Of 30,000 known Ascomycetes only 5,000 have been 'connected' to their anamorphs - results often 'messy' eg teleomorph genera, Nectria and Gibberella, both have anamorphs which have been classified in the anamorph genus Fusarium Many anamorphs (85%) have no known teleomorph - are termed Deuteromycetes.

有时将有性与无性联系容易，许多情况下难甚至做不到，因为有的菌丧失了有性生殖的能力。30 000种已知的子囊菌只有5 000种与无性态挂上了勾，结果往往是杂乱的，如有性阶段的丛剌壳属和赤霉属的无性阶段都是镰霉属。

So the optimum treating temperature to bivoltine races was from 44～46℃. When unfertilized eggs were treated with hot water for 3～68 minutes, asexual developed eggs could be obtained. But the optimum soaking time range to bivoltine races was 14～ 16 minutes.

针对我国的二化性家蚕现行品种，其无性繁殖诱导温度以44℃~46℃为宜；无性繁殖的处理时间适应范围较广，从3min~68min都可获得一定比例的无性繁殖发育卵，我国的二化性家蚕现行品种，其无性繁殖处理时间以14~16min为宜。

The asexual reproductive eggs and larvae were obtained when 50 commercial and bivoltine races induced by hot water. But the rate of asexual developed eggs varied markedly among these races, the range was 11. 99～88. 88 percent. About one-third races, their rates of asexual developed eggs attained 70～80 percent. The rate of asexual developed eggs about hybrid was higher than its parent.

对我国50个二化性现行品种资源进行无性繁殖发生率调查，结果表明各品种都可经诱导获得一定比例的无性繁殖发育卵和幼虫，但品种间存在较大差异，其发生率范围在11.99~88.88%之间，有1/3品种的无性繁殖发生率达到70~80%，而杂交种的无性繁殖发生率明显超过原种的水平。

In this study, nine aspects had been carried out, which included the condition optimization of inducing silkworm asexual reproduction; the effective technique of obtaining unfertilized eggs from virginal moth; the investigation of asexual reproductive genetic resources on bivoltine silkworm races; the creating of bivoltine female asexual reproductive lines; the genetic effect analysis of silkworm asexual reproductive character; the eggs protein study on different female lines; growing and developing comparison between asexual reproductive line and its sexual parent; RAPD study on asexual reproductive character; the utilization of asexual reproductive lines.

本论文主要研究内容包括：家蚕无性繁殖诱导条件的优化；从家蚕处女蛾获取未受精卵的实用技术研究；二化性家蚕品种无性繁殖特性的遗传资源调查；二化性雌蚕无性繁殖系的构建；家蚕无性繁殖性状的遗传效应分析；家蚕无性繁殖品种的蛋白质研究；家蚕无性繁殖品种与其两性亲本生长发育对比研究；控制家蚕无性繁殖性状的基因的RAPD分子标记探索以及家蚕无性繁殖系的利用研究等九个方面，取得的主要结果如下

Seveteen fine biovotine female lines also had been bred out after 5～10 generations selecting directly to the bivoltine genetic resources, which included 8 Chinese female lines, 8 Japanese female lines and 2 hybrid female lines. These female lines could be reproduced easily by asexual reproductive way, their rate of asexual developed eggs were high with only female generations and economic characters were also stability.

采取直接利用无性繁殖性状较优良的二化性现行品种资源构建雌蚕无性繁殖系的方法，经5~10代的无性繁殖继代选择，初步育成了17个雌蚕无性繁殖品系，其中中系品种8个，日系品种7个，杂交种2个。

Megaspore development and abortion of"Pingyi Tiancha"Compar-ing with regular developing megaspore of normal M.baccata,the megasporemother cellof"Pingyi Tiancha"could form mono-nucleus embryo sacby perhaps irregular meiosis,then most of sexual MES depauperatedand degenerated,finally aborted,or only a few further developed.Of asexualembryo sac,one or more large cells at the chalazal end of nucellus developed in-to one to more asexual embryo sac initials.After the competition between sexu-al embryo sacand asexual embryosac,most ovules only had one asexual embryo sac matured.

平邑甜茶大孢子的发育和败育与正常发育的山定子大孢子对比，平邑甜茶大孢子母细胞经减数分裂能形成单核胚囊，之后多数有性胚囊萎缩、退化而败育，只有极少数进一步发育；而无性胚囊则从胚珠合点端1个或多个较大的珠心细脆形成并首先发育为一个或多个无性胚囊原始体；经过有性胚囊和无性胚囊以及无性胚囊和无性胚囊之间的竞争，多数胚珠只有一个无性胚囊成熟。

In some cases it has been possible to 'connect' the anamorph name with the teleomorph name - but in many others this has not yet been done and may never be possible because the organism may have lost the ability to reproduce sexually.eg teleomorph genera, Nectria and Gibberella, both have anamorphs which have been classified in the anamorph genus Fusarium

The age class structure of Salix oritrepha population in alpine, cloudy and wet area of east Qilian Mountian is studied ,on two levels of genets and their ramets and sprouting branches .The results show that genets population is very short of the first and second class seedlings,and most of seedlings belong to the third and forth classes, and the development trend of population on this level is stable;on the other hand,the age structure of remets and sprouting branches population is more complete,and its age class distribution chart likes triangle, belonging to increasing type.In general,Salix oritrepha population in this area is increasing, but its reproduct way have changed in community succession process in order to accommodate varying circumstances.

从无性基株个体种群和无性克隆分株及萌生枝种群两个层次上对东祁连山高寒阴湿地区山生柳种群年龄结构进行分析，结果表明：无性基株个体种群 0~10 龄级幼苗贮备严重不足，11~20 龄级苗木所占比重最大，种群动态呈稳定型；无性克隆分株和萌生枝种群年龄结构比较完整，结构分布图呈正三角形，种群动态表现为增长型；总体上来讲山生柳种群呈增长趋势，只是在演替过程中为适应环境其繁殖方式有所改变，导致现阶段山生柳种群两个层次结构状态。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
