整倍性

Complete resection of aneuploid leukoplakia does not reduce the high risk of aggressive carcinoma and death from oral cancer.

完全切除非整倍体白斑并不降低发生侵袭性肿瘤和口腔癌所致死亡的高度危险。

The rates of the heteroploidy and aneuploidy rose gradually in the shift of benign- borderline-malignancy, and the same was true for the rat es of mortality/relapse as well as the contrast risk. The nature of ovarian tumors with heteroploidy was much malignant than that with diploidy.

在良性、交界性至恶性肿瘤系列中，异倍体率或非整倍体率明显增加，病死和复发率及相对危险性随之增高；异倍体肿瘤的性质较恶，2倍体肿瘤趋于良性。

That PI and the percentage of the cells in s-phase of the borderline/malignant and heteroploid/aneuploid tumors were higher ted to higher mortality and relapse rate as well as the corresponding risk. Because of the changable characters and dissociative phenomenon of the tumor, the measurement of PI and the percentage of cells in s-phase may be disturbed in few of diploid tumor and in part of double DNA stem ones. Therefore other paramet- ers should be added to analyse before making any conclu- sion.

交界性和恶性、异倍体或非整倍体肿瘤的PI和S期细胞百分率较高，病死加复发率和相对危险性增加；由于肿瘤的异质性和"分离现象"，对于少数2倍体肿瘤和部分双DNA干系肿瘤PI和S期细胞百分率的测定易受干扰，故应结合其它参数综合分析。

By using two color FISH with one euchromosome probe and one sex chromosome probe, the sperm with same color of two hybridization signals in one sperm head could be identified as aneuploidy sperm or diploid sperm.

若用1条常染色体探针和1条性染色体探针进行FISH，可以区别头部有2个相同颜色荧光杂交信号的精子属非整倍体精子或二倍体精子。

The results indicated that the treatment of irradiation restrained the growth and differentiation of protocorm, especially to roots.The LD50 is 67.23Gy, because the protocorm is a integrate embryoids and higher tolerance was found. Ploidy analysis showed that most of aberrant seedlings go with the change of DNA and they were not euploid. When the plants trearted by irradiation, some of aberrant seedlings appeared stem forfication, and leaves appeared chlorophyll-deficient or green-white.,probably due to some genes' expression or closing.

结果表明：辐照处理对种胚原球茎的生长和分化有抑制作用，尤其是对根的抑制更为明显；由于种胚原球茎的完整性好，耐受性强，其辐照半致死剂量(LD50)为67.23Gy；流式细胞分析表明，大多数外部形态发生改变的植株其细胞内DNA的倍性发生了改变，出现相当多的非整倍体；此外，辐照产生的变异苗出现茎分叉、叶片缺绿或白绿相间等现象，可能是由于某些基因的表达与关闭引起的。

The results showed that the number of chromosome, which was from the cultured seedlings of meristem tip and the rank seedlings of meristem tip, was not altered, both the number were 2n=16,the hereditary stability of callus and regeneration plant was poor; and the variation percentage of chromosome in callus was 43.4%, among which haploid accounted for 6.7%, triploid accounted for 2.5%,tetraploid accounted for 10%,pentaploid accounted for 4.2%,hexaploid accounted for 3.3%,septuploid accounted for 4.2%,octoploid accounted for 3.3%,dysploid accounted for 9.2%;the chromosome variation percentage of differentiation seedlings derived from callus was11.7%,among which haploid was 6.7%,triploid accounted for 1.7%,tetraploid was 3.3%.

结果表明，茎尖分生组织培养的幼苗及丛生苗遗传稳定，其染色体未发生倍性变异，均为2n=16；愈伤组织及其再生苗遗传稳定性较差，愈伤组织染色体数变异率为43.4%，其中单倍体占6.7%、三倍体占2.5%、四倍体占10%、五倍体占4.2%、六倍体占3.3%、七倍体占4.2%、八倍体占3.3%、非整倍体占9.2%；愈伤组织分化苗染色体变异率为11.7%，其中单倍体占6.7%，三倍体占1.7%，四倍体占3.3%。

In the offsprings of the aneuploids (P3) with 41~44 chromosomes, there are four types of plants with 29~32 chromosomes. Except the plant with 29 chromosomes, others which appeared abnormal meiosis behavior and poor pollen fertility are mixoploid.

在染色体数为44与41的两种超倍体（P3群体）后代，鉴定出具有29~32条染色体的4种非整倍体，除染色体数为29的植株外，其余均为混倍体，它们的减数分裂异常，花粉育性低。

Recommended National Standards GB/T12243-2005 "spring load safety valve directly," provides a safety valve discharge pressure should not exceed 1.1 times the setting pressure or 1.2 times the setting pressure.

推荐性国家标准GB/T12243-2005《弹簧直接载荷式安全阀》规定，安全阀的排放压力应不超过1.1倍的整定压力或1.2倍的整定压力。

I this is at that time, the opinion with peacockish true girl is full of in a heart.
