Based on analyses of observations from the short-spaced GPS receiver array at Wuhan, the storm-time ionospheric irregularities which resulted in scintillations and rapid TEC fluctuations showed westward drifts between 21∶30 and 03∶00 LT with drift velocities changing from ~40 to ~130 m/s. And based on analyses of observations from the ultra-short spaced GPS receiver chain at Guilin, ionospheric irregularities which resulted in the L-band radio wave scintillations, showed eastward drifts around local midnight ranging from ~70 to ~55 m/s on the quiet-day and westward drifts ranging from ~150 to ~50 m/s before the midnight and eastward drifts after the midnight ranging from ~25 to ~65 m/s on the disturbed day.

The grain size effect on the dielectric properties and ferroelectric properties of the ceramics were measured and discussed.

晶粒尺寸的减小，会引起材料内应力、电畴和晶型的改变，进而会引起材料特性的变化。

The article analyzed the main resources of the uncertainty of the measurement, which include uncertainty of the working curve, uncertainty of the resolution ratio of the instrument, uncertainty of measure unrepeatability, uncertainty of standard solution, etc. It quantified these uncertainties respectively and composed them to a standard uncertainty. Finally it got the expanded uncertainty of the total organic carbon measurement.

分析了测量过程中不确定度的主要来源，即工作曲线的不确定度、测量仪器读数分辨率导致的不确定度、测量不重复性引起的不确定度、标准溶液引起的不确定度等，分别量化后合成标准不确定度，得到总有机碳测量的扩展不确定度。

However, although it has the reliability which like on states high, antijamming ability stronger, but works as production environment is too bad, electromagnetic interference specially intense, or installs uses is improper, possibly creates the program error or the operation mistake, thus produces inputs by mistake and causes outputs by mistake, this will be able to create the equipment out of control and the disoperation, thus will not be able to guarantee PLC the normal operation, will have to enhance the PLC control system reliability, on the one hand will request PLC to produce the factory to enhance the equipment the antijamming ability; on the other hand, in the request design, the installment and the use maintenance cause highly takes, coordinates to be able in every way to consummate solves the problem, effectively strengthens the system the resistance to interference.

然而，尽管有如上所述的可靠性较高，抗干扰能力较强，但当生产环境过于恶劣，电磁干扰特别强烈，或安装使用不当，就可能造成程序错误或运算错误，从而产生误输入并引起误输出，这将会造成设备的失控和误动作，从而不能保证PLC的正常运行，要提高PLC控制系统可靠性，一方面要求PLC生产厂家提高设备的抗干扰能力；另一方面，要求设计、安装和使用维护中引起高度重视，多方配合才能完善解决问题，有效地增强系统的抗干扰性能。

Influence of the antioxidants vitamin E and idebenone on retinal cell injury mediated by chemical ischemia, hypoglycemia, or oxidative stressRego A, SantosM, Oliveira C.. Free Radic. Biol. Med, 1999, 26: 1405 - 1417Abstract:A role for the antioxidants vitamin E and idebenone in decreasing retinal cell injury, after metabolic inhibition induced by chemical ischemia and hypoglycemia, was investigated and compared with oxidative stress conditions.

对由于化学贫血与低血糖所引起的代谢抑制后，抗氧化剂维生素E与艾地苯醌视网膜细胞受损所引起的作用进行了研究，同时并与氧化应激情况进行了对比，对氧化物维生素E(20 microM)和艾地苯醌(10 microM)进行先期培养可以在氧化应激或低血糖后防止视网膜细胞受损，而对上述二种抗氧化剂给予预先培养后带来的保护作用则有所减低。
