91 The results show that the combustion ablation of oxygen bomb parts and the sample incomplete combustion must be resolved in the combustion heat test for fuel-rich propellant based on boron. 92 The results indicate that taking coal as reductant the ferriferous oxides can be reduced in solid phase, but the boron remains oxidic. 93 Formula of iron - nickel - phosphorus - boron quaternary alloy electroless plating was optimized so as to obtain amorphous deposit. 94 Main boron mineral resources in China are ascharite ore and paigeite. 95 The invention relates to a method for preparing boric acid in boracic sodium chloride and potassium chloride saturated bittern solution containing boron. 96 The document also recommends that engineers continue adding boron to cooling water to help prevent the cores from restarting the nuclear reaction, a process known as criticality. 97 The Influences of Ti content on austenite gain size and grain coarsening temperature in medium-carbon boron steel have been investigated. 98 A novel method for synthesizing a series of tribromomethylarenes by halogen exchanging of trichloromethylarenes with boron tribromide was reported. 99 Boron and boride have been widely applied to modern industry. 100 The separation of boron isotopes is studied by tunable TEA CO2 superradiance laser. 101 This article introduces a new kind of copper, chrome and boron alloy cast-iron cylinder sleeve. 102 Boron with chromotropic acid reacts to form a strong fluorescent complex. The determination of total boron in boron sludge is performed fluorescently. 103 Acceptor - An element, such as boron, indium, and gallium used to create free hole in a semiconductor. 104 But boron also exhibits rapid and significant phloem mobility in species for which sorbitol, mannitol, or dulcitol are the primary photosynthates since these polyols can effectively complex boron. 105 This instrument has been used for measuring the sheet resistance distribution for Boron diffusion chip. 106 The boron trifluoride (BF3) is supplied with excellent quality in a long term steadily, both through imported product and domestic one. 107 The role of boron in inhibiting dezincification of aluminium brass was investigated by ICP, XRD, EMPA and PAT methods. 108 Macrosegregation of boron in vacuum melting pouring ingot of GH901 alloy is determined by 3 characteristics of boron in the GH901 alloy. 109 In this paper, boron ion implantation into base region of power devices is described. The principle of the process and specific process scheme are elaborated. 110 Through evaporating experiment in salt field, the high quality of sylvite, mixed substance of boron, potassium, lithium and iodine were produced. 111 The results show that: the transformation range of lower bainite is enlarged and the start temperature of bainite transformation is lowered by addition of boron. 112 The PPVK films thus obtained showed good redox activity and high electrochemical stability in boron trifluoride diethyl etherate. 113 Lining plate of high boron cast alloy is produced with boron which is rich and cheap as main alloy material. 114 Furthermore, the chemical interaction between interstitial boron atom and antiphase boundary was also discovered. 115 The combustion wave temperature profiles and the flame structures of fuel-rich propellant based on boron were measured by using W-Re micro-thermal couple and flame photo technique. 116 Boron substituted mesophase pitches were synthesized by co pyrolysis of different coal tar pitches with pyridine borane complex. 117 It has been demonstrated that the boron segregation at austenite grain boundaries in quenched steel is a non-equilibrium grain boundary segregation phenomena occurred during cooling. 118 Results of practice show that boron glaze is of high-performance, non-poisonous and low cost. So it is able to substitute for lead glaze. 119 This paper discussed the formula of CBN(cubic boron nitride) resin abrasive tools which was prepared with modified phenolic resin with bismaleimide(BMI/AEF) as bonding agent. 120 In out world, the fracturing fluids applied in the coalbed methane include water, gel, boron cross-linked gel and foam fracturing fluid.
