The location of the center tubule in the two species is different . in p . trituberculatus it locates at the top of the acrosome tubule , and in s . chekiangenser it locates at the base 脊尾白虾边缘不翻卷，核为泡状核和丝状核，棘突由具等距横纹的纤丝组成，较长。
Trituberculatus has homogeneous sperm nucleus , and s . chekiangense consists of fibrous and condensed sperm nucleus . the number of radial arms in p . trituberculatus is less than the latter ' s . the sperm of p . trituberculatus is round in shape , and that of s . chekiangense is square in shape 罗氏沼虾的精核边缘呈帽沿状向下翻卷，棘突均质，间有等距横纹，精核内有囊泡团存在，棘突较短，核分均质核和丝状核。
Simplified result of earthquake effects indicate that earthquake resistant capacity are obviously scarce and need to be reinforced . secondly , combining with the timber one - dimensional structural characters , the dissertation bring forward the technology that gfrp stick and steel bar reinforce the timber members whose compression perpendicular to grain have excess load and discuss the craftwork how to do the reinforced members 针对木材横纹局压的受力特点和加固目标,本文提出“插筋法”增强古建筑木构件的横纹局压承载力的技术,研究增强机理和加固后的力学性能,探讨制作工艺及在应县木塔中的应用问题。
The key technologies that control wooden pagoda vertical compressive deformation were conducted . for the members that have high damnification and were lacking of bearing capacity need be replaced . northeast larch that has high strength and corrosion resistance is the prime timber , but this timber is easy to crack , so their crack resistance need studied 分析发现,木塔底部几层普拍枋和梁? (柱脚下的横梁)的横纹局压抗力作用效应比最小的仅有0 . 24 ,势必产生过大的变形,是引起木塔高度降低的主要原因,也是木塔当前最大的安全隐患。
First of all , the structural characteristic and essential of damages were introduced . secondly the efficiency factor of how much the compression stress perpendicular to grain is more than the design value was calculated . thirdly , the main reason that members were made too large deformation and serious damage was pointed out 但是,目前木塔残留的整体倾斜、层间侧移以及由木材横纹压缩引起的竖向压缩变形等都已达到严重影响其安全可靠的程度,所以,木材横纹局压增强加固问题亟待解决,以防突变。
Yingxian ancient wooden pagoda is a flat - form tall building , which was formed by the superposition of monolayer temples . the height of 67 . 31 meters made it encountered two unprecedented puzzles : firstly , with the height increased whopping , wind resisting and aseismatic capability become the main question of the whole structure ; secondly , because of the weight increased unconventionally , members of the lower 1 ~ 3 floors hold overloading perpendicular to grain and they brought large vertical deformation 相对于一般殿堂结构,高度和自重的成倍增加,使木塔遇到前所未有的两项难题:其一是因自重增加,使承受上层柱轴向荷载的梁(普拍枋和梁? ）横纹局压应力成倍地超过设计强度而产生严重的压缩变形甚至劈裂,导致木塔整体竖向变位。
