Many large highspeed and long runout landslides could fly in the air at the short-range stage. It is necessary to consider the areodynamics effect and ground effect at the short-range stage of landslide where it starts to fly. However, it is difficult to solve the differential equation with analytical solutions.

许多大型高速远程滑坡在近程活动阶段呈现凌空飞行运动，其飞行过程必须考虑空气动力学效应和地面效应，但是直接求解高速滑体凌空飞行运动的偏微分方程是困难的。

But, in practice, these equations are too difficult to solve analytically.

但是，在实践中，这些方程是太困难，要解决解析。

And it is verified by experiment results which are obtained from the analyzer Hannover-XII made in Germany.

The patient is a victim of recurrent renal stone and urethral stone. Due to SOB, dysuria, anasarca, pain, and irritable mood. She was admitted to ICU and was diagnosed as acute renal failure. We gather the relative clinical information by interviewing, communication and observation, and evaluate the behavior and stimulate factors of her physiological function ,self- recognition, role function, inter-dependence.

After anatomization to those students who lack of interest and motivation to English study and lead to lower scores during their study process, you can find there becomes a vicious circle of difficulties, beyond interest, not good marks, out of interest, low scores and once more again and again.

仔细分析一下那些对英语学习缺乏兴趣，缺乏学习动力因而成绩很差的学生，你就会发现，他们在困难→不感兴趣→成绩差→更不感兴趣→成绩更差的轨道上形成了恶性循环。

Sum up as follows now. This group uses 1 clinical data ancon vein is pressed determine heart function of the patient 44, male 24, female 20; age 46 years old of ~79 year old, average 56 years old of; classification by function of new York heart, heart failure Ⅲ spends 6,Ⅱ spends 23,Ⅰ spends 15; right heart failure 31, complete heart failure heart disease of sex of source of 13; lung 14, hypertensive heart disease 8, coronary heart disease 5 (among them acute cardiac muscle straightens dead 2), outspread sex cardiac muscle is ill 7, rheumatism sex heart disease 4, hypertensive heart disease is amalgamative coronary heart disease 3, be short of disease of cardiac muscle of courage and uprightness 2, congenital heart disease 1. 2 detect 2.1 equipment treat the method dish 1, l measure press glass to be in charge of 1 (long 30cm, internal diameter 4mm), also can use measure a head to press a canal to replace, 10mL injector 1, 12500U heparin fluid 1. 2.2 operations patient is taken smooth lie, make be exhibited outside the upper arm show ° of 45 °~60 with trunk, and difficulty breathes like the patient in same horizontal; with right atrium, desirable lie partly, arm height is equivalent to the 2nd costal region.

现总结如下。1临床资料本组采用肘静脉压测定病人的心功能44例，男24例，女20例；年龄46岁~79岁，平均56岁；按纽约心功能分级，心力衰竭Ⅲ度6例，Ⅱ度23例，Ⅰ度15例；右心力衰竭31例，全心力衰竭13例；肺源性心脏病14例，高血压心脏病8例，冠心病5例(其中急性心肌梗死2例)，扩张性心肌病7例，风湿性心脏病4例，高血压心脏病合并冠心病3例，缺血性心肌病2例，先天性心脏病1例。2检测方法2.1设备治疗盘1个，L型测压玻璃管1个(长30cm，内径4mm)，也可以用测脑压管代替，10mL注射器1具，12500U肝素液1支。2.2操作病人取平卧位，使上臂外展和躯干呈45°~60°，且和右心房在同一水平面；如病人呼吸困难，可取半卧位，手臂高度相当于第2肋间。

We present a case of a 53-year-old female who presented with progressive dyspnea and was diagnosed as bronchiolitis obliterans associated with consumption of Sauropus androgynus.

我们在这里提出一个病例报告，这是一位53岁女性，临床上出现渐进性呼吸困难，经诊断为因食用守宫木造成阻塞性细支气管炎。

The contact angle of glycerol on the fiber plasma treated can decrease from 69°to 21°, i.e. reduction by 70%.

它的不吸湿性不仅使染色困难，而且大大地限制了其在服装面料上的应用。

The gyro gunsight at last solved the most difficult problem faced by pilots and air gunners, that of finding the correct angle of deflection or 'lead' needed to hit the target when it was moving across the line of fire.

陀螺瞄准镜最终解决了飞行员和空中射手面对的最困难的问题，那就是在目标横越发射线的时候，找到正确的命中目标所需要的前置角度或者提前量。

Because the increasing of dip angle can lead to special strata behavior which cause difficulties to mining, The strata behavior theory can not be simpely borrowed from that of flat and gently inclined seams. In order to cut down roof accidents and increase production efficiency, the strata movement and stress distribution must be reassessed for seam with deep dip angle.

煤层倾角增大带来了矿压显现的特殊性和开采上的困难，不能再简单地借用水平和缓倾斜煤层的矿压理论，而必须对大倾角煤层围岩运动与应力分布予以重新评价，以降低顶板事故，提高生产效率。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
