Significant effects of warming onbiomass allocation were only found for the A. faxoniana seedlings grown under lowlight conditions, with significantly increased in leaf mass ratio and decreasedin R/S in responses to warming manipulation. The carbon allocation responses of B.albo-sinensis seedling to warming under full light conditions were similar with theresponse of A. faxoniana seedlings grown under low light conditions. Warmingsignificantly decreased root mass ratio, and increased leaf mass ratioand shoot/root biomass ratio for the B. albo-sinensis seedlings grown under fulllight conditions.

无论在全光或林下低光环境下，增温都促使云杉幼苗将更多的生物量分配到植物地下部分，从而导致幼苗在增温条件下有更高的R／S比；增温仅在林下低光条件下促使冷杉幼苗将更多的生物量投入到植物叶部，从而使幼苗R／S比显著地降低：增温在全光条件下对红桦幼苗生物量分配的影响趋势与冷杉幼苗在低光条件下相似，即增温在全光条件下促使红桦幼苗分配更多的生物量到植物同化部分一叶部。

The remaining TACAM R-2s participated in campaigns of the Romanian Army in Czechoslovakia and Austria, with attrition eventually accounting for all vehicles by the spring of 1945; however, a single TACAM R-2 was recovered from the battlefield at the end of the war and is displayed today at the Militar Muzeul in Bucharest.

罗马尼亚人从战场上回收了一辆TACAM R-2并存放于布加勒斯特的Muzeul Militar National（我怀疑是国家军事博物馆的意思）供人参观。

WVS vacuum circuit breaker can use the R-shaped contact terminal which adopts the unique axial magnetic structure in the world, with independent intellectual property rights.

WVS型真空断路器使用具有自主知识产权的国际上独一无二的纵磁结构的R触头，使用R触头并经过电磁场优化设计的真空灭弧室具有以下优点

The probing behaviors of the tea green leafhopper, Empoasca vitis Gothe, on nine tea cultivars were studied by videotext Direct Current-Electrical Penetration Graph, i. e. DC-EPG. Following seven types of waveforms produced by the leafhopper stylet probing were determined: A, stylet pathway formation; S, salivation when stylets pierce into and stay in phloem; C, active ingestion before stylets reach phloem; E and F, passive ingestion in phloem; R, the insect resting with its stylet inserted into the leaf tissue and NP, not probing.

应用可视DC-EPG方法研究了假眼小绿叶蝉在9个品种茶苗上的口针刺探行为，共发现并初步确定了7种主要波型，即A波、S波、C波、E波、F波和R波、以及非刺探波NP波。A波为刺探波，S波为口针向韧皮部刺探和进入韧皮部中的分泌唾液波，C波为口针到达韧皮部之前的主动取食波，E波和F波为口针在韧皮部中吸收波，R波为取食间歇波。

L Shifting to R while your vehicle is moving forward could damage your transaxle, shift to R only after your vehicle is stopped.

汽车还在向前移动时换到倒挡会损坏变速驱动桥。必须在汽车停下来以后才换到 R 档位。

For the RC simple supported one-way slab under blast loads, a bilinear model is used to simulate the $R$-$y$ curve in the analysis of blast dynamic response.

对爆炸载荷作用下RC板的R-y曲线采用双折线模型，计算不同配筋率的R-y曲线下方面积，面积最大时的配筋率即可定义为相应设计的最佳配筋率。

The studies on metabolic enzymes、synergists and neurobioassays suggest that the monooxygenases、esterase and decreased nerve sensitity are involved in resistance to pyrethroids in the resistant HJ-R strain . The resistance to both organophosphorus and carbamate insecticides is mainly caused by metabolic mechanisms. The significantly synergistic effects of Pbo infer that the resistance to carbamata may be principally attributable to monooxygenases detoxification.

代谢酶系、增效作用以及神经电生理研究表明，HJ-R种群对拟除虫菊酯类杀虫剂的抗性是由多功能氧化酶及酯酶代谢增强、神经敏感性降低几个因子综合作用的结果；对有机磷、氨基甲酸酯类杀虫剂的抗性主要是由代谢机制引起，与靶标部位敏感性降低机制抗性无关，Pbo对HJ-R种群突出的增效作用，表明多功能氧化酶代谢在对灭多威的抗性中可能起主导作用。

SAP's three-tiered architecture is the backbone of an R/3 infrastructure.

SAP的三层结构是R/3基础结构的中枢。它使R/3系统同时具有灵活性、可靠性和开放性。

Background— The INTRINSIC R (Inhibition of Unnecessary R Pacing with ASH in ICDs) study tested the hypothesis that dual-chamber rate-responsie with atrioentricular search hysteresis 60-130 programming is not inferior to single-chamber–40 programming in an implantable cardioerter defibrillator with respect to all-cause mortality and heart failure hospitalizations using an equialence margin of 5%.

背景： INTRINSIC R（ICD非必要右室起搏及房室搜索延迟）研究证实用5%的等效界值计算，就全因死亡率和心衰恶化住院而言，ICD双腔起搏频率应答模式加上房室搜索延迟模式，频率60~130 bpm，不劣于单独心室节律支持模式，频率40 bpm。
