Abstract : the forced state in key parts and their lifetime, the volume of high pressure chamber and ratio of pressure, the length of high pressure stroke and pressure stability, the relations between the deformation of high pressure chamber and temperature field and pressure field for three kinds of apparatus of making synthetic diamond under high pressure and high temperature were compared in this paper. the differences of these main apparatus were analyzed according to the degree of difficulty and ease in the technique, the choice of applicability and the cost and yield of them. it was emphasized that studying and developing the large sized belt - type press should be the way to make high quality saw diamond and change the state of making middle and low quality diamond in the diamond industry of our country, catching up with the international advanced level as well
文摘:通過對高溫高壓合成金剛石3種主要裝備在關鍵部件受力狀況與使用壽命、高壓腔體積與壓力利用率、高壓沖程大小與壓力穩定性，高壓腔變形與溫場、壓場的關系等方面的比較，分析了3種主要裝備在技術難易程度、適用性選擇和投入產出比的差異；強調了我國金剛石行業要改變當前只能生產中低檔金剛石的現狀，向生產高品級鋸片級金剛石的方向發展，與國際接軌，應該走大型化兩面頂的道路。 -

The improvement of the news report on abrupt affairs has become a hot topic. this paper is divided for three parts to discussion and analyse the abrupt affairs report. the first part mainly compared the abrupt affairs report of chinese and foreign country in five aspect : the concept, contents of report, the way of writing, technique of expression and its influence. the second part emphasizes on the ability of intuition judgment need for catching abrupt affairs. the final part of the article focus on the characteristics, principle and requirements of the abrupt affairs report
本文分三部分進行探析：第一部分主要從觀念、報道內容、寫法、表現手法以及對受眾的影響程度等五個方面對中外突發性事件報道進行比較；第二部分著重圍繞記者對突發事件的捕捉需要直覺判斷能力等兩個方面進行論證；文章的最後部分，重點從突發事件的特點、原則、要求三個方面進行研究。 -
The synthesis of midbody lactide for the preparation of pla is also catching more attention in this field. the present situation of lactide synthesis is high reaction temperature and low production ratio which lead to its high production cost and hamper its application in the material. the present research hot spot mainly focus on the improvement of reaction technique as well as the selection of catalyst
制備聚乳酸的中間體丙交酯（ lactide ）的合成也越來越受到重視。丙交酯的合成長期以來存在合成溫度高，收率較低的現狀，以至生產成本偏高，不能比較經濟規模化地應用於材料領域。研究的熱點主要包括丙交酯合成工藝條件的改進，催化劑的選擇與優化。
