In only 12 month, Tanan Shenran 150 thousand M3 per day LNG project has finished the work from the very beginning to the very end. This project has created a milestone on China gas history, it is not only the first on constructing period, but also make many first on technology: The first self-owned intellectual property LNG plant which is nitrogen expanding and recycling refrigerating in China; the first plant which are all made in China; the first plant which use the parallel connection temperature expander refrigerate technology; the first use the pressure dryness vaporizer technology on Nitrogen gas liquefaction and purity system; the first use the deep fat stove technology in purity system; the piston nitrogen compressor is the biggest in China and etc.

短短12个月内，泰安深燃日产15万立方米液化天然气工程项目完成了从立项到投产的全部建设工程，该套项目的顺利投产完成创造了中国燃气史上的一个新的里程碑，不仅在建设周期上创造了第一，在技术方面同样创造了多个第一：我国首个具有自有知识产权的氮气膨胀、循环制冷液化天然气设备，填补了国内在这一技术领域的空白，对我国名族天然气液化事业的发展产生了积极的推动作用；首次实现设备国产化达到100%；首次采用并联双温区的膨胀机制冷技术；首次将等压干燥脱水技术应用于天然气液化系统、净化系统；首次在净化系统采用了导热油炉、单炉双温区共用形式；所采用的单级双列活塞式氮气压缩机位国内最大等技术。

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。

The first thing we need to do is determine the mean ecliptic longitude of the sun for your chosen day. Use this table to get a first approximation.

We also introduce a control function, prove the global convergence, and prove the local superlinear convergence under some conditions. Then we propose another new algorithm by using an existed approximation functions, which has the same characters as the first algorithms does. Finally, the result of the numerical experiments indicates the efficiency of the first algorithm. The paper contains four parts.

本文还引入了新的控制函数，并证明了算法具有全局收敛性和在一定的条件下具有局部超线性收敛性；然后，在第一个算法的基础上，本文利用已有的光滑逼近函数提出了另外一个新的算法，通过适当参数选取，证明了新的算法具有与第一个算法同样良好的收敛性质；最后，通过数值计算说明了算法的高效性。

In ancient days, one who wished to advocate and enhance the untarnished human heart to make it known to the world must first run his country well must first put his family in order; one who wished to put his family in order must first cultivate himself; one who wished to cultivate himself must first correct his attitude; one who wished to correct his attitude must first make his will sincere; one who wished to make his will sincere must first strive to acquire ever more knowledge. The way to acquire knowledge is to study the phenomena of nature.

古代那些想把自己的美德彰明于天下的人，先要治理好自己的国家；想要治理好自己国家的人，先要整顿好自己的家庭；想要整顿好自己家庭的人，先要修养自身的品德；想要修养自身品德的人，先要端正自己的心思；想要端正自己心思的人，先要使自己的意念诚实；想要使自己意念诚实的人，先要尽量延展自己的知识；延展知识的途径在于穷究事物的道理。
