The microspore was more like a tetrahedron, whilethe polar was more like a triangle. The number of microspore in every anther wasbetween 2600~3600, so the amount of pollen was quite large that it was propitiousto spread and pollination. P/O was 8088 and the breed system was singleheterosexual copulatoryb. The viability of pollen was normally above 50%. The testof pollen culture showed that the viability of pollen was up to the tiptop under thehigher temperature and lower humidity (38℃,40%),while it was weakest under thelower temperature and lower humidity (16℃,40%).The OCI is 4, and the breedsystem was belong to autocopulation. If it was heterosexual copulatory, there must beintermediums for pollination. It was recorded there were more than 40 species ofinsects on the anthotaxy or followers of Malania Oleifera. Under different weather,different living environments and different plants the frequency and rush hour of theinsects to visit the followers were different. Actions of different kinds of insect werealso different. According to the results of the observation, the form of fluid and seedof Malania Oleifera mostly rely on the action of insect pollination, especially thebees.

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。

The average percent value of G C (49.3%) was less than that of A T (50.7%), there was a bias of the content of G, T in the third codon; The number of transition G-A and T-C were 22, 15 respectively, which were higher than that of transition A-G and C-T, the number of tranversion C-A, T-G is 2 respectively, and other tranversion patterns didnt occur; the probability of transition was higher than that of tranversion , Ts/Tv = 9.5-19, there was the highest number of transition in the third codon. The gamma parameter a of the lst,nd and 3rd codon positions were 0.00572,0.01237 and 1.05239 respectively, they showed that there was adifferent substitution rate at different codon position. Frequences of synonymous codon usage were relatively biased. The average rates of synonymous and nonsynonymous substitution were 0.0787, 0.0011 respectively, there was a significant difference between dS and dN (Z = 4.713, p.01), and the low ratio( CD = 0.0284 .3) of dN/dS ratio impled that there were selective constraints against the nonsynonymous sites in cyt-b gene, The distribution of nonsynonymous codon substitution pattern related to Grantharm distance indicated that the purified selection at 2nd codon positions was more intensive than that at 1st codon positions. The phylogenetic trees supported the view of the double origin of Chinese goose, which means that domestic Chinese goose was derived from Anser cygnoides and domestic European goose, and Yili was derived from Anser anser.

碱基含量分析可知,序列的G C含量(49.3%)<A T含量(50.7%),密码子第三位点的G、T含量都有较强的偏倚性;序列间G→A和T→C的转换数(22次和15次)高于A→G和C→T的转换数(10次和9次),C→A、T→G颠换数均为2次,其余颠换模式均未发生;转换数明显高于颠换数,Ts/Tv=9.5~19,密码子第三位点的转换数最高,呈现了相当强烈的转换偏倚性;密码子第一、二和三位点的gamma分布参数α值分别为0.00572、0.01237和1.05239,表明密码子第一位点的替换速率变异最大,第二位点次之,第三位点的替换速率变异相对较小;编码同一氨基酸的同义密码子并非随机使用,表现出一定程度的使用偏倚性;同义替换速率和非同义替换速率分别为0.0787和0.0011,dS与dN值间的差异极显著(Z=4.713,p<0.01),而ω=0.0284,明显小于0.3,表明雁属鹅细胞色素b基因序列经历了中度净化选择作用;单步非同义替换(Sing-step nonsymonymous codon substitution,SSNCS)分布模式与Grantharm距离之间的关系说明密码子的三个位点所受的净化选择强度不同;构建的最大简约树与邻接树拓扑结构一致,支持中国家鹅的双起源学说,即除伊犁鹅外的其它中国鹅品种起源于鸿雁,伊犁鹅和欧洲的郎德鹅、莱茵鹅起源于灰雁。
