350Mpa . And they are widely suitable for primary crushing of many kinds of mining and rock such as many kinds of ores, concrete, fireproof material, bauxite, quartzite, corundum, perlite, ironstone, basalt, etc.

它们被广泛适用于初级破碎多种采矿和摇滚等多种矿石，水泥，耐火材料，铝矾土，石英，刚玉，珍珠岩，铁矿石，玄武岩等

Because of detection limitation, the gold particles are not found independently in pyrite, scheelite, quartz, and other minerals. So it is believed that submicroscopic gold can be found in gold-bearing minerals as micro-inclusions or isomorphous atoms.

由于受检测手段所限，在含金黄铁矿、白钨矿、石英等矿物中未发现独立金颗粒，所以寨上金矿次显微金呈微包裹体形式存在于载金矿物中或呈类质同象替代的原子形式存在。

Because of detection limit the gold particles are not found independently in pyrite scheelite quartz and other minerals. So it is believed that submicroscopic gold are occurred in gold-bearing minerals as micro-inclusions or isomorphous atoms.

受检测手段所限在含金黄铁矿、白钨矿、石英等矿物中未发现独立金颗粒，所以我们倾向于寨上金矿次显微金呈微包裹体形式存在于载金矿物中或呈类质同象替代的原子形式存在。

A slim azimuth 20 independent-arm caliper logging tool;2. Design of TFY-1 universal azimuth jointer with a restrained gyroscope;3. The pit shaft parameters of the elevation angle,the azimuth angle,the tool of facial angle and so on are obtained after the computation.

陀螺测斜技术以动力调谐速率，陀螺测量地球自转角速率分量和石英加速计测量地球加速度分量为基础，经计算得出井筒的倾斜角、方位角、工具面角等参数。

The range of this soil can include organic materials like Kieselguhr and flint or inorganic materials like quartz.

这种土壤的范围可以包括象硅藻土、打火石这样的有机材料，或者象石英这样的无机材料。

Yield, give in, succumb, knuckle under, buckle under

n。 钇铁石榴石材料具有低于石英的声衰减的一种合成材料，尤用于激光调节

Kunzite is relatively hard, with a hardness of seven just like quartz.

kunzite比较硬，有七个像石英硬度。

Lazurite is a type of colored crystal glass,main ingredients are:acid washed quartz and feldspar、potassium nitride（KNO3;to lower temperature）、magnesium chloride（MgCl;help melting,increase it's endurance）、aluminum oxide（increase luminous and chemical tolerance）、lead oxide（international standard for crystal at least 24﹪,lead can increase the color transparency、weight.

琉璃属於彩色的水晶玻璃，其主要原料是精选强酸洗过的石英砂及长石、硝石（硝酸钾：KNO3；降温）、咸土金属（氯化镁：MgCl，助熔、增加耐久性）、氧化铝、氧化铅（水晶玻璃一般国际要求标准24﹪以上，铅可使颜色通透光亮，曲折率高、增加重量感。

The method is testified by experiments on the leftwards spiral quartz beam, and the results of the experiments coincide well with the results of calculating.

以左旋石英晶体为例，依据对扭转效应产生的极化电荷与电场的分析结果，有效地布置了检测电极，从而实现了单压电体扭矩检测，得到了同理论计算结果相符合的实验数据。

The adsorption behavior of metal ions on the silicate minerals such as quartz, beryl, spodumene, lepidolite, garnet, and the flotability of such minerals activated by the metal ions were studied.

研究了石英、绿柱石、锂辉石、锂云母、石榴子石等硅酸盐矿物对金属离子的吸附规律及矿物经金属离子活化后的浮游性，并结合矿物晶体化学特性对实验结果进行了分

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
