In order to analyze the influence of filled metal particles on impact force for hydraulic pile hammer, analytical solution of mathematic model for pile hammer filled with metal particles considering effects of metal particles was presented. In the solution, lumped mass were used as metal particles, a spring was used as contact stiffness between metal particles and hammer body, different variable lumped masses were used as pile hammer, the ram and anvil, a spring and a dashpot were used as the anvil cushion and pile respectively.

为分析填充金属颗粒对打桩锤锤击力的影响，考虑填充金属颗粒的作用，用集中质量块表示填充的金属颗粒，用弹簧模拟金属颗粒与锤体相碰处的接触刚度，用不同的集中质量块表示桩锤、砧座和桩帽，用并联的弹簧、阻尼器表示锤垫，用弹簧表示桩垫，用阻尼器表示桩，建立了平衡方程。

B Through theoretical and experimental studies, the paper investigats the relationships between hammer geometer and stress waveform generated by the hammer. After the mechanical meanings of linear model used by others are demonstrated, a simple expression of rigidity of an equivalent spring for direct impact between a hammer and a rod is obtained. Based on the above work, a mathematical model and numerical method for the impact of the hammer with progressively changing cross-section on the rod are presented.

The genetic analysis was carried out for 8 characters on 9 energy cane parents and their 20 combination crosses with the NCII mating design. The results showed that the inheritance of stalk biomass, brix weight, available stalk numbers and weight per stalk was subject to both additive gene effect and non-additive genes effect, but mainly controlled by non-additive genes. The inheritance of plant height, stalk diameter and brix was subject to both additive gene effect. The broad sense heritability (HB2) of stalk biomass and brix was over 50%, and those of brix weight were 33.7% at the seedling stage 54.4% at its ratooning stage, respectively , which means that the selection would be done better at the early stage in the sugarcane breeding program.

利用遗传交配设计对能源甘蔗9个亲本组配的20个组合、8个性状进行遗传分析，结果表明：地上部鲜重、锤重、丛有效茎数和丛重的遗传既受基因的加性效应也受基因的非加性效应所控制，但以非加性效应为主；株高、茎径和锤度的遗传主要是受基因的加性效应控制，地上部鲜重和锤度实生苗新植和宿根的H_B~2都在50％以上，而锤重的H_B~2分别为33.7％和54.4％，而且锤重和地上部鲜重母本gca方差都大于父本gca方差，说明能源甘蔗育种中母本选择的重要性。

In order to research the sugar accumulating regulation of sweet sorghum, the relationship between the brix of every internode and average brix of its whole stem was studied. This paper used varieties MNS-1, MNS-2 and stem brix of sweet sorghum in different period. The result showed that the variation of early matured and late matured varieties of sweet sorghum had same tendency in brix in same growing period, but had different values.
