In radiation dosimetry there are numerous limitations associated with the measurement of isodose curves and depth-dose distributions in high gradient regions of beams by using conventional measuring systems, such as ionization chambers, diode dosimeter, thermoluminescent detectors, and radiographic films.

在辐射剂量学中，利用传统的剂量计例如游离腔、二极体侦检器、热发光剂量计、感光胶片…等，来量测等剂量曲线或是深度剂量分布都有其适用的范围及其限制。

Kurt watched Covenant assets pour down the transport beams and assemble in the city: more Elites with plasma rifles, titanlike Hunter pairs wielding fuel-rod cannons and nearly impenetrable shields, plasma turrets and their Grunt tenders, and a monstrous Scarab walker.

库尔特看到圣约人的人员装备源源不断的从传输光中落到地面，在城市中集结：更多的拿着等离子枪的精英，巨大的猎人兄弟挥舞着燃料棒大炮穿着几乎无法击穿的护盾，等离子炮塔和它们的咕噜人炮手，还有一个巨大丑陋的蟑螂攻击平台。

The pseudo-static test which subjects to horizontal load on the A-type autoclaved aerated concrete block wall was adopted. Reinforced concrete beams were set up at the upper and lower ends of the test block, and the four-bar linkage device was provided to ensure that the top of the wall was only in translatory motion, not in rotation at the level force. Hydraulic synchronous loading device was adopted to simulate the vertical load which was produced by the wall of the housing interlayer.

对A类蒸压加气混凝土砌块墙体采用水平荷载作用下的伪静力试验，试件的上下两端设置了钢筋混凝土梁，通过四连杆装置保证墙体顶部在水平力作用下只有平动而无转动，并采用同步液压加载装置模拟房屋层间墙体作用的竖向荷载。

If you think that the wind and the rain will bring down the house, cut some pieces of polycarbonate out from the leftovers, and place them transversally, as stiffening beams.

5.4如果担心风雨会摧毁房子，就把一些用剩的板子象承重梁一样加固一下

It is difficult to analyze unbonded prestressed beams by commercial finite element programs with conventional methods.

同时，本文解决了商用有限元程序难以按常规方法分析无粘结预应力梁的问题。

Specimens of 16 unbonded prestressed concrete beams under low cyclic loading were tested.

完成了16根无粘结预应力混凝土梁的低周反复荷载试验。

The analytical results for strength and behavior of unbonded prestressed concrete beams were presented.

At this stage, the defection of the beams increased clearly as the moment of inertia of the cracked section was less than that of the uncracked section.

在这个状况下，清楚地增加的射线的背叛，因为转动惯量破裂的部分的比那是较少uncracked部分。

In addition,the unhomogeneous distribution of atmospheric density leads to refraction of ladar signals propagation,and turbulence in the atmosphere results in energy fluctuation in the cross-section,spread and drift of beams.

另外 ，由于大气密度分布不均匀导致激光沿光路上的折射，大气湍流效应导致光束横截面上能量分布起伏、光束扩展和漂移等，这些对激光雷光信号的传输产生一定的影响。
