Because of the lower rock fragmentation efficiency and defective geometrical shape of chisel bit, Sweden has replaced chisel bit with taper connecting cross chisel bit and button bit since the mid seventies.

中文摘要：因一字形钎头破岩效率低和几何形状结构缺陷等问题，瑞典从70年代中期就用锥体连接的十字和球齿钎头取代了一字形钎头。

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.

实验结果表明：(1)在膜透性的研究中，丛毛羊胡子草抗寒性最强，采用电导率法测得半致死温度LT_(50最低，丛毛羊胡子草抗寒锻炼前后半致死温度LT_(50均小于-11.5℃；在可溶性蛋白含量研究中，抗寒锻炼前后三种植物的可溶性蛋白含量均增加，同时采用SDS-PAGE法，通过对蛋白条带分析，以丛毛羊胡子草条带数最多且着色深；(2)在可溶性糖的研究中，三种植物经抗寒锻炼后叶片可溶性糖含量都比抗寒锻炼前高，且经过抗寒锻炼后三种植物可溶性糖均呈下降趋势，丛毛羊胡子草可溶性糖含量下降较小；从游离脯氨酸含量可知，低温的胁迫影响了植物叶片游离脯氨酸的含量变化，植物的抗寒性与游离脯氨酸有关；低温胁迫下三种植物叶绿素含量随着温度的下降，叶绿素含量、叶绿素a、叶绿素b和叶绿素a／b均呈下降趋势，狗牙根对低温胁迫最为敏感；(3)低温锻炼前后，丛毛羊胡子草和金发草的土壤过氧化物酶与脲酶活性的绝对值均大于狗牙根的，特别是过氧化物酶，说明丛毛羊胡子草和金发草的酶活性大于狗牙根的。

The effect of improvement on planosol by the application of the four types of ploughs suggest that there were hard clods between two chisel if the cultivate depth is less than 40cm; there are hard triangle clods between two chisel if the complete deep cultivate reach 40 cm and soil hardness is 20～40kg/cm〓 if the cultivate horizon is shallow or below 20 cm, the expected effect of improvement will not be obtained.

3应用三段式心土犁的土效果。不同改土机械改良白浆土对比试验结果表明：各种深松耕深不足40cm，且深松铲之间存在硬隔，达不到预想的改土效果。

The expected life of new series of bit is 2 to 4 times of that of the chisel bit and button bit, and the price is only one fifth to one third higher than that of chisel bit and button bit.

新系列钎头寿命为一字、球齿钎头寿命的2～4 倍，而价格仅比同直径一字、球齿钎头高1／5～1／3。

In the new process, middlelowtemperature waste heat is used as heat source and LNG cold energy is divided into the lowtemperature latent cold energy and the hightemperature sensible cold heat. Nitrogen Brayton cycle recovers lowtemperature latent LNG cold energy, while the ammoniawater Rankine cycle recovers the hightemperature sensible LNG cold heat, whereby the graded use of energy can be realized. The exergy efficiency of LNG cold energy utilization can be effectively improved.

流程中以中低温余热为热源，并将LNG冷量分为低温级的潜热冷量和高温级的显热冷量两级，氮气Brayton循环回收LNG低温级的潜热冷量，氨水混合物Rankine循环回收LNG高温级的显热冷量，实现了能量的梯级利用，有效提高了LNG冷能利用的火用效率。
