用于计算分析杆单元的刚度矩阵，应力应变。(It is used to calculate and analyze the stiffness matrix, stress and strain of the bar element.)

说明：  1、定义一个数据缓存buffer及用于实现同步互斥的信号量。 2、定义一个读者函数： ?当有写者在占用buffer时，读者应该等待，直到写者不再使用该buffer。 ?当有其他读者在占用buffer时，读者可对buffer进行读取操作。 ?当buffer中有数据时，则从其中读取一个数据，并显示然后退出。 ?当buffer中没有数据时，应等待，直到buffer中有数据可读。 3、定义一个写者函数 ?当有读者在占用buffer时，写者应该等待，直到所有的读者都退出为止。 ?当有其他写者占用buffer时，该写者应该等待，直到占用buffer的写者退出为止。 ?当buffer有空闲时，写者应该在buffer中写入一个数据并退出。 ?当buffer满时，写者应该等待，直到buffer有空闲为止。 4、定义主函数，在其中可以任意创建读者与写者。 可根据用户输入创建读者或写者进程(线程)。(1. Define a data buffer and semaphores for synchronization and mutual exclusion. 2. Define a reader function: When a writer is occupying the buffer, the reader should wait until the writer no longer uses the buffer. When other readers occupy the buffer, they can read the buffer. When there is data in the buffer, read a data from it, display and exit. When there is no data in the buffer, wait until the data in the buffer is readable. 3. Define a writer function When a reader is occupying the buffer, the writer should wait until all readers quit. When other writers occupy the buffer, the writer should wait until the writer who occupies the buffer exits.)

翅片上冷凝 udf，由于存在shadow必须考虑两侧冷凝udf。所以需要考虑两侧相变传热传质(The condensation of UDF on the fin, due to the presence of shadow, must be considered on both sides of the condensing udf. Therefore, it is necessary to consider the heat transfer and mass transfer on both sides)

说明：  将wav格式音乐文件导入，便可对其进行简单控制应用操作，如 播放与暂停，循环播放，切换下一首歌曲功能，所使用机器为4位机，用最为简陋的芯片也实现8086与51的功能。(By importing the wav format music file, we can simply control its application operation, such as playback and pause, circular playback, switching the next song function. The machine used is 4-bit computer, and the function of 8086 and 51 is also realized with the most rudimentary chip.)
