SiO〓 crystal transformation was improved by adding Na〓SO〓, alpha cristobalite but not tridymite was catalytic active support. C〓 selectivity was improved by adding W and P, and suppressed deep oxidation property of SiO〓. W-O in catalyst surface was not active species. The support combined with S, W, P show low activity and high C〓 selectivity.

Na〓SO〓的加入促进了SiO〓晶型的转化，α-方石英是催化活性载体成分，而鳞石英没有甲烷氧化偶联反应活性。W和P的加入改善了C〓烃的选择性，抑制了SiO〓的深度氧化特性；W-O物种不是催化活性物种；由S、W、P及SiO〓组成的载体反应活性较差，但选择性较好；同时S元素对C〓烃的选择性的贡献有限。

On the silicon substrate an epitomical layer is made,where IC components are formed subsequently.In an CVDprocess,the silicon substrates places in a vacuum crystal tube are first heated to 1,600°C by high-frequency radio power and then H⒉Cl⒉Si and certain gaseous compounds of As or P is injected into the tube to make a deposit of several um on their surface.Ions of As or P are impurity deliberately added to the singl-crystalline silicon structure to supply electrons that transmit "negative"current in the silicon crystals,which is called n-type silicon.Bcan be added as impurity to produce p-type silicon that supplies holes for transmitting "positive"current.Whether a p--type of an n-type silicon substrate is needed depends on what type of transistors is expected to be manufactured on it:n-p-n type of p-n-p type

For example, the object is composed of four blocks, i.e. block A, B, C, D. Block A locates the left of block B and above block C. According to order, its code is ABDC etc. This code does not change its order after the object rotates, zoom, downsizes. The disadvantage of this method is that it will lose the target when the color is changed.A video fluid is composed of compressed data which include I, P and B(bi-prediction) frame. The data of each block of P frame is predicted by motion prediction and compensation from the data and motion vector of I frame.

MPEG视频流由I、P、B组成，为减少空间、时间的冗余，P帧的数据来自已经解压缩的I帧和P帧，B帧的数据来自已经解压缩的I帧和P帧或者P帧和P帧，这些需要解码的图像通过运动预测和补偿对P帧／B帧进行解码，P帧／B帧中每一个宏块的数据来自于最佳匹配的相应I帧和P帧或者P帧和P帧中，以及图像变化而必须的运动补偿。

The LCS of combination of prior 24 h incubation G-CSF and Ara-C was lower than using Ara-C alone (P.05). The inhibition of FLAG to LCS of HL-60 was higher than that of the combination of Flu and Ara-C (P0.05). With HL-60 cells pre-exposure to G-CSF before FA resulted in increase of cytotoxicity.

At the same time, most WDR neurons failedto respond to the light brush applied to the receptive fields, but they couldbe intensively excited by the noxious pinch.(5) The latency of the latedischarges was shortened from 118.83 ± 3.67ms to 50.72 ± 1.36ms (n〓32, P〓0. 01).(6) Preceding graded number of A〓fiber conditioning inputs (〓mA, 100 μs) delayed the C-activity evoked by the following nociceptive teststimulus activating both A- and C-fiber applied to the sciatic nerve. The latedischarges decreased from 9.29 ± 0.97 to 6.71 ± 0.68 with the A-fiberconditioning stimulus increasing from 1 to 5 (n〓8, P〓0. 05).(7) The intervalbetween the conditioning stimulus and test stimulus (C-T interval) wasincreasing, the inhibition tended to plateau off. At shorter time intervalsthe inhibition became more effective. When C-T interval was limited in 50ms,the inhibitory effects was the strongest, here, the late discharges reducedfrom 12.57±1.21to 2.29±0.42 (n=11, P＜0. 01).(8) Behavior research showedthat the rat model of snake venom exhibited neuropathic pain with heathyperalgesia, cold and mechanical allodynia, which corresponding to the acuteelectrophysiological findings.
