concent
2.The concent of free Gin and Ala-Gin in Biocom are 21.1% and 2.65% respectively.
3.After TSN applic ation the Glu release evoked by elevating intracellular free-Ca 2+ concent ration ([Ca 2+] i) with calcimycin also significantly decreased.
4.A hematite rough concent rate with a grade 56.00%and recovery83.36%was obtained by adding 30%bla ck liquor,which was treated with H 2 SO 4 ,into the pulp.
5.The results obtainedfrom 60 samples of bone-ash showed that the average value of the radium-226 concent in bone-ash was 2.1×10~(-14)Ci/g.
6.By analyzing the datum of main root length, root fresh weight , plant height, plant fresh weight, GSH(glutathione)concent and ALS (acetolactate synthase)activity, the following could be concluded : The sensitivity of maize was higher than that of Kaoliang to momosulfuron.
7.The study shows that ethephon and ethy-lene treatments with lower concentrations (1-5 ppm) have a stimulatingeffect or, as it were, no inhibiting effect on the adventitious root form-ation; however, their inhibiting effect becomes stronger as their concent-rations increase.
8.This paper deals with the affact of carbon concent in steels on plasma surface alloying of W-Mo by the double glow dis charging plasma alloying at surface of samples of Armco iron 20#, 45# and T8steels.
9.In this paper, an investigation of the laser chemical etching of the Nickel-ironalloy(Ni=52%) in sodium nitrate solution by using a relatively low power Argon-ion laser hadbeen made, etching rates had been determined as a function of laser power and solution concent-ration, etching mechanism had been analysed.
10.In 1989 CSIRO Minerals initiated investigations into continuous converting of copper matte into low sulfur blister in Sirosmelt type reactors. Following the succe- ssful piloting of this processing route, some effort was directed towards a single stage copper making process where copper metal is made in one step from concent- rate.
