An eminent Austrian astronomer with a typical old Austrian name, Conradin Ferrari d'Ochieppo, devoted many years of his life to researching ancient astronomy, and, on that basis, he pointed out a particular conjunction of Jupiter and Saturn in the year 7 b.c., probably the "genuine" year of Christ's birth.

奥地利杰出的天文学家康拉定。法拉利。多齐耶波教授，花了数十年的时间钻研古代天文学。他发现，木星与土星曾经极其罕见地排列在一起，并且持续了相当长的一段时间。时年推算为公元前七年，那可能正好是基督诞生的「确切」年份。

The convectional heat transfer coefficients were measured and analyzed at different Reynolds numbers and constant heat flux.

This paper makes further research on the error,caused by use of a single step or a variable step of Runge Kutta to solve the Euler equation of quaternion method, find that the large error results from cumulated error with single step, and when using the variable step,the cumulative error is less.

结果表明，定步长时有很大的累积误差，单位四元数的"单位"性不能得到满足，而变步长有明显的改观，对一般的飞行模拟状态，都能得到较好的模拟结果，可以在实际中使用。

This text will talk about some new methods about the limit of disjunction function in the boundary and the operation of lead number and definite integral.

The boundary value problem for first-order differential equations with a parameter refers to the finite solution condition of equation which includes unknown quantity and its first-order derivative that not only relies on interval value but also relies on the parameter of the equation,which is always settled by fixed point theory or successive approximation method.

含一个参数的一阶微分方程边值问题是指：含有未知量及它的一阶导数的方程的定解条件不仅依赖于在区间端点的取值，而且依赖于方程中的参数。通常它用不动点定理或逐步逼近法来解决。
