The chemical-petrographic types of these meteorites are presented below.Six are unequilibrated ordinary chondrites,including three H3 and three L3;92 meteorites are equilibrated ordinary chondrites,including 24 H-group(13 H4,10 H5,1 H6),64 L-group(2 L4,44 L5,18 L6) and 4 LL-group(3 LL4,1 LL5);the other two belong to stone-iron meteorites.In 6 unequilibrated ordinary chondrites,chondrules are well-shaped,and olivine and low-Ca pyroxene are commonly zoned and have wide ranges of composition.The olivine and low-Ca pyroxene in the other 92 equilibrated ordinary chondrites have similar composition,respectively,and to some degree it reflected thermodynamics equilibration in olivine and lowCa pyroxene.

并根据矿物-岩石学特征，划分了它们的化学-岩石类型：6块属于非平衡型普通球粒陨石(H3和L3群各3块)；92块属于平衡型普通球粒陨石，包括：H群24块(13块H4，10块H5，1块H6)，L群64块(2块L4，44块L5，18块L6)，LL群4块(3块LL4，1块LL5)；另外两块属于石-铁陨石。6块非平衡型普通球粒陨石保存了原始的岩石学和矿物化学特征，包括：清晰的球粒结构、橄榄石和低钙辉石具有明显的成分环带以及极不均一的化学组成等。92块平衡型普通球粒陨石中的橄榄石和低钙辉石显示出均一的化学组成，表明它们达到了一定的热力学平衡。

The effects of non-metallic inclusions on the machining properties of Ca and Ca-S free machining steels,which were made in 18 t ladle by means of powder injection,were presented.

摘 要：研究了在18 t钢包中采用喷粉方法生产的钙系与钙硫系易切削钢中非金属夹杂物对切削性能的影响。

In the course of capacitation, the membrane potential might be depolarized resulting from K〓 or Na〓 influx.

获得精子由于阳离子内流和膜电位的去极化，Ca〓通道开放，此时Ca〓通道阻断剂使通道关闭。

The transmission is conducted in the form of action potentials along the axon of DRG neuron to the presynaptic membrane in spinal dorsal horn. Action potential depolarizes the presynaptic membrane and activates the voltage-dependent Ca〓 channel. The influx of Ca〓 then triggers the release of neurotransmitter.

外界感觉信息以动作电位的形式沿DRG细胞轴突由外周传向DRG细胞在脊髓背角的突触前膜，导致细胞膜去极化，引起电压依赖性〓通道的开放，〓内流介导突触前膜神经递质的释放，从而完成感觉信息由外周向脊髓的传递。

Experimentally, stores can be emptied by increasing of InsP3 molecule in the cytosol, dialyzing the cytoplasm to high concentrations of Ca(superscript 2+) chelators such as EGTA or BAPTA, or treating with the endoplasmic/sarcoplasmic reticulum Ca(superscript 2+) ATPase inhibitors like thapsigargin and cyclopiazonic acid.

尽管这个领域受到愈来愈多的重视，然而，钙池调控钙离子通道所能影响的细胞生理意义或其调控机制，至今所知仍然非常有限。

Methods Forty-four EH patients were dichotomized into two groups to receive Ca(12.5 mg/d,n=22) or slow released Ni(10 mg bid,n=22) and titrated to 50 mg/d for Ca or 20 mg for Ni bid if BP was sustained above 140/90 mm Hg 2 weeks after initiation of treatment.
