Systematically analysing the method on the failure approach of patten recognition of the flood control hydro-project system, combining the social economical efficiency of the flood control system"s invalidation losses, the paper provides the concept "flood disaster risk " and constitutes the failure analysis approach of patten recognition system on the base of the flood progress. Combining with the subsystem functions and the failure probabilistic analysis of the hydro structure, the paper discusses the main failure approach of patten recognition and calculus of failure probability, calculates flood control hydro-project"s total risk.

The excellent agreements between simulated and measured results prove the accuracy of the established circuit model. Moreover, the varactor was added to the resonator to adjust its resonant frequency. As expected, the reactance introduced by the varactor indeed affects the net inductance and capacitance obviously. It is noted that, not only the shift with the center frequency, the inductive or capacitive of the reactance can also provide a parameter to switch its frequency toward the two directions away from the one without varactor. As a consequence, a wideband tunable band-pass filter is achieved. Although the bad quality factor with the diode strongly increases the insertion loss, this concept was proved to be available for effectively tuning the center frequency of such a class of band-pass filter.

另外，在共振器上的varactor是用来调整共振器的共振频率，如预期的，由varactor所造成的电抗确实的影响到共振器的总电感和电容值，值得一提的是，不仅滤波器的中心频率可以被改变，这电抗是电感性或是电容性也将决定滤波器的中心频率将大於或小於未加varactor时滤波器的中心频率，利用这个结果，我们也实现了一个宽的可调频率带通滤波器，虽然不理想之二极体的Q值增加了滤波器的介入损失，但这原理是被证明可有效的用於调变带通滤波器的中心频率。

结果表明：赖草株高45~120 cm，单生或丛生，具下伸土壤30~50 cm耕层间有横走根群，每平方米内，深50 cm耕层内赖草根茎总重量为1129.3 g，根茎总长度为2783.3 cm，根茎上的新芽589.7个，使土壤严重缺水，肥力下降；土壤水分在13.4%左右时，对出苗影响不大，对生长发育有很大的影响；气温在-6~6℃，根茎萌发出土，高峰期为4月上旬，平均单株结种量为468.4粒；每平方米内有赖草120~160株时，大黄产量损失达15.8%~17.8%；田间每平方米内有赖草1株时，采用人工或机械深耕捡出地下根茎，减轻翌年危害来源。

Results showed that all the three sweet sorghum varieties contained plentiful sugar, which can provide enough carbon source for alcohol fermentation, however, total nitrogen and some mineral elements（Fe3＋）cannot meet the needs of alcohol fermentation. Activity of most microbes in stalk juice can be inhibited and the sugar can be maintained when the stalk juice was condensed to 4～5 times. Due to the reasons that the activity of acetous microbe or hydrolysis enzyme inside stalk juice can be maintained, ratio of reducing sugar to total sugar was increased with storage time at 55～60℃,0.15 MPa vacuum condensed condition, which can be beneficial for the purpose of alcohol fermentation.

结果表明，三个品种都含有丰富的糖分，可以为酵母菌发酵制取酒精提供良好的碳源，但总氮和某些矿物质元素（如：Fe3＋）不能满足酒精酵母的营养需要；甜高粱茎秆汁浓缩至4～5倍时，可以抑制汁液中大多数微生物的活动，使其中糖分不受损失；在试验设定的真空浓缩工艺条件下（55～60℃，0.15 MPa）甜高粱茎秆汁中产酸微生物或水解酶类仍保持活性，使得还原糖占总糖的比率随贮藏时间延长而升高，这有利于酒精发酵。

It is indicated that this loss will not change with the increase of the Reynolds number but the intensity of the passage vortex increases with the decrease of the Reynolds number. The tip leakage flow will weaken with the increase of the passage vortex because of the interaction between the passage vortex and the tip leakage vortex, and the position of the tip leakage vortex is more close to the middle of the passage. In addition, the distributions of the total pressure loss and the flow angle at the exit of the cascade are influenced by the intensity and the position of the tip leakage vortex.
