Nevertheless, it was Perutz who had gathered all the pieces and who ensured, in the end, that they were correctly assembled.

尽管如此，由于有了佩鲁茨所搜集的全部证据，准确地综合，才保证了最终&七巧板&的拼合成功。

Article 6. The IMCO members have committed themselves to obligate, by domestic legislation, all natural and legal persons on their lands to pay and accept UMEMs for trans-territory transactions within all their territories as valid means of payment, means of clearing and reserve assets, which can be freely converted into their domestic currencies respectively, each UMEM equalling one gram of gold.

第六条各成员承诺自行立法要求本国、本地区法人和自然人在本组织成员的地域范围内接受和使用&货币兑换中介单位&作为跨国、跨地区交往的有效支付手段、结算手段和储藏手段，并保证每1货币兑换中介单位任何时候都能自由地兑换为价值1克金的当地货币。

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。
