Some effective measures were presented to solve bigger prestress loss of mid span in overlong frame and it is suggested that prestressed reinforcement with curve linetype should be adopted in slabs if possible 在次梁与板中为有效利用无粘结预应力筋，建议在板厚许可的情况下尽量采用曲线形预应力筋。
After the localization of the damage , the extent of the damage can be determined according to the relation between the damage extent with the change rate of natural frequencies before and after damage 损伤位置确定后，利用板在这一位置的损伤程度与板损伤前后的频率变化率的关系，可以确定损伤的程度。
Experimental result shows that the non - uniform flux of open channel is single - valued corresponding to the opening angle of the plate and water depth in front of the plate , and satisfies the dualistic function 通过试验可知：细长板开启角度、明渠非均匀流流量与板前水深三者单值对应，并满足二元函数的变化关系。
According to compatible relationships of the rotation angles on the boundaries of rectangle thin plates , the unknown bending moment of each plate is obtained , so the analytic results of the box structure under random loads can be evaluated 通过板与板的边界转角协调分析，求解出每块板四边所受的分布弯矩，从而得到任意荷载作用下箱型结构的解析解。
The thickness varies according to the half - apex angle , and the forming limit half - apex angle is the key which nc incremental sheet metal parts forming process succeeds , it relates to the material and thickness of the sheet metal 变形区厚度的变化与成形半顶角有关，其中，成形极限半顶角是数控渐进成形能否成功的关键，它不仅与材料有关，而且与板料厚度有关。
Lamb waves method is mainly used to characterize thin plate materials , without using very high frequency , it can measure the velocity of transverse wave and longitudinal wave , depth of the plate , and the bonding quality between plates 兰姆波法主要用于表征薄板类材料，无需较高检测频率，可以测得板中纵波和横波的声速、板厚和板与板之间的结合特性等，检测精度较高。
The plate on the elastic foundation is simulated according to the theory of both plane and bending problems , and the nodal displacements on the interface between the plate and the foundation are represented by the displacements on the middle surface of the plate 摘要按平面问题与薄板弯曲问题描述基础板，建立了基础板同地基接触面上的节点位移与板中心面位移之间的转换关系式。
Gives a procedure for predicting the freezing probability under nonlinear cooling conditions and by combining that with the simulation model of rectangular containers , obtains quantitative results of the impacts of the additive on ice storage 给出了非匀速冷却条件下结冰概率的计算方法，并将其与板单元蓄冰装置的数学模型相结合进行数值求解，定量地预测了加入成核添加剂对蓄冰过程的影响。
Therefore , under the certain condition of the profile of open channel , the size of long and narrow plate and installation , the flux can be achieved from the equal flux curve if the opening angle of the plate and water depth in front of the plate are accurately determined 在确定渠断面、细长板尺寸以及安装布置条件下，只要准确测得细长板开启角与板前水深，便可利用等流量线图得知此时的流量。
