The results showed that the MS2 fragmentation pathways of DASSSB were affected by the character and position of substitutes on salicylidene phenyl. The C=N cleaving to form fragmentation ion [M+H-283](superscript +) was dominant for DASSSB compounds with electron-donating group on the C4 of the salicylidene phenyl; while fragmentation ion [M+H-254] (superscript +) forming by C-C cleavage of the β-position of C=N was dominant for DASSSB compounds with electron-withdrawing group on the C5 of the salicylidene phenyl.

结果显示，这些化合物的ESI-MS/MS裂解方式与它们分子中水杨醛苯环上取代基的性质和位置有关：当水杨醛苯环上4位连接供电子取代基时，分子以CN双键断裂为主，生成[M+H-283]碎片离子；当水杨醛苯环上5位连接吸电子取代基时，分子以CN双键β位的C-C键发生断裂为主，生成[M+H-254]碎片离子。

For a futher research on the natural gas and minimizing the detector,we measured the spectrum lines which may affect the detection of CH4 near 1.65μm and 1.68 μm accurately by using the TDLAS theory.Then we set up an sinal acquiring and processing system based on LABVIEW,which can aquire and filter the digital signal and an interfix arithmetic is also used to get the final result.

本论文以近红外二极管激光吸收光谱技术为基础，在1.65μm和1.68μm附近对乙烷的谱线进行了准确测量，分析了乙烷谱线对甲烷测量的影响，编写了基于LabVIEW的数据采集及处理分析系统，利用该系统实现了对探测信号的采集、滤波以及对波形的相关运算并得出最终结果。

To understand more about the relationship of SOCE with lipid raft,we have studied the influence in cell polarity by mβCD,mβCD can clear the cholesterol of membrane to destroy the integrality of lipid raft.

为了进一步理解SOCE和脂筏的关系，我们观察了mβCD(甲基-β-环糊精，Methyl-β-cyclodextrin)对中性粒细胞极性的影响。mβCD能够清空中性粒细胞胆固醇，破坏脂筏完整性，从而可能影响到极性的形成过程。

It can be seen that the size of the microgels is around 50～60 nm in diameter in the solid state,and the microgels exhibit a narrow size distribution with an average diameter of around 100 nm in the wet state.2.Pore size and morphology of hydrogelThe SEM images of freeze-dried hydrogels exhibited a highly macroporous spongelike structure and the average mesh size is about 10μm.

孔径通过扫描电子显微镜可以看到凝胶内部呈现多孔的类似海绵内部的结构，孔径在10μm左右，浸泡24h后可以发现网络结构发生了降解，孔径变大，达到20μm左右，浸泡7d后凝胶进一步降解，孔径增大到40～50μm.3。

Under the optimum conditions of n: n=40, mass percentage of ZrO2 18%, temperature 400℃, m m=0.02 and reaction time 0.5 h, the conversion was 91.2% and the yield of liquid products was 83.6%. Compared with the results obtained by thermal pyrolysis and catalytic pyrolysis on HZSM-5, ZrO2/Ti-MCM-41 was of better catalytic activity and higher yield of liquid products, and was especially suitable for the pyrolysis of sterically hindered polymers such as PP.

结果表明，n：n=40，ZrO2负载质量分数为18%的ZrO2/Ti-MCM-41，在反应温度400℃，m(ZrO2/Ti-MCM-41)：m=0.02，反应时间30min的条件下，PP的转化率可达91.2%，液体产物的收率为83.6%，该结果优于热裂解及传统的HZSM-5小孔分子筛催化剂的催化裂解结果。

The results showed that the light saturation point of potato leaf was about 1400 μmoll(m^2s) and its light compensation point was about 50 μmoll(m^2s), the stomatic conductance and the transpiration rate increased while the intercellular CO2 concentration reduced with the increasing of light intensity between the light compensation point and light saturation point.

试验结果表明：马铃薯叶片光合作用的光饱和点约为1400 μmol/(m^2s)，光补偿点约为50μmol/(m^2s)。在光饱和点和光补偿点之间，随著光合强度的增加，叶片的气孔导度和蒸腾速率升高，胞间CO2浓度降低；随著CO2浓度的增加，光合速率升高，其CO2的饱和点约为2000μmol/mol。

Aschersonia blumenaviensis was originally described from Brazil, it may be confused with Aschersonia flavocitrina by sharing same stromatic color (lemon-yellow), however, the latter species has larger spores (12–18 × 2μm) and longer paraphyses (140–180μm).

布鲁门拿维安座壳孢最初在巴西描述，与Aschersonia flavocitrina的子座均为柠檬黄而易混淆，但是后者有更大的孢子（12–18 × 2μm）和更长的侧丝（140-180μm）。
