求翻译：采用物理方法，将草酸钙针晶无形态改变地从天南星中分离出来，并利用X-射线粉末衍射法和红外光谱法对针晶的组成进行了鉴定。是什么意思？

Using physical methods, no morphological changes of calcium oxalate needle crystals separated from the Araceae, and the use of X-ray powder diffraction and infrared spectroscopy of the needle crystal composition were identified.

physical methods will be used, calcium oxalate crystal-needle pattern changed from days separated the southern star, and to use X-ray powder diffraction law and infrared absorption of needle crystal composition for the identification.

Uses the physical method, separates the calcium oxalate needle crystal non-shape change from the jack-in-the-pulpit, and has carried on the appraisal using the X- beam powder-diffraction method and the infrared spectrometry to the needle crystal composition.

By physical means, the needle of calcium oxalate crystals without morphology change from Arisaema separated, and using x-ray powder diffraction and needle crystals by infrared spectrum composition of the identification.

By physical means, the needle of calcium oxalate crystals without morphology change from Arisaema separated, and using x-ray powder diffraction and needle crystals by infrared spectrum composition of the identification.
