更新1: Hexagonal close-packing: 74.1% 呢?Packing efficiency =volume of spheres in unit cell / volume of unit cell = no. of atom in unit cell X(volume of sphere) / (edge length)^3 For simple cubic packing : Edge length = 2r no of atom in unit cell = 1 Packing effi...
However, all underlying nets of protein crystals in Table 1 are well known and almost all of them (except nets chb, smt, yfh) are fcu and hcp subnets. Interestingly, the 14-coordinated body-centered cubic packing (bcu-x), which is the most frequent in small molecule crystals is rather ...
The elevated temperature of these wastewaters is also a factor. Higher temperatures decrease the oxygen transfer efficiency of aeration equipment, but tend to increase the rate of anaerobic treatment. These considerations are discussed more fully in Chapter 7. As discussed in Chapter 7, the more ...
It is therefore essential to develop energy storage systems that maximize such energy utilization efficiency. In addition, the intelligentization of modern society is resulting in massive demands for off-network energy use, directed to such devices as portable electronics and electric vehicles, which ...

For MBfRs’ design and operation, the key parameters include the packing density of membranes, gas pressure, HRT and surface loading of MPs. The increase of packing density usually enhances the removal efficiency, whereas excessively high packing densities are susceptible to fouling or clogging, also...
