And Changbai larch(Larix olgensis A.Henry)atdoubled CO2 concentration at seedling stage in growth-chamber and WI,HI of several dorminanttree species in MBKPF(1)Under 700μl·1-1 concentration of CO2,the stem height, stem diameter,main root length,root/shoot ratio and the relative proportions of biomass in root,stem and leaf of the seedlings ofKorean pine and Changbai larch had no significant change.

在700μL·L-1CO2条件下与正常浓度下相比较，在一个生长季后，红松、落叶松幼苗的苗高、地径、主根长、根茎比及生物量在根、茎、叶各器官中比例，差异不显著，对落叶松的侧枝数有影响；在第一、二次试验中，落叶松幼苗的平均每株生物量比在正常CO2浓度下大12.2％、14.2％，而红松幼苗的生物量分别减少3.9％、12.8％；红松、落叶松针叶叶绿素含量以及叶绿素a的相对含量在高浓度CO2下受到影响。

Stem/leaf ratio of all of seven lines was lower than that of the corresponding alfalfa varieties in both cutting. In the first cutting stem/leaf ratio of BHJR5 was the lowest and in the second cutting stem/leaf ratio of BHSHS6 was the lowest.

57个白花品系第一茬和第二茬的茎叶比均小于相应的紫花母株，其中第一茬BHJR5的茎叶比最小，第二茬BHSHS6的茎叶比最小。

Ug99 could be called a superior virulent race to widely-used and Sr31-carrying Chinese wheat cultivars or stem rust resistant sources.The number of virulent genes contained in Ug99 was more than the total carried in all Chinese stem rust races.For instance,the virulence of Sr5,Sr9e or Sr11 was the typical races.However,besides the virulence of Sr5,Sr9e and Sr11,Ug99 contains additional virulence of Sr21,Sr31and Sr38,which have never been found in Chinese stem rust races.

Ug99堪称我国的超毒小种，我国最典型的秆锈菌小种只能分别克服或Sr5或Sr9 e或Sr11单基因抗性，而Ug99不仅具有Sr5、Sr9 e、Sr11的联合毒力，而且还具有Sr21、Sr31、Sr38的联合毒力，而我国从未有小种能克服后者的抗性。1B/1L(含Sr31)易位系曾是我国使用的重要秆锈抗源，必对Ug99高度脆弱，我国118份小麦品种在KARI的测定结果表明，高感品种频率98.3%。

Valve running thrust which represents 90% of the travel of the valve stem can be determined by adding stem load and stem packing friction.

阀门运行推力只是阀门阀杆行程力的90%，因此测算阀门推力时，要加上阀杆负载和阀杆填料摩擦力。

Stem and stem nut rotation combined length of not less than 1.4 times the diameter of the valve stem.

***阀杆与阀杆螺母的旋合长度不得小于阀杆直径的1.4倍。

For rising stem valve, check if the length of stem extension conforms to the length of stem cap.

如果是明杆阀门，应检查阀杆伸出量与阀杆护套的长度是否相符。

"The president is, in effect, allowing federal funding of human embryonic stem cell research to the extent that it's permitted by law -- that is, work with stem cells themselves, not the derivation of stem cells," he said.

他还说，总统允许联邦政府资金用于法律许可范围内的胚胎干细胞研究--这就是说研究干细胞本身，而不是干细胞的来源。

The Geron team began its work with what is known as a Presidential stem cell line — stem cells derived from discarded in vitro fertilization embryos that already existed in 2001 when former President Bush decided to prohibit the use of federal funds to pursue human embryonic stem cell work.

Geron小组用一种被称为总统干细胞开始他们的工作---这种干细胞是从2001年起就存在的被遗弃的体外培养的胚胎中提取的，当时布什总统决定下令禁止使用联邦基金购买人类胚胎干细胞的研究工作。

The Geron team began its work with what is known as a Presidential stem cell line — stem cells derived from discarded in vitro fertilization embryos that already existed in 2001 when former President Bush decided to prohibit the use of federal funds to pursue human embryonic stem cell work.

Geron团队开始他们的研究工作被称为是总统胚胎干细胞株——他们利用试管受精胚胎中丢弃不要的那些干细胞，当时在2001年前任总统布什决定禁止利用联邦基金去从事人类胚胎干细胞工作。

Bobai is characterized by water spinach planted paddy fields, dense leaf stem length, leaf tail taper,鲜绿crisp, the stem pick into a paragraph break, the fracture that split kink, with a sharp knife could not cut the stem I ping.

博白蕹菜的特点是水田栽植，茎长叶密，叶尾尖细，鲜绿脆嫩，把茎蔓摘断成段，其断口即裂开卷缩，用锋利的刀也无法将茎口切平。
