A variatioual calculation of the energy of the-2s2 is state of helium has been carried out with the use of a wave function of the Hylleraasian typo. The wave function is where s,t u are in units of 4 times the first Bohr radius of hydrogen.

The reaction mechanism between nickel ion and butynediols in the electroless plating process was analyzed. The results show that the change of BOZ concentration is a quasi first-order reaction, the change of the nickel ion concentration is related to the BOZ density, and this change belongs to a higher order reaction. The reaction rate equation was determined as dC/dt=-8.585×10^(-4)+1.188×10^(-4)t-4.64×10^(-6)t^2+5.8×10^(-8)t^3-2.3×10^(-11)t^4. The activation energy of this process decreases as temperature increases, and it decreases with the BOZ concentration as 64-423 mg/L, it increases with the BOZ concentration as 123~240 mg/L. The S value is positively correlated to temperature, when the temperature is 80℃, the reaction rate and S value are the largest; while when the temperature is above 80℃ and BOZ concentration is over 160 mg/L, S value and the reaction rate decrease gradually.

结果表明，镀液中BOZ浓度的变化是准一级反应，镍离子的浓度变化与BOZ的浓度有关，属多级反应，其反应速率方程为dC/dt=-8.585×10^(-4)+1.188×10^(-4)t-4.64×10^(-6)t^2+5.8×10^(-8)t^3-2.3×10^(-11)t^4，反应体系的活化能E随温度的升高而减少，随BOZ浓度的变化而变化：当BOZ浓度在64~123mg/L时，E线性减少；在123~240mg/L时E线性增加。S随温度的升高而增加，当温度达到80℃时S值最大，反应速度最大；当温度超过80℃，BOZ浓度大于160mg/L时，蝎的值逐渐减少，反应速度降低。

For example,the graph in Fig.3-5 is Hamiltonian（a possible path being P→Q→R→S→T→P）but is not quite Eulerian,since any path which includes every dege exactly once（e. g.P→Q→T→P→S→R→Q→S→T）must end up at a vertex different from the initial vertex.

例如，图3-5所示是一个哈密尔顿图（存在一条路P→Q→R→S→T→P）但不是一个欧拉图，这是因为图中任何包含所有边一次且仅一次的路（如P→Q→T→P→ S→R→Q→S→T）都不能回到原出发顶点。

RESULTS The trend of dynamic frequency response of piezoelectric coagulation corresponded with the inverse S curve F =（f0-△f）＋△f/1＋e^（t-t0）/dtderived from theory according to the change regularity of the viscosity and density in the reaction system.

结果 根据反应体系黏度密度变化规律，理论推导出体外凝血反应过程，中压电频率动态响应规律符合F=（f0-△f）＋△f/1＋e^（t-t0）/dt等‰模型；根据该模型建立了新的反S拟合曲线法；与既有的最大拟合曲率法相比，前者检测速度更快（P〈0.01），重复性更好（P〈0.01）。

Methods In order to estimate core temperature T(subscript c from skin temperature T(subscript s, the paper simulated an environmental temperature T(subscript e change. From the change, the paper obtained the thermoresistance ratio of adiabator R(subscript e and body surface tissue R(subscript c, at the same time, deducted environmental temperature T(subscript e influences from the skin temperature T(subscript s. The feasibility and accuracy of the method was tested by a self-made body temperature simulator.
