Using linear creep law of concrete proposed by and Lin, the authors of this paper derive a formula for computing time-dependent prestress loss and camber of two-way prestressed concrete slab taken into account the interactions of concrete shrinkage, creep and steel relaxation. 本文从、林南薰等提出的混凝土的线性徐变定律出发,较精确地计算由混凝土收缩、徐变和预应力筋松弛的相互影响所引起的预应力混凝土构件的预应力损失。
In the framework of the two-fluid model of dilute dusty gases, the present paper gives the governing equations for dusty atmospheric flows, where the two-way coupling is taken into account in the source terms. 在稀相气固两相流的双流体模型框架下,导出含尘大气运动的基本方程,其中的源项考虑相间双向耦合作用;
Vaccae has a good effect on immunostimulation with respect to the two-way immunoregulation; therefore, there are lots of studies about the treatment of chronic Hepatitis B taking into account the combination of Vaccae and HBV vaccine. Vaccae作为双向免疫调节剂,有较好的免疫刺激效果,目前已有较多将Vaccae联合乙肝疫苗治疗慢性乙型肝炎的实验研究。
The scheduling problem of multi-user two-way relay network was investigated in this paper by took different user requirements on rate, delay and fairness into account. 本文通过考虑用户对速率、延时和公平性等各种不同的性能要求,研究了多用户双向中继网络中的调度问题。
During the two-way transfer, China is confronted with severe current account imbalance because of structural problems, which include poor technology innovation capability, low efficiency of financial market, and investment barriers. 在这个产业与劳动力双转移的过程中,由于中国的技术创新能力较差、金融市场效率较低、投资领域存在行政壁垒等结构性问题,中国经济面临严重的外部失衡。
