A new control strategy for three-phase grid-connected inverter（GCI） of photovoltaic generation system（PVGS） with LCL filter is proposed. Based on the non-linear 3rd-order model of the inverter, the robust active disturbance rejection control（ADRC）, which is composed by the cascaded tracking differentiators（TD）, the 4th-order extended state observer（ESO）, the non-linear PID（NLPID） and the disturbance compensating is designed to enhance the steady and dynamic performances of the PVGS. Experiments on a 10 kW prototype are presented to verify the advantages of the proposed approach.

该研究利用离子色谱和高效液相色谱等方法,研究了中高温大曲不同发酵时期小麦营养成分的变化及其与微生物群落演替间关系。结果表明,曲皮和曲心分别消耗了直链淀粉含量的39.08%和49.12%,支链淀粉含量的84.43%和81.35%,A型淀粉粒的6.41%和26.92%,B型淀粉粒的66.67%和83.33%。麦谷蛋白含量从8 mg/g降为4.73 mg/g(曲皮)和3.53 mg/g(曲心)。黄酮含量从0.08 mg/g增加到0.12 mg/g(曲皮)和0.29 mg/g(曲心)。纤维素含量总体呈下降趋势,但曲心后期有平缓上升;阿拉伯糖和蔗糖含量增加,葡萄糖含量降低。曲心游离氨基酸含量增加幅度高于曲皮,其中谷氨酸含量最高。冗余分析表明18个品质指标与9个细菌属和11个真菌属的相对丰度显著相关(P<0.05),其中直链淀粉含量与叶杆菌属(Phyllobacterium),葡萄糖、果糖、支链淀粉含量与醋酸单胞菌属(Acetobacter)、双杆菌属(Undibacterium)、乳杆菌属(Lactobacillus)均显著正相关。因此,具有高支链淀粉和高葡萄糖含量的小麦品种可能更适用于制曲。该研究结果为探究大曲质量控制、小麦品质与大曲品质间关系,以及选育专用型原料(小麦)品种提供参考。

The squeeze casting of a 2024 Al alloy was carried out to investigate the effect on microsegregation in the alloy of the application of pressure followed by diffusion annealing. The experimental results indicate that an optimum applied pressure followed by an optimum diffusion annealing process can markedly reduce the degree of microsegregation and improve the mechanical properties to a degree that can approach the level of forged 2024 Al alloy.

目的研究苗药艾纳香的性状及显微特征,为其生药学鉴别提供理论依据。方法采用性状、显微鉴别法研究苗药艾纳香的生药学特性。结果艾纳香的叶中脉在上、下表面均凸起,侧脉10~15对,完整叶片展平后两侧有狭线形裂片;其中柱鞘纤维呈半圆形,常由6~10列厚壁细胞紧密结合。假东风草(滇桂艾纳香)两面无毛或被疏柔毛,中脉仅在下表面凸起,侧脉5~7对,两侧无狭线形裂片;其半圆形中柱鞘纤维仅由2~3列厚壁细胞组成,包裹整个韧皮部和木质部。假东风草维管束鞘呈半圆形,较艾纳香窄。艾纳香叶下表皮腺毛和非腺毛的长度及数量均较假东风草叶多,假东风草叶上表皮细胞略呈多角形,艾纳香叶上表皮由类长方形排列紧密的细胞组成,垂周壁较平直,较少气孔。两种基原药材的粉末无明显区别。结论艾纳香、假东风草两种基原植物在药材性状和显微特征方面均具有显著的形态学规律,对其作真伪鉴别具有实际意义,可以作为艾纳香药材鉴定的理论依据。
