可测的

A data acquisition and data analysis software for the fast fluorscence kinetics fluorometer of our laboratory is redesigned and recompiled using assembly and BASIC language. The data acquisition rate in the fast rising part of the fluorescence kinetics curves is one order faster (100μs/point) than the old one. It can measure fluorescence parameters, such as Fo and Fi more accurately for calculation of the relative content of inactive PSⅡ, etc.

用接近于待测样品中所含的卤代烃的杂质样品与纯净六氟化铀可配置出已知卤代烃含量的"杂质标样"。

Flow cytometric also used for analysis the levels of reactive oxygen species, Ca2+ and mitochondrial membrane potential in both cell lines. The results showed Gyp promoted ROS and Ca2+ production and decreased the MMP level. Western blotting show that Gyp treatment gradually decreased the levels of anti-apoptotic protein (Bcl-2), but increased the levels of the pro-apoptotic protein.

除此之外，也藉由流式细胞仪分析测得经绞股蓝皂甘作用后的人类血癌细胞（HL-60）和小鼠血癌细胞（WEHI-3）里的活性氧化物浓度上升、钙离子释放以及粒线体膜电位下降等细胞凋亡重要指标，此结果可经由西方墨点法指出绞股蓝皂甘能使癌细胞中的抗凋亡蛋白Bcl-2表现量下降；促凋亡蛋白Bax表现量上升，同时也藉由共轭焦显微镜观察到致死蛋白AIF、Endo-G从粒线体释放至细胞核。

Meanwhile, The complicated computation of the laying-out procedures can be accomplished by means of PC-E500S or CASIO calculators to make the laying-out operation various and productivity improved obviously.

本文介绍一种新的方法，任意点设站坐标逐点逼近法，即利用可编程计算器或便携机配合全站仪，用坐标法进行路堑开挖线的放样，相对于传统方法，该方法不但在效率和精度上都有较大提高，而且可以根据需要和现场情况任意设站，使开挖线的放样更加灵活[2]。1施测原理1.1资

It is not only a task of economic science to discard the errors concerning measurability in the field of action. It is no less a task of economic policy.

抛弃那些关於行为领域里面的可量测性的谬见，不仅是经济科学的义务，经济政策也同样有此义务。

The navigation satellite system is a key space infrastructure, capable of providing services including highly accurate location, velocity measuring, and time transmission, and bringing enormous benifits in society and economy.

卫星导航系统是重要的空间基础设施，可提供高精度的定位、测速和授时服务，能带来巨大的社会和经济效益。

设计铂热电阻恒流激励测温的最佳非线性补偿变送电路，同时利用半导体致冷器件即可加热又可致冷的双向特性，制成以半导体致冷器为冷/热源的高精度控温系统，在20~40℃，控温精度高达±0。

In critical situations such as reference node failure, unstable radio transmission range and beacon collision, our algorithm performs well. We believe that this algorithm is suitable for sensor network.

根据模拟结果显示，我们的方法相较於单一讯号强度方法可提供较好的准确度，且这个方法在讯号传输距离不稳定、讯号碰撞以及随机散布等状况下皆有不错的表现，相当适合运用在感测式网路环境中。

Today, such patrol aircraft have radars that can pick up a schnorkel mast, although other ships have a harder time spotting the mast than they would the surfaced sub.

现在，虽然有其他的船更加难以探测到上浮潜艇的schnorkel桅杆，但有些巡逻飞机装备了可侦测到schnorkel的设备。

In this paper an order tracking technique and double threshold trigger technique are developed to ensure the synchronous data acquisition and to eliminate the disturbance and noise in rocket speed signal.

由此可保证各倍频分量幅值的精度，减少频率泄漏，同时保证了各帧数据具有相同的相位基准。同步、同相基整周期采集需由转速信号触发采集来实现。一般情况下，涡轮泵转子上的测速盘为多齿盘。
