Spodumene replaces feldspar. Would decrease high temperature viscosity of glaze flux, and improve the glossness of glaze and abrasion resistance.

采用锂辉石代替部分长石，显著降低了釉的高温粘度，提高了锆乳浊釉的釉面光洁度和耐磨性能。

During the second crystallization peak, XRD continues to detect spodumene indicating, however, the additional production of cordierite and indialite which are, now, the main crystalline phases.

在第2个结晶化高峰间，XRD分析显示锂辉石仍然存在，但主要的结晶态为额外产生的堇青石和印度石。

Spodumene is also used as a chemical boost and to increase production efficiencies. American Minerals is the exclusive distributor for Sons of Gwalia, Ltd..

除了能降低产品的烧成温度，达到减少成本目的之外，此中锂辉石还可以作为化学催化剂以提高生产效率，目前，美国矿物公司是Sons of Gwalia有限公司的唯一分销商。

Li_2O-Al_2O_3-SiO_2 System low thermal expansion porcelains based on spodumene were stud- ied systematically to obtain the ceramic bodies with the thermal coefficients lower than 2×10~(-6)/℃(20~800q℃) near zero expansion.

本文系统地研究了以锂辉石为基础的Li_2O-Al_2O_3-SiO_2体系低热膨胀陶瓷，获得了热膨胀系数小于2×10~(-6)/℃以及接近于零膨胀的陶瓷坯体。

On an uncharged lithium tantalate surface, the water remained a supercooled liquid down to –12.5 degrees C.

在不带电的鉭酸锂表面上水可以在-12.5摄氏度时仍处于过冷的液态。

The Raman scattering spectra of lithium tantalate crystals with different compositions were investigated.

1前言钽酸锂(简称LiTaO3，LT)晶体是一种非常优秀的人工材料，在压电、电光和非线性光学等方面都有广泛的应用[1，2]。

By using opposite sides of the same pyroelectric lithium tantalate crystal, the Weizmann team produced two surfaces with opposite charges during cooling—one surface developed a positive charge as the temperature decreased, the other a negative charge.

通过使用同一种热电物质——鉭酸锂晶体的两个对面，魏茨曼团队在制冷过程中制造出了两个带有异种电荷的表面——随着温度下降，一个表面带上正电荷，另一个表面带上负电荷。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
