氟钽酸钾钠还原工艺中注钠计量控制方法的研究

对金属钠溶液的多种计量控制方法进行了分析研究，结果表明：采用电阻法来控制注销量及注钠速度，方法不仅经济、实用，而且灵敏度高。该法不仅可以解决国内一些钽粉生产厂家因注销计量控制不灵敏而引起的袒粉质量问题，而且还可以用于其他导电液的计量控制。

化学注浆加固技术在预掘回撤通道顶板切落事故中的应用研究

化学注浆加固技术目前已在煤炭行业中得到广泛应用,特别是在各种顶板事故处理中发挥了积极作用。但是对单位工程总体注浆材料消耗量的控制,主要依靠施工人员的现场经验进行评估,缺少理论支撑,易造成材料浪费。塔拉壕煤矿在工作面回撤通道顶板大范围切落进行化学注浆加固的应用实践中,通过建立力学模型进行理论分析、计算,优化施工方案,改变顶板的力学参数越过垮落边界,进行注浆量控制,在实现工作面顺利搬家回撤的前提下,注浆材料总体消耗量大幅减少,经济效益明显。研究可为化学注浆加固技术在类似条件的工程应用提供参考。

Continued application of Endostar combined with chemotherapy in advanced hemangioendothelioma of bone

By one case of hemangioendothelioma of bone accompanying pulmonary metastasis was treated with rh-endostatin injection (Endostar) combined with chemotherapy. The patient got partial response (PR) for 3 years after the application of Endostar maintenance therapy and Endostar combined with taxane-based chemotherapy. During the period of using Endostar as monotherapy, the patient got long-term disease control and good quality of life. There was no drug related adverse event during the therapy of Endostar. Suggested continued using of Endostar combined with chemotherapy could achieve an convinced therapeutic effect. Then using Endostar as maintenance treatment after patient got the optimal efficacy was feasible and profitable. This treatment strategy of long-term administration of Endostar was worthy of further observation, to explore the feasibility for long-term administration of combined with chemotherapy in the treatment of hemangioendothelioma of bone accompanying pulmonary metastasis.
