恒载荷 meaning in Chinese

constant load
dead load

: 36 < kth < 37 mpa / m3 / 2 , 42 < kih < 44mpa / m3 / 2 , 51 < kc < 52 mpa / m3 / 2 through the sem fractography , it is know that the susceptibility to brittle failure at room temperature is more than below 100 ? . and the susceptibility to brittle failure increase with hydrogen increasing , under the sustained loading , ductile cracking appears . the quantity of brittle cracking is more with crack growth
T44mpa m ‘ q ， sl lt52mpa in ’ ”断口分析表明，该合金充氢后其室温时的氢脆敏感性大于100oc时的氢脆敏感性；且随氢含量升高，氢脆敏感性增加：在恒载荷的作用下，该合金裂二纹开始扩展时显示的是韧性起裂；随裂纹增长，试样脆性断裂的比例增大。
But at present , the static performances of the double reticulated domes applied on the different load combination of wind load , snow load , live load , seismic load and dead load are not adequately studied . also the study on the dynamical response under seismic action is not sufficient
但目前对于这类空间结构在雪载荷、风载荷、恒载荷、活载荷、地震载荷等各种载荷共同作用和各种载荷分布方式下的静力性能研究还不充分，特别是对其在地震作用下的动态响应的研究还不足。
