＜正＞ The thesis concerns the experiment of decomposing cornstalk in the method of two-phase biotransformation. Such strains as Microzyme S2.8, Bacteria B186, Epiphyte F174, Trichoderma reesi TR-1, Trichoderma koningii TK-2.and Fiber pseudomonas CB-3 have been used separately or as combinations to bio-transform cornstalk. During the transformation course, the diversifications of cornstalk ingredients have been tested and analyzed. The results

橡胶(Hevea brasiliensis)林是热带地区重要的经济林,其土壤碳排放除受温度、湿度等非生物因子影响外,还受到橡胶林独特物候特征的影响。为探讨橡胶林土壤呼吸季节变化与生物、非生物因子的关系,本实验再西双版纳橡胶林内设去除凋落物(NL)和对照(CK)两种处理,自2.05-08到2.06-08,用IRGA法测定土壤呼吸速率(SR),同时测定温、湿度因子;记录橡胶林的物候节律;每月中旬测定叶面积指数;进行为期一年的细根生长和分解试验。结果表明:1)两种处理SR有明显的季节变化,且趋势相同,即雨季(CK:14.10mgCO2.m-2.min-1;NL:13.00mgCO2.m-2.min-1)>干热季(CK:9.91mgCO2.m-2.min-1;NL:9.70mgCO2.m-2.min-1)>雾凉季(CK:10.87mgCO2.m-2.min-1;NL:10.33mgCO2.m-2.min-1);2.通过温度、湿度与SR的相关分析和回归方程模拟,表明两处理各季节SR与温度因子、湿度因子相关关系不同;影响SR的主导因子在雨季为湿度因子,雾凉季是温度因子,干热季SR受到温、湿度因子的双重制约。3)在雨季,凋落物对土壤呼吸影响显著(p=0.036),在干热季和雾凉季影响不显著(p=0.701,p=0.308);4)细根生长试验和LAI的测定结果表明两处理的土壤呼吸速率季节变化与橡胶树生长节律基本一致,生长旺盛期(雨季,5～10月)>生长减缓期(雾凉季,11～12.)>生长恢复期(干热季,3～4月)>相对休眠期(雾凉季,1～2.);5)通过主成分分析,土壤呼吸源的季节变化是影响橡胶林土壤呼吸的第一主成分,方差贡献率为65.98%,第二主成分是地上部分光合产物的输入,方差贡献率为34.02.。两成分可完全解释土壤呼吸的季节变化。故橡胶林的SR季节变化是温度因子、湿度因子及橡胶树生长季相变化协同作用的结果。

C-isotope analysis of the carbonates in the Upper Neoproterozoic in Keping, Xinjiang indicates that the Qigebrak Formation and the Upper Sugaitbrak Formation mainly record positive C-isotope values, and a distinct positive excursion occurs in the lower part of the Qigebrak Formation. There are three negative excursions in the boundary between the Qigebrak Formation and the Cambrian, the uppermost and lowermost Upper Sugaitbrak Formation. These characters resemble those of the Upper Neoproterozoic in the Three-Gorge area, which suggests that the Upper Sugaitbrak Formation and Qigebrak Formation can be correlated with the middle and upper parts of the Doushantuo Formation and Dengying Formation, respectively. The negative excursion at the top of the Upper Sugaitbrak Formation corresponds to that at the top of the Doushantuo Formation, while the negative excursion at the bottom of the Sugaitbrak Formation can be correlated with that at the middle part of the Doushantuo Formation in the Three-Gorge area and that at the top of the Hangelchaok diamictites in the Quruqtagh area.

Rotor Head Vibration Absorber (RHVA) is a new kind of vibration reduc-tion device for helicoper, which provides some advantages in applications. The mechan-ical model for analysing and designing such kind of device is presented, two analyticalmethods (in frequency domain and time domain) and its adaptabihty are studied. At thesame time the charactenstics of RHVA are analysed. The deduced rotor receptancesproved by model test are presented. At last the effectiveness of mechanical model andanalytical methods presented in this paper and of RHVA are illustrated in the calculation example.
