3D mesh vertices ,face was torn,why?

hi gus，i am try to make a music visualizer,i use a sphere to as a response to audio source.

     public void DeformMesh(Mesh mesh, float inRadius) {
         _vertices = mesh.vertices;
         _normals = mesh.normals;
         float _fSqrRadius = inRadius * inRadius;
         for (int i = 0; i < mesh.vertices.Length; i++) {
             if(AudioManager.spectrum[i] >= 0.01) {
                 Vector3 temp = _normals[i] * AudioManager.spectrum[i] * musicStrenth;
                 if (Vector3.Distance(Vector3.zero,temp) >= inRadius) {
                     _vertices[i] = Vector3.Slerp(_originalVertices[i], temp, Time.deltaTime);
 
                 }
             }
         }
 
         mesh.vertices = _vertices;
         mesh.RecalculateBounds();
 
     }

but,Unfortunately, the result is
