    In this paper, a liquid paraffin as oil-phase is introduced into the system which is called twoliquid phase fermentation system. The yield of penicillin is enhanced by 0. 2 to 0.5 times at two percent oil fraction. The theoretical explantion for this fact is given based upon the experimental data measure for volumtric oxygen transfer coefficients (K_La) and on physical and chemical properties of both oil and aqueous phases.
    A liquid paraffin as oil phase was added to penicillin fermentation process to increase medium oxygen transfer.

    A liquid organic borate crosslinker, SD2 2, is developed for various plant gum fracturing fluids (FLs). The synthesis and physical characteristics of SD2 2 are described briefly. Six plant gum/SD2 2 FLs are formulated from HPMoyu, HPTQ, HPLJ and HPG and the changes with time in apparent viscosities of these gelled FLs at 80℃ are investigated.
    Through a discussion on 9Ni steel welding of a liquid ethylene storage tank of 10000 m3 in Yang Zhi Petro-chemical Works (See 《petroleum Engineering Construction》 Serial No. 131),welding rod and welding process of 9Ni steel spherical storage tank,this article puts forward some existing and easy-neglected problems and soluton. Futhermore it presents proposal on selection of welding material and its application.
    Assume that the sea bottom is a liquid layer over a porous elastic solid halfspace, using the concept of wave impedance, the phenomenological formula of the reflection coefficient at the liquid layer surface is derived.
    A liquid penetration method for Nb/20Cu composite fabrication is presented. The microstructure and the properties of the Nb/20Cu composite are also investigated in detail. The results show that the electrical and thermal conductivities, oxidizationresistance and mechanic properties of Nb/20Cu are better than those of pure Nb made by powder metallurgy.
    The preforms adapted were carbon felt disks (160 mm od×80 mm id×10 mm thick of each),which have been densified in a liquid carbon source.
