玉米淀粉和马铃薯淀粉分别在 35℃条件下用浓度为 2 。4 mol/ L的 HCl处理不同时间，采用 X射线衍射分析、差热分析和扫描电镜等测试方法对酸解后的淀粉颗粒进行结构和性能分析。

L〓 can accept the electron from the active PS Ⅱ center completely, and that DCBQ can only accept a part of the electron from the inactive PS Ⅱ center (40%) even at the concentration 120μ mol.

但DCBQ的浓度在比Cao等几乎高出一个数量级（120μmol.L〓）的情况下，也只接受部分无活性PS Ⅱ中心的电子（40％）。

After four months of observation of the growth season, the author reveals in the thesis the day- and month-dynamic characteristics of the net photosynthetic rate of Dahurian Larches, which are of different ages, densities and stand classes. The author also compared the net photosynthetic rates of the leaves on different-age braches and with the crowns of different layers and directions. In addition, the author analyzed the effects of some ecological factors on net photosynthetic rate as well.

通过生长季节四个月的定株观测，揭示兴安落叶松的光合特征，即不同年龄、密度、分级木净光合速率的日动态和月动态特征，比较树冠不同层次、不同方向和不同枝龄上针叶的净光合速率的日动态和月动态特征，分析光照强度、温度、CO2浓度等生态因子对兴安落叶松净光合速率的影响。

Turfgrass seeds of nineteen varieties were treated with the different Pb2+ concentrations of 0, 200, 400, 600mg/L, and germination potential, germination rate, root length, shoot length, fresh weight, chlorophyll content, MDA content of seedlings were determined to compare theirs lead tolerance.

用浓度分别为0、200、400、600mg/L的Pb2+分别处理19个品种草坪草的种子，测定了供试种子发芽势、发芽率、幼苗根长、苗长、鲜重、叶绿素含量、丙二醛含量等7项指标，比较19个品种草坪草生长初期耐铅性的强弱。

The last test is this: some "VIPs" sitting in木板凳dressed in Lederhosen, and then began to drink fresh beer, and sit in the bench for half an hour, when they stand up, wood must be able to close their Lederhosen, beer before that really passed the test, or that the concentration of this beer is too low, they are not eligible to become "real lent diet beer."

过去的测试是这样的∶一些&达官贵人&身着皮裤坐在木板凳上，然后开始畅饮新鲜啤酒，并在凳子上坐半个小时，等他们起身时，木板必须能够贴着他们的皮裤，才表示啤酒真正通过了测试，不然就表示这种啤酒浓度太低，没有资格成为&真正的四旬斋啤酒&。

The scattering spectra of this system were measured using an ordinary spectrofluorophotometer. Influence of experimental conditions, such as pH, ionic strength, and concentration of CAS, on the intensity of light-scattering was studied. Effects of surfactants (cationic, anionic, and nonionic), amino acids, and metal ions on the combination of CAS with protein were also investigated.
