For laminate containing penetrated crack , " two planes " model is introduced to analyze the influence of repair parameters on the strength of repaired laminate , including such as patch size , patch thickness , patch layout , the location of rivets 摘要针对含穿透性裂纹的损伤层压板，采用“两板”模型建立起机械连接修补结构有限元分析模型，分别计算补片大小、厚度、铺排方式以及连接件位置等修补参数对修补效果的影响。
Conclusions the peak operated well within accept - able safety limits and may greatly facilitate both posterior segment surgeries ( eg , membrane dissection and sheathotomy ) and anterior segment procedures ( eg , capsulotomy , nonpenetrating trabeculectomy , and iridectomy ) 讨论： peak在安全界限内是可以接受的，并且在后节手术（例如膜切开术和鞘切开术）和前节手术（例如晶状体囊切开术，非穿透性小梁切除术和虹膜切除术）中非常容易操作。
According to the excellent penetrability of vapor , the wetting machine of chinese traditional medicine words in the follwing principle ； medicina materials are in the vacuum an low temperature vapor is piped in , the vapor rapidly go into the inner of medicine , and in arapid way the medicine materials are soften symmetrical 中药润药机是根据蒸汽具有强力穿透性的特点，将处于真空状态下的药材，通入低温蒸汽，蒸汽快速穿透到药材内部，使药材快速均匀软化。
This article gives the subsistent ability and the analysis result of intensity after repair in the open field airplane composite material structure by research the intensity , rigid and repair problem under a axis compress loads on a typical three stiffened composite laminate which has a penetrability crack ( a scatter damage ) by a shrapnel 本文通过飞机典型复合材料三加筋层压板结构在被弹片划开一穿透性切口(离散源损伤)后，在轴向压缩载荷作用下所产生的强度、刚度以及修理问题展开了技术研究及探讨，给出军机复合材料加筋板在弹击后生存力以及外场修理后强度恢复分析结果。
Solidness , which indicates that solid objects in the real world do not pass through each other when they collide , contributes to improve realism . enforcing this property is important in interactive graphics applications , especially large - scale virtual world with high demand on realism ; as a result , collision - detection is necessary “不可穿透性” ，即交互图形系统，尤其是虚拟世界应用中的物体，若发生碰撞，不能毫发无损地穿透彼此，是真实性的一个重要的体现和要素，因此，碰撞检测十分重要。
High obstruct multiple bottle is a new packing bottle used for pesticide and chemical , high obstruct material possesses a strong capability that could prevent from infiltrating and ingressing of other material such as pesticide . the packing bottle which be made of high obstruct material , it is has high resist - penetrability , high resist chemical causticity and high stability . it s structure at least have 3 layers , the thickness and the materials of each layer , is designed and made according to the character of pesticide , impregnant or reagent aid 高阻隔材料具有很强的阻止另一种材料如农药渗透进入的能力，采用高阻隔材料生产的包装瓶，具有很强的抗穿透性耐化学腐蚀性和稳定性，其结构至少有三层，各层的厚度和所用的材料是根据所盛装的农药溶剂或助剂的性质精心设计制造的，如它所包装的农药在保质期内，其失重几乎可以忽略不计，而且瓶体具有强韧耐冲击高阻氧及环保性能强等多种特性，特别适用于农药以及其他化学品的包装。
X - ray has been widely used in industry and medicine since it was found in 1895 , such as nondestructive detection of cavities in objects using x - ray " s property of penetration , trace element analysis using x - ray fluorescence , radiation therapy using x - ray " s ability to damage protein , and so on X射线源在生产和医疗上一直以来具有广泛的应用。利用x射线的穿透性可进行无损探伤；利用x射线的荧光效应可对物质进行痕量分析；利用x射线使蛋白质变性可对肿瘤进行放疗。
