Compared with standard Crank-Nicholsonscheme in the same computational time and resource, the method has two characteristics: small truncation error of in the transverse direction and high accuracy. It is a useful tool for designing optical waveguide devices.

与标准格式的有限差分光束传播法相比，该算法在几乎不增加计算时间和计算机内存资源的情况下，结合了道(来源：122eA22BC论文网www.abclunwen.com)格拉斯格式的有限差分光束传播法截断误差小和宽角多步法所具有较高精度的优点，是光波导器件理想的数值模拟工具。

Devise hand positions and motions that automatically increase speed; this topic is one of the major contributions of this book, and will be treated topic by topic later on as it is too big to be covered here; it involves such specific skills such as thumb over method, glissando motion, relaxation, flat finger positions, arm and wrist motions, etc., and the use of "post practice improvement".

设计最佳的手型与动作，来精确地控制相角（译注：即手指落下的时间差），这个位置也让你的手可以流畅地连接到下一个平行音组。如果在数分钟内都没有多大进步，那你或许有甚么地方做错了–这时候就要想另外的方法。

Summer and autumn festival is the largest fish in the river, we are often dug from the ground a few earthworms for bait, discontented adults to seek out street 2 cents to buy a fish hook, with wire connection to come back, and re-election from home a slender bamboo pole, a simple way on the cause of the rod.

夏、秋季节是河里鱼儿最多的时候，我们常常是从地里挖几条蚯蚓作诱饵，怏求大人到街道掏2角钱买个鱼钩，回来用线连接好，再从家里选个细长的竹竿，这样一副简陋的的鱼竿就做成了。

叶5，不完全膨大的在花期；叶柄5.5-15厘米，具厚具长柔毛毛；叶片差不多肾形，圆形卵形，或具5个角， 2.5-7 * 4.5-11厘米，多少具3小叶，背面具白色的毛，正面无毛，基部宽心形；侧生小叶近无柄，不均匀2裂；中心的小叶近无柄或具一1-4毫米小叶柄，3深裂，裂片全缘的或多裂，末级的裂片三角形到狭线形和2-3.5毫米宽。

In order to design lighter and faster hydraulic excavator, a rigid-flexible hybrid modeling method based on rigid multi-body dynamics and finite element method was put forward to study the dynamic characteristic of hydraulic excavator in its whole working cycle. The working equipment with characteristic of time-varying structure was taken as research object, and radial acceleration was computed as tags of key load.

为适应液压挖掘机高速、轻量化的要求，以具有时变固频特性的液压挖掘机工作装置为研究对象，提出了以角加速度判断时变结构的关键工况，利用刚性多体动力学和有限元方法对液压挖掘机在整个作业循环中的动力学特性进行建模和分析。

Here we present a case of 21 year-old male who suffered from recurrent swelling in left side of mandible which had received surgery for ossifying fibroma in another hospital when he was 19 years old. Obvious facial asymmetry was noted but no sensory dysfunctions were detected. The lesion showed well-demarcated, multilocular radiolucency but radiopacity centrally. We applied segmental resection via extra-oral approach and reconstructed with anterior iliac crest bone graft. After removal of MMF in six week, the wound healed well and joint function was good without malocclusion. After follow-up of one year, no recurrences were noted.

本病例为－21岁之男性，在19岁时因为左下颚骨角区肿大在某医院接受外科手术处理，术后病理报告为骨化纤维瘤，因为复发的肿胀而来本院寻求治疗，临床检查并无疼痛及下唇区感觉异常的问题，放射线影像为周界清晰，多腔室放射透过性合并中央放射不透过性之不规则小块，手术方式为从口外颚下切线，做下颚骨片段式切除，并以肠骨脊海绵骨移植修补骨缺损加以颚间固定六周，术后伤口恢复及愈合良好，颚骨关系稳定无咬合异常的情况，无张口受限的问题。

Detect drive way too much space is a fixed power input shaft and output shaft rotation shaking, in the case of the transmission structure of conventional design and manufacture of machine tools, the transmission output shaft angle space at more than ten degrees to the dozens of degrees Transmission gap caused by too large spiral screw groove surface then there is obvious marks, thus affecting the machining accuracy of the screw.

检测驱动方式太多空间是一个固定的动力输入轴与输出轴旋转摇晃在常规情况下传动结构设计和制造的机床，传动输出轴角空间超过度到10度的数十个输电差距过大造成的螺旋槽螺旋面则有明显的标志，从而影响了螺丝加工精度。

But there's more. Google Bruce Ivins' name and you'll find a lot of discussion about an oil called squalene.

但是更多的是，在谷歌上搜索布鲁斯艾文斯的名字，你会发现有很多关于叫做角鲨烯的石油的讨论。

In the 1960s, drilling for oil and gas was investigated throughout the Great Barrier Reef,[56][57] by seismic and magnetic methods in the Torres Strait, along "the eastern seaboard of Cape York to Princess Charlotte Bay" and along the coast from Cooktown to Fraser Island. In the late 1960s, more exploratory wells were drilled near Wreck Island in the Capricorn Channel, and near Darnley Island in the Torres Strait, but "all results were dry".

上世纪60年代，人们开始在托雷斯海峡，沿约克角半岛东部到夏洛克公主湾，从库克顿海岸到弗雷泽岛，用地震仪器定向和磁偏角的方法来探测大堡礁可能存在的石油和天然气。60年代末期，摩羯海峡的沉船岛以及托雷斯海峡的达恩利岛附近，新建了更多的勘探油井，但仍然一无所获。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
