中文拼音 [shuāijiǎndānwèi]
衰減單位
英文
attenuation unit-
The investigation of a lot of parameters about treated sandstone, brick materials and earthen materials with fluorited polymers has been carried out, such as the formation of polymer, the penetration depth, porosity, capillary absorption and penetration coefficient, water uptake, compressive strength, drilling resistance, absorption isotherms of water vapor, water vapor diffusion, color changes as well as resistance to desegregation of water, frizzing - throwing cycles, worming - cooling cycles, and so on. in addition, the influence of salt crystallization, acid and base, and uv aging have also been assessed in order to better understand the protection effects and utilization possibility of two fluorinated polymers, mainly according to astm standard and the combination of international methods together with general technological
分別以國家級文物保護單位的土質、砂巖和磚材文物樣品為對象，依據astm標準及國際通用文物保護研究方法與評估準則相結合，通過膠化物形成周期、滲透深度、孔隙度、毛細吸水和滲透系數、持水量、抗壓強度、抗鉆強度、吸附水蒸氣的能力、透氣性、外觀顏色等系列參數的測定，及凍融、冷熱循環、酸堿腐蝕后抗壓強度的衰減、可溶鹽對保護效果的影響、酸堿及光照對表面保護效果的影響，對兩種含氟聚合物及其與有機硅的共混物在文物加固保護和表面防護中的可行性和保護效果給予了系統研究。The variation of db magnitude attenuation and phase delay of reflection is uniformly proportional to distance along the line toward the direction of reflection, where the phase delay is 360 degree per wave length, the db attenuation per meter is twice the one way db attenuation per meter of forward or backward wave
沿傳輸線之反射，即反向傳播與正向傳播電壓沿傳輸線之相量比，其相位落後及分貝衰減沿反射方向之變化則正比于線長，相位落後為每半波長三百六十度，每米之分貝衰減為正向波或反向波單程每米之分貝衰減之兩倍。With certain field strength, an increase in the space length of electrodes can increase the microwave attenuation. however, the increase of space length of electrodes can increase the microwave attenuation that is adjusted by unit space length of electrodes in a nonlinear way
此外，對不同電極間距下batio _ 3電流變液微波衰減研究表明：相同電場強度作用下，電極間距的增加不僅可有效提高微波衰減的幅度，而且其單位電極間距調控微波衰減的幅度也增加、且是非線性的。Each individual atom retains the exact same probability of decaying in the next hour ( or second, or year - - it doesn ' t matter what unit of time you look at ) as it had before, right up until the moment that it actually decays
在下一個小時（或者下一秒或下一年，你要什麼時間單位，那沒關系） ，每個原子仍然保持準確的同樣衰減或然性，如同它以前一樣，如此一般，直到它實際上衰亡的那一刻。( 2 ) according to the analysis to the single - hole model of blasting, the displacement of the nodes near blasting holes is large but decay rapidly. and this far away from blasting holes is relatively small, decay relatively slowly. after having rising rapidly, the speed of the nodes near blasting holes decays at once
（ 2 ）通過單孔爆破模型分析得出，炮孔附近節點位移幅值很大，衰減迅速，遠離炮孔節點位移幅值較小，衰減較慢；炮孔附近節點速度迅速上升后馬上衰減，遠離炮孔節點表現出大阻尼振動性狀。分享友人
