P. denasta harbored the three chlorotypes, two of which were characteristic of its two parental species respectively. The third chlorotype was extensively distributed in seven of the ten P. densata populations analyzed, and might represent a mutation type or have been derived from an extinct parent. Population differentiation of P.

TT和GC分别是油松和云南松种特异性叶绿体单倍型，而在高山松群体里则三种单倍型均有分布，而且TC单倍型广泛地分布在7个杂种群体中，该单倍型很可能来源于点突变或第三个已灭绝的亲本。rbcL基因检测到的高山松群体分化系数很高（G〓=0.533）。

This paper presents a review of studies of interference absorbing materials,which come in three basic types:normal interference absorber,Jauman absorber and FSS absorber. And we particularize the structures,applications and methods of analysis and design of each of these types. Results show that the FSS absorber provides a better absorption ability and is more practicable,and that active multi-layer FSS absorber represents a new direction of interference absorbing material research.

综合介绍了干涉型多层吸波材料的吸波原理及其国内外研究现状，并分别研究了干涉型多层吸波材料三种基本类型：一般干涉型吸波材料、Jauman吸收体和频率选择表面吸收体的一般结构、应用以及分析与设计方法，得出FSS吸收体较之其他类型具有更优的吸收性能和更高的实用价值，最后指出了干涉型吸波材料发展的新方向是有源FSS吸收体。

综合介绍了干涉型多层吸波材料的吸波原理及其国内外研究现状，并分别研究了干涉型多层吸波材料三种基本类型：一般干步型吸波材料、Jauman吸收体和频率选择表面吸收体的一般结构、应用以及分析与设计方法，得出FSS吸收体较之其他类型具有更优的吸收性能和更高的实用价位，最后指出了干涉型吸波材料发展的新方向是有源FSS吸收体。

But it's the overall lack of visibility that has left analysts penciling in anything from 'W' to 'L' shaped recoveries, to a rather more optimistic 'U' or 'V'.

不过，总体透明度的不足令分析师莫衷一是，既有"W"型和"L"型的复苏，也有更为乐观的"U"型或"V"型的反转。

Gold ore deposits mainly occur in carbonaceou s phyllite, clastic rock and sericite-quartz schist and are controlled by ducti le shearing zone and tectonic alteration zone.

铜矿化与华力西期花岗岩类关系较紧密，金铜找矿以海相喷流沉积型铜矿、斑岩及夕卡岩型铜金矿、构造蚀变岩型金矿及韧性剪切带型金矿为主。

The incidence rates of high jugular bulb in petrous apex pneumatolysis I and III were 31.25% and 30.58%,and 31.64% and 29.02% in processus mastoideus pneumatic type and other types, with no significant difference.

岩尖气化I型与III型颈静脉球高位的发生率分别为31.25%及30.58%，乳突气化型与其它型颈静脉球高位的出现率分别为31.64%及29.02%，差别均不存在统计学意义。

In the biotechnology area, we has set up polytype Handson yeast express system which owned freedom intellectual property rights, including:(1) URA3 - defective nutrition host cell strain HU-II;(2) secretion and intracellylar expressing plasmid carrier pMPT-01、pMPT-02;(3) a platform for semi-works

在生物技术领域：建立了拥有自主知识产权、较为完善的多型汉逊酵母表达系统，包括：（1）URA3 -营养缺陷型宿主细胞株HU-II；（2）分泌型和胞内型表达质粒载体pMPT-01、pMPT-02；（3）汉逊酵母细胞电穿孔转化操作程序及多拷贝、稳定化整合转化子筛选程序；（4）中试生产规模的发酵和纯化平台。

INVESTMENT MANAGERS CLASSIFY FIRMS that have high ratios of book-to-market equity, earnings to price, or cash flow to price as value stocks. Fama and French (1992,1996) and Lakonishok, Shleifer, and Vishny (1994) show that for U.S. stocks there is a strong value premium in average returns.

本研究对价值型个股与成长型个股的区别方式是透过 INVESTMENT MANAGERS CLASSIFY FIRMS 的定义，以股价净值比、本益比、或现金流量对价格比中，较低的个股定义为价值型个股，较高的则定义为成长型个股。

The degree of integration had positive relations with the degree of career development, however, the conflict ratio had negative relations with the degree of career development, and the degree of differentiation had inconsistent relations with the degree of career development; in study two, the Primitivity type held lower degree of career development and the Control type possessed higher degree of career development as predicted by the theory, while the other types were somewhat vague in between.

建构系统之统整性与生涯感受、生涯信念、生涯认识、思考广度与生涯计画等变项呈现出同方向的互动关系，而冲突性则与上述变项有反向的关系，分化性与生涯发展程度的关系则较不一致。质化资料分析结果亦显示出在生涯建构系统两极端之原初型与笃行型有较明显的生涯发展特徵，前者的发展程度偏低，后者则偏高，但处於两极端中间之慎思型与明辨型的生涯发展程度较为混淆不清。

The 6 AChE Genes from L.bostrychophila,L.entomophila and L.decolor were demarcated into Insect TypeⅠAChE Gene and Insect TypeⅡAChE Gene.4 Gene cloning of nAChR and mRNA expression level in L.bostrychophilaTwo nicotinic acetylcholine receptor subunit genes,Lb al and Lb a8,were cloned from the psocid L.bostrychophila.The full length cDNAs of Lb a1(GenBank Accession No.: EU871527) and Lb a8GenBank Accession No.

昆虫的两类AChE严格的区分，其中Ⅰ型AChE先与脊椎动物AChE聚合后才与Ⅱ型AChE相聚，说明两类AChE基因在物种分化前就已经分化。4嗜卷书虱烟碱型乙酰胆碱受体基因克隆及其mRNA表达水平研究利用RT-PCR和RACE技术成功克隆获得了嗜卷书虱2个烟碱型乙酰胆碱受体亚基的全长序列，分别命名为Lb a1(GenBank登录号：EU871527)和Lb a8(GenBank登录号：EU871526)。
