新疆托里蛇绿岩型金矿床中黄铁矿的研究
,周美付,冯延玲,戎合,袁嘉琪
地球学报 , 1987,
Abstract: 在金的伴生矿物中,黄铁矿在托里金矿床中是非常丰富的矿物。它不仅在数量上占优势,而且在本矿床中黄铁矿还以部分自然金的载体出现在矿化带中,所以对黄铁矿进行较为详细的研究是有实际意义的。另外,本矿床为一新型的金矿床——蛇绿岩型金矿,就其黄铁矿来说,无论是矿物学的特点或是地球化学特点都具有本类型矿床的独特性质,例如本黄铁矿中有CO/Ni<1、Au/Ag>1的特点。再者,托里金矿有两个成矿带,而黄铁矿在这两个成矿带中又有不同的特点,这是由于这两个成矿带不同的成矿环境所造成的。

Abstract: 1989年2月在台山铜鼓湾海边对水溶性气溶胶的离子成分cl-、no_3、so=4、na+、k+、mg++进行了分析,发现其中主要离子成分是cl-与na+,它们都来自海盐气溶胶,mg++亦来自海盐;而k+主要是陆源性的;so=4的来源以海盐为主,但也反映出受东亚大陆较严重大面积硫污染影响的特征;而no-3有较高的富集现象,且100%为非海盐成分,应是局地人类活动,如农耕与炊事影响所致。

Abstract:
本论文通过模拟仿真模拟燃料电极支撑的Ni-YSZ/YSZ/LSM平板型固体氧化物电池储能系统,基于相变金属铜进行热能存储与利用,研究该电池系统的电能循环效率。研究发现,开路电压对于荷电状态的依赖要比对系统压力更为明显,平板型电池的极化电阻主要来源于金属电极的活化极化。系统气体和部件等热量平衡可显著影响系统运行温度,因此通过系统保温措施可减少热能损失从而提高系统效率。通过利用金属铜将燃料电池模式下的热能进行存储,而在电解池模式下释放热能以维持电池系统运行,电能的热能循环效率可高达80%以上,满足商业化大规模批量化生产要求的标准。
In this paper, we investigate the heat storage and utilization based on copper metal tank to en-hance the electricity cycling efficiency in the solid oxide cell system with a configuration of Ni-YSZ/ YSZ/LSM. It is found that the OCVs of this planar solid oxide cell system rely more on the state of chare than system pressure and the cell polarization resistances mostly come from the fuel electrode polarization. The system temperature can be effectively changed by the heat balance of gas, cell component and operation circumstance. While the heat loss in the system has a huge influence on the system temperature and electricity cycling efficiency. It is found that the electricity cycling efficiency can reach above 80% of the commercial mass production standards when copper tank is utilized for heat storage in fuel cell mode and heat utilization in electrolysis cell mode.

地球学报 , 1987,
Abstract: The gold deposits in the Toli ophiolite can be divided into Anqi and Sor-tohay ore belts. They differ from the other types of gold deposits in that the pyrite in them is characterized by Co/Nil.Pyrite in the former ore belt is rich in As but poor in Co and Ni, while that in the latter one is rich in Co and Ni but poor in As. The unit cell parameters of pyrite in the Anqi ore belt are larger than those of pyrite in the Sartohay ore belt. There is little difference between Mossbauer parameters of pyrite from the two belt and Mossbauer effect shows that, like other gold deposits the element Au does not enter the lattice of the pyrite.

Abstract: 目的以雅培全自动化学发光免疫分析法(CMIA法)为标准,探讨时间分辨免疫荧光法(TRIFA)检测血清乙型肝炎表面抗原(HBsAg)的准确性和可行性,以便基层医院普遍开展此项目,为抗病毒个体化的策略及疗效的预测提供依据。 方法分别用CMIA法和TRIFA法对157份乙型肝炎病毒(HBV)感染患者的血清进行检测,对于HBsAg滴度超过检测上限的样本,采用稀释液手动稀释后,再进行定量分析。将HBsAg水平分为4组:≤100 IU/mL、101~1 000 IU/mL、1 001~20 000 IU/mL、>20 000 IU/mL,分析两种方法阳性标本定量相关性。结果两种方法的直线回归方程为:Y=2.323X-896.3,相关系数r=0.943,P<0.001。以CMIA法检测值为参考,分为4组进行分析,结果显示在检测低浓度HBsAg样本时,TRIFA数值较CMIA法偏低,而高浓度样本以CMIA法检测值偏高。两种试剂在检测不同浓度的HBsAg均有较好的一致性(均P<0.05),其中以浓度在1 001~20 000 IU/mL时相关性最好。结论两种试剂在HBsAg定量检测上的准确性基本相当,定量相关性以检测值在1 001~20 000 IU/mL之间最佳。TRIFA成本低廉、易操作,更适于基层医院使用,具有广泛的应用前景

Abstract: 针对热压罐升温速率波动导致的成形质量问题,提出基于容差模型和稳健ε-支持向量机的应力松弛成形工艺稳健设计方法,并给出一种改进的容差计算方法。该方法首先建立工艺参数优化数学模型,以塑性应变的导数为优化目标,以材料性能提升率为优化约束;建立优化目标响应曲面、优化约束响应曲面以及优化约束容差响应曲面,计算得优化约束容差并将其引入优化模型中;利用更新后的优化约束可以计算得到稳健的工艺可行域,最终在可行域内求解得到最佳工艺参数。分别采用原始工艺参数和优化工艺参数进行试验,在升温速率波动的影响下,采用优化工艺参数的试验件全部满足约束条件,而采用原始工艺参数的试验件中有30%不满足要求,验证了本文提出的工艺稳健设计方法的有效性和可靠性。
Aiming at the autoclave forming quality problem caused by heating rate fluctuation, this paper puts forward the robust design method of stress relaxation process based on the tolerance model and robust ε-support vector machines, and gives an improved method to calculate the tolerance. The optimization mathematical model for process parameters is established at first and the derivative of plastic strain and the upgrade rate of material performance are chosen as the optimization goal and optimization constraint respectively. The response surfaces of optimization target, optimization constraint and optimization constraint tolerance are established and the tolerance of optimization constraint is introduced into the optimization model; the robust process feasible domain can be calculated after updating optimization constraints and finally the optimal process parameters can be obtained in feasible domain. The original process parameters and the optimized ones are used respectively to carry out stress relaxation experiments. With the optimized parameters, all parts satisfy the constraints. By contrasting, 30% of parts do not meet the requirements with the original parameters, proving the proposed method is effective and reliable
