一般情况下，一个函数对应一个m文件，且文件名与函数名相同。
由于c写习惯了，尝试将主函数和函数写在同一个m文件中。
格式如下：
function name
主函数主体
function s=name(x)
注意：主函数前不能有代码，比如之类的。

基于NRLMSISE-00大气模型讨论日地空间环境对地球低纬度地区边缘大气密度的影响,提出预测地球低纬地区边缘大气日平均密度的简化模型法和经验法。简化模型法利用地磁活动和太阳活动的11年准周期特性,通过预测地磁活动和太阳活动的变化规律以预测地球边缘大气密度。经验法则直接利用第23个太阳活动周期的日平均密度变化曲线经过傅里叶变换处理得到日平均密度变化规律曲线,然后将曲线拟合得到不同高度下的密度昼夜波动规律,再利用预测得到的日平均密度即可计算出具体当地时间对应的密度情况。误差分析说明经验预测法比简化模型法精度更高。两种方法均具有较高的精度并且使用方便,可用于地球边缘大气密度的工程化预测计算。的翻译是:
目的制备具备关节解剖形态的组织工程骨软骨,行原位移植修复兔关节大面积缺损,探讨组织再生方式及特点,为进一步研究提供研究基础。方法以兔耳原代软骨细胞和第三代成骨诱导的骨髓间充质干细胞为种子细胞,制备具有解剖形态的明胶-硫酸软骨素-透明质酸钠-明胶-陶瓷化骨软骨支架。分为复合细胞组﹙A﹚,无细胞组﹙B﹚和不修复组﹙C﹚。进行体内原位移植,术后不同时间进行HE染色,免疫组化染色及PCR检测。结果复合细胞组与其他两组相比,该组伴随支架吸收同时可以形成大量细胞外基质。而随着体内植入时间延长,不同组别间则出现了明显区别,从HE及免疫组化染色结果观察复合细胞组越来越具备正常骨-软骨组织学表现,而无细胞支架组则表现为纤维化改变。结论修复大面积的骨-软骨组织缺损,需要采用支架复合细胞的方式,单纯采用支架其修复效果是不可靠的。的翻译是:

The laser-induced plasma wakefield in a capillary is investigated on the basis of a simple two-dimensional analytical model. It is shown that as an intense laser pulse reshaped by the capillary wall propagates in capillary plasma, it resonantly excites a strong wakefield if a suitable laser pulse width and capillary radius are chosen for a certain plasma density. The dependence of the laser width and capillary radius on the plasma density for resonance conditions is considered.
