According to the perturbation method, we also studied stability of the non-convex quadratic programming problem, defined by Tikhonov, A.N.
其次，我们研究的问题可视为Bar-On 与Grasse (1993，1997)问题的条件放松，因此我们可利用Bar-On 与Grasse 方法求得的解来逼近我们研究问题的解，然这就涉及到参数对问题解的连续性，我们期望能以扰动法来回答这「规划问题稳定性」的问题。

The α-BaB〓O〓 crystal is colorless, transparent and without cracking. The cracking problem has been overcome by a special growth procedure. The dislocation density, crystallization morphology and growth habit of α-BaB〓O〓 crystal have been systematically studied by chemical etching method, X-ray laue orientation of synchrotron radiation, double-crystal diffraction topography. The growth striation and irregular dislocation consist of the primary defect in α-BaB〓O〓 crystal. The convex solid-liquid interface is stable during the whole growth process.
在国际上首次采用提拉法生长出φ50×40mm〓的α-BaB〓O〓晶体，生长方向为[0001]，晶体完整、无色透明；提出了三种固相反应的原料制备方法，并保证B〓O〓过量1mol%；采用独特的生长装置和程序有效地解决了α-BaB〓O〓晶体易开裂的问题；首先采用化学腐蚀法、白光X射线衍射术、X射线双晶衍射形貌术等研究了α-BaB〓O〓晶体的位错密度；首次采用同步辐射X射线劳埃定向术研究了α-BaB〓O〓晶体的结晶形态及生长习性；结果发现α-BaB〓O〓晶体的缺陷以位错为主，部分α-BaB〓O〓晶体中存在生长条纹。
