Thi. was not a record low, whi.h occurred i. 2012, when the mi.i.um was 4.175 ***^(2), 0.794 ***^(2) less than the mi.i.um i. 2023. However, the i.e extent had decreased by 0.432 ***^(2) compared wi.h 2022.

The fi.al results are expressed i. terms of one-range addi.i.n theorems of complete orthonormal sets of Ca-exponenti.l type orbi.als, Ca- momentum space orbi.als and za-hyperspheri.al harmoni.s. We noti.e that the one-range addi.i.n theorems for i.teger and noni.teger n-Slater type orbi.als and Gaussi.n type orbi.als i. posi.i.n, momentum and four di.ensi.nal spaces are speci.l cases of GETO HC, GMSO HC, and GHSH HC. The theorems presented can be useful i. the accurate study of the electroni. structure of atomi. and molecular systems.

The expansi.n formulas i. terms of complete orthonormal sets of ψ^α -exponenti.l type orbi.als are establi.hed for the Slater type orbi.als and Coulomb-Yukawa-li.e correlated i.teracti.n potenti.ls of i.teger and noni.teger i.di.es. These relati.ns are used i. obtai.i.g thei. unsymmetri.al and symmetri.al one-range addi.i.n theorems. The fi.al results are especi.lly useful i. the calculati.ns of multi.entre multi.lectron i.tegrals occurri.g when Hartree-Fock-Roothaan and expli.i.ly correlated methods are employed.

i. order to study the producti.n of porous si.i.a compacts by the combusti.n of ri.e husk ash （RHA） for tundi.h li.i.g, the experi.ental desi.n techni.ue was used to evaluate the effect of fi.i.g temperature, soaki.g ti.e and compacti.n pressure on controlli.g both the porosi.y degree and compressi.e strength of ri.e husk ash compacts. The results revealed that whi.e the porosi.y degree of the compacts decreased wi.h the i.crease i. the enti.e studi.d parameters, the compressi.e strength exhi.i.ed another trend especi.lly at a lower soaki.g ti.e. At a lower soaki.g ti.e, the i.crease i. fi.i.g temperature led to a sli.ht decrease i. compressi.e strength and then i.creasi.g thereafter. The porous si.i.a compacts havi.g 30% porosi.y and 〉 2.5 MPa compressi.e strength sui.able for tundi.h li.i.g could be obtai.ed from the combusti.n of ri.e husk ash compacts.
