The decay of ~(99m)Tc source was used to verify experimentally that in the measurement of the number of atoms of a radioactive isotope in a sample at time t_0, the error introduced through the inaccuracy of its decay constant can be reduced to a much smaller value by the careful selection of the time of measurement or measurements of its radioactivity at around one life time (1/λ) after t_0 and doing the calculation.

本文用~(99m)Tc源的衰变实验证明了：在测量一个样品中在t_0时的一种放射性同位素的原子数时只需精心选择一次或多次测量其放射性的时刻在t_0后约该同位素的一个寿期(1/λ)，并进行计算，则由它的衰变常数或其半衰期(T1/2)的不准确性而引进的误差可以被降低到较小值。

Methods Animals were randomly and equally divided into five groups: saline control group, positive drug control group, low-dose, medium-dose and high-dose crocetin group. Animals were anesthetized with urethane (1.2 g/kg), then followed by the perfusion of aconitine (10 μg/mL) through caudal vein in rats, or of ouabain (9 μg/mL) through external jugular vain in guinea pigs in a constant velocity of 0.1 mL/min, and the emergence time of ventricular fibrillation, ventricular extrasystole, ventricular tachycanlia and cardiac arrest were then detected and recorded. The recorded time was then translated to the cumulated amount of aconitine and ouabain. Experimental arrhythmia was induced by rapid injection of 4% CaCl2 (140 mg/kg), and the emergence time, persistence time, incidence and death of arrhythmia after the administration were observed.

After that, the important equation for calculating reverberation time is given based on the definition of reverberation time and least squares method. Finally, we use our new method to calculate reverberation time in a rectangular enclosure; we also compare our results with those given by experiment and Sabine's equation. The comparison shows that the new method is more effective and accurate than Sabine's equation in calculating reverberation time of small enclosures.

But how will the computer + the human brain in this intelligent combination of dual-core functions, when the computer system failures as a result of the virus and slow down or even crash, most people can only wait anxiously for the experts, or home computer to be painstakingly maintenance stations for maintenance, because the traditional way to deal with this problem again when the need to use the CD-ROM system (often because the driver would also like to find lost disk driver), a number of computers equipped with the "one-click restore" feature or the current popular technologies only GHOST users can restore your computer to your computer at all times or do the factory GHOST time, and after they were unable to retrieve data, and in the time to do the reduction is due to the use of conventional disk copy, the whole is a long time.

但如何将电脑+人脑这智能的双核功能结合在一起，当计算机由于系统故障、感染病毒而变慢甚至死机时，大多数人只能焦急地等待专家上门或费尽周折将电脑送到维修站进行维修，由于传统方式处理这种问题时需要使用光盘重做系统（常常会因为驱动盘丢失还要找驱动程序），许多电脑配备的"一键还原"功能或目前流行的GHOST技术仅仅可以将用户电脑还原到电脑出厂时刻或做GHOST时刻状态，之后的数据它们是无法找回的，而且在做这些还原的时候由于采用的是常规的磁盘拷贝技术，整个时间也是比较长的。

This dissertation was focused on the research about the formation and evolution of NQB from the Late Triassic to the early middle Epoch of Jurassic Period, including integrated analyzing the characteristic of the key stratigraphic surfaces, the time of the key stratigraphy, regional rock straigraphy, biostratigraphy and chronostratigraphy, sedimentary system and depositional facies. On basis of these analysis, a tectonic evolution model have been established for NQB during from the Late Triassic to the early middle Epoch of Jurassic Period.1. After the systematic surface analysis about main stratigraphy units, we found that:(1) the bottom of Xiaochaka formation was comformity with the middle Triassic in the basin, and in the north margin it was deposited and overlapped on the different period stratigraphy before Triassic.(2) The top surface of Xiaochaka formation developed regionally karst and paleo-karst breccia, and was uncomformity with Nadigangri Formation, these things suggest that NQB in Xiaochaka depositing stage was developed from middle Triassic basin, and then an extensive regression occurred, the deposition was over and erosion come into being.(3) The lithologic assemblage, geochemistry, mixed fossils, and stratigraphy overlapping characteristic of Quemocuo Formation in early middle Jurassic indicted that the uncomformity surface was an extension-unconformity.2. Integrated analysis about stratigraphy division and correlation indicted that:(1) the paleontologic assemblage of Xiaochaka formation show its time was Carian -Norian stage of late Triassic. According to it was overlapped by late Triassic Nadigangri Formation, so Xiaochaka formation should be Carian - early Norian stage.(2) the SHRIMP Zircon U-Pb age of Nadigangri formation volcanic rocks wear vary form 216 to 205 Ma, so its time should be Norian, but maybe extended into Rhaetian Stage.(3) The age of its bottom volcanic rocks, the fossil assemblages of its middle and upper members and overlapped by lower Jurassic, indicted the age of Riganpeicuo Formation was Norian - Rhaetian stage. And the same time, the volcanic rocks geochemistry of Nadigangri and Riganpeicuo formation both reflected that they wear formed in rift tectonic settings. The lower lithologic and surface characteristic, fossil assemblages and its upper maybe was conformity with lower Jurassic, all reflected that the age of Tumengela Formation in Tumen area should be Norian - Rhaetian stage.

The major findings are:⑴During the intelligence test for the three groups of students, for half of the students or most of the students their scores on the all-including scale, the language scale and the performance scale all increased to various degrees;⑵From the analysis of the relationship between intelligence and reaction time, it is found that the result of this study confirms the existing views that there is a negative correlation between intelligence and reaction time, and the negative correlation is more evident when it is choice reaction time;⑶Different motor skills have different influences upon children with lower intelligence. Though the difference is not large, the average increasing percentages in the sample T tests for the three groups before and after the experiment show that the effect of open motor skill is the best, that of the synthetic motor skill or the open-closed is the better, and that there isn't a marked change in the closed motor skill trainees;⑷While analyzing the result of the experiment, it is found that the scores on the performance scale are higher than the scores on the language scale, especially in the open motor skill group, which tells us that the intelligence improving effect of physical training is realized to a greater extent through increasing their performance abililty.

研究结果显示：⑴相对于实验前测试结果，三个实验组学生的智力水平在实验后测试中不论是在全量表得分还是在语言量表、操作量表得分方面均得到了不同程度的提高；⑵从智力与反应时的相关分析可看出，本研究结果进一步验证了前人观点，即智力与反应时有显著的负相关，特别是与选择反应时有很强的负相关性；⑶不同运动技能对智力落后学生智力影响不同，虽然实验后各组间没有显著性差异，但经各组实验前后配对样本T检验及实验前后各项分数均值提高百分率可看出，开放式运动技能组实验效果最好，综合运动技能组次之，闭锁式运动技能组实验前后在智力测验量表得分上无显著性变化；⑷各组实验前后的操作量表分比言语量表分提高幅度更大，开放式运动技能组表现得尤其显著，这表明了体育活动对改善智力落后学生的智力水平，很大程度上是通过提高他们的操作能力来实现的。

Small time I lively active, has filled curiously to the new things, time takes to the streets with mother does grocery shopping, I first time see to have two big pliers, eight legs biology, I make mother to call her to buy to me, afterwards I like was willing to obtain it, after went home I to be very happy raises it in the keg, I put out a hand to trace its big pliers, the crab also gratefully face my hand maliciously to clamp, my pain 哇哇大哭, afterwards was at that time the daddy takes the fruit jelly I only then not to cry to me.
