There were 2 peaks of starch accumulation in the process of somatic embryogenesis,the first time was at the stage of embryogenic callus,the second time was at the stage of globular embryoids;and a small raise appeared at the stage of torpedo-shaped embryoids,and the content of starch was slightly higher than those of heart-shaped embryoids and cotyledonary embryoids.With the development of embryos,the tendency of the changes of the content of DNA,RNA and the total nucleic acids was approximately similar,and the peak values were all at the stage of cotyledonary embryoids,and the change of the content of RNA was more remarkable than those of DNA and the total nucleic acids.The tendency of change of the content of proteins almost took on the S-shaped curve.

Some factors to influence the silicon content of hot metal were proposed on the basis of the experiment in the lab: increasing the binary basicity is favorable to desiliconization; the oxide in slag debases the silicon activity and is of great advantage to desiliconization; Al2O3 and SiO2 are disadvantageous to desiliconization, the volatilization content of SiO2 in coke increases with increasing smelting temperature, leading to increase the silicon content of hot metal; the silicon content of hot metal increases with increasing the drip zone's altitude.

在实验室进行了降低铁水中硅含量的实验，得到了铁水中硅含量的影响因素：提高二元碱度有利于降硅；增加渣中氧化物可降低SiO2的活度有利于降硅；Al2O3和SiO2不利于降硅；冶炼时焦炭中SiO2的挥发量随温度的升高而增多，使铁水中硅含量增加；随着滴落带高度的增加，铁水中硅含量不断增加。

The water content of the water content of the paper, directly influenced the business card printing and membership card to make the quality of the water content, right now, paper strength that is slowing down, the role of the epigene, the paper fiber will be pulled out, so that the plastic deformation increases brand drying rate affected; if the moisture content is too small, the paper will be issued with a crisp, easily damaged, generate static electricity.

纸张的含火量纸张的含火量的多多，间接感化着制卡和会员卡制息品的质量，含火量功多，纸张的不弱量会降矮，在边辛的功用下，纸张纤维会被不推出，使不不弹性变形加不弱，使痕迹的潮湿速量施到感化；如含火量功多，纸张会不收不韧，便当变不败毁坏，爆发静电等。

There are experimental results as follows:(1) Eriophorum comosum Nees shows strong cold resistance in plasmalemma permeability research. The lethal temperature of Eriophorum comosum Nees is the lowest LT_(50 in comparison with another two plants and is lower than -11.5℃ in August 2005 and December 2005; Soluble protein content of each plant is rising before or after cold hardiness. By SDS-PAGE, Protein band is analysed. Band quantity of Eriophorum comosum Nees is the most and its band color is darkest.(2) Soluble sugar content of three plants after cold hardiness are higher than before cold hardiness, moreover soluble sugar content after cold hardiness shows a decline and there is a narrow range in Eriophorum comosum Nees; Free Proline accumulation is changed by cold stress, and cold resistance is relative to free Proline accumulation; chlorophyll content of both three plants, including chlorophyll a, chlorophyll b and chlorophyll a/b, show a decline tendency along with the descent of temperature. Cynodon dactylon is highly sensitive to cold stress.(3) The soil POD and urease activities' absolute value of Erioophorum comosum Nees and Pogonatherum panideumHack were more than that of Cynodon dactylon before or after low temperature stress, especially POD activities.
