Results indicate that the fatigue life of CA mortar is logarithmically linear with stress levels and the viscoelasticity of CA mortar guarantees a good fatigue performance at -20℃.

结果表明，研制的CA砂浆疲劳寿命对数值与应力水平呈现良好的线性相关性；CA砂浆的抗压强度受环境温度影响较大，相同应力水平条件下，CA砂浆在负温环境中的疲劳寿命低于在常温环境中的，CA砂浆的粘弹性特点保证了CA砂浆在－20℃环境仍具有良好的耐疲劳性能。

The combined production of vertical and horizontal wells can make horizontal well production rates be 2 to 5 times greater than unstimulated vertical well rates, but the areal sweep efficiency is less than that of vertical well pattern untill when the perforation ratio is greater then a certain value, which depends on the pattern of the combination. Seven spot pattern of the combination of vertical and horizontal wells has some advantages over others.

当水平井和直井联合面积布井时，在同样的压差下，水平井的产量要高于相应直井井网的直井产量的2～5倍，但只有当穿透比达到一定程度，或水平井达到一定长度时，其波及系数才高于相应直井井网的波及系数（五点法井网的穿透比界限为0.521，七点法井网的穿透比界限为0.430），因而在水平井开发油气田时，必须保证水平井一定的长度，这样从长远的观点，水平井才能显示出优势，对比性分析表明，水平井和直井的七点法联合布井和直井井网以及水平井和直井的五点法联合布井井网相比，具有一定的优势，数值模拟表明，在水平井和直井的联合面积布井的各种方式中，改进的九点井网是一种较好可取的布井方式。

In gravid patients, the largest cervical cup from a disassembled KOH colpotomizer is used to laparoscopically delineate the vaginal fornices and atraumatically manipulate the cervix and lower uterine segment by using two ring forceps secured opposite one another to the outer ring.

在妊娠患者中，从拆开的 KOH 阴道切开器中选取最大的子宫颈杯，在腹腔镜手术中使用这种子宫颈杯描绘出阴道穹隆的形状，并使用两叶卵圆钳相互向相反方向抵住外侧，以保证在子宫颈和子宫下段操作中不发生损伤。

Euro area exports have picked up less strongly during the latest cycle compared with previous upturns, and investment—hampered by slow corporate balance sheet adjustment—has been particularly weak.

更概括地讲，虽然货币政策需要集中在整个地区的情况，但是也保证在某些情况下----尤其在单个国家下降的冲击对整个地区有潜在的溢出效应时----采取更积极的的办法。

While by introducing the spherical simplex UT, a better-behaved sigma point selection strategy, the number of sigma points required to the same transformation accuracy can be dramatically reduced, and accordingly, the computation burden can be avoided.

在有陀螺模式下，设计了基于误差修正罗德里格参数的SUKF姿态估计算法，在计算过程中同时能够保证四元数始终归一化。在无陀螺模式，基于MRPs的姿态表示和卫星刚体动力学方程，实现了SUKF姿态估计算法。

In practical project, especially in the condition of soil with badly penetrating ability and lower groundwater level ,can adopt about one meter deepness manual soil laying on the greenbelt and can also design special manual soil depurating equipment around building to dealing with rainwater, which not only assures depurating effect but also saves occupying area and improves environment.

本论文的研究结果表明，经合理设计控制，利用人工加人细砂的土层处理雨水径流，可达到较好的处理效果，实际工程中，尤其是在土壤渗透性很差，地下水位较高等情况下，可以在绿地表层采用lm左右的人工土壤层，'也可在建筑物附近设计专门的人工土壤净化装置来处理雨水径流，既可保证处理效果，又可节省占地和改善环境。

Due to capacity increase or structure change of the power system, an extra-high current possibly 100 times of the rated current may appear in some circuits of the power system when a short-circuit fault happens nearby. This current is extra high and exceeds the permitted value of 10% error curve of protection current transformer.

在电力系统中，各回路的最大故障短路电流和额定工作电流的比值应在合理的范围内，以保证保护用电流互感器的工作精度，但由于系统容量增大或因系统结构等原因，某些回路在某些情况下的最大故障短路电流远远超过了正常范围。

Feed aprons and stock guide plates with different angles and spacing are being equipped inside the cylinder, the structure can ensure that the material being dried runes along the direction of screwing under the impact of gravitation and keeps for a sufficient maintaining times and dispersity in the cylinder to make the material has sufficient heat exchange with the heat airflow from air heating furnace inside of the cylinder.

三筒烘干机是引进欧洲先进技术，由三个不同直径的同心圆筒彼此相嵌组合而成的。筒内装有不同角度和间距的扬料板和导料板，这种结构能够保证被烘干物料在重力作用下沿着螺旋的运动方向运动，在筒内保持足够的停留时间和充分的分散度，使被烘干物料在筒内与来自热风炉内的热气流进行充分的热交换。

The first guard line is a proactive intrusion response method based on intrusion graph, which can make proactive reactions in the forepart in order to prevent the final attacking goals from realizing, furthermore, to protect systems security. The second guard line is an intrusion response method based on damage containment techniques. This guard line will contain damaged data quickly and precisely, then release correct data contained mistakenly just now, which can maintain basic service functions for legal users even though intrusion response has been disabled.

一方面，利用基于入侵攻击图的先应式入侵响应方法，在检测到入侵行为的前期进行防御，在入侵者的攻击目的完全实现之前给予响应，尽量阻止其攻击目的的实现，并采用博弈方法进行策略分析，使系统的响应成本达到最低；同时利用基于数据破坏隔离技术的入侵响应方法作为第二道防线，在前期的入侵响应失效、关键数据已经被破坏的情况下，利用破坏隔离技术精确定位被破坏的数据并迅速释放被误隔离的数据，最大限度地提高数据利用率，从而保证系统向用户提供不问断的服务。

Turn the deck face-down. Slip-cut the top jack into the deck and get a break above it as you place the rest of the deck on it. Execute a riffle-force so you can force the spectator the jack. Ask them to hold on to the jack and as they're doing that, flip the bottom card over do a half-pass with the bottom half of the deck.

这时把观众手中的那张Jack拿过来任意插在下半段面向上的牌里（译者注释：这样就已经有两张Jack于下半段牌面相反了）现在用大拇指break最上面的那张Jack，用double-undercut（两段式切牌+将顶牌移至牌底）把刚才break的那张Jack切到最下面，注意在这个两段式切牌中，第一次切处必须在上半段牌中，这样可以保证观众以为所有的牌至今还都是面全朝下的，第二次切，就是把剩余的那上半段（除去你要移至底部的那张Jack）再切上去。
