning electron microscopy.

采用十二烷基磺酸钠、Triton X-100处理封闭群小香猪输尿管和胆管，获得去细胞管腔基质支架材料； MTT法检测基质支架材料的不同浓度浸提液对细胞增殖的影响，并按医用生物材料细胞毒性分级标准进行评级；在基质支架材料上种植人肝内胆管上皮细胞，于接种后20 d通过扫描电镜观察人肝内胆管上皮细胞在支架上的生长情况。

Looking southward late in the evening – toward the richest part of the Milky Way – you'll find a very small constellation, called Scutum the Shield.

傍晚晚些时候朝南看——银河中星星最为富饶的地带——你会看到一个非常小的星群——盾牌星座。

George Roy Hill, the director of such Oscar-winning hits as The Sting (1973) and Butch Cassidy and the Sundance Kid (1969), also helmed the comedy-drama Slap Shot (1977) with Paul Newman - noted as one of the raunchiest, most foul-mouthed, macho sports films ever made.

George Roy Hill是获奥斯卡奖的《骗中骗》和《虎豹小霸王》的导演，他也带头与Paul Newman合作了《火爆群龙》这部喜剧片，该片是部展示男子气概的运动电影，为以最为粗俗和最为污言秽语而引人注目的影片之一。

Fillmore, too, looked rather battered, even more disreputable than myself; his big slouch hat was on assways and his overcoat was still full of sawdust from the last joint we had been in.

祭坛上围在牧师身边的是一群小男孩，穿着打扮像上帝的安琪儿，他们唱男高音和女高音。

One wonders how so much can happen in so short a time to so small a group of people.

人们想知道如何这么多可能发生在如此短的时间内，以这么小的一群人。

Aiming at the disadvantage of conventional BP neural network, such as selecting parameter values by the empirical method, slow convergence speed and easy trap into local minimum points, this paper designs an improved BP neural network system. In order to improve the network convergence rate and reduce the training error, this paper optimizes the initial connecting weight value of neural network by the use of ant colony algorithm and trains artificial neural network by Levenberg-Marquardt algorithm.

针对常规BP神经网络参数的经验式取值方法以及收敛速度慢，容易陷入局部最小点等缺陷，设计了一种改进的神经网络系统，利用蚁群算法优化神经网络连接权初值，并采用LM算法对人工神经网络进行训练，提高了网络的收敛速度，降低了训练误差。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
