In laboratory studies on the radios and Q-value (SO_3/CaF_2) of low temperature sin- tered portland clinker by multi-factor optimum seeking cross experiments,it is found that the optimum composition are KH=0.95,n=1.7,P=1.4 and q=1.5 when the CaF_2 content in raw meal is 0.8% and the sintering temp. 1320℃.

The application of multi-factor experiment design scheme and single experiment design scheme was compared with statistical significance in their difference (u=2.1236, p=0.0337).

The carbon felt was densified to 1.58 g/cm3 with multi-factor coupling fields CVI,and then it was impregnated with resin/carbonized to 1.85 g/cm3 to make the low cost C/C composites.

Leadership behaviors were measured with the Multi-factor Leadership Questionnaire (MLQ-rater version).

First, we employ a multi-factor GARCH model to estimate the betas.

The results of this work can be extended to a class of derivatives pricing models with path dependent state variables and generalized to multi-factor models.

Two multi-factor nominal and real term structure models are given as examples to illustrate the general model.

The brown alga Laminaria japonica is an important seaweed widely cultivated in this country. The inheritance of its frond length and width has been studied. This paper discusses only the inheritance of the frond thickness.According to our observation the development of the frond thickness was influenced by many environmental and genetic factors.Evidences collected showed that the frond thickness was a genetic character. Firstly, the frond thickness showed a positive correlation of r=0.820 between the parent and the offspring in our experiment. Secondly, the frond thickness of breed II3 was observed to be significantly greater than that of breed H4 for four successive years.The frond thickness was found to be a quantitative character, showing a continuous variation. Multi-factors were believed to control the growth of the frond thickness.The genetic factors were suspected to act on the cell-size and the number of cellular layers in the cortex of the frond. The thick-frond breed H3 possessed six cell layers more than the thin-frond breed H4. Observations on the early growth of the germlings showed that the genetic factors seemed to begin to act in the young spc-rophytes about 2-4 mm long.As the natural population of this seaweed was found to be very heterozygous in genetic content, various inbred lines or breeds with different frond thickness could be obtained by intensive inbreeding and vigorous selection.

By using multi-factor optimization which consists of a climbing method and a method of reduction of dimensions, calculations have been made to choose the structure of the E-coils (the primary -windings of the air-core transformer) in a small tokamak device with non-circular cross-section, with satisfactory results regarding both physics and engineering. For the transfo-rmer structure chosen, the leakage field distribution and isomagnetic linesinside the liner, the magnetic flux distribution and equi-flux...
