The δ〓S value of pyrite, sphelerite and arsonopyrite is in the range of 4. 0‰ and -4. 2‰ with the highest frequency occurring around zero, indicating a uniformed sulfur source. The large variation and mainly negative values (0.2‰~-11. 3‰) of δ〓S for stibnite could be interpreted by isotope fractionation. The carbon isotopic characteristics exhibit a mixing nature of magmatic carbon and organic carbon.
矿床中的热液成因黄铁矿、闪锌矿和毒砂的δ〓S=4.0‰—-4.2‰,呈塔式分布,δ〓S集中在0附近,表明其成矿体系具有均—化硫的同位素组成,而辉锑矿的δ〓S变化范围较大(0.2‰—-11.3‰),除一个样品外均为负值,这是硫同位素分馏作用的结果。

To develop the missile quasi-linear model, a state space model is established for missile dynamics, and function substitution method is used to describe the nonlinear dynamics of missile as linear combinations of functions of given time-varying parameters. With the minimizing variation range of model parameters over the whole design envelope as the optimum aim, linear programming optimum arithmetic is used to determine the model parameters at selected grid points.
为了建立导弹准线性化模型,将导弹动力学描述为状态空间形式;采用函数替换方法将导弹的非线性动力学描述为关于特定时变参数的函数的线性组合形式;以整个设计区间内模型参数变化范围最小为优化目标,采用线性规划优化算法确定了所选网格点上的模型参数。

This item is a new type structure direct-acting overflow valve, which adopts dynamic pressure feedback principle. That is it adds a feedback cavity on common direct-acting overflow valve's core. When there is overfall on valve port, the hydraulic force of valve port will balance with feedback cavity's hydraulic force and spring force, so it can decrease spring's stiffness, just like adding a hydraulic spring, which works together with mechanical spring, so as to minish valve port pressure range.
本项目是一种新型结构的直动式溢流阀,采用动压反馈原理,在普通直动式溢流阀阀芯上增加一反馈腔,当阀口溢流时,阀口的液压力与反馈腔液压力和弹簧力相平衡,从而可以减小弹簧的刚度,等于增设了一根液压弹簧,使其和机械弹簧一起工作,以达到减小阀口压力变化范围的目的。
