The study on site quality evaluation for dahurian larch (Larix gmelinii Rupr.)

Site quality of larch (Larix gmelinii Rupr.) in Da Xingan Mountain in Inner Mongolia was studied systematically with about 1000 temporary plots and computer software. The nature of site class and site index curve was discussed in view of general mathematical model of height growth. The height growth of dominant tree of four divisions of forest stands were studied and site index tables were constructed respectively. In order to unify the comparing standard and convenience for management in this region, site index table was constucted too. Based on discussing the action and accuracy of forest type, a series of site quality evaluation (forest type-site index class-site index) was suggested. This subject of study is supported by the National Natural Scientific Fund (No. 39270549).     

甘薯新品种综合评价初探

对福建省新育成甘薯品种应用灰色加权关联度分析法进行综合评估，旨在鉴定新品种在丘陵旱地的适应性以及探讨出一种比较适宜的品种评估方法。结果表明，龙薯1号、莆薯41和泉薯647比较适应东南沿海丘陵旱地生产条件，评估结果与品种的实际表现比较一致。

引种草坪草的适应性评价及病害和草害

1997～1998年，对引自丹麦的草地早熟禾、黑麦草、高羊茅、羊茅、紫羊茅、匍匐剪股颖和白三叶等草坪草的品种在兰州市进行了适应性评价。观测、记载了草坪的成坪期、密度、盖度、颜色、质地、越冬率、越夏率、返青期、枯黄期、青缘期等性状；调查了病害的发病率，并对病株进行了病原物的分离、培养和鉴定，统计了各品种带菌率和真菌的分离率；调查了草坪建植与生长过程中的杂草种类和危害程度。结果表明：除Pichwick和Juventus黑麦草以外的所有参试品种均可在兰州地区种植。其中，白三叶的综合性状最好，具有质地柔滑、成坪较快、覆盖度高、枯黄期晚等特点；其次为ORNAMENTAL和SPORT2个混配型草种，成坪快，但抗病性较差；其余各品种建坪后表现好，但成坪速度较慢。草坪生长过程中的主要病害为交链孢叶斑病、离蠕孢叶斑病、德氏霉叶斑病、壳二孢叶枯病、壳二孢叶斑病、镰刀菌枯萎病和叶点霉叶斑病。苗期主要杂革为狗尾草和田旋花。     

对引进草坪草在青海西宁地区的种植品质评价

通过对巴林、亨特、白宝、首相、百琪、百绿、凌志和维加斯8个引进草坪草品种的品质评价，研究了其在西宁地区的坪用性表现以及适应能力，选择出品质较优良的品种。测定了各品种的密度、盖度、质地、耐磨度、颜色、生育型和生长速度以及越冬力。结果表明，供试8个品种中的巴林、亨特、百琪、凌志和维加斯5个品种有较好的越冬能力(WH≥3)。而8个品种均表现出良好的坪用性(TPPl或TPP2≥3)，其中，巴林(Wh＝5，TPP1＝3．6，TPP2＝3.7)、亨特(Wh＝5，TPPl＝3.4，TPP2＝3.6)、百琪(Wh＝4，TPPl＝4.1，TPP2＝3．5)、凌志(Wh＝4，TPPl＝3.0，TPP2＝3．5)和百绿(Wh＝3，TPPl＝4.0，TPP2＝3.1)5个品种无论是越冬力还是坪用性均表现突出，可以作为当地品质较优良的草坪草。     

Performance Evaluation of the ADS 1000 Ventilator Using a Lung Model

A laboratory evaluation was performed to evaluate the performance characteristics of a new veterinary ventilator. The ventilator studied was configured according to manufacturer's directions and attached to a test lung via a pneumotachograph and differential pressure transducer interfaced to a pulmonary mechanics analyzer system. Constant resistance (R=10 cm H₂O/L/sec) and compliance (C=3 ml/cm H₂O) factors were maintained for all trials. The ventilator operated at the manufacturer's preprogrammed parameters. In the first trial, body weight was the only variable. In the second trial, an endotracheal tube was placed in series between the ventilator's breathing circuit and the pneumotachograph. Body weights from 1–20 kgs were evaluated. Mean values for respiratory rate (RR), minute ventilation (VE), inspiratory time (Ti), peak inspiratory pressure (PIP), and peak inspiratory flow (Fpki) displayed on the ventilator control panel; tidal volume (VT), calculated from the displayed minute volume, and identical parameters measured by the pulmonary mechanics system at each body weight, were compared using a two factor analysis of variance. Significant differences (P< 0.05) were found between mean displayed and measured values for RR, PIP, and Fpki.
