The results showed that Citrus sinensis green spot disease was a new disease caused by Apatococcus lobatus of Chlorophyta.
结果表明,该病是由绿藻门虚幻球藻属虚幻球藻Apatococcus lobatus所致。
The results showed that Valencia orange green spot was a new disease caused by Apatococcus lobatus of Chlorophyta.
通过对病原进行分离鉴定和生长特性研究,表明该病是由绿藻门虚幻球藻属虚幻球藻(Apatococcuslobatus)所致;病藻的适应温度范围比较广,5 ̄30℃都可生长,15 ̄25℃为其适温范围;病藻具有广泛的光适应性,在500 ̄4000lx的光照范围内均可生长,1000 ̄3000lx为其适宜的光照范围;在pH值为4 ̄10时病藻均能生长,适宜生长的pH值为5 ̄9。
The 3D model is constructed by the triangle-strip method in OpenGL,and the free rotation of the model is accomplished by the method of virtual ball.
采用三角形图元带构建三维模型,并利用虚拟球实现了三维模型的旋转,直观地显示出光束截面光强分布的三维模型,最后讨论了其在测量领域的应用前景。
The paper provided a method to display 3D model,by using OpenGL API technology on Windows platform and reading DXF file format data,and to rotate 3D model freely through virtual ball technology and matrix operations.
在Windows平台上,利用DXF文件格式读取数据,采用OpenGL API技术显示已有的三维模型,并运用虚拟球技术和矩阵变换实现对三维模型的自由旋转,方便了对模型的观察和进一步研究。
