使向后

This section presents two kinds of characteristic schemes, one is the natural use of the usual backward Euler characteristic difference scheme ( [60] ) onto the triangular mesh, the other replaces the backward Euler's method by modified Euler formula to approximate the characteristic differential equation, so that the discretization for characteristic curve can get up to second order accuracy.

本节给出了两种三角形网格上的特征差分格式，第一种是通常的向后Euler型特征差分格式（[60]）在三角形网格上的自然运用，第二种采用§3.3、§3.4的离散思想，使用改进的Euler公式代替向后Euler公式来近似特征微分方程，使其对特征线的离散达到了二阶精度。

During a postoperative healing period following surgery, the anterior capsular remnant fuses to the posterior capsule of the bag by fibrosis (30) about haptics (36) on the implanted lens while the ciliary muscle is maintained in its relaxed state by a cycloplegic to prevent dislocation of the lens, and the lens is deflected rearwardly by the fibrosing anterior capsular remnant to a distant vision position against the elastic posterior capsule (24) of the bag in which the posterior capsule is stretched rearwardly.

在手术后的治愈期间，当睫状肌被睫状肌麻痹剂维持在其舒张状态时，植入晶状体上的触觉连接件（36）周围的纤维化（30）使前囊残边熔结到囊袋的后囊上，以防止晶状体错位。晶状体在纤维化的前囊残边作用下克服囊袋弹性后囊（24）而向后偏移到一个远视觉位置，在该位置上，后囊被向后拉伸。

The oil sewage disposed process is a complex disposal technique. The disposal process is more difficult for the change of PH Flux temperature of raw water and the other polluted quality. At present the disposed water by the system of oil of sewage is unstable and high cost. Now the method for the oil of sewage have physics chemistry physical chemistry and biology etc. In the every disposed method has its own specially, Basis of the oil sewage condition of power plant. The text use chemic method. Another word is method of Flocculation-deposition. Injecting Dosage into sewage. Making small suspends grain and the electrophorus colloid gather into bigger colloid and deposit. Separated it from water and purify the oil sewage. Make disposed oil water up to grade.

含油污水处理工艺是一个复杂的处理过程，在处理过程中由于受到原水浊度、PH值、配水流量、原水温度和其他水质污染等因素的影响，处理难度相当大，现时的含油污水处理系统普遍存在处理后的水质不稳定和处理成本高等问题，国内外含油污水处理采用的方法有物理法、化学法、物理化学法和生物法等，每种处理方法都有自己的特点，结合电厂含油污水的情况，本文主要采用化学法，具体来说是采用絮凝沉淀的方法，通过向废水中投加混凝剂，使细小的悬浮颗粒和带电胶体微粒聚集成较大颗粒而沉淀，使其与水分离，使含油污水得到净化，使处理后的废水各项指标达到排放标准。

The method comprises the following: a step of calibrating a camera, which is to utilize a Taylor series model to calibrate an omni-directional vision sensor so as to obtain internal parameters of the camera; a step of obtaining epipolar geometric relation, which comprises the steps of calculating an essential matrix between binocular omni-directional cameras and extracting the rotation and translation component of the cameras; a step of correcting an outer polar line, which is to correct the outer polar line of a shot omni-directional stereo image so as to allow a corrected polar quadratic curve to coincide with an image scan line; and a step of three-dimensional reconstruction, which is to carry out feature point matching to the corrected stereo image and calculate the three-dimensional coordinates of points according to matching results.

该方法的步骤包括：相机标定：利用泰勒级数模型对全向视觉传感器进行标定，得到相机内参；对极几何关系求取：包括计算双目全向相机之间的本质矩阵，并从中提取相机的旋转和平移分量；外极线校正：对所拍摄的全向立体图像对进行外极线校正，使校正后的极二次曲线与图像扫描线重合；三维重建：对校正后的立体图像对进行特征点匹配，根据匹配结果计算点的三维坐标。

This algorithm replace the traditional forword, and backword_ character-to-character conditional probabilities with forword_ and backword. character-to-syllable conditional probabilities so that the space of data-base may be greatly reduced and the efficiency of searching the best solutions is also improved.

摘要］ 本文论述了一种新的汉语音字转换的概率后处理算法，该算法用字相对于前后向拼音的条件概率代替常见的字相对于前后向汉字的条件概率，极大地压缩了数据空间，提高了查找效率，使概率后处理的实时应用更趋于现实。

Safety Belt Tension Furling Device: While a collision happens, if the driver uses a safety belt without tension furling device, the injury may happens by the collision on the instrument board or the steering wheel etc.; Safety belt tension device uses the gas generator in the safety belt tension furling device touched by the speed acceleration of collision, the gas expansibility generated will make the tension device rotate in the reverse direction, bringing the passengers back on the seats, protecting the passenger's security.

对于安全带预张紧卷收器：在发生碰撞事故时，若使用非张紧普通安全带，仍然有可能触及汽车方向盘和仪表板等部位而使乘员受伤；预紧式安全带利用撞车时的加速度触发安全带卷收器中的气体发生器，产生的气体膨胀力使卷收器反向旋转而收紧织带，将乘客向后拉向座椅，从而更可靠地保护乘客的人身安全
