The kinematics parameters were firstly presented by establishing the mechanical model of relation between the vibration screen and particle to deduce periodicity condition of particle motion,then disturbing function of particle motion for periodic motion was educed by using Poincaré mapping method,and studied motion characteristics of particle in vibration screening in terms of numerical analysis.

利用振动筛与颗粒之间关系的运动学模型，导出颗粒运动的周期性条件；然后利用Poincaré映射方法，推导出颗粒的运动对周期运动的扰动方程；最后对振动筛分过程中颗粒运动特性进行了数值计算研究，得出了筛面上颗粒运动是经周期分叉和概周期分叉通向混沌的演化过程。

Results The total 100 frontal sinuses were all revealed. Of 100 ostia, nasofrontal ducts, ethmoid infundibula, and middle nasal meatuses, 4 didn't show up and 96 could be viewed with air channel and bone channel structures well demonstrated in 70, and the remaining 26 still showed their bone channel structures though their air channel structures were vanished.Conclusion The structures of the ostium of frontal sinus, nasofrontal duct, ethmoid infundibulum, middle nasal meatus, etc.

结果 50例被检查者的50个额窦全部显示；100个窦口、鼻额管、筛漏斗及中鼻道结构，4个未显示，96个被显示，其中70个窦口、鼻额管、筛漏斗及中鼻道的气道结构和骨结构均清晰可见，26个窦口、鼻额管、筛漏斗及中鼻道的气道结构消失但骨结构仍可见。

In the process of sieving, if the diameter of pill is equal to the diameter of sieve hole, the pills will be clipped in hole of sieve, the fixed scrubbing brush installed in the side of the sieve of the roller can squeeze out the pills.

在筛选的过程中会出现丸剂直径正好与筛孔直径大小一致的情况，将丸剂夹在筛孔上，这时安装在滚筒筛侧面的固定板刷能将药丸挤出。

The lower sieve plate has the same or differnt sieve pore sizes.

所述的下筛分板是漏孔尺寸相同的筛分板或是漏孔尺寸不相同的筛分板。

In this paper, an efficient and easy biological screening method based on the sensitivity to lovastatin of Neurospora crassa was built to deal with the mutant strain rudely by UV mutation. A high-level strain was screened in the shaking flask culture incorporating with TLC and HPLC. A comparison between this two methods also was originally discussed while identifying dyeing using bromophenol blue as the better treatment of TLC, and offering a kind of simple, practical, fast and economical determination qualitatively and quantitatively.

本文有鉴于此，通过紫外诱变处理，并基于粗糙脉孢酶对洛伐他汀的生物敏感性，对诱变菌株进行了初筛；同时，采用摇瓶培养，结合TLC和HPLC的分析方法，复筛出一株高产菌株；对复筛过程两种分析方法分别进行了初步探讨，比较其优劣，确定TLC法经溴酚兰显色剂显色处理为较佳方式；从而，建立了一套简单、实用、快速、经济且有效的洛伐他汀生产菌诱变筛选方法。

And cribriform roof is behind it. On endoscope, we can see anterior ethmoid artery is in the insertio of basal lamella of bulla and frontal sinus, in about 2mm range. They are all behind along ostium of frontal sinus and in front of the basal lamella of bulla, from posterolateral skull base to anteromedial skull base.

鼻内镜下，筛前动脉位于筛泡基板与颅底附着处、前后2 mm范围内，沿颅底由后外向前内走行，其行程始终位于额窦开口后缘的后方和筛泡基板的前方。

The four-point threshold program of YDS-201 perimetry in the fast screening for visual field defect in glaucoma is better sensitivity and specificity. It is a good method for screening on glaucoma in large population of people because of the short time for examination.

YDS-201视野计四点阈值程序在快速筛查青光眼视野缺损中具有较高敏感胜和特异险，检查用时短，适合于青光眼的视野筛查，是一种在大量人群中快速筛查青光眼的良好方法。

The twenty three N-acylalanines which have unsimilar structures and different stereoisomers were used for general, preliminary and second screening tests of fungicidal activities for above four fungi.

最终获得的23种具有不同结构，不同旋光异构体的化合物，再以上述四种致病菌为防治对象，进行了杀菌活性的普筛、初筛和复筛试验。

The present invention is one comprehensive innocuous city solid refuse treating system. In the system, the city solid refuse is first stoved, sterilized and sorted, then magnetically separated to separate out iron containing waste, and finally sieved into the undersize fed to one mixing tank and the oversize further sorted, with the rest matter being crushed and fed also to the mixing tank for fermentation to produce organic fertilizer.

城市固体垃圾无害化、资源化、再生综合利用处理系统，首先将含有大量水分的城市固体垃圾进行烘干、杀菌消毒，进行初级分选，把织物纸类、玻璃、砖头瓦块、废塑料、废橡胶类、废电池、木质类等分拣出来，进入磁选分检出废铁制品，再进入分级筛，筛下物被输送到一个预混罐，筛上物进行再次分选，剩余的垃圾粉碎后也被送入预混罐，在预混罐中加入发酵菌进行混合固体发酵，发酵后成为有机肥。

The optimized sieve parameters reduce the vertical amplitude of the sieve backend, making the grains go easily through the sieve pores to be separated, and consequently help to reduce the grain loss rate and impurity rate.

优化后得到了较优的振动筛参数，有利于减小振动筛后端的垂直振幅，使得谷粒更容易穿过筛孔完成分离，有利于减小损失率和含杂率。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
